Would You Wear Video Glasses?
Roland Piquepaille writes "According to EE Times, an Israeli company has developed a personal video display device that looks like a simple pair of glasses. You can use these glasses with various sources, such as a portable media player or your cell phone. This technology promises to eliminate the dizziness phenomenon usually associated with this kind of display. And with these glasses weighing only about 40 grams, you'll feel that you're viewing a 40-inch screen from a distance of 7 feet." Video screens embedded into eyewear isn't that new, but the footprint of these is smaller than what I've seen before, making them cooler to wear on the subway.

Just an inverse relationship. So many ways to explain it... so little time.

Well the '7 feet' is the distance at which your eye has to focus. It is a constant which depends on the optical properties of the glasses. So no, you cannot say that it is the same as being 1 inch away or a movie theater away. Those don't feel the same even if you match the angular size of the image.
No, the crabs are still a problem.
You may want to double-check your numbers. The area may diminish as the sqare of the distance, but we aren't talking about a forty square inch screen. We are talking about a linear measurement, which is a proportionate difference. Twice the distance appears to be half the size. So forty inches at seven feet is the same as 5.7 inches at one foot, or just under one inch (.952 inches) at two inches distant.
