London, one of the cosmopolitan cities in the world, looks set to be the first of its kind to feature smart pedestrian crossings that is capable of detecting just how large a crowd is. This particular technology is being prepared to be introduced in the months ahead, where priority would be given to throngs of people who wait to cross some of the busiest streets in London. Just how will such a smart pedestrian crossing work? Obviously a camera will need to be in play here, where it will sense the build-up of people waiting in a virtual box, where the green light will be extended automatically until the number of people in the virtual box has thinned down.
NFC or Near Field Communication is an important technology. Its found in most mid-range and high-end Android phones, in fact Google’s mobile OS has leveraged the technology to perform crucial tasks such as mobile payments and beaming of files between multiple devices. Google’s own crop of Nexus smartphones and tablets come with NFC, though a number of users who updated their Nexus devices to Android 4.4 KitKat found that the firmware broke NFC for them. Apparently there’s a bug that renders NFC useless on these devices, but fortunately Google is aware of the bug and has also found its root cause, meaning that it will be fixed in a future firmware release.
