Abstract

PROBLEM TO BE SOLVED: To provide an operation display device capable of reducing erroneous determination of an operation received from a user.SOLUTION: An index value (for instance, travel distance from a touch to a release) to determine a type of received operation is obtained from detection information of a touch panel part. If the index value is within a select determination region, it is determined that a select operation is received, and if the index value is within a flick determination region, it is determined that a flick operation is received. If the index value is within a determination difficult region between the select determination region and the flick determination region, a user is notified of the difficulty to determine the type of the operation. Thereafter, the type of the operation is designated by the user or the operation is reentered.

Description

  The present invention relates to an operation display device that receives a plurality of types of operations on a touch panel.

  In an operation display device using a touch panel that detects a position touched by a user's fingertip or pen, in addition to a selection operation for selecting an operation button, a flick operation or dragging that moves while the fingertip or pen is touched. Various operations such as operations can be received.

  In such a touch panel type operation display device, various techniques have been proposed for more accurately determining the type of operation received from the user.

  For example, in consideration of the possibility of subtle deviations in the operation position during the selection operation, the area around the operated position is set as the detection area, and the average value of the operation positions in this detection area is determined as the final operation. There is a technique for determining the position (see Patent Document 1).

  There is also a technique for determining whether the operation is a selection operation or a gesture operation such as a flick operation according to the amount of movement from the touch position to the untouch position (see Patent Document 2).

  The pressing force during the operation such as the selection operation and the flick operation, the moving distance and moving speed after the touch, etc. vary depending on the operator. It is difficult to identify an operation without erroneous determination.

  For example, when the finger is moved away from the touch panel in the selection operation, the finger may be erroneously determined as a flick operation if the finger moves in any of the up, down, left, and right directions. In addition, since a resistive touch panel does not recognize that a finger is touching the touch panel unless there is an appropriate pressure, a flick operation performed with a light pressing force may be erroneously determined as a selection operation.

  If the user's operation is erroneously determined in this way, the process corresponding to the operation not intended by the user is executed. Therefore, after canceling the process, the user erroneously determines the originally intended operation. It was inconvenient that you had to do it carefully.

  The present invention is intended to solve the above problem, and an object of the present invention is to provide an operation display device that can suppress erroneous determination of an operation received from a user.

The network communication unit 19, the authentication unit 21, and the operation display unit 30 are connected.

  The CPU 11 is based on an OS (Operating System) program, and executes middleware, application programs, and the like. The CPU 11 also functions to control the operation of the operation display unit 30 as the operation display device according to the present invention.

  Various programs are stored in the ROM 12, and each function of the multifunction machine 10 is realized by the CPU 11 executing various processes according to these programs.

  The RAM 13 is used as a work memory for temporarily storing various data when the CPU 11 executes processing based on a program, an image memory for storing image data, and the like.

  The image reading unit 14 functions to optically read a document and acquire image data. The image reading unit 14 sequentially, for example, a light source that irradiates light on a document, a line image sensor that receives the reflected light and reads the document for one line in the width direction, and sequentially reads the reading position in line units in the length direction of the document. An optical path composed of a moving unit for moving, a lens, a mirror, and the like for guiding reflected light from the document to the line image sensor to form an image, and a conversion unit for converting an analog image signal output from the line image sensor into digital image data And so on.

  The printer unit 15 functions to form an image corresponding to the image data on a recording sheet. Here, it has a recording paper transport device, a photosensitive drum, a charging device, a laser unit, a developing device, a transfer separation device, a cleaning device, and a fixing device, and forms an image by an electrophotographic process. It is configured as a so-called laser printer engine unit. Other methods may be used for image formation.

  The image processing unit 16 performs processing such as image enlargement / reduction, rotation, rasterization processing for converting print data into image data, image data compression / decompression processing, and the like.

  The nonvolatile memory 17 is a memory (flash memory) whose stored contents are not destroyed even when the power is turned off, and is used for storing various setting information. The non-volatile memory 17 stores authentication information for user authentication and information of a determination area, which will be described later, used for determining the type of operation for each user.

  The facsimile communication unit 18 performs a function of transmitting / receiving image data to / from an external device having a facsimile function through a public line.

  The network communication unit 19 performs a function of communicating data with a terminal device or other external devices through a network such as a LAN (Local Area Network).

  The authentication unit 21 performs a user authentication function that identifies a user who operates the multifunction machine 10. The authentication method may be any personal authentication method such as user authentication using a token device such as an IC card or user authentication using biometric information such as a fingerprint.

  The operation display unit 30 includes a display unit 31 and an operation unit 32. Among these, the operation unit 32 includes a switch unit 33 such as a start button and a touch panel unit 34. The display unit 31 is composed of a liquid crystal display (LCD) and the like, and has a function of displaying various operation screens, setting screens, and the like.

  The touch panel unit 34 is provided on the display surface of the display unit 31. Here, a resistive film type touch panel is used. An electrostatic capacitance method or other methods may be used. The touch panel unit 34 detects that the display surface (actually it is a touch panel on the display surface but is expressed as a display surface) with a touch pen or a fingertip, and detects the pressed position, and the detection result. Is output. The position is indicated by coordinate information with a predetermined position on the display surface of the display unit 31 as the origin.

  The action of touching the display surface with a fingertip or the like is referred to as touch, and the action of moving the fingertip or the like away from the display surface is referred to as release. In the following description, it is assumed that the fingertip touches the display surface.

  The operation display unit 30 of the multifunction machine 10 accepts a plurality of types of operations such as a selection operation, a flick operation, and a drag operation as operations on the touch panel unit 34.

  The selection operation is an operation of releasing from the display surface without touching or moving the fingertip from the touched position after touching the display surface with the fingertip. The flick operation is an operation of touching the display surface with a fingertip or the like and then moving the finger so as to pay off and releasing from the display surface. The drag operation is an operation in which, after touching the display surface with a fingertip or the like, the fingertip is moved to a target location while being touched, and the fingertip is released from the display surface with the movement substantially stopped.

  When receiving an operation from the user, the operation display unit 30 of the multifunction machine 10 determines the type of operation. The types of operations to be determined include the select operation, flick operation, and drag operation described above. Also, when an operation that tends to cause a discrepancy between the type of operation determined by the device and the type of operation intended by the user, such as a select operation or a flick operation, is received, an operation that is difficult to determine The received information is displayed, and the type of operation is not unilaterally determined on the device side.

  A method for determining the type of operation will be described.

(First method)
In the first method, the type of operation is determined using the movement distance of the finger from touch to release as an index. FIG. 2 exemplifies each determination area when a selection operation and a flick operation are determined by the first method. The horizontal axis of the chart in FIG. 2 indicates the moving distance from touch to release.

  A selection determination area 41 for determining that the movement distance is less than the first threshold L1 is a selection operation, a flick determination area 42 for determining that a movement distance is the second threshold L2 or more is a flick operation, and a movement distance is the first threshold L1 or more. In addition, a region less than the second threshold L2 (a hatched region in the figure) is set as a difficult-to-determine region 43 where it is difficult to determine a selection operation and a flick operation. That is, the region between the select determination region 41 and the flick determination region 42 is a difficult determination region 43.

  The movement distance is obtained as a linear distance connecting the coordinates of the position where the touch is detected and the coordinates of the position where the release is detected. Note that the position of the finger from the touch to the release may be tracked, and the length of the trajectory may be obtained as the movement distance. Further, the movement distance may be obtained as a distance in the scroll display direction. For example, for the operation received in the display area that can be scrolled in the vertical direction, the movement distance in the vertical component is obtained.

(Second method)
In the second method, the type of operation is determined by using as an index a combination of two elements of a finger movement distance from touch to release and a time from touch to release (referred to as ON time). The moving distance is obtained by the same method as the first method. FIG. 3 exemplifies each determination area when a selection operation, a long-press selection operation, a flick operation, and a drag operation are determined by the second method. The horizontal axis of the chart in FIG. 3 indicates the movement distance, and the vertical axis indicates the ON time.

  An area where the movement distance is less than the first threshold L1 and the ON time is T1 or more and less than T2 is determined as the selection determination area 41, and an area where the movement distance is less than the first threshold L1 and the ON time is T2 or more is determined as a long press selection operation. This is a long press select determination area 44.

  A region where the moving distance is equal to or greater than the second threshold L2 and the ON time is equal to or greater than T1 and less than T3 is a flick determination region 42, and a region where the movement distance is equal to or greater than the second threshold L2 and the ON time is equal to or greater than T4 It has become.

  The type of operation cannot be clearly specified for areas other than the above four determination areas (select determination area 41, long press selection determination area 44, flick determination area 42, drag determination area 45). It is set in the difficult determination area 43.

  In the example of FIG. 3, the determination difficulty region 43 is not set between the selection determination region 41 and the long press selection determination region 44, but it is assumed that the sense of time for the long press differs depending on the user. May determine a difficult-to-determine area 43 between the select determination area 41 and the long-press selection determination area 44. The range of each area can be arbitrarily changed by, for example, an administrator.

  FIG. 4 shows an example of an operation screen displayed on the display unit 31 of the operation display unit 30 by the multifunction machine 10. This screen is a file selection screen 50 for selecting a file to be processed. A list display area 51 is provided on the file selection screen 50. The list display area 51 displays a list of file names of selection candidates.

  The number of file names that can be displayed in the list display area 51 is limited, and when the number of selection candidates is larger than this number, the list displayed in the list display area 51 can be scrolled and displayed. Become.

  In a scrollable state, a scroll bar 52 is displayed at the right end of the list display area 51. A knob 53 is displayed in the middle of the scroll bar 52, and arrows 54 are displayed at both ends. The knob 53 represents the ratio and position of the portion displayed in the list display area 51 in the entire list. An arrow 54 is an operation button that is controlled so that when the user clicks here, the list is scrolled by a certain amount in the direction indicated by the arrow.

  As a method of scrolling the list displayed in the list display area 51, there is a method of performing a flick operation in the list display area 51 in addition to a method of operating the knob 53 or the arrow 54 of the scroll bar 52.

  In the list display area 51 of the file selection screen 50 of FIG. 4, the displayed list can be scrolled up and down. The user can scroll the list in the list display area 51 by flicking up or down.

  Further, by performing a select operation on the display location of any file name in the list displayed in the list display area 51, the file with that file name is selected as a processing target.

  FIG. 5 shows a state where a flick operation is performed in the list display area 51 of the file selection screen 50 shown in FIG. FIG. 5 shows an example in which a flick operation is performed from the bottom to the top.

  Next, operation examples 1 to 3 in the case where an operation that makes it difficult to determine the operation type in the list display area 51 of the file selection screen 50 shown in FIGS. 4 and 5 will be described. The operation whose operation type is difficult to determine is an operation in which the value of a predetermined index for determining the operation type enters the determination difficult region 43.

  Here, the types of operations that can be received in the list display area 51 are only flick operations and select operations. In addition, it is assumed that user authentication is performed by the authentication unit 21 at the time of starting use of the multifunction machine 10 and the user to be operated is specified. The operation display unit 30 of the multifunction machine 10 holds the information of the area shown in FIGS. 2 and 3 in the nonvolatile memory 17 for each user, and is stored in association with the user authenticated by the authentication unit 21. The type of operation is determined based on the information of the area that is present.

<Operation example 1>
The fact that the type of operation could not be determined is displayed, and selection of the type of operation is accepted from the user.

  FIG. 6 shows a display example in the case of the first operation example. When the operation display unit 30 of the MFP 10 receives an operation that is difficult to determine whether the operation is a flick operation or a select operation in the list display area 51 of the file selection screen 50, the operation selection window 61 is displayed in the file selection screen 50. Pop-up display.

  The operation selection window 61 displays a message 62 indicating that the type of operation could not be determined and requesting the user to press the selection button corresponding to the type of operation intended by the user. The operation selection window 61 displays a selection button for receiving a selection of an operation type from the user. Here, a select button 63 corresponding to the select operation and a flick button 64 corresponding to the flick operation are displayed.

  When the user presses the selection button 63 or 64 corresponding to the operation performed by the user, the previous operation for which the type of operation could not be determined was the operation corresponding to the pressed selection button 63 or 64. The processing corresponding to the operation is performed. For example, when the select button 63 is selected, the file having the file name at the operation position is set as the processing target. When the flick button 64 is selected, the list is scrolled.

  Further, the information of the area stored in the nonvolatile memory 17 is changed in association with the authenticated user. That is, the setting of each area is changed so that the operation whose operation type could not be determined earlier is determined as the operation of the type specified by the selection buttons 63 and 64.

  For example, in the setting state of the region as shown in FIG. 7A, the index value (movement distance in this example) in the operation whose operation type could not be determined is M, and the flick button 64 in the operation selection window 61 is displayed. Is selected, the range of each region is changed so that the index value M is included in the flick determination region, as shown in FIG. At this time, it is desirable to change the range of each region so that a certain margin is generated between the index value M and the boundary between the flick determination region 42 and the difficult determination region 43. In this example, the boundary between the select determination area 41 and the difficult determination area 43 is also moved, but this boundary may not be moved.

<Operation example 2>
A message indicating that the type of operation could not be determined is displayed, and an operation learning mode is entered.

  FIG. 8 shows a display example in the case of the operation example 2. When the multifunction device 10 receives an operation that is difficult to determine whether the operation is a flick operation or a select operation in the list display area 51 of the file selection screen 50, the MFP 10 temporarily stores an index value related to the operation and also stores the index value in the file selection screen 50. The operation learning window 71 is pop-up displayed.

  The operation learning window 71 displays a message 72 indicating that the type of operation could not be determined and entering the operation learning mode. The operation learning window 71 also displays an operation input field 73 for accepting an operation to be learned and a message 74 that requests the user to perform a specified type of operation in the operation input field 73.

  The user performs the specified type of operation in the operation input field 73 and presses the OK button 75. The CPU 11 of the multifunction machine 10 obtains an index value of the operation from the operation received in the operation input field 73. Then, the information of the area stored in the nonvolatile memory 17 is changed in association with the authenticated user so that the index value enters the determination area for the designated type of operation.

  Furthermore, the index value corresponding to the operation when the type of operation could not be determined, which was temporarily stored earlier, is read out, and the area to which the index value belongs is re-determined based on the changed area. Then, processing corresponding to the operation indicated by the determination result is performed.

  In the example of FIG. 8, a flick operation is specified (specified) as an operation to be learned, and a flick operation is accepted from the user in the operation input field 73, and an index value (for example, a movement distance) corresponding to the flick operation is set. Then, the area corresponding to the user is changed so that the index value enters the flick determination area 42.

  Note that the learning operation is not limited to the flick operation, but may be both a select operation and a flick operation. Each type of operation may be specified and received from the user. For example, a message instructing to perform a flick operation for the first time and a select operation for the second time may be displayed, and each operation may be accepted.

<Operation example 3>
Notify that the type of operation could not be determined and that the operation is to be performed again, and receive a re-operation.

  FIG. 9 shows a display example in the case of the operation example 3. When the multifunction device 10 receives an operation that is difficult to determine whether it is a flick operation or a select operation in the list display area 51 of the file selection screen 50, the multifunction device 10 pops up a re-operation request window 81 in the file selection screen 50.

  The re-operation request window 81 displays a message 82 and an OK button 83 requesting that the operation type cannot be determined, and to perform the operation again.

  When the OK button 83 is pressed, the multifunction machine 10 returns to the state before receiving the operation that is difficult to determine, and accepts the operation again.

  FIG. 10 shows the flow of processing corresponding to the operation example 1 or the operation example 2, which is an operation of the multifunction peripheral 10 related to the operation determination. The multifunction device 10 first performs user authentication at the start of use by the user to identify the user (step S101). Information on the area stored in the nonvolatile memory 17 in association with the user specified by the user authentication is read and loaded into a predetermined memory area (step S102). During operation, information on the area stored in this memory area is referred to.

  Thereafter, when a touch with a user's finger or the like is detected on the touch panel unit 34 of the operation display unit 30 (step S103; Yes), the coordinates of the touched position output as a detection result from the touch panel unit 34 are temporarily stored. (Step S104). Thereafter, when a release is detected (step S105; Yes), the coordinates of the released position output as a detection result from the touch panel unit 34 are detected (step S106).

  The movement distance of the finger from the touch to the release based on the coordinates of the touched position and the released position is obtained as an index value for determining the type of operation (step S107). Then, with reference to the information of the area loaded in step S102, the area including this movement distance is determined (step S108). When the movement distance obtained in step S106 is included in the flick determination area 42 (step S108; flick area), a process corresponding to the flick operation is performed (step S109), and this process is terminated.

  When the movement distance obtained in step S106 is included in the selection determination area 41 (step S108; selection area), a process corresponding to the selection operation is performed (step S110), and this process ends.

  When the movement distance obtained in step S106 is included in the difficult-to-determine region 43 (step S108; difficult-to-determine region), the operation selection window 61 or the operation learning window 71 shown in the operation example 1 or the operation example 2 is displayed. The fact that the operation received this time was difficult to determine is notified (step S111). Then, the operation type designation is received by the select button 63 or the flick button 64 as shown in the operation example 1, or the learning mode is entered and the operation is received as shown in the operation example 2, so that Update information. Here, both the information on the area referred to during the operation and the information on the area corresponding to the user stored in the nonvolatile memory 17 are updated. Then, the type of operation that has been difficult to determine is determined, a process corresponding to the operation is performed (step S112), and this process ends.

  In addition, when receiving the next operation further, after steps S109, S110, and S112, the process returns to step S103 to continue the process.

  FIG. 11 shows a flow of processing corresponding to the operation example 3, which is an operation of the multifunction peripheral 10 related to the determination of the operation. The same steps as those in FIG. 10 are denoted by the same step numbers, and description thereof will be omitted as appropriate.

  The processing from step S101 to step S110 is the same as that in FIG. When the movement distance obtained in step S106 is included in the difficult-to-determine area 43 (step S108; difficult-to-determine area), the re-operation request window 81 shown in the operation example 3 is displayed, and the operation received this time is difficult to determine. A notification is made (step S121). And it returns to step S103 and continues a process. Thereby, the user performs a re-operation.

  As described above, a predetermined index value for determining the type of operation received by the touch panel unit 34 is obtained from the detection information of the touch panel unit 34. If the index value is in the selection determination area 41, the selection operation is received. If the index value is in the flick determination area 42, it is determined that a flick operation has been received. If the index value is in the determination difficulty area 43 between the select determination area 41 and the flick determination area 42, the type of operation is determined. Is displayed on the display unit 31 to notify the user, so that the user can learn what operation is confusing and can prompt the user to perform an accurate operation.

  In addition, when it is difficult to make a decision, the user can specify the type of operation or learn the characteristics of the user's operation. Therefore, the area can be corrected to reflect the characteristics of the user's operation. Thereafter, the type of operation can be determined as intended by the user.

  In addition, since the determination is made for each user using the area corresponding to the user and the area is updated, the type of operation received from each user can be accurately determined even if the operation habits vary for each user. Can be determined.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  In the embodiment, the operation display unit 30 provided in the multifunction machine 10 has been described as an example. However, the operation display device according to the present invention may be provided in another device, and may be provided separately from the device main body. It may be configured as an operation display device.

  In the embodiment, the case where the movement distance or the combination of the movement distance and the ON time is used as an index for determining the type of operation is shown, but the index is not limited to this. For example, the type of operation may be determined using as an index a combination of the movement distance, the acceleration of movement, the ON pressure, and the like.

  In the embodiment, the selection operation, the flick operation, and the like are operations to be determined, but the operation is not limited to these as long as the operation is performed by the user on the touch panel unit. For example, the first operation may be an operation for drawing a circle, and the second operation may be an operation for drawing a rectangle. In this case, a predetermined index for identifying these is set (an index in which the presence or absence of a corner-like portion or the linearity of regulation is quantified), and an area, a square, or the like determined to be a circle with respect to the value of this index It is also possible to set an area for determining that the area is difficult and a difficult-to-determine area between them.
