ReLaTe Integrated Interface - overview

The integrated interface, which brings together the audio, video and shared workspace tools, has been designed to be as simple and easy to use as possible. Particular emphasis has been given to reducing screen clutter and to minimising the number of things that need to be done to use the different parts of the software. There is minimal need to manipulate, move or uncover windows, and all necessary tools and controls are readily to hand. Although basic keyboard and mouse skills are required, little else is needed for students and teachers to use the software.

Currently, up to eight people can take part in a conference. As the screen-shot shows,each participant uses a workstation with camera and headset (headphones and microphones). Video images are displayed of all participants (including oneself), and any image may be enlarged to the upper window. Being able to see all members of the conference simultaneously gives a more relaxed atmosphere than other systems, which show only the current speaker.

The system incorporates both a shared whiteboard (wbd, by Julian Highfield) and a shared text editor (nte, by UCL). The user can switch between them at any point during the session. With these tools, text and graphics can be entered, either via the keyboard and mouse or by importing a file. Everyone can draw or write simultaneously and see all other contributions; colour allows easy identification of the contributions.


Download Software
The latest version of ReLaTe integrated interface can be downloaded from here. Please note that you should first install the following versions (or higher) of the mbone tools VIC2.8ucl3, RAT3.0.29, NTE1.5.31 and WBD1.0ucl2

A script is available to start the ReLaTe interface via the session directory tool, SDR. Download the script from here and place it in the SDR directory. After restarting SDR, it will be then possible to join conferences by using the ReLaTe button in the SDR Session Information Window. Thanks to Christoph Fleck for writing this script.


Documentation
Documentation for the ReLaTe integrated interface can be downloaded from the Software section of the UCL Multimedia web-page.
