I'm currently working on an interactive information design project called squeeze and learn. The interface is a plush soft toy, with a built in screen, most probably pocket pc on its belly. A child is supposed to squeeze the toys hands to trigger a flash presentation on the pocket pc. My problem is how to make myself a sensor that can somehow trigger the pocket pc.
Here's my idea so far : To use a camera release cable to 'keypress' a keyboard connected to the pocket pc. The keyboard does not necessarily have to be built in, just hidden somewhere.
Now my question: What should I use for the squeezing part, and somehow press down the camera release that will then press the keyboard? Or does anyone have a better idea to do this whole thing?
