that the flashes of the non-target near to the target may attract the user’s attention and pro-

duce P300. The findings that step 2 performed better than step 1 can be interpreted that the

adjacent area of contact in step 1 was larger than that in step 2. As a result, the subjects in

step 1 scattered more attention in the non-target area near to the target than those in step 2.

Partitioned by ERS, the target in the graph can be sketched and retained its most original

information (see Fig. 3). The discrimination among the subjects is significant in Table 2,

which indicates that the accuracy is closely related to the complexity of the background

image. The three subjects obtained an average selection accuracy of more than 75% (Table 2)
