Summary
This study introduces a portable computer vision hand-tracking system using a Leap Motion Controller 2 and single-board computer. The mobile solution offers natural interaction for various applications without external power.
Area of Science:
- Computer Science
- Human-Computer Interaction
- Robotics
Background:
- Computer vision (CV) hand tracking offers touchless interaction but traditional systems lack portability.
- Stationary cameras and high computing demands limit CV systems in mobile applications.
Purpose of the Study:
- To develop a portable, self-powered hand-tracking system for mobile applications.
- To evaluate the system's performance and robustness under various conditions.
Main Methods:
- A portable system was designed using a Leap Motion Controller 2 (LMC) mounted on the head.
- A single-board computer (SBC) powered by a compact power bank controlled the system.
- Experimental tests assessed robustness against variable lighting, power consumption, CPU usage, temperature, and frame rate.
Main Results:
- The system demonstrated robustness under variable lighting conditions.
- Low power consumption and CPU usage were observed.
- The system maintained a suitable frame rate for mobile applications.
Conclusions:
- The developed portable hand-tracking system is lightweight and self-sufficient.
- This solution is suitable for mobile applications requiring natural, touchless interaction.
- The system overcomes limitations of traditional CV-based hand tracking.
