...Pavilion at Energy Expo '82 (a.k.a. the Knoxville, Tenn., World's Fair) as exuberant children and their more inhibited parents discover that TV viewing is passive no longer. The technology is called the interactive videodisc: the symbiosis of the computer and the laser-vision disc...
...touch-sensitive screen. Pressure on the screen tells the computer to retrieve the information stored on the videodisc corresponding to the word or symbol touched. Although the computer makes the system truly responsive, what makes its applications so exciting is the versatility of the videodisc. And you thought the disc was the Edsel of video technology...
...Selecta Vision, 15 years and $200 million in the making. Not a truly innovative technology, Selecta Vision is essentially a phonograph that uses a mechanical stylus to play prerecorded movies. Its costly debut obscured the second type of videodisc: the infinitely more versatile laser-vision disc, designed for the videodisc player introduced by Magnavox in 1978. Manufactured by Pioneer, Sony and the 3M Co., the laser-vision disc makes flexible interaction possible...
More sophisticated and more expensive than the stylus disc, the laser-vision disc not only offers enormous storage capacity but provides random access and perpetual durability. A low-powered laser beam "reads" billions of microscopic pits of information imprinted on the smooth, shimmering disc. On each side are stored 54,000 images, any one of which can be called up instantly on command. The stylus and laser systems are incompatible, which leads to a great deal of consumer confusion. Moreover, unlike the video cassette recorder, the systems cannot record from television. Currently there are three videodisc machines on the market...
...cardiopulmonary resuscitation disc, developed by the American Heart Association to instruct trainees in saving cardiac arrest victims, is so interactive that it practically cries "Ouch!" The disc is linked to a mannequin equipped with 14 sensors, and it tells the trainee exactly where to push, pound, pinch or pummel. Instructing the trainee how to compress the victim's chest, the videodisc might say, "Find the notch on the sternum," or perhaps, "A little more gently this time." At the course's conclusion, the system gives a complete exam, grades it, and can certify the student in cardiopulmonary resuscitation...
