Abstract

<P>PROBLEM TO BE SOLVED: To prevent any malfunction when the touch position of the finger of a personally identified operator(or user) to a touch panel is isolated from the validity region of a touch UI. <P>SOLUTION: Even when an actual touch position is isolated from a touch validity region, when the touch UI control unit of an input device determines that a touch correction value under the consideration of the size of the finger of a user is within a virtual correction touch UI coordinate range showing a value integrated with the touch validity region (S9: yes), it makes touch validity determination to determine that the position touched by the user indicates that the validity region of a touch UI4 is actually touched, and inputs information assigned by the touch UI4 at the position touched by the user (S10). Thus, it is possible to solve the personal difference of operability due to the size of the finger just like it is determined that the position is not touched although it is touched even when it is determined that the touch position is isolated from the validity region of the touch UI4 when not performing correction. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to an input method and an input device, and more particularly to an input method and an input device using a touch panel.

  Input devices using touch panels are widely used. The touch panel generally includes a display screen and a sensor that detects a display position touched by a finger among display positions of a plurality of icons displayed on the display screen. In the input device using the touch panel, input information corresponding to the icon displayed at the display position is output to the processing unit according to the display position detected by the sensor.

  In an input device using this touch panel, a detection range of a sensor that detects a display position touched with a finger is predetermined. The detection range of the sensor is determined according to the size of the device on which the input device is mounted. For example, when the device is a small device such as a mobile phone, the detection range is limited to a considerably small range. .

  On the other hand, the size of the user's finger touching the display screen of the touch panel varies depending on the individual. For this reason, there is a possibility that a user with a large finger who exceeds the detection range of the sensor uses the touch panel. When the vicinity of the icon displayed on the display screen with such a large finger is touched, the finger touches not only the detection range of the sensor of the desired icon but also the detection range of the sensor of the adjacent icon. In this case, the input device does not know which display position the user touched, and malfunctions.

  Therefore, an input device that solves this problem has been proposed (see, for example, Patent Documents 1 to 4). In Patent Document 1, when the size of a finger is input by touching the touch panel, the control device sets an inputable range corresponding to the input finger size and displays the inputable range on the display. An input device configured to do so is disclosed.

  Further, in Patent Document 2, when an operator touches a finger on the touch panel, the size of the finger is measured by the measurement unit, and an input item (icon) having a size corresponding to the measured finger size is displayed on the display unit. An input device is disclosed. Similarly to Patent Document 2, Patent Document 3 discloses an input device that detects a finger size and displays an icon with a display size corresponding to the detected finger size.

  Further, Patent Document 4 detects a region of a finger touched by a touch panel, compares the detected region with information of a plurality of icon sizes stored in advance in a storage unit, and determines the plurality of icon sizes. An input device is disclosed that selects information on an icon size having an area closest to a detected area and displays an icon with the icon size.

  However, each of the input devices described in Patent Documents 1 to 4 described above is measurement information obtained by measuring the finger size input information input by the operator (or user) or the size of the finger touching the touch panel. The display size of the icon and the input range are only changed based on the display size of the icon, and even if the finger size is within the display size of one icon, If it is off, it cannot be determined that the user is touching. In addition, none of the input devices described in Patent Documents 1 to 4 performs personal authentication of the operator (or user).

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of an embodiment of an input device according to the present invention, and FIG. 2 is a block diagram of an embodiment of the input device according to the present invention. As shown in FIG. 1, the input device 1 of the present embodiment has a fingerprint authentication device 2 and a display unit 3 arranged at different positions. The display unit 3 displays a plurality of touch user interfaces (touch UI) 4 corresponding to icons that are touchable areas, and the position coordinates of the touch UI on the display screen touched with a finger among the plurality of touch UIs 4. It is comprised with the touchscreen device which consists of a sensor which detects and outputs. The sensor is a known configuration that detects the touch position and outputs the touch position coordinates when an operator (or user) finger touches the touch UI 4 on the display screen of the display unit 3. The input device 1 inputs information corresponding to the touch UI 4 touched by the finger.

  Next, the configuration of the input device 1 of the present embodiment will be described with reference to the block diagram of FIG. As shown in FIG. 2, the input device 1 according to the present embodiment includes a hardware (HW) unit 10 and a software (SW) unit 20. The HW unit 10 includes the fingerprint authentication device 2 illustrated in FIG. 1, the touch panel device 11 that configures the display unit 3 illustrated in FIG. 1, a memory device 12, and a central processing unit (CPU) 13.

  The SW unit 20 includes a touch panel control unit 21, a fingerprint authentication control unit 22, and a touch UI control unit 23. The touch panel control unit 21 receives position information and device state information of the touch UI 4 detected by the touch panel device 11 via the CPU 13. The touch panel control unit 21 also reads the touch correction information stored in the memory device 12 via the CPU 13.

  The fingerprint authentication control unit 22 performs fingerprint acquisition and finger size measurement under the control of the fingerprint authentication device 2, and stores the fingerprint and finger size in the memory device 12. The touch UI control unit 23 displays the touch UI 4 on the display unit 3 and controls the touch UI 4 based on touch information notified from the touch panel control unit 21.

  Next, the operation of the first embodiment of the present invention will be described with reference to the flowchart of FIG. First, when the user uses the input device 4 for the first time, the user touches the fingerprint authentication device 2 with an arbitrary finger to acquire the fingerprint of the finger and the size of the finger (step S1). In step S1, the fingerprint authentication control unit 22 analyzes and acquires the fingerprint of the finger touched by the fingerprint authentication device 2 by a known method, and also measures and acquires the size of the touched finger.

  Subsequently, the fingerprint authentication control unit 22 checks whether or not the fingerprint and the measured finger size information are already registered in the memory device 12 (step S2). If not registered, the fingerprint acquired in step S1 and the measured finger size information are registered in the memory device 12, the finger size is read (step S3), and the touch panel control unit 21 is notified accordingly.

  On the other hand, when the fingerprint and the size of the finger are already registered, the fingerprint authentication control unit 22 collates the fingerprint registered in the memory device 12 with the fingerprint acquired in step S1, and matches the collation. Is determined (step S4). If the collation matches, it is determined that the authorized user registered in the input device 1 uses the input device 1, and the information on the finger size of the user registered in the memory device 12 is read (step S5). ), And notifies the touch panel control unit 21 to that effect. Note that if the verification does not match, the process ends.

  When the touch panel control unit 21 receives the notification of the finger size information after the process of step S3 or S5, the touch panel control unit 21 calculates a touch correction value (step S6). This touch correction value is, for example, a value for converting a coordinate value notified when the user touches the touch UI 4 into an optimal coordinate value according to the size of the user's finger.

  Thereafter, the user touches the touch UI 4 corresponding to the information to be input among the plurality of touch UIs 4 displayed on the display unit 3 (step S7). Then, the touch panel device 11 configuring the display unit 3 notifies the touch panel control unit 21 of coordinate information of the position of the touch UI 4 touched by the user. The touch panel control unit 21 notifies the touch UI control unit 23 of the notified coordinate information of the touch position and the touch correction value calculated according to the size of the finger in step S6 (step S8).

  Here, the touch UI control unit 23 holds the size (effective area) of the touch UI 4 in advance. The touch UI control unit 23 is a virtual corrected touch UI coordinate range in which the coordinate information of the position actually touched by the user combines the effective area of the touch UI 4 and the touch correction area calculated based on the touch correction value. It is determined whether or not it is included in the (touch determination effective area) (step S8). Even if the coordinates of the position touched by the user are outside the effective area of the touch UI, if the finger is large, a part of the touch UI 4 is substantially touched. The virtual correction touch UI coordinate range described above indicates a substantial touch effective area of the touch UI4.

  Accordingly, even if the actual touch position is out of the effective touch area, the touch UI control unit 23 is a virtual indicating a value obtained by combining the touch correction value considering the size of the user's finger with the effective touch area. If it is determined that it is within the corrected touch UI coordinate range (touch determination effective area) (Yes in step S9), the position touched by the user substantially touches the effective area of the touch UI4. The touch validity determination indicating that the user has touched is performed, and information assigned by the touch UI 4 at the position touched by the user is input (step S10).

  On the other hand, when the touch UI control unit 23 determines that the coordinate information of the position of the touch UI 4 actually touched by the user is not included in the virtual corrected touch UI coordinate range (touch determination effective region) ( (No in step S9), a touch invalidity determination is made to indicate that the notified position touched by the user has not touched the valid area of the touch UI4 (step S11), and information input when the touch UI4 is touched is performed. The process ends without performing it.

  Thus, according to the present embodiment, the coordinates of the position touched by the user are within the virtual corrected touch UI coordinate range (touch determination effective area) corresponding to the size of the user's finger authenticated by fingerprint authentication. When it is determined that the touch is valid, it is determined that the touch UI 4 is not touched even if it is determined that the touch UI 4 is out of the effective area. Individual differences in operability due to the size of the finger can be eliminated.

  Further, according to the present embodiment, the virtual corrected touch UI coordinate range (touch determination effective area) is a value calculated based on the effective area of one touch UI4, and is adjacent to the effective area of one touch UI4. The area is smaller than the sum area with the area where no touch UI exists between the two touch UI4. For this reason, even if the coordinates of the touch position deviate from the effective areas of the two adjacent touch UIs 4, when the touch is very close to the effective area of one of the touch UIs 4, the virtual correction touch Since the UI coordinate range (touch determination effective area) includes the effective area of one touch UI4 and does not include the effective area of the other touch UI4, the touch panel control unit 21 touches only one touch UI4. It is possible to prevent malfunction due to erroneous determination that the two adjacent touch UIs 4 are simultaneously touched.

  Next, the operation of the second embodiment of the present invention will be described with reference to the flowchart of FIG. In the figure, the same processing steps as those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted. Similar to the first embodiment, this embodiment is common in that the operation of the input device having the configuration shown in FIGS. 1 and 2 is different, but the touch correction value calculation process is different.

  That is, in this embodiment, the fingerprint authentication control unit 22 notifies the touch panel control unit 21 that the fingerprint and the finger size have not been registered, and the touch correction value is calculated based on the finger size acquired in step S1. Calculate (step S21). Then, the fingerprint authentication control unit 22 registers the acquired fingerprint and finger size in the memory device 12 together with the touch correction value calculated by the touch panel control unit 21, and reads the touch correction value (step S22).

  On the other hand, the fingerprint authentication control unit 22 determines that the fingerprint and the size of the finger have already been registered in the memory device (yes in step S2), and if the fingerprint collation further matches (yes in step S3), step S22. The touch correction value registered in the memory device 12 is read from the memory device 12 (step S23). Thereafter, the same operation as in the first embodiment after step S7 is performed.

  As described above, in this embodiment, the touch correction value calculated when the first touch UI 4 is touched is registered in the memory device 12, and thus the touch correction value calculation operation when touching the touch UI 4 for the second time and thereafter is performed. Can be eliminated and the processing speed can be increased.

  In the above embodiment, it is determined whether both the fingerprint and the finger size have been registered. However, it may be determined whether only one of them has been registered.

It is a schematic block diagram of one Embodiment of the input device of this invention. It is a block diagram of one embodiment of the input device of the present invention. It is a flowchart for description of the first embodiment of the input method of the present invention. It is a flowchart for description of 2nd Embodiment of the input method of this invention.
