Benefits of technology

The motion detection method described in this patent can accurately identify and classify complex movements by analyzing the angle at which a reflective body moves and the direction in which it moves. This helps to minimize errors when using electronic devices that rely on motion detection, making them more reliable and convenient to use.

Problems solved by technology

It is generally very inaccurate to use a value of a reflection degree from a simple optical system for obtaining an absolute value of a distance.
However, because it is difficult to clearly classify and recognize a complex or unclear gesture or motion in the optical gesture recognizing method according to the related art, reliability of a motion identifying function deteriorates.
That is, a specific motion may not be accurately recognized such that a reaction corresponding to the motion may not occur or may be recognized as another motion, causing an intended reaction.
Accordingly, operation errors of electronic devices based on recognition of a motion may frequently occur, and a user may feel inconvenient when using the electronic device or have distrust against a motion identification function.

Abstract

A motion recognition method includes: a light detecting step of detecting light reflected by the reflective body to measure a luminous intensity of the light by the light receiving element; a first coordinate setting step of setting a planar coordinate (X1, Y1) of the reflective body; a second coordinate setting step of setting a planar coordinate (X2, Y2) of the reflective body; and a direction determining step of obtaining an angle (θ) between a line segment connecting the origin and the planar coordinate (X1, Y1) in the first position and a line segment connecting the planar coordinate (X1, Y1) in the first position and the planar coordinate (X2, Y2) in the second position and determining that the reflective body moves in a direction passing through a ½ point of the angle (θ) in the first position by the data processing unit.

Description

TECHNICAL FIELD [0001]The present invention relates to a motion recognition method, and more particularly to a motion recognition method in which, in order to execute various functions of an electronic device according to a motion of a reflective body such as a hand of a user, a light emitting element projects light and a light receiving element detects light reflected by the reflective body to determine an movement direction of the reflective body.BACKGROUND ART [0002]In general, recognition of a motion is based on a step of repeatedly measuring reflection degrees of a reflective body, a step of identifying a change in a proximate location of the reflective body over time by comparing the measured reflection degrees, and a step of analyzing a change at the proximate location of the reflective body with a motion associated with a specific gesture which can be analyzed as a movement of the user or a motion vector of the reflective body, in order to determine a proximate location of t...
