Intelligent household electric appliance control nursing device and method based on multi-mode brain-computer interface

Abstract

The invention discloses an intelligent household electric appliance control nursing device and method based on a multi-mode brain-computer interface. The device comprises a visual stimulation screen, an EEG signal collection system, a computer, a controller and an equipment terminal, wherein the visual stimulation screen, the EEG signal collection system, the computer, the controller and the equipment terminal are mutually connected. The device detects whether a P300 level and an SSVEP are generated in the same target key group at the same time or not, so as to discriminate the idle / control states of a system. The device selects a to-be-controlled household electric appliance and the control of related operation through the brain-computer interface based on the P300. The device and method provide a new nursing mode for paralytic patients (SCA, ALS, etc.) who stay on a bed for a long time. The paralytic patients can autonomously achieve the posture change on the bed, so as to prevent bedsore. Meanwhile, the device and method can achieve the operation control of various types of household electric appliances on the bed, thereby improving the living quality. The device and method can accurately discriminate the idle / control states of the system, are high in recognition rate, are complete in function, are high in practicality, and can be used for the paralytic patients.

Description

technical field [0001] The invention relates to the field of auxiliary devices for severely paralyzed patients, brain-computer interface application research and human-computer interaction, in particular to an intelligent home appliance control nursing device and method based on a multi-modal brain-computer interface. Background technique [0002] Although there are already many smart devices on the market to help paralyzed patients improve their quality of life. Such as voice control, manual remote control switch control and timing control and other equipment. But for those with severe paralysis, such as amyotrophic lumbar sclerosis (ALS), spinocerebellar ataxia (SCA) and vegetative people, they retain the thinking of normal people, but they can only communicate with vision. Communicate with the outside world. If these patients can control home appliances such as nursing beds and televisions, their quality of life will be greatly improved. Such as controlling the nursing...

Problems solved by technology

Although there are already some EEG-based nursing beds, EEG-controlled lamps, etc., they need to keep staring at the flashing keys, and they are prone to wrong instructions in the idle state
