Patent implication: Apple glasses may use wireless base station to reduce the burden of graphics processing

It house on August 26, the apple glasses rumored to be used indoors may adopt a completely wireless way to expand the communication range to multiple users in a room by using relay base stations. < / P > < p > at present, one of the problems in augmented reality and virtual reality systems is that they need to be close to a system for massive processing. A large amount of data from sensors on the head mounted display must be input into the computing device, and then the computing device must process it and apply the data to rendering virtual scenes or objects. Then, the video data must be transmitted to the display system for users to see. < p > < p > compact VR systems, such as Google cardboard and oculus go, solve this problem in an independent system by bringing all the processing process to the head display itself. However, doing so increases the weight on the user’s head. < / P > < p > early VR systems and packages, such as magic leap one, relied on binding the head display to a separate processing unit. This can take the form of small pocket devices, but usually desktop computers are used to improve graphics processing. Although this can improve the visual processing of the whole system and reduce the head display weight, the disadvantage is that there are cables that may trip or otherwise limit movement. < p > < p > in a patent granted by the U.S. patent and Trademark Office on Tuesday entitled “relay base and base station with directional wave formation based on location information”, apple wants to create a wireless cable head display that carries a battery pack for power supply, but the data is processed by wireless communication. < / P > < p > essentially, the system will rely on a relay base in the center of an area for VR or ar purposes, and it will also be wirelessly connected to a base station in another location. In a fixed setting, the base station and the relay base can be connected by cable, which may be feasible, but the main idea of the patent is about the communication between the relay base and the head display. < / P > < p > for systems with multiple relay bases in an area, such as a larger room, the base station will be connected to the nearest relay base between it and the target user. It is also possible for one docking station to process the user’s inbound communication while another can transmit data, for example, when the signal sent to the user may be blocked by the environment. < / P > < p > using the sensor combination on the head display, such as camera, accelerometer, gyroscope, camera and infrared sensor, the base uses the data to determine the position relationship between the user’s headset and it. The base can also have an infrared sensor, and the infrared mark on the head display can be used to help calculate the user’s position more accurately. < / P > < p > knowing the user’s location and their general movement allows the base station to send an amplified signal in a specific direction using the beamforming engine. Beamforming can minimize the power required to broadcast signals to users, and can also make signals more private through directionality. < / P > < p > it home understands that Apple files many patent applications every week. While the presence of applications indicates areas of interest for Apple’s R & D efforts, they do not guarantee that these ideas will appear in future products or services. For some time, Apple has been keen on improving VR or ar head display, but there are relatively few applications related to communication and portability.
