This is particularly important for augmented reality applications, because the viewing system that superimposes digital objects on real-world scenes must ensure that the object is positioned in the user’s vision absolutely right. There are many different ways to track their location, including accelerometers and cameras pointing to the environment to track nearby objects. However, in the case of multiple people using the head-on vision system or the currently observed iPhone users using arkit applications, each device usually processes its own coordinate tracking system. In the process of using, the equipment will not share coordinates with each other, and generally work independently from each other. The location and motion 3D space of Apple glass smart glasses or VR or ar head display produced by Apple can be determined by sharing the data of local environment by other hardware. In a patent awarded Tuesday by the U.S. patent and trademark office called "e; synchronous augmented reality coordinate system and device "e;, apple proposed a method to share local location data for all devices by synchronizing data. The idea was initially that multiple items in the "e; feature set "e; were handed over by an electronic device to a second device, such as the iPhone or base station, to transmit data to the AR header. This feature set can include the reference position in 3D space, the coordinates of each device, and in some versions, maps of 3D space and points of interest therein, which can be used to place virtual objects. The second device can use the data as the starting point for the user to experience ar without drawing the region itself in advance. The second device can still collect its own data and update the feature set it receives, and at the same time, it can return the data to the first device, telling it the updated location and any other relevant data. Data back and forth handover allows other functions to be created, such as the first device providing the latest 3D map of an area based on the new location of the second device. Although the system has obvious application in AR and VR, such as guiding tourists to visit museums, this idea also has other ways of using, and it is not necessarily in a larger system. In terms of the description of the patent, it may help to enhance Apple glass, the rumored smart glasses, in another way. As data, including 3D map information, is transmitted between devices, it may be generated by iPhone or other devices and then passed on to Apple glass itself. In theory, this will reduce the amount of processing and sensors needed on Apple glass to be made in a less cumbersome and more attractive form. Apple will submit a large number of patent applications every week, but although the existence of the application indicates the areas of interest in Apple’s R & D work, it can not guarantee some function in the future products or services.
