The screen is going to be curved, so we need a way do digitally manipulate the lens distortion.

@circleb I am suggesting you may get better results with an amorphic lens.  It depends if you have a regular curve or not, but may yield better results than digital alterations. (Or at least cheaper)

There isn't a need for 3D mapping, the projectors will be mounted above the screen, so we'll need to correct for distortion.

Could you elaborate on te triggering system? What does it trigger? Just the next slide or transition?

@Bart Arondson as far as the trigger, what we want is a way to start the presentation when someone enters the room. It might mean that the presentation starts when a door is opened, or someone passes a sensor.

Ah I see. Isn't it easier to just have someone press the button when someone enters the room without fiddling with sensors? Of course it would be nice if it would work, but I would consider it more as a bonus.

@Bart Arondson It's absolutely a bonus! I'd just wanted to through it out, because it would be very nice...

# Multi Projector Setup

Has anybody had experience with Multi Projector setups? I've been looking around and run across several options:

The only type of presenting I've done is with a single [Panasonic PT-D6000US](http://www.panasonic.com/business/projectors/PT-D6000US.asp), we want to branchout and do a really wide screen show. It will not be for a live performance (it seems like that is a big feature with most of those applications).
