Physical interaction design DH2400

Here is a video I showed to the "make_music_with_random_objetcs_of_the_everyday_life" group. Very simple (except it needs to be plugged to real electricity) but still fun.

I played around yesterday night with sunspots for the first time.

Some experiences:

* Sunspot manager is a good tool for making things simpler, eg upgrade the physical sunspots, tutorials, docs etc
* Netbeans plugins makes the work simple cause it gives use the option "build and deploy on sunspot"
* Dont forget to setup some permissions in the shell (if you're using mac):

sudo mkdir /var/lock
sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
sudo niutil -appendprop / /groups/uucp users

I missed this step and my Sunspot Apps only gave me weird error messages. The last row seem to be different in OSX 10.5

A funny idea from this Australian, Kyle Downes. No phidgets inside, but 4 big buttons and a D-pad that made me think about our projects. Here are some pictures about the wood structure and the 'A' & 'B' buttons, and a video of the final result.

Take a look at http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2008/12/10/BAF214L2I2.DTL to see what students at Berkeley are doing in a similar course as ours.

There seems to be a LivingSurface application in Täby Centrum!

My kids played with this for almost two hours yesterday. It seems to be quite a simple installation, based on an overhead video projector sending pictures to a white mat (on which kids run) and a video camera, most probably running a multi-touch table software, to detect the various moving spots (aka kids). It reacts more to kids who have darker clothes. There are some soft toys at one side, unrelated to the projection but giving a nice "play" and "kids" context.

There are several scenes (balloons, flowers, water) and some of them are better designed, in that kids realize faster that the they are interactive. In one scene there are some butterflies that run away from the kids, but these are somewhat too small to notice. The water scene makes waves when kids "kick" the water, which are nice and probably challenging to do from a computer graphics standpoint, but not easy to notice when you're running around (still fun to play with once noticed). The balloons and flowers work best, as kids see them rushing away as they run around.



This looks like a commercial installation, quite reliable. It became a bit less reactive as the closing hour was approaching, not sure whether that was on purpose or it became de-calibrated. A great installation all in all, kids clearly enjoyed it.

I just want to give everyone a tip about the course site for Microcomputers in products; www.md.kth.se/mip. Here you can find lots of useful links, crash courses and info about detectors, motors, robots and so on. Enjoy!
