Indoor Orientation and Mobility for Learners Who
are Blind 165 - 170
Mauricio Sáenz, Jaime Sánchez
AB STRACT
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 Po cketPC device interface deve lopers
to be able to de fine 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, efficie ncy, and
availability. The results of the usability evaluation assured us that
the interface de signed and de veloped is usable for users who are
blind, which is reaffirmed through the accessibility e valuation. 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 nav igation.
