In the future, call a taxi, and give it to the heel.

Once an area has been poked out a notch, the gap will become bigger and bigger, even if you can't imagine it.

This is true of smart wearable devices.

Abroad have our familiar with Google glasses, Apple iwatch, and so on, while there are some "wearing fans", like the most controversial millet, its smart bracelet products are also known to us. About smart bracelet, LG and 360 are more eye on the children's body , such as the former LG on the official website released a child smart bracelet KizON, and 360 to do a child watch, but also advertised as the most accurate children's watch so far.

Smart watches are thousands of odd states, the most diverse. the intelligence of the rush to watch the river, can not but onlookers a article, on the list of Apple, Samsung, Sony and several other smart watches, we are interested in the words to see OH ~

In addition to these more popular wearable devices, there are other devices, such as a T-shirt that can play Tetris , a lighter that can help you to smoke and help you quit , and smart toy cars, There's no one to let you see the gaping.

However, the next small series to introduce this smart device, is not only can help you to rescue, but also can help you to call the artifact of the car Oh.

The new device, called "Dorothy", is an unusual wearable device developed by iStrategyLabs.

Dorothy works by installing a "ruby" on your shoes (let's call it Ruby), a small, Arduino-based Bluetooth device. Then put this little thing in your shoe, bump it with your heel 3 times, then trigger an action.

The triggering behavior can be a pseudo-call, or it can be information. Or you can set it to send custom messages and locations to your friends. If you are dealing with a dinner, especially want to leave but embarrassed to leave first, then Dorothy can come to rescue you. Of course, you may also think, now has the pseudo-call app, I also want it to do. The problem is good, but the next small series to say it's another function, pseudo-call app but no oh- emergency call car function .

The company says it can also use it to call a Uber taxi when you need to get out of a place quickly or rush to somewhere.

The Ruby now seems a little too big to be comfortable to use. But iStrategyLabs says the current model is just a prototype. The company is looking for a way to improve its manufacturing process so that it can only be as large as the current model One-third or even integrate it on the insole.

The company also said it would continue to look for other idea to apply for a patent for the technology, such as ordering pizza urgently.

As a later person in a field, or when the market is saturated, in addition to transformation, excellence may be the only way. Dorothy Current function seems novel, but not new, and its always seize the word "urgent" to do their homework, the future may not be able to highlight the siege.
