Abstract:
A hybrid optical-physical touch screen is provided herein. The touch screen includes: an electronic panel display; one or more optical sensors coupled to the electronic panel display and configured to determine, a spatial location of a physical object on an X-Y plane near the electronic panel display; a plurality of physical touch sensors coupled to the electronic panel display and configured to determine, a physical touch event between the physical object and the electronic panel display; and a processor configured to compare the determined spatial location of the physical object with the determined physical touch event between the physical object and the display at a same time, and determine, based on predefined parameters, whether an intentional physical touch event between the physical object and the electronic panel display has occurred.
