Abstract

A projector detects a first input operation and a second input operation using an operation detection section, detects an operation position of the input operation in an operation area in which the input operation can be detected, and notifies the first operation and the operation position when the second operation is not detected within a predetermined time from when the first input operation is detected.

Claims

1. An input device comprising:

an operation detection section which detects an input operation;

a position detection section which detects an operation position of the input operation in an operation area in which the input operation can be detected by the operation detection section; and

an operation notification section which notifies a first operation and the operation position detected by the position detection section, when a second input operation is not detected within a predetermined time after a first input operation is detected by the operation detection section.

2. The input device according to claim 1,

wherein after the first operation and an operation position detected by the position detection section are notified, the operation notification section notifies a release of the first operation.

3. The input device according to claim 2,

wherein after the first operation and an operation position detected by the position detection section are notified, the operation notification section notifies a release of the first operation before a second input operation is detected by the operation detection section.

4. The input device according to claim 3,

wherein the operation notification section notifies the release of the first operation after a predetermined time elapses after the first operation and an operation position detected by the position detection section are notified.

5. The input device according to claim 3,

wherein the operation notification section performs other process without being accompanied by notification between a time when the first operation and the operation position detected by the position detection section are notified and a time when the second input operation is detected by the operation detection section.

6. The input device according to claim 2,

wherein after the second input operation is detected by the operation detection section, the operation notification section notifies the release of the first operation.

7. The input device according to any one of claim 1,

wherein the operation notification section notifies a second operation different from the first operation, when a second input operation is detected within a predetermined time after the first input operation is detected by the operation detection section.

8. The input device according to claim 7,

wherein after the second operation is notified, the operation notification section notifies the release of the second operation.

9. The input device according to claim 7,

wherein the operation notification section notifies the second operation and the operation position detected by the position detection section.

10. The input device according to any one of claim 1,

wherein the input device is configured as a projector,

the projector including:

a light modulation section which modulates a light emitted from a light source;

an image forming section which forms a display image in the light modulation section based on image data; and

a projection section which projects a display image formed by the image forming section,

wherein a range that the display image projected by the projection section displays is an operation area.

11. A display system in which a projector detects an input operation that is input by an indicating body and notifies a computer of an operation in response to the input operation, and the computer executes the operation,

wherein the indicating body includes an operator and transmitting section which indicates an input operation that is input by the operator to the projector,

wherein the projector includes

a light modulation section which modulates a light emitted from the light source;

an image forming section which forms a display image in the light modulation section based on image data;

a projecting section which projects a display image formed by the image forming section;

an operation detection section which detects an input operation that is notified by the indicating body;

a position detection section which detects an operation position of the input operation detected by the operation detection section in an operation area that the display image that is projected by the projecting section displays; and

an operation notification section which notifies the computer of a first operation and an operation position detected by the position detection section, when a second input operation is not detected within a predetermined time after a first input operation is detected by the operation detection section, and

wherein the computer includes control section which executes the first operation, based on the notification from the operation notification section.

12. The display system according to claim 11,

wherein the operation notification section notifies the computer of a second operation different from the first operation, when a second input operation is detected within a predetermined time after the first input operation is detected by the operation detection section, and

wherein the control section executes the second operation, based on the notification from the operation notification section.

13. The display system according to claim 12,

wherein the computer includes a pointing device having operators of two or more, and

wherein the operation notification section notifies the computer of the first operation as an operation by the first operator included in the pointing device, and notifies the computer of the second operation as an operation by the second operator included in the pointing device.

14. An input method comprising:

detecting a first input operation and a second input operation;

detecting an operation position of the input operation in an operation area in which the input operation can be detected; and

notifying a first operation and an operation position, when a second input operation is not detected within a predetermined time after a first input operation is detected.
