However you choose to store your pictures 鈥� on film or microchip 鈥� you may still lose that picture of a lifetime while fumbling for the 鈥渟hoot鈥� button. The answer is to make a camera that takes a picture when you blink, says Hewlett-Packard (GB 2 380 551). A low-power LED in a viewfinder shines on the user鈥檚 eyeball while a photosensor registers the reflection. Blinking changes the reflected pattern. The camera interprets a short blink followed by a long one as a 鈥渟hoot鈥� command. An optional setting lets it take pictures automatically if it senses a rapid series of blinks. Just don鈥檛 sneeze.
