Image display system, image control method, and image control program
An image display system includes a floating image display unit that displays a floating image as a real image in a predetermined displayable region in a three-dimensional space, a sensor unit that detects a user in the vicinity of the displayable region and outputs detection information, and a control unit that identifies a gesture, including at least one of body part movement and posture of the user, based on the detection information, and when the gesture is a predetermined position designation gesture designating a display position of the floating image in the displayable region, controls the floating image display unit so that the floating image is displayed at a designated display position as the display position designated by the position designation gesture.
1 . An image display system comprising:
a floating image display that displays a floating image as a real image in a predetermined displayable region in a three-dimensional space;
a sensor including a camera that detects a user in a vicinity of the displayable region, outputs detection information based on the detected user, photographs a subject and outputs image data of the subject; and
control circuitry that:
identifies a three-dimensional position of eyes or a face of the user based on the detection information,
identifies a gesture of the user, including the user pointing at the subject which is desired to be displayed as the floating image,
identifies the floating image based on the output image data and the gesture of the user, and
in response to the gesture of the user, controls the floating display to display an image of the subject as the floating image based on the image data, the floating image being displayed at a display position that is based on the three-dimensional position of the eyes or the face of the user.
2 . The image display system according to claim 1 , wherein the control circuitry changes the display position of the floating image based on a position and a line of sight of the eyes of the user.
3 . The image display system according to claim 1 , wherein the control circuitry detects a state of a skeletal structure of the user based on the detection information and determines the display position further based on the state of the skeletal structure.
4 . The image display system according to claim 1 , wherein
the floating image display includes a first display that displays a first image, a second display that displays a second image, and a real image optical system that displays the first image or the second image as the floating image as the real image,
a distance from the first display to the real image optical system is longer than a distance from the second display to the real image optical system, and
the control circuitry identifies a second gesture, including at least one of the body part movement and the posture of the user, based on the detection information, and when the second gesture is a predetermined depth designation gesture designating a depth direction position of the displayable region, controls the floating image display so that the floating image is displayed in the displayable region whose depth direction position is designated by the depth designation gesture.
5 . The image display system according to claim 1 , wherein the control circuitry identifies a second gesture that is a predetermined size designation gesture for enlarging/reducing size of the floating image in the displayable region, and
the control circuitry controls the floating image display so that the floating image is displayed in the size designated by the size designation gesture.
