Can someone tell me where I can get Johnny Lee's Automatic Projector Calibration from?

1. I need to make what he does for the hardware - are there any detailed instructions for this?

2. I assume he's using some software to the do the magic?

I can't come across ny downloads for software or anything else apart from the demo video?



Wiimote Smoothboard / Wiimote Smoothboard - mouse loses position gradually
« on: November 21, 2008, 01:36:18 PM »
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?



Johnny Lee's invention: amazing

But... erm... surely it must be able to create something much simpler?
(But with less accuracy)

Have a look at
This is a nice cost effective contraption
It relies on 2 beams beamed at right angles and hey presto you can turn ANY surface into a touchscreen surface

It suffers from the rubbish whiteboard touchscreen syndrome: you have to use their software + 4 coloured pens (from what I can see).

I thought it would be really easy to have 2 sides
2 sides, one vertical and one horizontal
With both emitting infrared beams

When someone disturbs the somewhere inside, the exact location can be worked out
Add a little coding and you can have this interaction be the mouse
And: you have a touchscreen surface

See the attached image for what I mean

Surely someone must have tried this?

OK... so maybe the accuracy of the touchscreen won't be the same, it might be something like 100dpi
BUT: that would be perfectly OK if you're not planning on writing with the application and using as a windows interface

AND instead if you plan to build applications that have big buttons
For example for building software for young kids to interact with
Or may the outside of shop windows where the user will be using their fingers to press onto the window

The great thing is the 2 sides could be discretely hidden away and the user wouldn't see this

Does anyone understand what I'm talking about!!?

Please reply! :)



Wiimote Interactive Whiteboard / Where can I get the source code from?
« on: November 19, 2008, 07:32:16 PM »
I assume Johnny Lee's code is freely available
But JoonBin's isn't?
From what I have read, JoonBin has made some big enhancements from the original?
I'd like to make and add a few alterations.

If I can't get JoonBin's code... can I get Johnny Lee's code + smoothing code and make something as good as JoonBin's?
(I think I've read on JoonBin's website that he got the smoothing code from somewhere else?)



When using a projector, how do I get a uniform screen when projecting at an angle?

(OK: not exactly a direct wiimote question... but I though I'd ask... as I assumed there would be plenty of experts on this forum)

I always end up with a wonky rectangle
OK: I don't have a huge amount of experience

Any replies would be great!



Has anyone tried whiteboard with a rear projection screen?

I think the answer is yes! :)
I thought I'd ask anyway!

I've seen one or 2 videos where someone has projected from below and is using the whiteboard
So I assume this is being done as I'm suggesting, i.e. with a rear projection

But, I haven't seen this done well anywhere

What would be great: projecting onto a transparent projection screen and using the touch screen in front of the screen

You could have the wiimote behind the screen - which would be brilliant as it wouldn't get in the way of anything and you could have it positioned so that it's in the best most optimal position

I'm not sure if there would be any problems if the wiimote is placed behind?

I'll be doing EXACTLY the above very soon - just waiting to get a few parts together
It will be another week or 2 before I have everything ready

Would be great to know if someone has done it already?
I'd like to see a video or 2



Wiimote Interactive Whiteboard / Whiteboard trouble with multiple monitors
« on: November 08, 2008, 07:16:35 PM »
I'm having trouble with JoonBin's whiteborad and using on multiple monitors

(I've trie searching the forums for 'multiple monitors' but there's only one thread on the subject)

My PC has 2 monitors

I know that the application doesn't support multiple monitors

All I want to do is have the touch screen be only on one monitor

Problem: it just doesn't work

Instead, I have to just use one monitor

Is it possible to have 2 or more monitors as your screen space and us ONLY one of the screens for the touch screen?

I've tried choosing to use just a selected area, but still no luck

Not sure if relevant, but my monitors are of different sizes - one is 17" and the other is 15"



I'm using JoonBin's amazing whiteboard software

One of the measures is the 'tracking utilisation'
What is this?
I'm assuming: the hogher the value I get for this, the better the tracking?

I've got my Wiimot 2.5m high up and I'm getting 5% tracking utilisation
BUT: in terms of tracking... it still seems to be really good

Assuming the bigger the number for this, the better: how do I get near the maximum?



I've tried and failed using a Belkin adapter
It kept asking me for a passcode
I've tried 0000 and 1234, neither worked
Is there anything else I should try?

Should it ask me for a passcode?
The instructions I've seen for bluesoleil don't give any reference to a passcode

I'm reading more instructions on how to try and make work with Wilcomm
But if all else fails: can I just buy ANY bluetooth adapter from eBay?
They're very cheap
I've tried searching for ones with 'bluesoleil' in, but there aren't any matches

The ones off the bluesoleil website are about 4 times more expensive
Can anyone give advice if I can buy any old one from eBay?
Or are there specific models I need to watch out for?
