A wide variety of electronic devices exist in the marketplace, and they have different capabilities for viewing and interacting with digital content. For example, PCs and laptops use a single flat panel display, which is often ideal for viewing traditional web pages that typically contain 2D content. However, such devices have limitations when it comes to viewing 3D content.
In contrast, mobile devices such as smartphones and tablets, as well as head-mounted displays, often have attributes and capabilities that are well suited for viewing 3D content. For example, users can simply hold their smartphone and change the view angle of 3D content by moving the orientation/position of the smartphone. Another example is that the head-mounted display itself contains multiple screens that provide the ability to present 3D content in stereo.
As can be seen, different electronic devices have different capabilities in viewing and interacting with digital content, and existing technologies and systems do not adequately facilitate the distribution, viewing and sharing of 2D and 3D content. To address this situation, Apple has filed a patent for an invention called “Detection and display of mixed 2d/3d content”.
The patent describes embodiments including a first device (e.g., a PC) capable of displaying 2D content referenced by a web page content item; and a second device in communication with the first device and capable of displaying 3D content referenced by a web page content item.
In one example, the first device displays 2D content of a web page and detects that the web page references 3D content associated with said 2D content. The second device links to or otherwise communicates with the first device and is capable of displaying the 3D content referenced by the web page. The first device determines that the second device should display the 3D content. After determining that the second device should display the 3D content, the second device receives the 3D content referenced by the web page from the first device or from another web page source, and then displays the 3D content.
In one example, the first device pre-downloads the 3D content and automatically sends the 3D content to the second device for display. In another example, the second device requests 3D content from the first device or from the web server hosting the web page or its 3D content.
After receiving the 3D content, the second device displays the 3D content. the display of the 3D content may utilize one or more features to render 3D content that does not support display by the first device. For example, the second device may display 3D content based on the user/device point of view through stereoscopic rendering or in a computer-generated reality environment.
In one implementation, the second device captures real-world images via a camera and uses the 3D content and the captured real-world images to construct a computer-generated environment.
When the user point of view or the device point of view changes, the second device changes the rendering of the 3D content accordingly.
In a simple example, a user can browse 2D web content, such as an online sofa, through a PC. If the sofa of the 2D web page is provided with a 3D model, the PC can communicate with a smartphone or headset and allow the user to visualize said sofa placed in the home through the smartphone or headset, as shown in the patent image above.
