摘要： A computing device and/or application executing on the device can utilize fingertip tracking using a camera. However, when the fingertip is in a dead zone (an area that is not viewable by the camera), the fingertip tracking cannot function properly. Nevertheless, the position of the fingertip, when in the dead zone, can still be estimated. An image of a user's hand can be captured by at least one camera. A portion of a pointing finger can be detected in the captured image. An orientation of the portion of the pointing finger can be determined. One or more joint lines of the pointing finger can be identified. Based on data about a slant and/or a bend of the pointing finger obtained using information relating to the identified joint line(s), and/or on data obtained via calibration and/or historic/current usage, the position of the fingertip, when in the dead zone, can be approximated.

摘要： A user can emulate touch screen events with motions and gestures that the user performs at a distance from a computing device. A user can utilize specific gestures, such as a pinch gesture, to designate portions of motion that are to be interpreted as input, to differentiate from other portions of the motion. A user can then perform actions such as text input by performing motions with the pinch gesture that correspond to words or other selections recognized by a text input program. A camera-based detection approach can be used to recognize the location of features performing the motions and gestures, such as a hand, finger, and/or thumb of the user.
