| Today's browsers (Mosaic, Netscape) were developed from the perspective of static hypertext services and they need new design ideas to scale towards WebWindows and televirtuality. In particular, on-board content authoring tools are urgently needed. |
| If WebWindows is to be useful for R&D and education, the current open Internet surfing needs to be augmented by a more organized and controlled navigation tools . Virtual Reality offers natural spatial organization metaphor and is coming quickly to the Internet via VRML. A natural strategy is therefore to add spatial dimensions to current in-time-only Internet surfing model. |
| To support the concept of active spaces in such televirtual collaboratory environments, virtual space management tools are required so that participants, not computers are in control. |
| In NPAC WebTools, we restrict ourselves to hypertext spaces and current Web technologies, and we prototype these three key concepts of the WebWindows technologies to come. |
