An American scientist is to unveil details of work on the brain patterns of Prof Stephen Hawking which he says could help safeguard the physicist's ability to communicate.
Prof Philip Low said he eventually hoped to allow Prof Hawking to "write" words with his brain as an alternative to his current speech system which interprets cheek muscle movements.
Prof Low said the innovation would avert the risk of locked-in syndrome.
Intel is working on an alternative.
The iBrain is a headset that records brain waves through EEG (electroencephalograph) readings - electrical activity recorded from the user's scalp.
The i-brain
Prof Low said he had designed computer software which could analyse the data and detect high frequency signals that had previously been thought lost because of the skull
