Abstract:
We investigate the design of a user-friendly natural user interface for the deaf and hard of hearing (DHH). Voice-based conversational user interfaces (CUIs), such as Amazon Alexa and Google Assistant, are becoming increasingly popular among consumers. DHH users may not be aware of notifications from CUIs, may not be able to obtain response information, and may have difficulty waking up the CUIs. In this study, we designed a system that adds luminous notifications and sign language to the CUI and conducted Wizard of Oz experiments to investigate whether the system can provide an optimal user experience for DHH users. The results suggest that luminous notifications improve the usability and make notifications easier. After assessing the necessity of sign language/text display, we found that people with longer sign language histories tend to use sign language, and all people require the use of a text display. The percentage of DHH users who gazed at the system before entering commands into the system (93.4%) also suggests that gazing can be an effective way to wake up the system. Our findings provide guidance for future CUI designs to improve the accessibility for DHH users.
