Apple Glasses will superimpose virtual screens on iOS devices in the future to enhance privacy

        Apple's iPhone and iPad can provide a privacy screen, where only the wearer of "Apple Glasses" can see the information on the screen through augmented reality technology. Apple has repeatedly said that privacy is not some additional additional feature, it has been built in from the beginning, and it seems to be proving this with the upcoming "Apple Glasses". New patent applications show that Apple is exploring how to use Apple AR to effectively create more ways to protect privacy.

　　"Privacy Screen" is a new patent application that proposes a restriction that makes the screen invisible to anyone but the device owner. It is specifically intended to get rid of the need for a polarized screen cover to avoid viewing angle issues. Traditional privacy screens attenuate some light in a direction perpendicular to the display, thereby reducing the brightness perceived by the user. To compensate, users may remove the privacy screen when they are not concerned about privacy. In this case, the user must store, transport and reinstall the privacy screen, and these screens sometimes cause the device to increase brightness to compensate, which then reduces battery life. On top of that, the screen makes it difficult to see clearly, which obviously affects battery life, and it still does not prevent everyone from seeing the screen content.

　　Apple's patent application eliminates the practice of placing a screen on an iPad or iPhone, and instead uses AR and "Apple Glasses". Although different methods are described in the application, the main one is a method of presenting information on glasses. Apple stated in the patent that if you are wearing "Apple Glasses" and you look at your iPad screen, AR will make you feel that there is a normal display on the device. To people around you or even those behind you, the iPad can look completely blank. In addition to passively displaying information for reading, the AR system also makes people feel that the controls are on the iPad screen. The iPad can then record the user's clicks on these controls. The result is that to people around you, it seems like you are randomly clicking on a blank screen. But to you, it's like you are using a normal iPad or iPhone.
