EasyGO: A Field Study of Grocery Store Navigation Application Design for the Visually Impaired

This paper presents a field study of EasyGO, a mobile navigation application designed to help visually impaired individuals navigate grocery stores independently. EasyGO provided both audio and screen interaction methods for adding items, receiving navigation information, and identifying products. This research evaluates EasyGO's usability through interviews and user testing, providing a comprehensive understanding of its real-world application and user experience. Participants preferred a combined screen and audio cue system for navigation, appreciating the proactive nature of audio cues as less distracting and more efficient than periodically checking a screen. Overall, the combination of screen and audio cues emerged as the most favored navigation method, with audio-only being preferred over screen-only delivery.
