...investigation cited the wrong altitude for the lake bed as the key reason for the crash (neither officer aboard the second F-15E was named in the probe) but spelled out several contributing factors. The crew was tired - wearing night-vision goggles increases eyestrain and fatigue - and crashed at 2:30 a.m., the sleepiest time in the human sleep cycle. Night-vision goggles reduce depth perception, especially when there's little ambient light and the ground is flat and barren. The crew "channelized" its attention on the attack run, ignoring warning signs that danger was imminent. Finally, "expectancy" played...
...were flooded with 3-D movies, and the technology has made an occasional comeback ever since. (The highest-grossing 3-D film, oddly, was 1970's The Stewardesses, which made $27 million.) Each time, though, it's done in by the same complaints: poor image quality and headaches and eyestrain from extended viewing. Early reviews of the new models from Sony and Panasonic suggest they've solved the problem. Both use glasses that contain tiny shutters, opening and closing at 120 frames per second, in sync with the image on the screen to give the illusion of depth...
...decades, video gamers had little more to fear than “joystick elbow,” eyestrain, bad posture, or keyboard-induced carpal tunnel syndrome. Some flashy graphics sequences posed threats to epileptics, but that’s nothing new; many effects-laden television programs boast that dubious distinction...
...fluorescent bulb and a thin layer of transistors. Including their stands, flat monitors rarely extend more than 7 in. deep or weigh more than 12 lbs.; monitors with CRTs (cathode-ray tubes) are up to three times as deep and twice as heavy. Flat screens also save energy, reduce eyestrain and look really cool...
...Eyestrain's friend Hiiro, a more stereotypical geek with Coke-bottle spectacles and a microchip key-chain dangling from his belt, doesn't dabble in credit cards and says he has "knocked some sense" into his pal. (Tapping into other people's Internet accounts, however, is still considered fair game.) Both men would prefer to go legit and offer their services as security advisers to local ISPs. They're not getting far. "They just ignore us," says Hiiro. When their user databases get hacked and they find a few thousand missing credit card numbers, these websites and isps may regret...
