Head-mounted electro-oculogram control intelligent wheelchair and control method thereof

Abstract

The invention discloses a head-mounted electro-oculogram control intelligent wheelchair and a control method thereof.The intelligent wheelchair comprises a head-mounted device and a wheelchair end device, and a signal collection module in the head-mounted device collects electro-oculogram signals in real time, preprocesses the electro-oculogram signals and converts the electro-oculogram signals into digital signals in an analog-to-digital mode; the feature extraction and recognition module performs feature extraction and recognition to obtain eye movement information, and sends the eye movement information to the processing control unit; the processing control unit recognizes a control intention of a user according to a control discrimination algorithm and sends a control instruction to a motion execution mechanism in the wheelchair end equipment; a motor in the motion execution mechanism drives the wheelchair body to execute corresponding control actions according to the received control instruction; the rechargeable battery supplies power to the head-mounted device and the wheelchair end device. Through the head-mounted device convenient for the user to wear, the user can operate the intelligent wheelchair to move in real time through eye movement instead of fingers, two hands are liberated, and the intelligent wheelchair can adapt to more application occasions.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to an intelligent wheelchair controlled by a head-mounted ophthalmoscope and a control method thereof. Background technique [0002] With the progress of our society, ensuring and improving the quality of life of the disabled has received more and more attention from all walks of life. Surveys have shown that enhancing the mobility of the disabled and the elderly is not only beneficial to their daily convenience, but also effectively protects their mental health. Therefore, the wheelchair has become an important tool necessary for the life of such disabled people. Traditional wheelchairs require users to be driven by hand or pushed by others, which is very inconvenient. Electric wheelchairs save manpower and provide convenience for users. However, most of the electric wheelchairs on the market currently rely on hand-controlled joysticks to operate, which is not...
