Human-centered design for a sign language learning application.

An animated sign language dictionary is a valuable resource for caregivers learning to communicate with residents who use sign language. This case study reports on the development of such a tool using the human-centered design methodology. Through interviews and observations with key stakeholders, we realized that our efforts could benefit a broader population that included the residents themselves. The result of this thoughtful approach is an application that is accessible across multiple platforms and features interaction modalities to accommodate the needs of various user groups.
