Abstract: Computing devices can comprise a processor and an imaging device. The processor can be configured to support both a mode where gestures are recognized and one or more other modes during which the computing device operates but does not recognize some or all available gestures. The processor can determine whether a gesture recognition mode is activated, use image data from the imaging device to identify a pattern of movement of an object in the space, and execute a command corresponding to the identified pattern of movement if the gesture recognition mode is activated. The processor can also be configured to enter or exit the gesture recognition mode based on various input events.

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. During a first sampling iteration, a range of pixels can be identified from a location of a feature of the object, with the range used in sampling from the at least one imaging device during a second iteration based on the data sampled during the first iteration.

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. An interactive volume can be defined and adjusted so that the same movement at different locations within the volume may result in different corresponding movement of a cursor or other interpretations of input.

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, including 2-dimensional and 3-dimensional movements with or without touch.

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.
