Here boy. Good dog! The Hop suitcase will follow you at a respectful distance - until you take the stairs.
Named after a bellhop service, this tracked luggage will follow you wherever you go - automatically, all controlled by your iPhone.
The suitcase is stocked with three receivers that triangulate the user's phone's position over Bluetooth. A microcontroller does the calculations and keeps it at a close distance.
The suitcase is security-minded too. If it gets lost, the user's phone will vibrate and Hop will lock itself up tight.
While the case is still in prototype, it has attracted a lot of interest from travelers tired of lugging their luggage. And lottery winners too, maybe.
