Redmayne shared, “Absolutely extraordinary. It is the best possible use of technology that professor Hawking uses. These people (pointing to Intel scientists) are among the most interesting I’ve ever met.”
Intel managed to develop this particular technology with some input from Hawking, as both parties have had a longstanding relationship. How does this new Intel user interface work? Just like an engine, really, where there is a sensor that has to be mounted on Hawking’s cheek which can be detected by an infrared switch that is attached to his glasses. This would then assist Hawking to select a character on his computer, where all the relevant information will then be sent over to his speech synthesizer.
