Techniques For Using Gesture Recognition To Effectuate Character Selection
First Claim
1. A method, comprising:
- receiving with a computing device digital data representing a string of images, the images representing at least part of a user;
processing the data using software to detect therefrom a string of gestures of the user, each gesture represented as a vector;
mapping the vectors to a string of phonetic elements; and
identifying one or more words in a written language corresponding to a string of the phonetic elements.

Abstract
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.

16. An apparatus comprising instructions stored on non-transitory machine-readable media, the instructions when executed to cause at least one processor to:
-
receive data representing a string of images, the images representing at least part of a user; process the data to detect therefrom a string of gestures, each gesture represented by a vector; map the vectors to a string of phonetic elements; and automatically identify words in a written language corresponding to a string of the phonetic elements.

17. An apparatus, comprising:
-
an input device to receive data representing a string of images, the string of images representing at least part of a user; and at least one processor to process the data to detect a string of gestures of the user from the images, each gesture corresponding to a vector, map the vectors to a string of phonetic elements, and automatically identify words in a written language corresponding to a string of the phonetic elements. - View Dependent Claims (18, 19, 20)
