In December of last year, the U.S. Patent Office released Microsoft's AR patent that can achieve object tracking, but Microsoft's layout in the AR field is far more than that. Recently, the U.S. Patent Office successively passed three Microsoft AR patents.
Eye distance adjustment mechanism for AR system (patent number 9557569)
Different users have different head sizes and different eyes. If the head is too tight, it can cause discomfort to the user. The head is too loose, and it is easy to bring negative feelings to the user whether it is moving or standing. In addition, if the head-to-eye binocular spacing does not match the user's actual binocular spacing, it will affect the user's normal perception of the augmented reality element in the experience. The traditional head-mounted display is generally adjusted using a rotary hinge, but this method appears to be too bulky and cumbersome to operate.
Based on this situation, the solution described by Microsoft's patent includes an adjustable crown, which can be coupled to a head-mounted display and can be adjusted to fit the user's head. The system includes a left and right arm-containing armature, and the proximal ends of the left and right arms are respectively connected to the left and right sides of the corresponding attached parts of the head mounted display. The display screen is installed at the far end of the left and right arms of the system to adjust the proper distance between the eyes.
Crawl Virtual Objects in AR Environment (Patent No. 9552673)
The patent describes an AR system that can grab virtual objects in an augmented reality environment, such as stacking virtual cubes or using other physical manipulation tools to control virtual objects. In different application examples, the system can track the user's hand or other physical manipulation tools in the AR environment. For example, the shape of the physical manipulation tool is identified by at least two different types of particles, and the virtual object simulates update dynamics based on the external environment between the augmented reality environment and the particles. While the 3D position of the first type of particle (the moving particle) changes with the movement of the physical manipulation tool, the passively moving particle moves with the moving particle without penetrating the virtual object.
AR Light Guide Display (Patent No. 9558590)
People in daily life, whether it is work or tourism, are often in contact with electronic devices (computers, mobile phones, etc.), and based on traditional display technology, the user's exposure to electronic devices for too long can easily lead to eye fatigue. The AR light guide display presents a solution aimed at reducing the eyestrain of the user.
AR Light Guide Display Technology In one or more examples, such a device includes a hand-held housing, one or more sensors can detect the three-dimensional data (position and orientation) of the housing in physical space, a A light guide plate that is supported and at least partially transparent, a light engine that can be coupled to the light guide plate, one or more module processors mounted in the housing, and some necessary components.
