Abstract: A user can make a symbol with their hand, or other such gesture, at a distance from a computing device that can be captured by at least one imaging element of the device. The captured information can be analyzed to attempt to determine the location of distinguishing features of the symbol in the image information. The image information is then compared to hand gesture information stored in, for example, a library of hand gestures for the user. Upon identifying a match, an input to an application executing on the computing device is provided when the image information contains information matching at least one hand gesture with at least a minimum level of certainty. The hand gesture could include a single “static” gesture, such as a specific letter in sign language, for example, or include two or more “static” gestures. The gesture could also include motion, such as hand movement.

Abstract: Data on a first computing device can be represented by a graphical object displayed on a screen of the first device. A user can initiate an “attach event” (e.g., a pinching gesture with respect to the object) to enable the object (e.g., the data represented by the object) to be associated and/or virtually attached to him/her. One or more cameras can view/track the user's hand/finger movement(s). Based on the viewed/tracked movement(s), the object representing the data can be moved on a screen of the first device to correspond to the movement of the user's hand/finger. The object can also be moved to a position on a screen of a second computing device when the user moves his/her hand/finger to an area corresponding to the position. A user initiated “release event” (e.g., an unpinching gesture) can end the association and enable the data to be shared with the second device.

Abstract: 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.
