Choosing an access method

Public AAC’s boards are operable four ways — the board itself never changes, so a person can move between methods (or mix them) without relearning anything. Choose in Setup → Access:

Method	How it selects
Touch	Tap a cell to select it.
Switch scanning	The highlight steps through cells; press your switch to select.
Dwell	Rest the pointer on a cell to select it.
Head / gaze	Move your head to point (using the camera); rest on a cell to select.

The app annotates — but never disables — methods the detected hardware can’t currently drive: an external mouse, switch interface, or eye tracker may be attached at any time, and that judgment belongs to the person, not the software.

Setup → Access: pick how the board is operated.

Each method has its own settings page: Touch · Switch scanning · Dwell · Head and eye gaze
