Embodiment 1

[0031] The following is a specific description of the brain-controlled browser of the present invention in conjunction with the accompanying drawings:

[0032] (1) Preparation: The user puts on the hair band or electrode cap according to the standard electrode position of the 10-20 system, and ensures that the four electrodes FP1, FP2, Cz, and Oz are in the connected state (for the hair band, ensure that the dry electrode is in contact with the scalp Good; for the electrode cap, pour in the conductive paste and make sure the impedance is below 5 kΩ). Open the mind-controlled browser program, so that the mind-controlled browser stays in the figure 1 The list browsing interface shown.

[0033] (2) Browsing of the title list: After the initialization of the system is completed, the system is in the list browsing interface. At this point, the user can browse the title list in the webpage. Three pieces of news are presented to the user on each page, and the user can browse more ...

[0038] (1) Browsing strategy for brain-computer interface technology

[0039] (1.1) List / Content Browsing Architecture

[0040] Mind-controlled browsers are very different from ordinary browsers in terms of requirements. It focuses more on the simplification of browsing mode and the simplicity of information presentation. The invention refines and extracts the browsing mode of the browser in design, and uses the (list / content) framework to realize the main functions of the browser.

[0041] A conventional website contains a wealth of information, which is displayed on different pages in different forms, and finally forms a large number of browsed pages. Nevertheless, numerous browsing pages can be classified into two types, namely information title pages and information content pages. Only through these two pages, users can complete the browsing of all website information. According to this characteristic, and considering the application characteristics of the brain-compute...

Abstract

The invention discloses a full-automatic webpage browsing control method based on a brain-computer interface. A P300 brain-computer potential is used for controlling the position of news that a user wants to watch in a browser, the news to be played is confirmed through blink detection, after the position of the news is confirmed, a news content interface is entered, and when relevant detailed content is read, steady state visual evoked potential (SSVEP) is used as an index of signal detecting and for conducting page-up, page-down and returning operation on the news, browsing interested news in detail, returning to a news list page and exiting the browser. The method has the advantages of being simple in operation and wide in application range, providing a chance for disabled people to browse internet information and being capable of being used under the condition that the body or a mouse can not be moved due to external or personal factors.

Description

technical field [0001] The invention relates to a method for automatically controlling webpage browsing based on a brain-computer interface. Background technique [0002] In real life, there are many disabled people who lack motor function. Among them, the general paralyzed people have lost the ability to communicate with the outside world through language or body, but they have complete consciousness. Therefore, how to improve their quality of life has become a widely concerned issue. In cases where such damage cannot be repaired, the "Brain-Computer Interface (BCI)" is a communication system that does not depend on the normal output pathway composed of peripheral nerves and muscles. Human-computer interaction system, which can directly convert the information sent by the brain into commands that can drive external devices, and replace human limbs or language organs to achieve communication between humans and the outside world and control of the external environment. This...
