After four generations of development, Microsoft's Surface series has become the mouthpiece of the Windows tablet, and it has even begun to encroach on the market share of the iPad in foreign countries. A major feature of Surface is its Surface Pen stylus. Because of the inherent advantages of the Windows platform, Surface Pen can be easily used to complete lightweight production drawing work.

Recently, a black technology patent of Microsoft was exposed. This technical patent numbered # 20160048221A1 shows a "digital stylus" that can take colors of real objects like a PhotoShop color picker, and then extract colors to the screen for use. In plain English, this pen can sense the color of the physical world.

The pen on the patent map is equipped with up and down scroll, menu and confirmation keys. It has its own LED light and display. The pen can transmit the collected data to TV, tablet, computer, mobile phone and other devices through the network.

Mozbii stylus

In fact, there were products with similar functions such as Mozbii stylus before, but the Surface Pen is much better in appearance and practical use.

In addition to the Surface series, this function may also be used on Microsoft's virtual reality glasses HoloLens. After all, the virtual reality attribute of this function is too strong. You can imagine taking down the color of a flower with this pen and then painting and painting from the perspective of HoloLens. This experience is a little exciting.
