After researching today's solutions for sight-impaired individuals and not finding any reliable, smart, and affordable solutions, we have decided to come up with our own.
What it does
EyeSight cane uses ultrasonic sensors to detect obstacles, stairs, and steps. It alerts the user of the presence of these obstacles by activating the vibration motors that are integrated into the cane. The closer the person gets to these obstacles, the more intense the vibration gets.
How we built it
The EyeSight smart cane is built using ultrasonic sensors, vibration motors, raspberry pi zero, and a PVC pipe for the enclosure.
Challenges we ran into
- Drilling through a PVC pipe
- Finding a PVC pipe
- Hardware selection
Accomplishments that we're proud of
- Creating an optimal solution within 24 hours
- Going to home depot twice during the event
What we learned
- Controlling the vibration frequency
- How to interface sensors with hardware
What's next for EyeSight
Develop the companion mobile app for onboard directions, create an inductive charging solution for the white cane, build integration with smart home devices for pinging the cane if it is lost.
