Gesture recognition using neural networks

1. A computer-implemented method for gesture recognition, comprising:

recording an initial point when it is determined that a user presses a finger on a screen comprising a resistive touch panel overlay that can only record a single point at a time;

recording subsequent points and calculating an angle from point to point as the user periodically moves the finger; and

when it is determined that the user's finger is removed from the screen, comparing each of the calculated angles with corresponding ideal angles in order to recognize the gesture;

wherein recognizing the gesture comprises:

iterating through a table to determine two points that are closest to each other when a plurality of points exceeds a threshold number;

calculating a geometric center value of the two points, replacing the first point with the value and deleting the second point; and

repeating the iteration and replacing until the plurality of points is reduced to the threshold number.

2. The computer-implemented method of claim 1 , further comprising:

determining an overall error for each possibility based on the comparing of each of the calculated angles.

3. The computer-implemented method of claim 1 , further comprising:

based on the comparing of each of the calculated angles, selecting the calculated angles with the lowest error to be the correct gesture.

4. The computer implemented method of claim 1 , further comprising:

iterating through a table to determine two points that are furthest away from each other when the plurality of points are below a minimum number of points; and

interpolating a new point between the two points.
