Display control device, display control method, and recording medium
There is provided a display control device including a display controller configured to place a virtual object within an augmented reality space corresponding to a real space in accordance with a recognition result of a real object shown in an image captured by an imaging part, and an operation acquisition part configured to acquire a user operation. When the user operation is a first operation, the display controller causes the virtual object to move within the augmented reality space.
1. A device comprising:
circuitry configured to
determine, based on a position of a recognized real object, a position of a virtual object, and
output a signal to change the position of the virtual object in response to a user operation,
wherein, even when a position and an attitude of the device changes, the virtual object remains fixedly displayed at the determined position until the user operation.
2. The device according to claim 1 , wherein the device is a mobile phone.
3. The device according to claim 1 , further comprising:
a touch screen.
4. The device according to claim 1 , wherein the position of the virtual object determined based on the position of the recognized real object is an initial position for display of the virtual object.
5. The device according to claim 1 , wherein the circuitry is further configured to
determine, based on a sensor data, an attitude of the virtual object.
6. The device according to claim 5 , wherein the sensor data indicates a direction of gravity.
7. The device according to claim 1 , wherein the circuitry is further configured to
output a signal to change a size of the virtual object in response to a second user operation.
8. The device according to claim 1 , wherein the user operation comprises an operation of two fingers.
9. The device according to claim 1 , wherein the user operation comprises an operation of holding the virtual object by two fingers.
10. The device according to claim 1 , wherein the user operation specifies the virtual object as a target of operation.
11. The device according to claim 10 , wherein the user operation comprises an operation performed by two fingers.
12. The device according to claim 1 , wherein the user operation comprises a drag operation.
13. The device according to claim 1 , wherein the device further comprises:
a transmissive head mounted display.
14. The device according to claim 1 , wherein the circuitry is further configured to
recognize an environment of a real space based on image data of the real space within which the recognized real object is located, and
determine a position of the device based on the recognized environment.
15. The device according to claim 14 , wherein the circuitry is further configured to
determine an attitude of the device based on the recognized environment.
16. The device according to claim 14 , further comprising:
a camera configured to obtain the image data of the real space.
17. The device according to claim 1 , further comprising:
a 3-axis acceleration sensor.
18. A method comprising:
determining, based on a position of a recognized real object, a position of a virtual object; and
outputting a signal to change the position of the virtual object in response to a user operation,
wherein, even when a position and an attitude of the device changes, the virtual object remains fixedly displayed at the determined position until the user operation.
19. A non-transitory computer-readable recording medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
determining, based on a position of a recognized real object, a position of a virtual object; and
outputting a signal to change the position of the virtual object in response to a user operation,
wherein, even when a position and an attitude of the device changes, the virtual object remains fixedly displayed at the determined position until the user operation.
