Abstract

A computing device, such as a desktop, laptop, tablet computer, a mobile device, or a computing device integrated into another device (e.g., an entertainment device for gaming, a television, an appliance, kiosk, vehicle, tool, etc.) is configured to determine user input commands from the location and/or movement of one or more objects in a space. The object(s) can be imaged using one or more optical sensors and the resulting position data can be interpreted in any number of ways to determine a command. Signal conditioning logic (or a programmable CPU) can be used to facilitate detection by performing at least some image processing in hardware before the image is provided by the imaging device, such as by a hardware-implemented ambient subtraction, infinite impulse response (IIR) or finite impulse response (FIR) filtering, background-tracker-based touch detection, or the like.
