Problems solved by technology

However, in order to collect accurate neural signals, silicon chips and electrodes need to be implanted into the human body. At present, there are still great difficulties in technical realization, and the research on the neural decoding of motion information is still in progress.
[0008] Compared with other methods of controlling prostheses, voice control can complete more control functions, is more convenient, and has higher precision. It is not suitable to use voice to control the prosthesis in a quiet place, and it may also cause the prosthesis to malfunction when the patient communicates with others

Embodiment Construction

[0026] The implementation of the present invention will be further described below according to the accompanying drawings.

[0027] The present invention adopts following technical scheme, as figure 1 As shown: it includes an eye image acquisition module 100 , an eye movement feature extraction module 200 , a predefined feature storage module 300 , a feature matching module 400 , an instruction confirmation module 500 and a driving module 600 .

[0028] The eye image collection module 100 is composed of a camera and a transmission device, and its function is to collect images of the eyes in real time and send the images to the eye movement feature extraction module 200 after encoding.

[0029] The function of the eye movement feature extraction module 200 is to extract eye movement features. This module includes three units: blink detection unit 201 , eye rotation direction recognition unit 202 and feature vector storage unit 203 . The blink detection unit 201 analyzes eye i...

Abstract

The invention discloses a control system and a control method for controlling the upper prosthesis to move by using eye movement signals. The control system comprises an eye image acquisition module, an eye movement characteristic extraction module, a predefined characteristic storage module, a characteristic matching module, an instruction confirming module and a driving module. By all the modules, the combination of the rotation event and the blinking event of the eyes is realized, and then various different characteristics are generated, so that more control functions are completed.

Description

technical field [0001] The invention relates to upper limb prosthesis technology in the technical field of rehabilitation aids, in particular to a control system and method for upper limb prosthesis. Background technique [0002] How to allow the disabled to control the upper prosthesis conveniently and flexibly is a very important content in the research of upper prosthesis. At present, the bionic control signals used in the control of upper prostheses in the world mainly include the human body's own myoelectric signals, EEG signals, nerve signals and voice signals. [0003] The basic principle of using myoelectric signal to control the prosthesis is: the action potential generated when the muscle contraction of the residual limb is drawn out from the skin electrode, amplified by the bioelectric amplifier, and then sent to the computer for analysis, and the effective features reflecting the willingness to exercise are extracted, and the feature vector and The mapping relat...
