Force Sensing Touchscreen

摘要

A touchscreen that determines the point of touch and magnitude of a force applied to the touchscreen is disclosed. The force can be perpendicular, parallel, or sloped with respect to the touchscreen surface. The force can also be a plurality of forces simultaneously applied to the touchscreen surface where the centroid and resultant of the plurality of forces are determined. The touchscreen can take the form of various two-dimensional or three-dimensional shapes such as a circle, cube, sphere, cylinder, or the like.

主权项

1. A touchscreen to detect the position of touch and the magnitude of a force applied to a touching panel wherein the force can be parallel, perpendicular, or sloped to the touching panel, and the touchscreen is comprised of;
a touching panel comprised of multiple surfaces attached to each other in three-dimensions; a plurality of sensors each of which is positioned at a corner of a surface of the multiple surfaces to detect the partial force applied to the corner; a microprocessor that receives the data of the partial forces from the plurality of sensors and determines the position of touch and the magnitude of the force.
