Spatially Aware Visualisation (InfoVis) -- "Handheld computers like Palm and many others are more and more present in our daily lives. Increasingly fitted with applications and possibilities they suffer, nevertheless, from a structural problem: their small screens offer a very limited window to cyberspace. The idea to make the PDA be aware of its position in the reference space of the user opens up a wide range of possibilities to visualisation and interaction. These types of devices are called Spatially Aware Computers. The movement of the PDA in this space allows the user to perform a series of gestures that can be used as commands for the application."
