ABSTRACT
Project

BATEYE fundamentally uses an ultrasonic
sensor mounted on to a wearable pair of glasses
that measures the distance to the nearest object and
relays it to an Arduino board. The Arduino board
then processes the measurements and then plays a
tone (150-15000Hz) for the respective distance
(2cm to 4m) till the data from the second ultrasonic
pulse (distance) comes in, and then the same
process gets repeated. This cycle is repeated almost
every 5 milliseconds. The person hears sound that
changes according to the distance to the nearest
object. The head provides a 195-degree swivel
angle and the ultrasonic sensor detects anything
within a 15-degree angle. Using systematic,
cognitive and computational approach of
neuroscience, with the hypothesis that the usage of
the occipital lobe of blind people goes into
processing other sensory feedback., and using the
brain as a computational unit, the machine relies
on the brain processing the tone produced every 14
mS to its corresponding distance and producing a
soundscape corresponding to the tones and the
body navigating using the same. During
experimentation, the test subject could detect
obstacles as far away as 2 – 3m, with horizontal or
vertical movements of the head the blindfolded test
subject could understand the basic shape of objects
without touching them, and the basic nature of the
obstacles.
