AidServer: Design and Research of a Communication Accessibility Service System for Hearing Impaired Servers in Silent Restaurants

This paper introduces a communication accessibility service system called AidServer, aimed at enhancing communication between deaf service staff and deaf customers in silent restaurants. Due to their limited communication abilities, deaf individuals often face challenges when seeking suitable employmen [1–4]. However, with the emergence of silent restaurants [5] deaf individuals have found new employment opportunities. AidServer comprises three components: a software application for deaf service staff, a service call button, and a wearable voice amplifier. We conducted laboratory system usability tests and real restaurant scenario applications to evaluate the effectiveness of the system. The results demonstrate that the AidServer system significantly improves communication efficiency between deaf service staff and deaf customers in real restaurant operations. The proposed system can increase the social participation and labor capabilities of deaf individuals, making it a valuable contribution to the field of communication accessibility.
