Abstract
A touch sensing system and method uses bending mode sensors and a multiplicity of disparate touch location detection techniques to generate touch location information. A number of bending mode sensors are coupled to a touch sensitive surface. A number of disparate touch location detection techniques are provided, at least one of which uses signals generated by the bending mode sensors. Touch location information is developed using the disparate touch location detection techniques. The touch location information may include the location of a touch to the touch sensitive surface.
