Video Chat Via Transparent Desktop Overlay
Jason0x21 writes "Wired News has an article about UNC Comp. Sci. researchers developing a transparent desktop overlay for video conferencing, allowing remote coworkers to literally point and interact with things on your screen. The researchers say that Apple's Quartz graphics engine let them go from idea to prototype in 'about 45 minutes'. Windows versions predicted in the future."
One of my favorite pieces of technology I've ever gotten a chance to play with is the SmartBoard Interactive Whiteboard It's a whiteboard that's touch-sensative. Basically, combine it with your favorite projection monitor and you've got a 60 inch touchscreen monitor. Just like any other touch screen, anywhere you tap the board is treated like a mouseclick in whatever application you're using. As an added bonus, "magic crayons" (really nothing more than plastic styluses) are at the bottom of the board. When the board detects one of the pens removed from its holder, it treats all touches as requests to draw on the screen.

It's a great presentation tool to liven up a powerpoint and avoid the need to have to walk accross the room to get the next frame. Furthermore, playing solitare with foot-high cards is quite fun.
From limited testing it seems that when a window is marked transparent in windows, it is composited into the display. But otherwise everything is non-compositing. This, in my experience, causes huge problems when fully opaque, non-layered windows are set atop a transparent one. Windows will often draw the old image while dragging the transparent window.
This is especially noticeable if you make a window transparent, then open the Task Manager (always on top) and drag the transparent window around. Very ugly..
And I haven't seen any way to make specific controls on Windows transparent alone or the window transparent alone (and leaving the controls opaque.
I had an internship at DoE lab outside of Chicago, Argonne Natl. Laboratory, at which we worked on a project similar to this. The system allowed multiple users (of various geographic, or digital distances) to connect to a Desktop Server, on which all users could interact with icons, windows and programs in tandem as if they interfacing with a local deskptop in windows. Althou, we used BeOS as our platform because it had a small footprint. Interesting that three years later private companies have out-done the DoE's work. Sad.
Business to business relationships have already become so depersonalised. This is just the next logical step - advancing technology that allows people to sit on their chairs to help other people. Heaven forbid that you would have to get up from your desk to help somebody!
Perhaps this kind of überchatting software is THE place where they can use those 3D desktop environments / window managers.
I don't really know if it would be useful, but perhaps it is cool to lean a window so you can see your partner while keeping an eye on the app content.
Anyway, beeing so far from the world as *I* am (yep, there are places on the south of the globe), where the bandwidth is kinda expensive, i can tell that i'll not be using this kind of technology for a while...
