  • Implement calibration systems and modular architecture for easy future feature expansion.
  • Ensure responsive and stable avatar control based on real-time body motion input.
  • Provide source code, build instructions, a performance report, and a comprehensive testing checklist.
  • Optimize for stable operation over extended use and meet specified performance and UX requirements.
  • Prepare the prototype for future enhancements and additional features.

Requirements

  • Proven experience developing mobile games or interactive prototypes in Unity (preferably Unity 6 LTS).
  • Strong knowledge of AR Foundation, ARKit, ARCore, and/or MediaPipe Pose for body tracking.
  • Demonstrated ability to design modular, scalable game architectures.
  • Experience with camera-based motion tracking and calibration systems.
  • Proficiency in C# and Unity development best practices.
  • Ability to deliver clear documentation, build instructions, and performance reports.
