“…While not widely used yet [36,37], personal assistive devices [50,54] have the potential to improve real-world accessibility for blind users in a variety of contexts, from providing travel and navigation aids [11,15,50,53] to promoting individual creativity [12,26,32]. Personal assistive devices have also been utilized to support situations such as shopping in order to promote independence.…”

Despite their growing popularity, many public kiosks with touchscreens are inaccessible to blind people. Toucha11y is a working prototype that allows blind users to use existing inaccessible touchscreen kiosks independently and with little effort. Toucha11y consists of a mechanical bot that can be instrumented to an arbitrary touchscreen kiosk by a blind user and a companion app on their smartphone. The bot, once attached to a touchscreen, will recognize its content, retrieve the corresponding information from a database, and render it on the user's smartphone. As a result, a blind person can use the smartphone's built-in accessibility features to access content and make selections. The mechanical bot will detect and activate the corresponding touchscreen interface. We present the system design of Toucha11y along with a series of technical evaluations. Through a user study, we found out that Toucha11y could help blind users operate inaccessible touchscreen devices. CCS CONCEPTS• Human-centered computing → Accessibility systems and tools.

“…But, ultrasound sensors are susceptible to noise, which makes them impractical in busy outdoor environments with multiple static and dynamic obstacles. Similarly, sensor-based walking assists [23] such as WeWalk [40] and GesturePod [35] include gesture-based communication but have a limited range in outdoor environments that restricts their ability to recognize safety hazards [26]. In addition to alerts on proximate obstacles, it is also important to ofer guidance on upcoming path changes and hazards in real time.…”

Fleets of Unmanned Aerial Vehicles (UAVs), also called drones, are becoming commonplace to support diverse applications in logistics and urban safety. These rely on advances in computer vision and Artifcial Intelligence (AI) for autonomous navigation and control, facilitated by onboard sensors and accelerated edge computing devices attached to their base stations. This article examines how drones can be used for social good to enhance the lifestyle of Visually-Impaired People (VIP) through navigational assistance and situation awareness, enabled through visual analytics over drone video streams. We propose Ocularone, a platform for coordinating and managing a heterogeneous UAV feet that ofers drones as buddies to guide users. It uses onboard sensors and edge accelerators, and two-way communication using gestures and audio prompts, to enhance the safety and autonomy of the VIP. We validate our early prototype using Tello nano-drones and Jetson Nano edge accelerators, and present preliminary results for several safety scenarios.
