  In an information processing apparatus such as a general PC (Personal Computer), a user performs an operation such as moving a pointer displayed on a PC monitor by using a pointing device such as a mouse as shown in FIG. However, in order to appropriately move the pointer on the monitor screen in the direction assumed by the user using the pointing device, the user needs to hold the pointing device in a specific direction set for each pointing device. Therefore, in order to perform an operation, the user must visually check the pointing device, try to grasp the pointing device, and check whether the pointer on the screen can be moved as desired by the user. There was a problem of becoming.

  Also, as a pointing device, by using communication with the information processing device wirelessly, a device that is used in the air by holding it with a hand is proposed, unlike a mouse that is used on a plane such as a desk. ing. However, in order to appropriately move the pointer on the monitor screen in the direction assumed by the user using these pointing devices, the user holds the pointing device in a specific direction set for each pointing device as described above. There was a need. Therefore, there has been a problem that the above-mentioned problem cannot be solved yet.

  Furthermore, in recent years, spherical or hemispherical touch input devices that can be used in all directions have been proposed. In such a touch-type input device, by mounting a touch pad on the input device body, it is possible to detect the contact of the user's finger and move the pointer on the monitor screen according to the movement of the finger. However, even in the case of a touch type input device, in order to move the pointer on the monitor screen appropriately in the direction assumed by the user, in the same manner as described above, the user must use a specific direction set for each touch type input device. It was necessary to hold each touch-type input device. In addition, since a spherical or hemispherical input device can be gripped from various directions, it is difficult for the user to recognize the appropriate direction to be gripped. Therefore, the user touches in a specific direction set for each touch-type input device. There was also a problem that it was difficult to hold the mold input device. For this reason, there is a problem that the operation becomes more complicated than the above pointing device.

In the technique described in Patent Document 1, it is possible to detect an operation such as stroking with the palm by detecting a plurality of points where the palm of the user contacts and detecting the position of the center of gravity.

  The contact detection unit 11 uses the touch module 1 to detect contact of the user's finger or palm to the input device 100. The fixed position detection unit 12 distinguishes and detects a moving contact point and a fixed contact point among the contacts detected by the contact detection unit 11. When the contact detection unit 11 detects contact of a surface having a predetermined area or more, the center of gravity of the contact surface may be calculated, and the center of gravity may be set as a moving contact point or a fixed contact point.

  The direction determination unit 13 determines the direction in which the user is holding the input device 100 from the positional relationship between the moving contact point and the fixed contact point. For example, the direction determination unit 13 uses the fact that the user generally holds the input device with the thumb, middle finger, and palm and operates with the index finger, and the fixed position detection unit 12 detects the fixed contact point. By determining the contact point of the palm, the user's operation direction can be determined. The details of the direction determination process of the direction determination unit 13 will be described later.

(Operation output processing)
FIG. 7 shows an example of the flow of operation output processing in the input device according to this embodiment. Below, the example of the flow of the operation output process in the input device 100 which concerns on this embodiment is demonstrated using the flowchart shown in FIG.

  When the user grips the input device 100 to operate the information processing device 200, the contact detection unit 11 of the input device 100 causes the user's finger or palm to come into contact with the detection area of the input device due to a change in capacitance. Is detected (step S701).

  The fixed position detection unit 12 detects a fixed region and a moving region among regions detected when the user's finger or the like is in contact, and uses the region that is fixed and in contact as a fixed contact point. Detection is performed (step S702). At this time, when the area of the fixed region is equal to or larger than a predetermined value, the center of gravity of the region is calculated, and the calculated center of gravity is detected as a fixed contact point. Note that the method of determining the fixed contact point when the area of the fixed region is equal to or greater than a predetermined value is not limited to the method of calculating the center of gravity, and any method can be applied.

  The direction determination unit 13 determines the direction in which the user is holding the input device 100 based on the positional relationship between the moving contact point and the fixed contact point detected by the fixed position detection unit 12 as described above (step S703). ) And determine the user's operation direction.

  Next, when the movement detection unit 14 detects the locus of the moving contact point (step S704), the operation direction correction unit 15 determines the direction of the detected locus based on the operation direction of the user determined by the direction determination unit 13. Correction is performed (step S705). Then, the output unit 16 outputs the user operation input corrected by the operation direction correction unit 15 to the information processing apparatus 200 (step S706).

  The user operation output as described above is received by the input unit 23 of the information processing apparatus 200. Then, the information processing apparatus 200 causes the control unit 21 to reflect the user's operation on the display apparatus 300, and realizes, for example, a pointer movement on the screen of the display apparatus 300. Note that the processing in step SS703 and step S705 can be performed by the control unit 21 on the information processing apparatus 200 side, and is not particularly limited.

  In addition, when the user's operation direction determined by the direction determination unit 13 is different from the operation direction actually felt or desired by the user, the user finely adjusts the operation direction with respect to the operation direction correction unit 15. The content may be input. In this case, by storing the fine adjustment content in a storage unit (not shown), the operation direction correction unit 15 can perform fine adjustment of the operation direction for each user as needed when correcting the direction of the detected locus.

(Direction determination processing)
Next, details of the fixed position detection process in step S702 and the direction determination process in step S703 will be described with reference to the flowchart shown in FIG.

  When the contact detection unit 11 detects contact of the user with the input device 100 (step S801), the fixed position detection unit 12 determines whether or not the area of the region in contact with the user is equal to or greater than a predetermined value. Determines whether to be a point or a face. Here, when the area of the contact area by the user is equal to or greater than a predetermined value, it is determined as a surface, and when the area of the contact area is equal to or less than the predetermined value, it is determined as a point. However, the present invention is not limited to this. The predetermined value may be set in advance or may be set by the user.

  When it is determined that there is a surface in the contact detected as described above (step S802 / YES), the fixed position detection unit 12 calculates the center of gravity of the contact surface (step S803), and uses the center of gravity as the contact point. To do. On the other hand, when it is determined that the detected contact has no surface (step S802 / NO), the fixed position detection unit 12 uses the point detected by the contact detection unit 11 as a contact point as it is for the next processing. . Note that the method of determining the contact point when the area of the contact region is equal to or larger than the predetermined value is not limited to the method of calculating the center of gravity, and any method can be applied. Alternatively, the contact point position may be determined by detecting all areas where the user's finger or the like is in contact as surfaces and calculating the center of gravity in all the contact areas.

  Next, the fixed position detection unit 12 determines whether each detected contact point is a fixed contact point that is a fixed contact point or a moving contact point that is a moving contact point (step S804). ). When the fixed contact point is determined, the direction determining unit 13 determines the direction in which the user grips the input device 100 from the positional relationship between the fixed contact point and the moving contact point, and the up and down direction for the user. A direction is determined (step S805). Then, the direction determining unit 13 determines the left / right direction for the user based on the up / down direction determined as described above (step S806).

  Here, the direction determination method for determining the user's operation direction in steps S804 to S806 will be described. The direction determination method shown below is an example, and the direction determination method is not limited to this.

  For example, as shown in FIG. 9, the user generally holds the input device 100 with the thumb, middle finger, and palm and operates with the index finger. Therefore, when the palm contact point is determined from the fixed contact points detected by the fixed position detection unit 12, the direction determination unit 13 determines the vertical direction with the palm contact point as the downward direction for the user. Can do. More specifically, a line connecting the contact point between the thumb and the middle finger is defined as the X axis (left and right direction), and a line perpendicular to the line connecting the contact point between the thumb and the middle finger is defined as the Y axis. At this time, since the contact point of the palm is present on the user side as compared with the moving contact point, the contact point of the palm is downward for the user. When the downward direction is determined in this way, the left and right on the X axis are also determined, and the operation direction for the user can be accurately detected and determined.

  Here, a method of detecting which of the fixed contact points is a downward contact point for the user will be described with reference to FIGS. 9 and 10. That is, a method for determining which fixed contact point corresponds to the palm contact point will be described. The direction determination method described below is an example, and the method for determining the operation direction for the user is not limited to the following method. For example, the direction determination method can be appropriately changed based on the shape of the input device.

  First, as a first downward direction determination method, there is a method of determining a fixed contact point that is located farthest from the moving contact point as a palm contact point. In this method, the fixed position detection unit 12 calculates the distance between each moving contact point (for example, forefinger) and each fixed contact point (for example, thumb, middle finger, palm) and exists at a position farthest from the moving contact point. The fixed contact point to be used is the palm contact point. And the direction determination part 13 determines a downward direction for a user from the positional relationship with each contact point based on the contact point of a palm. In other words, the direction determination unit 13 uses a line connecting fixed contact points other than those detected as palm contact points as the X axis, and the side having the palm contact point on the Y axis perpendicular to the X axis is the user. Decide as a downward direction for

  As a second downward direction determination method, among the lines connecting the fixed contact points, the fixed contact points that are not included in the lines intersecting the moving contact points and the fixed contact points are contacted by the palm. There is a method of judging a point.

  In this method, as shown in FIG. 10, first, assuming that the moving contact point is point A, the three fixed contact points are point B, C point, and D point, the fixed position detecting unit 12 sets the fixed contact points to each other. The positional relationship between the knot, line segment BC, line segment CD, and line segment BD is detected. In FIG. 10, a line connecting the fixed contact points is indicated by a dotted line. Next, the fixed position detection unit 12 connects the moving contact point (point A) and each fixed contact point (points B to D), and detects the positional relationship between the line segment AB, the line segment AC, and the line segment AD. . And the fixed position detection part 12 detects the fixed contact point which is not included in the line which connected each moving contact point and each fixed contact point among the lines which connected each fixed contact point, The contact point of the palm. And the direction determination part 13 determines a downward direction for a user from the positional relationship with each contact point based on the contact point of a palm.

  Specifically, in the example illustrated in FIG. 10, among the line segment BC, line segment CD, and line segment BD, a line where the line segment AB, line segment AC, and line segment AD intersect is the line segment BD. That is, the fixed position detection unit 12 determines that the point C which is a fixed contact point not included in the line segment BD is a palm contact point. In addition, the direction determination unit 13 uses a line segment BD, which is a line connecting fixed contact points other than those detected as palm contact points, as an X axis, and a palm contact point among Y axes perpendicular to the X axis. The side with (C point) is determined as the downward direction for the user.

  The first downward direction determination method can determine the downward direction very easily, whereas the second downward direction determination method determines the downward direction for the user more accurately than the first downward direction determination method. can do. This is because, based on ergonomics, the tip of the index finger corresponding to the moving contact point is mainly the thumb (one finger holding the input device) and the middle finger (the other finger holding the input device) with the palm at the top. ) ”(Based on the one whose angle is smaller than 180 degrees).

  For example, even if the touch module 1 is configured by a curve along the contact detection area of the input device 100, the contact detection unit 11 converts the contact position of the user's finger or the like onto a plane. be able to. The input device 100 according to the present embodiment can detect the accurate operation direction of the user from the positional relationship (for example, the vector direction) of the contact points arranged on the plane in this way. Further, when the touch module 1 is configured by a curve along the contact detection area of the input device 100, the contact detection unit 11 may detect the positional relationship between the contact points in three dimensions. Well, the method for detecting the contact position is not particularly limited.

  In step S804, for example, fixed contact points corresponding to the thumb, middle finger, and palm are determined and stored in a storage unit (not shown), so that when the thumb is tapped, the left click is performed and the middle finger is tapped. In this case, the output unit 16 may output the information to the information processing apparatus 200 on the assumption that the right click has been performed.

  Note that the operation direction for the user determined by the direction determination unit 13 is stored in a storage unit (not shown), so that the operation direction for the user can be determined even if the index finger trajectory enters the area BCD in FIG. It can be accurately detected and confirmed.

  According to the present embodiment, even if the user grasps the input device from any direction, the input device can accurately detect the operation direction for the user and realize the operation desired by the user. That is, since the user does not need to consider the direction in which the input device is gripped, the operability of the user can be improved.

  Note that a program for the CPU to execute the processing shown in the flowcharts of the respective drawings constitutes a program according to the present invention. As a computer-readable recording medium for recording the program, a semiconductor storage unit, an optical and / or magnetic storage unit, or the like can be used. By using such a program and a recording medium in a system having a configuration different from the above-described embodiments and causing the CPU of the system to execute the program, substantially the same effect as the present invention can be obtained. .
