Abstract
An information processing device of the present invention includes a sightline distance calculating unit (106) configured to calculate a sightline distance between a position of a user and a position of a point specified on an image display surface based on a sightline direction of the user, a character size calculating unit (108) configured to determine a character size in accordance with the sightline distance calculated by the sightline distance calculating unit (106), and a display control unit (110) configured to determine a size of a display image in accordance with the character size calculated by the character size calculating unit (108).
Claims18
An information processing device, comprising:
- a central processing unit (CPU) configured to:
- control an image display surface to display a display image;
- determine a user sightline direction based on a user image;
- calculate a user viewing position on the image display surface based on the determined user sightline direction;
- calculate a sightline distance between a user eye position in front of the image display surface and the user viewing position on the image display surface, based on the determined user sightline direction;
- calculate a size of a character included in the display image based on a user viewing angle and the calculated sightline distance;
- set the size of the character as a first size based on the calculated size of the character that is smaller than the first size;
- and
- determine a size of the display image displayed on the image display surface, wherein the size of the display image is determined based on the calculated sightline distance and the calculated size of the character.
An information processing method, comprising:
- controlling an image display surface to display a display image;
- determining a user sightline direction based on a user image;
- calculating a user viewing position on the image display surface based on the determined user sightline direction;
- calculating a sightline distance between a user eye position in front of the image display surface and the user viewing position on the image display surface, based on the determined user sightline direction;
- calculating a size of a character included in the display image based on a user viewing angle and the calculated sightline distance;
- setting the size of the character as a first size based on the calculated size of the character that is smaller than the first size;
- and
- determining a size of the display image displayed on the image display surface, wherein the size of the display image is determined based on the calculated sightline distance and the calculated size of the character.
A non-transitory computer-readable medium having stored thereon computer-readable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- controlling an image display surface to display a display image;
- determining a user sightline direction based on a user image;
- calculating a user viewing position on the image display surface based on the determined user sightline direction;
- calculating a sightline distance between a user eye position in front of the image display surface and the user viewing position on the image display surface, based on the determined user sightline direction;
- calculating a size of a character included in the display image based on a user viewing angle and the calculated sightline distance;
- setting the size of the character as a first size based on the calculated size of the character that is smaller than the first size;
- and
- determining a size of the display image displayed on the image display surface, wherein the size of the display image is determined based on the calculated sightline distance and the calculated size of the character.
