Le Digit - Penne che comunicano .

The design concept uses five different pens to make a computer. One pen is a CPU, another a camera, one creates a virtual keyboard, another projects the visual output and thus the display and another a communicator (a phone). All five pens can rest in a holding block which recharges the batteries and holds the mass storage. Each pen communicates wireless, possibly Bluetooth.

The design paradigm in P-ISM is quite different than a notebook, PDA or even a cell phone. Each of these are self-defining by their shape and form factor which is one integrated unit. This is good and bad. It is good in that if the unit can be positioned or held the way it is defined it works well. The bad aspect is that all like units are just that – alike. While what the P-ISM seeks to do is to create a new form factor based on the individual user. However, this has its own compromises – a surface is needed to make it functional. What is important about P-ISM is that it challenges the notion of what is a personal computing device in a form factor which begins as a pen but is much more.
