As part of our work on a forthcoming white paper looking at the ever-growing range of 3D immersive environment platforms available we thought it would be useful to identify some criteria/function sets to help make comparison easier. If you were to use these as part of a selection exercise then you'd probably want to weight them appropriately as different use-cases would need different features. We've also assumed that all offer a common feature set, including multi-user and text/voice communications, walk/run, screengrabs etc.
A lot of these categories are quite encompassing, and a further analysis may split them down into sub-categories - or create more higher level categories where a particular feature becomes important. We may well revise this list as we work through the platforms (at least 25 at the current count) but here's our starter for 10 (in alphabetical order).
A/accessibility (with a lowercase a) and Usability
Avatar Fidelity & Customisation
Environment Fidelity and Flexibility
Meeting and Collaboration Functions
Object Rez, Build and Import
Open Source/Standards Based/Portability
Persistency/Shared World/In-World Creativity (World Fidelity?)
Privacy and Security
Scripting and Bots
