Richard Ladner – 91̽News /news Fri, 25 Feb 2022 21:41:10 +0000 en-US hourly 1 https://wordpress.org/?v=6.9.4 Four 91̽faculty members, incoming Burke Museum leader named 2021 AAAS Fellows /news/2022/01/26/2021-aaas-fellows/ Wed, 26 Jan 2022 21:03:23 +0000 /news/?p=77100 Four current 91̽ faculty members and the incoming executive director of the UW’s have been named AAAS Fellows, according to a Jan. 26 by the American Association for the Advancement of Science. They are among 564 new fellows from around the world elected in 2021, who are recognized for “their scientifically and socially distinguished achievements” in science and engineering.

The UW’s new AAAS Fellows are:

, a professor of biology and resident scientist at the UW’s , is honored for her research contributions in biomechanics and ecophysiology, as well as efforts to promote diversity and inclusion in science. Her research has shown how marine life in near-shore ecosystems, especially invertebrates and seaweeds, respond to both short-term fluctuations in their environment and long-term shifts due to climate change. Carrington’s research has illuminated the many ways that expected shifts in oceans due to climate change — including heat waves and increases in dissolved CO2 — will negatively impact shellfish, algae and other organisms in coastal ecosystems and aquaculture. Her investigations of the biomaterials that mussels use to adhere to underwater surfaces have also aided the design of wet adhesives and antifouling surfaces for biomedical and maritime applications. A member of the 91̽faculty since 2005, Carrington also served as a program director in the National Science Foundation’s Directorate for Biological Sciences from 2016 to 2019.

Gabriela Chavarria, the executive director of the Burke Museum, is honored for her work on ecosystem sustainability, as well as leadership in education and conservation programs. Chavarria is an expert on native bees. She studies tropical bumblebees, and has long advocated for conservation of native pollinators. Chavarria was also trained as wood anatomist, and has helped to combat illegal traffic of hardwoods. An interest in conservation and policy led Chavarria to work for the U.S. Fish and Wildlife Service as a science adviser to the director, and later became a senior science adviser and head of forensic science at the agency’s wildlife forensic laboratory in Ashland, Oregon. Since 2018, she has served as Chief Curator and Vice President of the Science Division at the Denver Museum of Nature & Science. In announcing Chavarria as the next executive director of the Burke Museum last month, Dianne Harris, Dean of Arts and Sciences at the UW, said: “Chavarria’s experience as a museum administrator, scholar and visionary leader in the scientific community uniquely positions her to lead the Burke in its exciting next chapter.” That chapter commences March 1.

, a professor of chemistry, was selected for her studies of a large class of enzymes that promote biochemical reactions in living cells for functions such as suppressing tumor growth, removing toxic compounds and synthesizing antibiotics. Kovacs’ research focuses on how the bonds between atoms in these enzymes shift as they catalyze reactions, revealing details of the underlying mechanism that these key cellular players use to carry out their functions. She is also studying how oxygen atoms form bonds with one another — a process that occurs naturally during photosynthesis, but details of which are poorly understood. Elucidating this mechanism could help the green energy industry develop efficient fuel-storage technologies. Kovacs joined the 91̽faculty in 1988 and has previously chaired the American Chemical Society’s Division of Inorganic Chemistry.

, a professor emeritus in the Paul G. Allen School of Computer Science & Engineering, is recognized for his advocacy and inclusion efforts for people with disabilities in computer science and related fields. Trained in mathematics, Ladner spent much of his career researching fundamental issues in computer science — including optimization, computational complexity and distributed computing. He also co-founded what is now the Theory of Computation Group at the Allen School. In the latter half of his career, Ladner worked largely on accessibility in computer science. These endeavors included development of numerous tools to perform specific tasks, for example: translating textbook figures into formats accessible to persons with disabilities, or allowing people to communicate via cell phones using American Sign Language. Among numerous honors, Ladner was a Guggenheim Fellow, a Fulbright Scholar, an Association for Computing Machinery Fellow and an IEEE Fellow. He joined the 91̽faculty in 1971 and retired as a professor emeritus in 2017.

, a professor of chemistry, is honored for developing new techniques and tools in chemistry, particularly novel algorithms and methods for electron paramagnetic resonance spectroscopy. Stoll uses this unique form of spectroscopy — which can explore the microscopic details and fast dynamics of chemical compounds that have unpaired electrons — to measure distances as small as a few nanometers, which is roughly 1/5000th the diameter of the thinnest human hair. Stoll applies this to study the structure of cellular proteins and discern the conformational changes that they undergo while performing their functions, such as catalyzing reactions or regulating heartbeat. These fundamental insights broaden our understanding of the human body and how it works. Stoll joined the 91̽faculty in 2011.

Many mobile health apps neglect needs of blind users /news/2015/07/16/many-mobile-health-apps-neglect-needs-of-blind-users/ Thu, 16 Jul 2015 16:45:44 +0000 /news/?p=37839

More Americans are using mobile devices and other technologies at home, from diet and exercise to sleep patterns and bloodwork.

Because people who are blind or have low vision are more likely to have health problems such as obesity or diabetes, it’s especially important that mobile health (mHealth) applications — health tracking sensors that connect with smartphone apps — work for those users.

Yet 91̽ researchers who conducted the first academic review of nine mHealth applications on the market in March 2014 found none met all the criteria that would make them fully accessible to blind customers.

In a in the 2015 issue of the , they investigated nine common iPhone mHealth applications that upload data from blood pressure and blood sugar monitoring devices. Accessibility shortcomings ranged from improperly labeled buttons to confusing layouts that don’t work well with iPhone VoiceOver or Android TalkBack services that “read” information on the phone screen.

“We wanted to see if these health applications would be out-of-the-box accessible, and most really weren’t,” said lead author , a 91̽computer science and engineering doctoral student. “They made a lot of amateur mistakes that people make when they build apps.”

The researchers also concluded it would take little effort for developers to make mainstream health sensors fully accessible to blind smartphone users — largely by following accessibility guidelines already established by Apple and the federal government.

“It wouldn’t have been hard to make their apps accessible by making that a priority in the first place. They could have been heroes from the get-go,” said senior author , a 91̽computer science professor who to make technologies more broadly accessible.

The research team — which includes co-author , a 91̽human-centered design and engineering doctoral student — rated four iPhone glucose monitoring apps (iBGStar, Glooko Logbook, Telcare, iGluco) and five blood pressure monitoring apps (iHealth BP Monitor, Withings, iBP, myVitali, Digifit).

Confronted with this confusing layout, the iPhone’s VoiceOver program that assists blind users would read the green portion as: “87 2:16 p.m. before breakfast fasting mgdl 5 13 15 glucose manual.” Photo: Lauren Milne, 91̽

They developed seven criteria for making apps accessible to low-vision users, borrowing from to help app developers take advantage of the phone’s built-in accessibility capabilities and that technologies purchased by the federal government must meet.

Those include buttons that are programmed correctly to tell a user what to do with them, hints that help with navigation and grouping items so they make sense to screen readers that tell blind users what icon their finger is on or describe aloud what’s happening on the screen.

Those typically “read” from the top left to the bottom right of a screen. If an app hasn’t been laid out with the iPhone’s VoiceOver program in mind, for example, a blood pressure reading of 120 mmHg over 70 mmHg and a heart rate of 80 beats per minute taken on Sept. 28 might be communicated to someone who can’t see as “120, 70, 80, September 28, mmHg, mmHg, beats/minute.”

At the time that the mHealth apps were tested in March 2014, one blood glucose monitoring app — the Glooko Logbook — met all of the accessibility criteria except for one. The other apps failed to meet at least half the accessibility guidelines. The study did not examine other accessibility features such as the ability to zoom or the use of large or high-contrast print, and researchers say it’s possible manufacturers have made accessibility upgrades to more recent versions of the apps.

In fact, when app developers simply “borrowed” standard iPhone operating system elements, the products were more accessible, the researchers found. When they designed custom elements, they rarely included the necessary information to make them work with screen readers that assist low-vision users.

“If people just used the basic widgets and things that Apple provides, they’d have better results,” said Ladner. “But the number of app developers has increased, and most of them are thinking about trying to make things pretty. They’re not thinking about all the users.”

Competitive STEM program at 91̽targets deaf, hard of hearing students /news/2013/06/27/competitive-stem-program-at-uw-targets-deaf-hard-of-hearing-students/ Thu, 27 Jun 2013 19:48:41 +0000 /news/?p=26236

Finals are barely over for 91̽ student Jessie Zhang and already she’s excited to be back on campus. Zhang, who just finished her freshman year, will learn programming skills, meet mentors in the tech industry and try her hand at animation – all while speaking with her cohort and advisers through signing and technologies that help her communicate.

Zhang joined 16 other deaf and hard of hearing students from around the country June 24 to participate in an intensive summer of computer science courses, industry tours and networking.

“I’m hoping to get a head start on what I want to pursue at the UW,” Zhang said.

The 91̽program, called , is the only one of its kind in the nation that offers a full quarter of academic credit to incoming college students or those who just finished their first year.

Students will present their animation films at 7 p.m. Aug. 16, in the UW , room 105.

It also gives deaf students a chance to explore an academic field they may not have already considered, said , a 91̽professor of computer science and engineering who started the academy six years ago.

“It has many facets and a richness that many programs don’t have,” Ladner said. “It really opens up their worldview to what they can do.”

The program, which runs through Aug. 23, will end after this year. It was the brainchild of Ladner, born to two deaf parents, who has decided after 42 years at the 91̽that his time as program lead is complete.

Still, this year’s class is the largest and most competitive yet, said Robert Roth, the academy’s director. After its final summer, the program will have graduated more than 80 students.  A number of those alumni have majored in computer science fields and have returned to the Seattle area to work.

Matt Starn, a software development engineer at Microsoft, was a summer academy student during the first year of the program in 2007. He came after his sophomore year at University of California, Los Angeles, where he hadn’t yet decided what to major in. After the summer quarter at the UW, Starn decided to transfer to Rochester Institute of Technology, where he studied computer science.

“The summer academy played a big role in identifying computer science and helping me pursue it,” Starn said.

The program’s field trips around the city and networking visits to local companies helped Starn “fall in love” with Seattle, he said, which is partly why he returned to the area for work.

Summer academy students live on the 91̽campus and take a nine-week computer programming course for college credit, plus a certificate class in animation. They produce at the end of the quarter and present them at a community event.  Graduate students and alumni of the program serve as tutors and mentors throughout the summer, and participants visit a number of local tech companies, including Google, Microsoft and Adobe.

Graduates of the program’s first year are starting to land jobs or enroll in graduate programs. Some, like Starn, are at tech companies, while many are pursuing degrees at the Rochester Institute of Technology, which houses the . Others are completing programs at Massachusetts Institute of Technology and Stanford University.

Before the 91̽experience, they often were the only deaf or hard of hearing students in their high schools, so learning to communicate within a deaf community is a big part of the program, Ladner said. Some learn American Sign Language for the first time.

“This is the beginning of their networking lives,” he said.

Google software engineer has helped with practically every aspect of the summer program its first several years while she was a 91̽doctoral student in computer science and engineering. She has seen students forge lasting friendships and land highly competitive jobs through networking.

“The transition to college can be a little extra daunting for deaf and hard of hearing students,” Cavender said. “This program helps students navigate the hurdles and introduces them to other students with similar backgrounds and interests.”

The summer academy is funded by the Bill & Melinda Gates Foundation, the Johnson Scholarship Foundation and the National Science Foundation. It’s part of the 91̽, which is a collaboration of the 91̽department of computer science and engineering and the Opportunities, Internetworking, and Technology center.

Crowdsourcing site compiles new sign language for math and science /news/2012/12/07/crowdsourcing-sit-compiles-new-sign-language-for-math-and-science/ Fri, 07 Dec 2012 18:00:14 +0000 /news/?p=20670 A multimedia feature published this week in the New York Times, “,” outlines efforts in the United States and Europe to develop sign language versions of specialized terms used in science, technology, engineering and mathematics.

The article shares newly defined signs for terms like “light-year,” “organism” and “photosynthesis.” It also describes a successful crowdsourcing effort started at the 91̽ in 2008 that lets members of the deaf and hard-of-hearing community build their own guide to the evolving lexicon of science.

A screen capture from the ASL-STEM Forum.

“It’s not a dictionary,” explained , a 91̽professor of computer science and engineering. “The goal of the forum is to be constantly changing, a reflection of the current use.”

A scientific and technical dictionary for American Sign Language has existed since the late 1990s.  It is called Lexicon, launched by , an early proponent of science in the deaf community and a professor at the National Technical Institute for the Deaf at Rochester Institute of Technology.

But a dictionary can’t include the newest terms, Ladner said, and many graduate students won’t find the specialized terms used in their chosen fields. For example, Ladner helped organize a 2008 workshop where a deaf scientist said only about one-quarter of his field’s specialized terms existed in his native language, American Sign Language, or ASL. Many workshop participants reported that at some point they had had to work with their interpreters to develop their own code words.

That year, with funding from Google Corp. and the National Science Foundation, Ladner’s group launched the , an online compilation of signs used in science, technology, engineering and math that is more like Wikipedia or the Urban Dictionary.

“The goal was to have one place where all these signs could be,” Ladner said. “We’re not trying to decide on new signs but just collect the ones that are in current use.”

The site lists 6,755 terms from biology, chemistry, engineering, math and computer science textbooks. Of those, about 2,800 have video entries, some with multiple entries. Partnerships with the country’s two largest higher education institutions for deaf and hard-of-hearing students have helped provide content.

Collaborators include , a 91̽alumna and biology professor at Gallaudet University in Washington, D.C., and Lang and at Rochester’s National Technical Institute for the Deaf.

Visit the forum to see a sign for “,” “” and “,” none of which is listed in the Science Signs dictionary. Terms still seeking an ASL translation include “” and “.”

Anyone can visit the forum, but to add signs a user must create a free account then record a short video using a computer’s camera that can be reviewed and uploaded. People also can rate and comment on signs uploaded by other users.

Richard Ladner and students

Ladner hopes the recent article will spur interest and encourage people to suggest more entries among the remaining terms. He is seeking funding to update the site, and hopes it will reach critical mass among ASL speakers in scientific and technical fields.

Between 2006 and 2010, U.S. institutions awarded 301 doctorate degrees in STEM fields to people who are deaf or hard-of-hearing, Ladner said. Because that number includes hard-of-hearing, the number of science PhDs who use ASL is likely much lower. Many members of that community are geographically scattered, and to make matters worse, American Sign Language and British Sign Language have their own technical lexicons.

“I hope ASL-STEM Forum helps more deaf students become scientists and engineers,” Ladner said. “And as more deaf students enter these fields they will hopefully contribute to the forum, making it sustainable and useful over time.”

“,” CHI 2010

Now working on the forum at the 91̽are , a doctoral student in computer science and engineering, and John Norberg, a 91̽undergraduate in math who is minoring in ASL. Early members of the 91̽team include computer science and engineering doctoral students , now working on accessibility projects at Google, and , now an accessibility researcher at the University of Rochester in New York; and former 91̽undergraduates , Michelle Shepardson and Jessica Dewitt.

Ladner runs a national to encourage deaf and hard-of-hearing students to pursue careers in computer science, and he leads , a larger UW-based national effort to encourage people with disabilities to pursue computing fields. His group is also involved in a number of that combine computing, mobile technology and accessibility.

Josiah Cheslik, a 91̽junior and volunteer in the MobileASL field study, demonstrates using the phone to communicate in his native language. He is signing with Pete Michor, seen in the background, another participant in the study.

The 91̽field test is using phones imported a couple of years ago from Europe, but MobileASL software could potentially run on any device.

91̽ engineers are developing the first device able to transmit American Sign Language over U.S. cellular networks. The tool is just completing its initial field test by participants in a 91̽summer program for deaf and hard-of-hearing students.

 “This is the first study of how deaf people in the United States use mobile video phones,” said project leader Eve Riskin, a 91̽professor of electrical engineering.

The MobileASL team has been working to optimize compressed video signals for sign language. By increasing image quality around the face and hands, researchers have brought the data rate down to 30 kilobytes per second while still delivering intelligible sign language. MobileASL also uses motion detection to identify whether a person is signing or not, in order to extend the phones’ battery life during video use.

Transmitting sign language as efficiently as possible increases affordability, improves reliability on slower networks and extends battery life, even on devices that might have the capacity to deliver higher quality video.

This summer’s field test is allowing the team to see how people use the tool in their daily lives and what obstacles they encounter. Eleven participants are testing the phones for three weeks. They meet with the research team for interviews and occasionally have survey questions pop up after a call is completed asking about the call quality.

The field test began July 28 and concludes this Wednesday. In the first two and a half weeks of the study, some 200 calls were made with an average call duration of a minute and a half, researchers said. A larger field study will begin this winter.

“We know these phones work in a lab setting, but conditions are different in people’s everyday lives,” Riskin said. “The field study is an important step toward putting this technology into practice.”

Participants in the current field test are students in the 91̽Summer Academy for Advancing Deaf and Hard of Hearing in Computing. The academy accepts academically gifted deaf and hard-of-hearing students interested in pursuing computing careers. Students spend nine weeks at the 91̽taking computer programming and animation classes, meeting with deaf and hard-of-hearing role models who already work in computing fields, 91̽graduate students and visiting local computer software and hardware companies.

Most study participants say texting or e-mail is currently their preferred method for distance communication. Their experiences with the MobileASL phone are, in general, positive.

“It is good for fast communication,” said Tong Song, a Chinese national who is studying at Gallaudet University in Washington, D.C. “Texting sometimes is very slow, because you send the message and you’re not sure that the person is going to get it right away. If you’re using this kind of phone then you’re either able to get in touch with the person or not right away, and you can save a lot of time.”

Josiah Cheslik, a 91̽undergraduate and past participant in the summer academy who is now a teaching assistant, agreed.

“Texting is for short things, like ‘I’m here,’ or, ‘What do you need at the grocery store?'” he said. “This is like making a real phone call.”

As everyone knows, text-based communication can also lead to mix-ups.

“Sometimes with texting people will be confused about what it really means,” Song said. “With the MobileASL phone people can see each other eye to eye, face to face, and really have better understanding.”

Some students also use video chat on a laptop, home computer or video phone terminal, but none of these existing technologies for transmitting sign language fits in your pocket.

Cheslik recounts that during the study one participant was lost riding a Seattle city bus and the two were able to communicate using MobileASL. The student on the bus described what he was seeing and Cheslik helped him navigate where he wanted to go.

Newly released high-end phones, such as the iPhone 4 and the HTC Evo, offer video conferencing. But users are already running into hitches — broadband companies have blocked the bandwidth-hogging video conferencing from their networks, and are rolling out tiered pricing plans that would charge more to heavy data users.

The 91̽team estimates that iPhone’s FaceTime video conferencing service uses nearly 10 times the bandwidth of MobileASL. Even after the anticipated release of an iPhone app to transmit sign language, people would need to own an iPhone 4 and be in an area with very fast network speeds in order to use the service. The MobileASL system could be integrated with the iPhone 4, the HTC Evo, or any device that has a video camera on the same side as the screen.

“We want to deliver affordable, reliable ASL on as many devices as possible,” Riskin said. “It’s a question of equal access to mobile communication technology.”

Jessica Tran, a doctoral student in electrical engineering who is running the field study, is experimenting with different compression systems to extend the life of the battery under heavy video use. Electrical engineering doctoral student Jaehong Chon made MobileASL compatible with H.264, an industry standard for video compression. Tressa Johnson, a master’s student in library and information science and a certified ASL interpreter, is studying the phones’ impact on the deaf community.

The MobileASL research is primarily funded by the National Science Foundation, with additional gifts from Sprint Nextel Corp., Sorenson Communications and Microsoft Corp. Collaborators at the 91̽are Richard Ladner, professor of computer science and engineering, and Jacob Wobbrock, assistant professor in the Information School.

The Summer Academy for Advancing Deaf and Hard of Hearing in Computing is applying for a third round of funding from the National Science Foundation. Additional support for this year’s program came from the Johnson Family Foundation, the Bill and Melinda Gates Foundation, Cray Corp., Oracle Corp., Google Corp. and SignOn Inc.

‘Can you see me now?’ Sign language over cell phones comes to United States /news/2008/08/21/can-you-see-me-now-sign-language-over-cell-phones-comes-to-united-states/ Thu, 21 Aug 2008 00:00:00 +0000 /news/2008/08/21/can-you-see-me-now-sign-language-over-cell-phones-comes-to-united-states/

Doctoral student Anna Cavender, who learned sign language after joining the MobileASL group, demonstrates the device. Users can hold the phone in front of them and sign with one hand but most prefer to set the phone on a table and sign with both hands.

A group at the 91̽ has developed software that for the first time enables deaf and hard-of-hearing Americans to use sign language over a mobile phone. 91̽engineers got the phones working together this spring, and recently received a National Science Foundation grant for a 20-person field project that will begin next year in Seattle.

This is the first time two-way real-time video communication has been demonstrated over cell phones in the United States. Since posting a video of the working prototype on YouTube, deaf people around the country have been writing on a daily basis.

“A lot of people are excited about this,” said principal investigator Eve Riskin, a 91̽professor of electrical engineering.

The video is posted at .

For mobile communication, deaf people now communicate by cell phone using text messages. “But the point is you want to be able to communicate in your native language,” Riskin said. “For deaf people that’s American Sign Language.”

Video is much better than text-messaging because it’s faster and it’s better at conveying emotion, said Jessica DeWitt, a 91̽undergraduate in psychology who is deaf and is a collaborator on the MobileASL project. She says a large part of her communication is with facial expressions, which are transmitted over the video phones.

Low data transmission rates on U.S. cellular networks, combined with limited processing power on mobile devices, have so far prevented real-time video transmission with enough frames per second that it could be used to transmit sign language. Communication rates on United States cellular networks allow about one tenth of the data rates common in places such as Europe and Asia (sign language over cell phones is already possible in Sweden and Japan).

Even as faster networks are becoming more common in the United States, there is still a need for phones that would operate on the slower systems.

“The faster networks are not available everywhere,” said doctoral student Anna Cavender. “They also cost more. We don’t think it’s fair for someone who’s deaf to have to pay more for his or her cell phone than someone who’s hearing.”

The team tried different ways to get comprehensible sign language on low-resolution video. They discovered that the most important part of the image to transmit in high resolution is around the face. This is not surprising, since eye-tracking studies have already shown that people spend the most time looking at a person’s face while they are signing.

The current version of MobileASL uses a standard video compression tool to stay within the data transmission limit. Future versions will incorporate custom tools to get better quality. The team developed a scheme to transmit the person’s face and hands in high resolution, and the background in lower resolution. Now they are working on another feature that identifies when people are moving their hands, to reduce battery consumption and processing power when the person is not signing.

The team is currently using phones imported from Europe, which are the only ones they could find that would be compatible with the software and have a camera and video screen located on the same side of the phone so that people can film themselves while watching the screen.

Mobile video sign language won’t be widely available until the service is provided through a commercial cell-phone manufacturer, Riskin said. The team has already been in discussion with a major cellular network provider that has expressed interest in the project.

The MobileASL team includes Richard Ladner, a 91̽professor of computer science and engineering; Sheila Hemami, a professor of electrical engineering at Cornell University; Jacob Wobbrock, an assistant professor in the UW’s Information School; 91̽graduate students Neva Cherniavsky, Jaehong Chon and Rahul Vanam; and Cornell graduate student Frank Ciaramello.

History shows many deaf artists and inventors, including Thomas Edison and Ludwig van Beethoven. So why are deaf people mostly absent from today’s digital revolution in communications technology? The 91̽is spearheading a national effort to encourage deaf and hard-of-hearing students to pursue computer science.

This summer the 91̽is offering an intense, nine-week computer science academy for tech-savvy students in their late teens or early twenties who are deaf or hard-of-hearing. The inaugural Summer Academy for Advancing Deaf & Hard of Hearing in Computing kicked off in June, welcoming 10 accomplished students from around the country. The curriculum includes a first-year computer programming class and a digital animation course. By the end of summer the students will have created animated films, which they will show off later this month at a public screening.

The academy was created to boost the number of deaf and hard-of-hearing students in computer science. Numbers right now are very low, said Program Director Richard Ladner, a 91̽computer science professor. This summer represents the first of at least two years’ funding for the academy, which is run through the Disabilities, Opportunities, Internetworking and Technology (DO-IT) office and the Department of Computer Science & Engineering.

“The first goal is to build up the capacity of these students to become successful in computer science,” Ladner said. “A secondary goal is to give them the excitement, give them the motivation — so they have the capacity and the desire to succeed.”

So far, he said, he’s been pleased with the students’ progress.

In a classroom in the Paul Allen Center, the instructor flicks the classroom lights on and off twice to get the students’ attention. The scene is familiar — the teacher lectures, the students shy away from presenting their work. But the classroom is a visual cacophony. The instructor, computer science senior undergraduate Michael Carson, asks students to describe the story line of their animated films while interpreter Heather Benjamin stands at the front of the class and translates into American Sign Language. At the same time, a computer-assisted real-time translator sends printed transcripts to an overhead screen. One student who is both deaf and blind follows the lecture by keeping his fingers on top of an interpreter’s hands, in order to sense the movements.

“Communication generally isn’t a problem at all,” Carson said. The experience is very similar to helping teach the animation course during the regular school year, he added.

The academy is the latest in Ladner and colleague Sheryl Burgstahler’s quest to recruit more diverse students to the field of computer science (see ). The participants in this year’s academy range in age from 16 to 24, and have different levels of hearing ability. They were selected because they had exceptional math and science skills and came recommended by their teachers. This year all the participants are male — organizers say they hope to change this in future years.

Some were interested in computers and have studied the subject before. Michael McAllister, 19, a computer science major at High Point University in Charlotte, NC, said he’s been interested in computers since the seventh grade.

For others, this is their first chance to study computers. Lorne Farovitch, 16, a high school student from Tucson, Ariz., says he’s always liked playing video games and wondered what was going on behind the screen. The programming class “helped me to know the inside of the computer,” he said. Asked to name the academy’s high points, he said: “If I write a program and at the end it actually works, that’s my favorite part.”

So far, the students have gone on field trips to Microsoft, Boeing and Adobe and met with deaf or hard-of-hearing employees at Microsoft and Boeing. Professionals working at Oracle, IBM and Cray also traveled to the 91̽to meet the class and speak about their experiences as deaf or hard-of-hearing people in the computing industry.

“One thing I like about this program is it really provided a lot of role models for us,” said Bobby Jackson, 19. “In Memphis, the only deaf role models I know are teachers,” he said. “I came here … and realized that computer science really applies to modern society,” he said. “So I became really fascinated by it.”

The students’ costs are covered through the National Science Foundation grant that funds the program. But the students are hardly on vacation. When asked what they have been doing in the evenings, the students respond through an interpreter that they have been catching up on their animation storyboard and the Java programming class. In between, they have also visited the Space Needle, gone on the Ride the Duck aquatic bus tour and experienced campus life. A few students are teaching sign language to the barista working in the Paul Allen Center lobby.

For many, it’s their first experience at a large university, and their first experience living in a major city like Seattle. “It’s nice. It’s big,” said Adam Zaelit, 20, a student at Stephen Austin State University in Keller, Tex.

The deaf and hard-of-hearing community holds a special interest for Ladner. Both of his parents were deaf and taught in deaf schools. They attended the country’s only university for the deaf, Gallaudet University in Washington, D.C., when it was still a college. Ladner’s father went on to earn a degree at the University of California, Berkeley at a time when the school offered no accommodations for people with disabilities — his father simply read the textbooks and then wrote the exams without ever attending a lecture (see earlier  about Ladner and his family).

The academy hopes to address a longtime deficit of deaf people in computing fields.

“If deaf or hard-of-hearing people are interested in computers, they’re told about repairing computers. And there’s so much more they could get involved in,” said program coordinator Rob Roth, a part-time employee at the 91̽who is himself deaf.

There are no exact statistics on the number of deaf and hard-of-hearing students in U.S. universities. Raja Kushalnagar, a doctoral student in computer science at the University of Houston, says he currently knows of only one other deaf doctoral student in computer science.

Kushalnagar is employed as a teaching assistant with the academy. “He’s way overqualified,” Ladner said. Kushalnagar studies how brain images differ in blind people and deaf people. He applied for the position because he wanted to participate in the summer academy and act as a mentor to the younger students.

“It is lonely as a deaf academic in the computer science field,” Kushalnagar said. “Many deaf and hard-of-hearing people do their research in psychology, social work or deaf education.” He believes computing research offers a chance to make a difference also.

To celebrate the completion of the summer session, the class will hold a free public screening of their animations on Friday, Aug. 17, at 7 p.m. in 125 Electrical Engineering. Doors open at 6:30 p.m. The program includes a short video of this year’s program that will be turned into a promotional film for the academy. Refreshments will follow.

Sign of caring: Ladner learns parents’ language, contributes to their community /news/2004/05/20/sign-of-caring-ladner-learns-parents-language-contributes-to-their-community/ Thu, 20 May 2004 00:00:00 +0000 /news/2004/05/20/sign-of-caring-ladner-learns-parents-language-contributes-to-their-community/

Richard Ladner converses in American Sign Language with student Patty Liang.

In a way, Richard Ladner inherited his volunteer interests.

The hearing son of deaf parents, the 91̽computer science and engineering professor has donated considerable time to the deaf community for the last 24 years. But it was a legacy he didn’t pick up until long after he’d left home and started a career of his own.

That’s when he started to talk to his parents in their language for the first time.

“I didn’t learn sign language growing up,” Ladner said. “That was in the age of oralism, when all deaf people were encouraged to speak and to read the lips of hearing people instead of sign. There wasn’t the recognition of signing as a language then, or the encouragement to learn it.”

So, both his parents spoke. His father hadn’t become deaf until the age of 4, so he had already learned to speak, Ladner explained, and his mother — deaf from 6 months — learned to speak and read lips. Both parents used American Sign Language as well, and taught at the California School for the Deaf in Berkeley, but only one of their four children — Ladner’s older sister — learned how to sign.

That made her the interpreter for the family, especially between Ladner’s father and his kids because he didn’t read lips. But at the time there was no thought of teaching all the children sign language.

“In those days, deaf parents just wanted their hearing kids to be like other kids,” Ladner said.

And indeed, his parents succeeded at that. Ladner said he didn’t really feel “different” until adolescence, when he began to take notice of the difficulties his parents encountered in the hearing world.

Still, when he left home, not speaking sign language and with no deaf friends, he wasn’t really anticipating connections to the deaf community.

It was in 1980, when Ladner was early in his career at the UW, that he began to reconsider learning to sign. His parents were getting older, and he wanted to be able to communicate with them more fully.

“Knowing the power of language, it became more important to me,” he said. “Having a common language between people is incredible. I think that goes across cultures. If my parents spoke Japanese, it would be the same thing.”

So Ladner enrolled in American Sign Language classes at Seattle Central Community College. And although it was easier for him to learn because of his early exposure to his parents and their friends, he still found the language challenging. He said that’s because you use your eyes to receive it and hearing people are not used to doing that. Even today, he claims his fluency is only “moderate.”

“I have a hard time with finger spelling and colloquialisms,” he said.

Ladner’s fluency was challenged a few years later when he applied for and received a Guggenheim fellowship to teach at Gallaudet, the only university in the country that is primarily for the deaf. He was teaching the theory of computation, which requires the use of mathematical concepts.

“There are signs for technical terms in classes like calculus, but not for something like this,” he said. “I had to work with the students to invent some signs to use.”

But he enjoyed the experience. Gallaudet was his parents’ alma mater, so he’d heard about it for years. He’s returning to the school this month to see a friend receive an honorary degree.

The friend is Marilyn Smith, who was one of Ladner’s first sign language teachers, and also a person who recruited him to several volunteer causes.

“I did some fund raising for the American Association of the Deaf Blind convention that was here in Seattle in 1984,” Ladner recalled. “I was on a committee that worked on that. It was quite exciting.”

More recently, he’s become involved with fund raising for the Abused Deaf Women’s Advocacy Services (ADWAS). As its name implies, this is an organization that helps abused women who are also deaf to get out of their abusive situations. Domestic violence is a particular problem for deaf women, Ladner said, because these women are likely to feel isolated. If they go to a regular domestic violence agency, there may not always be an interpreter available to help them communicate.

Right now, ADWAS is trying to raise $7.6 million to build transitional housing that will be run by the YWCA. When completed, the facility will be the first of its kind in the nation. Ladner is a co-chair of the steering committee for the capital campaign.

Except for his stint at Gallaudet, Ladner’s interest in deaf concerns hasn’t intersected much with his career. As a theorist (his degree is in math), he isn’t usually involved with technological advances that can help the deaf, although back in the 80s, he worked on an IBM project to develop a network for the deaf-blind using Braille displays and large print.

And now another possibility is in the offing. “A couple of my colleagues came to me with the idea that we should try to do data compression for video over cell phones,” Ladner said. “Video already exists for cell phones but it’s low quality. What we’d like to do is work on higher quality.”

High quality video would permit signing over the phone. The group has applied to the National Science Foundation for a grant to fund the project.

In the meantime, Ladner continues to work on ADWAS fund raising and lobbies hard to get the 91̽to offer classes in American Sign Language.

Currently, the University accepts American Sign Language as a foreign language for admission and for graduation but doesn’t offer the language itself.

It’s not surprising Ladner would be passionate about sign language. He still remembers the emotional day he went home and used the language with his parents for the first time.

“It cemented a bond between us that hadn’t really been there before,” he said.
