Differences in movement microstructure of the mouse and the finger-controlled isometric joystick
Anant Kartik Mithal, Sarah A. Douglas · 1996
This paper describes a study comparing the movement characteristics of the mouse and the velocity-control isometric joystick.These characteristics are called the microstructure of movement.The comparison found random variations in the velocity of the isometric joystick that make it hard to control.The study shows that the microstructure of movement can explain differences in performance among devices.
