Abstract: A display system including: display apparatus; display-apparatus-tracking means; input device; processor. The processor is configured to: detect input event and identify actionable area of input device; process display-apparatus-tracking data to determine pose of display apparatus in global coordinate space; process first image to identify input device and determine relative pose thereof with respect to display apparatus; determine pose of input device and actionable area in global coordinate space; process second image to identify user's hand and determine relative pose thereof with respect to display apparatus; determine pose of hand in global coordinate space; adjust poses of input device and actionable area and pose of hand such that adjusted poses align with each other; process first image, to generate extended-reality image in which virtual representation of hand is superimposed over virtual representation of actionable area; and render extended-reality image.

Abstract: A gaze-tracking system for use in head-mounted display apparatus. The gaze-tracking system includes: illuminators; camera; and processor configured to: illuminate illuminators in sequential manner; control camera to capture eye images of user's eye during illumination of illuminators; identify reflection(s) of illuminator in eye image; determine extent of deformation in shape of reflection(s) with respect to shape of illuminator; determine extent of displacement in position of reflection(s) with respect to position of illuminator; compute user-specific score for illuminator based on extents of deformation and displacement; select illuminator(s) based on user-specific scores; illuminate illuminator(s); control camera to capture eye image of user's eye during illumination of illuminator(s); and detect gaze direction of user based upon relative position of pupil of user's eye with respect to reflections of illuminator(s) in eye image.

Abstract: An imaging system and a method for producing extended-reality images for a display apparatus. The imaging system includes camera and processor. The processor is configured to: control camera to capture image of real-world environment; analyse captured image to identify first image segment representing input device and to determine location of at least one actionable area of input device in first image segment; determine at least one functional element to be presented for the actionable area, the functional element being indicative of at least one of: functionality of the at least one actionable area, status of the at least one actionable area; and process captured image to generate extended-reality image in which the functional element is virtually superimposed over the actionable area of input device or a virtual representation of the actionable area of input device.
