Observing children and technology

Here at May we have an installation for children called Spin A Story which includes a large set of spinnable cubes on the wall which have different bright pictures, and a screen which can show the user on a video camera in front of the cubes telling a story with them. I keep observing that often what the children want to do is use the screen as a touch screen. There's no mouse, so they touch the screen and want things to happen! They want pictures to zoom around at their finger's command! It reminds me of theories I've read that members of this young generation are not passive observers of technology but expect to participate and make new things happen. And this starts at a very young age now. What a world these children are taking part in!
