In this paper, we introduce a novel real-time, interactive animation system which uses real-time motion inputs from low-cost motion-sensing device Kinect. Our generates interaction motions between the user character and counterpart in real-time. While of is generated mimicking user’s input motion, other character’s decided to react avatar’s motion. During pre-processing step, our analyzes refer...

the work presented here is aimed at introducing a virtual human controller in a virtual prototyping framework. After a brief introduction describing the problem solved in the paper, we describe the interest as for digital humans in the context of concurrent engineering. This leads us to draw a control architecture enabling to drive virtual humans in a realtime immersed way, and to interact with...

Creating a virtual character that exhibits realistic physical behaviors requires a rich set of animations. To mimic the variety as well as the subtlety of human behavior, we may need to animate not only a wide range of behaviors but also variations of the same type of behavior influenced by the environment and the state of the character, including the emotional and physiological state. A genera...

In this paper, we propose a new approach for generating interactive behaviours for virtual characters, namely the windowed Viterbi algorithm, capable of doing so in real-time. Consequently, we compare the performance of the standard Viterbi algorithm and the windowed Viterbi algorithm within our system. Our system tracks and analyses the behaviour of a real person in video input and produces a ...

With the recent introduction of realistic human entities into large-scale networked virtual environments, there exists a requirement for dynamic, real-time human motion. The future for distributed virtual environments will include upwards of 100,000 participants capable of participating from anywhere in the world, interacting with any entity that exists in the environment. In order to attain a ...

Probabilistic principal component analysis (PPCA) seeks a low dimensional representation of a data set in the presence of independent spherical Gaussian noise. The maximum likelihood solution for the model is an eigenvalue problem on the sample covariance matrix. In this paper we consider the situation where the data variance is already partially explained by other factors, for example sparse c...

An immersive virtual reality environment (IVE) for performing assembly and maintenance simulations has been developed using the Jack software package. The Flock of BirdsTM motion tracking system is used to capture body postures of an immersed human and reproduce it in real-time in the virtual environment. The CybergloveTM is used to capture finger movements in real-time for realistic grasp inte...

Motion capture, a currently active research area, needs estimation of the pose of the subject. This requires a match between a model and the 3D shape, constructed using a multiview system. Our purpose is to realize it in real-time, using the tree representation of the skeleton of the 3D shape. In this paper, we propose a new alignment distance between both rooted and unrooted weighted trees, ta...
