Problems solved by technology

But this invention is only limited to typing, and it needs to be connected with a specific device. It is bulky, inconvenient to operate, and has a narrow application range. It uses round-robin highlighting to type, and can only issue a complete control command after multiple blinks of output. Single control function, slow typing speed

Embodiment Construction

[0049] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0050]The present invention will be based on five typical electro-oculogram signals (look up, look down, look to the left, look to the right, and blink), and convert the eye electro-signals into control commands through related circuits and algorithms to realize Control of the mouse. The invention is not only simple in structure, but also wearable, low in cost, fast in response, and has high market application value.

[0051] The present invention includes an oculoelectric data acquisition and analysis part and a bluetooth mouse control part based on the oculoelectric data.

[0052] The data acquisition and analysis part enters the interruption of collecting the electrooculogram data through the timer, and sets the timing time of the timer to de...

Abstract

The invention discloses an electro-oculogram collecting method and a Bluetooth mouse system based on electro-oculogram control; through the electro-oculogram processing method, the method can recognize the eye's actions of looking leftwards, rightwards, downwards, upwards and blinking twice, and define different mouse operations corresponding to different eye's actions. The Bluetooth mouse system based on the electro-oculogram control comprise an electro-oculogram collecting electrode, an electro-oculogram collecting module, an analog-digital converter, a digital signal processor, a Bluetooth module and a power module. The Bluetooth mouse system is used for realizing different operations of a user by controlling the mouse through the eye's actions, thereby helping patients with deficiency of both arms to surf the internet by an electronic device as an ordinary person. The Bluetooth mouse system is simple in circuit structure, small in volume, convenient to carry, strong in antijamming capability, and can be widely applied to the mobile medical treatment, household patient nursing and other fields.

Description

technical field [0001] The invention belongs to the technical field of biological information, in particular to the identification and control technology of electrooculogram signals. Background technique [0002] The patient's limb motor dysfunction seriously affects his ability to communicate with the outside world. Traditional human-computer interaction equipment, such as keyboards and mice, cannot meet the needs of patients. To meet the needs of the above-mentioned special population, it is a feasible solution to develop some new human-computer interaction devices that do not depend on the limbs, and it is an important technical means to realize human-computer interaction by using the human body's own bioelectrical signals. [0003] For example, the Chinese invention patent application with the publication number CN102662473 disclosed on September 12, 2012 "A device and method for realizing human-computer information interaction based on eye movement recognition". The dev...
