Worlds chat

Worlds Chat is an on-line virtual reality based chat program introduced in April 1995 by the company Worlds Inc. and as of October 2017 is currently online. At the time of Worlds Chat's release, Worlds Inc. was in its second year of existence and already a leader in creating virtual workspace environment having created virtual meeting spaces for clients such as Sprint, Intel, and UB Networks. Worlds Chat was the first program they made available to the general public and it was offered free of charge for download from their website. The popularity of the program and Worlds Inc.'s other successes, such as Tamiko Thiel's work with Steven Spielberg to create Starbright World (a virtual world for seriously ill children), allowed Worlds Inc. to procure a minority investment of $5.6m from Pearson plc in June 1995.

The Worlds Chat user was allowed to choose from a gallery of existing three-dimensional avatars to be their representation in the virtual world. The gallery was presented in a fashion similar to that of a first person shooter, except without the hands and weapon in the viewport. Once an avatar was chosen, the user was placed in the central hub of a virtual space station. The user would see representations of other online users in the station. Users could exit a platform through sliding doors, travel through halls, and find other platforms with groups of people to interact with. The screen was split into several areas including one for messages from the software program itself, a window with a Doom (video game) like 3d interface, a window for chat messages, and a space station map indicating which platform the user currently inhabited. Both a keyboard and mouse were integral parts of the user interface.

Assembled by Dave Marvit (VP of Production), the original team that put together Worlds Chat consisted of Andrea Gallagher (producer), Dave Leahy, Syed Asif Hassan, and Bo Adler (development), and Jeff "Scamper" Robinson and Helen Cho (UI and graphics). The original client/server protocol for the multi-user environment was developed by Mitra Ardron, Bo Adler, Judy Challinger, and Dave Leahy (PTO US6219045). Unlike other immersive environments of its day, it worked on lines as slow as 9600 baud. Contributors to the project included David Tolley (music), Wolf Schmidt (documentation), John Navitsky and Scott Benson (operations), Naggi Asmar (quality assurance), and others.

The first release of VRML, a standard for defining virtual reality environments, was less than six months old when Worlds Chat was released. This meant that Worlds Inc. needed to discover and define its own best practices while creating Worlds Chat. The additional speed of dial-up Internet connections naturally placed limitations on the amount of information that could be transmitted to and from the Worlds Inc. servers. An increasing number of users and expanding virtual world increased these pressures.
