## But when will it happen???

## Early Users will be Frustrated

**Human interfaces are immature**
**Applications are not cross-platform**
**Applications are not inter-operable**
**Functionality is too narrow or the performance is too poor**

## Current Tools for Collaboration

**Same-time (synchronous) collaboration**
**face-to-face vision (desktop video conf.)**
**common scratch pad (whiteboard)**
**application sharing (shared X, Timbuktu, ---- )**
**Different-time (asynchronous) collaboration**
**posting and retrieving documents (email, --- )**
**application sharing (annotator, ----)**

## State-of-the-art forDesktop Video Conferencing

- Proprietary solutions are available
- not cross platform
- not interoperable
- Standards have been created for cross platform interoperable solutions
- H.320 for ISDN
- H.323 for Internet
- H.324 for POTS (Plain ordinary telephone)
- Vendors are claiming to have products soon that adhere to the standards

## State-of-the-art forWhiteboards

- Proprietary solutions are available
- not cross platform
- not interoperable
- Standards have been created for cross platform interoperable solutions
- T.120
- Vendors are claiming to have products soon that adhere to the standards

## Predictions for the Future

## Predictions for the Future

**First, VRML will attract a “critical mass” of users to 3D graphics on the Internet, and 3D hardware will become commonplace**
