Abstract: 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.

Abstract: 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.

Abstract: A connector to interface between a head-mounted display (HMD) device and a computing device is provided. The connector includes a housing, a first port positioned within the housing to receive a first cable that is connectable to the computing device and to exchange a first plurality of signals between the computing device and the HMD device, a second port positioned within the housing to receive a second cable that is connectable to the HMD device, the second port coupled with the first port to exchange the first plurality of signals between the computing device and the HMD device, and a third port positioned within the housing to receive a third cable that is connectable to a peripheral device, the third port coupled with the first port to exchange a second plurality of signals between the computing device and the peripheral device.

Abstract: 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.

Abstract: 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.
