Ringinator

The repository for my 3D-printed ring-shaped motion-control presentation control and pointer device written in C++ and TinyML and implemented with a TinyS3 microcontroller. The Bachelor thesis is written in Typst.

Goals

The goal is to develop a prototype device shaped like a ring that can be used to control presentations and as a laser pointer using only motion controls.

1. Maximum compactness Everything needs to be small, the software should be minimalistic (ideally as much processing on the TinyS3 as possible)
2. Wirelessness

Planned commands:

Shaking your hand while pointing at the screen	Shaking your hand while pointing down	Pushing your finger towards or away from the screen	swiping your hand left and right	circling with your finger (counter-)clockwise	WIP
Activating the laser/computermouse mode	Disabling the laser/computermouse mode	left and right clicking	changing the volume	changing the slides forwards and backwards	pointing your figer up for 2 seconds

My goal is to work on my bachelor thesis every day 18:00 and when I'm in the library at the university

Project roadmap

• April: Hardware & Networking
  • Creating a Typst template for bachelor theses at the UHH
  • Creating the model for the ring
  • Wiring the components together
  • Soldering the components together
  • Creating the hull containing the components
  • Establishing a connection between the TinyS3 and the PC
  • Write the first chapters (State of the art and goals)
• May: Software:
  • IMU-Visualization
  • Sensor-fusion
  • Driver
  • Setting up TinyML
• June: Training and evaluating the models

To-Dos this week

• Write the summaries of the 8 state of the art papers in the State of the Art chapter
• Write the sources for the TinyML tutorials in the introduction
• Establish bidirectional Bluetooth communication and visualize the output from the ESP32
• Solder the headers onto the TinyS3
