• Animations at Your Fingertips: Using a Refreshable Tactile Display to Convey Motion Graphics for People who are Blind or have Low Vision

  Leona Holloway, Swamy Ananthanarayan, Matthew Butler, Madhuka Thisuri De Silva, Kirsten Ellis, Cagatay Goncu, Kate Stephens, Kim Marriott · 2022 · Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '22)

  This paper investigates the potential of refreshable tactile displays (RTDs) to convey animated graphics to people who are blind or have low vision — a capability that has been virtually impossible with traditional static tactile media. While tactile graphics produced on swell…

• Empirical Investigation of Users' Preferred Timing Parameters for American Sign Language Animations

  Sedeeq Al-khazraji, Becca Dingman, Matt Huenerfauth · 2020 · Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems (CHI EA '20)

  This CHI 2020 Late-Breaking Work (7 pages) investigates a narrow but consequential HCI question: what timing values should be used when generating American Sign Language (ASL) animations from a script, so that Deaf viewers find them comfortable to watch? ASL is a primary…

• Modeling the Speed and Timing of American Sign Language to Generate Realistic Animations

  Sedeeq Al-khazraji, Larwan Berke, Sushant Kafle, Peter Yeung, Matt Huenerfauth · 2018 · Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '18)

  This paper addresses the challenge of generating realistic computer animations of American Sign Language (ASL) by automatically modeling three critical timing parameters: where prosodic pauses should be inserted, how long those pauses should last, and how the signing speed of…

• Designing an Animated Character System for American Sign Language

  Danielle Bragg, Raja Kushalnagar, Richard Ladner · 2018 · Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2018)

  This University of Washington and Gallaudet University paper introduces the first animated character system prototype for sign language, addressing the fundamental problem that sign languages — used by approximately 70 million people worldwide as their primary language — lack a…

• Demographic and Experiential Factors Influencing Acceptance of Sign Language Animation by Deaf Users

  Hernisa Kacorri, Matt Huenerfauth, Sarah Ebling, Kasmira Patel, Mackenzie Willard · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper addresses a critical methodological gap in sign language animation research: the lack of standardized reporting on participant characteristics that may influence evaluation results. Sign language animation technology—which automatically synthesizes signing from…

• Towards Fully Automated Motion Capture of Signs -- Development and Evaluation of a Key Word Signing Avatar

  Simon Alexanderson, Jonas Beskow · 2015 · ACM Transactions on Accessible Computing (TACCESS)

  This research develops a cost-effective method for capturing sign language motion to animate a signing avatar for the Tivoli project—a game-based learning environment teaching Key Word Signing (KWS) to children with communication disabilities including developmental disorders,…

• Implementation and Evaluation of Animation Controls Sufficient for Conveying ASL Facial Expressions

  Hernisa Kacorri, Matt Huenerfauth · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS '14)

  This ASSETS 2014 short paper (2 pages) reports an infrastructure contribution to sign-language-animation research: the authors extended an existing virtual human character (Max, on the open-source EMBR animation platform) with a full set of MPEG-4 Facial Action Parameter (FAP)…

• Comparing Native Signers' Perception of American Sign Language Animations and Videos via Eye Tracking

  Hernisa Kacorri, Allen Harper, Matt Huenerfauth · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper investigates whether eye tracking can serve as an alternative or complementary evaluation method for assessing the quality of synthesized American Sign Language (ASL) animations. Computer-generated ASL animations offer accessibility benefits for deaf individuals with…

• Data-Driven Synthesis of Spatially Inflected Verbs for American Sign Language Animation

  Pengfei Lu, Matt Huenerfauth · 2011 · ACM Transactions on Accessible Computing

  This paper addresses a critical accessibility challenge: most deaf individuals in the US have limited English literacy (the majority of deaf high school graduates read at a fourth-grade level), making written web content inaccessible. While sign language animation offers a…

• Accurate and Accessible Motion-Capture Glove Calibration for Sign Language Data Collection

  Matt Huenerfauth, Pengfei Lu · 2010 · ACM Transactions on Accessible Computing

  This paper addresses a critical bottleneck in sign language technology research: the calibration of motion-capture gloves used to record hand movements for ASL animation and recognition systems. Motion-capture data enables the development of sign language animations that can…

• Evaluation of a psycholinguistically motivated timing model for animations of American Sign Language

  Matt Huenerfauth · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper investigates how psycholinguistic insights about the timing and speed of American Sign Language (ASL) can improve computer-generated sign language animations. The author developed two algorithms — a sign-duration algorithm and a pause-insertion algorithm — grounded in…

• A Parametric Approach to Sign Language Synthesis

  Amanda Irving, Richard Foulds · 2005 · Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper describes a parametric approach to synthesizing American Sign Language (ASL) using a commercially available human avatar (UGS Jack) driven by kinematic parameters. The system addresses the fundamental challenge that signed and spoken languages are not mutually…

  Matt Huenerfauth · 2005 · SIGACCESS Accessibility and Computing

  Matt Huenerfauth's 2005 paper describes a research programme to build an English-to-American Sign Language (ASL) machine translation (MT) system that generates animations of a 3D virtual-reality signing character. The author frames the project against a stark literacy gap: most…

• A Multi-Path Architecture for Machine Translation of English Text into American Sign Language Animation

  Matt Huenerfauth · 2004 · Proceedings of the Student Research Workshop at HLT-NAACL 2004

  Huenerfauth's 2004 student-research-workshop paper proposes a 'multi-path' (or 'pyramidal') architecture for English-to-American Sign Language machine translation that unifies the three classical MT paradigms — direct, transfer, and interlingua — into a single system, with each…
