Description

  The present invention relates to a pointing device technique used for designating and selecting desired symbols and icons on a display device screen and inputting position information in an electronic computer system.

  A so-called graphic user interface (commonly referred to as GUI), which performs operations such as command selection and data input to the electronic computer system by moving the pointer or cursor to icons or display figures on the screen of the display device constituting the electronic computer system In general, a device that moves the cursor or pointer on the screen and determines an input at a desired position is generally used. A kind of input device of such an electronic computer system, and a pointer or cursor on the screen of a display device constituting the electronic computer system is moved to be positioned at a desired position on the screen, and the position is further transferred to the electronic computer. A device that performs input for recognition is hereinafter referred to as a pointing device. A mouse is typical as a pointing device, and is currently most widely used. The mouse moves on the plane by hand, and the movement amount and direction are input to the computer by using a ball-type encoder or an image sensor that detects the change in the reflection pattern of the light beam irradiated on the plane. The pointer or cursor on the display screen to be moved is moved according to the amount and direction of the mouse movement, and set to a desired position on the screen. By inputting a click signal when the pointer or cursor reaches a desired position on the screen, the position coordinates or icon on the screen to be selected can be recognized by the electronic computer.

  Although the mouse is usually handled with one hand, it is often necessary to operate the keyboard to enter numbers and text information. When using the mouse, it is necessary to move one hand away from the keyboard and move it to the mouse position. Moving one hand from the middle and the keyboard to the mouse operation position or from the mouse operation position to the keyboard greatly reduces the efficiency of the input operation. Although it is possible to reduce the frequency of use of the mouse by inputting a shortcut key that associates a specific key and icon on the keyboard with each other instead of the mouse, it is not general because it requires labor to learn the hot key. The use of a mouse is based on the premise that at least one hand can move within a certain range, and there are people who have hand movement impairments when they are used by people with disabilities in their hands or when they use a computer. If you use it, you may not be able to use it.

  In order to reduce the time loss associated with switching between using the mouse and using the keyboard, it is possible to change the mouse operation to the keyboard, and vice versa, by placing the mouse that is normally held and operated on a finger. There has been proposed an invention that eliminates the problem. Patent Document 1 proposes a pointing device in which a mouse ball or an image sensor and having a function similar to that of a mouse is attached to a finger of a hand. By always wearing it on the finger, it is said that there is no need to change the keyboard and mouse, and fatigue can be reduced. In addition to Patent Document 1, several similar patent applications such as Patent Document 2 and Patent Document 3 have been filed.

  According to the techniques of Patent Document 1 and Patent Document 2, since the pointing device is always worn on the hand or finger, when switching between using the keyboard and using the pointing device, the hand is temporarily used from the keyboard or from the pointing device. There is no need to release the keyboard, and there is no need to search for the keyboard position or pointing device position, so that the work efficiency can be improved and the effect of reducing fatigue can be expected. However, all of the inventions disclosed in these documents are based on the premise that the pointing device can be moved to a considerable extent on a plane when inputting position information. In many cases, it is not possible to use it for those who cannot expect the effect of improving the efficiency in the end, and who are difficult to move the pointing device by a sufficient distance to input the required position on the screen. There is a case.

Patent Document 4 discloses a technique for moving a pointer to a required position on a screen even with a small movement distance. In Patent Document 4, a conventional mouse-shaped pointing device composed of a material having elasticity, a portion corresponding to the direction in which the pointer or cursor moves with the finger or the like of the resilient material constituting the mouse shape A technique is disclosed in which a pressure is applied to the sensor, the pressure is detected by a force sensor, and a movement direction signal is output. The present disclosure has the effect of not requiring a wide plane for moving the mouse because it is not necessary to move the mouse. At the same time, it can be used by simply applying pressure without moving the mouse-shaped object, so that it is convenient for use by people who have difficulty in moving their hands and arms. However, in the present disclosure, when using the pointing device, it is necessary to release the hand from the keyboard and move the hand to the operation position of the device. Further, since the shape is a conventional mouse shape, pressure is applied to a necessary portion with a finger. It is not possible to use it when a person with a disability in the hand, arm or finger uses it, or when a person whose hand movement is hindered by work in parallel with the use of a computer. In some cases.
JP 2001-236177 A Japanese Patent Application Laid-Open No. 2001-2106068 JP H11-015597 JP H10-222291

  A pointing device that moves and sets the pointer and cursor on the display screen of the electronic computer system to the desired position, selects icons, etc. and inputs position data, and is used by wearing it on the body part of the operator. A device that can detect a minute movement of a wearing part of the pointing device, convert a pointer or a cursor into a signal of a desired movement direction or a desired movement speed if necessary, and input the signal to an electronic computer system. Since it can always be worn and used on the body part, there is no time loss when switching from keyboard operation to pointing device operation and vice versa, and it is not necessary to move the device attachment part greatly. Not only can you select figures and input position data efficiently on the display device of the system, but it can be used without limiting the body wearing part of the operator, so it has obstacles in motor function in the hand. The convenience of using a pointing device is also provided to people who have difficulty in hand movements in parallel with the use of computers and computers.

  FIG. 1 shows one configuration of a pointing device according to the present invention. The pointing device includes a detection unit 1 and mounting means 3 for mounting the detection unit 1 on a predetermined body part. FIG. 1 shows a case in which the pointing device according to the present invention is worn on the wrist, and the movement of the wrist wearing the pointing device is detected by the detection unit 1 and transmitted to the computer system 4 via the signal processing unit 2. . As the mounting means 3 formed by a belt or the like, an appropriate fixing method such as wrapping around a body part can be employed, and a shape and structure suitable for the body part to be mounted can be selected depending on the usage.

  As the attachment mechanism 8 for fixing the detection unit 1 shown in FIG. 2 to the mounting means 3, it is desirable to use a surface fastener or the like that can easily adjust and change the mounting position of the detection unit 1 to the mounting means 3. By using a hook-and-loop fastener or similar as the attachment mechanism 8, the detection unit 1 having the same shape can be used even when the shape and structure of the mounting means 3 are changed to match the body part to be mounted. There is also an advantage of giving versatility.

  In FIG. 2, the detection unit 1 includes a displacement detection mechanism 6 and a housing 7, and the housing 7 is coupled to the mounting means 3 via an attachment mechanism 8. In the example of FIG. 2, the detection unit 1 is configured such that a part of the displacement detection mechanism 6 has a portion protruding from the housing 6 to the outside (hereinafter referred to as a protruding portion 6 a). In the example shown in FIG. 2, the protrusion 6 a is arranged so as to be brought into contact with the external fixed object 5 by moving the wrist which is a body part to which the pointing device of the present invention is attached. The protrusion 6a is configured to be able to move relative to the housing 7, and the housing 7 is moved when the mounting site is moved while the protrusion 6a is kept in contact with the fixed object 5. Therefore, the protruding portion 6 restrained by the frictional force with the fixed portion 5 causes a relative displacement between the housing 7. The displacement generated in this way or the stress generated by the displacement is converted into an electrical signal by a sensor using deformation of an elastic body such as a plurality of strain sensors, force sensors, or pressure sensors incorporated in the detection unit 1.

  Electric signals generated from a plurality of sensors for detecting the force or displacement are synthesized and calculated by the signal processing unit 2 shown in FIG. 1, and output as a signal of the moving direction of the pointer or cursor and, if necessary, the moving speed. The signal is input to the electronic computer system as a pointer or cursor movement direction (including moving speed if necessary) signal displayed on the display screen of the electronic calculation system (indicated by 4 in FIG. 1). As described above, since the minute movement of the body part wearing the pointing device is detected as a minute displacement of the elastic body by the sensor using the deformation of the elastic body, such as the strain sensor, the force sensor or the pressure sensor, An input for moving the pointer or the cursor to a desired position can be performed only by a minute movement of the body part. In addition, since the use of the pointing device of the present invention requires only a minute movement of the body part on which the pointing device is worn, the keyboard can be operated while the pointing device is worn, and the movement of the body is not required. There is also a feature that can be used widely by people who are free and unable to make large movements.

  FIG. 4 shows an example of the configuration of the detection unit 1. In FIG. 4, FIG. 4 a is a diagram represented by projection projection, and 4 b is a diagram illustrating the configuration of the detection unit 1 in a projection diagram. The detection unit 1 includes a housing 13, a displacement detection mechanism 14, and a pressure sensor 15. The displacement detection mechanism 14 includes a detection shaft 14b and a transmission portion 14c configured by a plurality of plate-like pieces projecting symmetrically in a direction perpendicular to the shaft. The detector 1 is attached to the mounting means 3 (not shown in FIG. 4) by an attachment mechanism 8 (not shown in FIG. 4) provided on the casing 25 as a whole. The displacement detection mechanism 14 projects one end of the detection shaft 14b in the opposite direction of the body part to which the pointing device according to the present invention is attached (illustrated as a projecting portion 14a in FIG. 4), and the other end is a spherical surface and a cone. Or it is a similar shape, and it arrange | positions so that it may be supported by the receiving part of a housing as the support part 14d. The support portion 14d maintains the position of the detection shaft 14b in the axial direction when the protrusion 14a comes into contact with an external object and generates a force in the axial direction, and allows a “grinding motion” of the coaxial 14b. Is. The end of the transmission part 14 c is disposed to face the pressure receiving surface of the pressure sensor 15. In order to detect the front and rear, right and left directions in the plane, preferably four pressure sensors 15 or a larger number of pressure sensors 15 are arranged symmetrically with respect to the detection axis 14b as required. The body part to which the pointing device is attached is brought close to an appropriate fixing part 5, for example, the surface of a desk, and the protruding part 14 a is positioned so as to contact the fixing part 5, and the protruding part 14 a and the fixing part 5 The worn body part is moved while maintaining contact. The movement of the mounting part causes a moment to be generated in the detection shaft 14b by the frictional force between the surface of the protrusion 14a and the fixed part 5, and further pressurizes the pressure receiving surface of the pressure sensor 15 through the transmission part 14c. The pressure sensor 15 converts the force applied to the pressure receiving surface as described above into a change in electric resistance.

  FIG. 6 shows another configuration of the detection unit 1. In FIG. 6, the detection unit 1 includes a housing 25, an elastic shaft 24, a pressure sensor 27, and a detection shaft 26. The detector 1 is attached to the mounting means 3 (not shown in FIG. 6) by an attachment mechanism 8 (not shown in FIG. 6) provided on the casing 25 as a whole. One end of the detection shaft 26 protrudes from the housing 25 to the outside, and the other end is supported by the elastic shaft 24. The elastic shaft 24 may be, for example, a rubber or a cylindrical plastic material having elasticity, a winding spring, a metal rod, or the like. A total of four pressure sensors 27 are preferably installed in the longitudinal and lateral directions in the plane, symmetrically with respect to the neutral axis of the elastic shaft 24, but the number can be increased as necessary. The detection shaft 26 has a protruding portion that protrudes to a position facing the pressure receiving surface of each force sensor corresponding to the arrangement of the force sensors. As described above, the body part to which the pointing device including the detection unit 1 shown in FIG. 6 is attached is moved to bring the external fixed object and the tip protruding portion of the detection shaft 26 into contact with each other. When the attached body part is moved while maintaining the contact between the fixed object and the tip protrusion, the detection shaft supported by the elastic shaft is displaced, and as a result of the displacement, the overhanging portion facing the force sensor 27 of the detection shaft 26 corresponds. The force sensor 27 generates an electrical output corresponding to the contacted force.

  FIG. 7 shows another configuration of the detection unit 1. In FIG. 7, the detection unit 1 includes a housing 28, a detection shaft 29, a strain gauge 31, and four beams 30 made of an elastic plate. The detector 1 is attached to the mounting means 3 (not shown in FIG. 7) by an attachment mechanism 8 (not shown in FIG. 7) provided on the casing 28 as a whole. One end of the detection shaft 29 protrudes from the housing 28 to the outside, and the other end is supported by the housing 28 so as to freely rotate. The intermediate portion of the shaft 30 is provided in four directions symmetrical with respect to the axis. Connected to. As described above, the body part to which the pointing device including the detection unit 1 shown in FIG. 7 is attached is moved to bring the external fixed object into contact with the protruding portion of the detection shaft 29. When the mounted body part is moved while maintaining the contact between the fixed object and the protrusion, the detection shaft 29 is displaced, and each of the beams 30 is distorted corresponding to the displacement. The strain gauges 31 individually arranged on the beam 30 convert the strain generated in the beam into an electrical output corresponding to the displacement of the detection shaft 29.

  FIG. 8 shows another configuration of the detection unit 1. In FIG. 8, the detection unit 1 includes a casing 32, a detection shaft 33, a pressure sensor 35, and an elastic plate member, and includes a diaphragm 34 provided with a waveform. The detector 1 is attached to the mounting means 3 (not shown in FIG. 8) by an attachment mechanism 8 (not shown in FIG. 8) provided on the casing 32 as a whole. One end of the detection shaft 33 protrudes from the housing 32 to the outside, and the other end is supported by the housing 32 so as to be freely rotatable. An intermediate portion of the shaft is connected to the diaphragm 34 extending symmetrically with respect to the axis. The As described above, the body part to which the pointing device including the detection unit 1 shown in FIG. 8 is attached is moved to bring the external fixed object into contact with the protruding portion of the detection shaft 33. When the wearing body part is moved while maintaining the contact between the fixed object and the protrusion, the detection shaft 33 is displaced relative to the housing 32 and deforms the diaphragm 34. The detection shaft 33 is a pressure sensor 35 that protrudes in four directions symmetrical with respect to the axis at the intermediate portion and is attached to the housing 32, and includes four pressure sensors 35 arranged on the axis around the detection shaft 33. A portion facing the pressure receiving portion is provided. Due to the relative displacement of the detection shaft 33 with respect to the housing 32, the protruding portion of the detection shaft 33 pressurizes the pressure sensor 35 and converts it into an electrical output corresponding to the relative displacement of the detection shaft 33.

  FIG. 9 shows another configuration of the detection unit 1. In FIG. 9, the detection unit 1 is made of a housing 36, a detection shaft 38, a pressure sensor 37, and an elastic plate material, and includes a bellows 39 having a bellows cylindrical shape. The detector 1 is attached to the mounting means 3 (not shown in FIG. 9) by an attachment mechanism 8 (not shown in FIG. 9) provided on the housing 36 as a whole. One end of the detection shaft 38 protrudes from the housing 38 to the outside, and the other end is supported by the housing 36 so as to freely rotate. The shaft and the housing 38 are connected through the cylindrical bellows 39. As described above, the body part to which the pointing device including the detection unit 1 shown in FIG. 9 is attached is moved to bring the external fixed object and the protruding portion of the detection shaft 38 into contact with each other. When the mounted body part is moved while maintaining the contact between the fixed object and the protrusion, the detection shaft 38 is displaced relative to the housing 36 and deforms the cylindrical bellows 39. The detection shaft 38 protrudes in four directions symmetrical with respect to the axis at an intermediate portion, and is a pressure sensor 37 attached to the housing 36, and includes four pressure sensors 38 arranged on the axis around the detection shaft 38. A portion facing the pressure receiving portion is provided. Due to the relative displacement of the detection shaft 38 relative to the housing 36, the protruding portion of the detection shaft 38 pressurizes the pressure sensor 37 and converts it into an electrical output corresponding to the relative displacement of the detection shaft 38.

  As described above, the detection unit 1 according to the present invention is a displacement detection mechanism that is connected to a body part that follows the movement of the body part to which the pointing device of the present invention is attached, and elastic means. A part of the housing has a portion protruding to the outside of the housing, the projecting portion is brought into contact with an externally fixed object, and the body and the displacement detecting mechanism are moved by moving the body part attached with the pointing device while maintaining the contact. Relative displacement generated between them is converted into a deformation of an elastic body connecting the housing and the displacement detection mechanism, and the deformation is further converted into an electric signal by a pressure sensor, a strain gauge or the like. Because such a detector can specify the movement direction and position of pointers, cursors, etc. by the movement of the wearing body part, it can be attached to a belt, etc., and a wide range of use parts can be selected, including body parts with large movement restrictions. There is a characteristic. Also, a hook-and-loop fastener is attached to the detection unit on the body part (a belt, a wristwatch band, a part of the elastic ring lacking a part and fitted into the body part, etc.) If it is made detachable by using a hook or a hook, the detection unit itself has the same configuration and shape and has a versatility that can be attached to many different body parts.
