Intelligent wheelchair system based on brain-computer interface and action method of intelligent wheelchair system

Abstract

The invention discloses an intelligent wheelchair system based on a brain-computer interface and an action method of the intelligent wheelchair system, and belongs to the field of brain-computer interface application research and intelligent wheelchairs. The intelligent wheelchair system based on the brain-computer interface comprises a brain-computer interface system, a control system, a visual system, an intelligent wheelchair body, an execution mechanism and a power supply management system; the brain-computer interface system is used for being connected with the brain of a patient, the control system, the visual system and the execution mechanism are all arranged on the intelligent wheelchair body, the signal input end of the control system is connected with the signal output end of an electroencephalogram signal processor and the visual system separately, and the signal output end of the control system and the signal output end of the visual system are connected with the intelligent wheelchair body and the execution mechanism separately. The system can achieve the basic intelligence, help a patient to complete some most basic life care and improve the self-care ability of the patient and the life quality of the patient.

Description

technical field [0001] The invention relates to the application research of brain-computer interface and the field of intelligent wheelchairs, in particular to a brain-computer interface-based intelligent wheelchair system and an action method thereof. Background technique [0002] The acceleration of population aging will inevitably lead to prominent health problems of the elderly population, and the care and nursing of the elderly, disabled and sick elderly should be paid more attention to by the society. However, due to the imperfection of the development of the medical service industry for the elderly, it is particularly urgent to formulate corresponding countermeasures. [0003] Brain-Computer Interface (BCI) is a novel way of human-computer interface. It is a system based on EEG signals to realize communication and control between the human brain and computers or other devices, independent of the normal output pathways of the brain (peripheral nervous system and muscl...

AI Technical Summary

Problems solved by technology

[0004] At present, smart wheelchairs can realize functions such as autonomous positioning, navigation, and obstacle avoidance, but some patients still need the help of caregivers for the most basic care (pour tea, drink water, open drawers, etc.), and some patients can express it through language or body language their own intentions, but for some patients who have completely lost motor ability and language expression ability, they only retain the thinking ability of normal people, and caregivers cannot really "read" the intentions of these patients
