In the process of using Surface Dial, some users may encounter this situation: When the Surface Dial is placed on the screen, the content of the screen below it will be hidden, causing inconvenience to the user. So, Microsoft's Patent came into being.
Microsoft made the following description of the device:
The patent consists of a touch screen, an image transmission structure, and a capacitance mark component. The image transmission structure can transmit a sensed optical image on the component by touching the screen component. In addition, the capacitive mark component can be sensed by the touch screen below it. In this way, the touch screen can display the image consistent with the image transmission device through the image transmission structure.
As can be seen from the description, Microsoft is planning to create (at least) partially transparent Surface Dial components. The Surface Dial with this design will have the image transmission function, can transfer the contents of the screen below it to the top for users to view The Surface Dial's base has capacitive components that can be sensed by the touch screen, so the contents of the screen remain consistent after being transmitted via the Surface Dial.
