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.

The 3D image may include at least one object. The method may include tracking a position and an orientation of an input device in open space in relation to the 3D image. The method may include assessing a handedness of a user based on the position and the orientation of the input device with respect to at least one of the objects. In some embodiments, the method may include configuring at least a portion of the 3D image based upon the assessed handedness. The at least a portion of the 3D image may include interactive menus. In some embodiments, the method may include configuring at least a portion of an interactive hardware associated with the system based upon the assessed handedness.

摘要： In some embodiments, a system for tracking with reference to a three-dimensional display system may include a display device, an image processor, a surface including at least three emitters, at least two sensors, a processor. The display device may image, during use, a first stereo three-dimensional image. The surface may be positionable, during use, with reference to the display device. At least two of the sensors may detect, during use, light received from at least three of the emitters as light blobs. The processor may correlate, during use, the assessed referenced position of the detected light blobs such that a first position/orientation of the surface is assessed. The image processor may generate, during use, the first stereo three-dimensional image using the assessed first position/orientation of the surface with reference to the display. The image processor may generate, during use, a second stereo three-dimensional image using an assessed second position/orientation of the surface with reference to the display.

摘要： Systems and methods for calibrating a three dimensional (3D) stereoscopic display system may include rendering a virtual model on a display of a 3D stereoscopic display system that may include a substantially horizontal display. The virtual model may be geometrically similar to a physical object placed at a location on the display. A vertex of the virtual model may be adjusted in response to user input. The adjustment may be such that the vertex of the virtual model is substantially coincident with a corresponding vertex of the physical object.

摘要： Systems and methods for calibrating a three dimensional (3D) stereoscopic display system may include rendering a virtual object on a display of a 3D stereoscopic display system that may include a substantially horizontal display.

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.
