Abstract
Acceptable limit for delay in response of computers was investigated, by means of an experiment in which 27 subjects played specially designed Othello game with delay in response. Subjects are split into two groups, one of which consists of 5 impatient subjects with patience rate with delay in response below 25%, and the other one of which consists of 22 subjects with patience rate over 70%. Further 22 subjects are split into two groups, one of which consists of 11 subjects with patience rate of 75〜97%, and the other one of which consists of 11 subjects with patience rate of 100%. Acceptable limit of delay time of impatient group would be 2s because they can wait for the response of computer at clicks under only 13% to all clicks in case of delay time over 2s. Acceptable limit of delay time of medium group might be 3s, but even than they can wait for the response at clicks over 86% to all clicks.
