要約(日本語): It is known that stimuli’s intensity is proportional to the amplitude of Steady State Visual Evoked Potential (SSVEP). We believe that this phenomenon can be applied to brain-computer interface research. For application purpose, this article presents a method to enhance the amplitude change and to analyze time delay caused by the attention switch from low intensity stimulus to high intensity stimulus or from high intensity stimulus to low intensity. Our preliminary results indicated that amplitude of SSVEP obviously changed within 2 seconds after subjects changed their attention.
