MASSIVE-2 (a.k.a. CVE)

Complete re-write of MASSIVE

Extended spatial model

Improved navigation and interaction

Development platform

Scaleable multicast architecture

The extended spatial model

Focus and nimbus for direct awareness

Third parties for indirect awareness

• contextual/environmental effects
• scaleability

(Diagram shows objects A, B and T interacting with each other)

Effects of third party objects

(Diagram shows interaction between A and B through a third party. Communication from A to B can go directly, passing through 'adaptation', or via the third party, labelled as 'secondary sourcing'.)

Activating third party objects

membership

(Diagram shows A and B sending messages to the third party.)

sharing

(Diagram shows the third party sending messages to A and B.)

hybrid

(Diagram shows A sending a message to the third party, and the third party sending a message to B.)

General properties of third parties

Arbitrary shape and size

Medium specific

Mobile or static

Dynamically created and altered

May be applied recursively

Examples of third party objects

Crowds

• static and mobile
• membership and awareness driven

Regions

• boundaries with difference effects
• nested structures

Common foci

Vehicles

Network architecture

Each third party maps to one or more multicast addresses

Each artefact belongs to a local group

Dynamic world structure => dynamic multicast hierarchy

Multicast groups provide aggregate transmissions to their superiors

Special protocols for joining and leaving

Navigation and interaction

New controls and reset options

"Take me home" option

Escalators

Object centred navigation interface

Tracked (i.e. semi-immersive) interfaces

Selection of objects

Coming soon

Integrated video streams with spatial control
