The U.S. Patent and Trademark Office (USPTO) has published an "Applying Method and Apparatus for Editing Virtual Objects in a Real Environment" filed by Apple, which describes the use of advanced hardware and complex logic algorithms to insert virtual objects into the real world. , and methods for moving and deleting real objects in the real world.
This patent was filed by the German AR company Metaio in 2015 and then again in Germany in 2007. Metaio resubmitted the patent in the United States in 2010. After Apple acquired Metaio, the patent was transferred to Apple last November.
The patent describes a method of presenting a digital object in a real environment, mainly merging a computer-generated virtual object with a real-world image. Currently, one of the main challenges of AR technology is how to merge virtual objects with objects in the real world.
For example, overlaying virtual chairs into real-time video of a given environment requires high-precision positioning data, creation of boundaries, image scaling, and other technical considerations. Without proper hardware running complex software algorithms, images of virtual chairs may collide, perspective and geometric problems, or appear inappropriate.
Apple’s solutions use high-resolution cameras, powerful on-board image processors, and advanced positioning and location hardware. The iPhone currently on the market is already equipped with these components.
Specifically, this patent requires a camera or device to capture a two-dimensional image of the real environment and determine its position with respect to at least one object or component within the image. From there, the device uses depth mapping, radar, stereo cameras or other techniques to collect three-dimensional image information or spatial information, including the relative positioning of the floor and walls of its surroundings.
Next, the system divides or specifies a given area of ​​the two-dimensional environment. This split data will be used to merge the virtual object onto the displayed image while removing the selected portion of the real environment.
A Gan charger, also known as a GaN (Gallium Nitride) charger, is a type of power adapter that uses Gallium Nitride technology to provide high-efficiency charging for electronic devices. Gan chargers are known for their compact size, faster charging speeds, and reduced energy consumption compared to traditional chargers.
Gallium Nitride is a semiconductor material that allows for higher power density and better thermal management, enabling Gan chargers to deliver more power while generating less heat. This technology is particularly beneficial for fast-charging smartphones, tablets, laptops, and other devices.
Gan chargers typically feature multiple USB ports or other charging connectors, allowing users to simultaneously charge multiple devices. They are also compatible with various fast-charging protocols, such as Power Delivery (PD) and Quick Charge (QC), making them versatile for different devices.
Overall, Gan chargers offer a more efficient and convenient charging solution for modern electronic devices, providing faster charging times and reducing the number of chargers needed for multiple devices.
