    摘要: 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.

    摘要: 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.

    摘要: Documents stored in a database are searched for relevance to contextual information, instead of (or in addition to) similar text. Each stored document is indexed in term of meta-information specifying contextual information about the document. Current contextual information is acquired, either from the user or the current computational or physical environment, and this “meta-information” is used as the basis for identifying stored documents of possible relevance.

    摘要: Implementations are described of a waveguide apparatus including a proximal end, a distal end, a front surface and a back surface, the back surface being spaced apart from the front surface. A display input region is positioned at or near the proximal end, an ambient input region is positioned on the front surface near the distal end and an output region is positioned on the back surface near the distal end. One or more optical elements is positioned in or adjacent to the waveguide to direct display light from the display input region to the output region and to direct ambient light from the ambient input region to the output region, and an switchable mirror layer is positioned in or on the waveguide to selectively control the amount of ambient light that is directed to the output region. Other embodiments are disclosed and claimed.
