Apple executive director Cook once said in an interview with ABC News that Apple is more optimistic about augmented reality. He explained that Augmented Reality allows people to be more familiar and sharing with each other, which in turn makes AR more commercially viable. While Apple discussed Augmented Reality, its competitor Microsoft has already taken the initiative to introduce the HoloLens augmented reality head-up display to the market.
Microsoft's patents have been increasing. In late January, the U.S. Patent and Trademark Office announced three Microsoft patents related to augmented reality. The first one is called "Grasping virtual objects in Augmented Reality"; the second patent is "Augmented reality system eye relief adjustment mechanism", which is related to another head-mounted system; the third patent is augmented reality related to Surface. Application, "Augmented reality light guide display".
1: Grasping virtual objects in Augmented Reality (grabbing virtual objects in an augmented reality environment)
Microsoft invented the patent number 9,552,673, which relates to an augmented reality system that allows virtual objects to be captured in an augmented reality environment. In various embodiments, the user's hand or other real object may be systematically tracked in an augmented reality environment. In the example, the shape of the real object is roughly estimated by at least two different types of particles, and the virtual object is updated according to the simulated force applied between the augmented reality environment and at least part of the particles. In various embodiments, the 3D position of the first type of particle (moving particle) is updated based on the real object, and the passive particle moves with the connected moving particle but does not penetrate the virtual object. In some examples, real-time photon flow processes are used to track the movement of real objects.

2: Augmented Reality Head Mounted System (Augmented Reality Headset System)
The second patent of Microsoft's invention is 9,557,569 and the title is "Augmented reality system eye relief adjustment mechanism". In this invention related to the head-mounted display system, Microsoft stated that the conventional head-mounted display usually uses hinged hinges and flat parts to adjust the appropriate eye size for different head sizes. This method is too bulky. It is difficult to manipulate and may be difficult to adapt to different users' head size and eye distance.
Failure to adapt to the size of the user's head may cause the head to be too tight and cause discomfort, or it may be too loose, which can negatively affect the user experience. Failure to maintain a proper line-of-sight distance may affect the user's perception of the augmented reality element.
Microsoft's solution is a head-mounted display system that includes an adjustable crown strap and a crown strap circumference adjustment mechanism. The system includes an armature made up of left and right arms, and the left and right arms are respectively mounted at their respective proximal ends to correspond to the left and right attachment structures of the head. In addition, displays are mounted at respective distal ends of the left and right arms, and an eye-movement mechanism is configured to move the right and left arms along a linear path toward and away from the band so that the user can adjust the eye clearance when wearing the band. .
FIG. 39 is a disassembled perspective view of the armature. FIG. 38 is a perspective view of an armature coupled to the head.
3: Augmented Reality Light Guide Display
The third patent invented by Microsoft is 9,558,590, entitled "Augmented Reality Light Guide Display."
Microsoft stated that their invention is related to augmented reality light guide display technology. In one or more real-time approaches, the device may include: a housing configured in a hand-held shape; one or more sensors configured to detect the position and orientation of the housing in the three-dimensional environment in the physical environment of the housing; at least partially transparent And a light guide display supported by the housing; an optical engine coupled to the light guide; and one or more modules disposed within the housing and at least partially implemented in hardware.
The one or more modules are configured to calculate the position and orientation of a reinforcement and allow the optical engine to output the reinforcement through the light guide to the display while at least a portion of the physical environment is viewable through the light guide.
As shown in FIG. 1 above, the input/output module #116 includes an augmented reality module #118. The augmented reality module #118 represents the function of the computing device/Surface tablet, using the display device #110 and enhancing the physical environment #112 through the Surface tablet. For example, in the example above, the Surface is in the environment of a finger #106 that includes three trees and the user's hand.
The augmented reality module is configured to output augments (eg, car 114) to be viewed in conjunction with the physical environment. To generate this view and know where to place the augmentation, the augmented reality module can utilize various techniques to determine the orientation and/or position of the Surface tablet relative to the physical environment. For example, the augmented reality module may utilize the camera #120 to capture an image of the physical environment. The augmented reality module can then process the image to locate one or more markers to determine how the Surface tablet is positioned, oriented, and moved.
These tags can take many forms. For example, the augmented reality module may set one or more viewpoints in the physical environment as markers and serve as a basis for determining direction and/or positioning, such as where the trunk stands on the ground. In another example, an augmented reality module may utilize views of one or more augmented reality tags located within the environment surrounding the Surface tablet. Therefore, items in the physical environment can serve as the basis for determining where Surface is located and how it is oriented.
We can see that Microsoft is working to solve all aspects of AR technology. Microsoft is very clear, or at least believe that this is an area where they can beat Apple.
Microsoft is rapidly establishing a beachhead to meet Apple and its operating system, hoping to defeat iOS and macOS on the Windows platform. Of course, it is still too early to judge whether their strategy will work. It ultimately depends on Apple. If you enter the market too late, they will find it harder to win developers. The current augmented reality market is developing rapidly. Xiaobian also hopes to see Apple's participation in the presence of many influxes. It is worth mentioning that Microsoft first entered the field of tablet PCs, but never really understood the road to success. Then Apple introduced the iPad and quickly became a consumer phenomenon.
Therefore, entering the market first does not always mean that the company has achieved much advantage. Of course, we cannot rule out that Microsoft is only thinking of defeating Apple, passing the advanced military market and making Apple struggle at the periphery. After all, when the iPhone appeared, it almost broke the entire kingdom of Microsoft. I think that Microsoft has learned a lesson and will challenge Apple in all aspects. I believe that in the next few years, the confrontation between Microsoft and Apple in the AR and AI areas will be very interesting. Apple and Windows fans never seem to really like each other, so the upcoming tech war will make the two camps quarrel for some time.
