Abstract

This study consisted of designing a mobile technology to identify the position and orientation of people who are blind in closed environments, such as a school, building or home, identifying the necessary infrastructure based on criteria of usability, reliability and accessibility, in order for PocketPC device interface developers to be able to define the technology to be used at an early stage. The technology consisted of using PocketPC devices with a data collecting application and another for the representation of space. We evaluated its usability, accessibility, reliability, efficiency, and availability. The results of the usability evaluation assured us that the interface designed and developed is usable for users who are blind, which is reaffirmed through the accessibility evaluation. The reliability, efficiency and availability evaluations of the system show that a user who is blind can use the system confidently, because it provides correct information for more independent navigation.
