Information processing apparatus, information processing method, program, and head-mounted display
There is provided an information processing apparatus capable of displaying an image properly even if an orientation of a display device is rapidly changed, an information processing method, a program, and a head-mounted display. An information processing apparatus for controlling a display section configured to be capable of displaying an image in a displayable area preset in a space by a sequential scanning method includes a setting section and a determination section. The setting section sets the displayable area so as to remain at a certain position in the space. The determination section acquires information about a posture of the display section, calculates a moving direction of the displayable area as viewed from the display section along with a change in the posture of the display section, and determines a main scanning direction of the display section in a direction opposite to the moving direction.
1. An information processing apparatus for controlling a display section configured to display an image in a displayable area preset in a space by a sequential scanning method, comprising:
a setting section configured to set the displayable area so as to remain at a certain position in the space; and
a determination section configured to
acquire information about a posture of the display section,
calculate a moving direction of the displayable area as viewed from the display section along with a change in the posture of the display section, and
determine a main scanning direction of the sequential scanning method of the display section in a direction opposite to the moving direction,
wherein the setting section and the determination section are each implemented via at least one processor.
2. The information processing apparatus according to claim 1 , further comprising:
a detection section configured to detect the change in the posture of the display section,
wherein the determination section acquires the information about the change in the posture of the display section detected by the detection section, and
wherein the detection section is implemented via at least one processor.
3. The information processing apparatus according to claim 2 , wherein
the detection section includes an inertial measurement unit provided in the display section.
4. An information processing method of controlling a display section configured to display an image in a displayable area preset in a space by a sequential scanning method, comprising:
setting the displayable area so as to remain at a certain position in the space;
acquiring information about a posture of the display section;
calculating a moving direction of the displayable area as viewed from the display section along with a change in the posture of the display section; and
determining a main scanning direction of the sequential scanning method of the display section in a direction opposite to the moving direction.
5. A non-transitory computer-readable storage medium having embodied thereon a program, which when executed by a computer of an information processing apparatus causes the information processing apparatus to execute a method for controlling a display section configured to display images in a displayable area preset in a space by a sequential scanning method, the method for controlling the display section comprising:
setting the displayable area so as to remain at a certain position in the space;
acquiring information about a posture of the display section;
calculating a moving direction of the displayable area as viewed from the display section along with a change in the posture of the display section; and
determining a main scanning direction of the sequential scanning method of the display section in a direction opposite to the moving direction.
6. A head-mounted display, comprising:
a frame configured to be worn on a head of a user;
a display section provided in the frame and configured to display an image in a displayable area preset in a space by a sequential scanning method; and
a control section including
a setting section for setting the displayable area so as to remain at a certain position in the space, and
a determination section for acquiring information about a posture of the display section, calculating a moving direction of the displayable area as viewed from the display section along with a change in the posture of the display section, and determining a main scanning direction of the sequential scanning method of the display section in a direction opposite to the moving direction;
wherein the control section is implemented via at least one processor.
