Pronunciation: Hawking uses an equalizer pronunciation program developed by Words-Plus, which sounds a bit like an electronic dictionary with an American accent (some people say it looks like a Nordic accent). When he visited Hong Kong in 2006, he said, "The original system still had English with a French accent, but if I use this accent, I'm afraid my wife will divorce him. 」
Telephone: there is a wireless telephone system, which can dial or receive lines directly through the computer.
Universal remote control: The wheelchair is equipped with universal infrared remote control, which can control TV, video recorder, listen to music, lock the door and turn on the light.
Storage: Hawking is used to storing all his speeches and papers on a storage disk, and theoretically any speech can also be stored.
Power supply: the battery is hidden under the wheelchair, which can support both wheelchair and computer operation.
Typing: Hawking's glasses are equipped with infrared emission and detector at the upper right. As long as he moves his eyes, infrared detection can select basic letters from the screen and then select words in the lower part of the screen. When entering complex formulas, he will use TeX (a formula compiling software commonly used in the scientific community and supported by Wikipedia). For example, he will enter $ {-b \ pm \ sqrt {b 2-4ac}? \ End? {2a}}$, the solution formula of quadratic equation can be obtained.
