Project Summary

A Virtual Cane is a hands-free device that assists individuals with low vision to avoid obstacles and navigate through unfamiliar paths. The device allows users to gain independence by giving them a better sense of their surroundings. The device must address three main aspects : Localization, Orientation, and Obstacle Avoidance. Currently, Visually Impaired People (VIP) use regular white canes to avoid obstacles that might be in their way.

The goal of this project is to design a device that provides the user with appropriate feedback, is comfortable to use, and works for individuals with low cognitive ability. The expected end result is a proof-of-concept prototype that functions in a constrained environment, and a technical paper that discusses the technology and design attributes of the device. The resulting prototype needs to be safe for use, must not inhibit the user from pursuing desired activities, and must test to the ABVI limit.
