  However, as a research on this type of see-through HMD device, although the development of technology that performs input operations such as drawing and operation commands based on the user's physical movements on the virtual object, There are still few studies on the tactile sensation used.

  Therefore, the present invention has been made in consideration of the above points, and proposes a tactile illusion presentation device and a tactile illusion presentation program capable of causing a user to have an illusion of tactile stimulation based on a virtual object stereoscopically displayed in a real space.

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

(1) About the see-through type HMD device of the present invention In FIG. 1, reference numeral 1 denotes a see-through type HMD device as a tactile illusion presenting device of the present invention, an HMD unit 2a that can be mounted on the user's head, and this HMD unit 2a And a control box 2b connected to the. The control box 2b includes a control unit 3 having a microcomputer configuration including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and an operation unit 4 including various buttons such as a power button. The external interface 5 and the storage unit 6 are connected to each other via a bus B, and the HMD unit 2a is connected to the external interface 5 via the external interface 5.

  The control unit 3 loads the tactile illusion presentation program stored in the ROM in advance into the RAM and starts it up, thereby controlling the various functions in the see-through type HMD device 1 and executing the tactile illusion presentation process. The image display unit 7 provided in the HMD unit 2a can display a predetermined image as a virtual object in a real space where the user exists.

  In practice, when the execution command for the tactile sensation presentation process is given via the operation unit 4, the control unit 3 reads the left-eye image data and the right-eye image data stored in advance in the storage unit 6, The image data for the left eye and the image data for the right eye can be sent to the image display unit 7 of the HMD unit 2a via the external interface 5. Here, when the HMD unit 2a is mounted on the user's head, the image display unit 7 can be positioned on the right and left eyes of the user, but the image display unit 7 is positioned on the right and left eyes. However, the user can visually recognize the external image of the real space as it is.

  In this case, the image display unit 7 displays the left-eye image generated based on the left-eye image data on the left-eye display surface that is arranged to face the left eye, and based on the right-eye image data. The generated right-eye image is displayed on the right-eye display surface that is disposed to face the right eye, and different images can be simultaneously presented to the left eye and the right eye. The image display unit 7 can stereoscopically display the virtual object 8 as shown in FIG. 2 in the real space where the user exists by binocular parallax generated by the left-eye image and the right-eye image.

  Thus, the image display unit 7 gives the user the illusion that the virtual object 8 generated by the image actually exists in the real space where the user exists, and that the virtual object 8 is floating in front of the user's eyes. Can be given.

  Here, in the case of this embodiment, the virtual object 8 is formed of a semi-transparent sphere so that the user can visually recognize the back background as it is. In addition, the virtual object 8 is provided with a shadow representing unevenness on the surface by a shading pattern so that the user can visually recognize it as a three-dimensional structure having a sense of depth in the real space.

  In the case of this embodiment, as shown in FIG. 3, when the user U wears the HMD part 2a on the head and visually recognizes the virtual object 8, the user U is at a position about 300 [mm] away from the user U. The display position is adjusted as if a spherical virtual object 8 having a diameter of 40 [mm] exists. Thus, the image display unit 7 can align the virtual object 8 so that the virtual object 8 is close to both palms H of the user U by extending the hand forward of the user U. An illusion as if it is placed can be given to the user U.

  In the embodiment described above, the case where the virtual object 8 is stereoscopically displayed at a position approximately 300 [mm] away from the user U has been described. However, the present invention is not limited to this, and the user U performs the HMD. When the virtual object 8 is visually recognized via the unit 2a, the virtual object 8 may be stereoscopically displayed at various positions within a distance L that allows the virtual object 8 to be aligned on the palm H of the user U.

  As shown in FIG. 4, for example, the user U forms a placement area with both palms H by bringing the little finger ball sides and little finger sides of the palm H into contact with each other, and aligns the virtual object 8 on both palms H. obtain. At this time, since the virtual object 8 is formed to be translucent, the body part (in this case, a finger) behind the virtual object 8 can be directly viewed by the user.

  In this way, the virtual object 8 allows the user U to perceive the background behind and allows the user U to visually recognize the mass of the virtual object 8 as being small, and the virtual object 8 touches the palm H. The user U can be given an image that only a weak tactile stimulus will occur.

  In addition to this, in the case of this embodiment, as shown in FIG. 4, the control unit 3 causes the image display unit 7 to move the virtual object 8 that periodically reciprocates within a predetermined range in the left-right direction. When the user U's palms H are aligned directly below the virtual object 8, the virtual object 8 is moved along the palms H while remaining close to the palms H of the user U. It is designed to give the illusion that it is moving.

  Thus, the image display unit 7 allows the user U to visually recognize a state that is floating near the palm H of the user U by some energy of the virtual object 8 itself, and the virtual object 8 itself is The user U can visually recognize the state as if he / she is moving on the palm H of the user U with intention.

  The image display unit 7 keeps giving such a visual illusion to the user U, and feels some energy generated from the virtual object 8 with the palm H in accordance with the movement of the virtual object 8. The user U can be given a tactile illusion as if he / she is.

  In the above configuration, in the see-through type HMD device 1, the image display unit 7 stereoscopically displays the translucent virtual object 8 having a stereoscopic shape in the real space where the user U exists using binocular parallax. In the space, the virtual object 8 is visually recognized by the user U as if it exists on both palms H of the user U. Further, the virtual object 8 is close to both palms H of the user U and along the palms H. The user U was made to visually recognize the situation as if he was moving.

  In this way, in the see-through type HMD device 1, the visual illusion is obtained by allowing the user U to visually recognize the state that the virtual object 8 is moving along the palm H while being close to the palm H of the user U. Based on this, it is possible to give the user U the illusion that a tactile stimulus from the virtual object 8 that is not actually given is perceived.

(2) Other Embodiments The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, in the above-described embodiment, the case where the translucent virtual object 8 capable of transmitting the back background is applied as the virtual object has been described. A virtual object with a blurred image may be applied, or a virtual object that is translucent and has a blurred outline may be applied.

  In this way, even if the outline of the virtual object is blurred and the boundary between the virtual object and the background behind it is obscured, the user can imagine that the mass of the virtual object will be small. The user can be given an image that even if touched, only a weak tactile stimulus will occur.

  In addition, when a virtual object that is translucent and has a blurred outline is applied, the user can imagine that the mass of the virtual object is much smaller, and even if the virtual object touches the palm, a weak tactile sense It is possible to give the user a further image that only stimulation will occur.

  Further, in the above-described embodiment, the case where the spherical virtual object 8 is applied as the virtual object has been described. However, the present invention is not limited thereto, and the ellipsoid, the triangular pyramid, the cone, and the rectangular parallelepiped. In addition, as long as it falls within the range of a body part such as a palm, for example, a character imitating a person or an animal, a virtual object representing an air current, or other various virtual objects may be applied.

  Furthermore, in the above-described embodiment, the case where the stereoscopic display of the virtual object 8 is changed so that the virtual object 8 moves along the palm H while being close to the palm H has been described. The present invention is not limited to this, and the virtual object 8 that remains stationary at a predetermined position may be applied without moving in the left-right direction or the like.

  In this case, in the see-through type HMD device, as shown in FIG. 5, the virtual object 8 remains close to the palm H by shaking the head to the left and right while the virtual object 8 is aligned with the palm H. The state as if moving along both palms H can be visually recognized by the user U, and thus, in the same manner as in the above-described embodiment, based on the visual illusion, it is not actually given. An illusion of tactile stimulation from the virtual object 8 can be given to the user U.

  Further, the control unit 3 recognizes the palm H of the user U in advance by a sensor (not shown), and automatically moves the stereoscopic display of the virtual object 8 so that the virtual object 8 is always aligned on the palm H. You may do it. In this case, as shown in FIG. 6, when the virtual object 8 is aligned on one palm H of the user U, for example, the control unit 3 moves the palm H in the lateral direction when the virtual object 8 is aligned. In accordance with this, the virtual object 8 is also moved laterally so as to follow the palm H with a slight delay, and the user can be given a feeling as if the virtual object 8 is always close to the palm H. Even in this case, when the virtual object 8 follows the movement of the palm H, when the palm H and the virtual object 8 are slightly displaced, the user U is generated from the virtual object 8 according to the movement. It is possible to give the user U the illusion that he / she feels the energy he / she feels with his palm H.

  Furthermore, in the above-described embodiment, the case where the palm H is applied as the body part on which the virtual object 8 is superimposed has been described, but the present invention is not limited to this, for example, the upper arm, the abdomen, the thigh, Various other body parts that can be directly observed by the user, such as the lower leg, may be applied. In this case, the control unit 3 adjusts the display position for stereoscopic display of the virtual object 8 according to the body part on which the virtual object 8 is superimposed, and the virtual object 8 that is a virtual image is present on the body part of the user U. The user U can be visually recognized as if it were.

(3) Verification Test Next, a verification test using the above-described see-through HMD device 1 will be described. Here, in order to examine an optimal stimulus presentation method for an illusion phenomenon (hereinafter referred to as a tactile illusion phenomenon) as if a tactile sensation is applied using the see-through type HMD device 1 described above, the user has an illusion. In order to investigate the characteristics of tactile stimulation and the optimal presentation method of virtual objects, the following verification test was conducted.

  In this verification test, as shown in FIG. 7, it was verified whether or not the subject had an illusion of tactile stimulation for Example 1, Example 2, Comparative Example 1 and Comparative Example 2 under different conditions. In this case, in Example 1, a semi-transparent stereoscopic virtual object is stereoscopically viewed with binocular parallax (indicated as “binocular translucent condition” in the table of FIG. 7). Although the virtual object is stereoscopically displayed using parallax, the virtual object is opaque and the contour is blurred (denoted as “binocular opacity condition” in the table of FIG. 7).

  On the other hand, in Comparative Example 1, a semitransparent virtual object having a three-dimensional shape was presented with a single eye, and a virtual object that was not stereoscopically viewed was presented (indicated as “monocular translucent condition” in the table of FIG. 7). In Comparative Example 2, a virtual object was presented on the virtual screen surface without using binocular parallax (denoted as “long distance condition” in the table of FIG. 7). In Comparative Example 2, the virtual screen position of the see-through HMD device was 24 [m], and the virtual object was presented 24 [m] ahead. The virtual object is a still image, which is created by rendering with 3DCG software (3ds Max, Autodesk).

  The virtual object presented in Example 1 is a white sphere having a diameter of 40 [mm] as shown in FIG. 2, and binocular parallax is set so that this sphere is displayed in a stereoscopic manner at a position of 300 [mm] in front of the user's eyes. did. However, in Comparative Example 1 performed under the monocular translucent condition, the virtual object was presented only to the dominant eye. Therefore, in Comparative Example 1, the position of the sphere on the screen does not change, but there is no parallax, and the sphere is displayed on the screen surface of the see-through HMD device. The optical focal position of the see-through type HMD device in Comparative Example 1 was 2.5 [m].

  In the comparative example 2 of the long distance condition in which the virtual object is presented at a long distance, the virtual object without parallax was presented based on the optical see-through condition. In Example 2 of the binocular opacity condition, as shown in FIG. 8, the rear of the sphere 8a is transmitted by adding a filter 10a with a black seal attached to the front surface of the image display unit 7 in the HMD unit 2a. Invisible virtual object 10. At this time, since the positional relationship between the sphere 8a and the filter 10a varies depending on the pupil interval of the subject and the mounting position of the HMD portion 2a, the background in a slightly wider range than the sphere 8a is shielded by the filter 10a. However, the virtual object 10 blurs the outline of the filter 10a to obscure the boundary between the filter 10a and the back background.

  The proximity of the virtual objects 8 and 10 and the body part was realized by the subject attaching the palm H directly under the virtual objects 8 and 10. Furthermore, in this verification test, since the virtual objects 8 and 10 formed of still images were used, the virtual objects 8 and 10 were shaken by having the subject shake the head with the virtual objects 8 and 10 aligned on the palm H. 10 realized an amplitude motion on the palm H from side to side.

  As the see-through type HMD device 1, an optical see-through type HMD (Moverio BT-100, EPSON) was used. A black screen is placed in front of the subject so that when the subject views the virtual objects 8 and 10, the background behind the virtual objects 8 and 10 cannot be seen, and the brightness is similar to that of general offices. I went in the room. However, in order to prevent stray light from the see-through HMD device 1, the light source directly above the subject was turned off.

  The subjects were 12 men and women (9 men, 3 women) from 21 to 39 years old. The verification test was conducted after explaining the purpose of the verification test and the data to be acquired to the subjects. In practice, the verification test was conducted in two parts, the first experiment and the second experiment. First, as the first experiment, the virtual object 8 was observed under the binocular translucent condition of Example 1, and FIG. As shown in Fig. 5, after positioning the virtual object 8 on both palms H, the virtual object 8 was moved in amplitude on both palms H by shaking his head. At this time, an interview survey was conducted on the feelings felt by the subjects.

  In the interview, the sense of hand feeling, its strength, the position to feel, the impression change when changing the speed of amplitude movement, the impression change when changing the direction of movement, the impression change due to the positional relationship between the virtual object 8 and the body part, etc. Asked questions and allowed them to answer freely.

  As a result, from the subject who saw the state in which the virtual object 8 was oscillating on the palm H, the opinion that “there was a feeling that the palm was hit by the wind” or “I felt cold on the palm” I was able to confirm the opinion, “I felt the existence and signs of things in my palm.”

  On the other hand, some subjects also expressed the opinion that "it is not the touch that an object is touching" and the opinion that "I feel something when I am told". From these opinions, there is an illusion that there is not a clear tactile stimulus such as the contact of an object with the palm H, but a very weak tactile stimulus that receives air or wind. Was confirmed.

  In addition, the opinion was obtained from the subject that the illusion that a tactile stimulus was perceived at a location where the virtual object 8 and the palm H seem to be in contact was obtained. In particular, when it appears to be floating or when it is completely crossed with a hand, the opinion that the above weak tactile stimulation does not occur is heard, and the virtual object 8 is placed on the surface of the body part. It was found that visual recognition as if they were close to each other was effective in generating an illusion phenomenon.

  Regarding the speed of the amplitude movement of the virtual object 8, there are reports that the sensation does not change even if it is made faster or slower, and there are reports that the faster feels colder, and the impression varies depending on the subject. . The subject who felt cold felt that the intensity of the illusion differed depending on the speed of the amplitude movement.

  Next, the second experiment was performed. In this second experiment, under the conditions of Example 1, Example 2, Comparative Example 1 and Comparative Example 2, the subject placed both palms H directly under the virtual objects 8 and 10, and the virtual object was shaken by shaking his head. The subject was made to visually recognize the state where 8, 10 was swinging on both palms H. In Example 1, Example 2, Comparative Example 1 and Comparative Example 2, the observation time of the virtual objects 8 and 10 that swing in amplitude on both palms H was 10 seconds. Here, each of Example 1, Example 2, Comparative Example 1 and Comparative Example 2 was evaluated by Scheffe's paired comparison method.

  After the two presentations, we asked for answers in 7 levels, -3 to +3, as to which one felt the illusion in the second condition compared to the first condition. At this time, as an illusion definition, it was explained that it was a sensation that occurred in the first part, and instead of comparing the intensity of the sensation itself, which was easier to recognize the occurrence of the illusion, it was evaluated. With the above presentation and evaluation as one set, 12 sets of trials were performed under a combination of four conditions (Example 1, Example 2, Comparative Example 1 and Comparative Example 2). After the evaluation of all trials was completed, an introspective report was also requested for the impressions felt throughout the verification test.

  For the four conditions of Example 1, Example 2, Comparative Example 1 and Comparative Example 2, the evaluation results obtained by the paired comparison method showing which conditions made it easy to recognize the occurrence of the illusion are shown in FIGS. 9A and 9B. Summarized in Here, FIG. 9A shows a psychological scale obtained with respect to the ease of occurrence of the illusion based on the evaluation value of each comparison on the coordinate axis, and FIG. 9B summarizes the coordinate values on the psychological scale. It is a table.

  From FIG. 9A and FIG. 9B, in Example 1 presenting a translucent three-dimensional virtual object 8 and Example 2 presenting an opaque virtual object 10, Example 1 is evaluated more than Example 2. it was high. However, it was found that both Example 1 and Example 2 are significantly more likely to cause illusion than other Comparative Examples 1 and 2. In other words, it can be said that Comparative Example 1 is less likely to cause an illusion than Examples 1 and 2, and Comparative Example 2 is less likely to cause an illusion than Comparative Example 1.

  One difference between Example 1 and Example 2 where illusions are likely to occur and Comparative Example 1 and Example 2 where illusions are difficult to occur is whether a virtual object could be presented at the same position as the hand by stereoscopic vision In some cases, the ability to localize the depth position by the virtual objects 8 and 10 is effective in generating the illusion phenomenon.

  Next, by changing the shape of the virtual object, the same verification test as in Example 1 was performed, and the occurrence of the illusion of tactile stimulation was examined. Specifically, when a sphere with a diameter of 40 [mm] is presented at a viewing distance of 300 [mm], a sphere with a diameter of 40 [mm] is presented at 400 [mm] with a different viewing distance, a diameter of 40 [mm] ] When a cone with a height of 40 [mm] is presented at a viewing distance of 300 [mm], a sphere with a diameter of 40 [mm] with a contour blurred by image processing is presented at a viewing distance of 300 [mm] A verification test was conducted to determine whether the subject had an illusion of tactile stimulation.

  10A shows a left-eye image 15a and a right-eye image 15b when a sphere that is a virtual object is stereoscopically displayed in real space by binocular parallax, and FIG. 10B shows both cones that are virtual objects. FIG. 10C shows the left-eye image 16a and the right-eye image 16b when stereoscopically displaying in the real space by eye parallax, and FIG. 10C shows the left eye when stereoscopically displaying the blurring sphere, which is a virtual object, in the real space by binocular parallax. The image 17a for images and the image 17b for right eyes are shown. These virtual objects are both translucent when viewed using HMD, and the left-eye images 15a, 16a, 17a and the right-eye images 15b, 16b, 17b are obtained by 3DCG software (3ds Max, Autodesk). Made by rendering.

  Similar to the verification test described above, the movement of the virtual object on the body part reproduces the amplitude movement of the virtual object by swinging the head wearing the HMD unit 2a to the left and right. Regarding the speed, the subjects were instructed “with the width of the hand” and “with their own rhythm”, and this width and speed were standard.

  Then, as subjective evaluation, “not feeling tactile sensation” was counted as 1 point, and “feeling tactile sensation” was counted as 5 points, and the result shown in FIG. 11A was obtained. FIG. 11A suggests that the shape of a semi-transparent virtual object does not greatly affect the illusion intensity. However, even with the same sphere, when the sphere is presented at a viewing distance of 300 [mm] that is easy for the subject to reach, the sphere is presented at a viewing distance of 400 [mm] that is somewhat difficult for the subject to reach. However, it was confirmed that the rating score was slightly high and it was easy to feel the illusion of tactile stimulation.

  Next, for the standard motion of a virtual object, the illusion of tactile stimulation is under the four conditions of “amplify fast”, “amplify slowly”, “amplify with a wide width”, and “amplify with a narrow width”. A verification test was conducted to see how this would be. In this verification test, a sphere with a diameter of 40 [mm] was presented at a position 300 [mm] in front of the eye. The results of these verification tests are shown in FIG. 11B. FIG. 11B suggests that changing the motion condition of the virtual object does not significantly affect the illusion intensity.

  12 and 13 summarize the free answers obtained from each subject when the above-described verification test was performed. To summarize the above, from a subject who visually recognizes that the virtual object is moving along the palm while staying close to the palm, as shown in FIG. 12, “I felt cold”, “the sphere rolled. "I felt like tickling", "I felt tickling", "I felt like a lump of air", "I felt like the wind was passing through my hands", "I felt the weight of the object" It was. It was found that the sensation of gas contact such as “coldness”, “chunk of air”, and “wind” occurred as an illusion.

  In addition, when the shape of the virtual object is a sphere, there are many opinions that “there is a feeling of rolling”, and it is considered that the tactile sensation that comes from the shape of the object is directly felt as an illusion. Similarly, under the condition that the virtual object is moved rapidly and greatly, it is thought that the wind caused by the movement is conceived and is felt as an illusion as it is. Thus, in the see-through HMD device 1, the virtual object is stereoscopically displayed so as to be superimposed on the body part in the real space, and the state in which the virtual object is moved along the body part while being in close proximity to the body part is displayed. It was confirmed that the user can be given an illusion as if a weak tactile stimulus such as a breeze is being given from the virtual object to the body part.
