Visual Interaction and its applications
Intro:Visual interaction is a kind of technology that defines mechanisms, through which the users can perform actions on the interactive system by means of visual elements, and the system can provide feedback to the user, by visually representing the results of the computations triggered by the user actions. It continues to be both a hot academic topic in computer science, and a key factor in industrial, medical, entertainment and office applications, etc. To achieve a more natural communication with human in a virtual environment (VE), we require to detect or recognize human face, emotion, gesture, eye gaze, etc., and to efficiently render high quality images, so that people can interact through natural interfaces and receive prompt and realistic visual feedbacks. Researchers attempt to create natural user interface (NUI) for human-computer interaction that the user operates through intuitive actions related to natural, everyday human behavior. Thus, most research focuses on traditional human abilities, such as vision, touch, motion, as well as cognition and even expert skills to replicate real world environments to optimize interaction between physical and digital objects. In this special issue, we have selected 7 papers (research articles) covering 3 most relevant visual interaction techniques for the VE applications, including facial expression and gesture recognition, real time rendering, 3D manipulation.
