GESTURE RECOGNITION USING NEURAL NETWORKS

摘要

An apparatus, method, and a computer program is provided for gesture recognition using neural networks. An initial point is recorded when a user presses a finger on a screen. Subsequent points are recorded and an angle is calculated from point to point as the user periodically moves the finger. A set of the calculated angles are compared with an ideal angle in order to recognize the gesture.

主权项

1. A computer-implemented method, comprising:
recording an initial point when a user presses a finger on a screen; calculating an angle from the initial point to one or more other points as the user 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 a 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; andrepeating the iteration and replacing until the plurality of points is reduced to the threshold number.
