ZigBee devices displayed by the company in San Francisco included a key hanger that helps keep track of keys.
The hanger wirelessly connects to a user’s mobile phone and, when the two get out of range, the mobile phone will warn its owner that they have lost their keys.
The phone will be able to tell if it is at home, the office or some outside location by looking at what other devices are within range.
“That way we make sure that the owner won’t get a warning when he is at home and the system loses track of the keys, but that he will get warned when he leaves a restaurant without them,” explained Kenneth Cornett, scientist with Motorola Labs.
Similar solutions can be built into sunglasses and other easy-to-lose items.
