Touch screen technology innovation from the evolution of mobile phone function, IT products into the era of intelligent chip. The screen, camera, etc. have become promote intelligent process the main IT products. But many people have not noticed, touch technology is constantly updated, we can continue the product in the hands of lighter, thinner and more the main reason is more intelligent. The way of human-computer interactive touch technology to constantly upgrade.

The earliest human-computer interaction through the button, mouse and other physical devices, touch screen technology innovation into the touch of our physical buttons continue to decrease, even all the operation through the virtual keys to achieve products. Now touch technology upgrade, so that the user can through various efforts, multi touch gestures, etc. the way to realize, usually need complicated operation functions.

There is no doubt that touch is the man-machine interactive way the habits of the people at this stage. It is natural, efficient and accurate. Although the technology of speech recognition and somatosensory interaction over time are becoming more mature, but in a short time it is difficult to see what kind of interaction can be like that touch universal and stable.

When a finger touch screen technology innovation is operating on the screen, to calculate the touch position by the amount of current, so if you are wearing gloves and water, because the glove is an insulator (except for some special materials and gloves), water is a good conductor touch caused problems.

The scheme to solve this problem: water is conductive, but for some special water capacitance screen, we have a very advanced algorithm can detect contact in a screen what is water or human fingers. We sort out things different, together that tracking in the end, is caused by water or finger caused. You just said that the special material can be conductive gloves, can be used in apple. Actually also in our equipment, but we can also use normal gloves, why? Because normal gloves to screen in the contact process. There is a small distance, can produce electrical signals. We can also use this signal classification, our technique can separate operation, is in the glove mode, using the device, or in the case of a bare finger Operation, can accurately judge, so can also be used according to the use of a lot of people

So how does insulation produce signals?

Normal gloves or ski gloves, cloth gloves are insulated, it can be seen as will have an influence on the electric field, with your fingers to directly contact the touch screen is not the same as touch, which is a layer of insulating layer, just like your suspension touch is the same, but it will still change the electric field on the whole, still will influence the distribution of electric field, we can distinguish between different algorithms. And the insulator on the electric field change is not the same.

The dielectric constant is not the same, so that the electric field effect is not the same, so we can distinguish the algorithm in a range, the conductor and insulator within the range of what you're wearing gloves, we basically are insulated gloves are able to do is touch, because now the most thick gloves but 4 mm, you lift a finger, we can still on the electric field on the touch screen, aware of our chip can be done.

In fact, the principle of capacitive touch surface electric field is distributed, when your fingers up, even if you close it, have the effect, after you touch up is the biggest impact. After you wear gloves, this signal will become very weak, the design and algorithm of this time will distinguish between chips. Then put your fingers to catch these weak signal.

A wet finger or water vapor, water vapor is actually a conductor, if I put a drop of water on the touch screen, you can use it as a conductor, especially when the finger stopped at the top, is such an action. Because the dielectric constant of the fingers of the dielectric constant and water is not the same.

Suspension technology is the use of gloves, in fact, gloves are also the case, there is a layer of insulation between the finger and the touch screen, the suspension is to lift it up, the air is an insulator
