Methods for generating and displaying people-triggered holographic reminders are described. In some embodiments, a head-mounted display device (HMD) generates and displays an augmented reality environment to an end user of the HMD in which reminders associated with a particular person may be displayed if the particular person is within a field of view of the HMD or if the particular person is within a particular distance of the HMD. The particular person may be identified individually or identified as belonging to a particular group (e.g., a member of a group with a particular job title such as programmer or administrator). In some cases, a completion of a reminder may be automatically detected by applying speech recognition techniques (e.g., to identify key words, phrases, or names) to captured audio of a conversation occurring between the end user and the particular person.

Technology is described for web-like hierarchical menu interface which displays a menu in a web-like hierarchical menu display configuration in a near-eye display (NED). The web-like hierarchical menu display configuration links menu levels and menu items within a menu level with flexible spatial dimensions for menu elements. One or more processors executing the interface select a web-like hierarchical menu display configuration based on the available menu space and user head view direction determined from a 3D mapping of the NED field of view data and stored user head comfort rules. Activation parameters in menu item selection criteria are adjusted to be user specific based on user head motion data tracked based on data from one or more sensors when the user wears the NED. Menu display layout may be triggered by changes in head view direction of the user and available menu space about the user's head.

Technology is described for (3D) space carving of a user environment based on movement through the user environment of one or more users wearing a near-eye display (NED) system. One or more sensors on the near-eye display (NED) system provide sensor data from which a distance and direction of movement can be determined. Spatial dimensions for a navigable path can be represented based on user height data and user width data of the one or more users who have traversed the path. Space carving data identifying carved out space can be stored in a 3D space carving model of the user environment. The navigable paths can also be related to position data in another kind of 3D mapping like a 3D surface reconstruction mesh model of the user environment generated from depth images.

Methods for recognizing gestures using adaptive multi-sensor gesture recognition are described. In some embodiments, a gesture recognition system receives a plurality of sensor inputs from a plurality of sensor devices and a plurality of confidence thresholds associated with the plurality of sensor inputs. A confidence threshold specifies a minimum confidence value for which it is deemed that a particular gesture has occurred. Upon detection of a compensating event, such as excessive motion involving one of the plurality of sensor devices, the gesture recognition system may modify the plurality of confidence thresholds based on the compensating event. Subsequently, the gesture recognition system generates a multi-sensor confidence value based on whether at least a subset of the plurality of confidence thresholds has been satisfied. The gesture recognition system may also modify the plurality of confidence thresholds based on the plugging and unplugging of sensor inputs from the gesture recognition system.
摘要:
Methods for enabling hands-free selection of objects within an augmented reality environment are described. In some embodiments, an object may be selected by an end user of a head-mounted display device (HMD) based on detecting a vestibulo-ocular reflex (VOR) with the end user's eyes while the end user is gazing at the object and performing a particular head movement for selecting the object. The object selected may comprise a real object or a virtual object. The end user may select the object by gazing at the object for a first time period and then performing a particular head movement in which the VOR is detected for one or both of the end user's eyes. In one embodiment, the particular head movement may involve the end user moving their head away from a direction of the object at a particular head speed while gazing at the object.

Methods for positioning virtual objects within an augmented reality environment using snap grid spaces associated with real-world environments, real-world objects, and/or virtual objects within the augmented reality environment are described. A snap grid space may comprise a two-dimensional or three-dimensional virtual space within an augmented reality environment in which one or more virtual objects may be positioned. In some embodiments, a head-mounted display device (HMD) may identify one or more grid spaces within an augmented reality environment, detect a positioning of a virtual object within the augmented reality environment, determine a target grid space of the one or more grid spaces in which to position the virtual object, determine a position of the virtual object within the target grid space, and display the virtual object within the augmented reality environment based on the position of the virtual object within the target grid space.
摘要:
A system for generating an augmented reality environment in association with one or more attractions or exhibits is described. In some cases, a see-through head-mounted display device (HMD) may acquire one or more virtual objects from a supplemental information provider associated with a particular attraction. The one or more virtual objects may be based on whether an end user of the HMD is waiting in line for the particular attraction or is on (or in) the particular attraction. The supplemental information provider may vary the one or more virtual objects based on the end user's previous experiences with the particular attraction. The HMD may adapt the one or more virtual objects based on physiological feedback from the end user (e.g., if a child is scared). The supplemental information provider may also provide and automatically update a task list associated with the particular attraction.
摘要:
Assisted viewing of web-based resources by an end user of a head-mounted display device (HMD) is described. An HMD may display content from web-based resources using a see-through display while tracking eye and head movement of the end user viewing the content within an augmented reality environment. Active view regions within the see-through display are identified based on tracking information including eye gaze data and head direction data. The web-based resources are analyzed to identify content and display elements. The analysis is correlated with the active view regions to identify the underlying content that is a desired point of focus of a corresponding active view region, as well as to identify the display elements corresponding to that content. A web-based resource is modified based on the correlation. The content from the web-based resource is displayed based on the modifications to assist the end user in viewing the web-based resource.
