Abstract: An interactive display system that may be implemented to provide an electronic whiteboard that enables users to input information to the system by engaging a display with one or more objects. The system may present an image via the display that reflects the inputs received from the user. For example, the display may be dynamically updated to mimic inputs made to a whiteboard by the user via one or more pens and/or an eraser. The interactive display system may implement an underlayer embedded within the display to guide electromagnetic radiation that emanates from an object engaged with the display to one or more detectors by total internal reflection. Due at least in part to the efficiency of the underlayer in guiding the electromagnetic radiation to the detectors, the interactive display system may enhance the speed and/or accuracy of the interpretation of the inputs made by the user.
