One of our team member's grandparents has become visually impaired, so we had the idea to create a wearable gadget to help people like him navigate the world. This project was submitted to Lemelson-MIT Inventeam, a national competition to create an innovation to benefit society.

This is a wearable gadget that transduces the distance of obstacles to haptic feedback in order to better visualize one's surroundings.

The device consists of 3 main parts: a 3D printed cast to hold the electronics in the shape of a neckband, an arduino circuit to combine ultrasonic sensors, haptic feedback motors, and the microcontroller, and finally the program to create the actual function.

There was initial difficulty coordinating all parts of the project. In the end, we learned effective communication skills and gained experience in the prototyping cycle.

We successfully created and prototyped a device that helps visually impaired people navigate the world, which has the potential to benefit society.

• Arduino
• Adafruit Motorshield

Once the battery pack is connected and the driver program is uploaded, the motors will automatically begin to vibrate based on one's distance to their surroudings.
