Abstract
A force/displacement touch device, this invention employs a base-planeand flexible mounting material to suspend, or 'float,' a non-rigidly mounted touch-plane, and uses sensors at each mounting pointto measure Z-axis deflection of the floating touch-plane. The system adapts existing planes in typical LCD assemblies to implement touch screens. This floating touch detection system provides an accurate, sensitive, compact and low-cost solution. It mitigates XY friction to improve detection of Z-forces. This approach provides latitude in locating sensors, allows for additional mid-plane sensors, enables greater accuracy and resolution, and adds features such as 'multi-touch' sensitivity. This touch system is defined as a unique and novel 'floating' co-planar assembly of a touch-planeto a base-plane, which uses a flexible materialor medium to define a consistent resting air gap, and then senses and measures any deflection from the co-planar resting position, using any among a broad variety of sensor types.
