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

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.
