Navigability, part 2:
Reading & Editing
- An expert handler will know to handle specialized content
in both a read-only and an editing scenario using three conditions:
- 1. level of granularity,
- 2. mode of input/output, and
- 3. which item (first, last, previous, current, next);
- Read-only:
- 1. the AT responds a Point of Regard change event, using the role of the object which received focus
- 2. the AT fetches accessibility information pertinent to that role and then formats/outputs a response tailored to an AT user
- Editable content:
- separate cursors are needed:
- a) one to remain at the POR (the caret, if editing), and
- b) one to move around for review purposes
