In an example in accordance with the present disclosure, a system is described. The system includes a display device and a gaze tracking system to capture eye movements of a user looking at the display device. The system also includes a controller. The controller authenticates the user based on eye movements of the user matching an eye movement authentication pattern. The controller also calibrates a computing device based on the eye movements of the user.

Authentication and calibration via gaze tracking

In an example implementation, a head-mounted display (HMD) device includes a display, a variable lens receptacle to receive an interchangeable lens, a sensor to retrieve lens information from the lens, and a controller to obtain images that are predistorted according to the lens information, wherein the controller is to display the predistorted images on the display.

Head-mounted displays

Computer-implemented methods, systems, apparatus, and computer-readable media (transitory or non-transitory) are described herein for detecting eye tracking calibration errors. In various examples, respective poses of first and second eyes of a wearer of a head-mounted display ('HMD') may be determined. A portion of a first image rendered on a first display of the HMD may be selected based on the pose of the first eye of the wearer. The selected portion of the first image may be matched to a portion of a second image rendered on a second display of the HMD. An eye tracking calibration error may be determined based on the pose of the second eye of the wearer and a location of the portion of the second image.

Detecting eye tracking calibration errors

In example implementations, a server is provided. The server incudes a communication interface, a memory, and a processor communicatively coupled to the communication interface and the memory. The communication interface is to establish a communication session with virtual reality (VR) system to receive room identification information. The memory is to store a plurality of VR boundary maps for a plurality of different rooms. The processor is to compare the room identification information to the plurality of different rooms stored in the memory to identify a room of the plurality of different rooms, identify a VR boundary map from the plurality of VR boundary maps associated with the room, and transmit the VR boundary map to the VR system via the communication session.

Boundary maps for virtual reality systems

A sleeve for receiving a computing device includes airflow channels. One example sleeve may include a discrete GPU to be connected to the computing device and output signals to a display device.

VR/AR sleeves

In some examples, a processor of a system is to cause display of a virtual input device on a display device, the virtual input device corresponding to a pressure sensitive surface, and perform different tasks responsive to different touch pressures applied on a first location of the pressure sensitive surface.

Virtual input devices for pressure sensitive surfaces

A display system includes a head-mountable 3D display device including at least one sensor to sense an absolute position and orientation of the 3D display device. The display system includes an accessory wearable by a user. The accessory includes at least one sensor to sense a relative position and orientation of the 3D display device relative to the accessory. An absolute position and orientation of a torso of the user may be determined based on the sensed absolute position and orientation of the 3D display device and the sensed relative position and orientation of the 3D display device relative to the accessory.

Determining position and orientation of a user's torso for a display system

A method of deriving data of a user's body pose in an enhanced reality system includes, with at least one camera coupled to a body-mounted housing, capturing at least one image in three-dimensional (3D) space of at least one extremity of a body of a user on which the body-mounted housing is mounted, and with a processor executing a body pose module, deriving data of a user's body pose based on the at least one image captured by the camera.

Enhanced reality systems

In some examples, a system is to receive an input from an input device that senses a portion of a pattern on a three-dimensional (3D) object formed by 3D printing, map the sensed portion of the pattern onto a 3D location on the 3D object, and produce an output corresponding to the 3D location on the 3D object in response to the input.

Patterns for locations on three-dimensional objects

An enhanced reality system includes, in an example, a processor, an enhanced reality display to present, via execution of the processor, a view of an enhanced reality environment to a first user, a display device to present to at least a second user, via execution of the processor, a stabilized tracked view of the enhanced reality environment presented to the first user wherein the view of the enhanced environment provided by the display device is provided using a camera.

Stabilized and tracked enhanced reality images

An input system for a 3D display device includes a pen, and a tablet computing device to receive input via interaction with the pen. The tablet computing device including a display dock to dock the 3D display device and a pen dock to dock the pen, wherein docking of the 3D display device in the display dock facilitates a determination of a display position of a visual representation of the tablet computing device on the 3D display device.

Tablet computing device with display dock

In example implementations, a method executed by a processor is provided. The method receives a first pen input from first pen and a second pen input from a second pen. The first pen and the second pen interact with a single display. The first pen input and the second pen input are translated into a first output and a second output, respectively, that are executed by an application. The first output and the second output are sent to the application. The application executes the first output and the second output simultaneously.
