Gesture control device and gesture recognition method

Abstract

The invention provides a gesture control device and a gesture recognition method. The gesture control device comprises a computation terminal and a plurality of sensors, wherein the computation terminal is used for carrying out offline natural gesture modeling and online gesture recognition; the sensors are respectively arranged at the small arm, big arm and trunk of a tested object so as to correspondingly acquire the gesture coordinates of the small arm, big arm and trunk; and the sensors are connected with the computation terminal in a communication manner. In the online gesture recognition process, the computation terminal carries out computation processing on the basis of data acquired by the sensors, and the actual state, obtained through the computation processing, of the tested object is automatically compared with a gesture model obtained in the offline natural gesture modeling process of the computation terminal to complete the gesture recognition of the tested object. In the gesture control device, the computation terminal can process the repeated actions, so that the offline natural gesture modeling process and the online gesture recognition process are simplified, the gesture recognition rate is improved, and the control of natural gestures close to the human habits becomes possible.

Description

technical field [0001] The invention relates to the field of communication and information, in particular to a gesture control device and a gesture recognition method. Background technique [0002] With the development of electronic technology, more and more digital devices such as mobile phones, computers and smart home appliances have become an indispensable part of daily life. In the future, this trend will continue. Existing products will continue to enhance their functions and gradually become more intelligent. New products such as robots and smart cars will also gradually enter the lives of the public. At present, the control of these products is mainly completed through input devices such as remote controllers, keyboards, mice, and touch pads. This method is cumbersome and requires high learning costs for users. [0003] Gesture control, as an emerging operation method, has the characteristics of flexibility, naturalness, and intuition, so it has broad application p...

AI Technical Summary

Problems solved by technology

There are big problems in this way: simple linear motion is easy to grasp, but there are few types, low degree of discrimination, and it is difficult to express complex meanings; complex graphics are quite different from gestures used by people in daily life, which is unnatural and difficult for users High learning cost; existing modeling and recognition methods require a large amount of training data, and cannot easily add new gestures or modify defined gestures
