There is a muscle in his eye that he can twitch which is connected to a screen. he twitches when it flicks over a the alphabet, letter by letter, and twitches when it is on the letter of the work he wants. he then does the next letter, twitching when it is on the word he wants he can do this at a rate of 4 words per minute by twitching a muscle in his eye

What is the difference between radio and remote controlled?
There are a few differences. Radio controls use radio waves and reach a longer distance. Remote controls usually use infrared or bluetooth and are usually for only short distances.Remote control means (roughly speaking) remotely controlling a device using something that is not part of the device itself. The controlling device can be attached to the device using a wire or wires to transmit controlling signals. It can also be unattached with control signals being transmitted using radio signals, or light waves (infrared, ultraviolet). A more sophisticated device can also use standard network communication protocols along wires or WIFI or Bluetooth for communication and control.Radio control is remote control using radio transmission.
What inventions were influenced by the radio?
The radio is believed to have been invented by Guglielmo Marconi but recent debates have proved that it was Nikola Tesla who first demonstrated the device. Some inventions that were influenced by the radio were the remote control, television and satellites.
Is remote control the same as radio control?
Not usually, remote control may be via wires, hydraulic, radio waves or smoke signals, Radio control refers specificaly to items controlled by radio.
Was the radio the first mobile device in the world?
no, first mobile device was a knife...
Who sings the songs on Stephen a smith radio show?
Smith
What is a remote control used for?
A remote control is used to control an electronic device form a distance without wires. It uses infrared or radio frequencies to transmit the data to the device.
What is a RC transmitter used for?
According to information RC transmitters relates to radio signals for a remote control device. The radio singles are transmitted to any device that has been designed to work by remote control such as toy helicopters and remote control cars to name just a couple of remote control types of items.

What is an RF remote?
An RF remote is a remote control device that uses radio frequency (RF) signals to communicate with and control electronic devices. RF remotes do not require a direct line of sight to the device being controlled, unlike infrared (IR) remotes which do. They are commonly used in situations where the controlled device is not in the line of sight of the user.
Where do you listen to radio?
in a car or radio or radio playing device :)

Can you control radio waves controlled equipment with the help of an infrared source?
If I understand the question correctly, you're basically asking if you can use an infrared remote instead of a radio remote to control a radio controlled device.Let me say that again: radio controlled device.No, you cannot. If you're an electronics engineer, you could probably substitute some kind of IR receiver for the radio circuitry, and then you'd be able to control it with your infrared remote. But at that point, it would no longer be a radio controlled device.
Was Stephen hawking paralyzed?
He is not paralyzed, he suffers from ALS (or, in American colloquialisms: Lou Gerig's Disease). 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.

What is a radio control servo?
A servo, or servomechanism, is an automatic device that uses error-sensing negative feedback to correct performance. http://en.wikipedia.org/wiki/Servomechanism
