The second week of physical computing. Experimenting with difirent sensors. Reading data from them. And looking into some Alt Ctrl games.


  1. Find an interesting existing Alt+Ctrl Interface

There is little information on the website about what exactly the game is. If we imagine that it is related to the simple game where you draw on someone’s back and they have to guess what you are drawing, then the force sensor shows what is being drawn.

It can also show how the drawing changes over time if the force sensor is worn by several participants.

While trying to find an interesting game, I also found this website It was initiated by the author of the game “Guily Smells”. Pili and Janne have written a bit more about the game if you want to know more.

Wine tasting game where you have to convince the waiter that you are a wine expert. You have a glass in front of you and you have to swirl it in a certain rhythm. If you swirl it too much, the waiter will get impatient. If you swirl it too little, you will lose respect points. To detect the swirling motion of the wine glass, there is an accelerometer under the glass. The accelerometer can detect the speed and count the number of swirls you make with the glass.
