  • Abstract:
  • This paper details the complete development of a vision-based human-computer interaction (HCI) framework that leverages thumb gestures for real-time mouse event simulation. Traditional input peripherals often present ergonomic challenges and require physical contact, which is undesirable in various professional environments. Our system utilizes a standard monocular RGB camera and a Python-based processing pipeline (OpenCV, NumPy, PyAutoGUI) to track the user’s thumb. By employing YCbCr color segmentation and contour analysis, we achieved a calibration-free interface capable of executing cursor movement, left/right clicks, and scrolling. The final implementation includes optimized noise filtering and an adaptive gesture recognition algorithm that maintains high accuracy across diverse lighting conditions. Experimental results confirm a recognition accuracy of over 92% with a processing latency of less than 30ms, making it a viable tool for hands-free computing.
