The Internet of Things Becomes the Location of Things [CES 2016]
These tags, featured at #CES2016, will tell you exactly where you left your keys or pets
Pixie brings a new dimension to the Internet of Things by allowing devices to find each other in a physical space. This Location of Things (LoT) platform lets you point your camera at any scene and Pixie will automatically tell you where your stuff is, even if it’s hidden behind other things.
At the heart of this technology is the Pixie Point, a small, teardrop-shaped token that sticks to your items. It sends and receives RF signals and through Bluetooth LE, it can sync to a smartphone as well as other Pixie Points.
To locate items in a room, it records the time-of-flight of emitted signals and calculates the location through triangulation. This requires at least three Pixie Points, including the one being identified.
