Trackball Ergonomic Mouse

Mouse

This trackball ergonomic mouse introduces a new interaction paradigm that transforms human–computer relationships. By replacing repetitive wrist motion with a thumb-operated trackball and static vertical grip, it enables cursor control without moving the device. This "static wrist + dynamic fingertip" logic reduces fatigue and eliminates desktop space dependency. With its spatial efficiency, biomechanical integrity, and structural precision, it serves professionals in design, programming, and medical fields requiring long-term digital engagement.
