Communicationg strategies
Low‑Tech AAC
-Early on during acute and subacute rehab
If look to all directions→ transparent board
If only up/down→ technique (go by line, and then letter)
>Eye‑blink systems (1 blink = yes, 2 = no)
>Eye-gaze boards (alphabet boards, color-coded grids)
>Partner-assisted scanning
>Simple speech-generating switches, if any movement available (e.g., toe, finger, head, eyelid)
High‑Tech AAC
-Stable eye movement or small residual motor control
>Eye-tracking communication devices (e.g., Tobii Dynavox, EyeLink)
>Brain–Computer Interface (BCI) systems (experimental but promising)
>Speech-generating AAC tablets
