The effects of correct and transformed visual feedback on rhythmic unimanual visuo-motor tracking were examined, focusing on tracking performance (accuracy and stability) and visual search behavior. Twelve participants (reduced to 9 in the analyses) manually tracked an oscillating visual target signal in phase (by moving the hand in the same direction as the target signal) and in antiphase (by ...

Robust hand tracking is highly demanded for many realworld applications relevant to human machine interface, however, current methods achieves no satisfactory robustness in real environments. In this paper a novel hand tracking method was proposed integrating online Hough Forest and Flocks-of-Features tracking. Skin color was integrated in the Hough Forest framework, gaining more robustness aga...

Recent approaches to real-time bare hand tracking estimate the hand’s pose and posture by fitting a virtual hand model to RGBD sensor data using inverse kinematics. It has been shown that exploiting natural hand synergies can improve the efficiency and quality of the tracking, by performing the optimization in a reduced parameter space consisting of realistic hand postures [SMRB14]. The downsid...

In this paper, we present a vision based relative tracking for use in hand-held virtual reality systems. Hand-held virtual reality system refers a virtual reality system that is self contained with a computer and multimodal sensors (e.g. 3D tracking, voice recognition, motion sensing, etc.) and feedback (e.g. graphic, sound, and tactile display) all hold-able in one hand. Relative tracking refe...

In this thesis, we present the creation process of a virtual 3D hand model with sufficient accuracy and flexibility for the tracking of a human hand. The model consists of an underlying skeleton and a skin surface. The skeleton is implemented as a hierarchical joint structure with 17 joints and 26 degrees of freedom. We define an extra imaginary joint at the palm to model the movement of the CM...
