One of the first tasks that people must do when entering a virtual world (VW) is create a virtual representation for themselves. In many VWs, this means creating an avatar that represents some desired appearance, whether a reflection of one’s real life self, or a different identity. We investigate the variety of ways in which people create and evolve avatar appearances in the VW of Second Life ...

Social judgments about other people are often made based on visual appearance. In this study, we investigated whether visual appearance of an interaction partner influences action coordination in social interactions. In a novel interactive augmented reality setup participants interacted (i.e. carried out a high-five) with a life-sized 3D avatar that was either humanlooking or robot-looking. Imp...

To enhance their reality, the shapes, textures, and colors of the avatars should be similar to those found in the real world. For a more realisti...

In his article "The Avatar as a Methodological Tool for an Embodied Exploration of Virtual Environments" Kris Pint proposes a theoretical framework for the analysis of environments which cannot be entered physically because they are fictional, inaccessible, or destroyed. As phenomenology has already emphasized, the analysis of space has to take into account the bodily involvement of the researc...

Computer and video games often requires that users, represented by characters (or avatars) on the screen, interact with other characters on the screen that either represent other real people or characters that are controlled by computer code running within the game (non player characters). The difference between game play with other avatars (player controlled characters) or agents (characters c...

Modern first-order resolution and superposition theorem provers use saturation algorithms to search for a refutation in clauses derivable from the input clauses. On hard problems, this search space often grows rapidly and performance degrades especially fast when long and heavy clauses are generated. One approach that has proved successful in taming the search space is splitting where clauses a...

The paper introduces a fast approach to prototype embedded systems. Software components are first modeled and formally verified using a SysML environment named AVATAR, supported by a free software named TTool. Simulation and formal verification of AVATAR components can be performed at the push of a button. The C/POSIX code of AVATAR components can also be generated directly from TTool. The gene...

The nonverbal communication can be used as a communication means between avatars having no common language in the Internet. Recently the sign language communication[1] system between avatars of different languages has been investigated as a means of overcoming the linguistic barrier. In this paper, we proposed an intelligent communications method, where sets of animations parameters such as the...

Persons who suffer from schizophrenia have difficulties in recognizing emotions in others' facial expressions, which affects their capabilities for social interaction and hinders their social integration. Photographic images have traditionally been used to explore emotion recognition impairments in schizophrenia patients, but they lack of the dynamism that is inherent to facial expressiveness. ...

Facial expressions of emotions are important in nonverbal communication. Although numerous neural structures have been identified to be involved in emotional face processing, the amygdala is thought to be a core moderator. While previous studies have relied on facial images of humans, the present study is concerned with the effect of computer-generated (avatar) emotional faces on amygdala activ...
