Abstract
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.
Claims15
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.

An apparatus, comprising:
- a processor;
- and
- memory configured to store an application,
- wherein the application, when executed, is configured to cause the processor to:
- record 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;
- record subsequent points and calculate 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, compare each of the calculated angles with corresponding ideal angles in order to recognize the gesture;
- wherein the processor is further configured to:
- iterate through a table to determine two points that are closest to each other when a plurality of points exceeds a threshold number;
- calculate a geometric center value of the two points, replacing the first point with the value and deleting the second point;
- and
