The engineers at the University of Nevada, Reno
launched a new system alias Navatar. This system provides a great assistance to
blind or visually-impaired person by allowing them to locate through a large
building (a hospital, lab, office etc) easily.
Navatar uses the sensors in a smartphone
to detect progress along a map of a building.
In this system a 3-D
map of the building is generated with SketchUp program. The user places it in
their starting point and destination and the system provides them turn-by-turn
directions and at the same time, calculates footsteps and notices changes in
orientation so as to obtain a rough idea of the position of the user in the
building.
By utilizing the sensors in the phone and map
data, Navatar can trace the user to
within six feet and perfectly find someone into the surrounding area of their
destination. Besides, this new system can also give dictation by telling "turn
right, then second door on the left," etc. and thus help user to
easily find the way into the area.
This new system can also be helpful in some
other situation like when a fireman is navigating a smoky and unknown building
or a person is locating their way around a large area as for instance an
airport.
