This research investigates smart office chairs that monitor posture and provide real-time feedback to reduce pain and improve ergonomics. By comparing different feedback methods, the study evaluates whether timely reminders can effectively change behavior. The goal is to enhance workplace health while maintaining productivity in increasingly sedentary environments.

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.
