Abstract: Object detection techniques for use in conjunction with optical sensors is described. In one or more implementations, a plurality of inputs are received, each of the inputs being received from a respective one of a plurality of optical sensors. Each of the plurality of inputs are classified using machine learning as to whether the inputs are indicative of detection of an object by a respective said optical sensor.

Abstract: One or more techniques and/or systems are provided for providing a control user interface (UI) element. The control UI element, associated with a continuous variable, may be displayed, such as in association with a user interface (e.g., the control UI element may correspond to a view rotation variable of a map interface). The control UI element may comprise a current state indicator element configured to display a current state of the continuous variable (e.g., a compass displaying a current heading associated with the view rotation variable). The control UI element may be populated with one or more expanded control elements associated with various aspects of the continuous variable (e.g., a first expanded control element may be used to modify a right rotation aspect of the view rotation variable and a second expanded control element may be used to modify a left rotation aspect of the view rotation variable).

Abstract: Grip-based device adaptations are described in which a touch-aware skin of a device is employed to adapt device behavior in various ways. The touch-aware skin may include a plurality of sensors from which a device may obtain input and decode the input to determine grip characteristics indicative of a user's grip. On-screen keyboards and other input elements may then be configured and located in a user interface according to a determined grip. In at least some embodiments, a gesture defined to facilitate selective launch of on-screen input element may be recognized and used in conjunction with grip characteristics to launch the on-screen input element in dependence upon grip. Additionally, touch and gesture recognition parameters may be adjusted according to a determined grip to reduce misrecognition.

Abstract: Menu configuration techniques are described. In one or more implementations, a user's orientation is determined with respect to the computing device based at least in part on a part of the user that contacts the computing device and at least one other part of a user that does not contact the computing device. A menu is displayed having an orientation on a display device of the computing device based at least in part on the determined user's orientation with respect to the computing device.

Abstract: Menu gesture techniques are described. In one or more implementations, a menu is displayed on a display device of a computing device. The menu has a plurality of selectable items along with a visual indication that is configured to follow a touch input across the display device and indicate that each of the plurality of selectable items is selectable via a drag gesture. One or more inputs are recognized by the computing device as movement of the touch input across the display device to identify the drag gesture to select at least one of the plurality of selectable items in the menu.
