Comparative Evaluation of Sighted and Visually Impaired Subjects using a Mobile Application for Reducing Veering during Blindfolded Walking
Journal Title: Acta Technica Jaurinensis - Year 2016, Vol 9, Issue 2
Abstract
Measurements were conducted using a navigational application on an Android Smartphone that provides auditory and haptic feedback based on electromagnetic sensor data (compass) in order to help users walk in a straight line. Blindfolded sighted subjects attempted to walk along a 40-meter path with and without navigational assistance. Results showed that optimal settings of accuracy, sensitivity and target direction on the device can significantly reduce veering. Further, it was shown that even a short training session consisting of four trials could lead to better subsequent performance without navigational assistance.
