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. 

Texting relies on screen-centric prompts designed for sighted users, still posing significant barriers to people who are blind and visually impaired (BVI). Can we re-imagine texting untethered from a visual display? In an interview study, 20 BVI adults shared situations surrounding their texting practices, recurrent topics of conversations, and challenges. Informed by these insights, we introduce TextFlow : a mixed-initiative context-aware system that generates entirely auditory message options relevant to the users’ location, activity, and time of the day. Users can browse and select suggested aural messages using finger-taps supported by an off-the-shelf finger-worn device, without having to hold or attend to a mobile screen. In an evaluative study, 10 BVI participants successfully interacted with TextFlow to browse and send messages in screen-free mode. The experiential response of the users shed light on the importance of bypassing the phone and accessing rapidly controllable messages at their fingertips while preserving privacy and accuracy with respect to speech or screen-based input. We discuss how non-visual access to proactive, contextual messaging can support the blind in a variety of daily scenarios.
