Description

  The present invention relates to an object operation device and an object operation control program, and in particular, an object operation device including a touch panel having a touch sensor that can identify two types of instruction means on a display surface, and an object that controls an operation on an object being handwritten. It relates to an operation control program.

  In recent years, with the widespread use of portable terminals such as tablet terminals and portable computer devices equipped with a touch panel, there are increasing opportunities for handwriting input of objects such as characters and figures. In addition, electronic conferences in which each user inputs an object by hand using his / her portable terminal, displays the object on a shared screen, and proceeds with the conference while viewing the object displayed on the shared screen are also held. It is coming. In such a system, it may be necessary to divide, combine, specify a range, partially erase, enlarge / reduce, change color / thickness / line type, etc. for an object input by handwriting. Various methods have been proposed.

  For example, in Patent Document 1 below, regarding a mode-based graphical user interface for a touch-sensitive input device, a user interface mode is determined based on touch characteristics, and a GUI (Graphical User Interface) element is displayed. Or displaying a virtual scroll wheel for a scroll gesture.

  Further, in Patent Document 2 below, a finger detection unit that is provided on a display screen and detects a coordinate touched by a finger / hand and outputs a first detection signal; and a touch detection unit that is provided on the display screen and touched with a pen. Pen detection means for detecting the detected coordinates and outputting a second detection signal; if the pen is used, the pointing is extracted from the second detection signal, a pointing instruction is issued, and the second There is disclosed a coordinate input device including signal processing means for extracting only a predetermined gesture from one detection signal and issuing a corresponding command.

Special table 2008-508600 gazette JP 2011-186550 A

  Usually, functions such as screen scrolling and object movement are pre-assigned to finger touch panel operations, so functions specific to the object being handwritten (such as object division, combination, range specification, and partial deletion) , Enlargement / reduction, change of color / thickness / line type, etc.) cannot be assigned. For this reason, as in Patent Document 1, a menu screen is displayed, and selecting a function on the menu screen results in a UI that switches a function to be executed on a handwritten input object.

  However, since operations are frequently performed on objects during handwriting input, if a complicated operation such as menu selection is performed during handwriting input, thinking is interrupted, and handwriting input is smoothly performed in scenes such as idea generation. It becomes impossible to do. Moreover, since it is difficult to perform complicated operations such as menu selection in parallel with handwriting input, writing cannot be caught up in situations such as leaving the contents of another person's story.

  For example, in an application in which an object such as a character or a figure is input by handwriting and the object input by handwriting can be freely moved, it is important that the handwritten object is divided into units as intended by the user. In the existing technology, an object can be automatically divided with a certain degree of accuracy by a temporal or spatial distance between strokes or character recognition. However, in the existing technology, since the object is not necessarily divided as intended by the user, it is necessary to correct the automatically divided object after handwriting input. In this correction, since a complicated operation such as menu selection must be performed, there arises a problem that thoughts are shredded and writing cannot be caught up.

  In order to cope with such a problem, Japanese Patent Laid-Open No. 2004-228867 can identify handwriting input by a pen device and finger / hand operation and extract only a predetermined gesture from the first detection signal by the finger / hand. A configuration for issuing commands is disclosed. However, in Patent Document 2, a function corresponding to an operation with a finger / hand cannot be switched depending on whether or not handwriting is being input. For this reason, a finger / hand operation must be newly defined for an object being handwritten, and the operation becomes difficult due to an increase in the types of operations.

  The present invention has been made in view of the above problems, and its main purpose is to switch a function corresponding to an operation with a finger or the like according to whether or not a handwriting input by a pen device or the like is being performed, and an appropriate object It is an object to provide an object operation device and an object operation control program that can be formed.

  An apparatus according to one aspect of the present invention includes a touch sensor that can identify a touch by two types of instruction means, a display unit that includes the touch sensor on a display surface, and displays an object handwritten by one of the instruction means. Control for recognizing an operation by the other instruction means as a specific operation on the object being handwritten and executing a function associated with the specific operation when handwriting input by the one instruction means is being performed And a section.

  In addition, a program according to one aspect of the present invention includes a touch sensor that can identify a touch by two types of instruction means, a display that includes the touch sensor on a display surface, and displays an object handwritten by the one instruction means. An object operation control program that operates on a device that controls the unit, and when the handwriting input by the one instruction unit is being performed on the device, the operation by the other instruction unit is performed on the object being handwritten A second process for recognizing the specific operation and executing a function associated with the specific operation is performed.

  According to the object operation device and the object operation control program of the present invention, it is possible to perform appropriate object formation by switching the function corresponding to the operation with a finger or the like during handwriting input by a pen device or the like.

  The reason is that, in an object operation device including a touch panel that can identify a touch by two types of instruction means (for example, a pen device and a finger), the control unit is performing handwriting input by one instruction means (for example, a pen device). In this case, the operation by the other instruction means (for example, a finger) is recognized as a specific operation for the object being handwritten and control is performed to execute a function associated with the specific operation.

  As described above, in the present invention, since a different function is associated with a finger operation during handwriting input and after handwriting input, a desired function is executed on an object being handwritten with a simple finger operation. be able to. As a result, thoughts are not interrupted by complicated operations and can be operated in parallel (or in a sufficiently short time) with handwriting input, so that writing is not delayed and appropriate object formation is achieved. It can be carried out.

It is a figure explaining the conventional operation method of an object. It is a figure explaining an example of the operation method of the object which concerns on one Embodiment of this invention. It is a figure which shows typically the structural example of the object operating device which concerns on one Example of this invention. It is a block diagram which shows the structure of the object operation apparatus which concerns on one Example of this invention. It is an example of the function matching information which the object operating device which concerns on one Example of this invention refers. It is a flowchart figure which shows the process (new object creation process) of the object operating device concerning one Example of this invention. It is a flowchart figure which shows the process (judgment process during handwriting input) of the object operating device which concerns on one Example of this invention. It is a flowchart figure which shows the whole process of the object operating device which concerns on one Example of this invention.

  As shown in the background art, since predetermined functions such as screen scrolling and object movement are usually assigned to the operation of the touch panel with a finger, functions specific to the object being handwritten (such as object division) , Combination, range designation, partial deletion, enlargement / reduction, change of color / thickness / line type, etc.) cannot be assigned. For example, as shown in FIG. 1A, a drag operation is moved, a tap operation is selected, a long press operation is a menu display, and a pinch operation is pre-assigned such as enlargement / reduction. You cannot assign a specific function to an object.

  Therefore, when executing a function peculiar to a handwritten input object (for example, combining objects during handwriting input), as shown in FIG. Call and select a desired function (in this case, combination) in the menu screen, and specify the range of objects to be combined by dragging. However, if such a complicated operation is performed, thinking is interrupted, and it is difficult to perform such a complicated operation in parallel with handwriting input, and thus writing cannot be followed.

  Even if it is possible to distinguish between handwriting input by a pen device and operation by a finger, if the function corresponding to the finger operation cannot be switched depending on whether or not the handwriting input is being performed, handwriting input is performed separately from normal finger operation. You must define a new finger operation that indicates a function specific to the object inside. As a result, the types of finger operations increase and become complicated, and a desired function cannot be easily executed on an object being handwritten. In particular, since functions are already assigned to general finger operations, the newly defined finger operations become complicated gestures, making the user's usability worse, and processing on the device side to discriminate finger operations It becomes complicated.

  Therefore, in one embodiment of the present invention, when a user performs handwriting input with a pen device and performs an operation on an object handwritten input by finger touch input, handwriting input and handwriting input are performed for the finger operation. Different functions are associated with each other. Then, it is determined whether or not handwriting input by the pen device is being performed. When it is determined that handwriting input is being performed, the finger operation is recognized as a specific operation on the object being handwritten and is associated with the specific operation. Functions (dividing, combining, range designation, partial erasure, enlargement / reduction, change of color / thickness / line type, etc.) are executed.

  Hereinafter, specific examples will be described with reference to FIG.

  First, a rectangular frame is displayed around the object in the handwritten input. Then, as shown in FIG. 2A, the finger is moved toward the object that has been handwritten, starting from the object being handwritten. This finger operation is an operation for moving an object when handwriting input is not being performed, but is recognized as an operation for instructing the combination of objects during handwriting input, and the object being handwritten and the object that has been handwritten input are combined. Perform the function. Then, a rectangular frame surrounding the two objects is displayed so that it can be confirmed that the connection has been performed as intended by the user, and the operation is visually fed back as needed. Similarly, when two objects are touched with two fingers, it is recognized as an operation for instructing the combination of the objects.

  Further, as shown in FIG. 2B, the finger is moved across the object with respect to the object being handwritten. This operation is an operation for moving the object in the same manner as described above when not being handwritten, but is recognized as an operation for instructing the division of the object during the handwriting input, and two operations are performed with the line where the finger is moved as a boundary. Executes the function of dividing into objects. Then, in order to confirm that the division has been performed as intended by the user, a rectangular frame surrounding an object input later by handwriting is displayed, and the operation is visually fed back as needed.

  Further, as shown in FIG. 2C, the finger is reciprocated finely on the object with respect to the object being handwritten. This operation is an operation for moving the object in the same manner as described above when not being handwritten, but is recognized as an operation for instructing partial erasure of the object during handwriting input, and the object in the area where the finger is moved is erased. Perform the function. Then, a rectangular frame surrounding the object that has not been deleted is displayed so that it can be confirmed that the partial deletion has been performed as intended by the user, and the operation is visually fed back as needed.

  In this way, it is determined whether or not handwriting input by the pen device is being performed, and during handwriting input, a general finger operation such as dragging or tapping is recognized as a specific operation for the object being handwritten, thereby It is possible to easily manipulate an object during handwriting input while avoiding complicated operation.

  It is determined that handwriting input is being performed during a handwriting input by the pen device and until a predetermined time has elapsed after the handwriting input is interrupted. Then, the finger operation during handwriting input is processed as an instruction operation such as combination / division, partial erasure, and the finger operation after a predetermined time has elapsed is processed as a normal operation (drag operation or tap operation). In this way, by determining that the handwriting input is in progress until a predetermined time has elapsed as well as during the handwriting input by the pen device, there is room for considering an operation on the object input by handwriting, and appropriate object formation can be performed. . Further, when it is determined that the handwriting input is not being performed after a predetermined time has elapsed, the operation of returning to the normal operation can be omitted, and the convenience for the user can be improved.

  At this time, as shown in FIG. 2D, the elapsed time after handwriting input can be displayed in association with the object (in the lower part of the object in the figure). By displaying the elapsed time after handwriting input in this way, it is possible to avoid the inconvenience that a finger operation on an object during handwriting input is determined as a normal operation when a predetermined time elapses. Moreover, although the said predetermined time is good also as fixed time, as shown in FIG.2 (d), it can also enable it to change the state in handwriting input by finger operation. By making the handwriting input state changeable in this way, when the handwriting input state is extended, it is possible to fully consider what kind of operation is performed on the handwritten input object. When the input state is shortened, it is possible to quickly return to normal finger operation, and appropriate object formation can be performed.

  In order to describe the above-described embodiment of the present invention in more detail, an object operation device and an object operation control program according to an embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a diagram schematically illustrating a configuration example of the object operation device according to the present embodiment, and FIG. 4 is a block diagram illustrating a configuration of the object operation device. FIG. 5 is an example of the function association information according to the present embodiment, and FIGS. 6 to 8 are flowcharts illustrating processing of the object operation device according to the present embodiment.

  As shown in FIG. 3A, the object operating device 10 of the present embodiment is a portable computer device or tablet terminal provided with a touch panel, a PDA (Personal Digital Assistants), a smartphone, or the like. The object operation device 10 may be configured integrally with a display screen having a touch panel and a controller that performs object operation. As shown in FIG. The controller that performs the above may be configured separately. 3A may be a system in which a plurality of object operation devices 10 are connected via a communication network, and a system in which the object operation device 10 illustrated in FIG. 3B is connected via a communication network may be used. Also good.

  4 is a block diagram showing the configuration of the object operation device 10 in FIG. 3A. The object operation device 10 includes a control unit 11 (controller in FIG. 3B), a display unit 12, and an operation unit 13. (Display screen in FIG. 3B).

  The control unit 11 includes a CPU (Central Processing Unit) 11a, a memory such as a ROM (Read Only Memory) 11b and a RAM (Random Access Memory) 11c, an HDD (Hard Disk Drive) 11d and a communication I / F as necessary. The unit 11e is configured. The CPU 11a reads a program for controlling the operation of the object operation device 10 from the ROM 11b and the HDD 11d, and develops and executes the program on the RAM 11c. The communication I / F unit 11e is configured by a NIC (Network Interface Card), a modem, or the like, and establishes a connection with another object operation device 10 and transmits / receives objects as necessary.

  In addition, the ROM 11b and the HDD 11d store function association information for associating different functions with finger operations during handwriting input and other than during handwriting input. This function association information is configured as shown in FIG. 5, for example, and functions correspond to each finger operation (gesture) except during handwritten input and during handwritten input (noted as non-handwritten input). It is attached. For all finger operations (gestures), there is no need to change the function during handwriting input and during non-handwriting input. Further, for all finger operations (gestures), it is not necessary to associate functions with both handwritten input and non-handwritten input, and functions may be associated with only one of them. This function association will be described later.

  The control unit 11 functions as an object operation control unit. When the object operation control unit discriminates an input by a pen device such as a stylus pen (hereinafter simply referred to as a pen) and an input by a finger or hand (hereinafter referred to as a finger), and detects an input by the finger Based on the time measured by the timer provided in the control unit 11, it is determined whether or not the object is being handwritten by the pen. Then, referring to the function association information, the function corresponding to the finger input is specified according to whether or not the object is being handwritten, and the specified function is executed. The object operation control unit may be configured as hardware, or may be configured as an object operation control program that causes the control unit 11 to function as an object operation control unit.

  The display unit 12 includes an LCD (Liquid Crystal Display), an organic EL (electroluminescence) display, or the like, and displays an object input by handwriting with a pen. In addition, an object on which functions such as division, combination, range designation, partial erasure, enlargement / reduction, and change of color / thickness / line type are executed according to a finger input is displayed.

  The operation unit 13 is a touch sensor including a grid-like transparent electrode arranged on the display unit 12, and discriminates between contact with a pen and contact with a finger based on electromagnetic, electrostatic capacity, pressure, contact area, and the like. To detect. For example, it is configured to have both a function to detect electromagnetic changes and a function to detect capacitance changes, and detects the contact of the pen based on the electromagnetic change caused by the magnetic material embedded in the tip of the pen, Finger contact can be detected based on the change in capacitance. In addition, it has a structure that has both a function to detect a change in pressure and a function to detect a change in capacitance, detects a pen contact based on a change in pressure, and detects a finger contact based on a change in capacitance. Can be detected. Moreover, it is set as the structure provided with the function to detect the change of an electrostatic capacitance or a pressure, and it can identify and detect the contact of a pen and the contact of a finger based on the area and shape in which the electrostatic capacitance and the pressure changed.

  Hereinafter, processing executed by the object operating device 10 having the above-described configuration will be described with reference to the flowcharts of FIGS.

  First, the process for creating a new handwritten input object will be described with reference to the flowchart of FIG. This flow is called in S314 in the flowchart of FIG.

  First, the control unit 11 initializes variables such as the position coordinates of the object on the touch sensor, and creates a new handwritten input object (S101). Next, the control unit 11 sets a timer used for determining whether or not the object is being input by handwriting to a predetermined time (S102), and starts the timer (S103). This predetermined time can be arbitrarily set, and when the timer is started, the timer value decreases according to the elapsed time.

  Next, processing for determining whether or not an object is being input by handwriting will be described with reference to the flowchart of FIG. This flow is executed at regular intervals for each object regardless of whether or not there is an input to the touch sensor.

  First, the control unit 11 determines whether the timer for the handwritten input object is operating (whether the timer value has a positive value) (S201). If the timer is not operating, the process is terminated because handwriting is not being input.

  When the timer is operating, the control unit 11 determines whether or not there has been a finger operation input to this object from the previous cycle to the present (S202). When there is a finger operation input to this object, the control unit 11 determines whether there is an operation instructing the end of handwriting input in the finger operation (S203).

  When there is an operation for instructing the end of the handwriting input, the control unit 11 stops the timer of the object and sets a negative integer as the timer value (S204). On the other hand, if there is no operation for instructing the end of handwriting input, the timer value of the object is reset to a predetermined time, and the timer is restarted (S206).

  In S202, if there is no finger operation input to this object from the previous cycle until now, the control unit 11 decreases the timer value by a certain time (one cycle time) (S207). And the control part 11 judges whether a timer value is negative (S208), and when a timer value becomes negative, it stops a timer (S209).

  Thereafter, the control unit 11 displays a state during handwriting input on the handwritten input object (S205). For example, as shown in FIG. 2D, the timer value is displayed as a bar graph below the handwritten input object.

  Next, the operation control process of the handwritten object will be described with reference to the flowchart of FIG.

  First, the control unit 11 determines whether the touch input to the operation unit 13 (touch sensor) is by a finger (or hand) or a pen (S301).

  When the touch input is made with a finger (or hand), the control unit 11 determines whether the operation target is a handwritten input object or a page area (S302).

  When the operation target is a handwritten input object, the control unit 11 analyzes the touch input, specifies a finger operation (gesture) (S303), refers to the function association information, and the finger operation is handwritten. It is determined whether the operation is a function switching depending on whether or not the input is being performed (whether the function associated with the gesture is different between handwriting input and non-handwriting input) (S304).

  When the function is switched depending on whether or not the finger operation is during handwriting input, the control unit 11 determines whether the timer for the object is operating (S305), and when the timer is operating When the object is operated by executing a function associated in advance as a function during handwriting input (S306) and the timer is not operating, the function associated in advance as a function for non-handwriting input is performed. Is operated (S308).

  This will be specifically described with reference to the function association information in FIG. 5 and the gestures in FIGS. 1 and 2. For example, when a gesture is performed in which a finger is moved from one object toward the other object, during non-handwriting input, the object is determined to be a drag operation as shown in FIG. However, during handwriting input, a function for combining objects based on the determination of a combining operation is executed as shown in FIG. Further, when a gesture for moving a finger across the object is performed, a function for moving the object based on a drag operation is similarly executed during non-handwriting input. As shown in (2), it is determined that the operation is a division operation, and a function for dividing the object into two is executed. In addition, when a gesture of reciprocating a finger on an object is performed, a function for moving the object based on the determination of a drag operation is executed in the same way during non-handwriting input. As shown in the figure, a function for erasing a part of the object is executed based on the partial erasure operation. In addition, when a gesture of touching an object with a finger is performed, during non-handwriting input, a function of selecting an object by performing a tap operation as shown in FIG. 1A is executed. A function of changing the color / thickness / line type of the line constituting the object is executed by determining the operation to change the color / thickness / line type.

  In S304, when the finger operation is not an operation for switching the function depending on whether or not the handwriting is being input, the control unit 11 refers to the function association information and executes the function corresponding to the finger operation to execute the object. Is operated (S309).

  For example, if you touch two fingers on the opposite side of an object and make a gesture to widen / narrow the distance between the two fingers, the object is enlarged / reduced by determining that it is a pinch operation during non-handwriting input or handwriting input. Execute the function to perform.

  In S302, when the operation target is not an object but a page area, the control unit 11 analyzes the touch input and specifies a finger operation (gesture) (S310). The corresponding function is executed (S311).

  In S301, if the touch input is by a pen, the control unit 11 determines whether the touch input is an input for an object for which a handwriting input is being performed (during timer operation) ( S312).

  When the touch input is an input for an object being handwritten, the control unit 11 updates the state of the handwritten stroke according to the pen trajectory (S313), and the touch input is being handwritten. If the input is not an object, a new handwritten object is created according to the flowchart shown in FIG. 6 (S314).

  Thereafter, the control unit 11 updates the display of the object according to the change in the state of the object (S307). For example, when the object operation is performed in S306, S308, and S309, the object after executing the function associated with the operation is displayed, and when the handwriting state is updated in S313, the updated handwritten input object is displayed. If a new handwritten object is created in S314, the new object is displayed. At that time, during handwriting input, it is possible to easily confirm that handwriting input is in progress by displaying a frame surrounding the object, and it is determined that handwriting input is in progress by displaying the timer status. It is possible to easily check the remaining time.

  As described above, in this embodiment, each finger operation (gesture) is associated with a function during handwriting input and during non-handwriting input, and the object operation device 10 uses the pen for handwriting input. If a finger operation is performed during that time, the finger operation is recognized as an operation on the object being input by handwriting, and a function associated with the operation is displayed, so that a menu screen is displayed and a function is selected. Such an operation is not required, and appropriate object formation can be easily performed.

  In addition, this invention is not limited to the said Example, The structure and control can be changed suitably, unless it deviates from the meaning of this invention.

  For example, in the above embodiment, as functions associated with a specific operation for an object being handwritten, object division, combination, range designation, partial erasure, enlargement / reduction, and change of color / thickness / line type are possible. Although described, these functions are examples, and arbitrary functions applicable to an object being handwritten can be associated. Further, the correspondence relationship between the gesture and the function in the function association information in FIG. 5 is also an example, and an arbitrary gesture can be associated with an arbitrary function.

  In the above embodiment, the case where an object handwritten with a pen is operated with a finger has been described. However, in a configuration in which a touch by two types of instruction means can be identified, an object handwritten with one instruction means The present invention can be similarly applied to any case where the operation is performed by the instruction unit. For example, two types of pens with different thicknesses are used, and an object handwritten with one pen is operated with the other pen, or an object handwritten with one finger is used with the other finger. The control of the present invention can be similarly applied to the case where the operation is performed.

  INDUSTRIAL APPLICABILITY The present invention can be used for an apparatus provided with a touch panel, in particular, an apparatus provided with a touch panel having a touch sensor on the display surface capable of identifying a touch by two types of instruction means, and a program operating on the apparatus.
