As part of the design phase I produced a map of the modes of interaction in the various application components – this again is inspired by the approach to design used by Bill Verplank.

This map takes four modes into account:

1. Feel: split into seeing and hearing
2. Do: split into mouse and keyboard

See it here (click for full version):

One thing this does is develop a feel for the different modes of access.

Actually implementing these modes is very difficult in today’s applications as things like keyboard and text-to-speech are platform-specific. So seeing the full keyboard and speech experience will have to wait until M2 at the earliest.
