Despite growing interest in accessible texting for people who are blind and visually impaired (BVI), little is known about the practice of texting when on the move, and especially while using assistive technologies. To address this gap, we conducted an interview-based study with 20 BVIs who text while travelling. Our findings revealed that participants engage in text outside their home in four recurrent situations: walking to a destination, waiting for public transportation, riding in a vehicle, or approaching a point of interest. Moreover, to safely send a text, participants express the need for receiving a range of information about their surroundings, including the distance to destination, upcoming obstacles, traffic jams, and weather conditions. Based on these findings, we examine three modes of situational feedback cues to integrate with messaging applications: text-based, sound effects, and tactile. Our work discusses design directions to enhance the texting experience in nomadic contexts for people who are blind and visually impaired.
