An artificial reality system is described that renders, presents, and controls user interface elements within an artificial reality environment, and performs actions in response to one or more detected gestures of the user. The artificial reality system can include a menu that can be activated and interacted with using one hand. In response to detecting a menu activation gesture performed using one hand, the artificial reality system can cause a menu to be rendered. A menu sliding gesture (e.g., horizontal motion) of the hand can be used to cause a slidably engageable user interface (UI) element to move along a horizontal dimension of the menu while horizontal positioning of the UI menu is held constant. Motion of the hand orthogonal to the menu sliding gesture (e.g., non-horizontal motion) can cause the menu to be repositioned. The implementation of the artificial reality system does require use of both hands or use of other input devices in order to interact with the artificial reality system.

An artificial reality system is described that renders, presents, and controls user interface elements within an artificial reality environment, and performs actions in response to one or more detected gestures of the user. In one example, an artificial reality system comprises an image capture device configured to capture image data representative of a physical environment; a head-mounted display (HMD) configured to output artificial reality content; a gesture detector configured to identify, from the image data, a gesture comprising a motion of two fingers from a hand to form a pinching configuration and a subsequent pulling motion while in the pinching configuration; a user interface (UI) engine configured to generate a UI input element in response to identifying the gesture; and a rendering engine configured to render the UI input element as an overlay to at least some of the artificial reality content.

Detecting input in artificial reality systems based on a pinch and pull gesture

The present technology relates to artificial reality systems. Such systems provide projections a user can create to specify object interactions. For example, when a user wishes to interact with an object outside her immediate reach, she can use a projection to select, move, or otherwise interact with the distant object. The present technology also includes object selection techniques for identifying and disambiguating between objects, allowing a user to select objects both near and distant from the user. Yet further aspects of the present technology include techniques for interpreting various bimanual (two-handed) gestures for interacting with objects. The present technology further includes a model for differentiating between global and local modes for, e.g., providing different input modalities or interpretations of user gestures.

Automatic projection type selection in an artificial reality environment

An artificial reality system is described that renders, presents, and controls user interface elements within an artificial reality environment, and performs actions in response to one or more detected gestures of the user. In one example, an artificial reality system comprises a head-mounted display configured to output artificial reality content; a stylus; a stylus action detector configured to detect movement of the stylus, detect a stylus selection action, and after detecting the stylus selection action, detect further movement of the stylus; a UI engine configured to generate stylus movement content in response to detecting movement of the stylus, and generate a UI input element in response to detecting the stylus selection action; and a rendering engine configured to render the stylus movement content and the UI input element as overlays to the artificial reality content, and update the stylus movement content based on the further movement of the stylus.

A method and apparatus are for movement analysis. The apparatus and method receive acceleration data from an accelerometer (or measurements from other motion sensors) that is carried by a user. The acceleration data is divided into epochs and a determination is made as to whether the user is walking or running within each epoch. Consecutive epochs in which the user is found to be walking may be concatenated to determine periods of time during which the user is walking or running. An initial estimate of the time that the user starts to walk or run and stops walking or running are determined for each period of walking. An iterative optimization process is then performed to determine accurate start and stop times for the period of walking or running.

Movement analysis method and apparatus

An apparatus and method determine movement information for a user that carries an accelerometer whilst moving. The apparatus receives acceleration data from the accelerometer defined relative to a frame of reference of the accelerometer. A transformation is determined and applied to the acceleration data or to data derived from the acceleration data to determine acceleration data is a user frame of reference that includes a user direction of travel and a side to side direction transverse to the user direction of travel. The acceleration data or data derived from the acceleration data is analyzed to determine a time period corresponding either to a user stride period or to a step period as the user is walking or running; and information about accelerations in the side to side direction are used to disambiguate whether the determined time period corresponds to the user stride period or to the user step period.

Projection casting in virtual environments

Global and local mode virtual object interactions

A progressive display system can compute a virtual distance between a user and virtual objects. The virtual distance can be based on: a distance between the user and an object, a viewing angle of the object, and/or a footprint of the object in a field of view. The progressive display system can determine where the virtual distance falls in a sequence of distance ranges that correspond to levels of detail. Using a mapping between content sets for the object and levels of detail that correspond to distance ranges, the progressive display system can select content sets to display in relation to the object. As the user moves, the virtual distance will move across thresholds bounding the distance ranges. This causes the progressive display system to select and display other content sets for the distance range in which the current virtual distance falls.

An artificial reality system is described that renders, presents, and controls user interface elements within an artificial reality environment, and performs actions in response to one or more detected gestures of the user. The artificial reality system includes an image capture device configured to capture image data representative of a physical environment, a head-mounted display (HMD) configured to output artificial reality content, a gesture detector configured to identify, from the image data, a gesture comprising a configuration of a hand that is substantially stationary for at least a threshold period of time and positioned such that a thumb of the hand and at least one other finger form approximately a circle or approximately a circular segment, a user interface (UI) engine to generate a UI element in response to the identified gesture, and a rendering engine to render the UI element as an overlay to the artificial reality content.

Artificial reality systems with hand gesture-contained content window

The disclosed computer-implemented method may include communicatively coupling a user interface device to a virtual reality device, capturing inputs from a user on the user interface device, displaying, on the virtual reality device, a virtual representation of the captured inputs from the user, and mirroring, on the virtual reality device, content presented on the user interface device. Various other methods, systems, and computer-readable media are also disclosed.

Devices, systems, and methods for virtual representation of user interface devices

A hand interaction system can use a three-state model to differentiate between normal hand movements, such as reaching for an object, and hand input gestures. The three-state model can specify a sequence of states including: 1) a neutral state, 2) a tracking state, and 3) an active state. In the neutral state, the hand interaction system monitors for a gesture signaling a transition to the tracking state but does not otherwise interpret a gesture corresponding to the active state as input. Once a gesture causes a transition to the intermediate tracking state, the hand interaction system can recognize a further active state transition gesture, allowing active state interaction. Thus, the monitoring for the intermediate tracking state provides a gating mechanism, making it less likely that the hand interaction system will interpret hand movements as input when not so intended by the user.
