Description
Summary: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.
