摘要： A head mounted display (HMD) device operating in a real world physical environment is configured with a sensor package that enables determination of an intersection of a device user's projected gaze with a location in a virtual reality environment so that virtual objects can be placed into the environment with high precision. Surface reconstruction of the physical environment can be applied using data from the sensor package to determine the user's view position in the virtual world. A gaze ray originating from the view position is projected outward and a cursor or similar indicator is rendered on the HMD display at the ray's closest intersection with the virtual world such as a virtual object, floor/ground, etc. In response to user input, such as a gesture, voice interaction, or control manipulation, a virtual object is placed at the point of intersection between the projected gaze ray and the virtual reality environment.

摘要： A method of constructing a swimming pool by laying a concrete shell of 80 mm thickness without any substantial reinforcement. A glass reinforced plastic of 5 mm thickness is then laid over the concrete once the concrete has cured. This particular combination between the fiberglass and the concrete shell allows the shell to crack and move in relation to the reinforced plastic layer, without transmitting any stresses to the reinforced plastic layer. This results in a pool which allows any stresses due to soil subsidence, movement, etc. to be transmitted to the concrete shell and not the reinforced plastic layer thereby leaving the plastic layer free of cracks.
摘要翻译：一种通过铺设80毫米厚度的混凝土外壳构建游泳池的方法，而没有任何实质的加固。一旦混凝土固化，然后将5 mm厚的玻璃钢塑料铺在混凝土上。玻璃纤维和混凝土外壳之间的这种特殊组合允许外壳相对于增强塑料层破裂和移动，而不会对增强塑料层传递任何应力。这导致一个池，其允许由于土壤沉降，运动等而导致的任何应力传递到混凝土壳体而不是增强塑料层，从而使塑料层没有裂缝。

摘要： In a virtual reality or mixed reality environment, an HMD device is configured to use surface reconstruction data points obtained with a sensor package to identify a location of a floor of a real world environment in which the device operates by sorting the data points by height into respective buckets where each bucket holds a different range of heights. A bucket having the greatest number of data points that are below the height of a user of the HMD device is used to identify the height of the real world floor, for example, by calculating an average of height values of data points in that bucket. A floor for the virtual reality environment may then be aligned to the identified height of the real world floor.

摘要： A head mounted display (HMD) device is configured with a sensor package that enables head tracking to determine the device user's proximity to holographic objects in mixed reality or virtual reality environments. A fade volume including concentrically-arranged volumetric shells is placed around the user including a near shell that is closest to the user, and a far shell that is farthest from the user. When a holographic object is beyond the far shell, the HMD device renders the object with full opacity (i.e., with no transparency). As the user moves towards a holographic object and it intersects the far shell, its opacity begins to fade out with increasing transparency to reveal the background behind it. The transparency of the holographic object increases as the object gets closer to the near shell and the object becomes fully transparent when the near shell reaches it so that the background becomes fully visible.

摘要： Methods for controlling an augmented reality environment associated with a head-mounted display device (HMD) are described. In some embodiments, a virtual pointer may be displayed to an end user of the HMD and controlled by the end user using motion and/or orientation information associated with a secondary device (e.g., a mobile phone). Using the virtual pointer, the end user may select and manipulate virtual objects within the augmented reality environment, select real-world objects within the augmented reality environment, and/or control a graphical user interface of the HMD. In some cases, the initial position of the virtual pointer within the augmented reality environment may be determined based on a particular direction in which the end user is gazing and/or a particular object at which the end user is currently focusing on or has recently focused on.

摘要： An HMD device renders a virtual reality environment in which areas of the real world are masked out so that real world objects such as computer monitors, doors, people, faces, and the like appear visible to the device user and no holographic or virtual reality content is rendered over the visible objects. The HMD device includes a sensor package to support application of surface reconstruction techniques to dynamically detect edges and surfaces of the real world objects and keep objects visible on the display as the user changes position or head pose or when the real world objects move or their positions are changed. The HMD device can expose controls to enable the user to select which real world objects are visible in the virtual reality environment.

摘要： A mixed-reality head mounted display (HMD) device supports a three dimensional (3D) virtual world application with which a real world desktop displayed on a monitor coupled to a personal computer (PC) may interact and share mouse input. A mouse input server executing on the PC tracks mouse movements on the desktop displayed on a monitor. When movement of the mouse takes it beyond the edge of the monitor screen, the mouse input server takes control of the mouse and stops mouse messages from propagating through the PC's system. The mouse input server communicates over a network connection to a mouse input client exposed by the application to inform the client that the mouse has transitioned to operating in the virtual world and passes mouse messages describing movements and control operation such as button presses.

摘要： An HMD device is configured to check the placement of newly introduced objects in a virtual reality environment such as interactive elements like menus, widgets, and notifications to confirm that the objects are significantly present within the user's field of view. If the intended original placement would locate the object outside the field of view, the HMD device relocates the object so that a portion of the object is viewable at the edge of the HMD display closest to its original placement. Such smart placement of virtual objects enables the user to readily discover new objects when they are introduced into the virtual reality environment, and then interact with the objects within a range of motions and/or head positions that is comfortable to support a more optimal interaction and user experience.
