Abstract

An image display device includes an acquisition unit that acquires two or more types of information, a detection unit that detects at least one of an acceleration, an orientation, and an angular velocity of the image display device, an image change section that determines a state of the image display device on the basis of a detection result of the detection unit, switches information, which is to be selected from the two or more types of information acquired by the acquisition unit, in accordance with the determined state of the image display device, and generates display data based on the switched information, and a display unit that displays the display data.

Claims

1. An image display device comprising:

an acquisition unit configured to acquire two or more types of information;

a detection unit configured to detect at least one of an acceleration, an orientation, or an angular velocity of the image display device;

a storage section configured to store information comprising,

for each state of defined states of the image display device, a first threshold value of an orientation and a first predetermined time for detecting the state of the image display device and,

for each operation of defined operations of the image display device, a second threshold value of an orientation and a second predetermined time for detecting the operation of the image display device;

an image change section configured to

determine a state of the image display device based on a detection result of the detection unit and the information stored by the storage section,

switch from first information of the two or more types of information acquired by the acquisition unit to second information of the two or more types of information in accordance with the state of the image display device, and

generate display data based on the second information; and

a display unit configured to display the display data,

wherein the image change section determines whether the image display device performs a reciprocal operation between a reference posture and an out-of-reference posture in the second predetermined time based on the detection result of the detection unit and the information stored by the storage section and generates additional information in response to determining that the image display device performs the reciprocal operation between the reference posture and the out-of-reference posture in the second predetermined time.

2. The image display device according to claim 1, wherein, based on the detection result of the detection unit, the image change section determines the state of the image display device regarding at least one of up and down, right and left, or oblique directions with respect to the reference posture of the image display device.

3. The image display device according to claim 1, wherein the additional information is information corresponding to a situation in which the image display device is used.

4. The image display device according to claim 3, wherein, in response to determining that a user of the image display device is boarding a vehicle, the acquisition unit acquires information on the vehicle from the vehicle, and the additional information is the information on the vehicle.

5. The image display device according to claim 1, wherein,

in response to a determination that a user of the image display device is boarding a vehicle, the acquisition unit acquires information on the vehicle from the vehicle, and

the additional information is the information on the vehicle.

6. An image display method of an image including a storage section configured to store information defining, for each state of defined states of the image display device, a first threshold value of an orientation and a first predetermined time for detecting the state and, for each operation of defined operations of the image display device, a second threshold value of an orientation and a second predetermined time for detecting the operation, the method comprising:

acquiring two or more types of information;

detecting at least one of an acceleration, an orientation, or an angular velocity of the image display device;

determining a state of the image display device based on a detection result of the detecting and the information stored by the storage section;

switching from first information of the two or more types of information to second information of the two or more types of information in accordance with the state of the image display device;

generating display data based on the switching;

displaying the display data;

determining whether the image display device performs a reciprocal operation between a reference posture and an out-of-reference posture in the second predetermined time based on the detection result and the information stored by the storage section; and

generating additional information in response to determining that the image display device performs the reciprocal operation between the reference posture and the out-of-reference posture in the second predetermined time.
