Apple is continuing to refine the concept of & quot; Apple glasses, an augmented reality wearable device, and how to use the iPhone as a head mounted display. This is not to say that Apple sees the iPhone as a potential alternative to & quot; Apple Glasses & quot; but rather that it is looking for ways to leverage users’ existing devices. The head mounted display device, called & quot; for holding portable electronic devices with a display screen & quot; is Apple’s latest patent application, in which Apple has studied the benefits of doing so. This is not the first time Apple has studied this issue. < p > < p > Apple said in its patent that with a headset, users can view the media provided by portable electronic devices. Such a configuration allows users to view media on a private display screen, while the media is provided by a personal handheld device.

In addition, it can reduce the cost of the whole system of Apple glasses Cost, size, weight and complexity. < / P > < p > the patent application actually discusses many different configurations, using the iPhone iPod as the source of the video or image being watched. However, each configuration involves the production of a system that temporarily integrates or merges head mounted devices and portable electronic devices, both mechanically and electronically. < / P > < p > one of the descriptions in Apple’s patent application is aimed at simply inserting iPhone into Apple’s eyeglass device. Other parts of the patent relate to how an iPhone or other device recognizes a connected head mounted display, including automatically adjusting the image content displayed on the screen for close viewing.
