Wiimote Interactive Whiteboard / Re: PC Monitor = Touch Screen???
« on: June 28, 2008, 07:52:25 AM »
check out nui group.  They have been successfully experimenting with multitouch screens.  There did not seem to be much interest to pursue this approach on this forum.  Hope this helps

here is a link for a possible software calibration option, with a modified camera setup
they even have a forum

get a load of his calibration software, have you been able to track down this guy?

Interesting video.  Did you notice the cam corder on the inside of the table top, and the wiimote on the top of the table pointed outward.  I am wondering if he uses the camcorder for usual mouse tracking, and the wiimote for the minority report simulation.  Based on other prototypes that I have seen the IR camera is always under the table.  Does this make reasonable sense?

I've been thinking alot about interactive table top interfaces and found this link that may work with the wiimote setup:

From what I see, it looks like the current wiimote whiteboard setup could be compatible with this setup.  Any suggestions about modding the current software?  What do you all think?

IR Pens / Re: IR LEDs
« on: May 15, 2008, 02:27:22 PM »
I have had no success with radio shack LEDs.  I have found that using the vishay TSAL 6400's offer the best performance.  I guess it depends what you use it for.  I currently use it for a whiteboard setup and use a pen with 2 IR LEDs.  I find that this greatly improves tracking ease.  Wiimote placement is not as critical.  My suggestion is bite the bullet and pay the shipping.  I have found it is well worth the cost versus the wasted time and frustation.  Good luck

hello all,
I was hoping for some input on the feasibility of using the new wii fit with the wiimote whiteboard setup.  Specifically, using the edusim software with the directional controls controlled by the wii fit board.  While I still am waiting for the release, I am wondering if any US or Japan forum users have already started work on this possible mod.  Great forum and I welcome any ideas.

IR Pens / Re: The birth of "Big Motha"...

thanks for the great reply.  What would you suggest.  Should I run them in series, or parellel and have resistors?  Is there any disadvantage to not supplying the LEDs at full voltage.  Also, it was my understanding that it was the current that would burn them out not the voltage.  I have tested the 3 LED setup (with 3 AAA) and it seems to work better, than the single LED with a 30 ohm resistor.  I would appreciate any suggestions or advice.  The setup I am using is an LCD projector with the wiimote 6-7 feet away.  Thanks again.

I have tried this website but the schematic does not match my design.  I have the 3 LED's in series.  Also, I am assuming the voltage of the LED is 1.6 volts and the current is the forward current (100mA) and not the peak forward current (200mA).  Again, I am new to electronics and am unsure if I am putting in the right information.  Thanks for any assistance.

I am currently completing my 3 LED pen, with 3 AAA batteries.  The question that I have is: are any resistors needed to reduce the current flow?  I am new to electronics and would appreciate any help.  I am using the VISHAY TSAL 6400's.  While it is currently is working, I am afraid that the LED's may fry with frequent use.  Thanks

IR Pens / Re: 50mA versus 100mA
« on: March 05, 2008, 09:16:32 AM »
I am using it for the wii whiteboard.  Currently, I am not projecting using an LCD, and am using my laptop to test.  the Wiimote is is 3-4 feet away from the laptop screen.  I tried to model my setup as close to Johnny Lee's setup.  The light that shines from his pens seem much brighter, when he is doing the whiteboard demo on a table surface.  When I point my IR pen at the wiimote and press the momentary switch, numbers appear on Johnny Lee's calabration program.  The numbers do not appear when you are more than 3 feet away.  Thanks for any suggestions.

IR Pens / 50mA versus 100mA
« on: March 04, 2008, 10:27:49 PM »
I just completed my IR pen and it does not seem to work.  The specs on this LED are as follows:

5mm INFRA RED EMMITTING LED (KIE-7305-1P) radiant intensity-100mW/sr   1.6V @50mA

I am wondering if this LED is not strong enough as the one recommended by Johnny Lee (Vishay TSAL6400) is 100mA. Any help would be greatly appreciated as I am not good with electronics.  I have this LED hooked up to 2-AA batteries with a 30 ohm resister and a momentary switch.  Thanks for any help!
