Problems solved by technology

However, there are mainly the following problems: First, because the EEG signal is extremely weak, it is not suitable for measurement and is easily disturbed, so most EEG acquisition devices need to work in a laboratory with a good environment, and the head needs to be monitored. Special treatment, usually need to wear a special electrode cap, need to apply conductive glue on the electrode, so there are problems such as complicated operation, poor portability, etc., not suitable for use in ordinary daily environments
However, such devices are currently limited to the detection of human body movements (such as arm waving) as control signals

Embodiment 1

[0045] Embodiment 1: Taking the user's control of a toy helicopter as an example, a wireless data receiving module is integrated in the remote controller of the toy helicopter, and the aircraft remote controller converts the received EEG, eye electricity and head movement signals into the toy The control signal and control method of the aircraft can adopt but not limited to the following strategies:

[0046] Concentration EEG parameters: control the flight height of the aircraft, such as the higher the concentration, the higher the aircraft will fly

[0047] Relaxation EEG parameters: control the stability of the aircraft, such as the more relaxed, the better the stability of the aircraft

[0048] Single Blink: Control Aircraft Weapons to Fire

[0049] Head left: control the aircraft to turn left

[0050] Head right: control the aircraft to turn right

[0051] Tilt your head to the left: Control the aircraft to fly to the left

[0052] Tilt your head to the right: control ...

Embodiment 2

[0056] Embodiment 2: Take the case where the user controls the role in the computer game as an example. The computer receives EEG, eye electricity and head movement signals through wireless means (such as Bluetooth communication), and uses these signals to control the role games in the game. The control methods can adopt but not limited to the following strategies:

[0057] Tension EEG parameters: Control the speed of the character, such as the higher the tension, the slower the walk

[0058] Concentration, relaxation, and fatigue EEG parameters: control the character's skills. If the concentration or relaxation reaches a certain level, a certain skill can be displayed. If the fatigue is high, the skill will be restricted.

[0059] Single Blink: Control Weapon Fire

[0060] Blink twice in a row: Control the character to switch weapons

[0061] Head turn left: Control the character to turn left, where the speed of the head rotation controls the speed of the character's turn, ...

Embodiment 3

[0069] Embodiment 3: Taking the user's control of a computer mouse as an example, the computer receives EEG, eye electricity and head movement signals through a wireless method (such as Bluetooth communication), and uses these signals to control the operation of the mouse. The control method can be adopted but not Limited to the following policies:

[0070] Concentration EEG parameters: control the accuracy of mouse movement, such as the higher the concentration, the higher the precision

[0071] Single blink: left mouse click

[0072] Second consecutive blink: Double click with the left mouse button

[0073] Blink three times in a row: right mouse click

[0074] Head left: control the mouse to move horizontally to the left, the speed of head rotation controls the speed of mouse movement

[0075] Head right: Control the mouse to move horizontally to the right, the speed of head rotation controls the speed of mouse movement

[0076] Head up: the mouse moves vertically upwar...

Abstract

The invention relates to a method for controlling a target based on a brain electrical signal and a limb motion signal. In the method, a signal acquiring and processing end and a target controlling end are involved, wherein the signal acquiring and processing end is used for acquiring and processing the brain electrical signal, an eye electrical signal and the limb motion signal of an operator through a portable multi-signal acquiring and processing device, packaging all data and sending the data in a wireless mode; and the target controlling end is used for receiving the data transmitted by the signal acquiring and processing end and converting the data into a control signal for a controlled target, so that the controlled target can be subjected to real-time motion control, accurate motion control and complicated motion control through a plurality of control parameters. The invention also relates to the portable multi-signal acquiring and processing device which is used for comprehensively acquiring the brain electrical signal, the eye electrical signal and the limb motion signal of the operator, packaging the data and sending the data in the wireless mode.

Description

technical field [0001] The present invention relates to the fields of biomedicine, human-computer interaction and electronic technology, in particular to a method for controlling a target to perform complex movements by comprehensively collecting human brain signals, oculoelectric signals and limb movement signals, and a portable Multi-signal acquisition and processing device. Background technique [0002] There are some methods available in the prior art to control a target by detecting brainwave signals and using these brainwave signals as control signals. However, there are mainly the following problems: First, because the EEG signal is extremely weak, it is not suitable for measurement and is easily disturbed, so most EEG acquisition devices need to work in a laboratory with a good environment, and the head needs to be inspected. Special treatment usually requires wearing a special electrode cap and applying conductive glue on the electrode, so it has problems such as c...
