Making a Projector Interactive (retroactively)
This is one of those frustrating coincedences of timing that haunt me.
Back around Easter the incumbent Drama teacher asked if we could install a projector and big screen in the main Drama room to be used as a backdrop for productions, along with a fat (phat) pair of speakers. KPMS did us a lovely job of hooking up a short throw projector on the lighting rig and a 2m pull down screen that's already been used in some brilliant productions.
Last term they finally got round to interviewing for the permanent position and, for better or for worse, the current teacher didn't get it and we have a new head of drama coming in. She's asked about having an interactive whiteboard as she likes teaching with them.
Where the current projector is aiming is no use for fitting a smartboard as there are too many pipes & pillars in the way, and the image would be too big anyway given that the projector was chosen to give us the massive 2m image. The pull down screen can't move either as it's where it needs to be to act as a backdrop. I'm very reluctant to spend another £2k fitting an ultra-short throw above a smartboard on another wall as that's half my annual projector budget and there are plenty of other departments needing new/replacement kit, and with this room having just been fitted with exciting new kit it strikes me as rather unfair that it gets another bite of the apple within 6 months when other rooms are making do with godawful projectors or none at all.
So answer me this: how can I make the existing pull-down screen & projector combo interactive in the manner of a smartboard? Is there a way of fitting said functionality retroactively?
