Previous studies using the dot perspective task have shown that adults are slower to verify the number of dots they can see in a picture when a human figure in the picture, an avatar, can see a different number of dots. This "self-consistency effect," which occurs even when the avatar's perspective is formally task-irrelevant, has been interpreted as evidence of implicit mentalizing; that human...

Avatars are pervasive in video games and virtual worlds. The automatic generation of these avatar promises to reduce player effort and provide system-defined mappings between “real” (physical) player characteristics and virtual identities. We present an avatar generation system called Exigent; given a photograph of a human face, Exigent creates an avatar. Exigent leverages two recent computer v...

We are interested in the way players identify with their virtual characters, and how this identification could be exploited to augment players’ cognitive abilities. Our approach is based on the cognitive neuroscience theory of common coding and related experiments, that suggest that perception, imagination and execution of movement are linked by a common representation in the brain. We report t...

This paper describes a method for automatically imitating a particular facial expression in an avatar through a hybrid Particle Swarm Optimization – Tabu Search algorithm. The muscular structures of the facial expressions are measured by Ekman and Friesen’s Facial Action Coding System (FACS). Using a neutral expression as a reference, the minute movements of the Action Units, used in FACS, are ...

Abstract This article presents a new use case of using handheld augmented reality to set up smartphone camera for taking self-photograph needed evaluating the user’s sports exercise. The problem addressed is that settings rear so users can take photographs themselves performing poses without need assistance from another person. proposed solution uses an avatar with same body properties as user,...

Abstract Background Since subjects with Rett syndrome (RTT) focus their attention mainly on the faces of people whom they interact, in this study role a human-like smart interactive agent (an avatar) enhancing cognitive processes is examined. More depth, aimed to understand if, and what extent, use an avatar can improve memory abilities RTT. Method Thirty-six RTT participated study. All partici...

An increasing number of our interactions are mediated through e-technologies. In order to enhance the human’s feeling of presence into these virtual environments, also known as telepresence, the individual is usually embodied into an avatar. The natural adaptation capabilities, underlain by the plasticity of the body schema, of the human being make a body ownership of the avatar possible, in wh...

Playing Multiplayer Online Role-Playing Games (MMORPGs) is now a popular leisure activity for some people. Players spend significant energy and money on it. In MMORPGs, players can customize their avatars as virtual identities to present themselves in the virtual world. Avatars are important when playing MMORPGs. However, few previous studies focus on the psychological determinates for avatar p...

Participants using immersive projection technology (IPT) systems tend to behave as if they were really in the space depicted by the displays. This behavioral presence leads them to adopt responses and strategies to events and situations that are similar to what they would adopt in analogous real-world situations. In this paper we discuss what happens when IPT systems are used for tele-collabora...

This paper reports an analysis on effect of text-to-speech (TTS) and avatar agent in evoking user’s user’s spontaneous backchannels. We construct an HMMbased dialogue-style TTS system that generates human-like cues that evoke users’ backchannels. We also constructed an avatar agent that can make several listener’s reactions. A spoken dialogue system for information navigation was implemented an...
