Eventually the DICE I-Room is likely to be located on a dedicated OpenSim region where a range of simplifications can be made. The initial DICE I-Room is placed at 500m above an unused area of the region (VCE in Second Life) to be clear of all distractions and other objects.
Initial Web-based Arrival, Setup, Resources and Registration
A single web page at a stable URL will provide everything needed in as short a form as possible. This will be more controllable in OpenSim, with custom simple starter avatars (perhaps basic male and female with self selected colored shirts, ethnic skin color and hair).

DICE I-Room Design

This page is a URL for a simplified 3D meeting space.. for experiments. At present it is by no means as it will look eventually.
