Abstract
A head mounted display includes a display unit capable of transparently displaying an outside world. The head mounted display includes a processing unit that displays a moving image on the display unit; and an external sensor that detects movement in the outside world which can be transparently displayed by the display unit. The processing unit acquires the movement in the outside world obtained by the external sensor, synthesizes the acquired movement in the outside world and the moving image to be displayed, and evaluates a biological effect based on the synthesized moving image obtained by the synthesis.
Claims11
A head mounted display comprising:
- a display unit configured to (a) transparently display an outside world and permit a user to view the outside world therethrough, and (b) display a moving image;
- a processor configured to display the moving image on the display unit;
- and
- an external sensor configured to detect movement in the outside world as viewed by the user through the display unit,
- wherein the processor is configured to acquire an image of the movement in the outside world obtained by the external sensor, superimposedly synthesize the acquired image of the movement in the outside world and the moving image to be displayed, and evaluate a biological effect of displaying the moving image on the display unit based on the synthesized moving image obtained by the synthesis,
- wherein the external sensor is a camera that images the outside world that can be transparently displayed by the display unit,
- wherein the processor is configured to acquire a captured image obtained by the camera, and to acquire the synthesized moving image by synthesizing the acquired captured image and the moving image to be displayed, and
- wherein the processor is configured to calibrate the acquired captured image based on camera characteristics of the camera, and to perform the synthesis using the captured image after the calibration.
A control method of a head mounted display including a display unit configured to transparently display an outside world, to permit a user to view the outside world through the display unit, and to display a moving image, the control method comprising:
- displaying the moving image on the display unit;
- and
- detecting movement in the outside world as viewed by the user through the display unit using an external sensor,
- wherein in the displaying of the moving image,
- an image of the movement in the outside world obtained by the detecting of the movement in the outside world is acquired,
- the acquired image of the movement in the outside world and the moving image to be displayed are superimposedly synthesized, and
- a biological effect of displaying the moving image on the display unit is evaluated based on the synthesized moving image obtained by the synthesis,
- wherein the external sensor is a camera that images the outside world that can be transparently displayed by the display unit,
- wherein the method includes acquiring a captured image obtained by the camera, and acquiring the synthesized moving image by synthesizing the acquired captured image and the moving image to be displayed, and
- wherein the method further includes calibrating the acquired captured image based on camera characteristics of the camera, and performing the synthesis using the captured image after the calibration.
