Embodiment

[0035] Such as figure 1 As shown, a gesture control method for adaptive adjustment of a mapping relationship includes the following steps:

[0036] A. Start up;

[0037] B. The user extends the control hand in a natural state and hovers in a comfortable position;

[0038] C. The camera recognizes important parts such as gestures, face, and torso;

[0039] D. According to the data obtained in step C, determine the position of the palm of the control hand in the initial state as the center reference point of the hand operation distance;

[0040] E. According to the central reference point determined in step D, combined with the recognition data of important parts such as the face and torso, determine the width L of the face, and the background control system determines the distance gradient value a that triggers the change of the mapping parameters 1 L.a 2 L.a 3 L, where a x L(x=0,1,2,3...) is the length constant;

[0041] F. The user moves the control hand, and the contr...

Abstract

The invention discloses a gesture control method capable of self-adaptively adjusting the mapping relation, which includes the following steps: (1) a computer is started up; (2) a user extends and stops a controlling hand in the air; (3) gestures, the face and the like are identified by a camera; (4) a central reference point is determined; (5) the face width L is determined by a system according to identification data, so that a plurality of distance gradient values triggering the change of mapping parameters are determined; (6) the controlling hand is moved by the user, and an absolute distance S is determined by the system; (7) the S is compared with each gradient value, and a corresponding interval is determined; (8) the mapping relation corresponding to one specific gradient value of the interval is called; (9) step 6, step 7 and step 8 are repeated, and according to the position of the hand, the mapping relation is adjusted in real time; (10) the system samples and records the mapping parameters at regular intervals and finely adjusts the gradient value and the mapping relation according to the sampling statistic, improving the mapping parameters. The method has the advantage that the method can improve the experience of users in non-contact gesture operation.

Description

technical field [0001] The invention relates to a human-computer interaction technology, in particular to a gesture control method for adaptive adjustment of a mapping relationship. Background technique [0002] With the continuous development of technology, modern society is becoming more and more intelligent and humanized. Gesture control, voice control, face recognition and other non-contact operation methods have brought great convenience to people's life and work. At this stage, the control methods of human-computer interaction are mainly mouse, keyboard, remote control and touch screen, etc. There are also more cutting-edge control methods, such as gesture control and voice control. [0003] At present, in the gesture control method, the patent application number is PCT / CN2012 / 075798, which provides a non-contact gesture control method and device, and performs non-contact operation through gestures to realize the long-distance operation needs of the target. [0004] ...
