I run into an Apptivity toys commercial online. I think it’s a pretty cool idea. Apptivity toys are physical toys that you can use on the surface of the iPad. For one thing, it extends the limits of hand gestures and finger sizes. For another, it extends the limits of the touch surface into the psychical world. It’s a combination of touch user interface and tangible user interface. So children who grow up with tablet touch surfaces will also have the direct opportunities to play the physical toys with the virtual world. I can see that it will be even cooler to play these toys on a larger touch screen than the iPad. I understand that they made the toys suitable for the iPad because it would be easier to be adopted since so many people already have the iPad. This is one step further to integrate the physical world and the virtual world.
