I've been careful to make it in my live presentations but probably don't mention it enough here on the blog. The reset button in the battery compartment is very useful for making a connection. When I'm doing wiimote stuff I have the battery cover off all the time and am hitting that button constantly. Dan,

This did not work for me, my controllers have a red "sync" button located in the battery compartment of the wiimote. I spent and hour holding down the two buttons wondering why it would not work, so I hope this information helps saves someone some time. I collected a few tutorials here if it helps? http://ubuntudan.blogspot.com/search/label/Play%20Wii%20on%20Ubuntu Most of the connection tutorials I have read told me to press both the (1) and (2) buttons down while connecting to bluetooh.

I get the enjapen application running and the described hack works fine, that means it returns the IR values. But I'm not that deep in PyObjc...could someone please show, how to actually connect to the mote and access the data in small script? I guess this could be done in 10 lines, but I don't get it! Thanks in advance, christian Hello!

I'd be slightly skeptical of that... Another option is to position more than one wiimote in your environment and aggregate the data with triangulation techniques. Then again its sort of like hitting a screw with a hammer...augmented reality and marker recognition seems much better suited for light sabre control... Re: Jason Shouldn't the Darwiin Remote be able to detect a failed sync and retry? Re: john

I'm excited to see DarwiinRemote be used for this sort of research. Really good stuff. The connecting bug is annoying. We (the DarwiinRemote team) consulted with Apple via their Bluetooth dev list. It is a byproduct of Apple's Bluetooth drivers. It's just the way it is. *Sigh* Someone mentioned that they got around it by never stopping the discovery process. Just let the framework constantly be discovering; it might help. Thanks for the detailed write up. I’m excited to see DarwiinRemote be used for this sort of research. Really good stuff.

It is to open up the battery compartment and connect by pressing the red sync button. Of course this is a pretty poor way of connecting, but it seems to work every time. I'll have to check out the htdp. Writing the data out to a socket is certainly another way around the problem that I faced getting the IR data. For my projects i think that I am always going to want the raw IR data. One of the things I'm planning on doing next is making a light saber sensor bar out of pvc and ping pong balls that would allow me to do both head tracking and a light saber at the same time. I would need the raw IR points to do that. Also, you could use multiple IR sources to do better head tracking with the wiiMote. Two points suffers from the problems you mention. But you could do three or four points and resolve those problems pretty easily. For instance, with four points (a box around the face) you could distinguish between someone turning their head and someone coming in closer. Christian,
