GESTURE RECOGNITION USING NEURAL NETWORKS
First Claim
Patent Images
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; and
repeating the iteration and replacing until the plurality of points is reduced to the threshold number.

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.

8. 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 a user presses a finger on a screen; calculate 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, compare each of the calculated angles with corresponding ideal angles in order to recognize a 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 repeat the iteration and replacing until the plurality of points is reduced to the threshold number. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program, embodied on a non-transitory computer-readable medium, the computer program, when executed, configured to cause a processor to:
-
record an initial point when a user presses a finger on a screen; calculate 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, compare each of the calculated angles with corresponding ideal angles in order to recognize a gesture; 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 repeat the iteration and replacing until the plurality of points is reduced to the threshold number. - View Dependent Claims (16, 17, 18, 19, 20)
