Welcome in the “Second world” by Ludmila Martinicka

At a demonstration of new position-tracking system in Tokyo, Katsonuri Tanaka fixed the Web camera to his hip, stood in front of the mat printed with colorful codes and showed to a breathless audience new star on the sky of technologies. People could see the 3-D version of his avatar. As he was moving, scene on the mat was changing. Welcome in the second world, virtual reality. It is a fact, that the first and second reality are just one step away from each other. Tokyo university developed new position & tracking system. It uses a mat printed with colorful codes and ordinary web camera, which calculates the position of the user in three dimensions. As the user moves, the patterns on the mat are changing according to camera's perspective. Gaming in new position & tracking system makes maneuvering easier. All the moves are more like in the real life and brings to the player bigger experience and pleasure from the game. Player can try things which are not possible in the real world without giving his own life in the risk. Older games were facing problems with coordination of the characters and objects. In three dimensional system player can not cross objects like walls, cars, etc. (if it isn't purpose of the game). The system brings new way of interactive virtual experience. More than 11 million users are on line registered on the virtual universe, "Second life". Users can design their own characters, party together, go shopping, meet and chat... Just like in a real world. But to navigate an on line world is far from being easy.
