Project Overview
Telecollaboration is one of the NSF Science and Technology Center's main reseach areas and driving applications whose goal has been to develop a distributed collaborative design and prototyping environment in which researchers at geographically distributed sites can work together in real time on common projects.
At Brown, we are developing Jot, an offspring of
Sketch. The goal of Jot is to provide an end to end solution for the rapid production of mechanical parts in a collaborative
environment. Using Jot, the offspring to Sketch, an idea can be rapidly sketched on the Active Desk at Brown, and using
the Center's high speed televideo network, multiple people at other sites can suggest ideas for the improvement of the design. These ideas can then be incorporated into the design, and everyone's displays are updated to reflect the
changes.
After a rough sketch is produced, Jot then permits the user to parameterize the model thereby applying accurate measurements to the rough sketch. This parameterized model can then be exported to Utah's Alpha_1 system, which can generate NC (numerical control) code for machining the part.
