Devices, methods, systems, and media are described for providing an extended screen distributed user interface in an augmented reality environment. GUI layout information for laying out a conventional 2D GUI is processed in order to generate an extended screen DUI for display partially on a 2D display device and partially on one or more virtual screens of an AR environment viewed using an AR display device, such as a head mounted display. GUI elements are laid out in the DUI based on a primary modality of the GUI element (input or output), and/or based on spatial dependencies between GUI elements encoded in the GUI layout information. Methods for switching focus between two software application instances displayed in the DUI are also disclosed.

Methods, devices, and processor-readable media for adjusting the control-display gain of a gesture-controlled device are described. Adjusting the control-display gain may facilitate user interaction with content or UI elements rendered on a display screen of the gesture-controlled device. The control-display gain may be adjusted based on a property of how a mid-air dragging gesture is being performed by a user's hand. The property may be the location of the gesture, the orientation of the hand performing the gesture, or the velocity of the gesture. A hand that becomes stationary for a threshold time period while performing the dragging gesture may adjust the control-display gain to a different level. Control-display gain may be set to a different value based on the current velocity of the hand performing the gesture. The control-display gain levels may be selected from a continuous range of values or a set of discrete values. Devices for performing the methods are described.

The present disclosure describes systems and methods for providing driver assistance. A current vehicle state of a vehicle at a current timestep and an environment map representing an environment of the vehicle at least at the current timestep are obtained. Augmented reality feedback is generated including a virtual vehicle representing a predicted future vehicle state, where the predicted future vehicle state is predicted for a given future timestep based on at least one of the current vehicle state or the current environment. The generated augmented reality feedback including the virtual vehicle is outputted to be displayed by a display device.

Systems and methods for prediction-based driver assistance

Methods and systems for selecting an object or location in an extended reality (XR) environment or physical environment are described. A first origin, including a first position and a first direction, and a second origin, including a second position and a second direction, are obtained by at least one sensor. An intersection of a first ray, casted from the first origin, and a second ray, casted from the second origin, is determined. A selected object or selected location is identified, based on the determined intersection. An identification of the selected object or the selected location is outputted.

Methods and systems for selection of objects

Devices, methods, systems, and media are described for selecting virtual objects for user interaction in an extended reality environment. Distant virtual objects are brought closer to the user within a virtual 3D space to situate the selected virtual object in virtual proximity to the user's hand for direct manipulation. A virtual object is selected by the user based on movements of the user's hand and/or head that are correlated or associated with an intent to select a specific virtual object within the virtual 3D space. As the user's hand moves in a way that is consistent with this intent, the virtual object is brought closer to the user's hand within the virtual 3D space. To predict the user's intent, hand and head trajectory data may be compared to a library of kinematic trajectory templates to identify a best-matched trajectory template.
