Communication with other devices

o Earlier communication is through radio transmitter

o Currently it is done via a cable and an ‘inkwell’

o Future models provide wireless facility

Memory

• 4MB EEPROM

• Capacity- 10 pages

Power

• AAA Battery

(44.5mm long,10.5mm in diameter & 11.5gm in weight)

• Run for 25 hrs on single battery

• Automatic power on/off system

Application

• Used as ordinary pen(ink catridge)• Replace keyboard with Smart Quill• Handheld comp

application(alarm,clock,contacts)• the wireless messaging system which

allows two way communications • voice record and supports speech

recognition.

Advantageso "Spatial Sensing" system o Intuitive user interface o Security

Handwriting recognition

Signature verification o Power saving o Smart Quill is all mobile

Conclusion

The future of Smart Quill ensures all computation power the user needs right inside the pen.

Reducing the size of handheld computers can only be taken so far before they become unusable.

The introduction of Smart Quill is the best

solution for this problem.
