Description

  The present invention relates to an information processing apparatus that includes an input surface that can detect a position designated by a user and that can input information based on the designated position.

  As electronic devices having a display surface including an input surface such as a touch panel are widely used, the opportunity for a user to perform handwriting input on the electronic device is increasing. For example, in an information terminal such as a tablet-type terminal and some home-use game machines, a form in which a user inputs a character or a figure by performing a handwriting operation with an indicator such as a finger or a stylus is common. It is.

  Therefore, techniques for improving the convenience of handwriting input in the electronic device have been widely developed. For example, in Patent Document 1 below, when two touch areas are detected, there is a touch panel device that compares the areas of both touch areas, enables a small area, and disables a large area. It is disclosed.

  Patent Document 2 below discloses a terminal device with a display function that can invalidate only the operation of a desired operation key and easily perform the invalidation operation. Further, Patent Document 3 below discloses a method for identifying various hand portions that are in contact with the surface.

JP 2006-039686 A (published on Feb. 09, 2006) JP 2009-181244 A (released on Aug. 13, 2009) JP 2012-099161 A (published May 24, 2012)

  When fatigue is accumulated in the hand holding the electronic device by using the electronic device for a long time, the user needs to change the electronic device or hold both hands. In particular, in a tablet-type terminal having a larger casing (and thus having a larger weight) than a small device such as a smartphone, the user is likely to feel fatigue.

  Here, for example, when the user changes the electronic device from one hand to the other hand (for example, the left hand to the right hand), the other hand that supports the electronic device later often comes into contact with the input surface. . This is because as the proportion of the display surface including the input surface in the housing increases, the grippable portion of the housing decreases.

  In the above case, the conventional electronic device exemplified by the touch panel device described in Patent Document 1 erroneously recognizes that an operation for input has been performed on the electronic device due to the contact. Therefore, even when the user wants to change the electronic device, the conventional electronic device accepts an input not intended by the user. The conventional techniques described in Patent Documents 2 and 3 have the same problem.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to identify information detected on the input surface and allow the user to easily grasp the casing, thereby improving user convenience. It is to provide an information processing apparatus and the like that improve the performance.

  In order to solve the above-described problem, an information processing apparatus according to one embodiment of the present invention includes an input surface that can detect a position specified by a user, and can input information based on the specified position. An information processing apparatus, wherein a first measurement unit that measures a pressure applied to the specified position and a first specified position are detected by the input surface, and the first measurement unit detects the first designation. When the first pressure applied to the position is measured and the second designated position is further detected, the second pressure newly measured at the first designated position is the first pressure. A first determination unit that determines whether or not the pressure is smaller, and an input that accepts the second designated position as input information when the first determination unit determines that the pressure is not smaller than the first pressure. Means and .

  In order to solve the above-described problem, a method for controlling an information processing device according to one aspect of the present invention includes an input surface capable of detecting a position specified by a user, and performs information based on the specified position. The information processing apparatus can control the information processing apparatus, wherein the first designated position is detected by the input surface and the first pressure applied to the first designated position is measured. A first determination step of determining whether a second pressure newly measured at the first specified position is smaller than the first pressure when the specified position is further detected; and An input step of receiving the second designated position as input information when it is determined that the pressure is not smaller than the first pressure in the first determination step.

  According to an information processing device and a method for controlling the device according to one embodiment of the present invention, the designated position detected by the input surface is a finger of a user who operates the information processing device or a user who holds the information processing device. It is possible to discriminate only information input by the latter. Accordingly, the user can contact the input surface to grasp the housing without being aware of the possibility of erroneous input.

  Therefore, the information processing device and the method for controlling the device according to one embodiment of the present invention can allow the user to easily hold the housing of the information processing device, and thus can improve the convenience for the user. There is an effect.

It is a flowchart which shows an example of the process which the said tablet type terminal performs.

  Based on FIGS. 1-5, embodiment of this invention is described in detail.

[Outline of tablet-type terminal 100]
An outline of the tablet terminal 100 will be described with reference to FIG. FIG. 1 is a block diagram showing a main configuration of the tablet terminal 100.

  As shown in FIG. 1, the tablet-type terminal (information processing apparatus) 100 includes an input surface 41 that can detect a position designated by the user (hereinafter also referred to as “contact position” or “designated position”). The information processing apparatus is capable of inputting information on the basis of the determined position.

  Based on FIG. 2, the basic operation of the tablet terminal 100 will be described. FIG. 2 is a schematic diagram showing a series of operations when the tablet-type terminal 100 held by the user with the left hand is moved to the right hand. FIG. 2A shows a state in which the user holds the tablet-type terminal with the left hand. (B) shows a state of gripping with both hands, and (c) shows a state of gripping with the right hand.

  As shown in FIG. 2A, the tablet terminal 100 detects the position of the finger (designated position 1a) that is touched by the user holding the tablet terminal, and applies pressure (first position) to the designated position. 1 pressure) 6a is measured. If the pressure exceeds the pressure threshold value, the tablet terminal 100 does not accept the designated position (first designated position, designated position) 1a as input information.

  As shown in (b) of FIG. 2, when the designated position (second designated position, designated position) 1 b is further detected by the user holding the tablet terminal 100 with both hands, the tablet type The terminal measures a pressure (third pressure) 6b applied to the designated position. In addition, the tablet terminal newly measures a pressure (second pressure) 6c applied to the designated position 1a. Note that the tablet-type terminal 100 always acquires the latest value of the pressure by measuring the pressure applied to the designated position at predetermined time intervals.

  The tablet terminal 100 determines whether or not the pressure 6c is smaller than the initially measured pressure 6a. When the pressure 6c is not smaller than the pressure 6a, the tablet terminal 100 determines that the designated position 1b is due to a user operation 7a for operating the tablet terminal, and receives information input by the designated position 1b.

  On the other hand, when the pressure 6c is smaller than the pressure 6a, the tablet terminal 100 determines that the designated position 1b is caused by a finger holding the tablet terminal, and does not accept information input by the designated position 1b. This is because when the user holds the tablet terminal 100 with both hands, the pressure 6c becomes smaller than the pressure 6a because a part of the pressure 6a is replaced by the designated position 1b.

  Therefore, when the pressure 6c is smaller than the pressure 6a, the tablet terminal 100 can determine that the designated position 1b is due to the finger of the user holding the tablet terminal. Thereby, the tablet-type terminal 100 can reject the information input by the designated position 1b.

  Note that the tablet-type terminal 100 may not accept not only the designated position 1b but also a contact position within a predetermined area including the designated position. This is because not only the fingertip but also other parts of the finger, the palm, and the like usually come into contact with the input surface 41, and information input by the contact needs to be rejected.

  The tablet terminal 100 may determine whether the sum of the pressure 6b and the pressure 6c (hereinafter also referred to as “pressure sum”) is substantially equal to the initially measured pressure 6a. If they are not approximately equal, the tablet terminal 100 determines that the designated position 1b is due to a user operation 7a that operates the tablet terminal, and accepts information input by the designated position 1b (in this case, the pressure sum is the pressure 6a). Is usually larger).

  On the other hand, when the pressure sum is substantially equal to the pressure 6a, the tablet terminal 100 determines that the designated position 1b is caused by the finger of the user holding the tablet terminal, and does not accept information input by the designated position 1b.

  Based on FIG. 3, the grounds for the tablet terminal 100 to execute the above-described processing will be described. FIG. 3 is a graph showing time transition of pressure applied to each of the two designated positions (designated position 1a and designated position 1b).

  As shown in FIG. 3, the user starts an operation of moving the tablet terminal 100 held by the left hand to the right hand from time A. At time B, the weights supported by the respective hands are equal, and at time C, the changeover is completed. Here, the pressure sum and the pressure 6a are substantially equal. This is because the weight supported by the user is constant.

  Therefore, when the pressure sum is substantially equal to the pressure 6a, the tablet terminal 100 can determine that the designated position 1b is due to the finger of the user holding the tablet terminal. Thereby, the tablet-type terminal 100 can reject the information input by the designated position 1b.

  As shown in FIG. 2C, the tablet terminal 100 may reject the information input by the designated position 1b even after the user completes the changeover.

  As described above, when a conventional electronic device is moved from one hand to the other, if the other hand that supports the electronic device comes into contact with the input surface later, the conventional electronic device is It misrecognizes that the electronic device has been operated for input. Therefore, even when the user wants to change the electronic device, the conventional electronic device has a problem that it accepts an input not intended by the user.

  On the other hand, in the tablet terminal 100, the designated position 1a or the designated position 1b detected by the input surface 41 is a finger of a user who operates the tablet terminal, or a user holding the tablet terminal 100 It is possible to identify whether it is a finger and reject only the information entered by the latter. Thereby, the user can contact the input surface 41 in order to hold the housing of the tablet terminal 100 without being aware of the possibility of erroneous input.

  Accordingly, since the tablet terminal 100 can easily allow the user to hold the housing, the convenience of the user can be improved.

[Appearance and operation example of tablet terminal 100]
An example of the appearance and operation of the tablet terminal 100 will be described with reference to FIG. 4A is a schematic diagram illustrating an appearance example of the tablet terminal 100, and FIG. 4B is a schematic diagram illustrating an operation example of the tablet terminal 100 by the user.

  As shown in FIG. 4A, the tablet terminal 100 includes an input surface 41, a display surface 72, and a power switch 43.

  In addition, in order to clarify the function which each structure has, FIG. 1 shows the input surface 41 and the display surface 72 separately. For example, when the input surface 41 is a touch panel and the display surface 72 is a liquid crystal display, As shown to (a) of FIG. 4, both may be comprised integrally. Thereby, since the contact position of the stylus 4 with respect to the input surface 41 and the display position of the figure etc. which the display surface 72 displays according to the said contact correspond, the user can acquire a natural input feeling.

  As shown in FIG. 4B, the user touches the input surface 41 with the stylus 4 and designates the position on the input surface to the tablet terminal 100 (by giving the coordinates on the input surface). ), Information that can specify an instruction to select an icon or the like can be given to the tablet terminal 100.

  FIG. 4B illustrates a state where the user holds the tablet terminal 100 with the left hand and the stylus 4 held with the right hand contacts the input surface 41. However, the user's hand holding the tablet terminal 100 or the stylus 4 may be the right hand or the left hand.

  In addition, the user can use a finger instead of a pointing tool such as a stylus to operate the tablet terminal 100. That is, throughout this description, “stylus” and “indicator” include “user's finger”.

  Further, it is described as “the user makes the stylus contact the input surface”. However, when the input surface 41 is, for example, a touch panel that can detect the proximity of the stylus, the tablet terminal 100 can operate in the same manner as in the case of contact by detecting the proximity of the stylus to the input surface 41. .

  As described above, the tablet terminal 100 is a portable information processing apparatus. Here, it should be noted that a function equivalent to that of the tablet terminal 100 can be realized by a mobile phone, a smartphone, a personal computer, or the like. That is, the terminal does not have to be a tablet terminal as long as the electronic device can acquire information necessary for a predetermined operation.

[Configuration of tablet-type terminal 100]
Based on FIG. 1, the structure of the tablet-type terminal 100 is demonstrated. From the viewpoint of ensuring the conciseness of the description, portions not directly related to the present embodiment are omitted from the description of the configuration and the block diagram (for example, FIG. 4 shows the power switch 43, but FIG. Omitted). However, in accordance with the actual situation of implementation, the tablet terminal 100 may include the omitted configuration.

  Hereinafter, input surface 41, measurement unit 20 (pressure measurement unit 21, area measurement unit 22), determination unit 30 (pressure sum determination unit 31, threshold determination unit 32), change detection unit 50, information input unit 10, display The function which each structure bears in the order of the part 70 (display control part 71, display eyes 72) is demonstrated.

  The input surface 41 outputs an input signal 5 including information on the position of the touched user's finger or stylus 4 on the input surface to the pressure measurement unit 21, the area measurement unit 22, and the change detection unit 50. As long as the input surface 41 is a device capable of outputting the input signal 5, the type of hardware is not limited to the touch panel.

  The measurement unit 20 is a device including various sensors that can measure the pressure applied to the contact position and the area of the contact position. The measurement unit 20 includes a pressure measurement unit 21 and an area measurement unit 22.

  The pressure measuring unit (first measuring means) 21 measures the pressure applied to the designated position based on the input signal 5 input from the input surface 41, and uses the pressure information 2a indicating the pressure as the pressure sum determining unit 31 and Output to the threshold determination unit 32.

  The area measuring unit (second measuring means) 22 is based on the input signal 5 input from the input surface 41, the area in contact with the input surface 41 at the contact position (the area of the finger in contact with the input surface 41, hereinafter “ The area information 2b indicating the area is output to the pressure measuring unit 21.

  When the area information 2b is input from the area measuring unit 22, the pressure measuring unit 21 can measure a pressure corresponding to the area information. That is, since the contact area of the user's finger increases as the pressure applied to the input surface 41 increases, the pressure measurement unit 21 performs, for example, a predetermined function calculation (for example, proportional calculation) using the area information 2b as an input. The pressure information 2a can also be acquired. Further, in the case where the input surface 41 is a touch panel employing an electrostatic capacitance method, the area measuring unit 22 can acquire the contact area by a conventional technique without mounting a special sensor.

  Based on the pressure information 2a input from the pressure measurement unit 21, the determination unit 30 (first determination unit) determines whether the contact detected by the input surface 41 is due to the finger of the user who operates the tablet terminal. , Whether the user's finger is holding the tablet terminal is identified.

  That is, when the designated position 1 a is detected by the input surface 41 and the pressure 6 a applied to the designated position 1 a is measured by the pressure measuring unit 21, the determination unit 30 determines that the designated position 1 b is further detected. It is determined whether the pressure 6c newly measured in 1a is smaller than the pressure 6a.

  Specifically, when the pressure information 2a is input from the pressure measurement unit 21, the pressure sum determination unit 31 determines whether the pressure 6c indicated by the pressure information is smaller than the pressure 6a, and the determination result 3a Is output to the information input unit 10. Determination unit 30 includes a pressure sum determination unit 31 and a threshold determination unit 32.

  The pressure sum determination unit (first determination means) 31 determines whether the sum (pressure sum) of the pressure 6b and the pressure 6c applied to the designated position 1b is substantially equal to the pressure 6c. Specifically, when the pressure information 2a is input from the pressure measurement unit 21, the pressure sum determination unit 31 has a sum (pressure sum) of the pressure 6b and the pressure 6c indicated by the pressure information substantially equal to the pressure 6a. And the determination result 3 a is output to the information input unit 10.

  The threshold determination unit (second determination unit) 32 determines whether or not the pressure indicated by the pressure information 2a input from the pressure measurement unit 21 exceeds the pressure threshold, and displays the determination result 3b. Output to the information input unit 10.

Pressure threshold (predetermined threshold) lambda ₁ is represented by, for example, by the following equation.

Here, m represents the weight (kg) of the tablet terminal 100, g represents the acceleration of gravity (m / s ² ), and μ represents the coefficient of static friction. When m = 0.220, g = 9.80665, μ = 0.4, according to the above equation, when the pressure value indicated by the pressure information 2a exceeds λ ₁ = 5.3936575≈5.4 (N), the threshold value determination unit 32 The determination result 3b indicating that the pressure value exceeds the pressure threshold value is output to the information input unit 10.

  The change detection unit (detection means) 50 detects that the specified position has changed as a result of the user operation 7a specifying the position on the input surface 41 moving along the input surface.

  Specifically, the change detection unit 50 acquires information on the designated position included in the input signal 5 input from the input surface 41. Then, the change detection unit 50 compares the previous value of the designated position with the detection result 7c indicating that the designated position has not changed if both are substantially the same as the information input unit together with the current value of the designated position. 10 is output. On the other hand, if both are not substantially the same, the change detection unit 50 outputs a detection result 7c indicating that the designated position has changed to the information input unit 10 together with the current value of the designated position.

  In order to find a position where the batter is easy to grip, the user can search for a position where the batter can easily grasp the tablet terminal 100 by adjusting the position where the batter is gripped by shifting the hand holding the grip on the grip. It is possible to adjust the gripping position by shifting the hand gripping the tablet terminal on the input surface 41. In addition, the display may be blocked by a finger holding the tablet terminal 100.

  As described above, in order for the change detection unit 50 to detect that the designated position has changed, after gripping the housing of the tablet terminal 100 with the finger in contact with the input surface 41, the finger is placed on the input surface. By moving it, the user can search for a position more suitable for gripping. Therefore, since the tablet terminal 100 can make the user grip the casing of the tablet terminal more easily, the convenience of the user can be further improved.

  Here, the change detection unit 50 detects that the designated position has changed even when the user releases the finger holding the tablet terminal 100 from the input surface 41 for a moment (for example, 100 milliseconds) and makes it contact again. It's okay.

  When the determination result 3a indicating that the pressure 6c is not smaller than the pressure 6a is input from the determination unit 30, the information input unit (input unit) 10 receives the specified position 1b as the input information, and is specified by the specified position. The input information 7b is output to the display control unit 71.

  In addition, when the determination result 3a indicating that the pressure sum is not substantially equal to the pressure 6a is input from the pressure sum determination unit 31, the information input unit 10 receives the specified position 1b as the input information, and depending on the specified position, The specified input information 7b may be output to the display control unit 71.

  Further, when the determination result 3b indicating that the pressure 6a does not exceed the pressure threshold value is input from the threshold determination unit 32, the information input unit 10 receives the specified position 1a as the input information, The input information 7b specified by the position is output to the display control unit 71.

  Furthermore, when the information input unit 10 does not accept the designated position 1a or the designated position 1b as input information, when the detection result 7c indicating that the designated position has changed is input from the change detection unit 50, The designated position 1a or designated position 1b after the change is not accepted as input information.

  For example, when a dialog for allowing the user to select “YES” or “NO” is displayed in a pop-up, the information input unit 10 accepts the designated position 1a or the designated position 1b as input information because the display has changed. In such a case, for example, there is a problem that an option unintended by the user is selected because the button of the dialog is displayed at the designated position.

  Therefore, in order to avoid such a problem, when the information input unit 10 does not accept the designated position 1a or the designated position 1b as the input information, the designation is performed regardless of the change in the content displayed on the display surface 72. The position may not be accepted as input information.

  For example, when the application executed by the tablet terminal 100 is switched, if the information input unit 10 accepts the designated position 1a or the designated position 1b as input information, for example, the application after the switching is performed. There is a problem that an input unintended by the user is performed.

  Therefore, in order to avoid such inconvenience, the information input unit 10 does not accept the designated position 1a or the designated position 1b as input information, regardless of changes in processing executed by the tablet terminal 100. It is not necessary to accept the designated position as input information.

  As described above, the information input unit 10 does not accept the specified position 1a or the specified position 1b as input information regardless of changes in content or processing, so that the user is not aware of the possibility of erroneous input. The input surface can be contacted to grip the housing. Therefore, since the tablet terminal 100 can make the user grip the casing of the tablet terminal more easily, the convenience of the user can be further improved.

  The display unit 70 (output means) outputs that the user can recognize that the specified position 1a or the specified position 1b is not received as information input by the information input unit 10. For example, the display unit 70 may display the periphery of the designated position with reduced brightness (or increased brightness), or display the designated position to be a recess.

  Alternatively, the display unit 70 may emit a predetermined sound from a speaker (not shown in FIG. 1). Further, when the change detection unit 50 detects that the designated position has changed, the display unit 70 may change the display or the predetermined sound following the change in the designated position.

  Thereby, the tablet-type terminal 100 can clearly indicate to the user that the designated position 1a or the designated position 1b is determined by the finger of the user holding the tablet-type terminal. Can be given.

  When the change detection unit 50 does not detect that the display unit 70 has changed (that is, when the usage status of the tablet terminal 100 by the user does not change), the information input unit 10 specifies the specified position 1a or the specified position 1b. It may be interrupted that the user can recognize that the information is not accepted as input information.

  Alternatively, the display unit 70 may output only for a predetermined time (for example, when the designated position is changed or for a certain time after the change). Thereby, the tablet terminal 100 can improve the visibility of the content displayed on the display surface 72.

  In addition, for example, when the photograph is displayed on the full screen by the tablet terminal 100, the output may deteriorate due to the output. Therefore, the display unit 70 may interrupt the output when a predetermined process is being executed by the tablet terminal 100.

  Furthermore, the display unit 70 is displayed when the user resumes using the tablet terminal 100, or (for example, by changing the orientation of the input surface 41 with respect to the ground, such as by overturning the housing of the tablet terminal 100). However, when the display orientation of the tablet terminal 100 is changed, the designated position 1a or the designated position 1b that has not been accepted as the information input by the information input unit 10 may be output so that the user can recognize it.

  Thereby, since the tablet-type terminal 100 can remind the user that the designated position 1a or the designated position 1b has not been accepted as information by the tablet-type terminal, it can give the user a sense of security. . The display unit 70 includes a display control unit 71 and a display surface 72.

  The display control unit 71 outputs the display data 7 d to the display surface 72 so that the result of the processing according to the input information 7 b can be displayed on the display surface 72. The display data 7d may be, for example, an image in a bitmap format, an image according to another format, or another data format suitable for display. Note that the display control unit 71 only needs to include content that can be converted into the display data 7d, such as a general display adapter.

  The display surface 72 is a device that displays the display data 7 d input from the display control unit 71. In the present embodiment, a liquid crystal display (LCD) is mainly assumed. However, a device having a display function (for example, a display element is driven based on display data 7d input from the display control unit 71). The type of hardware is not limited as long as it is a device provided with a driver circuit.

  Although not shown in FIG. 1, the tablet terminal 100 may include a storage unit for storing a time change of a designated position and a pressure threshold value. Note that the storage unit can be constituted by, for example, a hard disk, a semiconductor memory, a DVD, or the like. The storage unit may be a device built in the tablet terminal 100 or an external storage device connected to the outside of the tablet terminal 100 so as to be communicable.

[Processes executed by the tablet terminal 100]
Based on FIG. 5, the flow of processing executed by the tablet terminal 100 will be described. FIG. 5 is a flowchart illustrating an example of processing executed by the tablet terminal 100. In the following description, parenthesized “˜step” represents each step of the control method.

  When the input surface 41 detects the first contact (designated position 1a) (YES in step 1; hereinafter, “step 1” is abbreviated as “S1”), the pressure measurement unit 21 applies the pressure 6a applied to the designated position 1a. Is measured (S2). Next, the threshold determination unit 32 determines whether or not the pressure exceeds the pressure threshold (5.4N) (S3).

  When the pressure does not exceed the pressure threshold value (NO in S3), the information input unit 10 receives the designated position as input information (S9).

  On the other hand, when the pressure exceeds the pressure threshold (YES in S3), when the input surface 41 detects the second contact (specified position 1b) (YES in S4), the pressure measuring unit 21 specifies The pressure 6b applied to the position 1b is measured. Further, the pressure measuring unit 21 newly measures the pressure 6c applied to the designated position 1a (S5).

  The determination unit 30 determines whether or not the pressure 6c is smaller than the pressure 6a (first determination step). Here, the pressure sum determination unit 31 may determine whether or not the sum of the pressure 6b and the pressure 6c (pressure sum) is substantially equal to the pressure 6a (S7, first determination step). When it is determined that the determination unit 30 is not smaller or when it is determined that the pressure sum determination unit 31 is substantially equal (YES in S7), the information input unit 10 accepts the designated position 1b as input information (S9). , Input step).

  On the other hand, when it is determined that it is not small (substantially equal or larger) (NO in S7), until the input surface 41 no longer detects the designated position 1a or the designated position 1b (NO in S8), the tablet terminal 100 is The processes of S5 to S7 are repeated.

[Effects of the tablet terminal 100]
The tablet terminal 100 identifies whether the designated position 1 detected by the input surface 41 is from a finger of a user who operates the tablet terminal or a user's finger holding the tablet terminal, and the latter Only the information entered by can be rejected. Thereby, the user can contact the input surface 41 in order to hold the housing without being aware of the possibility of erroneous input.

  Therefore, the tablet-type terminal 100 can allow the user to easily hold the casing, and thus has an effect of improving the convenience for the user.

[Summary]
