I'm designing a presentation room where a customer gives a Prezi presentation, among other things. This presentation is sacrosanct, and an absolute non-negotiable in the new room design.

They want a single wireless device from which they can control everything in the room. We're using Creston CP3, so it's easy enough to switch lights, AV, etc. from a wireless touch screen. But I cannot find a way to advance the Prezi.

For those unfamiliar with Prezi, it's a web-based presentation software that...looks really pretty, basically. It has to run on a computer, and you have to advance it with a mouse/keyboard/PPT clicker. So I'm trying to find something that I can control from a Crestron CP3, but can plug into and emulate some sort of keyboard/mouse/PPT clicker to a computer.

Any ideas out there?

install Eventghost on the computer.  It can listen for TCP packets from the Crestron system and trigger keyboard shortcuts or mouse clicks.  You could even use a USB to serial adapter and trigger macros in Eventghost via RS232 commands from the Crestron if you like.
