Have you ever lost your glasses in the past? It’s not fun to experience. You are going to have a harder time losing a pair of Tzukuris. These have beacons embedded in them, which means you can track their location on your phone. If you leave your Tzukuris behind, the companion app sends you an alert at 16 feet. You will receive further alerts until you clear your notifications.
The app tracks your distance to the nearest foot and also saves the last location you had your glasses on a map. It uses Bluetooth LE to connect to your phone. It has a solar-powered cell, which is a plus. The developers are using iBeacon technology to build these glasses. Just bring your iPhone 4s or later, and you are set. You don’t even need the app running in the background for Tzukuri to function.
Tzukuris will be available in 6 designs and 3 sizes. They are handmade in Japan. These glasses could prove useful for folks who are just tired of losing a pair every few months.[Source]
