Volvelles multi-touch hardware is now working

May 19, 2008

What you see in the video is the hardware for the Digital Volvelles project. The app that is being used is just a Flash application that is bundled with the touchlib project: 


Creating the print material

May 17, 2008

While Niqui, Johannes, and Lelo are fully occupied to make the wheels working digitally, I’m kind of working on both sides – digital and print – to prepare everything for the show set up in June. The supporting print material is going to present useful and additional information how everything works. For example, two posters will show all possible combinations that can be arranged with the digital wheels in order to get a different kind of information. The work itself is getting quite complex, but somehow everything comes together now.

Steps to create the posters based on the digital interface, which are going to show all possible combinations:

Design Elements & Storyboards

May 9, 2008

I’ve finished the working paper that is going to be an essential manufacturing paper as it consists of all the facts, figures, and measurements concerning y/x axis values, colour values, type values, etc. It also explains the status and movements of the wheels and their outputs with detailed storyboards and further describtions.

It starts with a visual about sizes, types, and transparencies:

This is followed by another visual overview about the main 3 elements of the interface: sidewheels, centerwheels, and overlayers.

The paper includes detailed storyboards about movements, hierarchies, drags&drops, overlayers behaviours, etc. Here are a few examples:

1. Wheel hierarchy – order and re-order:

2. Turning wheels

3. Interaction between wheels, and wheels with overlayers

All visuals are created with Illustrator, which allows a really good work procedure with Flash.

How to connect a Wii Remote to a Mac in Bootcamp

April 24, 2008

I tested the procedure to connect a Wii Remote (Wiimote) via Bluetooth with both a Mac Mini as well as a MacBook in Bootcamp with Windows XP. However, I cannot guarantee that it works with all Macs in Bootcamp. Definitely a problem is, that I’ve got only a German XP for testing purposes. Thus I can’t guarantee that I found the right translations for the names of buttons and labels in the XP Bluetooth wizard.

  1. In “Systems Preferences” go to “Bluetooth devices”
  2. If there already is a Wiimote listed, press “Remove” (yes, it’s tedious but I could not figure out another way.)
  3. Click “Add Device”
  4. Select “Device is ready to be found”
  5. On your Wiimote click both 1 & 2
  6. Immediately click “Search devices” in Bluetooth devices window.
  7. After Bluetooth devices have been found select “Nintendo RVL…” and click Next.
  8. Choose “No key necessary” and click “next”. Attention: Wiimote must still be blinking after this step. If you’ve done everything right a bubble should appear over Windows’ task bar which tells you “New HID device found”.
  9. Start Wii yourself’s demo.exe. A Dos shell window opens up with the message “Searching for Wiimote”
  10. Press 1 & 2 buttons of Wiimote if not blinking. Attention: demo.exe should now tell you “Connected!” behind “Searching for Wiimote”.
  11. Close demo.exe.
  12. Open up the application in which you want to use your Wiimote e.g. Johnny Chung Lee’s Wii Whiteboard. Attention: I was not able to use the exe that was provided on the download page of the project’s Sourceforge page. I had to open up the project in Visual Studio (I used the VS Express 2008 version that is freely available on Microsoft’s homepage) and press the play button in the menu bar (next to “debug”). Then everything worked just fine.
Update: Just figured out that I’ve forgot to upload Demo.exe. This is a Dos application, which shows the basic functionalities of the WiiLib project when a Wii remote is connected to the computer. Anyway you can download the source yourself from their page and compile it with Visual Studio (a VS project file is included) but somehow the compiled Demo.exe failed to work on some computers. So if you just take my version of Demo.exe you will be faster and the possibilty that you will be successful is higher. Demo.exe
I hope your virus scanner will try to kill if you’re about to open a downloaded, zipped exe from the Internet 😉
