Abstract
A brain computer interface whose operation is transmitted by SSVEP is often investigated to control a wheelchair. The operation is generated by the user’s attention to blinking visual stimulus. In order to avoid various accidents, the user needs to pay own attention to the surrounding situation and visual stimulus, simultaneously. Miura showed the relationship between the position of visual stimulus and the amount of SSVEP. In addition, the amount of SSVEP is rapidly decreased when the visual stimulus is located on the outside of the central visual field. However, a square visual stimulus used in the previous research is not suitable since the distance from eye-sight to visual stimulus is not constant. In this paper, we adopt the circle-form pattern reversal stimulus to clear the relationship between the visual field and SSVEP.
