I've been using Wiimote Smoothboard and am finidng that the mouse loses position very quickly
Starting off: it will be spot on...
But then a few minutes later it will be a centremeter off from where my infrared pen is

Has anyone else experienced this?

Thanks

i'm a big fan of dry witty humour

details:

- projecting onto a pvc surface
- wiimote positioned at an angle 2ft above the height of the screen positioned 2ft left and pointing down

the setup i have been playing with is absolutely awesome: i'm projecting from the rear onto 4 surfaces
(these are speacial surfaces that you can use to rear project onto)
the surfeaces are attached to a transparent acrylic

when i have a proper setup, i'll make a video

let me know what you think

if this isn't a common problem, then maybe the problem was mine as the surface being projected onto wasn't secure

let me know what you think

what's an iwb?
i have to admit, i've been doing a lot of thinking about how to commercialise and sell consultancy all revolving around the wiimote touchscreens
i'd be interested to know what you're doing!

This happens to me all the time.  Every time someone shuts the door to my classroom, my wii-remote jiggles a little bit.  It's only a mm or so, but over 9ft that mm (like how I mix my customary and metric units?) is amplified into a good inch or so sometimes.  This happens almost as much with my real SMART board, but not as bad.

Ever since my school started buying SMART boards, I miss my smoothboard.

hmmm very interesting. i take it u are complaining about how it loses its accuracy?
i.e. when you touch the screen the mouse is an inch away?

not an expert (yet), but i'm pretty sure you can assign one of the outside areas to be a trigger to the recalibrate button for boonjin's application - so if you find it gets out of sync, just click on the outside, 4 more clicks... and you're repositioned back to normal

ben (or someone else), can you confirm the above suggestion is a good idea?
also... maybe we can ask boon to add it as an extra functionality so that maybe the whole screen doesn't go white and that after the 4th click the smoothboard application is not on top (does that make sense?)

Your idea of using the outside screen area for recalibration should be feasible. Will think through it and try it out. Thanks!

What do you mean about the whole screen doesn't go white?

The smoothboard is on top after calibration is also for the user to see the calibrated area. Is it very annoying?

I think that a "see through" or "transparent" calibration would be a great option! This way the calibration takes place without atrracting attention of the students/audience. I need to recalibrate regularly (due to shifts in the setup?).
