Nope any projector will do (depending on light conditions) but as desk mounted one will require you to really think about your presnetation position. A short through is big $$$ a long throw on adesk is $ and a ceiling mount long throw is $$ which is a nice compremise.

For ultimate Wiimote location please read: http://www.boonjin.com/smoothboard/index.php?title=Mount_and_position_the_Wiimote

I am talking about the shadow that the projector is doing when u r sitting in front of the smart board.

The projector light is coming on u and its making a shadow behind u.

That, theoritically THIS PROBLEM is trying to solve the short throw projector, ceiling one. (most of them are can be installed on ceiling)

I am talking about this problem. Short throw any good or not... Because as u said, i loose in money. I will take it ONLY if its solving this problem.

this one i showed u, it can give 120ich projection image from 2 metres!

Hi,

A short throw projector will solve some of the shadow problem but it will be more costly.

Also, the Wiimote's field of view is still fixed. Therefore, the Wiimote will have to be placed further away compared to the position of the short throw projector. On a normal setup, the Wiimote's position will be roughly at the same position with the projector (for ordinary non short throw projectors).

Like I have mentioned in the personal message, you can use two Wiimotes simultaneously. This will allow you to place the Wiimote closer to the screen and possibly at a distance near to the short throw projector.

Regards,
Boon Jin

Why i have to place 2 Wiimotes in the place close to short throw projector? Why i cant place the Wiimote 1,5-2 metres away behind the short throw projector (as it recomended for this projectors) and use a remote sync power to activate it? whats the problem?

Example... Lets say i have a 120 inch screen 1,7m height 2.30 width. The short throw can project at 2 metres so i will place it on ceiling at this distance. The wiimote must be placed according to your guide to 3.4 metres. So it will be placed behind the short throw projector, on the ceiling, str8 ahead from screen.

If the projector blocks the wiimote field, it can be moved to the right ot left, at the same distance. (3.4 metres)

How is my idea? working ? 8)

I use an ultra short throw projector (Benq) ceiling mounted and about 1 metre from a 1.2m * 1.8m screen. The Wiiremote is ceiling mounted some distance behind and off set from the projector and it works extremely well without any shadowing. I also use a Greg Klein Quick USB switch to connect the Smooth Board software to the Wii.  Sure the projector is expensive, about $1200 Australian, but the total project price is still several orders of magnitude less than a commercial IWB and works just as well.
