As Microsoft's Windows updates faster and faster, the number of laptops equipped with touch screens has increased since Win8, and the introduction of Windows 10 has blurred the boundary between laptops and tablets. However, some old users' laptops are not upgraded in a timely manner. They are still traditional ordinary screens, not to mention Apple's Mac users. This gadget introduced today, AirBar, can make your old notebook change, and the screen instantly supports touch control.

The product launched by this Swedish manufacturer is ugly. It is almost a black strip of USB cable, which is simply marked with the product name and some parameters. Similar to the USB accessories we use now, plug and play without any extra settings.

According to the introduction on the official website, in order to realize the touch function, Neonode's zForce AIR is used ™ Technology is different from the capacitive touch technology that people use everyday, zForce AIR ™ It is an optical touch technology. The specific point is that the touch point is sensed by emitting infrared light and receiving light refractive index, so that the screen that does not support touch can become a "touch screen" after adding this widget.

Because the principle is different from capacitive touch, the AirBar can be used normally when wearing gloves or holding other things. The manufacturer also specially supports the touch gestures of Win8 and Win10. In terms of system, Windows, Linux and OS X can all support it, but now OS X functions are not perfect.

It may be due to the difficulty of technology or mass production. For the time being, there is only a 15.6-inch AirBar for pre-sale at a price of $49. This magical gadget can make the notebook instantly support touch. I wonder if you are going to start with it?
