Global Positioning System

GPS or Global Positioning System is a location system designed to triangulate any point on the planetary surface, or in the skies above it.

It works via a receiver unit at the position to be checked, which has an internal clock, and a microwave receiver to receive signals from orbiting satellite or stratellite systems. The user does not have to transmit anything to the satellite and the satellite does not know the user is there.

The precise time delay for the clock tick of the microwave signal sent gives the distance to each satellite, with an error based on the accuracy of the receiver's clock.

By determining the position of, and distance to, at least three satellites, the receiver can compute its position using triangulation between them.

Local Area Augmentation Systems
A Local area Augmentation System is used to augment Global Positioning Systems when fine, precise detail is required. They could actually solve a lot more sensor web issues than just the use in aeronautics they have today.

Cities XL
Gameindustry.biz take a look at Cities XL, Monte Cristo's ambitious product, attempting to combine a traditional city-simulation game with massively multiplayer online functionality, giving players the option to take part in a global, entirely player-dependent global economy.

Mudding with Language Barriers
?In a global community, language has no limits and interpretation is sometimes misleading.?

'Stealth': A.I. out of control

An AI-based unmanned stealth fighter jet, after being hit by lightning, decides to execute a top-secret mission that could result in global thermonuclear war ? the plotline from Stealth, a movie based on reality?

The VRT Concept
One of the problems with global, persistent, shared virtual environments, is time. More specifically, time zones. To demonstrate this problem, go to any non-roleplay virtual environment or even a simple chatroom with a fair number of participants, and ask people what the time is:

Cells with double vision
Unlike in the peripheral nervous system, where cells are often unable to distinguish which branching pathway an electrical system is travelling from, the central nervous system makes use of sophisticated internal networks not too dissimilar from an IP record, to differentiate between nervous pathways.

Designing Virtual Reality Systems: The Structured Approach

This book is very much a holistic first-timer?s guide to creating a hideously complex system ? a full virtual reality. The book describes a VR system as ?a system that provides a synthetic experience for its user(s)?, a definition which could not possibly be any broader.

A Realistic Equipment System
One person?s take on creating an inventory system that emulates reality.

Virtual Manniquin - You!

Industry news, originally posted 02-02-2004, deemed too important to allow to fade. Tired of battling with wardrobe accessories in crampt changing rooms? Fed up of trying oh-so-carefully not to damage items whilst your body does its best to get in the way, and the stall is falling apart around you? VR may have a solution, in the form of a system developed by Toshiba. The company is developing a 3D, realtime system uses video cameras to create a virtual copy of your body on a screen, and not only moves with you, just as a mirror would, but also tries on clothes, without you having to. The system is still at an early stage, but it could in use in stores within three years.

Kluge: The Haphazard Construction of the Human Mind

The human brain is the ultimate legacy system, with bodges, klonks, workarounds and kludges forcing it to work as a (mostly) cohesive system.
