Abstract

A display position of an image is moved in accordance with positional information of a display device having a curved display surface. Displacement of a display device is sensed by a camera portion and an acceleration sensor, and the display position is determined in accordance with the displacement, so that the image is displayed in the display position. In the case where the display device rotates and the like, a desired piece of information can be displayed automatically in a display region that can be easily seen.

First claim

What is claimed is:

1. A display device comprising:
a sensing unit configured to sense positional information of the display device; and
a display portion configured to display an information on a display surface and an image in a display position on the display surface at the same time, the display position being determined in accordance with the positional information,
wherein the display device has a curved shape,
wherein the positional information comprises rotational positional information based on rotation in a circumferential direction of the display device, and
wherein the display position is configured to move, in a direction opposite to the circumferential direction, a length of rθ (product of r and θ) where r is a radius of the display device and θ radian is an angle of rotation in the circumferential direction of the display device.

2. The display device according to claim 1 , wherein the sensing unit comprises an acceleration sensor.

3. The display device according to claim 1 , wherein the display position is configured to move in a direction opposite to the rotation in the circumferential direction.

4. The display device according to claim 1 , wherein the display surface of the display portion exists in a range of larger than 180° and smaller than or equal to 360° along a circumferential direction of the display device.

5. The display device according to claim 1 , wherein the display device is a wearable display device.

6. A driving method of a display device, comprising:
sensing displacement of a curved-shaped display device;
determining a display position in accordance with the displacement; and
displaying an information on a display surface and an image in the display position on the display surface at the same time,
wherein the displacement comprises rotational displacement based on rotation in a circumferential direction of the display device, and
wherein the display position is configured to move, in a direction opposite to the circumferential direction, a length of rθ (product of r and θ) where r is a radius of the display device and θ radian is an angle of rotation in the circumferential direction of the display device.

7. The driving method of a display device according to claim 6 , wherein the displacement is sensed by an acceleration sensor.

8. The driving method of a display device according to claim 6 , wherein the display position is configured to move in a direction opposite to the rotation in the circumferential direction.

9. The driving method of a display device according to claim 6 , wherein the display surface configured to display the image exists in a range of larger than 180° and smaller than or equal to 360° along a circumferential direction of the display device.

10. A non-transitory computer-readable memory medium storing a program,
wherein the program comprises:
an instruction to sense displacement of a display device;
an instruction to move a display position of an image in accordance with the displacement; and
an instruction to display an information on a display surface and the image in the display position on the display surface at the same time,
wherein the displacement comprises rotational displacement based on rotation in a circumferential direction of the display device, and
wherein the display position is configured to move, in a direction opposite to the circumferential direction, a length of rθ (product of r and θ) where r is a radius of the display device and θ radian is an angle of rotation in the circumferential direction of the display device.

11. The non-transitory computer-readable memory medium according to claim 10 , wherein the displacement is sensed by an acceleration sensor.

12. The non-transitory computer-readable memory medium according to claim 10 , wherein the display position is configured to move in a direction opposite to the rotation in the circumferential direction.

13. The non-transitory computer-readable memory medium according to claim 10 , wherein the display surface configured to display the image exists in a range of larger than 180° and smaller than or equal to 360° along a circumferential direction of the display device.

14. The display device according to claim 1 , further comprising:
a second sensing unit comprising an acceleration sensor, wherein the sensing unit comprises an acceleration sensor.

15. The driving method of a display device according to claim 6 , wherein the displacement is sensed by a first acceleration sensor and a second acceleration sensor.

16. The non-transitory computer-readable memory medium according to claim 10 , wherein the displacement is sensed by a first acceleration sensor and a second acceleration sensor.

17. The display device according to claim 1 , wherein the curved shape is a ring shape.

18. The driving method of a display device according to claim 6 , wherein the curved-shaped display device is a ring-shaped display device.
