Cream Cheese and Jelly

A new tool that helps patients rebuild hand-eye coordination by projecting tasks onto the floor. Provides haptic and audible feedback, and saves data to a text file.

Inspiration

The game Operation prides itself on having a stable operator with excellent hand-eye coordination. Our project takes that idea and scales it up a bit! Instead of having to keep a stable hand over surgery, the user will be holding the tool while walking around building hand-eye coordination and arm stability with a probe that can be weighted as needed on the end.

What it does

The tool will help build hand-eye coordination by giving the user a task to trace in the real world with audible and haptic feedback systems. The target audience for this device is physiotherapy patients who are trying to re-develop strength in weaker limbs.

At the bottom of a stick are a distance sensor and a lidar sensor. The distance sensor is responsible for keeping track of how far away it is from the ground. One of the goals for the user is to try and maintain as small of a distance as manageable from the ground. The lidar sensor is responsible for ensuring the user is always within the bounds of the given task. If the user fails to accomplish either task, they're given feedback in the form of vibrations and sound.

In addition, wireless receivers report all relevant data back to a computer where it is stored in a spreadsheet. This allows for progress to be tracked over several sessions.

How we built it

We gather all the supplies needed (the most important being the stick of TRUTH). The stick of TRUTH is our base and holds all of our hardware needs. We made sure to 3D print a bracket to nicely hold our important hardware.

Challenges we ran into

The Ultrasonic sensor is not one of the most reliable modules in the world, a mix of that slight wiring issues presented an enormous challenge. Additionally, the ESP32 modules were difficult to work with when it came to sending data to a computer.

Accomplishments that we're proud of

Our main solderer made one of the most beautiful solder jobs

What we learned

Collaboration requires a lot of communication. When everyone has ideas and is eager to do something, a lot of mix-ups may occur. Clearly stating what you're thinking and what you're planning on doing is essential to the efficient operation of a team.

What's next for Cream Cheese and Jelly

We want to do more projects involving a healthy mix of both programming and hardware. Since we're all ECE students working on integrated circuit research together, being as versatile as possible is essential and we need to get more experience in order to refine our skills as both researchers and students.
