Collaborative Team Learning Approach for Web Development

This paper presents a collaborative team learning model for integrating student learning in a graduate IS course and a graduate HCI course. Through coordinated project schedules of partnering teams, an emphasis on social interaction, and the use of collaborative technologies, students expanded their experience in developing Internet commerce Web sites. For the HCI teams, they learned realistic consulting experience. For the IS teams, HCI support led to high quality Web site prototypes. This paper reviews the motivation, approaches, evaluation methods, findings, and implications of this innovative teaching method

Synthetic Corpora: A Synergy of Linguistics and Computer Animation

Synthetic corpora enable the creation of computer-generated animations depicting sign language and are the complement of corpora containing videotaped exemplars. Any design for a synthetic corpus needs to accommodate linguistic processes as well as support the generation of believable, acceptable synthesized utterances. This paper explores one possibility for representing linguistic and extralinguistic processes that involve the face and reports on the outcomes of a user test evaluating the clarity of utterances synthesized by this approach

Generating Co-occurring Facial Nonmanual Signals in Synthesized American Sign Language

Translating between English and American Sign Language (ASL) requires an avatar to display synthesized ASL. Essential to the language are nonmanual signals that appear on the face. In the past, these have posed a difficult challenge for signing avatars. Previous systems were hampered by an inability to portray simultaneously-occurring nonmanual signals on the face. This paper presents a method designed for supporting co-occurring nonmanual signals in ASL. Animations produced by the new system were tested with 40 members of the Deaf community in the United States. Participants identified all of the nonmanual signals even when they co-occurred. Co-occurring question nonmanuals and affect information were distinguishable, which is particularly striking because the two processes move an avatar’s brows in a competing manner. This breakthrough brings the state of the art one step closer to the goal of an automatic English-to-ASL translator.

Linguistics As Structure In Computer Animation: Toward A More Effective Synthesis Of Brow Motion In American Sign Language

Computer-generated three-dimensional animation holds great promise for synthesizing utterances in American Sign Language (ASL) that are not only grammatical, but well tolerated by members of the Deaf community. Unfortunately, animation poses several challenges stemming from the necessity of grappling with massive amounts of data. However, the linguistics of ASL can aid in surmounting the challenge by providing structure and rules for organizing animation data. An exploration of the linguistic and extra linguistic behavior of the brows from an animator’s viewpoint yields a new approach for synthesizing nonmanuals that differs from the conventional animation of anatomy and instead offers a different approach for animating the effects of interacting levels of linguistic function. Results of formal testing with Deaf users have indicated that this is a promising approach

SignQUOTE: A Remote Testing Facility for Eliciting Signed Qualitative Feedback

Sign synthesis is still an evolving technology and improving it requires the elicitation of qualitative feedback from users. Current options for acquiring qualitative feedback are limited. Face-toface tests conducted in sign language are expensive. On the other hand, remote tests do not use the preferred language of the test participants. A new tool, SignQUOTE, (Signed Qualitative Usability Online Testing Environment) is a configurable, cross platform remote testing system based entirely on sign language. It includes an innovative method for capturing qualitative feedback in sign language via webcam. In a comparison study, participants viewed animations of American Sign Language and gave suggestions for improvement. The authors conducted a study using SignQUOTE that presented stimuli identical to those used in a previously-conducted face-to-face study. When comparing the two approaches, the authors found results that are consistent with previous comparison studies of remote and face-to-face testing. SignQUOTE comes with a Test Designer that allows researchers to customize tests. The software is available as open source.
