  • Patent number: 10366536
    Abstract: In various embodiments, computerized methods and systems for rendering near-field objects as perceivable far-field objects within a virtual environment are provided. A determination is made that a near-field object to be rendered is configured for far-field perception within the virtual environment. The virtual environment is operable to include one or more virtualized near-field objects that are stereoscopically rendered utilizing one or more stereoscopic projection transforms generated based at least in part on a position and orientation of a head-mounted display. A harmonize transform is generated for the configured near-field object based at least in part on one of the stereoscopic projection transforms. Based on the determination that the near-field object is configured for far-field perception, the generated harmonize transform is employed to stereoscopically render the configured near-field object as a perceivable far-field object within the virtual environment.

  • Patent number: 9728012
    Abstract: An object-image alignment data generating method for use in an object recognition system is presented. The method obtains a 3D model and a set of 2D images of the object. Each 2D image from the set is captured based on a particular camera point of view. The method then uses the 3D model of the object to generate multiple silhouettes of the object according to different camera point of views. Each silhouette is then matched and aligned with a 2D image based on the corresponding camera point of view. The method also derives at least one descriptor from the 2D images and compiles feature points that correspond to the descriptors. Each feature point includes a 2D location and a 3D location. The method then generates an object-image alignment packet by packaging the 2D images, the descriptors, and the feature points.

  • Patent number: 9367951
    Abstract: Graphical elements displayed on a two-dimensional display screen have an appearance that is consistent with a three-dimensional view of those elements over a range of viewing angles. A current viewing angle of a user is determined, and a view of an element to be rendered can be determined that includes an orientation appropriate for the current viewing angle. An image manipulation process is applied in order to enable the element to have the determined view from the current viewing angle of the user, taking into account the angle of the display screen with respect to the user. In at least some embodiments, an anamorphic skewing process can be used to correlate locations on the display screen with apparent positions of those locations at the current viewing angle, and cause the graphical elements to be rendered on the display screen with a skew or distortion based on the correlated locations.

  • Patent number: 9230368
    Abstract: A system and method are disclosed for displaying virtual objects in a mixed reality environment in a way that is optimal and most comfortable for a user to interact with the virtual objects. When a user is moving through the mixed reality environment, the virtual objects may remain world-locked, so that the user can move around and explore the virtual objects from different perspectives. When the user is motionless in the mixed reality environment, the virtual objects may rotate to face the user so that the user can easily view and interact with the virtual objects.

  • Patent number: 9122321
    Abstract: A see-through, near-eye, mixed reality display device and system for collaboration amongst various users of other such devices and personal audio/visual devices of more limited capabilities. One or more wearers of a see through head mounted display apparatus define a collaboration environment. For the collaboration environment, a selection of collaboration data and the scope of the environment are determined. Virtual representations of the collaboration data in the field of view of the wearer, and other device users are rendered. Persons in the wearer's field of view to be included in collaboration environment and who are entitled to share information in the collaboration environment are defined by the wearer. If allowed, input from other users in the collaboration environment on the virtual object may be received and allowed to manipulate a change in the virtual object.

  • Patent number: 9041807
    Abstract: An image processing device configured to be installed in a vehicle includes an image acquirer, an image selector, a first luminance adjuster, a synthetic image generator, and an image provider. The image acquirer acquires camera images captured by cameras provided on the vehicle. The image selector selects one of the camera images as a representative image based on luminances of the camera images. The first luminance adjuster adjusts a luminance of at least one of the other camera images based on a luminance of the representative image. The synthetic image generator generates a synthetic image showing a periphery of the vehicle, based on the representative image and the other camera images the luminance of at least one of which has been adjusted by the first adjuster. The image provider outputs, to a display device installed in the vehicle, information corresponding to the synthetic image.

    Abstract: In a stereoscopic video observation device 200, an optically transmissive HMD 208 presents video observed when a three-dimensional image in a virtual three-dimensional space is projected into a real space. A transmittance changing section changes the transmittance of light that passes through the optically transmissive HMD 208. A shutter control section 220 sets a lower limit value of the light transmittance that can be changed by the transmittance changing section.
