Abstract: The subject disclosure is directed towards a hybrid stereo image/motion parallax system that uses stereo 3D vision technology for presenting different images to each eye of a viewer, in combination with motion parallax technology to adjust each image for the positions of a viewer's eyes. In this way, the viewer receives both stereo cues and parallax cues as the viewer moves while viewing a 3D scene, which tends to result in greater visual comfort/less fatigue to the viewer. Also described is the use of goggles for tracking viewer position, including training a computer vision algorithm to recognize goggles instead of only heads/eyes.

Abstract: The present technology relates to a display control apparatus, a display control method, and a program which can implement a UI that allows a user to intuitively select an intended region in an image. A position of a display surface on which a display apparatus displays an image is detected, and a projected image obtained by projecting an image model of a predetermined image is displayed on the display surface along a straight light passing through a position of the user and a pixel of the display surface whose position is detected. The present technology can be applied to apparatuses having an image displaying function, such as a smartphone and a tablet terminal.

Abstract: A method and system for displaying a 2D representation of a 3D world on an image plane of a simulator. The image plane defines a fixed viewing region of the replica environment of the simulator and also corresponds to a view observed by an operator of the simulator. The method includes the steps of determining a head position of the operator of the replica environment and modifying a viewing volume of the 3D world based on the head position of the operator while keeping the image plane constant to form a modified viewing volume. The 2D representation based on the modified viewing volume is then generated and displayed on the image plane.

Abstract: An eye-point detection unit (26) tracks the eye-points of a user after detecting the user who views a three-dimensional image including left-eye and right-eye parallax images obtained when a subject is viewed by the user from a given position established as a view reference position. When the movement speed of the eye-points becomes equal to or greater than a predetermined magnitude, a dynamic parallax correction unit (30) determines, on the basis of the movement amounts of the eye-points, dynamic parallax correction amounts for the respective left-eye and right-eye parallax images, thereby generating and outputting a three-dimensional image as dynamic parallax corrected to a display unit (36). When the movement speed of the eye-points becomes less than the predetermined magnitude, the dynamic parallax correction unit (30) stepwise reduces the correction amount of the dynamic parallax correction until the left-eye and right-eye parallax images return to the respective parallax images obtained when the subject is viewed from the view reference position, thereby generating and outputting a three-dimensional image to the display unit (36).
