Abstract

The evaluation discussed in this paper explores the role that underlying facial expressions might have regarding understandability in sign language avatars. Focusing specifically on Irish Sign Language (ISL), we examine the Deaf community’s appetite for sign language avatars. The work presented explores the following hypothesis: Augmenting an existing avatar with various combinations of the 7 widely accepted universal emotions identified by Ekman [1] to achieve underlying facial expressions, will make that avatar more human-like and consequently improve usability and understandability for the ISL user. Using human evaluation methods [2] we compare an augmented set of avatar utterances against a baseline set, focusing on two key areas: comprehension and naturalness of facial configuration. We outline our approach to the evaluation including our choice of ISL participants, interview environment, and evaluation methodology.
