TLDR
The authors present a hand model that simultaneously satisfies both the synthesis and analysis requirements of model based compression and is ready to be incorporated into a virtual environment or model based compressed scheme such as sign language communication over telephone lines or virtual teleconferences over computer networks.Abstract:
The authors present a hand model that simultaneously satisfies both the synthesis and analysis requirements of model based compression. The model can be fitted to any person's hand and can be done using a single camera. Once the model is fitted to a real human hand, it is then used in several tracking scenarios in order to verify its effectiveness. With successful tracking achieved, the model is ready to be incorporated into a virtual environment or model based compression scheme such as sign language communication over telephone lines or virtual teleconferences over computer networks at very low bit rates and at very high image quality. >read more

The kinesiology of the thumb trapeziometacarpal joint.
TL;DR: A position of adduction and flexion of the trapeziometacarpal joint was most common during thumb function, and both the trapezium and metacarpophalangeal joints contributed to rotation of the thumb.

Complex models for animating synthetic actors
TL;DR: A classification of models for animating synthetic actors is proposed based on the motion control method used and the type of actor interaction and these interactions give rise to a classification array with four rows and three columns.
