Inputs with multimodal information provide more natural ways to interact with virtual 3D environment. An emerging technique that integrates gaze modulated pointing with mid-air gesture control enables fast target acquisition and rich control expressions. The performance of this technique relies on the eye tracking accuracy which is not comparable with the traditional pointing techniques (e.g., mouse)...
Interactive animation generation is an attractive area of research for current animation developers in the field of virtual reality. As an essential tool for solving problems in many research areas, using standardized and structured terminologies, an ontological analysis could concisely describe the core logic of complex systems at a high level and facilitate system design. We propose a semantic framework...
Novel advanced game techniques provide us with new possibilities to mimic a complicated training process, with the benefit of safety enhancement. In this paper, we design and implement a 3D game which imitates the lifeboat launching process. Lifeboat launching is such a complex but vital process which can on one side saving people's life on sea and on the other side associating many potential hazards...

Using avatars in storytelling to assist narration has proved to be beneficial on promoting creativity, collaboration and intimacy among young children. Development of novel Human Computer Interaction (HCI) techniques provides us with new possibilities to explore the training aspects of storytelling by creating new ways of interaction. In this paper, we design and develop a novel digital puppetry storytelling...
3D modeling is an intricate and laboriously process which requires considerable investment of time to master. Researchers have long pondered on creating systems that would automate the steps followed by skilled 3D artists to generate detailed and realistic 3D models. Sketch Based Modeling (SBM) is a very broad area within the field of Computer Science spanning several sub-fields such as Computational...
We propose an energy-based method for dissolution simulation. Both the fluid (solvent) and solid (solute) are presented by particles. The dissolution priority of solute particles is based on the kinetic activation energy. The position of solute is determined using rigid body dynamics. We demonstrate plausible dissolving behaviours by using examples.
3D objects play a vital role in computer games, movies, TV, engineering design, and biological sciences. Researchers have studied 3D object retrieval techniques using 2D and 3D shape descriptors in the last several decades. In this paper, some of the most popular shape descriptors are reviewed. We first discuss the important criteria for a good shape descriptor. Then, we classify 2D and 3D shape descriptors...
