Description

  The present invention provides a tactile presentation device corresponding to a touch panel operation and a tactile sensation that presents a tactile sensation corresponding to the operation to a finger different from the operated finger when the user performs a touch operation on display target information displayed on the touch panel. The present invention relates to a presentation method, a tactile presentation program, and a portable terminal equipped with a tactile presentation device.

  With the widespread use of devices equipped with touch panels such as smartphones and tablet terminals, improvements in the comfort and accuracy of operations have become important issues. By using the touch panel, intuitive operation such as direct touch operation with the finger on the part where the icon to be selected is displayed is possible, improving operational comfort, but lacking tactile feedback such as click feeling. It is known that the input accuracy decreases.

  Hereinafter, as an embodiment of the present invention, a smartphone equipped with a tactile sense presentation device corresponding to a touch panel operation will be described in detail.

<Configuration of a smartphone equipped with a tactile presentation device according to an embodiment>
The configuration of a smartphone equipped with a tactile sense presentation device according to the present embodiment will be described with reference to FIG. FIG. 1 is an external perspective view of the smartphone 1 viewed from the back side. The smartphone 1 is provided with an electrotactile display 3 in which a plurality of electrodes are arranged in a matrix at a position slightly above the center on the back side of the terminal body 2. A touch panel 21, which will be described later, is installed on the front surface side of the terminal body 2, and the electric tactile display 3 is installed on the back surface side of the terminal body 2 so as to face the opposite direction to the touch panel 21. The terminal body 2 and the electric tactile display 3 are connected in a state where USB serial communication is possible.

  Detailed functional configurations of the terminal body 2 and the electric tactile display 3 will be described with reference to the block diagram of FIG. The terminal body 2 includes a touch panel 21, an input information acquisition unit 22, a display control unit 23, a capture processing unit 24, a cut-out processing unit 25, a presentation position information generation unit 26 as a stimulator identification information generation unit, And a transmission unit 27.

  The touch panel 21 displays display target information having a predetermined shape and inputs information related to a touch operation by the user. The input information acquisition unit 22 acquires information input from the touch panel 21. The display control unit 23 displays the display target information specified based on the input information acquired by the input information acquisition unit 22 at a predetermined position on the touch panel 21. The capture processing unit 24 captures display information of the entire screen of the touch panel 21 on which display target information is displayed.

  The cutout processing unit 25 specifies the touch operation position by the user on the touch panel 21 based on the input information acquired by the input information acquisition unit 22. Then, the display information around the specified touch operation position is cut out from the display information of the entire screen captured by the capture processing unit 24. Here, the “display information around the touch position” is display information of a predetermined area including the touch operation position, and the “predetermined area” is when a person touches the touch panel 21 around the touch operation position. It is an area | region of the magnitude | size preset as a range equivalent to being pressed.

  The presentation position information generation unit 26 reverses the display information of the predetermined area acquired by the cut-out processing unit 25 to the left and right and presents the electrodes to be energized in the electrode group 31 to be described later in order to be presented tactilely by the electric tactile display 3. Current-carrying electrode specifying information (stimulator specifying information of the present invention) for specifying is generated.

  The transmission unit 27 transmits the energization electrode specifying information generated by the presentation position information generation unit 26 to the electrotactile display 3.

  The electrotactile display 3 includes an electrode group 31, a receiving unit 32, and a tactile sense presentation control unit 33.

  The electrode group 31 is configured by arranging a plurality of electrodes as tactile stimulators in a matrix on a plane having an area to which the index finger comes into contact when the terminal node of a human index finger is applied. The electrode group 31 is provided with a plurality of switches for ON / OFF operation of energization to each electrode (output of electrical stimulation that is a stimulation factor from the electrode). In the electrode group 31, the receiving unit 32 receives the energizing electrode specifying information transmitted from the terminal body 2. The tactile sense presentation control unit 33 controls the switches of the electrode group 31 so that electricity flows through the electrodes specified by the energized electrode specifying information received by the receiving unit 32.

<Operation of Smartphone Equipped with Tactile Presentation Device According to One Embodiment>
Next, the operation in the case of performing tactile presentation on the electrotactile display 3 by following the operation of the touch panel 21 by the user using the smartphone 1 according to the present embodiment will be described. In this embodiment, as shown in FIG. 3, the user holds the smartphone 1 while bringing the terminal of the index finger of the right hand into contact with the electrode group 31 and operates the touch panel 21 with the thumb of the right hand as shown in FIG. 4. . Here, a thumb that performs an operation on the touch panel 21 is referred to as an “operation finger”, and an index finger that receives a tactile presentation by electrical stimulation is referred to as a “presentation finger”.

  As described above, when the user who holds the smartphone 1 performs an operation on the touch panel 21, a process executed in the terminal body 2 will be described with reference to a flowchart of FIG. 5.

  First, when display target information is designated by an operation on the touch panel 21 by the user (“YES” in S1), information indicating the operation content is acquired by the input information acquisition unit 22. Based on the acquired information, the specified display target information is displayed at a predetermined position on the touch panel 21 under the control of the display control unit 23 (S2). Here, as shown in FIG. 6, it is assumed that a diagonal line A from the upper left to the lower right is designated as display target information and displayed on the upper part of the touch panel 21.

  Next, display information of the entire screen of the touch panel 21 on which the oblique line A is displayed is captured by the capture processing unit 24 (S3).

  Next, when a new touch operation is performed by the user's operation finger in the vicinity of the display of the oblique line A on the touch panel 21 on which the oblique line A is displayed (“YES” in S4), the cutout processing unit 25 causes the touch panel 21 to The touch operation position (center coordinates of the touch operation) is specified as the touch operation position (S5).

  Further, in the cutout processing unit 25, display information in a predetermined area including the specified touch operation position is cut out from the display information of the entire screen captured by the capture processing unit 24 (S6). Here, when the user performs a touch operation near the oblique line A, a part of the oblique line A is included in the predetermined area.

  Next, in the presentation position information generation unit 26, in order to cause the display information cut out by the cut-out processing unit 25 to be horizontally reversed and presented by the electric tactile display 3, the electrodes in the corresponding electrode group 31, that is, Current-carrying electrode specifying information for specifying an electrode to be energized in the electrode group 31 is generated (S7). The generated energizing electrode specifying information is transmitted from the transmitting unit 27 to the electric tactile display 3 (S8).

  In the electrotactile display 3, the energizing electrode specifying information transmitted from the terminal body 2 is received by the receiving unit 32, and the tactile sense presentation control unit 33 causes the electrode group to flow electricity to the electrode specified by the energizing electrode specifying information. 31 switches are controlled. Thus, by energizing and controlling the switch of the predetermined electrode, it is possible to present a feeling as if the user's presentation finger touched the irregularities in the shape of the corresponding portion of the oblique line A.

  Next, in the terminal main body 2, when the touch state of the operation finger on the touch panel 21 is continued ("YES" in S9), the process returns to step S5, and the processes of steps S5 to S8 are repeated. Here, a process when the user slides the operation finger in the vicinity of the display of the hatched line A on the touch panel 21 will be described.

  For example, as shown in FIG. 7A, when a position away from the oblique line A displayed on the touch panel 21 is touched and the partial shape information of the oblique line A does not exist in a predetermined area including the touch position information, None of the electrode groups 31 of the tactile display 3 is energized (FIG. 7B).

  Thereafter, when the user slides the operation finger while touching the touch panel 21, and the display of the slanted line A overlaps the lower left portion of the operation finger as shown in FIG. 8A, the cut-out display information is reversed left and right. Since the shape is tactilely presented at the lower right portion of the presentation finger, the electrode indicated by the black circle in FIG. 8B in the electrode group 31 is energized.

  Further, when the user slides the operation finger and the display of the hatched line A overlaps with the vicinity of the center of the operation finger as shown in FIG. 9A, the shape obtained by horizontally inverting the clipped display information is the center of the presentation finger. The electrodes indicated by the black circles in FIG. 9B in the electrode group 31 are energized so that a tactile sensation is presented to the portion.

  Further, when the user slides the operating finger and the display of the oblique line A overlaps with the vicinity of the upper right of the operating finger as shown in FIG. 10A, the shape obtained by horizontally flipping the cut out display information is the upper left of the presenting finger. The electrodes indicated by black circles in FIG. 10B in the electrode group 31 are energized so that a tactile sensation is presented to the part.

  That is, as shown in FIG. 7 → FIG. 8 → FIG. 9 → FIG. 10, when the display finger is slid on the display information in an oblique direction from the upper right to the lower left, the presentation finger in contact with the electric tactile display 3 is moved from the lower left. The contact information is sequentially presented so that the display information moves in an oblique direction toward the upper right. Similarly, for example, when the display finger is slid horizontally from the left to the right with the operation finger, the display information is moved so as to move from the right side to the left side of the pressed part of the operation finger. Following this action, the tactile display sequentially displays the tactile sense so that the left-right inverted display information moves from the right side to the left side, and the presenting finger also moves from the right side to the left side of the finger in the same way as the operating finger. The tactile sensation is recognized so that the display information moves.

  In this way, by sequentially updating the information presented to the presentation finger by tactile movement following the movement of the operation by the operation finger, the shape of the display information is as if the presentation finger is fixed, even though the presentation finger is fixed. You can feel as if you are touching while sliding on the uneven surface.

  In other words, since the shape of the information can be recognized as a tactile sensation by touching the information displayed on the screen, for example, a visually handicapped person can recognize the shape of the information displayed on the smartphone.

  In the above-described embodiment, the touch panel 21 is equipped with a means for detecting the strength of the press by the user's touch operation, and the area of the area for cutting out the display information and the area to be presented based on the detected information of the pressure strength. It may be changed. For example, when a strong touch operation is performed, the area of the area where the display information is cut out and the area to be presented are widened, and when the touch operation is weak, the area of the area where the display information is cut out and the area where the information is presented are reduced. Can also follow and can present a tactile sensation to the presenting finger.

  In the above-described embodiment, the case where the tactile display is configured by a plurality of electrodes has been described. However, the tactile display is configured using a piezoelectric element such as a piezoelectric element or MEMS (Micro Electro Mechanical Systems) technology, and presents a tactile stimulus. You may do it.

  In addition, each function of the cutout processing unit, the presentation position information generation unit, and the tactile presentation control unit of the tactile presentation device of the present embodiment can be programmed and incorporated into the computer, so that the computer can be constructed as a tactile presentation device. It is.

<Verification experiment on recognition accuracy of shape presented by tactile display on tactile display>
As described above, when recognizing the shape of the information displayed on the touch panel 21 based on information tactilely presented to the presenting finger from the electric tactile display 3 following the operation by the operation finger, the user operates the operation finger. It is necessary to recognize the shape of the display target information by fusing the touch perception of the presentation finger. Therefore, in order to verify whether the accuracy of the recognition process is sufficient, the following experiment was performed.

[Verification experiment (1)]
In the verification experiment (1), four types of figures with different angles of (a) horizontal line, (b) diagonal line from lower left to upper right, (c) vertical line, (d) diagonal line from upper left to lower right in FIG. Information was used as display target information.

  The experiment is performed under the conditions of two patterns, and one is operated with one hand using the thumb of the hand holding the smartphone 1 as the operation finger and the index finger of the same hand as the presentation finger, as described in the above-described embodiment. The one-hand experiment is to perform the presentation, and the other is to operate and present with both hands using the finger of the hand different from the hand holding the smartphone 1 as the operation finger and the index finger of the hand holding the smartphone 1 as the presentation finger. This is a two-handed experiment.

  The test subjects were six men aged 22 to 27 (average 23 years), and they all handle smartphones on a daily basis.

  Further, the physical size of the presented figure is adjusted to be the same on the touch panel 21 and the electric tactile display 3, and for example, when a 1 cm operation finger is moved on the touch panel 21, the electric tactile display 3 is displayed. The displayed figure also moved 1cm.

  Then, the above four types of figures are sequentially presented at predetermined positions on the touch panel 21 (inside a rectangular frame presented so as to have the same area as the electrotactile display 3) in a state where the subject cannot visually recognize. When the subject slides within the frame on the touch panel 21, the figure that the subject has recognized is answered by tactile presentation performed on the electrotactile display 3 following this operation.

  The tactile sensation presented by the electrotactile display 3 was performed 20 times in one set of experiments by randomly performing the above four types of figures 5 times.

  In order to eliminate the influence of the order effect, the order of the figures presented in the one-handed experiment and the two-handed experiment was changed for each subject.

  FIG. 12 and FIG. 13 show the validity rate of the test subject's answer for each graphic information obtained by the verification experiment (1). FIG. 12 shows the verification result obtained by the one-handed experiment, and FIG. 13 shows the verification result obtained by the two-handed experiment.

  In the two-hand experiment, (a) the correct answer rate of the horizontal line is 70%, (b) the correct answer rate of the diagonal line from the lower left to the upper right is 80%, (c) the correct answer rate of the vertical line is 73%, and (d) from the upper left. The correct answer rate of the slanted line toward the lower right is 80%, which is slightly inferior to the one-handed experiment, but both were high.

  Moreover, in the said verification experiment (1), the result of having calculated the average response time until a test subject answers from a test start about each one-handed experiment and a two-handed experiment is shown in FIG. In this result, the average response time for the one-handed experiment was 3.9 seconds, whereas the average response time for the two-handed experiment was 6.7 seconds, which was greater when operating with one hand than when operating with both hands. It was found that the figure could be recognized quickly.

[Verification experiment (2)]
In the verification experiment (2), four types of graphic information having different angles of (e) square, (f) circle, (g) triangle, and (h) cross mark in FIG. 15 were used as display target information.

  The test was performed under the same conditions as in the verification experiment (1) except that the test subjects were four men aged 22 to 24 (average 23 years).

  FIG. 16 and FIG. 17 show the correct rate of the test subject's answer for each graphic information obtained by the verification experiment (2). FIG. 16 shows the verification result obtained by the one-handed experiment, and FIG. 17 shows the verification result obtained by the two-handed experiment.

  In the one-handed experiment, (e) square correct answer rate is 85%, (f) circle correct answer rate is 95%, (g) triangle correct answer rate is 95%, and (h) cross mark correct answer rate is 100%. , Both were high.

  In the two-handed experiment, (e) the square correct answer rate is 80%, (f) the circle correct answer rate is 85%, (g) the triangle correct answer rate is 85%, and (h) the cross mark correct answer rate is 100%. Although it was slightly inferior to the one-handed experiment, it was still high.

  Moreover, in the said verification experiment (2), the result of having calculated the average response time until a test subject answers from a test start about each one-handed experiment and a two-handed experiment is shown in FIG. In this result, the average response time for the one-handed experiment was 6.1 seconds, whereas the average response time for the two-handed experiment was 7.96 seconds, which was greater when operating with one hand than when operating with both hands. It was found that the figure could be recognized quickly.

  Based on the verification experiments (1) and (2) described above, the shape of the information displayed on the touch panel is displayed by the user using the smartphone according to the invention of the present application and the information presented on the presenting finger by following the operation with the operating finger. It has been proved that the recognition accuracy is high in any shape figure. In particular, a high correct answer rate (80% each) was obtained for (b) the diagonal line from the lower left to the upper right and (d) the diagonal line from the upper left to the lower right, which were considered to be prone to recognition errors. Proved its height.
