Augmented reality systems are similar to virtual reality systems but, instead of immersing someone in a different reality, augmented reality helps users in the real world. Headset- or glasses-based augmented reality systems change the user’s worldview and are usually more immersive than other types.
Anchoring virtual images to real world surfaces in augmented reality systems
ActiveUS20120249741A1Television system detailsColor television detailsSensor arrayAugmented reality systems
A head mounted device provides an immersive virtual or augmented reality experience for viewing data and enabling collaboration among multiple users. Rendering images in a virtual or augmented reality system may include capturing an image and spatial data with a body mounted camera and sensor array, receiving an input indicating a first anchor surface, calculating parameters with respect to the body mounted camera and displaying a virtual object such that the virtual object appears anchored to the selected first anchor surface. Further operations may include receiving a second input indicating a second anchor surface within the captured image that is different from the first anchor surface, calculating parameters with respect to the second anchor surface and displaying the virtual object such that the virtual object appears anchored to the selected second anchor surface and moved from the first anchor surface.

Dynamic vergence and focus control for head-mounted displays
Systems and methods for dynamically controlling vergence and focus for a see-through head-mounted display (ST-HMD) used as part of an augmented reality (AR) system are disclosed. The ST-HMD (40) allows a user (30) to view left and right images (150L, 150R) through corresponding left and right eyepieces (104L, 104R) so that a single virtual object (150V) based on the right and left images as seen at a real object such as a screen (20). When the user moves relative to the real object, however, the vergence changes and the virtual object does not appear in focus at the real object. Changes in the vergence are compensated by tracking the user's head position with a tracking unit (350) and providing the tracking data to a controller (180). Based on the tracking data and the interpupilary distance (IPD) of the user, the controller calculates the offset (H) needed to be imparted to the images formed in the eyepieces to maintain the vergence of the virtual object at the real object even when the user's position changes relative to the real object.

Augmented reality system for position identification
A system, method, and computer program product for automatically combining computer-generated imagery with real-world imagery in a portable electronic device by retrieving, manipulating, and sharing relevant stored videos, preferably in real time. A video is captured with a hand-held device and stored. Metadata including the camera's physical location and orientation is appended to a data stream, along with user input. The server analyzes the data stream and further annotates the metadata, producing a searchable library of videos and metadata. Later, when a camera user generates a new data stream, the linked server analyzes it, identifies relevant material from the library, retrieves the material and tagged information, adjusts it for proper orientation, then renders and superimposes it onto the current camera view so the user views an augmented reality.

Augmented reality system for displaying patient data
ActiveUS20180300919A1Small sizeReduce contentMedical simulationImage enhancementAugmented reality systems
System and methods are provided for augmented reality displays for medical and physiological monitoring. Augmented reality user interfaces are virtually pinned to a physical device, a location, or to a patient. An augmented reality position determination process determines the presentation of user interfaces relative to reference positions and reference objects. Detection of gestures causes the augmented reality users interfaces to be updated, such as pinning a user interface to a device, location, or patient. Looking away from an augmented reality user interface causes the user interface to minimize or disappear in an augmented reality display. An augmented reality gesture detection process determines gestures based on captured image data and computer vision techniques performed on the image data.

Fast object detection for augmented reality systems
InactiveUS20060233423A1Reduce dimensionalityMinimize impactImage analysisCharacter and pattern recognitionVisibilityViewpoints
A detection method is based on a statistical analysis of the appearance of model patches from all possible viewpoints in the scene, and incorporates 3D geometry during both matching and pose estimation processes. By analyzing the computed probability distribution of the visibility of each patch from different viewpoints, a reliability measure for each patch is estimated. That reliability measure is useful for developing industrial augmented reality applications. Using the method, the pose of complex objects can be estimated efficiently given a single test image. In a fast method to detect objects in a given image or video sequence, a series of hierarchical feature descriptors permit balancing between the complexity of feature extraction and cost of combinatorial matching. The feature descriptors are derived from the 3D model of the object of interest along with the available calibrated real-life images or videos. The variability of the real-life images defines the granularity of the feature descriptors.
