摘要： A technique is described herein for using a parent computing device and at least one companion computing device to simultaneously interact with an environment. In one implementation, the parent computing device progressively builds parent map information through its interaction with the environment. The technique leverages the parent map information to identify a current pose of the companion computing device. In one case, for instance, the parent computing device sends the parent map information to the companion computing device, and the companion computing device determines its current pose based on the parent map information in conjunction with sensor information collected by the companion computing device.

摘要： In various embodiments, methods and systems for implementing integrated free space and surface inputs are provided. An integrated free space and surface input system includes a mixed-input pointing device for interacting and controlling interface objects using free space inputs and surface inputs, trigger buttons, pressure sensors, and haptic feedback associated with the mixed-input pointing device. Free space movement data and surface movement data are tracked and determined for the mixed-input pointing device. An interface input is detected for the mixed-input pointing device transitioning from a first input to a second input, such as, from a free space input to a surface input or from the surface input to the free space input. The interface input is processed based on accessing the free space movement data and the surface movement data. An output for the interface input is communicated from the mixed-input pointing device to interact and control an interface.

摘要： A system determines the transmission strength of the magnetic field signal. The magnetic field signal is transmitted from a first magnetic-sensor device to a second magnetic-sensor device. The system then determines a first projected distance between the first magnetic-sensor device and the second magnetic-sensor device. Based at least in part on the first projected distance, the system calculates an adjusted transmission strength for the magnetic field signal. The system then causes the first magnetic-sensor device to transmit an adjusted magnetic field signal. The adjusted magnetic field signal comprises the adjusted transmission strength. The system receives, from the second magnetic-field device, the adjusted magnetic field signal. Based at least in part upon the received adjusted magnetic field signal, the system, computes a first pose of the first magnetic-sensor device in relation to the second magnetic-sensor device.

摘要： A method of detecting eye location for a head-mounted display system includes directing positioning light to an eye of a user and detecting the positioning light reflected from the eye of the user. The method further includes determining a distance between the eye and a near-eye optic of the head-mounted display system based on attributes of the detected positioning light, and providing feedback for adjusting the distance between the eye and the near-eye optic.

摘要： A mixed-reality system causes a magnetic transmission device to transmit a magnetic field signal. The mixed-reality system also causes a magnetic-field sensing device to determine a measurement of the magnetic field signal. The mixed-reality system then identifies, using one or more input devices, that a magnetically-interfering object is located within a same environment as both the magnetic transmission device and the magnetic-field sensing device. The mixed-reality system also determines one or more characteristics of magnetic field interference that the magnetically-interfering object is imparting on the magnetic transmission device or the magnetic-field sensing device. The mixed-reality system then computes an adjustment to a pose-estimation model based upon the one or more characteristics of magnetic field interference. The pose-estimation model is used to calculate a pose of at least one of the magnetic transmission device or the magnetic-field sensing device.

摘要： An apparatus for dynamically determining a displacement of a target sensor in an electronic system is disclosed. The apparatus can comprise a non-line-of-sight sensor rigidly mounted on or proximate to the target sensor and configured to measure a parameter that varies with the displacement of the target sensor. The apparatus further can comprise at least one processor coupled to the non-line-of-sight sensor and configured to compute the displacement of the target sensor based on the parameter, and to compute an adjustment value based on the computed displacement.

摘要： Embodiments are described herein for determining a stabilization plane to reduce errors that occur when a homographic transformation is applied to a scene including 3D geometry and/or multiple non-coplanar planes. Such embodiments can be used, e.g., when displaying an image on a head mounted display (HMD) device, but are not limited thereto. In an embodiment, a rendered image is generated, a gaze location of a user is determined, and a stabilization plane, associated with a homographic transformation, is determined based on the determined gaze location. This can involve determining, based on the user's gaze location, variables of the homographic transformation that define the stabilization plane. The homographic transformation is applied to the rendered image to thereby generate an updated image, and at least a portion of the updated image is then displayed.
