1. A computer-implemented method, comprising: acquiring, by a computing device, image data; analyzing a first subset of the image data acquired over a first period to identify a gesture; determining a first path corresponding to movement of a representation of one or more fingers in the first subset of the image data; comparing the first path to a gesture library; analyzing a second subset of the image data acquired over a second period to identify the gesture in response to being unable to identify a first path matching gesture; determining a second path corresponding to movement of the representation of one or more fingers in the second subset of the image data; determining, from the first path and the second path, a combined path corresponding to the movement of the representation of the one or more fingers ; determining a combined path matching gesture by comparing the combined path to the gesture library; and sending an input to an application executing on the computing device.
