How does Stephen Hawking control what is being said by his computer when he speaks?

Question

He just seems to use one finger to talk, without typing.

Also, what are his views on creation? I plan on reading "A brief history of time" but I won't have the book for a few days.

Thanks!

Answer 1

Most of S.H.'s speeches and presentations are prepared ahead of time ... for those that aren't ... :

[From WIKI]
The computer system attached to his wheelchair is operated by Hawking via an infra-red 'blink switch' clipped onto his glasses. By scrunching his right cheek up, he is able to talk, compose speeches and research papers, browse the World Wide Web, and write e-mails. The system also uses radio transmission to provide control over doors in his home and office.

Hawking receives a new computer every 18-24 months donated by Intel. One such computer was donated in April of 2005 and is based on the Centrino chipset. It consists of two pieces, a rear chassis which houses 3 160Whr batteries and various external peripherals, and a front chassis, which houses a Tablet-PC and the speakers which project his hardware-synthesized voice. The two chassis are connected via a custom-designed umbilical cable which allows power and electrical signals to travel back and forth. Hawking's computer can run for up to 16 hours without needing a recharge.

The computer utilizes a wireless data card that runs on mobile phone networks. This allows Hawking to check his email and browse the web while away from a wireless LAN. Hawking can also make and receive voice phone calls via a mobile phone with an external microphone in front of his computer speakers.
