In the first report, we have proposed a quantitative evaluation system for attentional deficit using a personal computer. However with the experiments, we noticed the various problems on the system. For example, the former system required too much time to carry out the entire task. For this reason, the concentration of the subjects showed decline with time. Therefore, in this paper, we report on the some improvements of the system and in addition on a new measurement method of hemianopsia influence.
