Ultrasonic Haptic Vision System

The ultrasonic haptic vision system enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the user’s head.

The main aim to make this project was to construct a sixth sensory system that interacts with the body in an intuitive and user friendly fashion and enables the user to navigate without vision.

In this project, RF transmission is also implemented in order to provide feedback to a program running on the computer to keep track of the sensory data obtained from the mobile user mounted sensor system. This enabled the person sitting at the computer to observe all the distances between the surrounding obstacles and the user wearing the hat. The rangefinder rotated on a motor atop the hardhat in order to take the sensory data at discrete points around the user.

The hat and required hardware is all battery powered, so that it is totally mobile and can be used as intended, so that movement is not restricted by the length of wires.


The software design for this project was implemented using a modular approach on both the transmitter and receiver sides of the system because of its efficiency and ease of implementation. However, we implemented 2 kinds of execution synchronizations on either side of the system.

This project includes, MATLAB code, hardware implementation, software implementation, full working, block diagram, etc.
