| Outline of Final Research Achievements |
In order to improve the evaluation environment, we (1) developed a video/sound recording system to multidirectionally analyze the attitudes of subjects and/or cooperators, (2) modified the NASA-TLX (NASA Task Load Index) to evaluate the mental workload on visually impaired persons, and (3) developed voice browser software to help measure memory.
The results of this study show that there might be no difference in short memory between visually impaired persons and sighted persons. Furthermore, a strong correlation was observed between the search time and mental workload in both groups and the measurements and trends of the mental workload when searching the web were similar between the groups. We have presented a definitional formula for lostness in order to clarify the factors that require visually impaired persons to spend more search time than sighted persons.
