This paper discusses how assistive technologies for visually impaired people (VIP) can be used to assess and compare the physiological reactions of sighted individuals and visually impaired individuals (VIM) while performing identical tasks. Galvanic Skin Response (GSR) signals were recorded from two distinct groups, consisting of 10 blind individuals and 10 visually impaired persons. The objective was to investigate the relationship between GSR measurements and the different degrees of mental exertion among the groups, thus underscoring their vital role in enhancing overall classification performance. The analysis indicates that the GSR signals in the visually impaired group are more uniform and exhibit reduced variability in the characteristics compared to the sighted people. Results highlight the utility of GSR in elucidating how visual impairment can affect cognitive and emotional processing during task execution by providing an understanding of the cognitive load unique to blind people for the potential creation of a data set specific to them.

摘要

This paper discusses how assistive technologies for visually impaired people (VIP) can be used to assess and compare the physiological reactions of sighted individuals and visually impaired individuals (VIM) while performing identical tasks. Galvanic Skin Response (GSR) signals were recorded from two distinct groups, consisting of 10 blind individuals and 10 visually impaired persons. The objective was to investigate the relationship between GSR measurements and the different degrees of mental exertion among the groups, thus underscoring their vital role in enhancing overall classification performance. The analysis indicates that the GSR signals in the visually impaired group are more uniform and exhibit reduced variability in the characteristics compared to the sighted people. Results highlight the utility of GSR in elucidating how visual impairment can affect cognitive and emotional processing during task execution by providing an understanding of the cognitive load unique to blind people for the potential creation of a data set specific to them.
