Abstract: Embodiments of the invention generally provide an input device that includes a zero-dimensional button that detects whether an input object is proximate to a sensing region. However, different input objects may provide similar responses which may prevent the input device from accurately determining whether the user actually intended to activate the button.

Abstract: A set of optical fibers can be used to enable touch input for a computing device. One or more light sources, such as infrared (IR) light emitting diodes (LEDs), can direct radiation into one or more fibers that propagates down the fibers and is detected by one or more sensors. If a user places a finger at a position where a portion of a fiber is exposed, a portion of the light propagating down the fiber will not undergo total internal reflection (TIR) and instead will be transmitted out of the fiber, causing a reduction in the amount of light received from that fiber to one of the sensors. By monitoring losses for the fibers and knowing the area at which each fiber is exposed, locations at which the losses occur can be determined. These locations can correspond to various types of user input.
