Communication with other devices

• Earlier communication is through radio
  transmitter
• Currently it is done via a cable and an inkwell
• Future models provide wireless facility

16
Memory

• 4MB EEPROM
• Capacity- 10 pages

17
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

18
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.

19
Advantages

• "Spatial Sensing" system
• Intuitive user interface
• Security
• Handwriting recognition
• Signature verification
• Power saving
• Smart Quill is all mobile

20
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.
