Changes in Applied Force to Atouchpad during Pointing Tasks
Motoyuki Akamatsu, Ian Scott MacKenzie · Proceedings of the Human Factors and Ergonomics Society Annual Meeting · 2000
We measured the force applied to a touchpad and a mouse during pointing tasks for large and small targets. At the end of selection tasks, changes in the applied force with the touchpad were different from those with a mouse. These differences may be the source of performance differences between the two devices.
