Human-machine interaction method with vision movement related neural signal as carrier

Abstract

A human-computer interaction method based on neural signals relative to the visual movement relates to the technical filed of the human-computer interaction, and is characterized in that the method comprises the following steps: connecting a human-computer interaction unit waiting to be chosen with motional elements started at different times; arranging an EEG electrode in visual movement area of the user head for recording EEG signals; separately extracting brain waveforms corresponding to each motional element in a sequence according to the difference of the time starting; detecting whether an N2 electric potential corresponding with the visual movement; detecting that a human-computer interaction unit corresponding with the simulation of the N2 electric potential is considered as a target for a tested person; finishing the corresponding functional module by a computer, so as to realize the human-computer interaction. The testing results by the system shows that the choosing of a target averagely costs 6 seconds, and both the detection rate and the false reject rate meet the requirement of the regular human-computer interaction. The method has the advantages of having no scintillations, hardly causing the visual fatigue, and being suitable for low contrast and low illumination condition, and different human-computer sites.

Description

technical field [0001] The present invention relates to a human-computer interaction method with nerve signals related to visual movement as a carrier, belongs to the technical field of biomedical engineering and human-computer interaction, and can be used as a new type of computer interaction method for hands-free operation, and can also be used as a method for handicapped people to operate computers. method. Background technique [0002] Human-computer interaction has become an important part of daily life in the information age, and human-computer interaction technology has therefore become an important part of computer science research. Especially in recent years, with the rapid development of computer technology, research on new human-computer interaction technology that is more humanized has become extremely active, and gratifying progress has been made. In addition to the most basic human-computer interaction methods such as mouse and keyboard, it also includes the f...
