My sister Sue had to stop working two years ago, having been diagnosed with MSA about a year earlier and has now moved into a care-ready retirement complex near us. She's now taken delivery of an NHS-funded powered wheelchair, and I'm looking to install a Windows tablet to handle (to start with) a reversing camera and a speech synthesizer (Sue banked her voice last year, and she's becoming progressively harder to understand).
At the moment she can still handle a mouse, but I'm thinking about a pupil tracker as she's losing fine motor control in her hands.
Here's the question: Does anyone have experience with eye control? I know everyone is different, but am I right to assume that Sue's likely to retain directional control over her eyes?
And is there anything else I should be thinking about?
