Title:
DEVICES, METHODS, SYSTEMS, AND MEDIA FOR SELECTING VIRTUAL OBJECTS FOR EXTENDED REALITY INTERACTION
Document Type and Number:
WIPO Patent Application WO/2022/166448
Kind Code:
A1
Abstract:
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.
