MASSIVE-1

(Model, Architecture and System for Spatial Interaction in Virtual Environments)

VR teleconferencing system

• Support for ~10 participants
• Client-Server unicast architecture
• Inplements "Spatial Model"

(Images show Adrian's embodiment within MASSIVE waving.)

Graphical, Textual and Audio media

Communication

• Audio via spoken voice
• Text via the text client for simple text chat, and the blackboards for more persistant messages

(Images show Adrian's embodiment within MASSIVE saying 'Yes' and 'No', and 'shrugging'.)

Embodiments supporting simple gestures

• Arm movement
• Sleeping
• Pointing

(Pictures show Adrian's embodiment in MASSIVE with arms pointing towards 'camera', and lying on its back 'asleep'.)

Limited Object Interaction

• Blackboards

(Picture shows Adrian's embodiment in MASSIVE looking at the blackboard.)

Worlds Interconnected by Portals

Navigation

• Graphical client uses the mouse
• Text Client uses the keyboard ("nethack") keys

Different camera angles

(Pictures show Adrian's embodiment doing various things in MASSIVE.)

Camera Andles

(Pictures show various camera angles on a scene within MASSIVE.)

The Trials

SuperJANET used for network connections between sites

MASSIVE softward distributed to all sites

A central server ran at Nottingham for all trials

(A map of the UK shows the positions of the sites: Lancaster, Leeds, Manchester, Nottingham, BT (on the East Anglian coast) and UCL.)

20 meetings

Between 4 and 10 people per meeting

18 different people

25 different worlds

Different Trial phases:

• configuration
• training
• stabilisation
• the main meetings

(Pictures show trial meetings within MASSIVE.)

What happened then?

• Group Games
• Find the clues and solve the puzzle
• Presentations
• A focus based task
• A Party!
• A Monty Python sketch

(Pictures show trial meetings within MASSIVE.)

And now a short video showing highlights from the trials...
