Problems solved by technology

[0003] Due to the immaturity of the current brain wave acquisition technology, many brain wave controls are very random, and are easily disturbed and very unstable.
Moreover, there are contradictions in the accuracy and portability of relevant brain wave acquisition sensors at home and abroad: the use of high-precision brain wave acquisition equipment requires users to shave their hair and apply silicone on the head, which is inconvenient to wear, so it cannot be used by most people. Accepted; and the high-precision brain wave acquisition sensor is easy to wear and has a beautiful appearance, but due to the low accuracy of the collection and the great interference, it has been impossible to analyze the actual thoughts of various users, and can only simply judge the user's forehead thinking band range
Therefore, wheelchairs purely controlled by brain waves only exist in laboratories and cannot be put into production, and when using them, users need to be highly focused at all times, which puts a lot of burden on the disabled
[0004] To sum up, there is a strong demand for brain-controlled wheelchairs at this stage, but purely brainwave-controlled wheelchairs cannot be put into production in the short term and have poor usability. Therefore, it is urgent to find a solution for brain-controlled wheelchairs

specific Embodiment approach 1

[0033] Specific implementation mode one: combine figure 1 , 2 3. Describe this embodiment. In this embodiment, a wheelchair control method based on brain waves combined with head movements uses brain waves combined with user head movements to control the wheelchair, wherein the brain waves are used to control the start and stop of the wheelchair. There is no need to worry about interference; the user's head movement is used to control the movement of the wheelchair, using the head movement to control the movement of the wheelchair in eight directions including front, rear, left, and right. The operation is simple, and the user can easily control the movement of the wheelchair without concentrating.

specific Embodiment approach 2

[0034] Specific implementation mode two: combination figure 1 , 2 , 3, 4, 5, 6, 7, 8, and 9 illustrate this embodiment, and the control method described in this embodiment includes:

[0035] Step 1: Collect brain wave information and analyze whether the user wants to start the wheelchair; when it is detected that the user's brain sends a command to start the wheelchair, start the wheelchair and wait for the user's direction control;

[0036] Step 2: When the wheelchair is in the starting state, the user controls the motion state of the wheelchair through head movements, including forward, backward, left turn, right turn, left forward, left backward, right forward, and right backward; keep the head movement to realize the wheelchair Continuous movement, after the head movement returns to the original position, the wheelchair pauses and returns to the direction control state waiting for the user;

[0037] Step 3: When the brain is detected to issue a stop command, the wheelcha...

specific Embodiment approach 3

[0047] Specific implementation mode three: combination figure 1 , 2 , 3, 4, 5, 6, 7, 8, and 9 illustrate this embodiment. The collection of brain wave information and head movements described in this embodiment is completed by a single head-mounted device, that is, the brain wave acquisition device and head movements The acquisition device is integrated on a single headset.

Abstract

The invention mainly relates to a control method and a control device, in particular to a wheelchair control method and control device based on brain waves and head movements. A wheelchair is controlled through the brain waves and the head movements of a user, the brain waves are used for controlling starting and stopping of the wheelchair, and the head movements of the user are used for controlling the moving modes of the wheelchair. The control device comprises a multi-axis sensor, a brain wave acquisition module, a wheelchair controller, a processor, motors, the wheelchair and a battery. The multi-axis sensor and the brain wave acquisition module are integrated on a single headset device and connected with the input end of the processor, the wheelchair controller is connected with the output end of the processor, the output end of the wheelchair controller is connected with the motors, and the wheelchair controller, the processor and the motors are all fixed to the wheelchair. The control method and the control device solve the problems about usability and stability of the wheelchair controlled by the brain waves.

Description

technical field [0001] The present invention mainly relates to a control method and a control device, and more specifically, to a wheelchair control method and a control device based on brain waves combined with head movements. Background technique [0002] In recent years, with the improvement of the level of science and technology, the research on brain waves has become more and more in-depth, and its application has become more and more extensive. Among the equipment for assisting the elderly and the disabled, technologies that rely on muscles, body movements, voice commands, and brain waves to control wheelchairs have received high attention. The human brain is the control center of behavioral activities. It is the wish of countless people with disabilities to let machines be directly controlled by the brain, so that they can realize their ideas more simply and freely like ordinary people. In recent years, many brain wave wheelchair projects have emerged, all of which u...
