One of the problems with using mobile devices such as iPhone or iPad is the need to keep the contents of the monitor secret. Users may need to view sensitive information such as financial data or medical details, but it is difficult to prevent others from glimpsing any data displayed on the screen in public places.

This seems to be achieved by setting up a physical barrier to hide the screen, or by actively blocking the view of others with one hand, but this nature attracts more unnecessary attention. Screen filters can also be used to block light from extreme viewing angles, although this may reduce the overall visual quality of major users.

In the patent application, Apple proposed a way to manipulate the display content in a document entitled "the encryption of the display depends on gazing" released by the Patent and Trademark Office on Thursday, so that only active users can know exactly what is displayed. At the same time, use false data to deceive other users.

The system takes Apple as the center and detects the user's line of sight on the device screen. In this way, the device will know exactly the real and accessible part of the graphical interface to be displayed or the content to be viewed on the display.

Knowing what the user is looking at can also tell the user what he has not noticed, and the system uses it to gain an advantage. In other displays that the user does not actively view, the system still displays images, but they contain useless and incomprehensible information that the observer cannot understand.

When the user changes the viewing position, the screen will be updated to find a new watching area, and the previously seen data will be overwritten by false content. In this way, users will always see what they want, but the data is only partially visible, so it is difficult for the outside world to actively read or understand.

In addition, Apple suggests that unreadable parts of the display may contain content that visually matches the rest of the display, but the information may be wrong. By making it visually similar to real information, it helps to further mask the user's current position on the screen and minimize the chance that bystanders are aware of some kind of visual encryption.

The document lists its inventors, Mohamed Agaolu, Chen Cheng, Hasha Sherahatti, Binger, Qin Shifan Jiang, Xi Aigor, Wu Jiaying and William Prager.

Apple files a large number of patent applications every week, but while applications and patents indicate Apple's research and development; d work is an area of concern, there is no guarantee that this idea will appear in future products or services.

Given Apple's history of encryption and privacy, it makes sense to draw opinions in the same area from Apple's research team. Unlike many other patent applications, it seems reasonable for Apple to launch something based on the idea of its current device.

In terms of feasibility, the current iPhone and iPad have the ability to deal with the content of a specific point by modifying the text or blurring the display. It can be said that the process of confusion is the simplest element of the whole concept.

The bigger challenge will be gaze detection, which Apple does perform in some way through Face ID's "attention awareness" feature. ARKit also includes elements for eye tracking, which may lead to gaze tracking in future frameworks.

In addition to the original camera array, people have been trying to use ordinary cameras for gaze detection for years, which may also help to achieve this goal. Using it on an ordinary user-oriented camera, you can make this feature run on an iPad that does not have such an advanced camera system.

There are other patent applications related to gaze testing, including those for using front-facing cameras since 2013. Other examples include an eye tracking system for head-mounted augmented reality displays using holographic elements, and ways to make virtual reality and augmented reality gaze detection faster and more accurate.
