Abstract: In one implementation, a method for visually indicating positional/rotational information of a finger-wearable device. The method includes: determining a set of translational values and a set of rotational values for the finger-wearable device, wherein the finger-wearable device is worn on a finger of a user; displaying, via a display, a visual representation of a location of the finger-wearable device based on the set of translational values; generating a visual representation of a grasp region of the user based on the set of translational values and the set of rotational values; and concurrently displaying, via the display, the visual representation of the grasp region with the visual representation of the location of the finger-wearable device.

Abstract: Methods and systems for displaying a computer generated image corresponding to the pose of a real-world object in a mixed reality system. The system may include of a head-mounted display (HMD) device, a magnetic track system and an optical system. Pose data detected by the two tracking systems can be synchronized by a timestamp that is embedded in an electromagnetic field transmitted by the magnetic tracking system. A processor may also be configured to calculate a future pose of the real world object based on a time offset based on the time needed by the HMD to calculate, buffer and generate display output and on data from the two tracking systems, such that the relative location of the computer generated image (CGI) corresponds with the actual location of the real-world object relative to the real world environment at the time the CGI actually appears in the display.

Abstract: Motion and/or rotation of an input mechanism can be tracked and/or analyzed to determine limits on a user's range of motion and/or a user's range of rotation in three-dimensional space. The user's range of motion and/or the user's range of rotation in three-dimensional space may be limited by a personal restriction for the user (e.g., a broken arm). The user's range of motion and/or the user's range of rotation in three-dimensional space may additionally or alternatively be limited by an environmental restriction (e.g., a physical object in a room). Accordingly, the techniques described herein can take steps to accommodate the personal restriction and/or the environmental restriction thereby optimizing user interactions involving the input mechanism and a virtual object.

Abstract: Disclosed are techniques for performing undo operations on holographic objects in an immersive 3D visual environment. A display system allows the user to undo a given user operation performed on a particular selected holographic object without affecting any other holographic objects, based on a user's gaze and/or other user input. The technique can be implemented in conjunction with a scrollable visual “timeline” in which multiple past states of the display environment are displayed to the user and are selectable by the user as the target state of the revert operation. Also disclosed is a technique for partially undoing a single continuous user action in a holographic display system.

Abstract: Disclosed are a method and corresponding apparatus to enable a user of a display system to manipulate holographic objects. Multiple holographic user interface objects capable of being independently manipulated by a user are displayed to the user, overlaid on a real-world view of a 3D physical space in which the user is located. In response to a first user action, the holographic user interface objects are made to appear to be combined into a holographic container object that appears at a first location in the 3D physical space. In response to the first user action or a second user action, the holographic container object is made to appear to relocate to a second location in the 3D physical space. The holographic user interface objects are then made to appear to deploy from the holographic container object when the holographic container object appears to be located at the second location.

Abstract: The exploitation of rolling back a system configuration to a previous system configuration is prevented by querying the update status of the system and comparing the received response with an expected response. If the comparison indicates that the update version of the system is older than the expected update version, the system is determined to have been rolled back. Accordingly, appropriate action is taken, such as sending a warning to the system, stopping the system from operating, disabling selected features, disconnecting the system from a network, banning the system from future connections to the network, and/or installing an update. The query can include a request for update version numbers of updates, times when updates were applied, predetermined questions, and an indication of the system (e.g., machine serial number, unique ID value).

Abstract: An individualized per device initialization of a computing device is unique relative to the initialization of other computing devices. A common initialization program, common to all computing devices of a particular type such as a game console, may be modified to be unique for each computing device. Modification may comprise the application of at least one individualized per device secret, e.g., key, to at least a portion of the common initialization program such as at least one initialization stage. Initialization is tied to one or more device specific identities. In this way, initialization vulnerabilities discovered on a particular device cannot be exploited en masse on other computing devices because each initialization program stored in each computing device is unique. The device specific nature of the initialization program may be extended to other information input to the computing device in order to prevent unauthorized sharing of information with other computing devices.

Abstract: A one-time-settable tamper resistant software repository may be used in any computing system to store system information such as security violations and policies for responding to them. A one-time-settable tamper resistant software repository may be cryptographically signed, encrypted with a per device key and accessible by only the most privileged software executed by a computing device, e.g., hypervisor or operating system kernel. A one-time-settable tamper resistant software repository may be mirrored in RAM for performance. Recordable event fields in a software repository may be one-time-settable without the ability to reset them in a field operation mode whereas they may be resettable in a different mode such as a manufacturing mode.
