Touchscreen devices, designed with an assumed range of user abilities and interaction patterns, often present challenges for individuals with diverse abilities to operate independently. Prior efforts to improve accessibility through tools or algorithms necessitated alterations to touchscreen hardware or software, making them inapplicable for the large number of existing legacy devices. This disclosure introduces a hardware interaction proxy that performs physical interactions on behalf of users while allowing them to continue utilizing accessible interfaces, such as screen readers and assistive touch on smartphones, for interface exploration and command input. The proxy maintains an interface model for accurate target localization and utilizes exchangeable actuators for physical actuation across a variety of device types, effectively reducing user workload and minimizing the risk of mistouch. Evaluations reveal that this approach lowers the mistouch rate and empowers visually and motor impaired users to interact with otherwise inaccessible physical touchscreens more effectively.

A system providing persistent display of prioritized participants with shared content. In a virtual meeting, a system can automatically and adaptively place a specific attendee's video based on the attendee's role and shared content having a specific data type. For example, a user can have accessibility settings that indicates a need for assistance. The system can automatically display a persistent display of a video stream of that user's assistant in a user interface. When content is shared, the system analyzes a rendering of the content to identify regions where the shared content is not displayed. The system then dynamically configures the user interface so that the persistent display of the video stream of the user's assistant is located in a region where the shared content is not displayed. Such features enable the user to have a consistent view of an assistant during the display of shared content.
