Patent ID: 8902198

Claim:
A computer-implemented method of enabling input to a computing device, comprising: activating a gesture input mode on the computing device; capturing image information using a camera of the computing device; analyzing the image information, using a processor of the computing device, to determine relative positions of a fingertip and a thumb on a hand of a user respect to the computing device, the fingertip and the thumb being at least a determined distance from the computing device; determining whether the fingertip and the thumb contacted each other; and in response to determining that the fingertip and the thumb contacted each other: monitoring a pattern of motion of the fingertip and the thumb with respect to the computing device; displaying a graphical element on a display screen corresponding to the pattern of motion of the fingertip and the thumb with respect to content displayed on the display screen; analyzing, by the processor, the pattern of motion using at least one pattern recognition algorithm; and providing input to the computing device corresponding to a stored pattern determined to match the pattern of motion with at least a minimum level of confidence.
