Abstract
An optical touch pad that includes a multilayer waveguide optically coupled to at least one electromagnetic radiation detector. Based on electromagnetic radiation directed from an object to the detector by the multilayer waveguide, information related to an object proximate to (e.g., hovering above) and/or in contact with the optical touch pad may be determined. For example, the information related to the object may include position information, object-type information, and/or other information related to the object.
