Creating natural looking hair motion is considered to be one of the most difficult and time consuming challenges in CG animation. A detailed physics-based model is essential in creating convincing hair animation. However, hair animation created using detailed hair dynamics might not always be the result desired by creators. For this reason, a hair simulation system that is both detailed and edi...

In Virtual-Environment (VE) Applications, where virtual objects are presented in a head-mounted display, virtual images must be continuously stabilized in space against the user’s head motion. Latencies in head-motion compensation cause virtual objects to swim around instead of being stable in space. This results in an unnatural feel, disorientation, and simulation sickness in addition to error...

In CAVE-like environments human locomotion is significantly restricted due to physical space and configural constraints. Interaction techniques based upon stepping in place have been suggested as a way to simulate long range locomotion. We describe a new method for step detection and estimation of forward walking speed and direction in an immersive virtual environment. To calibrate our system a...

Generating natural-looking motion for virtual characters is a challenging research topic. It becomes even harder when adapting synthesized motion to interact with the environment. Current methods are tedious to use, computationally expensive and fail to capture natural looking features. These difficulties seem to suggest that artificial control techniques are inferior to their natural counterpa...

Convincingly animating virtual humans has become of great interest in many fields since recent years. In computer games for example, virtual humans often are the main characters. Failing to realistically animate them may wreck all previous efforts made to provide the player with an immersion feeling. At the same time, computer generated movies have become very popular and thus have increased th...

This paper presents an real-time interaction system which consists of human motion tracking using skin-colorbased Gaussian blobs and human motion synthesis based on real-time inverse kinematics. Our purpose is to do seamless mapping of human action in the real world into virtual environments. In general, virtual environment applications such as smart interaction require real-time human motion t...

In order to optimise the costs and time of design of the new products while improving their quality, concurrent engineering is based on the digital model of these products. However, in order to be able to avoid definitively physical model without loss of information, new tools must be available. Especially, a tool making it possible to check simply and quickly the maintainability of complex mec...

objectives: the gals (gait, arms, legs and spine) examination is a compact version of standard procedures used by rheumatologists to determine musculoskeletal disorders in patients. computerization of such a clinical procedure is necessary to ensure an objective evaluation. this article presents the first steps in such an approach by outlining a procedure to use motion analysis techniques as a ...
