Robert Smith, Brian Nolan · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)
This poster paper evaluates whether adding emotional facial expressions to sign language avatars improves their comprehension and naturalness for Irish Sign Language (ISL) users. Sign languages convey emotion and prosody primarily through non-manual features (NMFs) — facial…

Ted L. Wattenberg · 2005 · Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)
This paper proposes the use of online focus groups as a method for meaningfully including people with disabilities in participatory research, addressing persistent barriers to their involvement in technology studies. The author situates this work within a troubling context:…
