Head tracking driven virtual computer mouse seminar report/pdf/ppt download
Introduction : Recent new applications in Human-Computer Interaction (HCI) and Computer Vision (CV) bring a great opportunity to the improvement of human life.
The future desired Perceptual User Interfaces (PUI) and human inter-face devices require more reliable and fast system performance in dealing with versatile use cases.
Much attention has been focused on the scenario of tracking userís movements with a video camera and translating the motion parameters into semantic indicator symbols to manipulate machine operation.
Camera based perceptual user system provides an alternative solution for convenient device control, which encourages the application of very low bit-rate video-teleconferencing, interactive computer games, machine guided therapeutic gymnastics, robot control, etc.
It also significantly helps the disabled and elder people use limited voluntary actions to communicate with others.
Camera mouse system is such a representative hand-free PUI that tracks human body movement in video to manipulate virtual computer pointing devices to respond user intentions.
In particular, since human head and face embody the focus of attention, head/face tracking based hand-free computer mouse is a more intuitive and convenient PUI solution.
Great progresses in the field of face detection/ tracking and recent advances in hardware have made it possible of building real-time tracking system on common PCs.
Our idea is to use a robust and reliable real-time head tracker for tracking, estimate the course head pose and relative motion simultaneously, and translate the motion parameters to control the virtual computer mouse.
To overcome the drawback of single module system, we integrate the rapid face detection and image-based head tracking as well as design a transition strategy for mode switch when one module fails.
