I try placing the wiimote so that the wiimote can see the entire screen, but I always get 60 to 70% utility rate. How to improve it to become at least 85% utility rate.

And also, everytime I try to drag the mouse, it seems like it automatically double click it, and it will drag a box and select mulitple desktop item, how to solve this problem?

I using johnny chung Lee latest version source code. Hope I can get as much help as possible. Thank You!

James

Upgrade to boonjins app.
www.boonjin.com/wp

He has fixed all of Johnny's bugs and add heaps of awesome functionality. Most importantly a visual calibration assistant.

Most users stoped using Johnny's program a long time ago. JCL only released it as a demonstration of how the wiimote can be hacked, not as end user software. The second version was released because there where too many bugs in the first for it to even be a demo version.

Boonjin has done some amazing work developing Johhny's demo app out of sight and is only 1 or 2 alpha releases of going very stable beta.

Try Boonjin's app then post problems, you won't get much support for Johnny's as we will just tell you to upgrade to Boonjin's (or Uwe's Java if a Mac user).

Your tracking utilization won't get much better than 75% unless really lucky or using Boonjin's calibration assistant and calibrating 5 or 6 times. A tracking utilization of more the 60% is awesome and should not pose any problems.

Boonjin's smoothing function should solve your drag/click problems. Unless this is associated with a low quality IR-Led, which one are you using?

o ok thanks very much ben at first i though it was my IR pen problem, now u have help me clear my question on y i couldnt get more than 75% utilization from johnny program. I using johnny program is because besides making the whiteboard work effectively, i also nid to understand the logic behind it. But boon jin work does not include source code. But I will still try boon jin work to see how the perfect white board works!

Thank ben thanks alot :)

one more thing, sometimes, even my wiimote at the same place and all the setting are the same, but when i do the calibration, the utility percentage is always different. y is that so? it it because of the lights that are affecting it?

Another matter, every time i do calibration, sometime i need to cover the IR pen tip in order to calibrate if not the calibration point will jump to the bottom before i even touch the top right of the calibration point.

is the problem lies with my IR pen? or johnny lee program is like this? cause i saw johnny lee video, when he do calibration is like so simple and easy to get it done. So i was wondering why is it different from mine.

Hope someone can help me solve my problems

Thank you sooo much :)

James

Both are proberbly connected. Two potential problems 1: Other IR light source, could be from sun light or other device in the room. 2: You may have a poor connection or switch problem, this can be checked by using your mobile phone camera which is IR sensitive, see if any additional IR sources.

There will always be a slight variation between calibrations (1-2%) but anything more is a problem with your calibration.

Try in a totally dark room, use camera to check no IR-Pen problems and no other IR sources in room. You should get same tracking utilization give or take 1-2%.

JamesKL,
If you are aiming the wiimote at your computer screen, then the LED's for the power/bluetooth/wi-fi will interfere with your pen.  You need to cover them up with something the infrared light cannot permeate through.  But be careful, because some things such as tape will still let light through and continue interfering with the pen and therefore your initial calibration.

Thanks Benpaddlejones and jmatson

One more question is there any difference using a CRT monitor and a LCD monitor to test the whiteboard?

CRT: depending how flat will cause issues as adding a third dimension, also has static issues with pen (from experience).
LCD: best but watch for scratching, I suggest a screen protector for longterm use.
