A woman is crowdfunding and selling her belongings to pay for equipment to help her disabled husband communicate.
Nigel Bassett is unable to move or speak following a near fatal road crash in Cornwall three years ago that left him with a traumatic brain injury.
His wife Wendy Bassett said he was able to communicate with her by blinking, but it was not widely considered to be a reliable form of expression.
Unlike eye-gaze technology, she said, that could give him some independence.
The computer works by tracking Mr Bassett's eye movements, which enables him to select phrases, words and programs from a screen.
Gaining access to the technology would also mean Mr Bassett could communicate directly with doctors and specialists rather than via a third party as he currently does.
"Because Nigel uses his eyes for blinking, in a court of law or in the medical profession it's not considered a reliable means of communication, because we all blink all the time," Mrs Bassett said.
"When I ask Nigel to blink, and I'm not happy that it's a clear blink, I ask him to slow down and he does and he understands what I'm asking and he'll blink more clearly but it's still not accepted as a reliable means of communication."
'Life more important'
Mrs Bassett has set up a crowdfunding campaign to help buy the specialist technology from a Swedish company.
The computer costs almost £10,000 so she is also selling the couple's non-essential belongings to help fund the purchase.
So far the campaign has raised almost a third of its target.
"Neither of us are materialistic...we don't put value in things," she said.
"You think about what's important in this life, is a TV really important? His life is more important than things."
