I had to rehabilitate after disc surgery, but it was useless when the belly fat is intact. My doctor friend said that cycling is good for diet. So I decided to ride a bicycle; however, I thought it was not yet appropriate and I bought an indoor bicycle as an alternative.

Indoor cycling is good for health but it is not fun! As a result, I decided to make it fun! My project uses an Arduino Leonardo and Hall sensor as the main equipment. Use the Hall sensor to detect the rotation of the bicycle, along with the Unity3D racing game starter kit.

EXPANDED TECHNICAL DETAILS

Exer-Gaming Integration Architecture

Super Diet transformed a physical stationary exercise bike into a high-performance controller for PC racing games like Unity-based sims.

  • Pedal-to-Throttle Mapping: Captures the RPM of the physical pedals using a hall-effect sensor or magnetic reed switch. The Arduino translates the pedaling speed into a "Throtle" signal, forcing the player to exert effort to move in the game.
  • UART Serial Bridge to PC: The Arduino sends real-time speed data over serial. On the PC side, a custom script translates these serial values into virtual keyboard/controller inputs.

Creative Strategy

  • Inertia Tracking Algorithm: The firmware includes a "Momentum" calculation; if the player stops pedaling, the virtual car slowly coast to a stop, mimicking the physical feeling of a heavy flywheel.
