Abstract
We designed a Latin square experiment to investigate the impact of an information system’s usability during human-computer interactions on a user’s physical activity. We studied the effects of the severity of the usability problem on the skin conductance level (SCL) of 24 college students using an analog information system with usability problems as the experimental materials. The results showed that the severity of the usability problems in the information system interfaces did not significantly affect the mean SCL of the subjects during the interactions, but did significantly affect the average absolute value of the first differences of the SCLs (the difference is the rate of change). The significance of the variances in the average absolute value of the first differences in the SCLs was affected by the level of the usability problem’s severity, so this indicator may be used to detect the information system interface usability problem; it should, however, be supplemented with other usability evaluation methods.
