well, that definately is possible, but the whole thing that's awesome about the whiteboard, is that you dont have to hold the wiimote anymore. You just need to have an IR pen, that's it;)

I'm currently using the WiiRemote as a remote mouse, but only because i'm still waiting for my IR parts (using candles for the IR tracking, but i'm not gonna put those on my head or pen) so i can use it as whiteboard & headtracking as well Sad

Using it just as an wireless pointer/mouse works perfectly for watching movies & pictures on the bigscreen Smiley

In case it escaped your attention, there is a new set of controlers coming out for the wii (read: 3rd Party). The wireless nunchuck is coming... with two buttons on it... one for left, and one for right clicks...

Ok, Ive been reading through all the posts and maybe I am mis-understanding something, but wouldnt the easiest way to get a right click just to be with another led. No flashing or anything like that but essentially you just need two IR pens or just a second led somewhere. The wiimote just sees dots of IR light right? So if it sees one dot its a left click if it sees two its a right click?

I think thats pretty simple and I don't see why it wouldn't work.

Hello, ALL
Please I am new to the Forum & found the project very interseting. Though I have not went through the code or tried the WhiteBoard application. I have a small question.
== How the left mouse click is trigerred via IR pen?, Is it Always pressed or when Push Button on the pen is pressed triggers the Left Click.

Thanks in advance for the response.

push button triggers the left click.
@Thisisjon: Most pens that have been made so far did prove it's not that handy the way you describe it. The wiimote picks up 2 IR blobs when you're holding the pen at certain angles. That would mean unexpected/wanted clicks. That's why everyone is talking about this flashing;)

it is by default. you can change the behavior but that is one of the most talked about topics on the board is figuring out a good way to do clicks in a controlled manor. I personally have altered the software as demonstrated in my youtube video of a box you simply mouse over to change the behavior from right click to left click to move only but there are many great and ambitious ideas on here.

Would there be a way to eliminate getting multiple signals from a single LED? Because the idea of this is simplicity right? Having to get a blinking led that blinks at a certain speed at certain times doesnt seem simple to me, fun to mess with sure, but not simple. I would think a filter or higher powered LED would help eliminate getting multiple signals.

High Power LEDs won't solve the problem either.
If the distance between surface and ir-pen is too great then there will be two ir dots.
One is the reflection on the surface and the other on from the led.

I'm using a tap and hold function as rightclick but it is very buggy because I'm not a very good programmer.

how about this for an idea (it is more hardware based but might still work):
NOTE: this is all theory as i have not tested it yet.  i am just putting the idea out there

take a mini mouse like the ones people use for their laptop while travelling take out the board(s) and insert them into a largish marker case. you would need to remove the LED that is used for tracking replace it with an IR LED and move it to the tip. with a little further modification you can have all of your standard mouse buttons (Left, Right, and Middle Wheel) all at your finger tips on the pen. this way the plug and play drivers for most all mice and even the specific drivers for the mouse you use can control Left Click, Right Click, and even Scroll Wheel. From here all that is needed is a modification of atomriot's program that only moves the cursor.

as i have not tested this yet i do not know how well this will work and the biggest problem i forsee will come from calibration (although this also stems from the fact that all of what i stated is theory as i have not yet used any of the software yet) because what i have seen so far is that you have to blink the LED ad each of the four points.

for anyone worried about the cost increase of using this idea here are estimated increases in the cost of the pen based on the type of mouse you use (all refer to mini mice):

wired: ~$5-$10
RF wireless: ~$10-$20
Bluetooth: ~$20-$50

these cost increases also depend on where you get the mouse from


please give feedback on what you think the feasiblity of this idea is and possible improvements or major problems.

thank you

This idea makes the most sense to me.  It seems much easier to modify the way you hold the pen than to modify a wireless mouse or program a microchip. (e.g. I hold the pen with my right hand, so i'll place the wiimote on the left side of me.  One LED on each end of the pen should give plenty of space between the two, right? like in the finger tracking video?)

But how would the software know wich LED to track?

I like the brainstorming session here guys. (thumbup)  Smiley

Ok, I'm new to the WiiMote Project and this was possibly mentioned before, but couldn't you just do the following, without the need of a micro controller and with 1 single LED:
Just wire your Pen with parallel 2 circuits and two buttons (one for activating each circuit).
- Circuit 1 just lights the LED as usual (Left Click)
- Circuit two lights the LED though a RLC-Circuit:
http://en.wikipedia.org/wiki/RLC_circuit
With the right dimension of the components, wouldn't one basically be able to achieve an AC current in the 50Hz range?
Then the LED would only light with each "up" wave, and thus be blinking with 50Hz as desired ...
 I don't know if it would work and I can only try it in about 1-2 weeks as I'm busy with exams atm. (As an electrical engineering student this idea just sprung my mind ...)

If I'm talking serious BS here, feel free to correct me ...

My other approach would be to use one LED ont he tip of the pen and one on the back and do this 2 point-identification stuff. I guess both LEDs wouldn't be covered and would be spaced the right distance of each other, not to be mistaken as one blob of light.

I am new here and just read through this post.  If one is concerned about the complexity of programming a pic microcontroller, one option is to use the arduino - which has a usb interface and several i/o ports for various sensors and I have found quite easy to program (no special tools required). 

If people are suggesting the microcontroller to generate the flash then you could put the arduino in a box with a battery pack in your pocket and have a small wire connecting to the pen (as in Jimmy's video).  If you need the microcontroller to pickup the flashing signal then one could have the sensors mounted next to the wiimote and have it pick up the flashing and send a signal to the program through a usb port.

Im not into programming c+ at all so my best try into this right/left click will be to attach the insides of a 10€ wireless mouse to the back of a pen.
It sure isnt going to look pretty but it solves the battery case problem and clicking all at once. And the PIC/arduino solutions would be bulkier I think.
Will post some pics when im done with it if anyones interested.

(hope you c+ guys come up with some sleek double led solution...great discussion here)
