8. The computer-implemented method of claim 7 , wherein the at least one gesture associated with the user is one of a plurality of gestures stored on the computing device.
7. A computer-implemented method, comprising: under control of one or more computing devices including executable instructions, acquiring image information from at least one image captured using at least one image sensor of a computing device, the image information being stored for a duration of time on a rolling basis; analyzing the image information to detect a hand gesture performed by a user; determining, in the image information, movement of one or more fingers, the movement corresponding to a first portion of a candidate hand gesture; analyzing the image information stored for the duration of time to detect a second portion of the candidate hand gesture; comparing the first portion of the candidate hand gesture and the second portion of the candidate hand gesture to at least one gesture associated with the user, the second portion of the candidate hand gesture having been performed before the first portion; and providing an input to an application executing on the computing device in response to the first portion of the candidate hand gesture and the second portion of the candidate hand gesture being determined to correspond to the at least one gesture associated with the user, the at least one gesture associated with the user being specific to the user for providing the input to the application.
