Ergonomic personal computer mouse

摘要

The PC mouse profile is raised on the thumb side (6) and has a ball shape (1) in the centre on an inclined plane to support the palm. The mouse buttons, wheels or balls (3) are fitted on the raised profile at an angle of 10 to 60 degrees. The outer edge of the operator's hand is supported by a raised edge (2) of adjustable width and angle. The input roller ball (4) on the under side is offset from the centre to one side. Support rollers (5) are fitted on all four corners. The angles of the mouse keys, wheels or balls can be adjusted individually.
