Techniques For Using Gesture Recognition To Effectuate Character Selection

This disclosure provides a pose- or gesture-based recognition system that processes images of the human hand, downconverts degrees of freedom of the human hand to lower-dimensional space, and then maps the downconverted space to a character set. In one embodiment, the system is implemented in a smart phone or as a computer-input device that uses a virtual keyboard. As the user moves his or her hand, the smart phone or computer provides simulated vocal feedback, permitting the user to adjust hand position or motion to arrive at any desired character; this is particularly useful for embodiments which use a phonetic character set. Software that performs character selection can be implemented in a manner that is language/region agnostic, with a contextual dictionary being used to interpret a phonetic character set according to a specific language or region.
