Abstract
Conveying spatial information to visually impaired people is possible by leveraging residual tactile abilities. It is still unclear how to effectively evaluate mental map construction beyond performance-based metrics. Here we use a minimalistic mouse-shaped tactile device to display tactile virtual objects. We study how task complexity and visual deprivation influence behavioral, subjective and performance variables both in blind and sighted subjects. Complexity shows to be a factor equally affecting both groups. As well we show that performance, amount of acquired information and subjective judgments of task difficulty do not depend on visual deprivation. Results can help with technological solutions in rehabilitation programs for impaired individuals.
