Abstract
A method of analyzing force on a surface is described including providing a pressure-sensitive medium, applying the force to the medium, determining any change in the medium as a result of the applied force, correlating the change in the medium with a pressure value, and analyzing the force value. The pressure-sensitive film may be scanned, each shade or color on the film assigned a pixel value corresponding with pressure values, and the total pixel area values measured to determine pressure characteristics, such as average pressure or total pressure area.
