Display system, information presentation system, method for controlling display system, recording medium, and mobile body
A display system includes a display unit which displays a virtual image in a target space, a controller which controls display of the display unit, and an obtaining unit which obtains vibration information about vibration applied to the display unit. The controller changes the display mode of the virtual image based on the vibration information, when the vibration exceeds a first threshold value and a viewing distance of the virtual image exceeds a second threshold value.
1. A display system which projects an image to be viewed by a target person as if a virtual image is being projected onto a target space, the display system comprising:
a display unit which displays the image;
a controller which controls display of the display unit; and
a vibration information obtaining unit which obtains vibration information about vibration applied to the display unit,
wherein the controller changes a display mode of a portion of the virtual image based on the vibration information, when the vibration exceeds a first threshold value and a viewing distance of the portion of the virtual image exceeds a second threshold value.
2. The display system according to claim 1 ,
wherein the display mode is a transmittance of the portion of the virtual image.
3. The display system according to claim 1 ,
wherein the display mode is a size of the portion of the virtual image.
4. The display system according to claim 1 ,
wherein the display mode is a shape of the portion of the virtual image.
5. The display system according to claim 4 ,
wherein the controller changes the shape of the portion of the virtual image so that the viewing distance becomes less than or equal to the second threshold value.
6. The display system according to claim 1 ,
wherein the vibration is a change over time in an orientation of the display unit.
7. An information presentation system comprising:
the display system according to claim 1 ; and
a detection system which detects the vibration applied to the display unit,
wherein the vibration information obtaining unit obtains the vibration information from the detection system.
8. A mobile body comprising:
the display system according to claim 1 ; and
a reflection member which has a light transmitting property, and reflects light emitted from the display unit so that the virtual image is viewed by the target person.
9. A method for controlling a display system which projects an image to be viewed by a target person as if a virtual image is being projected onto a target space, the display system including a display unit which displays the image, a controller which controls display of the display unit, and a vibration information obtaining unit which obtains vibration information about vibration applied to the display unit, the method comprising
causing the controller to change a display mode of a portion of the virtual image based on the vibration information, when the vibration exceeds a first threshold value and a viewing distance of the portion of the image exceeds a second threshold value.
10. A non-transitory machine-readable recording medium that stores a program for causing a computer system to execute the method for controlling the display system according to claim 9 .
