Abstract: This document describes embodiments of a low-latency touch-input device. The low-latency touch-input device receives writing as input to the device and temporarily displays the writing on a physical layer that overlays a touchscreen display of the device. The writing is displayed instantaneously on the physical layer before the touch-input device processes the input. The low-latency touch-input device then processes the input to generate a digital representation of the writing and renders the digital representation of the writing on the touchscreen display to replace the writing displayed on the physical layer.

Abstract: Skinnable touch device grip pattern techniques are described herein. A touch-aware skin may be configured to substantially cover the outer surfaces of a computing device. The touch-aware skin may include a plurality of skin sensors configured to detect interaction with the skin at defined locations. The computing device may include one or more modules operable to obtain input from the plurality of skin sensors and decode the input to determine grips patterns that indicate how the computing device is being held by a user. Various functionality provided by the computing device may be selectively enabled and/or adapted based on a determined grip pattern such that the provided functionality may change to match the grip pattern.

Abstract: Described is a technology by which a computer pointing device (generally a mouse but alternatively a game controller or remote control device) may be worn on the hand and operated without needing to contact a mousing surface. Gyroscopic-based sensors convert the wearer's hand and wrist movements to signals which are sent to a host computing device such as a conventional personal computer, a gaming console, an electronic appliance, and so forth. The data received from the pointing device may be used to move a cursor or the like, and other received data may correspond to left and right mouse clicks, scrolling operations, and so forth. A user-controlled enable switch/sensor selectively activates or deactivates the pointing device so that only intended movements result in data transmission. Gestures may also be sensed and used to trigger defined functions.

Abstract: A data input device for use with a tracking surface having light-scattering properties. The device comprises a coherent light source for projecting a coherent light beam onto the tracking surface to reflect a speckle pattern. A detector having a field of view detects and images the speckle pattern. The detector operates in a tracking mode when the field of view intersects the coherent light beam. The intersection of the coherent light beam and the field of view comprise a detection zone. Relative movement between the coherent light beam and the tracking surface within the detection zone between is detected in the tracking mode, based on the reflected speckle pattern. Relative movement between the coherent light beam and the tracking surface outside the detection zone is not detected. A controller responsive to the detector operates in the tracking mode for correlating the imaged laser speckle pattern to track the relative movement within the detection zone.
