Modeling Spatial-Temporal Context Information in Virtual Worlds

Currently, we use many definitions with diffuse boundaries Web 2 0 (Social Networks), Web 3 0 (Semantic Web); Web 3D (Metaverses, Virtual Worlds, Mirror Worlds); Recommendation Systems. Augmented Reality; Geo-location In tins paper we explore the possibilities of the combined use of these concepts, we introduce the concept of VARD (Virtual Augmented Reality Device) and show interoperability between recommendation systems and Virtual Worlds We have developed a Recommendation System which have two ways of interaction with the virtual world of Second Life in connection with context spatial-temporal information an active recommendation system called TESLAR, that interacts with avatars by a 2D HUD VARD object, and a passive and automatic recommendation system; called MarvinBot, that interacts with avatars by a Metabot VARD
