How about Sunglasses that Will Text You When You Leave Them Behind


With iOS 7Apple introduced iBeacon, a protocol that uses Bluetooth low energy (BLE) to determine your location down to within a couple of feet. We’ve already seen some innovative uses of iBeacon — for example, Major League Baseball uses it within its stadiums, while Apple uses iBeacon in its retail stores to alert customers about discounts on nearby items.

But iBeacon is just getting started, and Gizmodo alerts us to one of the more interesting implementations of iBeacon from a company called Tzukuri. Tzukuri put a tiny (3 millimeter) iBeacon chip in its sunglasses to alert you when you’ve accidentally left them behind. When your sunglasses are more than 16 feet away from your phone, you’ll get an alert, and then again at 32 feet and 50 feet. If you venture farther than that, the Tzukuri app will keep track of the last location it had for your sunglasses.

The iBeacon chip is incredibly small and is not noticeable in the pictures on Tzukuri’s website. Tzukuri also added a small solar cell, so it should never run out of battery. If it does, Tzukuri says, you need only to stick the sunglasses in the sun for an hour to recharge. The alerts work both ways, too, as your phone will start ringing loudly if you are wearing the sunglasses and leave without it.

The sunglasses are going to cost a bit more than a cheap pair from the supermarket, however, and will be priced at $349 when they ship this coming holiday season. However, there’s a reason for this. Each pair is handcrafted and will come in one of six designs, each based off the style of glasses worn by six iconic figures: fictional lawyer Atticus Finch, President John F. Kennedy, designer Tom Ford, Beatles legend John Lennon, actress Grace Kelly, and writer Truman Capote.

The sunglasses are available only for iPhones, and Tzukuri doesn’t look like it will be supporting Android anytime soon, as its FAQ says it will not support Android until “BLE becomes more standardized across Android handsets.”
