We've certainly seen displays that look right back at you for interactive purposes
, but a new system developed by Wayne Cheng and Chih-Nan Wu at the Photonics and Display Institute, National Chiao Tung University in Taiwan could enable the LCD
to alter itself based on your viewing location. The researchers have devised a solution in which a camera tracks the eyes of the onlooker and subsequently uses software to adjust the "orientation of liquid crystals in the display and the power fed to light-emitting diodes behind each." The result is an image that remains clear and sharp regardless of how you're looking at the screen, and while the developers admit that it can only respond to one set of eyes at a time, they're hoping that "doctors and surgeons
who use LCDs to view scans or X-rays" would be among the first to benefit.
