Selection Technique Notes:

Direct

This term is meant to capture the essence of being able to select the exact key/item/leaf directly.

Scanning

This term is meant to capture the essence of not being able to select the exact key/item/leaf directly, and is associated with a notion of "indirection", and "time assisted" selection.  Also note that users can habituate with scanning, and that inverse scanning allows untimed advancement of selected group or item.  It is conceivable that a user could habituate a sequence of signals with an key/item/leaf selection when using inverse. Which leads us to...

Visually Cued Coded Access

The "Coded Access" part describes the ability to map, a sequence of signals to an exact key/item/leaf directly.  The "Visually Cued" part injects a notion of indirection.  The level of the user's habituation places a role in the "direct-ness" of this technique, and the dynamic keyboards will contribute to the "indirection-ness" (since they might not allow habituation.)
E.g. Visually Cued Binary Access ("Morse") .

Grouping Notes:

Row - Item (aka Row Column)
Column - Item (aka Column Row)

Known Clinical Access Method Instances


Miscellaneous

There is no such thing as a Selection Method.  Or maybe it is just the abstract marriage of the Selection Technique, the Grouping, and the Controlling Actions, but not an instance.  An Access method is an instance.
