Abstract

A data input device includes a housing which can be grasped by a hand. The housing is equipped with a detecting device that detects a displacement or pressure at a portion of the housing on which fingers are placed when the housing is grasped by the hand. The data input device may include plural sensors to detect displacement or pressure at several different finger belly portions of the fingers. Also, plural sensors may be provided for each finger belly portion. The data input device may be used to control the movement of remotely located mechanical fingers or virtual fingers shown on a display.

Claims

1. A data input device, comprising:

a housing which can be grasped by a hand, wherein the housing is equipped with a detecting means for detecting a displacement or a pressure at a portion of the housing on which fingers are placed at a time of the grasping by the hand, wherein the detecting means provides input data, and

the data input device includes a means for determining an integral value or an incomplete integral value of a force detected by the detecting means, wherein the input data is optionally based on the integral value or the incomplete integral value of the force detected by the detecting means.

2. A data input device according to claim 1, wherein

the integral value or the incomplete integral value is utilized when a value of the force detected by the detecting means exceeds a predetermined value, and

when the value of the force detected by the detecting means is below the predetermined value, the input data is based on the value of the force detected by the detecting means.

3. A data input device according to claim 1, further including an auxiliary input means for inputting information relating to a position and posture of whole fingers.

4. A data input device according to claim 3, wherein the auxiliary input means includes plural axes force detecting means.

5. A data input device according to claim 3, wherein the auxiliary input means and the housing of the data input device are mounted on a common base.

6. A data input device according to claim 5, wherein the housing of the data input device and the auxiliary input means are disposed on the common base such that they are operated by separate hands of one operator.

7. A data input device according to claim 3, wherein the auxiliary input means includes an arm portion and a polyaxes force sensor section, wherein the housing of the data input device is connected to a first end of the arm portion and the polyaxes force sensor section is connected to a second end of the arm portion, such that when an operation is performed to change a position of the data input device, a force corresponding to the operation is applied to the polyaxes force sensor section.

8. A data input device according to claim 1, wherein the housing of the data input device is substantially cylindrical shaped.

9. A data input device according to claim 1, further including a manipulator, wherein the housing of the data input device is mounted at a tip of the manipulator, such that a position and posture of the data input device is movable with plural degrees of freedom.

10. A data input device according to claim 9, further including a repulsive force generator to generate a repulsive force in the data input device.

11. A data input device according to claim 1, wherein the housing of the data input device is substantially cylindrical shaped, and a diameter-adjusting means is provided on the housing for adjusting a size of a diameter of the housing.

12. A data input device according to claim 11, wherein the diameter-adjusting means is provided at a portion of the housing which does not contact the hand when the housing is grasped by the hand.

13. A data input device according to claim 11, wherein the diameter-adjusting means is provided at an outer side of the housing, between a thumb and a little finger when the housing is grasped.

14. A data input device according to claim 11, wherein the substantially cylindrical shaped housing is made from two half cylinders having an elastic body therebetween.

15. A data input device, comprising:

a housing which can be grasped by a hand, wherein the housing is equipped with a detecting means for detecting a displacement or a pressure at a portion of the housing on which fingers are placed at a time of the grasping by the hand, wherein the detecting means detects a value of a force applied by the fingers and provides input data, and

means for determining a maximum value of the force detected by the detecting means, wherein the input data is optionally provided utilizing the maximum value of the force detected by the detecting means for a predetermined period, wherein the maximum value is held by a maximum value-holding circuit.

16. A data input device according to claim 15, wherein

when the value of the force detected by the detecting means exceeds a predetermined value, the maximum value is used to provide the input data, and when the value of the force detected by the detecting means is below the predetermined value, the input data is based on the value of the force detected by the detecting means.

17. A data input device, comprising:

a housing which can be grasped by a hand, and

plural detecting means for detecting a displacement or a pressure, wherein plural detecting means are provided in association with respective parts of the housing with which each finger belly portion to be detected contacts when the housing is grasped, such that the displacement or pressure from each finger belly portion to be detected is detected by plural detecting means, wherein

the data input device determines a value which corresponds to a difference between detected values of two detecting means among the plural detecting means.

18. A data input device, comprising:

a housing which can be grasped by a hand., wherein the housing is equipped with a detecting means for detecting a displacement or a pressure at a portion of the housing on which fingers are placed at a time of the grasping of the housing by the hand, wherein the detecting means provides input data; and

means for calculating a dead zone, wherein the means for calculating the dead zone determines that there is no input when the detected displacement or pressure is below a predetermined value, and wherein a value passed through said means for calculating the dead zone is the input data.

19. A data input device, comprising:

a housing which can be grasped by a hand,

detecting means for detecting a displacement or a pressure provided at a portion of the housing on which fingers are placed when the housing is grasped,

a low-pass filter through which the detected displacement or the pressure is made to pass to filter rapid changes in the detected displacement or pressure, and

means for calculating a dead zone, wherein the means for calculating the dead zone determines that there is no input when the displacement or the pressure passed through the filter is below a predetermined value, wherein

a value passed through the means for calculating the dead zone is determined to be an input value.

20. A data input device, comprising:

a housing which can be grasped by a hand, wherein the housing is equipped with plural detecting means, wherein each detecting means detects a displacement or a pressure at a respective portion of the housing on which a respective finger belly portion between two joints of a finger is placed at a time of the grasping of the housing by the hand, wherein each detecting means detects a resulting value corresponding to the detected displacement or pressure at the respective detecting means; and
