发明名称 COMPUTER VISION-BASED MULTI-TOUCH SENSING USING INFRARED LASERS
摘要 The claimed subject matter provides a system and/or a method that facilitates detecting a plurality of inputs simultaneously. A laser component can be coupled to a line generating (LG) optic that can create a laser line from an infrared (IR) laser spot, wherein the laser component and line generating (LG) optic emit a plane of IR light. A camera device can capture a portion of imagery within an area covered by the plane of light. The camera device can be coupled to an IR-pass filter that can block visible light and pass IR light in order to detect a break in the emitted plane of IR light. An image processing component can ascertain a location of the break within the area covered by the emitted plane of IR light.
