There are thousands of blind or visually impaired throughout the world that struggle with mobility whether it is a daily commute or traversing the living room. Through the years some solutions have surfaced and almost all of them have a draw back, some expensive, some difficult to use daily. Our team's drive is to help these people and create something that is cheap and intuitive to use on a daily basis. This is where the smart cane comes in as it features sensors on the cane to detect incoming objects and send feedback to the user. Thus allowing the user to avoid incoming obstacles.

Project Goals and Key Deliverables
- Working prototype
- Complete documentation package(drawings, bill of materials, analyses, tooling & fixtures, process sheets, test plans & test date)
- Design an assistive device for use by the blind and deaf
- Integrate existing concepts from P14043
- Improve on P14043
- Assembly process to be performed by blind workers
Customer Requirements (Needs)There are a few key customer requirements that are vital to this project. Being able to detect object in the front, right and left of the user while communicating directly to the user. Another is having adequate detection range from the user. The last important need is making sure that the cane is safe to user for the user and environment.

Engineering Requirements (Metrics & Specifications)
All of these engineering requirements are taken and translated from the needs of our customer. They are tangible and can be tested through various methods.

The project constraints are as follows:
- No more than $125 manufacturing cost
- Manufactured and assembled by the blind and visually impaired
- Rechargeable batteries
- No vibrational feedback
All of these constraints are measurable and testable. They have been extrapolated from our PRP and added onto our engineering requirements.
The project team individually applied the plus delta system to each team members contribution. The peer reviews were discussed at a team meeting collectively. Feedback was used to help our team grow as a whole.
