Chinese search giant Baidu has formally launched its answer to Google Glass, but unlike Mountain View's creation, it doesn't actually come with a display. The headset, called Baidu Eye, wraps behind your head instead. It recognizes voice and gesture commands, including being able to look up anything you want like plants, bags or clothes just by encircling any object in the Eye's line of sight with your finger. The system then sends the results to your smartphone in the absence of a display. That's not the only thing the company showcased at its recent annual developers' conference in Beijing, though: it has also debuted its new smart chopsticks, which originally began as an April Fools' joke.
