Visual aid a next generation concept

The conventional visual aids use a simpler procedure in guiding the individuals. These devices warn the individual through physical contact which might be life threatening in a few cases. Today wearable devices are revolutionary by their extensive uses to humans. The gadgets do a lot of things useful to the user. Our idea throws light into a newer dimension to the wearable devices to visually impaired individuals. The idea arose due to the practical difficulties faced by them. The main difficulty is finding the path in front of them, taking action/making responses to tackle the obstacles. This device works based on the visual guiding in bats, which is they use high frequency ultrasonic waves to find obstacles and make responses. The generation of pulses and receiving of pulses helps the device to sense the obstacles and alarm the user. The obstacles are identified based on the time interval between the sending and receiving of the signal.
