The screen of your watch too small? Use your skin!
Source:
After Apple introduced its smart watch, there was a real boom of these devices. If you compare how many people now on the street with smart clock, and, for example, 5 years ago, the difference is tenfold. However, there are such gadgets, one problem: if information they display is still normal, but with the input of some data is constantly experiencing discomfort. The problem is the small screen, which rarely exceeds the diagonal one and a half inches. But put on your wrist the 5-inch display, like a smartphone? Of course not. And German scientists have offered their solution to this problem, and you don't have to buy a new smart watch.
Scientists were able to make the most common smart watches can recognize touch magnetic stylus the wrist of the person. For example, you want to send a text from your watch or a small figure, pick up the stylus and... draw directly on your skin. Stylus completely improvised — there is a magnet and the sensor touch on the end, which determines the contact with human skin. You better take a look — the holder does not allow you to embed videos on other sites except YouTube.

As an ordinary watch could work with a stylus, like in a spy movie? It is actually just — they used a magnetometer that is built into any modern phone from which you are reading , or smart watch.
Why the magnetometer in hours, do they measure the Earth's magnetic field? Actually, Yes — this device allows the device to determine directions for improved navigation. Due to the magnetometer operates the built-in app compass in the iPhone and other smartphones, a smart watch and understand where you are and where you need to rotate below not to stray from the route.
In the case of scientific experiment, the magnetometer, in hours, after calibration, was able to determine the position of the magnet on the stylus tip relative to hours. Developers only have to write for hours graphics editor with extended functionality, which can be controlled with a stylus.
In the study, researchers tested the input with a stylus, as well as on the watch itself. The stylus is much faster and more accurate. However, much depends on the skin. If it is rough or there is too much hair, the accuracy of the stylus becomes less. In addition, the continue to drive the stylus of the clock, the worse occur triggering. The magnetometer in hours not so much "long-range" to detect the touch, for example, on the palm.
Why? Now smart watch become a full-fledged device, not just a "companion" for your smartphone. With them go camping for a run, leaving the phone at home. A clock is able to receive calls and operate independently. However, to interact with 1-1,5 inch screen — the torture. Here you can take a stylus (embedded small in the case of the watch or strap, for example) and to obtain possession of additional space for interaction with the clock. Although it would be even cooler to somehow attach a magnet on the tip of your finger and paint or, for example, to scale map not on the clock, and next to them, a characteristic gestures multi-touch.
Before that, I remember, complete with almost every touchscreen mobile phone was the stylus — an electronic pen for entering text or drawing. And some people still actively use it, like with its smartphones line Note. Now Apple Pencil came out — does this mean that the stylus will soon enter our life? Completely. Vaughn is the same as Motorola returns to the market old phones with the new "filling".
Return whether an electronic pen is the right decision? This question can be viewed from two points of view. On the one hand, the stylus sometimes it really is not superfluous. I know a lot of people with large and thick fingers, which are difficult to get in small letters on the telephone keypad about the watch do not say. On the other, is that it looks a little ridiculous, like on the clock . But the fact that it can work, is impressive. Who knows, maybe Apple already is running with similar technology to the patent office?
best of all this stylus works on a smooth hand and about a hours
