Problem Statement

The blind and visually impaired predominantly utilize the white cane, a device that allows the user to detect objects in front of them and allow them to navigate the world. However, this tool does not have the ability to help detect distance (outside the length of the white cane),depth of objects in the environment without physical contact, and objects in motion.

Project Goal

To create a system that will help the visually impaired and blind navigate the environment around them.

The system should be light weight and not impede motor function
Give effective feedback to the user to make appropriate decisions on movement

Specifications

Will assist a user in navigating around typical obstacles located in an indoor setting, all without the use of their vision. Objects larger than 5cm off of the floor will be considered obstacles.
Will be able to make distance and orientation measurements of objects in the environment, and provide feedback within a <500ms period.
Provides feedback to the user regarding the distance and direction of objects in the environment with a centimeter distance accuracy and 30 degree angular resolution.
Informs the user of any errors that affect the functionality of the system.
Supplies enough power to operate for at least 3 hours.
Provides clear feedback regarding the remaining amount of power.
Power source is rechargeable/interchangeable.
Will not impede the user’s innate motor functions and the distance detection system will not weigh more than 500 grams.
