This research introduces “Countmarks,” an ergonomic interaction method for smart glasses using multi-finger gestures on a smartphone. It offers a faster, more accurate, and private alternative to controllers, voice commands, and mid-air gestures. The system improves usability, accessibility, and safety, particularly in real-world contexts like walking or driving.

his research develops a classification system for wheelchair navigation based on surface difficulty, inspired by ski trail ratings. By measuring vibration and effort across urban environments, it aims to provide users with actionable information to support safer route choices, reduce injury risk, and improve independence and accessibility in everyday mobility.
