Wiimote Interactive Whiteboard / Re: MOUNTING
« on: March 08, 2009, 12:59:01 PM »
You might want to check out my post on universal wiimote mounts. Here are a couple of simple ways that look really clean to mount your wiimotes, yet not mar the surfaces you mount them to.

IR Pens / Re: backwards facing pen?
« on: March 08, 2009, 12:47:49 PM »
Dr Matt, have you thought of trying a side mounted LED? A year ago I built three pens with the side mounted leds described in my post linked below. The result is very good. The LED is facing 90 degrees closer to the wiimote, its still near the 'drawing' point, and it is a high output led. My tests had the wiimote out to 19' from the projected surface (although the wiimote loses resolution at that distance). I've now used this setup in front of clients at architectural reviews three times without fail.
You may also want to see my mini version and the summary of my pens...

BoonJin:

I just came back to your webpage and it looks like you've really been busy. I think it is terrific that you've worked with Jason Smith to integrate the presenter. I use both the whiteboard and the presenter programs separately at work and this integration will definitely help with setup time.

I have a new addition to suggest to the presenter program. Often times we have multiple presenters and a restricted time schedule for each presenter. It is too uncertain to setup the timer for wiimote to help control time. Can you set up a keyboard key that when tapped will buzz the wiimote? This could serve as a private buzz to the presenter from the person behind the laptop to say "Hey, your running long."

Thanks for your consideration.

Jason,
I used the presenter program at work yesterday and everyone was much impressed by the technology, although they weren't quite sure what the led throwie was all about. I just had a product improvement idea. Can you write into the code a way for someone sitting at the laptop to press a key and buzz the wiimote? This would be useful for our multi-person presentations to warn them silently about time overruns.Thanks.

I finally had a chance to use this pen in a real work presentation, well three presentations actually. I used it in conjuction with a powerpoint presentation and it's internal pen function. I used this pen to mark up floor plan changes requested by the clients in real time. It worked great. In fact, my Project manager originally thought I had used a red marker to mark on the client's wall. The look on his face was classic. It took forwarding to the next powerpoint slide to make him realize it was a digital markup. I also used my magnetic ceiling mount for the Wiimote.

I'm happy that after all this time I had a chance to use this stuff for a practical application.

Thanks for the second version Jason. I look forward to using it on a biz trip I'm going on starting tomorrow. Thanks for looking into the laser pointer idea. Your double command change will help me control view functions for the 3D program Sketchup.

IR Pens / Re: Meet Pixel - a small and clean LED pen
« on: May 31, 2008, 09:24:52 AM »
I glued a 1/4" nylon nut to the bottom of my Wiimote with gorliia glue. I let it set up overnight. Then, with the nut in place, I screw the wiimote on to a cheap 6" tall camera tripod (radioshack for 6bucks). I set the tripod with wiimote ontop on my desk pointing toward my lcd screen at about a 30-45 degree angle. I somtimes have to fiddle with the location so the wiimote can 'see' the full screen. With this pen I'll always set up the wiimote to my left. I just posted a couple pictures of the nut glued to the wiimote on my picasa paged that is linked in my first post above. Hope this helps.

I tested this out with my monitor today and it worked great. The detail was fine enough to draw with in Photoshop.

IR Pens / Meet Pixel - a small and clean LED pen
« on: May 26, 2008, 01:59:06 PM »
I wanted to share the second incarnation of my side-mounted LED pen. I always wanted to make a mini-LED pen for use at my desk since I started this crazy project in March.

I took a small laser pointer, cut off the laser diode, and then attached leads to the provided switch(negative end) and case (which carries the positive). Using a Vishay TSMF3710-GS08 surface mounted (SMT type) LED I was able to solder the leads coming out the end and fold the LED over to form the point. See pics below...

IR Pens / Re: What is the Wiimote's Preferred Peak Wavelength???
« on: May 25, 2008, 09:56:36 AM »
I appreciate the test of wavelengths inio. I can't say I have lab tested the wavelength pickup of the wiimote.

I can say that the 850 nm wavelength of the side-mounted LED's I've used work great even in the very bright lighting of our office conference room out to 19 feet.

So I wouldn't go so far as to say that 950 nm is the preferred wavelength for LED's. I will say that I wish I had a best practices guide like the one you just posted when I started this wiimote project a couple months ago.

Jason:

I tested out your wiimote presenter program with the IR LED throwie at work today. It worked great. In fact it gathered a number of oohs and aahs from neighboring cube mates (as well as myself). I can see now I will spending much of my free time playing with different configurations for both the wiimote and SketchUp to see what 'feels' the best with wiimote movements and buttons. I had a thought last night that might be a presenter addition for you. Can you program the wiimote power button to display and control what looks like a laser dot on the screen? I figure this would fill out that last item of the ubiquitous laser pointer in a presentation remote device. Perhaps it could be a momentary function or maybe a 'laser dot' function that could be assigned to any button. Just a thought. Also, is it possible to program a double or triple command into a button like "Shift +" ?

Jason:

Your programming and use of the wiimote is just what I've hoped would come into being. I've wanted to make use of it as an uber device for the presentation of architectural graphics on charrettes (intense week-long design sessions with clients to develop design concepts interactively). We use SketchUp, Revit, Google Earth and Powerpoint almost always and your clever research can now make that work so much more dynamic. Thanks a million for pulling it all together.

After seeing your video I had an idea that might help you with your IR source. I just saw these online today and think it could be a beautiful solution, LED throwies. (see link below) A neodynium magnet, a button battery and an LED and you're in business. I just happen to have a number of these lying around because of recent Wii pen constructions. It took all of a couple of minutes to put it together and that was mostly to go to different rooms to find the pieces. See result below. Even this tiny neodynium magnet can 'find' a metal fastener in a gypsum and wood stud wall. It work even better in a comercial building with metal stud walls. I hope this helps. You certainly have helped me with your wiimote presenter program!

IR Pens / Side-Mount LED test
« on: May 17, 2008, 05:09:07 AM »
Prompted by benpaddlejones' "Summary of IR Pens & Interactive Whiteboards that work" I did some wiimote testing at work. I used blank slides in powerpoint and wrote on the screen with different distances and mounts for the wiimote. I found the side-mount pen to be most effective even out to 15 feet. The wiimote really starts to lose resolution after that. The wiimote did pick up the single side-mounted Vishay TSMF3710-GS08 IR surface mounted (SMT type) LED at 15 feet, but you could tell that it worked better with two side by side LEDs to make a bigger IR blob for the wiimote to track. (thankyou gabort for pointing this out in your post 'big motha') I've posted the powerpoint slides below for your review. The fun thing was that people kept stopping by to play with the wiimote whiteboard so some of their diddles are included.

Here is a link to the side-mounted pen approach:
