Abstract
Embodiments of the present invention disclose a system and method for remote touch detection. According to one embodiment, an infrared light source is projected across a front surface of a display via at least one light emitting device. Furthermore, an infrared signal is transmitted in a direction of the front surface of the display via a remote pointing device. A surface target position is then determined based on measurement data caused by disruption of a portion of the infrared light source of the light emitting device by either the infrared signal or a physical touch from a user.
