Mary Jo Foley's take from CES:
The only truly futuristic technology that Gates showed during his hour-plus CES appearance was a piece of visual-recognition software under development by Microsoft Research that, some day, may be integrated into cell phones and other devices. Gates pointed a black-box mock-up device at faces and the software instantly recognized and identified them, providing all kinds of related information (like how much money they owe you). Point the device at a theater and it provided the theater name, address and a list of movies playing. Gates showed a slick, 3D interactive interface that would act as the central focal point for all of the visual data stored on a device, organizing it into browseable categories.
