USER INTERFACE FOR TEXT INPUT ON THREE DIMENSIONAL INTERFACE

摘要

A three dimensional data input system includes a space sensor that can input commands and text based upon user gestures within a three dimensional space. The three dimensional space can include a virtual keyboard and the system identifies words input as a set of points input by a user on the virtual keyboard. The intended word is identified by determining an origin and points associated with letters on a log polar coordinate system. The log distances and angles of the points are then compared to log distances and angles for known words stored in a computer memory. The known word having the log distances and angles that most closely match the input points is identified as the intended word.

主权项

1. A text input method comprising:
providing a sensor for detecting positions of portions of the body in a three dimensional space, the sensor transmitting position information to a processor; detecting by the sensor, a first sequence of input locations of portions of the body in the three dimensional space associated with an intended word; defining a virtual keyboard plane by a processor, based upon a first three or more inputs of the sequence of input locations; identifying by the processor, a word stored in a dictionary that most closely matches the relative positions and the sequence of input locations on the virtual keyboard in the three dimensional space; and inputting by the processor, the word to a sequence of input text.
