Wiimote wiissues

2007 Jun 7, 5:29The other day I had the best idea for my Wii remote. Clearly I should use it to control the rotation of Tetris pieces in my N-dimensional Tetris game Polytope Tetris. One of the issues I described with Polytope Tetris is user input. Given a Wii remote the user could rotate a piece through 3 dimensions in a manner that's much easier to adjust to than particular keys on the keyboard.

Anyway, I did a little research into how this might work. I knew that the Wii remote used infrared for absolute positioning and Bluetooth for everything else (LEDs, speaker, accels.) I bought a Bluetooth adapter for my PC after realizing that none of my computers had one already. I used GlovePIE to ensure that my Wii remote could connect and successfully communicate with my computer. GlovePIE is actually pretty cool -- it provides a simple script layer over the Wii remote to control things like your mouse.

Since Polytope Tetris is in Java I looked for and found a Java library for operating with the Wii remote and a long forum thread discussing its use. I then read up on Bluetooth in Java. Apparently JSR 82 is the name of the standard that describes the API a Bluetooth stack should expose in Java. That is, to get Bluetooth working in Java one needs an additional package for Java that actually implements the Bluetooth Java API. This package would depend on the system so I suppose I can't fault Sun for not including it... Where to find such a package? I found a comparison list of implementations and tried the ones that support javax.bluetooth. None of them worked for me because none can address USB devices it seems or they cost money and I couldn't get the trial version working. I also tried bluesock (not listed on the previous list) which seemed promising and could produce an address for my Wii remote as a connected device but couldn't use that address.

And I thought that after I found the Wii remote Java library it would be easy... Oh well...PermalinkCommentsjava bluetooth wii technical remote jsr82 tetris polytopetetris wiimote

Worry Beads

2003 Mar 1, 5:22Today will produce the Mardi Gras parade in my town. I haven't been the previous two years, but I'm considering it this time around. San Luis Obispo, as a college town, contains many teens and young adults who enjoy occasional festivities accompanied with inebriation. San Luis Obispo, as relatively cheap beach front or at least near beach property, contains many vacationing elderly. As we all know, voting increases proportionally with age and, as such, any person under the age of thirty in public after dark is arrested. Mardi Gras is yet another of the bouts in the battle between the Youngsters and the Old-timers in the SLO ring. I will be very happy when this quarter is over. Chemistry may yet have a happy ending, but I don't know that Technical Writing can. I don't believe any grade in that class would make me think, "I'm glad I spent all those weekends working on that report". The quarter's end will also mean I can devote some time to my attention starved Polytope Tetris project. As a side note, I was tempted to, yet again, not write in the journal on account of my poor attitude tonight. However, a journal of one entry does seems a bit slim.PermalinkComments
