Abstract

Brain-Computer interfaces (BCIs) have been studied by using transient visual evoked potential (VEP) with various blinking stimuli. We examined to change the phase and the frequency of the blinking light with variable onset interval and changing luminance in order to realize multiple choices in the BCI using transient VEP. However, the number of the multiple choices was limited to four choices. Therefore, we examined to change the luminance of the blinking stimulus in order to increase the number of multiple choices. In this study, we try obtained VEPs based on synchronous addition method, and verified effects of changing luminance and lighting interval of indicators. In addition, we develop multiple choices interface by using blinking light with variable onset interval and changing luminance. In this paper, we report the possibility of multiple choices by experiment of estimate for proposed methods.
