    • 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.
    • 本发明的实施例公开了一种用于远程触摸检测的系统和方法。 根据一个实施例,红外光源经由至少一个发光器件横跨显示器的前表面投影。 此外,通过远程指示装置在显示器的前表面的方向上发送红外信号。 然后基于由来自用户的红外信号或物理触摸而使发光器件的红外光源的一部分的中断而引起的测量数据来确定表面目标位置。
