A robot, remote controlled by motion capture, moves in perfect sync with a person in the distance. A device passes an infrared scan over some food and supplies complete nutritional information about the fare. These are among the array of cutting-edge technologies on display as Japan¡¯s largest electronics trade show kicked off Tuesday.

This year¡¯s annual Combined Exhibition of Advanced Technologies (CEATEC), which will run through Friday at Makuhari Messe in the city of Chiba, is seen as a touchstone for the 17-year-old trade fair.

Undergoing a major revamp last year, what had been a showcase for consumer electronics such as TVs and washing machines had reinvented itself as a business-to-business exhibition across sectors oriented toward the internet of things concept, in which everyday items are linked by network.
