Abstract

<P>PROBLEM TO BE SOLVED: To provide a mouse apparatus and a pointing apparatus, which may implement control in accordance with an operator's intention. <P>SOLUTION: When the palm rest is moving and the mouse 76 is lifted by the fingers, the mouse apparatus is set to a slow repeating mode since a mouse 76 is lifted by fingers under the condition to fix a wrist on a palm rest (further, on a desk on which the mouse is located). For instance, a position of the mouse can be moved base on a relative moving distance and in the moving direction of the palm rest 80 for the mouse even if the mouse 76 is lifted and the mouse ball is not rotating. On the other hand, when the mouse is not lifted by the fingers (and the palm rest is relatively moving in relation to the desk), the mouse is set to a slow speed mode since the wrist is fixed to the palm rest and a tip of the finger operates the mouse 76. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a pointing device and a mouse device, and more particularly to a pointing device and a mouse device that move a specific position displayed on a display means.

  2. Description of the Related Art Conventionally, a pointing device, for example, a mouse is configured such that a built-in mouse ball can be rotated with the movement of a main body in order to move a cursor position displayed on a display.

  On the other hand, the operator may operate the mouse with a fingertip, or may operate the wrist, arm, or the like. This is because the mouse only moves the amount of rotation of the mouse ball, so that it is necessary to increase the amount of rotation of the mouse ball to move the cursor position greatly.

  Recently, a personal computer (hereinafter, referred to as a personal computer) that can arbitrarily set the amount of movement of the cursor position corresponding to the amount of rotation of the mouse ball has been proposed.

  However, if the amount of movement of the cursor position corresponding to the amount of rotation of the mouse ball is set to be large, it becomes difficult to move the cursor position finely. Conversely, if the movement amount of the cursor position corresponding to the rotation amount of the mouse ball is set to be small, the mouse ball must be rotated more in order to move the cursor position greatly. Thus, the conventional pointing device cannot control a specific position such as a cursor position in accordance with the intention of the operator.

  If the desired position is not reached even after moving the mouse body and moving the cursor position, the mouse is lifted back to the original position and the same processing is repeated, but the same processing is repeated. This also makes it difficult to control a specific position such as the cursor position in accordance with the operator's intention.

  Furthermore, the conventional mouse cannot reflect other intentions of the operator other than the purpose of moving the cursor position.

  In addition, the conventional mouse cannot accurately reflect the intention of the operator who wants to move the specific position along, for example, a line with high accuracy, that is, the intention of the operator who wants to input a straight line.

  The present invention has been made in view of the above-described facts, and an object of the present invention is to propose a pointing device and a mouse device that can realize control according to an operator's intention.

  The first moving means according to the first aspect of the invention moves the specific position displayed on the display means by moving the mouse ball, and the second moving means is the specific position displayed on the display means. Is moved by relatively moving at least one of the main body and the operation reference plane.

  The determining means determines whether or not the main body is lifted.

  Here, when the operator lifts the main body, the specific position cannot be moved to the desired position even if the mouse ball is moved to move the specific position, and the operator wants to move the specific position. In this case, the intention of the operator cannot be reflected only by further moving the mouse ball to move the specific position.

  Therefore, when the determining means determines that the main body is not lifted, the control means controls the specific position based on the amount of movement of the mouse ball by the first moving means, and the determining means lifts the main body. If it is determined, the specific position is controlled based on the relative movement amount of at least one of the main body and the operation reference surface by the second moving means.

  As described above, when it is determined that the main body is lifted, the specific position is controlled based on the relative movement amount of at least one of the main body and the operation reference plane, so that the specific position can be specified even when the mouse ball is not moving. The position can be moved, and the specific position displayed on the display means can be controlled according to the operator's intention.

  According to a second aspect of the present invention, the detecting means detects the tilted state of the main body. Here, a plurality of mouse balls are provided at a plurality of locations on the main body, and the detecting means detects the tilt state of the main body by detecting which of the plurality of mouse balls is moving.

  The command means instructs the size to be in accordance with the inclination state of the main body detected by the detection means. Here, a moving means for moving the specific position displayed on the display means by moving the mouse ball is provided, and the above processing is performed for the moving amount of the specific position corresponding to the moving amount of the mouse ball by the moving means. The process is to set the size. That is, the commanding unit instructs the moving amount of the specific position corresponding to the moving amount of the mouse ball by the moving unit to be a size corresponding to the inclination state of the main body detected by the detecting unit.

  In this way, since the command is given so as to be in accordance with the inclination state of the main body by the operator, the intention of the operator can be reflected.

  In the invention according to claim 3, a plurality of mouse balls are arranged at a plurality of locations on the main body. The plurality of mouse balls include a specific mouse ball for moving a specific position displayed on the display means.

  The detecting means detects the amount of movement of each of the plurality of mouse balls.

  The calculating means calculates the turning radius of the main body based on the amount of movement of each of the plurality of mouse balls detected by the detecting means.

  The control means controls the movement amount of the specific position corresponding to the movement amount of the specific mouse ball to be an amount determined by the turning radius calculated by the calculation means.

  Here, the smaller the amount of movement at the specific position, the smaller the turning radius of the main body. In other words, when the operator wants to move the specific position finely, the wrist is fixed and the main body is moved only by the fingertip, so that the turning radius of the main body is reduced, and conversely, the specific position is moved largely. Since the main body is moved by the whole hand, the turning radius of the main body is increased.

  As described above, the movement amount of the specific position corresponding to the movement amount of the specific mouse ball is set to the amount determined by the turning radius of the main body, so that the operator's intention can be reflected.

  In the invention according to claim 4, a plurality of mouse balls are arranged at a plurality of locations on the main body. The plurality of mouse balls include a specific mouse ball for moving a specific position displayed on the display means.

  The detecting means detects the amount of movement of each of the plurality of mouse balls.

  The calculating means calculates the turning radius of the main body based on the amount of movement of each of the plurality of mouse balls detected by the detecting means.

  Then, the correcting means corrects the trajectory of the specific position corresponding to the trajectory of the curvature less than the predetermined value of the specific mouse ball based on the turning radius calculated by the calculating means so as to be a straight line.

  Here, in order to move the mouse ball so that the locus of the specific position displayed on the display means is a straight line, the locus of the specific mouse ball needs to be a straight line.

  However, when the operator moves the mouse body only with the fingertip, the palm becomes the center of rotation, the trajectory of a specific mouse ball becomes a curve, and when the mouse body is moved by hand, the elbow is the center of rotation. Thus, the locus of a specific mouse ball tends to become a curve. That is, a curved line having a curvature less than a predetermined value is input although a straight line should be input.

  On the other hand, the radius of the curve of the trajectory of a specific mouse ball when the mouse body is moved only with the fingertip is shorter than the radius of the curve of the trajectory of the specific mouse ball when the mouse body is moved by hand.

  Therefore, based on the turning radius calculated by the calculation means, it is possible to correct the trajectory of the specific position corresponding to the trajectory of the curvature less than the predetermined value of the specific mouse ball to be a straight line.

  Thus, based on the turning radius calculated by the calculation means, the locus of the specific position corresponding to the locus of curvature of the specific mouse ball that is less than the predetermined value is corrected so as to be a straight line. The intention of the operator can be reflected.

  As described above, according to the present invention, when the present invention determines that the main body is lifted, the specific position is controlled based on the relative movement amount of the main body with respect to the operation reference plane, so that the mouse ball moves. The specific position can be moved even in a state where it is not, and the specific position displayed on the display means can be controlled according to the intention of the operator.

  According to the present invention, a process determined according to the tilt state of the main body by the operator is instructed, so that the operator's intention can be reflected.

  In the present invention, the movement amount of the specific position corresponding to the movement amount of the specific mouse ball is set to an amount determined by the turning radius of the main body, so that the intention of the operator can be reflected. It has the effect.

  The present invention corrects the trajectory of the specific position corresponding to the trajectory of the curvature less than the predetermined value of the specific mouse ball based on the turning radius calculated by the calculating means so that the straight line is moved. It is possible to reflect the intention of the operator.

  A first embodiment of the present invention will be described.

  As shown in FIG. 1, in the first embodiment, a mouse 76 having a mouse ball 92 (see also FIG. 2) connected to a personal computer 74 will be described as an example.

  A palm rest 80 is pivotally supported on the mouse 76 via a shaft 78 so as to be rotatable. The mouse 76 according to the present embodiment includes a relative position sensor 83 that detects the relative movement amount of the palm rest 80 with respect to the mouse. The mouse ball 92, the X encoder 94, and the Y encoder 96 constitute the first moving means according to the first aspect of the invention, and the relative position sensor 83 constitutes the second moving means.

  As shown in FIG. 2, the control system of the mouse 76 includes a control unit 84. The control unit 84 includes an input / output unit 86, a calculation unit 88, and a memory 90. The input / output unit 86 includes click switches 98 and 100, an X encoder 94 for inputting a predetermined relative movement amount (rotation amount) of the mouse ball 92 in the X direction, and the Y direction of the mouse ball 92 (perpendicular to the X direction). A Y encoder 96, a relative position sensor 83, and a personal computer 74 for inputting a relative movement amount (rotation amount) are connected. A relative movement amount (rotation amount) of the mouse ball 92 in the X direction and the Y direction is input from the mouse 76 to the personal computer 74.

  FIG. 3 shows a mode setting process routine of the mouse device according to the first embodiment. In step 116 of FIG. 3, it is determined from the output of the relative position sensor 83 whether or not the palm rest is relatively moving. If it is determined that the palm rest is moving, the mouse 76 is lifted with a finger by determining in step 118 whether the mouse ball is moving from the outputs of the X encoder 94 and the Y encoder 96. Judge whether or not. Note that a mechanical switch for detecting the push-up of the mouse ball may be provided, and it may be determined whether or not the mouse 76 is lifted with a finger based on the on / off state of the mechanical switch.

  The case where the mouse 76 is lifted with a finger is a case where even if the mouse ball is moved and the cursor position is moved, the cursor position cannot be moved to the desired position yet, and it is desired to move it further. In this case, the intention of the operator cannot be reflected only by further moving the mouse ball to move the specific position.

  Therefore, when the palm rest is moved and the mouse 76 is lifted by the finger, the mouse 76 is lifted by the finger while the wrist is fixed to the palm rest (for example, a desk or the like on which the mouse is placed). In step 122, a slow iteration mode is set. That is, even if the mouse 76 is lifted and the mouse ball does not rotate, the cursor position is moved based on the relative movement amount and movement direction of the palm rest 80 with respect to the mouse.

  On the other hand, when the mouse 76 is not lifted by the finger (and when the palm rest is relatively moved), the wrist is fixed to the palm rest and the mouse 76 is operated by the fingertip. To set the low speed mode.

  If it is determined in step 116 that the palm rest has not moved, it is determined in step 124 whether or not the mouse 76 is lifted with a finger as described above.

  When the palm rest is not moved and the mouse 76 is lifted by a finger, the palm rest is not moved, and thus the mouse 76 and the palm rest 80 are lifted and moved by hand. In this case, even if the mouse ball is moved and the cursor position is moved, the cursor position still cannot be moved to the desired position, and the operator wants to move it further. However, the operator moves the cursor position more. Therefore, it can be determined that the mouse 76 and the palm rest 80 are lifted and moved.

  Therefore, if the palm rest is not moving and the mouse 76 is lifted with a finger, a fast repetition mode is set at step 126. That is, the cursor position is moved based on the relative movement amount of the palm rest 80 with respect to the mouse, but the movement amount of the cursor position with respect to the unit relative movement amount of the palm rest 80 is increased compared to the slow repeat mode in step 122.

  When the mouse 76 is not lifted by a finger (and the palm rest is not relatively moved), the wrist is lifted from the palm rest (further, the desk on which the mouse is placed, for example), and the mouse is moved with the entire hand. In this case, in step 128, the normal mode (the movement amount of the cursor position with respect to the unit movement amount of the mouse ball is larger than that in the low speed mode) is set.

  Here, the fast repeat mode and the slow repeat mode are canceled when the ball is in a grounded state.

  Thus, when it is determined that the main body is lifted, the cursor position is moved based on the relative movement amount of the palm rest 80 with respect to the mouse, so that the cursor position can be moved even when the mouse ball is not moved, Control according to the operator's intention can be realized.

  Steps 120, 122, 126, and 128 correspond to the control of the control means of claim 1. Note that the processing of steps 120, 122, 126, and 128 may be executed by the control unit 84 of the mouse 76 as described above, or may be executed on the personal computer side.

  Although the palm rest is used in the first embodiment described above, the present invention is not limited to this, and a mouse pad 85 may be used instead of the palm rest as shown in FIG.

  In this case, the mouse pad 85 communicates with the mouse 76 in a wired or wireless manner, and the relative movement amount of the mouse pad 85 with respect to the mouse, that is, the relative movement amount of the center of gravity position of the wrist on the mouse pad 85 with respect to the mouse. Provide a sensor to detect.

  In the above, instead of connecting the mouse and the personal computer, the mouse pad and the personal computer may be connected. Further, power to the mouse body may be supplied by electromagnetic coupling with the mouse pad.

  Next, a second embodiment of the present invention will be described. Since this embodiment has substantially the same configuration as that of the first embodiment described above, only different parts will be described. That is, as shown in FIG. 5, the mouse 76A according to the present embodiment is different in that it includes two mouse balls 92F and 92R, one in each of the front and rear. Further, as shown in FIG. 6, the control system of the mouse 76A according to the present embodiment is also different in that each of the mouse balls 92F and 92R includes an X encoder 94F, 94R, and a Y encoder 96F, 96R.

  FIG. 7 shows a mode setting process routine of the mouse device according to the second embodiment. In step 130 of FIG. 7, it is determined whether or not the movement amount is input only from the mouse ball 92F arranged on the front side. As described above, since the mouse 76A is provided with one mouse ball 92F and 92R on the front and rear, the movement amount is input only from the mouse ball 92F arranged on the front side. This is a case of tilting forward. Therefore, in step 130, it is substantially determined whether or not the mouse 76A is tilted forward.

  If the movement amount is not inputted only from the mouse ball 92F arranged on the front side, it is determined in step 132 whether or not the movement amount is inputted only from the mouse ball 92R arranged on the rear side. That is, it is determined whether or not the mouse 76A is tilted rearward.

  When the movement amount is input only from the mouse ball 92F arranged on the front side, the high speed mode is set in step 134, and when the movement amount is inputted only from the mouse ball 92R arranged on the rear side. In Step 136, the low speed mode is set, and when the movement amount is input from the mouse balls 92F and 92R arranged on the front side and the rear side, the medium speed mode is set in Step 138.

  Steps 134, 136, and 138 correspond to the processing of the command unit according to claim 2. Note that the processing of steps 134, 136, and 138 may be executed by the mouse 76 or the personal computer as described above.

  In the example described above, the movement amount of the cursor position corresponding to the movement amount of the mouse ball is set by the mouse ball that has input the movement amount, but the present invention is not limited to this, You may process as shown in FIG.

  That is, when the movement amount is inputted only from the mouse ball 92F arranged on the front side, in step 140, a mode for scrolling the window displayed on the display screen of the personal computer is set and arranged on the rear side. If the movement amount is input only from the mouse ball 92R, the mode for selecting the menu is set in step 142, and the movement amount is input from the mouse balls 92F and 92R arranged on the front side and the rear side. In this case, it is possible to return at step 144, that is, return to the mode in which the cursor position is moved in response to the movement of the mouse ball.

  Steps 140, 142, and 144 correspond to the processing of the command unit of claim 2. Note that the processing of steps 140, 142, and 144 may be executed by the mouse 76 or the personal computer as described above.

  In this way, since the process is determined according to the tilt state of the main body by the operator, the operator's intention can be reflected.

  The above modes are merely examples, and different processes may be executed.

  Further, in the above-described embodiment, the bottom surface of the mouse is a single plane, but the present invention is not limited to this, and as shown in FIG. The rear tilt surface 76BR may be formed so that 76BF and the mouse are easily tilted rearward.

  Furthermore, in the above-described embodiment, two mouse balls 92F and 92R, one each in front and rear, are provided, but the present invention is not limited to this, and a plurality of mouse balls may be provided. Conversely, as shown in FIG. 10, a single mouse ball may be provided. Here, when a single mouse ball is provided, the front tilt surface 76BF and the rear tilt surface 76BR are formed so that the mouse can be tilted forward easily and the mouse is easily tilted backward, and 11, a front tilt switch 146 that is turned on when the mouse is tilted forward and a rear tilt switch 148 that is turned on when the mouse is tilted rearward may be provided.

  Next, a third embodiment of the present invention will be described. Since the present embodiment has the same configuration as the second embodiment described above, the description thereof is omitted.

  Here, the calculation principle of the present embodiment will be described with reference to FIG.

  As shown in FIG. 12A, when a single mouse ball is provided, when the mouse moves from the position indicated by the solid line to the position indicated by the imaginary line, the X displacement and Y displacement of the mouse ball Is entered.

  On the other hand, in the present embodiment, as shown in FIG. 12B, the mouse is provided with two mouse balls F and R before and after, so that the position indicated by the imaginary line from the position indicated by the solid line. Is moved, the X displacement and Y displacement of each mouse ball are input.

  Accordingly, the trajectories (1) and (2) of the mouse balls F and R (see also FIG. 12C) can be calculated, and the X displacement and Y displacement of each mouse ball can be combined (averaged). The locus (3) of the intermediate position of each mouse ball can be calculated.

  Furthermore, when a single mouse ball is provided, it is impossible to determine in what direction the mouse is moving, but when two mouse balls F and R are provided, Since it is known in which direction the mouse is moving, the coordinates of an arbitrary position (4) can be calculated from the X displacement and Y displacement of each mouse ball. Furthermore, the turning radius and the turning center (5) of the mouse can be calculated from the trajectories (1) and (2) of the mouse balls F and R.

  In the present embodiment, as shown in FIG. 13A, the corner portion of the mouse 76 is formed as a projection as the index portion 75A, or the projection is drawn out as the index portion 75A to the corner portion of the mouse 76. Alternatively, as shown in FIG. 13B, an opening is formed in the center of the mouse 76 as an index portion 75B.

  Since the coordinates of the arbitrary position (4) can be calculated from the X displacement and Y displacement of each mouse ball as described above, the index region 75A or the index can be calculated from the X displacement and Y displacement of each mouse ball. The coordinates of the part 75B are calculated and input to the personal computer.

  That is, if the index part 75A or the index part 75B is moved along a line (for example, a straight line (or may be a curve)) as shown in FIGS. It is possible to input, and the cursor position can be moved linearly.

  In this way, two mouse balls are arranged, and the movement amount of the predetermined index part of the main body is calculated as the movement amount of the cursor position based on the movement amount of the two mouse balls. If the indicated index portion is moved along the line, the cursor position can be moved along the line with high accuracy, and the operator's intention to move the cursor position along the line with high accuracy can be obtained. It can be reflected.

  Next, a fourth embodiment of the present invention will be described. Since the present embodiment has the same configuration as that of the third embodiment described above, the description thereof is omitted. In the present embodiment, the cursor position is moved based on the movement of the mouse ball arranged on the front side. Then, the movement amount of the cursor position corresponding to the unit movement amount of the mouse ball arranged on the front side is set based on the turning radius of the main body.

  FIG. 14 shows a mode setting processing routine of the mouse device according to the present embodiment. In step 152 of FIG. 14, the turning radius R of the mouse is calculated from the trajectories (1) and (2) of the mouse balls F and R.

  Here, the smaller the amount of movement of the cursor position, the smaller the turning radius of the main body. In other words, when the operator wants to move the cursor position finely, the wrist is fixed and the main body is moved only with the fingertip, so that the turning radius of the main body becomes small, and conversely, the cursor position needs to be moved largely. Since the main body is moved by the whole hand, the turning radius of the main body is increased.

  Therefore, in step 154, it is determined whether or not the turning radius R is greater than or equal to the threshold value R0. If the turning radius R is greater than or equal to the threshold value R0, the high-speed mode is set in step 156 and the turning radius is set. If the radius R is less than the threshold value R0, the low speed mode is set in step 158.

  Steps 156 and 158 correspond to the control of the control means of claim 3. Note that the processing of steps 156 and 158 may be executed by the mouse side or the personal computer side as described above.

  In this embodiment, two types of high speed mode and low speed mode are set. However, the present invention is not limited to this, and a plurality of speed modes can be set according to a plurality of turning radii, The speed may be controlled to increase as the moving radius increases.

  Next, a fifth embodiment of the present invention will be described. Since this embodiment has the same configuration as that of the above-described fourth embodiment, description thereof is omitted.

  FIG. 15 shows a horizontal correction processing routine of the mouse device according to the fifth embodiment.

  In step 164, the amount of movement of the mouse ball (trajectory over a predetermined distance) (see FIG. 16C) is taken in, and in step 166, the turning radius R is calculated as described above, and the turning radius R is It is determined whether or not the trajectory is a substantially horizontal trajectory by determining whether or not the trajectory of a predetermined distance or more is a threshold value that can be determined as a substantially horizontal trajectory. That is, it is determined whether the curvature of the locus is less than a predetermined value.

  If it can be determined that the locus is a curve, the present process is terminated. If it is determined that the locus is a substantially straight line, in step 168, whether or not the turning radius R is equal to or greater than a threshold value R0. If the turning radius R is greater than or equal to the threshold value R0, a small correction table (see FIG. 16B) is selected in step 170, and the turning radius R is less than the threshold value R0. In step 172, the large correction table (see FIG. 16A) is selected.

  That is, when the turning radius is small, the curvature of the locus is larger than when the turning radius is large. Therefore, when the turning radius is small, a large correction table (see FIG. 16A) with a higher degree of correction is selected than when the turning radius is large.

  In step 174, the correction value of the Y value corresponding to each X value is read from the selected correction table, the Y value is corrected, and each X value and the corrected value corresponding to each X value are corrected. Output Y value to PC.

  Steps 170 to 174 correspond to the control of the control means of claim 4. Note that the processing of steps 170 to 174 may be executed by the mouse side or the personal computer side as described above.

  Thus, based on the turning radius, the locus of the cursor corresponding to the locus of curvature less than the predetermined value of the mouse ball is corrected to be a straight line, so that the intention of the operator trying to move the straight line is reflected. Can be made.

  In this embodiment, two types of large correction table and small correction table are stored. However, the present invention is not limited to this, and a plurality of correction tables are stored according to a plurality of turning radii. Cursor position corresponding to the locus of curvature less than the predetermined value of the mouse ball is corrected so that the locus of the cursor position corresponding to the locus of curvature of the mouse ball less than the predetermined value becomes a straight line, or based on the turning radius You may make it correct | amend so that the locus | trajectory may become a straight line.

  It should be noted that a plurality of the processes of the third to fifth embodiments described above may be combined.
