The blind must rely on others when traveling and doing other activities.
To solve this problem to some extent, we are introducing an ultrasonic walking
stick for the blind as well as a portable voice and vibration alarm monitoring
device. An intelligent key has been developed for the visually impaired, with
the help of which ultrasonic sensors can detect obstacles. The blind and the
deaf often suffer from the most basic things of daily life and can put their
lives in danger while traveling, because our country does not have the
necessary equipment to help them avoid the risk. The ultrasonic sensors in hand
combine the properties of sound monitoring and benefit from the blind and
vibrating alarm function, which benefits from the experience of deafness. The
sensor can detect obstacles in the intended range (150 cm) to prevent the blind
from being emitted by emitting a clear sound or a vibration of the deaf
sensation by placing his finger on the button on the top of the device and
vibrating there is a risk. The proposed device is used to guide blind or
partially sighted people. It also offers voice alarm to avoid obstacles thanks
to ultrasonic sensors. The accelerometer also monitors the person's position
and is used to identify the detection of falls. An emergency switch is also
integrated to send an emergency alarm to the persons concerned. The main
advantage of the system compared to other systems in the region is its low
cost, easy transport, reduced power consumption, light weight and it could be
used by technically disabled people.
