摘要： Systems and methods for implementing methods for user selection of a virtual object in a virtual scene. A user input may be received via a user input device. The user input may be an attempt to select a virtual object from a plurality of virtual objects rendered in a virtual scene on a display of a display system. A position and orientation of the user input device may be determined in response to the first user input. A probability the user input may select each virtual object may be calculated via a probability model. Based on the position and orientation of the user input device, a ray-cast procedure and a sphere-cast procedure may be performed to determine the virtual object being selected. The probability of selection may also be considered in determining the virtual object. A virtual beam may be rendered from the user input device to the virtual object.

摘要： Systems and methods for replacing a 2D image with an equivalent 3D image within a web page. Content of a 2D image displayed within a web page may be identified and 3D images may be identified as possible replacements of the 2D image. The 3D images may be ranked based on sets of ranking criteria. A 3D image with a highest-ranking value may be selected based on a ranking of the 3D images. The selected 3D image may be integrated into the web page, thereby replacing the 2D image with the selected 3D image. Further, a user input manipulating the 3D image within the web page may be received. The user input may include movement of a view point of a user relative to a display displaying the web page and/or detection of a beam projected from an end of a user input device intersecting with the 3D image.

摘要： Systems and methods for enhancing trackability of a passive stylus. A six degree of freedom (6 DoF) location and orientation of a passive stylus may be tracked by a tracking system via a retroreflector system disposed on the passive stylus. Additionally, characteristic movements of one of a user's finger, hand, and/or wrist may be recognized by the tracking system. The passive stylus may useable to interact with a virtual 3D scene being displayed via a 3D display. A user input via the passive stylus may be determined based on the tracked 6 DoF location and orientation of the passive stylus and/or the recognized characteristic movements. The retroreflector system may include multiple patterns of retroreflectors and one of the patterns may be a spiral pattern of retroreflectors disposed along a longitudinal axis of the passive stylus.

摘要： Systems and methods for replacing a 2D image with an equivalent 3D image within a web page. The 2D image displayed within a web page may be identified and a 3D image with substantially equivalent content may also be identified. The 3D image may be integrated into the web page as a replacement to the 2D image. Further, at least one user input manipulating the 3D image within the web page may be received. The at least one user input may include movement of a view point (or point of view) of a user relative to a display displaying the web page and/or detection of a beam projected from an end of a user input device (and/or an end of the user input device) intersecting with the 3D image.
