Developing Miniature Force-Sensing Technologies for Measuring the Forces Applied to a Computer Mouse

Force-sensing technologies, 1.4 − 2.5 mm thick, were developed to measure the forces applied to the button and sides of a computer mouse. A force-sensing computer mouse was developed, built and tested for force measurement accuracy. The force-sensing technology could accurately measure the forces applied to the sides of a mouse and identify the location of force application. The force-sensing technology also accurately measured the forces applied to the mouse button with slight measurement errors at low forces. The force-sensing technologies developed in this study were made from commercially available materials, were relatively low cost and will be readily exportable to different mouse designs. These force-sensing technologies should assist manufacturers, designers and researchers in better understanding how various hand held devices and tools are gripped and operated.
