Abstract: Examples of methods and systems for providing calibration for eye gesture recognition are described. In some examples, calibration can be executed via a head-mountable device. A method for calibration of a system may account for changes in orientation of the head-mountable device, update recognition of the eye gestures, or increase efficiency of the system, for example. The head-mountable device may be configured to receive signals indicative of eye gestures from an eye gesture-detection system and in response to receiving a second command confirming that the signal is indicative of an eye gesture command, to make adjustments to the eye gesture recognition system and/or the reference signals. The head-mountable device may calibrate an eye gesture recognition system via implicit or explicit calibration, for example.

Abstract: A method is provided for providing scroll-wheel functionality on a touchpad without the touchpad predefining a scroll-wheel. The method includes receiving data corresponding to progressive movement of a touch point on the touchpad, determining from the received data that the progressive movement is substantially elliptical, defining an ellipse around an ellipse center. The method further includes detecting, based on the determined movement, continued angular movement of the touch point around the ellipse center, and registering the continued angular movement as one or more scroll events in the computing system.

Abstract: A method is provided for determining a word input by a gesture stroke on a virtual keyboard. The method includes receiving data representing the gesture stroke, analyzing the data to identify a set of dwell points in the gesture stroke, generating a simplified stroke defining a polyline having vertices corresponding with the dwell points of the identified set. The method further includes comparing the simplified stroke polyline with a plurality of predefined polylines each representing a respective word, to determine a closest matching polyline. The computing system outputs the word represented by the closest matching polyline.

Abstract: A method is provided for managing phrase completion suggestions in response to text input. The method includes receiving text entered into the computing system, and identifying a first plurality of phrases that each begins with the received text and that each includes a respective phrase segment immediately following the received text. The method further includes displaying a first list of the respective phrase segments of the identified first plurality of phrases without displaying the received text, and receiving input defining a selection of one of the respective phrase segments of the displayed first list.

Abstract: A computing device includes a trackpad, which includes a touch-sensitive surface having a touch-detectable pattern. The touch-detectable pattern includes a first feature, and a second feature having first and second side features. The first and second side features start in proximity of the first feature and are positioned on opposite sides of the first feature.

Abstract: The present invention discloses systems and methods for the measurement of surfaces. More particularly, the present invention discloses a portable, hand-held, non-contact surface measuring system comprising an image capturing element, at least four projectable reference elements positioned parallel to one another at known locations around the image capturing element, a processing unit, and a user interface. The present invention further discloses a method for the non-contact surface measurement comprising projecting at least four references onto a target surface, capturing an image of the targeted surface and the projected references with the image transferring device, transferring the image to a processing unit, processing the image using triangulation-based computer vision techniques to correct for skew and to obtain surface measurement data, transferring the data to the user interface, modifying the data with the user interface.
