Its designer Tour Ichihash.

P-ISM was first featured at the 2003 ITUTelecom world held in Geneva, Switzerland.

Look closely and guess what they could be...

P-ISM (“Pen-style Personal Networking Gadget Package”).

Connected With A Wireless Technology.

Whole Set Is Connected To Internet Through Cellular Phone Function.

This 'pen sort of instrument' produces both the monitor as well as the keyboard on any flat

 surfaces from where you can carry out

functions you would normally do

on your desktop

computer.

ConclusionThis 'pen sort of instrument' produces both

the monitor as well as the keyboard on any flat surfaces from where you can carry out functions you would normally do on your desktop computer.

The communication devices are becoming smaller and compact. This is only an example for the start of this new technology. We can expect more such developments in the future.
