Abstract: A method includes: detecting, at a computing device coupled to an image sensor, an input request; in response to detecting the input request, capturing a reference image via the image sensor, the reference image containing a virtual keypad having a set of virtual keys; detecting, in the reference image, the set of virtual keys; capturing, via the image sensor, a key-press image of the virtual keypad; detecting, in the key-press image, a subset of the virtual keys; comparing the set of virtual keys and the subset of virtual keys to identify a key-press obscuring one of the virtual keys; and returning input data corresponding to the obscured virtual key.
