| Abstract(in English) | A possiblity for the usability evaluation using eye-movement behaviors was examined with frequency analysis. An input operational task experiment was conducted using a mouse, a keyboard and a keypad, and the traditional subjective system usability measurements (SU-scores) and error rates were measured. Cross spectrum densities (CSD) between horizontal and vertical eye-movements and coherence as standardized CSD in the first second of the experiment followed the same order of the SU-scores or error rates. Also they significantly correlate with the results of the SU-scores and error rates. To determine the frequency range of CSD and coherence for usability assessment, frequency components used as factors were extracted using factor analysis. According to the correlation coefficients between these and the performance of factor scores for predicting the traditional metrics, factor scores of CSD can be better indices for assessing usability than indices of coherence. |
