Virtual time and global states of distributed systems.

by Friedemann Mattern - Proc. Workshop on Parallel and Distributed Algorithms, , 1989
"... Abstract A distributed system can be characterized by the fact that the global state is distributed and that a common time base does not exist. However, the notion of time is an important concept in every day life of our decentralized \ r eal world" and helps to solve problems like getting a c ..."

Marker tracking and HMD calibration for a video-based augmented reality conferencing system

by Hirokazu Kato - in The 2nd International Workshop on Augmented Reality (IWAR 99 , 1999
"... We describe an augmented reality conferencing system which uses the overlay of virtual images on the real world. Remote collaborators are represented on Virtual Monitors which can be freely positioned about a user in space. Users can collaboratively view and interact with virtual objects using a sha ..."

Computing semantic relatedness using Wikipedia-based explicit semantic analysis

by Evgeniy Gabrilovich, Shaul Markovitch - In Proceedings of the 20th International Joint Conference on Artificial Intelligence , 2007
"... Computing semantic relatedness of natural language texts requires access to vast amounts of common-sense and domain-specific world knowledge. We propose Explicit Semantic Analysis (ESA), a novel method that represents the meaning of texts in a high-dimensional space of concepts derived from Wikipedi ..."

Mudding: Social phenomena in text-based virtual realities

by Pavel Curtis - IN PROCEEDINGS OF THE 1992 CONFERENCE ON THE DIRECTIONS AND IMPLICATIONS OF ADVANCED COMPUTING , 1992
"... A MUD (Multi-User Dungeon or, sometimes, Multi-User Dimension) is a network-accessible, multi-participant, user-extensible virtual reality whose user interface is entirely textual. Participants (usually called players) have the appearance of being situated in an artificially-constructed place that a ..."

Illusion and well-being: A social psychological perspective on mental health.

by Shelley E Taylor , Jonathon D Brown , Nancy Cantor , Edward Emery , Susan Fiske , Tony Green-Wald , Connie Hammen , Darrin Lehman , Chuck Mcclintock , Dick Nisbett , Lee Ross , Bill Swann , Joanne - Psychological Bulletin, , 1988
"... Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive selfevaluations, exaggerated perceptions of control or mastery, and unrealistic optimism are charac ..."

Supervisor

by Anna Cicognani, Dr. James Rutherford, Prof Mary, Lou Maher , 1998
"... In this research, it is suggested that design in text-based virtual worlds can be identified as a series of interactions between users and the virtual environment, and that these interactions for design can be approached using a linguistic perspective. The main assumption of this research is that a ..."

Supporting Trust in Virtual Communities

by Alfarez Abdul-Rahman , Stephen Hailes , 2000
"... At any given time, the stability of a community depends on the right balance of trust and distrust. Furthermore, we face information overload, increased uncertainty and risk taking as a prominent feature of modern living. As members of society, we cope with these complexities and uncertainties by re ..."

by relying trust, which is the basis of all social interactions. Although a small number of trust models have been proposed for the virtual medium, we find that they are largely impractical and artificial. In this paper we provide and discuss a trust model that is grounded in real-world social trust

Improv: A System for Scripting Interactive Actors in Virtual Worlds

by Ken Perlin, Athomas Goldberg , 1996
"... Improv is a system for the creation of real-time behavior-based animated actors. There have been several recent efforts to build network distributed autonomous agents. But in general these efforts do not focus on the author's view. To create rich interactive worlds inhabited by believable anima ..."

Evolving Virtual Creatures

by Karl Sims - in SIGGRAPH 94 Conference Proceedings, ser. Annual Conference Series , 1994
"... This paper describes a novel system for creating virtual creatures that move and behave in simulated three-dimensional physical worlds. The morphologies of creatures and the neural systems for controlling their muscle forces are both generated automatically using genetic algorithms. Different fitnes ..."

Evolving 3D morphology and behavior by competition

by Karl Sims - Proceedings of Artificial Life IV , 1994
"... This paper describes a system for the evolution and co-evolution of virtual creatures that compete in physically simulated three-dimensional worlds. Pairs of individuals enter one-on-one contests in which they contend to gain control of a common resource. The winners receive higher relative fitness ..."
