Abstract

The present application discloses an input device including a sensor configured to track movement of a body part of an operator and generate movement data about the movement of the body part, a processor including an operation command generator configured to generate an operation command from the movement data, a speed data generator configured to generate speed data representing a speed of the movement from the movement data, and a feedback determination portion configured to determine whether a feedback operation to allow the operator to confirm the operation command is required based on the speed data, and an operation portion including a feedback operation device configured to execute the feedback operation if the feedback determination portion determines that the feedback operation is required.

Claims

1. An input device, comprising:

a sensor configured to track movement of a body part of an operator and generate movement data about the movement of the body part,

a processor including an operation command generator configured to generate an operation command from the movement data, a speed data generator configured to generate speed data representing a speed of the movement from the movement data, and a feedback determination portion configured to determine whether a feedback operation to allow the operator to confirm the operation command is required based on the speed data, and

an operation portion including a feedback operation device configured to execute the feedback operation if the feedback determination portion determines that the feedback operation is required.

2. The input device according to claim 1, wherein

the sensor generates image data of the movement as the movement data,

the processor includes a recognition portion configured to recognize and extract gesture data from the image data,

the gesture data is used for generation of the operation command and the speed data.

3. The input device according to claim 1, wherein

the sensor includes a touch-sensitive device configured to generate the movement data in response to the body part touching the touch-sensitive device,

the processor includes a recognition portion configured to recognize and extract gesture data from the movement data, and

the gesture data is used for generation of the operation command and the speed data.

4. The input device according to claim 1, wherein

the operation portion includes a command execution device configured to execute a predetermined operation in response to the operation command, and

the feedback operation device executes notification operation to give the operator operation information about the predetermined operation defined by the operation command.

5. The input device according to claim 1, wherein

the feedback determination portion compares the speed data with a threshold to determine whether the feedback operation is required,

the operation portion executes the feedback operation if the speed data shows a lower speed than the threshold, and

the operation portion executes a predetermined operation in response to the operation command without executing the feedback operation unless the speed data shows a lower speed than the threshold.

6. The input device according to claim 1, wherein

the feedback determination portion includes a feedback candidate storage configured to store feedback candidate data about the feedback operation, and

the feedback candidate data is associated with the operation command.

7. The input device according to claim 6, wherein

the feedback determination portion selects a first feedback operation from the feedback candidate data if the operation command defines a first operation, and

the feedback determination portion selects a second feedback operation, which is different from the first feedback operation, from the feedback candidate data if the operation command defines a second operation different from the first operation.

8. The input device according to claim 6, wherein

if the operation command is irrelevant to the feedback candidate data, the operation portion executes a predetermined operation in response to the operation command without executing the feedback operation.

9. The input device according to claim 1, wherein,

the operation command includes an identifier representing whether the feedback operation is required,

the operation portion executes the feedback operation if the identifier instructs that the feedback operation is required, and

the operation portion executes a predetermined operation in response to the operation command without executing the feedback operation if the identifier instructs no requirement of the feedback operation.

10. The input device according to claim 9, wherein

if the identifier instructs that the feedback operation is required, the operation command is send to the feedback determination portion, and

the feedback determination portion determines whether the feedback operation is required based on the speed data in response to reception of the operation command.

11. The input device according to claim 9, wherein

if the identifier instructs no requirement of the feedback operation, the operation command is sent to the operation portion without passing through the feedback determination portion.

12. The input device according to claim 9, wherein

the operation command generator determines whether the identifier instructs that the feedback operation is required or the identifier instructs no requirement of the feedback operation based on the movement data.

13. The input device according to claim 9, wherein

the identifier is editable.

14. The input device according to claim 2, wherein

the recognition portion extracts data representing a hand of the operator as the gesture data if the hand defines a three-dimensional coordination system.

15. The input device according to claim 1, wherein

the operation portion includes a feedback interface device configured to receive a confirmation result of the feedback operation from the operator, and

the confirmation result is confirmative for executing the operation command or cancellation of the operation command.

16. The input device according to claim 15, wherein

if the confirmation result instructs that the operation command is to be executed, the operation portion executes a predetermined operation in response to the operation command.

17. The input device according to claim 15, wherein

if the confirmation result instructs that the operation command is cancelled, the operation command generator generates an alternative operation command without receiving new movement data from the sensor.

18. The input device according to claim 17, wherein

the feedback determination portion determines that a feedback operation in response to the alternative operation command is required, and

the operation portion executes the feedback operation in response to the alternative operation command.

19. The input device according to claim 17, wherein

the speed data is used by the operation command generator to generate the alternative operation command.

20. The input device according to claim 17, wherein

the operation command generator generates the alternative operation command only 1 time after cancellation of the operation command.

21. The input device according to claim 17, wherein

the operation command generator generates the alternative operation command only 2 times after each cancellation of the operation command and a former alternative operation command.

22. A method for inputting an operational request comprising steps of:

tracking movement of a body part of an operator to generate movement data about the movement of the body part,

generating an operation command defining a predetermined operation and speed data representing a speed of the movement from the movement data,

determining whether a feedback operation to allow the operator to confirm the operation command is required based on the speed data, and

executing the feedback operation if the feedback operation is required.
