A display apparatus includes a first pixel and a second pixel. Each of the first and second pixels includes a first sub-pixel which emits light having a first color, a second sub-pixel which emits light having a second color different from the first color, a third sub-pixel which emits light having a third color different from the first and second colors, and an infrared sub-pixel which emits infrared light. The infrared light emitted from the infrared sub-pixel in the first pixel and the infrared light emitted from the infrared sub-pixel in the second pixel have different intensities from each other.

A digital image display device for displaying a sequence of digital media assets, the digital media assets including both individual digital still images and groups of related digital still images, comprising a display screen; a processor; and a processor-accessible program memory. The processor-accessible program memory stores executable instructions for causing the processor to execute the steps of: designating a sequence of digital media assets; and sequentially displaying each digital media asset in the sequence of digital media assets on the display screen, wherein if a displayed digital media asset is an individual digital still image it is displayed for a specified display time duration, and if a displayed digital media asset is a group of related digital still images the display time duration is subdivided and each of the digital still images in the group of related digital still images is displayed for a corresponding display time duration fraction.

Disclosed are systems, methods, and non-transitory computer readable media for making virtual colored markings on objects. Instructions may include receiving an indication of an object; receiving from an image sensor an image of a hand of an individual holding a physical marking implement; detecting in the image a color associated with the marking implement; receiving from the image sensor image data indicative of movement of a tip of the marking implement and locations of the tip; determining from the image data when the locations of the tip correspond to locations on the object; and generating, in the detected color, virtual markings on the object at the corresponding locations.

Aspects of the present disclosure are directed to creating and administering artificial reality collaborative working environments and providing interaction modes for them. An XR work system can provide and control such artificial reality collaborative working environments to enable, for example, A) links between real-world surfaces and XR surfaces; B) links between multiple real-world areas to XR areas with dedicated functionality; C) maintaining access, while inside the artificial reality working environment, to real-world work tools such as the user's computer screen and keyboard; D) various hand and controller modes for different interaction and collaboration modalities; E) use-based, multi-desk collaborative room configurations; and F) context-based auto population of users and content items into the artificial reality working environment.

Provided herein are method, apparatus, and computer program products for generating a first and second three dimensional interactive environment. The first three dimensional interactive environment may contain one or more engageable virtual interfaces that correspond to one or more items. Upon engagement with a virtual interface the second three dimensional interactive environment is produced to virtual simulation related to the one or more items.

In a head mounted display 100, a memory 71 stores an application. An image pickup unit 74 takes an image of a site of a user 1, and a position specifying unit 73 specifies a position and a direction of the head mounted display 100. A detector 75 detects a position indicated by the user 1 on the basis of the image taken by the image pickup unit 74, and a setting unit 76 sets a position indicating a home position on the basis of a result detected by the detector 75 and the position and the direction specified by the position specifying unit 73.

The present invention discloses systems and methods for both viewing and interacting with a virtual reality (VR), an augmented reality (AR) or a mixed reality (MR). More specifically, the systems and methods allow the user to interact with aspects of such realities including virtual items presented in such realities or within such environments by manipulating a control device that has an inside-out camera mounted on-board. The apparatus or system uses two distinct representations including a reduced representation in determining the pose of the control device and uses these representations to compute an interactive pose portion of the control device to be used for interacting with the virtual item. The reduced representation is consonant with a constrained motion of the control device.

An apparatus is disclosed for bidirectional amplification with phase-shifting. In example implementations, an apparatus includes a phase shifter with a bidirectional amplifier. The bidirectional amplifier includes a first transistor coupled between a first plus node and a second minus node, a second transistor coupled between a first minus node and a second plus node, a third transistor coupled between the first plus node and the second minus node, and a fourth transistor coupled between the first minus node and the second plus node. The bidirectional amplifier also includes a fifth transistor coupled between the first plus node and the second plus node, a sixth transistor coupled between the first minus node and the second minus node, a seventh transistor coupled between the first plus node and the second plus node, and an eighth transistor coupled between the first minus node and the second minus node.
