Abstract
The display-control compatibility was an important principle of the interface design which included the display part and the control part at the same time. The study investigated the effect of different display-control compatibility designs of 2 samples intelligent electric rice cookers on the different user groups’ operating performance. A 2 (display-control compatibility: high vs. low) × 3 (different user groups: youth group, middle-aged group and elderly group) within-subject factorial design was used in this experiment. The usability testing method was adopted. The subjects’ electroencephalo-graph (EEG) was recorded over the whole experiment. The results showed that the task completion rate of the intelligent electric rice cooker with high compatibility design was higher than that of the low compatibility design between the youth group and middle-aged group, but the situation of the elderly group was reverse. The task error rate and the operation time of the intelligent electric rice cooker with high compatibility design were lower than that of the low compatibility design cooker among the three groups, which of young group was less than that of middle-aged group and elderly group. The main effects of the operation time of display-control compatibility and user group were significant. The operation satisfaction of the cooker with high compatibility design was higher than that of the low compatibility design. The emotional fluctuation of intelligent electric rice cooker with high compatibility design was smaller than that with low compatibility design. In short, the usability of the high compatibility intelligent electric rice cooker was apparently higher than that of the low compatibility intelligent electric rice cooker among different user groups.
