Check out this cool concept pen from designer Reuben Png.
The D:Scribe is a digital fountain pen that allows users to send SMS and email messages from paper. Just write out the message and circle the persons name to send. This does away with a keypad and allows you to focus on communicating in a more personal way from anywhere as long as you have a bluetooth enabled phone and a surface to write on. The pen also records everything you write which can be accessed on a computer. Of course for the creative peeps, if writing doesnt suit your fancy, the D:Scribe also works with genius and not so genius drawings of brilliance.
Once a message is sent, the status is displayed on the built-in OLED screen. The designers have also expanded its capabilities beyond that of messaging. Should your home electronics and appliances be bluetooth enabled, you could potentially program the pen to input commands by writing in the air. A little abstract but lets pretend this idea is more a patent for possibilities.
