Human embodiment/representation in virtual environments (VEs) similarly to the human body in real life is endowed with multimodal input/output capabilities that convey multiform messages enabling communication, interaction and collaboration in VEs. This paper assesses how effectively different types of virtual human (VH) artefacts enable smooth communication and interaction in VEs. With special focus on the REal and Virtual Engagement In Realistic Immersive Environments (REVERIE) multi-modal immersive system prototype, a research project funded by the European Commission Seventh Framework Programme (FP7/2007(FP7/ -2013, the paper evaluates the effectiveness of REVERIE VH representation on the foregoing issues based on two specifically designed use cases and through the lens of a set of design guidelines generated by previous extensive empirical user-centred research. The impact of REVERIE VH representations on the quality of user experience (UX) is evaluated through field trials. The output of the current study proposes directions for improving human

“…Kanav Kahol [12] proposes that using sensitivity cue to convey the part's effective information, such as size, shape, texture and material. Fons Kuijk and Konstantions C [13] constructed the agents in a virtual environment and make them like human being perceive and communication. Inspired by agent, we make our virtual hand become the agent and which have perceive and grasping in assembly system.…”

Abstract-This paper introduces a method of constructing autonomous virtual hand in virtual assembly environments. The goal of this research is presented to improve the practicability of virtual hand in virtual environments. The autonomous virtual hand is realized as the agent by three steps. A gesture set of virtual hand is constructed. Initial gesture, basic gesture and grasping gestures help virtual hand to achieve autonomous grasping. Perceptional ring is constructed for virtual hand, which support the autonomous virtual hand sense the virtual object. The system divides autonomous grasping process into three perception stages. By using this method, user heavy load will be greatly reduced in the assembly process. We prove that this autonomous grasping behavior of flexible virtual hand has a good availability and efficiency.

REVERIE's Speech Recognition functionality supplies information on spoken input and User Affect Analysis functionality supplies head nod/shake input [8]. REVERIE's Reasoning Framework provides the control functionality for Simon [9].…”

Abstract-REVERIE (REal and Virtual Engagement inRealistic Immersive Environments) [1] is a multimedia and multimodal framework, which supports the creation of immersive games. The framework supports the creation of games integrating technologies such as 3D spatial audio, detection of the player's body movement using Kinect and WIMO sensors, NPCs (Non-Playable Characters) with advanced AI capabilities featuring various levels of representation and gameplay into an immersive 3D environment. A demonstration game was developed for REVERIE, which is an adapted version of the popular Simon Says game. In the REVERIE version, a player tries to follow physical instructions issued by two autonomous agents with different degrees of realism. If a player follows a physical instruction correctly, they are awarded one point. If not, they are deducted one point. This paper presents a technical overview of the game technologies integrated in the Simon Says demo and its evaluation by players with variable computer literacy skills. Finally the potential of REVERIE as an immersive framework for gaming is discussed, followed by recommendations for improvements in future versions of the framework.
