Definitions
- the present invention relates to a technology that presents a physical phenomenon based on magnetic force to a user who inputs information onto a touch screen.
- Patent Documents 1 and 2 disclose technology that allows both input to a touch panel and the presentation of a force sensation.
- a first object which has south and north poles magnetized repeatedly on the same surface
- a second object which has south and north poles magnetized repeatedly on the same surface
- the user can perform input operations on the touch panel by manipulating this second object. At this time, the user perceives a force sensation based on the magnetic force between the first object and the second object.
- the force sense perceived by the user is based on the magnetic force between the first object and the second object. Therefore, the area in which the force sense can be presented to the user is limited to the area in which the first object is placed.
- the first object is placed on the input surface side of the touch panel. Therefore, when the technique of Patent Document 1 is applied to a touch screen, the user cannot see any of the content displayed in the area in which the first object is placed. This problem is common not only when a force sense is presented based on the magnetic force between the first object and the second object, but also when physical phenomena such as force sense, vibration, movement, and sound are presented based on the magnetic force between the first object and the second object.
- the present invention provides technology that can present a physical phenomenon based on magnetic force to a user who has input data onto a touch screen, while also allowing the user to visually recognize the content displayed in the area where this physical phenomenon can be presented.
- a touchscreen input system for inputting to a touchscreen has a first object and a second object.
- the first object includes a first surface, and the first surface is placed in contact with or in close proximity to a surface different from the display input surface of the touchscreen.
- the second object is placed in contact with or in close proximity to the display input surface, and includes at least one ferromagnetic part and a transparent material part.
- the position and/or attitude of the second object is changeable.
- a force in a first direction which is an attractive force or a repulsive force, is generated between a first region of the first surface of the first object that corresponds to a predetermined input position on the display input surface and the ferromagnetic part.
- a force in the first direction is not generated between a second region of the first surface of the first object that is close to the first region and the ferromagnetic part.
- a user of the touchscreen can view the display content of the display input surface through the transparent material part.

- FIG. 42 is a plan view for illustrating the configuration of a touch screen input system according to a modified example of the tenth
- an input system for a touch screen for inputting an input to a touch screen and presenting a force sense to a user is illustrated.
- the touch screen may be an electronic device or may be independent of the electronic device.
- the electronic device may be any device, for example, a smartphone terminal device, a tablet terminal device, a notebook type personal computer terminal device equipped with a touch screen, or other devices.
- the touchscreen input system of this embodiment has a first object and a second object.
- the first object includes a first surface, and the first surface is placed in contact with or in close proximity to a surface different from the display input surface of the touchscreen.
- the first object includes a ferromagnetic material such as iron, cobalt, nickel, gadolinium, etc.
- the first object may be magnetized or may not be magnetized.
- the second object is placed in contact with or in close proximity to the display input surface of the touchscreen, and includes at least one ferromagnetic material part and a transparent material part.
- the ferromagnetic material part includes a ferromagnetic material such as iron, cobalt, nickel, gadolinium, etc.
- the ferromagnetic material part may be a magnet or may not be a magnet.
- the touchscreen is interposed between the first object and the second object, and they are placed with a certain gap between them. This makes it possible to prevent the magnetism of the second object from being rewritten by the magnetic force of the first object, or the magnetism of the first object from being rewritten by the magnetic force of the second object.
- the position and/or posture of the second object is changeable. For example, the position and/or orientation of the second object relative to the first object and the touch screen can be changed.
- a force in a first direction which is an attractive force or a repulsive force, is generated between a first region of the first surface of the first object, which corresponds to a predetermined input position on the display input surface of the touch screen, and the ferromagnetic material part of the second object.
- This force is based on the magnetic force between the first surface of the first object and the ferromagnetic material part of the second object.
- a force in the first direction is not generated between a second region of the first surface of the first object, which is adjacent to the first region, and the ferromagnetic material part of the second object.
- a force in the first direction is generated or not generated between the first object and the second object depending on the positional relationship between the first object and the second object. This makes it possible to present a force sensation to the user of the touch screen.
- the user of the touchscreen can view the display content on the display input surface of the touchscreen through the transparent material portion of the second object.
- the first surface of the first object is placed in contact with or close to a surface different from the display input surface of the touchscreen.
- the first surface of the first object corresponds to an area capable of presenting a force sensation to the user.
- this first surface of the first object is not placed on the display input surface of the touchscreen. Therefore, the user can also view the content displayed in the area of the display input surface of the touchscreen capable of presenting a force sensation. Specific examples are shown below.

That is, the size of the inside of the frame 13 is slightly larger than the outer shape of the object 12. However, the frame 13 is configured to have a shape that does not interfere with the operation (described later) of the object 12 placed inside the frame 13. It is desirable that the frame 13 includes a transparent material or a material having translucency. There is no limitation on the material of the frame 13, and it is desirable that the opposite side of the frame 13 can be seen through the frame 13. Examples of materials for the frame 13 include plastic, glass, etc.

- the surface 1213-1 of the ferromagnetic part 121-1 is magnetized to the S pole
- the area 111-1 of the plate surface 113 of the object 11 is magnetized to the N pole. Therefore, in the posture A, an attractive force (force in the first direction) is generated between the ferromagnetic part 121-1 and the area 111-1 (first area) of the plate surface 113 (first surface) of the object 11 (first object) that corresponds to the input position 1511-1 of the display input surface 151.

Therefore, in the posture B, an attractive force (force in the first direction) is generated between the ferromagnetic part 121-1 and the area 111-2 (first area) of the plate surface 113 (first surface) of the object 11 (first object) that corresponds to the input position 1511-2 of the display input surface 151.
- an attractive force force in the first direction

It is desirable that the surface 6213-2 is arranged on the same plane or approximately on the same plane as the plate surface 223-2, but these do not necessarily have to be arranged on the same plane or approximately on the same plane.
- At least a portion of the surface of the ferromagnetic material part 621-2 in this embodiment is a conductor.
- the conductor of the ferromagnetic part 621-2 is located at least on the surfaces of the faces 6213-2 and 6214-2, and electrically connects the faces 6213-2 and 6214-2. Furthermore, the conductor located on the surface of the face 6214-2 is in contact with the conductor 625, and is electrically connected.
- the ferromagnetic part 621-2 is, for example, cylindrical, but this does not limit the present invention, and it may be a prismatic shape or another shape.
- the transparent material section 622-2 includes a transparent material or a material having transparency. This allows the user U to view the display content of the display input surface 151 through the transparent material section 622-2 when the object 62 is placed in contact with or in close proximity to the display input surface 151 of the touch screen 15.
- the base portion 620-1 is, for example, a transparent material portion that includes a transparent material or a material having transparency. This allows the user U to view the display content of the display input surface 151 through the base portion 620-1 (transparent material portion) when the object 62 is placed in contact with or close to the display input surface 151 of the touch screen 15.
- the entire base portion 620-1 may be made of a transparent material or a material having transparency, or a portion of the base portion 620-1 may be made of a transparent material or a material having transparency. However, this does not limit the present invention, and the base portion 620-1 does not have to be transparent.
- an object 61 is placed on the surface 152 side of the touch screen 15. At this time, a plate surface 613 of the object 61 is in contact with or close to the surface 152 of the touch screen 15.
- An object 62 is placed on the display input surface 151 of the touch screen 15. The object 62 is placed, for example, in contact with the display input surface 151 of the touch screen 15. In this embodiment, the plate surfaces 623-1 and 623-2 of the object 62 are placed in contact with the display input surface 151. However, this does not limit the present invention, and a member such as a thin sheet may be interposed between the object 62 and the display input surface 151.
- the plate surfaces 623-1 and 623-2 of the object 62 may be placed close to the display input surface 151. That is, the surface of the base part 620-1 arranged on the display input surface 151 side is a plate surface 623-1 (third partial surface), and the surface of the movable part 620-2 arranged on the display input surface 151 side is a plate surface 623-2 (fourth partial surface).
- the object 62 arranged on the display input surface 151 in this manner can slide in the D61 and D62 directions (FIG. 22A).
- the D61 direction is a specific direction parallel to the display input surface 151.
- the D62 direction is a direction perpendicular to the D61 direction and parallel to the display input surface 151.
- an example is shown in which the D61 direction is the left-right direction in FIG. 22A and the D62 direction is the up-down direction in FIG. 22A.
- This sliding can change the relative position of the object 62 with respect to the object 61 and the display input surface 151.
- the plate surface 613 of the object 61 is magnetized in advance with the N-pole region 611 and the S-pole region 612 repeatedly.
- the surface 6213-2 of the ferromagnetic part 621-2 of the movable part 620-2 is magnetized to the N-pole.
- a reference state A e.g., FIG. 24B
- the surface 6213-2 (north pole) of the ferromagnetic part 621-2 of the movable part 620-2 is positioned toward the region 612 (south pole) of the object 61
- there is also a rotation state B e.g., FIGS. 25A and 25B
- an attractive force force in the first direction
- an area 612 spaced apart from the plate surface 613 that corresponds to the input position 1511 of the display input surface 151 and the ferromagnetic part 621-2 (surface 6213-2 (north pole)) of the movable part 620-2. Therefore, the plate surface 623-1 of the base part 620-1 and the plate surface 623-2 of the movable part 620-2 are in contact with or close to the display input surface 151.
- a repulsive force (force in the first direction) is generated between an area 611 (N pole) of the plate surface 613 of the object 61 that corresponds to the input position 1511 of the display input surface 151, and the ferromagnetic part 621-2 (surface 6213-2 (N pole)) of the movable part 620-2. Therefore, the movable part 620-2 rotates (rotates in the R6 rotation direction) relative to the base part 620-1, and the plate surface 623-2 is farther away from the display input surface 151 than in the reference state A.
- the user U can touch the plate surface 624-1 side (conductor 625) of the base part 620-1 of the object 62 with a body part such as a finger, and slide the object 62 in the D61 direction and the D62 direction (FIGS. 24B to 27D).
- the above-mentioned reference state A and rotation state B are repeated depending on the relative position of the object 62 with respect to the object 61.
- the reference state A in which the movable part 620-2 receives an attractive force from the object 61 and the rotation state B in which the movable part 620-2 receives a repulsive force are repeated.
- the user U who is touching the base part 620-1 connected to the movable part 620-2, perceives a force sense and vibration associated with this sliding operation.
- the user U visually perceives the movement in which the movable part 620-2 repeats the reference state A in which it is not rotating and the rotation state B in which it is rotating.
- the plate surface 623-2 of the movable part 620-2 hits the display input surface 151, generating a sound.
- the user U also perceives this sound. In this way, the user U can perceive physical phenomena such as force sensation, vibration, movement, and sound caused by the repetition of the reference state A and the rotation state B.
- the touchscreen input system 60 of this embodiment is configured so that when the object 62 is brought into the reference state A by the slide operation of the user U, the conductor of the movable part 620-2 (the conductor of the ferromagnetic part 621-2) comes into contact with or approaches the input position 1511.
- the touchscreen input system 60 not only presents the physical phenomenon accompanying the slide operation as described above to the user U, but can also perform an input operation to the touchscreen 15 in response to the slide operation. That is, the slide operation of the object 62 described above is performed in a state in which the user U touches the conductor 625 of the plate surface 624-1 of the base part 620-1.
- the conductor 625 is electrically connected to the conductor on the surface of the face 6214-2 of the ferromagnetic part 621-2, and further, the conductor on the surface of the face 6214-2 is also electrically connected to the conductor on the surface of the face 6213-2. Therefore, when the user U performs a slide operation while touching the conductor 625, an input is made to the input position 1511 of the display input surface 151 facing the surface 6213-2 of the ferromagnetic part 621-2 in the reference state A (FIG. 24B).
- the conductor of the movable part 620-2 (the conductor of the ferromagnetic part 621-2) is farther away from the input position 1511 than when it is in the reference state A. Therefore, no input is made to the display input surface 151 in the rotation state B (FIGS. 25A and 25B). Therefore, the reference state A in which an input is made to the display input surface 151 and the rotation state B in which no input is made are repeated by the slide operation, and it is possible to make a discrete input in time. This input interval can be adjusted by the sliding speed of the object 62 relative to the display input surface 151.
- the content displayed on the display input surface 151 of the touch screen 15 changes according to the slide operation by the user U.
- the user U is not touching the object 62 (conductor 625) and no slide operation is being performed, no display is performed on the display input surface 151 (FIGS. 25A, 26A, 27A).
- this does not limit the present invention, and when no slide operation is being performed, the display content displayed in the initial state or the display content displayed during the previous slide operation may be displayed on the display input surface 151.
- display content 650 displayed on display input surface 151 changes accordingly. That is, in reference state A, input is made to input position 1511 on display input surface 151 facing surface 6213-2 of ferromagnetic part 621-2. At this time, display content 650 is displayed at input position 1511 on display input surface 151 and around it. Input position 151 changes according to the relative position of object 62 with respect to display input surface 151. Therefore, the display position of display content 650 also changes according to the slide operation (FIG. 26B to FIG. 26D, FIG. 27B to FIG. 27D).
- At least a part of the movable part 620-2 of the object 62 is a conductor.
- the content displayed around said input position 1511 on the display input surface 151 is different from the content displayed around a position on the display input surface 151 where this conductor is not in contact with or close to it.
- the content displayed around the input position 1511 on the display input surface when the conductor of the object 22 is in contact with or close to the input position 1511 due to the operation of the user U is different from the content displayed around a position on the display input surface 1511 where this trigger does not occur.

A frame portion 23 is placed on the display input surface 151 of the touch screen 15, and an object 62 is placed inside the frame portion 23. This frame portion 23 positions the object 62 so that it can slide in the D2 direction along the reference line LR on the display input surface 151 side.
- the object 21 and the object 62 are placed such that the reference line LR on the display input surface 151 is placed along the line L1 of the object 21, and in the reference state A, the plate surface 623-1 (third partial surface) and the plate surface 623-2 (fourth partial surface) are located on or near the reference line LR, and in the rotation state B, the plate surface 623-1 is located on or near the reference line LR. 25A and 25B, in rotation state B, plate surface 623-1 is farther away from display input surface 151 than in reference state A.
- a member such as a thin sheet may be interposed between object 62 and display input surface 151.
- the object 62 thus arranged on the display input surface 151 can slide in the direction D61 along the reference line LR. This sliding can change the relative position of the object 62 with respect to the object 21 and the display input surface 151.
- the plate surface 213 of the object 21 is magnetized in advance with N-pole regions 211 and S-pole regions 212 repeatedly magnetized along the line L1 (FIG. 6A).
- the surface 6213-2 of the ferromagnetic part 621-2 of the movable part 620-2 is magnetized to the N-pole.
- User U can touch the plate surface 624-1 side (conductor 625) of the base portion 620-1 of the object 62 with a body part such as a finger, and slide the object 62 in the direction D61.
- the above-mentioned reference state A and rotation state B are repeated depending on the relative position of the object 62 with respect to the object 21.
- This causes the reference state A, in which the movable portion 620-2 receives an attractive force from the object 21, and the rotation state B, in which it receives a repulsive force, to be repeated.
- the user U can touch the plate surface 624-1 side (conductor 625) of the base portion 620-1 of the object 62 with a body part such as a finger, and slide the object 62 in the direction D61.

- the user U can perceive physical phenomena such as force sensation, vibration, movement, and sound.
- the touch screen input system 60' not only presents the user U with the physical phenomenon associated with the slide operation as described above, but can also perform an input operation to the touch screen 15 in response to the slide operation (the operation of sliding a slider to set a parameter to a desired value, i.e., a slide input operation). That is, when the user U performs a slide operation while touching the conductor 625, an input is made to the input position 1511 of the display input surface 151 facing the surface 6213-2 of the ferromagnetic part 621-2 in the reference state A. On the other hand, in the rotation state B, no input is made to the display input surface 151.
- the content displayed on the display input surface 151 of the touch screen 15 changes in response to a slide operation by the user U.
- the display content 250-1 displayed when the user U is not touching the object 62 (conductor 625) and no slide operation is being performed can be visually distinguished from the display content 250-2 displayed when the user U is touching the object 62 (conductor 625) by the visual element ⁇ (e.g., a pattern).

- the frequency of the alternating current is, for example, about 15 Hz to 40 kHz. However, this does not limit the present invention.
- ⁇ Layout configuration> As illustrated in Fig. 30A to Fig. 31B, an object 61 is placed on the surface 152 side of the touch screen 15. At this time, a plate surface 613 of the object 61 is in contact with or close to the surface 152 of the touch screen 15.
- An object 72 is placed on the display input surface 151 of the touch screen 15.
- the object 72 is placed, for example, in contact with the display input surface 151 of the touch screen 15.
- a plate surface 7223 of a housing 722 of the object 72 is placed in contact with the display input surface 151.
- a member such as a thin sheet may be interposed between the object 72 and the display input surface 151.
- the plate surface 7223 of the object 72 may be placed close to the display input surface 151.
- the position and posture of the object 72 arranged on the display input surface 151 can be changed. That is, the object 72 can slide in the D71 direction and D72. The object 72 can also be rotated on the display input surface 151 to change the orientation of the object 72 or to change its direction of rotation.
- the D71 direction is a specific direction parallel to the display input surface 151.
- the D72 direction is a direction perpendicular to the D71 direction and parallel to the display input surface 151.
- the D71 direction is the left-right direction in FIG. 30A and the D72 direction is the up-down direction in FIG. 30A.
- This sliding can change the relative position of the object 72 with respect to the object 61 and the display input surface 151.
- the plate surface 613 of the object 61 has N-pole regions 611 and S-pole regions 612 repeatedly magnetized in advance (FIGS. 23A and 23B). Furthermore, surface 7213 of magnet 721 of object 72 is magnetized to the north pole.
- surface 7213 (north pole) of magnet 721 of object 72 is positioned toward region 612 (south pole) of object 61
- surface 7213 is positioned toward region 611 (north pole) of object 61.
- an attractive force is generated between an area 612 (south pole) of the plate surface 613 of the object 61 that corresponds to the input position 1511 of the display input surface 151 and the magnet 721 (surface 7213 (north pole)).
- no attractive force is generated between an area 611 (north pole) of the plate surface 613 of the object 61 that is close to the area 612 (south pole) and the magnet 721 (surface 7213 (north pole)), but a repulsive force is generated instead.
- the control device 73 can apply an alternating current to the coil 723.
- the alternating current applied to the coil 723 can be changed, for example, whether or not there is an alternating current and/or the magnitude of the alternating current.
- a force in the direction D73 is applied to the magnet 721 due to the reaction of the Lorentz force described by Fleming's left-hand rule (FIGS. 31B and 32).
- the D73 direction is the depth direction of the magnet insertion hole 7220 around which the coil 723 is wound.
- the D73 direction is a direction perpendicular or approximately perpendicular to the display input surface 151 when the object 72 is placed on the display input surface 151.
- a force may be applied in the direction D73 in which the magnet 721 moves away from the plate surface 7223, or a force may be applied in which the magnet 721 moves closer to the plate surface 7223. That is, when an alternating current is applied to the coil 723, the magnet 721 vibrates in the direction D73 relative to the coil 723 and the housing 722 to which it is fixed. The presence or absence and magnitude of this vibration can be controlled by the presence or absence and magnitude of the alternating current applied to the coil 723.

At this time, it is preferable that the user U slides the object 72 in a state where the user U touches not only the surface 7214 of the magnet 721 but also the end 7222 on the opening end 7224 side of the housing 722 (FIG. 31B). If the body part touches only the magnet 721, there is a risk that the above-mentioned vibration of the magnet 721 will be suppressed or stopped when a force is applied to the magnet 721 to slide the object 72. In other words, the user U can sufficiently vibrate the magnet 721 by sliding the object 72 in a state where the user U touches the magnet 721 and the housing 722.
- the magnet 721 vibrates in the direction D73 by applying an alternating current to the coil 723 by the control device 73.
- the user U touching the magnet 721 perceives a force sense (tactile stimulation) based on this vibration.
- the object 72 is stationary relative to the object 61
- the user U can be made to perceive this force sense. That is, in this embodiment, even if the user U who has input to the touch screen 15 does not change the position or orientation of the object 72 (second object) relative to the object (first object), the user U can be presented with a force sense based on magnetic force.
- the magnitude and manner of the force sense (e.g., continuous force sense, intermittent force sense, striking force sense, etc.) that the user U perceives based on the vibration of the magnet 721 can be controlled by the presence or absence and/or magnitude of the alternating current applied to the coil 723.
- the magnitude of the force sense that the user U perceives based on the vibration of the magnet 721 is greater than the magnitude of the force sense that the user U perceives based on the magnetic force between the object 72 and the object 61.
- the touch screen input system 70 of this embodiment is configured so that the conductor of the object 72 comes into contact with or approaches the input position 1511 of the display input surface 151 of the touch screen 15 when the user U operates it.
- the touch screen input system 20 can not only present the force sensation associated with the slide operation to the user U as described above, but also perform an input operation to the touch screen 15 in response to the slide operation. That is, the slide operation of the object 72 described above is performed in a state in which the user U touches the conductor located on the surface 7214 of the magnet 721.
- the ends of the movable parts, which are the magnet 721 and the elastic body 724, that are located on the display input surface 151 side are electrically conductive to the ends of the movable parts that are located on the opposite side to the display input surface 151.
- the conductor located on the surface 7214 of the magnet 721 is electrically conductive to the conductor at one end 7241 of the elastic body 724.
- the ends of the movable parts, which are the magnet 721 and the elastic body 724, arranged on the display input surface 151 side are electrically connected to the plate surface 7223 of the housing 722.
- one end 7241 of the elastic body 724 is electrically connected to the conductor on the plate surface 7223 of the housing 722.
- the content displayed on the display input surface 151 of the touch screen 15 changes according to the slide operation by the user U. For example, when the user U is not touching the object 72 (the above-mentioned conductor) and no operation is being performed, no display is performed on the display input surface 151 (FIG. 31A). On the other hand, when the user U touches the object 72 (the above-mentioned conductor), the display content 750 is displayed at the input position 1511 of the display input surface 151 and around it (FIGS. 31B and 32).
- the object 72 is a conductor, and when a conductor is in contact with or close to the input position 151 of the display input surface 151, the content displayed around the input position 1511 is different from the content displayed around the position of the display input surface 151 where the conductor is not in contact or close.
- the content displayed around the input position 151 triggered by the conductor coming into contact with or close to the input position 151 of the display input surface 151 may be different from the content displayed around the position of the display input surface 151 where the conductor is not in contact or close.
- the display content displayed when the user U is not touching the object 72 may be visually distinguishable from the display content displayed when the user U is touching the object 72 (the above-mentioned conductor) by a visual element ⁇ (e.g., a pattern).

That is, in this modified example, the physical phenomenon based on magnetic force presented to the user U who has input to the touchscreen 15 can be dynamically changed.
- an autonomous touch screen input system that autonomously moves on the touch screen and inputs data to the touch screen is exemplified. That is, in this embodiment, a user U can input data to the touch screen without touching an object.
- the touchscreen input system of this embodiment moves a second object on the touchscreen, inputs data to the touchscreen, and displays data on the touchscreen.
- This touchscreen input system includes a first object and a second object.
- the first object includes a first surface magnetized with a predetermined magnetic pattern, and the first surface is placed in contact with or in close proximity to a surface different from the display input surface of the touchscreen.
- the second object is placed in contact with or in close proximity to the display input surface, and includes at least one electromagnet, so that input to the touchscreen is performed by a portion of the second object in contact with or in close proximity to the display input surface.
- the second object moves while in contact with or in close proximity to the display input surface due to a magnetic force generated between the electromagnet generated by the application of a current to the electromagnet and the first surface magnetized with a magnetic pattern, and the position where the second object performs input to the display input surface is displaced based on the movement, and the display content of the display input surface changes based on the displacement.
- a specific example is shown below.
- ⁇ Autonomous touch screen input system 90> 34A, 34B, 37A to 37C show an example of a touch screen input system 90 according to this embodiment.
- the touch screen input system 90 in this example is an input interface for autonomously moving and inputting to the touch screen 15, and has an object 41 (first object) and an object 82 (second object).
- an object 41 is placed on the surface 152 side of the touch screen 15. At this time, the plate surface 413 of the object 41 is in contact with or close to the surface 152 of the touch screen 15.
- An object 82 is placed on the display input surface 151 of the touch screen 15. Here, the object 82 is placed, for example, in contact with the display input surface 151 of the touch screen 15.
- an end 8223 of the housing 822 of the object 82 and a surface 8213 of the ferromagnetic part 821 are placed in contact with the display input surface 151.
- a member such as a thin sheet may be interposed between the object 82 and the display input surface 151.
- the end 8223 and the surface 8213 of the object 82 may be placed close to the display input surface 151.
- Input to the touch screen 15 is performed by a portion of the object 82 that is in contact with or in close proximity to the display input surface 151. That is, a conductor is disposed on the surface 8213 of the ferromagnetic portion 821 of the object 82, and input is performed to the input position 1511 of the display input surface 1511 that is in contact with or in close proximity to the conductor. In this embodiment, input is performed to the input position 1511 using the technology described in References 1 and 2, etc. At this time, display content 850 is displayed at the input position 1511 of the display input surface 1511 and its surroundings.
- the object 82 is a conductor, and when the conductor is in contact with or in close proximity to the input position 151 of the display input surface 151, the content displayed around the input position 1511 is different from the content displayed around the position of the display input surface 151 where the conductor is not in contact with or in close proximity.
- the content displayed around input position 151 on display input surface 151 when the conductor comes into contact with or into close proximity to the input position 151 may be different from the content displayed around a position on display input surface 151 when no such trigger occurs.
- state A is not stable, and a force that tries to move to state B (a force that tries to move object 82 to a position corresponding to region 411) is applied from object 41 to object 82.
- This force is a force in the direction D911 along display input surface 151, from region 412 to region 411 ( Figure 37A).
- This force causes the object 82 to move autonomously in the direction D911, resulting in a state B in which the surface 8213 (south pole) of the ferromagnetic part 821 is disposed toward the region 411 (north pole) of the object 41 (FIG. 37B).
- the object 82 (second object) moves while in contact with or close to the display input surface 151 due to the magnetic force generated between the ferromagnetic part 821 (electromagnet generated by application of a current to the electromagnet) generated by the application of this current and the plate surface 413 (first surface) on which the magnetic pattern is magnetized. Based on this movement, the input position 1511 at which the object 82 (second object) inputs to the display input surface 151 is displaced (FIGS. 37A and 37B). In this way, the object 82 moves autonomously and inputs to the touch screen 15.
- Whether or not the object 82 moves can be controlled by whether or not to pass a current (direct current) through the coil 823.
- a current direct current
- the movement speed of the object 82 can be controlled by the magnitude of the current passed through the coil 823.
- the larger the current passed through the coil 823 the larger the above-mentioned force becomes and the faster the object 82 moves.
- the direction of movement of the object 82 can be controlled by the direction of the current passed through the coil 823.
- the display content 850 displayed at and around the input position 1511 is also displaced.
- the visual element ⁇ (pattern, etc.) of the display content 850 may change according to the input position 1511.
- state B is not stable, and a force that tries to move to state A (a force that tries to move object 82 to a position corresponding to region 412) is applied from object 41 to object 82.
- This force is a force in the D911 direction or D912 direction from the region 411 side to the region 412 side along the display input surface 151.
- This force causes the object 82 to move autonomously in the D911 direction or D912 direction, resulting in state A in which the surface 8213 (N pole) of the ferromagnetic part 821 is disposed toward the region 412 (S pole) of the object 41.
- the object 82 (second object) moves while being in contact with or close to the display input surface 151 due to a magnetic force generated between the ferromagnetic part 821 (electromagnet generated by application of a current to the electromagnet) generated by the application of this current and the plate surface 413 (first surface) on which the magnetic pattern is magnetized. Based on this movement, the input position 1511 at which the object 82 (second object) performs input to the display input surface 151 is displaced. In this way, the object 82 moves autonomously and inputs to the touch screen 15.
- the movement of the object 82 can be controlled by whether or not a current (DC) is passed through the coil 823. In other words, when no current is passed through the coil 823, the above-mentioned force is not generated and the object 82 does not move.
- the movement speed of the object 82 can be controlled by the magnitude of the current passed through the coil 823. In other words, the larger the current passed through the coil 823, the larger the above-mentioned force becomes and the faster the movement speed of the object 82 becomes.
- the direction of movement of the object 82 can be controlled by the direction of the current passed through the coil 823.
- the display content 850 displayed at and around the input position 1511 is also displaced.
- the visual element ⁇ (pattern, etc.) of the display content 850 may change according to the input position 1511.
- the object 82 may further include a transparent material portion (an object made of a transparent material or a material having transparency), and when the object 82 is placed in contact with or in close proximity to the display input surface 151 of the touch screen, the user U of the touch screen 15 may be able to view the display content of the display input surface 151 through the transparent material portion.

Specific examples are shown below.
- ⁇ Linear motor type touch screen input system 100> 38A to 41B show an example of the touch screen input system 100 of this embodiment.

That is, the object 102 of this embodiment is, for example, two objects 82 described in the eighth embodiment that are connected (fixed). These two objects 82 are denoted as objects 82-1 and 82-2.
- the magnetic material part 821, the housing 822, and the coil 823 of the object 82-1 are denoted as the magnetic material part 821-1, the housing 822-1, and the coil 823-1, respectively.

- the denotations of the other parts constituting the objects 82-1 and 82-2 are similar.
- These objects 82-1, 82-2 (multiple electromagnets) are arranged so that one pole of each of the objects 82-1, 82-2 (electromagnets) is in contact with or close to the display input surface 151.

These surfaces 8213-1, 8213-2 are arranged so that they are in contact with or close to the display input surface 151.
- a current can be applied independently to the poles of each of the objects 82-1, 82-2 (electromagnets) so that they become either an N pole, an S pole, or neither.
- the coils 823-1 and 823-2 are configured to be applied with currents independently controlled by the control device 103.
- the control device 103 can independently control whether or not to apply currents to the coils 823-1 and 823-2, and the direction and magnitude of the currents to be applied for the coils 823-1 and 823-2.
- the distance between the surfaces 8213-1 and 8213-2 of the ferromagnetic parts 821-1 and 821-2 of the object 102 is different from the distance between the regions 611 and 612 of the object 61. This is because, even if the object 102 is stationary relative to the object 61, the moving direction of the object 102 can be controlled simply by controlling the currents to be applied to the coils 823-1 and 823-2.
- an object 61 is placed on the surface 152 side of the touch screen 15. At this time, the plate surface 613 of the object 61 is in contact with or close to the surface 152 of the touch screen 15.

In this embodiment, input is performed to the input position 1511 using the technology described in References 1, 2, etc. At this time, the display content 1050 is displayed at the input position 1511 of the display input surface 1511 and its surroundings.
- the object 102 is a conductor, and when the conductor is in contact with or in close proximity to the input position 151 of the display input surface 151, the content displayed around the input position 1511 is different from the content displayed around the position of the display input surface 151 where the conductor is not in contact with or in close proximity.

That is, in this embodiment, the object 102 can be moved in the D1011 direction and the opposite direction (collectively referred to as the D101 direction).

図1Aから図3Bに、ロッカースイッチ(シーソースイッチと呼ばれることもある)として機能するタッチスクリーン用入力システム10を例示する。図1Aおよび図1Bに例示するように、この例のタッチスクリーン用入力システム10は、タッチスクリーン15への入力と力覚の呈示とを行うための入力インタフェースであり、オブジェクト11(第1オブジェクト)とオブジェクト12(第2オブジェクト)と枠部13とを有する。
図1B、図3Aおよび図3Bに例示するように、この例のオブジェクト11は、板面113(第1面)を含み、板面113がタッチスクリーン15の表示入力面151とは異なる面152に接触または近接して配置されるように構成されている。この例の面152は、表示入力面151の反対側の面である。オブジェクト11は、例えば、強磁性体を含む磁性シートである。しかし、必ずしもオブジェクト11がシート状である必要はなく、立方体や直方体等のその他の形状であってもよい。図2に例示するように、オブジェクト11の板面113の2つの領域111-1,領域111-2(第1領域)はN極に着磁されており、この領域111-1,111-2と異なる板面113の領域112(第2領域)はS極に着磁されている。この例では、領域111-1,111-2と領域112とは互いに近接している。しかし、領域111-1,111-2と領域112とが互いに離れていてもよい。また、ここでは領域111-1,111-2の辺縁部が円形である例を示すが、これは本発明を限定するものではなく、領域111-1,111-2の辺縁部が四角形や三角形等のその他の形状であってもよい。また領域111-1,111-2,112は、例えば、ネオジム磁石等でオブジェクト11の表面をなぞることで予め着磁されたものであってもよいし、その他の手法で予め着磁されたものであってもよい(以降の実施形態およびその変形例のオブジェクトも同様)。
図1B、図3Aおよび図3Bに例示するように、この例のオブジェクト12は、支点123を介した板状部分120-1(第1部分)と板状部分120-2(第2部分)とを含むシーソー構造(略L字板構造)を含む。この例の板状部分120-1,120-2は四角板状であり、それぞれの一端が互いにつながっている。ただし、これは本発明を限定するものではなく、板状部分120-1,120-2が四角板状以外の形状であってもよい。ここで、板状部分120-1の一方の板面123-1と板状部分120-2の一方の板面123-2とは互いに同じ側に配置されている。また、板状部分120-1の他方の板面124-1と板状部分120-2の他方の板面124-2とは、ともに板面123-1および板面123-2の反対側に配置されている。また、板面123-1の端部が板面123-2の端部とつながり、板面124-1の端部が板面124-2の端部とつながっている。ただし、板面123-1と板面123-2とは同一平面上に配置されておらず、これらは互いに一定の角度θ1を持っている。同様に、板面124-1と板面124-2とは同一平面上に配置されておらず、これらは一定の角度θ2を持っている。すなわち、板状部分120-1と板状部分120-2とが正面視で略V字型となるようにつながっている(図1B、図3Aおよび図3B)。なお、板面124-1と板面124-2が押しやすいよう略V字型の折れ角は鈍角であることが望ましい。すなわち、図3Aに例示するように0°<θ1,θ2≦90°であり、例えば、3°<θ1,θ2≦90°である。板面123-1と板面123-2との境界は線分状の角(山型のコーナー)であり、この線分状の境界が支点123である。
図1B、図3Aおよび図3Bに例示するように、この例の枠部13は矩形枠状の部材であり、その内側にオブジェクト12を位置決め可能な形状に構成されている。すなわち、枠部13の内側の大きさはオブジェクト12の外形よりも若干大きい。ただし、枠部13は、その内側に配置されたオブジェクト12の動作(後述)を妨げない形状に構成されている。枠部13は、透明素材または透過性を持つ素材を含むことが望ましい。枠部13の材質に限定はなく、枠部13を介して当該枠部13の反対側が視認可能であることが望ましい。枠部13の材質の例は、プラスチック、ガラス等である。
図1A等に例示するように、タッチスクリーン15の面152側にオブジェクト11が配置される。この際、オブジェクト11の板面113が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151には枠部13が配置され、枠部13の内側にはオブジェクト12が配置される。この枠部13によって、オブジェクト12が表示入力面151側の所定の場所に位置決めされる。ただし、これらは、枠部13が後述するオブジェクト12の動作を妨げないよう配置される。オブジェクト12は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト12の支点123が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト12と表示入力面151との間に薄いシート等の部材が介在してもよい。すなわち、オブジェクト12が、表示入力面151に近接して配置されてもよい。例えば、オブジェクト12の支点123が表示入力面151に近接して配置されるよう構成されていてもよい。このようにオブジェクト12の支点123が表示入力面151に接触または近接して配置された際、板状部分120-1(第1部分)の表示入力面151側に配置される面が板面123-1(第1部分面)であり、板状部分120-2(第2部分)の表示入力面151側に配置される面が板面123-2(第2部分面)である。
タッチスクリーン15の利用者Uは、オブジェクト12の板面124-1または板面124-2の何れかを指等の身体部位でオブジェクト11側へ押し下げ、これによってオブジェクト12を、支点123を中心にR1回転方向に回動させ、姿勢A(図3A)または姿勢B(図3B)の何れか一方を選択できる。姿勢Aでは領域111-1と面1213-1との間で吸引力が発生している。そのため、姿勢Aで利用者Uが板面124-2を押し下げると、利用者Uは領域111-1と面1213-1との間の吸引力に基づく反力を知覚する。板面124-2への押し下げ力がこの反力を超えると姿勢Bになる。姿勢Bでは領域111-2と面1213-2との間で吸引力が発生している。そのため、姿勢Bで利用者Uが板面124-1を押し下げると、利用者Uは領域111-2と面1213-2との間の吸引力に基づく反力を知覚する。板面124-1への押し下げ力がこの反力を超えると姿勢Aになる。言い換えると、オブジェクト12が姿勢Aのときに強磁性体部121-1の面1213-1が向いている板面113(第1面)の領域111-1と、面1213-1との間の磁力は、オブジェクト12が姿勢Bのときにはオブジェクト12の姿勢を変化させないが、オブジェクト12が姿勢Bから遠ざけられて姿勢Aに近づけられるように、オブジェクト12が利用者Uによって操作されたとき、領域111-1と面1213-1との間の吸引力でオブジェクト12が姿勢Aとなる関係にある。また、オブジェクト12が姿勢Bのときに強磁性体部121-2の面1213-2が向いている板面113(第1面)の領域111-2と、面1213-2との間の磁力は、オブジェクト12が姿勢Aのときにはオブジェクト12の姿勢を変化させないが、オブジェクト12が姿勢Aから遠ざけられて姿勢Bに近づけられるように、オブジェクト12が利用者Uによって操作されたとき、領域111-2と面1213-2との間の吸引力でオブジェクト12が姿勢Bとなる関係にある。これにより、姿勢Aと姿勢Bの2つの状態に切り替え可能なロッカースイッチの力覚を利用者Uに呈示できる。切り替えられる2つの状態は、例えば、ON状態とOFF状態であってもよいし、2つの異なるON状態であってもよい。
次に、図1A,図1B,図2,図4A,図4Bに、ボタンとして機能するタッチスクリーン用入力システム10’を例示する。前述のロッカースイッチとして機能するタッチスクリーン用入力システム10との相違点は、オブジェクト12の強磁性体部121-1の磁極のみである。すなわち、図4Aおよび図4Bに例示するように、タッチスクリーン用入力システム10’の場合、強磁性体部121-1の板面123-1側の面1213-1はN極に着磁されており、板面124-1側の面1214-1はS極に着磁されている。
利用者Uがオブジェクト12に触れていないとき、オブジェクト12は姿勢Bとなる(図4B)。これは、オブジェクト12の強磁性体部121-2の面1213-2(S極)とオブジェクト11の領域111-2(N極)との間では吸引力が生じているが、オブジェクト12の強磁性体部121-1の面1213-1(N極)とオブジェクト11の領域111-2(N極)との間では反発力が生じているからである。
第1実施形態で説明したS極とN極とが反転していてもよい。すなわち、第1実施形態でS極であったすべての部分(例えば、図3Aの面1213-1)がN極であり、第1実施形態でN極であったすべての部分(例えば、図3Aの領域111-1)がS極であってもよい。
第1実施形態およびその変形例1では、強磁性体部121-1の導電体が面1213-1と面1214-1に位置し、これらが電気的に導通しており、強磁性体部121-2の導電体が面1213-2と面1214-2に位置し、これらが電気的に導通している例を示した。

また、第1実施形態およびその変形例1,2では、強磁性体部121-1の表面の少なくとも一部および強磁性体部121-2の表面の少なくとも一部が導電体であった。しかし、導電体が板状部分120-1の板面123-1と板面124-1に位置し、これらを電気的に導通させているのであれば、強磁性体部121-1の表面が導電体でなくてもよい。同様に、板状部分120-2の板面123-2と板面124-2に導電体が位置し、これらを電気的に導通させているのであれば、強磁性体部121-2の表面が導電体でなくてもよい。このような場合であっても、利用者Uがその導電体にふれた状態で板面124-1または板面124-2への押し下げ操作を行えば、前述したように入力位置1511-1または入力位置1511-2への入力を行うことができる。
第1実施形態およびその変形例1から3では、オブジェクト12が支点123を中心に2つの回転方向の何れかに回動し、姿勢Aと姿勢Bの何れかとなる例を示した。しかしながら、これは本発明を限定するものではない。例えば、第2オブジェクトが支点を中心に3つ以上の回転方向の何れかに回動し、第2オブジェクトが、第1オブジェクトおよびタッチスクリーン15に対して、3以上の姿勢に変化可能であってもよい。これにより、3以上の状態に切り替え可能なロッカースイッチやボタンの入力と力覚の呈示とを実現できる。
第2実施形態では、スライド操作によってタッチスクリーンへの入力を行うスライダー型のタッチスクリーン用入力システムを例示する。このスライダー型のタッチスクリーン用入力システムは、スライド操作によるパラメータの入力と、利用者への力覚の呈示を可能にする。このようなスライダー型のタッチスクリーン用入力システムは、例えば、所定の最小値と最大値の間の範囲内で自由に設定可能とされているパラメータ値を利用者が所望の値に設定する際の操作に用いられる入力インタフェースである。利用者は、例えば、スライダーをスライドする(所定の軸方向に動かす)操作(スライド操作)によって、スピーカから出力する音のボリュームや照明の明るさ等を操作できる。以降、これまで説明した事項と共通する部分については、同じ参照番号を引用し、説明を簡略化する。
図5Aから図8Dに、スライダー型のタッチスクリーン用入力システム20を例示する。図4Aおよび図4Bに例示するように、本形態のタッチスクリーン用入力システム20は、タッチスクリーン15への入力と力覚の呈示とを行うための入力インタフェースであり、オブジェクト21(第1オブジェクト)とオブジェクト22(第2オブジェクト)と枠部23とを有する。
図5B、図6Aから図7Bに例示するように、本形態のオブジェクト21は、板面213(第1面)を含み、板面213がタッチスクリーン15の表示入力面151とは異なる面152に接触または近接して配置されるように構成されている。この例の面152は、表示入力面151の反対側の面である。オブジェクト21は、例えば、強磁性体を含む磁性シートである。しかし、必ずしもオブジェクト21がシート状である必要はなく、立方体や直方体等のその他の形状であってもよい。図6Aに例示するように、オブジェクト21の板面213には、特定の線(第1線)L1に従って、領域211(第1領域)と領域212(第2領域)とが繰り返し配置された繰り返し領域が予め設けられている。本形態では、領域211がN極に予め着磁されており、領域212がS極に予め着磁されている例を示す。なお、領域211と領域212とは互いに異なる領域である。例えば、板面213には、帯状の領域211と帯状の領域212とが線L1に沿って交互に周期的に配置されている。例えば、板面213には、領域211と領域212とが線L1に沿って交互に繰り返されたテクスチャが設けられているといってもよい。図6Aでは、線L1は直線であるが、線L1が曲線であってもよい。
図5Aから図7Bに例示するように、この例のオブジェクト22は、タッチスクリーン15側に配置される板面223と、その反対側の板面224とを持つ板状の部材であり、強磁性体部221と透明素材部222とを含む。オブジェクト22は、例えば、前述のスライダーとして機能する。本形態では、オブジェクト22が四角板状である例を示すが、オブジェクト22が円盤状等その他の形状であってもよい。
図5A、図5B、図8Aから図8Dに例示するように、この例の枠部23は矩形枠状の部材であり、その内側にオブジェクト22を配置し、配置されたオブジェクト22を所定のD2方向に(D2方向の軸に沿って)スライド移動可能な形状に構成されている。すなわち、枠部23の内側の幅はオブジェクト22の外形よりも若干大きく、枠部23の内側の長さはオブジェクト22よりも十分大きく、この長さ方向D2にオブジェクト22をスライドさせることができる。第1実施形態の枠部13と同様、枠部23は、透明素材または透過性を持つ素材を含むことが望ましい。
図5A、図8Aから図8Dに例示するように、本形態のタッチスクリーン15の表示入力面151上のある基準線LR上には、タッチスクリーン15に入力されるパラメータの最小値から最大値までが昇順または降順に割り当てられている。例えば、本形態のタッチスクリーン用入力システム20が、所定の最小値と最大値の間の範囲内で自由に設定可能なパラメータ値を所望の値に設定する際の操作に用いられる入力インタフェースである場合、そのパラメータの最小値から最大値に対応する位置が基準線LRに沿って割り当てられていればよい。例えば、基準線LRがタッチスクリーン15の横方向に延びる線である場合、例えば、スライド入力操作を受け付ける領域の左端を最小値に割り当て、スライド入力操作を受け付ける領域の右端を最大値に割り当てればよい。例えば、基準線LRがタッチスクリーン15の縦方向に延びる線である場合、例えば、スライド入力操作を受け付ける領域の下端を最小値に割り当て、スライド入力操作を受け付ける領域の上端を最大値に割り当てればよい。表示入力面151には、このような割り当てを表す表示内容250-1,250-2が表示可能である。本形態では、基準線LRがタッチスクリーン15の横方向に延びる直線(線分)である例を示すが、これは本発明を限定するものではない。すなわち、基準線LRがタッチスクリーン15の縦方向に延びる直線(線分)であってもよいし、基準線LRがその他の方向に延びる直線(線分)であってもよいし、基準線LRが曲線であってもよい。
図5Aおよび図5B等に例示するように、タッチスクリーン15の面152側にオブジェクト21が配置される。この際、オブジェクト21の板面213が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151には枠部23が配置され、枠部23の内側にはオブジェクト22が配置される。この枠部23によって、オブジェクト22が表示入力面151側で基準線LRに沿ってD2方向にスライド可能なように位置決めされる。すなわち、オブジェクト21とオブジェクト22は、表示入力面151上の基準線LRがオブジェクト21の線L1に沿って配置され、かつ、オブジェクト22の強磁性体部221が基準線LR上または基準線LRの近傍となるように配置される。オブジェクト22は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト22の板面223が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト22と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト22の板面223が、表示入力面151に近接して配置されてもよい。
利用者Uは、指等の身体部位でオブジェクト22の板面224に触れ、オブジェクト22を基準線LRに沿ったD2方向にスライドさせることができる(図7Aから図8D)。オブジェクト22をD2方向にスライドさせた場合、オブジェクト22のオブジェクト21に対する相対位置に応じて、上述した状態Aと状態Bが繰り返される。そのため、このスライド操作により、利用者Uがオブジェクト22から反発力を受けない状態Aと、反発力を受ける状態Bと、が繰り返される。その結果、利用者Uは、スライド操作に伴う力覚(凹凸感)を知覚する。
第2実施形態で説明したS極とN極とが反転していてもよい。また、第2実施形態で異なる磁極(S極とN極)によって吸引力が発生する構成が、磁石の何れかの磁極と磁石ではない強磁性体(例えば、鉄)とによって吸引力が発生する構成に置換されてもよい。
強磁性体部221の面2213に導電体が配置されていれば、必ずしも面2213と面2214が電気的に導通していなくてもよいし、必ずしも面2214に導電体が配置されていなくてもよい。このような場合でも、参考文献1,2等に記載された技術を用いることで、入力位置1511への入力を行うことができる。
導電体がオブジェクト22の板面223と板面224に位置し、これらを電気的に導通させているのであれば、強磁性体部221の表面が導電体でなくてもよい。また、参考文献1,2等に記載された技術を用いる場合には、導電体がオブジェクト22の板面223に位置しているのであれば、必ずしも板面223と板面224が電気的に導通していなくてもよいし、必ずしも板面224に導電体が配置されていなくてもよい。
第3実施形態では、回転操作によってタッチスクリーンへの入力を行うダイヤル型のタッチスクリーン用入力システムを例示する。このダイヤル型のタッチスクリーン用入力システムは、回転操作によるパラメータの入力と、利用者への力覚の呈示を可能にする。このようなダイヤル型のタッチスクリーン用入力システムは、例えば、自由に設定可能とされているパラメータ値を利用者が所望の値に設定する際の操作に用いられる入力インタフェースである。利用者は、例えば、ダイヤルを回転させる操作(回転操作)によって、利用者(操作者)の周囲に配置された複数のスピーカから出力する音量を同時に制御することで利用者に対する音の到来方向を操作したり、天井に配置された照明の位置を制御することで利用者に対する光の到来方向を操作したり、機械を向ける方向を操作したりできる。
図9Aから図11Cに、ダイヤル型のタッチスクリーン用入力システム30を例示する。図9Aおよび図9Bに例示するように、本形態のタッチスクリーン用入力システム30は、タッチスクリーン15への入力と力覚の呈示とを行うための入力インタフェースであり、オブジェクト31(第1オブジェクト)とオブジェクト32(第2オブジェクト)と枠部33とを有する。
図9Bおよび図10Aに例示するように、本形態のオブジェクト31は、板面313(第1面)を含み、板面313がタッチスクリーン15の表示入力面151とは異なる面152に接触または近接して配置されるように構成されている。この例の面152は、表示入力面151の反対側の面である。オブジェクト31は、例えば、強磁性体を含む磁性シートである。しかし、必ずしもオブジェクト31がシート状である必要はなく、立方体や直方体等のその他の形状であってもよい。図10A例示するように、オブジェクト31の板面313には、板面313と垂直または略垂直な軸O1(第1軸)の軸周り方向R3に沿って回転対称または略回転対称に領域311(第1領域)と領域312(第2領域)とが繰り返し配置された繰り返し領域が予め設けられている。本形態では、領域311がN極に予め着磁されており、領域312がS極に予め着磁されている例を示す。なお、略垂直とは、垂直または垂直に近い状態を表す。垂直に近い状態とは、例えば、垂直との角度差が5°以下の状態を表す。また、略回転対称とは回転対称に近い状態を表す。回転対称に近い状態とは、例えば、回転対称な配置との角度差が5°以下の状態を表す。領域311と領域312とは互いに異なる領域である。例えば、板面313には、領域311と領域312とが、軸O1の軸周り方向R3に沿って交互に周期的に配置されている。例えば、板面313には、領域311と領域312とが、軸O1の軸周り方向R3に沿って交互に繰り返されたテクスチャが設けられているといってもよい。ここでは、領域311の辺縁部が円形である例を示すが、これは本発明を限定するものではなく、領域311の辺縁部が四角形や三角形等のその他の形状であってもよい。また、ここでは、板面313のうち、領域311を除くすべての領域が領域312である例を示すが、これは本発明を限定するものではない。板面313に、領域311と領域312とそれらと異なる領域とが設けられていてもよい。例えば、辺縁部が円形である領域311と辺縁部が円形である領域312とが軸O1の軸周り方向に沿って交互に繰り返し配置され、板面313のうち領域311,312以外の領域がさらに設けられていてもよい。
図9A,図9B,図10B,図10Cに例示するように、この例のオブジェクト32は、タッチスクリーン15側に配置される板面323(第2面)と、その反対側の板面324とを持つ板状の部材であり、透明素材部322と複数の強磁性体部321とを含む。強磁性体部321は透明素材部322に対して固定されている。本形態では、オブジェクト32のうち、強磁性体部321以外の部分が透明素材部322である例を示す。しかし、オブジェクト32がその他の部材を含んでいてもよい。なお、オブジェクト32は、例えば、前述のダイヤルとして機能する。
図9A、図9B、図11Aから図11Cに例示するように、この例の枠部33は円形枠状の部材であり、その内側にオブジェクト32を配置し、配置されたオブジェクト32を、軸O2を中心に回転可能な形状に構成されている。すなわち、枠部33の内側の直径はオブジェクト32の直径よりも若干大きい。第1実施形態の枠部13と同様、枠部33は、透明素材または透過性を持つ素材を含むことが望ましい。
図9A、図11Aから図11Cに例示するように、本形態のタッチスクリーン15の表示入力面151上の軸O3(第3軸)の軸周りの各方向には、タッチスクリーン15に入力されるパラメータの値が所定の規則に従って割り当てられている。ここで、軸O3は、表示入力面151と垂直または略垂直な軸である。例えば、本形態のタッチスクリーン用入力システム30が、音や光などの利用者への到来方向を利用者(操作者)が設定する際の操作に用いられる入力インタフェースである例であるならば、タッチスクリーン15の回転入力操作を受け付ける領域の上側を利用者Uの前方向(利用者Uの向きに対する右回りの角度が0度)に割り当て、タッチスクリーン15の回転入力操作を受け付ける領域の下側を利用者の後方向(利用者の向きに対する右回りの角度が180度)に割り当て、タッチスクリーン15の回転入力操作を受け付ける領域の右側を利用者の右方向(利用者の向きに対する右回りの角度が90度)に割り当て、タッチスクリーン15の回転入力操作を受け付ける領域の左側を利用者の左方向(利用者の向きに対する右回りの角度が270度)に割り当てればよい。例えば、本形態のタッチスクリーン用入力システム30が、機械を向ける方位を利用者が設定する操作に用いられる入力インタフェースである例であるならば、タッチスクリーン15の回転入力操作を受け付ける領域の上側を北方向に割り当て、タッチスクリーン15の回転入力操作を受け付ける領域の下側を南方向に割り当て、タッチスクリーン15の回転入力操作を受け付ける領域の右側を東方向に割り当て、タッチスクリーン15の回転入力操作を受け付ける領域の左側を西方向に割り当てればよい。タッチスクリーン15の表示入力面151には、その割り当てを表す表示内容350-1,350-2が表示可能である。
図9Aおよび図9B等に例示するように、タッチスクリーン15の面152側にオブジェクト31が配置される。この際、オブジェクト31の板面313が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151には枠部33が配置され、枠部33の内側にはオブジェクト32が配置される。ここで、タッチスクリーン15とオブジェクト31,32は、前述の軸O1(第1軸)と軸O2(第2軸)と軸O3(第3軸)とが一致または近接するように配置される。また、枠部33の中心軸もこれらの軸O1,O2,O3の少なくとも何れかと一致または近接するように配置される。この枠部33によって、オブジェクト32が、表示入力面151側で、軸O2を中心とした軸周り方向R3に回転可能なように位置決めされる。オブジェクト32は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト32の板面323が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト32と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト32の板面323が、表示入力面151に近接して配置されてもよい。
利用者Uは、指等の身体部位でオブジェクト32の板面324に触れ、オブジェクト32を、軸O2を中心に軸O2の軸周り方向R3に回転させることができる(図11Aから図11C)。オブジェクト32を軸周り方向R3に回転させた場合、オブジェクト32のオブジェクト31に対する姿勢に応じて、上述した回転姿勢Aと回転姿勢Bが繰り返される。そのため、この回転操作により、利用者Uがオブジェクト32から反発力を受けない回転姿勢Aと、反発力を受ける回転姿勢Bと、が繰り返される。その結果、利用者Uは、回転操作に伴う力覚(凹凸感)を知覚する。また、オブジェクト31の板面313に軸O1の軸周り方向R3に沿って回転対称または略回転対称に領域311と領域312とを繰り返し配置し、オブジェクト32に軸O2の軸周り方向R3に沿って回転対称または略回転対称に複数の強磁性体部321を配置し、軸O1,O2が一致または近接するようにオブジェクト31,32を配置したため、オブジェクト32のスムーズな回転操作が可能となっている。
第3実施形態で説明したS極とN極とが反転していてもよい。また、第3実施形態で異なる磁極(S極とN極)によって吸引力が発生する構成が、磁石の何れかの磁極と磁石ではない強磁性体(例えば、鉄)とによって吸引力が発生する構成に置換されてもよい。
強磁性体部321の面3213に導電体が配置されていれば、必ずしも面3213と面3214が電気的に導通していなくてもよいし、し、必ずしも面3214に導電体が配置されていなくてもよい。このような場合でも、参考文献1,2等に記載された技術を用いることで、入力位置1511への入力を行うことができる。
導電体がオブジェクト32の板面323と板面324に位置し、これらを電気的に導通させているのであれば、強磁性体部321の表面が導電体でなくてもよい。また、参考文献1,2等に記載された技術を用いてもよい。この場合には、導電体がオブジェクト32の板面323に位置しているのであれば、必ずしも板面323と板面324が電気的に導通していなくてもよいし、必ずしも板面324に導電体が配置されていなくてもよい。
第3実施形態では、オブジェクト31の板面313に軸O1の軸周り方向R3に沿って回転対称または略回転対称に領域311と領域312とを繰り返し配置し、オブジェクト32に軸O2の軸周り方向R3に沿って回転対称または略回転対称に複数の強磁性体部321を配置し、軸O1,O2が一致または近接するようにオブジェクト31,32を配置したため、オブジェクト32のスムーズな回転操作が可能となっている。しかし、これによって表示入力面151への入力に必要なオブジェクト32の導電体も軸O2の軸周り方向R3に沿って回転対称または略回転対称となると、オブジェクト32のオブジェクト31に対する回転方向(例えば、ロータリーエンコーダの回転方向)をタッチスクリーン15に入力することはできても、オブジェクト32のオブジェクト31に対する姿勢(回転角度)をタッチスクリーン15に入力することはできない。
第4実施形態では、タッチスクリーンへの入力を行うサムスティック型のタッチスクリーン用入力システムを例示する。このサムスティック型のタッチスクリーン用入力システムは、サムスティック操作によるパラメータの入力と、利用者への力覚の呈示を可能にする。
図13Aから図17Cに、サムスティック型のタッチスクリーン用入力システム40を例示する。図13Aおよび図13Bに例示するように、本形態のタッチスクリーン用入力システム40は、タッチスクリーン15への入力と力覚の呈示とを行うための入力インタフェースであり、オブジェクト41(第1オブジェクト)とオブジェクト42(第2オブジェクト)と枠部43とを有する。
図13Bおよび図15Aから図16Bに例示するように、本形態のオブジェクト41は、板面413(第1面)を含み、板面413がタッチスクリーン15の表示入力面151とは異なる面152に接触または近接して配置されるように構成されている。この例の面152は、表示入力面151の反対側の面である。オブジェクト41は、例えば、強磁性体を含む磁性シートである。しかし、必ずしもオブジェクト41がシート状である必要はなく、立方体や直方体等のその他の形状であってもよい。図14A等に例示するように、オブジェクト41の板面413には、板面413と垂直または略垂直な軸O1上に配置された1つの領域411(第1領域)とそれ以外の領域412(第2領域)とが予め設けられている。本形態では、領域411がN極に予め着磁されており、領域412がS極に予め着磁されている例を示す。ここでは、領域411の辺縁部が円形である例を示すが、これは本発明を限定するものではなく、領域411の辺縁部が四角形や三角形等のその他の形状であってもよい。また、ここでは、板面413のうち、領域411を除くすべての領域が領域412である例を示すが、これは本発明を限定するものではない。板面413に、領域411と領域412とそれらと異なる領域とが設けられていてもよい。
図13A,図13B,図14B,図14Cに例示するように、この例のオブジェクト42は、タッチスクリーン15側に配置される板面423と、その反対側の板面424とを持つ板状の部材であり、板面423と垂直または略垂直な軸O2上に配置された1個の強磁性体部421と透明素材部422とを含む。強磁性体部421は透明素材部422に対して固定されている。本形態では、オブジェクト42のうち、強磁性体部421以外の部分が透明素材部422である例を示す。しかし、オブジェクト42がその他の部材を含んでいてもよい。本形態では、強磁性体部421が、透明素材部422に囲まれている例を示す。すなわち、本形態では、透明素材部422が、強磁性体部421の周囲に配置されている例を示す。しかし、これは本発明を限定するものではない。
図13A、図13B、図15Aから図17Cに例示するように、この例の枠部43は、円形枠状の部材であり、その内側にオブジェクト42を配置し、配置されたオブジェクト42を枠部43の内側で表示入力面151に沿ったD41方向およびD42方向に移動可能(スライド操作が可能)な形状に構成されている。すなわち、枠部43の内側の直径はオブジェクト42の直径よりも十分に大きい。ここで、D41方向は、表示入力面151と平行な特定の方向である。D42方向は、D41方向と垂直かつ表示入力面151と平行な方向である。ここでは、D41方向が図13Aにおける左右方向であり、D42方向が図13Aにおける上下方向である例を示す。しかし、これは本発明を限定するものではない。第1実施形態の枠部13と同様、枠部43は、透明素材または透過性を持つ素材を含むことが望ましい。
図13A、図17Aから図17Cに例示するように、表示入力面151には、オブジェクト42の位置を表す表示内容450-1,450-2が表示可能である。例えば、本形態のタッチスクリーン15の表示入力面151上の軸O3を中心とした領域には、タッチスクリーン15に入力されるD41方向の軸のパラメータP41とD42方向の軸のパラメータP42が割り当てられている。軸O3は表示入力面151と垂直または略垂直な軸である。例えば、軸O3と交差する表示入力面151上の基準位置Oには、パラメータP41,P42の基準値(最小値または最大値)が割り当てられている。例えば、表示入力面151上の基準位置OからD41方向の外側に向かってパラメータP41の基準値から最大値および/または最小値までが昇順または降順に割り当てられている。例えば、表示入力面151上の基準位置OからD42方向の外側に向かってパラメータP42の基準値から最大値および/または最小値までが昇順または降順に割り当てられている。
図13A,図13B,図15Aから図16B等に例示するように、タッチスクリーン15の面152側にオブジェクト41が配置される。オブジェクト41およびタッチスクリーン15は、オブジェクト41の軸O1とタッチスクリーン15の軸O3とが一致または近接し、オブジェクト41の板面413が、タッチスクリーン15の面152に接触または近接するように配置される。タッチスクリーン15の表示入力面151には枠部43が配置され、枠部43の内側にはオブジェクト42が配置される。この枠部43によって、オブジェクト42が表示入力面151側でD41方向およびD42方向にスライド可能なように位置決めされる。枠部43は、枠部43の内側にオブジェクト41の軸O1が位置するように配置される。例えば、枠部43は、枠部43の内側の中央または中央の近傍に軸O1が位置するように配置される。オブジェクト42は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、例えば、オブジェクト42の板面423が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト42と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト42の板面423が、表示入力面151に近接して配置されてもよい。
利用者Uは、指等の身体部位でオブジェクト42の板面424に触れ、オブジェクト42を、表示入力面151上で、D41方向およびD42方向にスライドさせることができる(図15B,図16A,図16B,図17A,図17B)。オブジェクト42をD41方向およびD42方向にスライドさせた場合、オブジェクト42のオブジェクト41の領域411に対する相対位置に応じて、上述した状態Aと状態Bが生じる。上述のように、状態Aでは、状態Aを維持しようとする力がオブジェクト42に加わり、状態Bでは、状態Aに近づけようとする力がオブジェクト42に加わる。これにより、利用者Uは、オブジェクト42のスライド操作の際に、オブジェクト42を領域411側(例えば、中央または中央付近)に復帰させようとする力覚を知覚する。
第4実施形態で説明したS極とN極とが反転していてもよい。
強磁性体部421の面4213に導電体が配置されていれば、必ずしも面4213と面4214が電気的に導通していなくてもよいし、必ずしも面4214に導電体が配置されていなくてもよい。このような場合でも、参考文献1,2等に記載された技術を用いることで、入力位置1511への入力を行うことができる。
導電体がオブジェクト42の板面423と板面424に位置し、これらを電気的に導通させているのであれば、強磁性体部421の表面が導電体でなくてもよい。また、参考文献1,2等に記載された技術を用いる場合には、導電体がオブジェクト42の板面423に位置しているのであれば、必ずしも板面423と板面424が電気的に導通していなくてもよいし、必ずしも板面424に導電体が配置されていなくてもよい。
第5実施形態では、タッチスクリーンへの入力を行うジョイスティック型のタッチスクリーン用入力システムを例示する。このジョイスティック型のタッチスクリーン用入力システムは、ジョイスティック操作によるパラメータの入力と、利用者への力覚の呈示を可能にする。
図18Aから図21Cに、ジョイスティック型のタッチスクリーン用入力システム50を例示する。図18Aおよび図18Bに例示するように、本形態のタッチスクリーン用入力システム50は、タッチスクリーン15への入力と力覚の呈示とを行うための入力インタフェースであり、オブジェクト41(第1オブジェクト)とオブジェクト52(第2オブジェクト)と枠部53とを有する。
オブジェクト41は、第4実施形態で説明したものと同じである。
図18Aから図20Bに例示するように、この例のオブジェクト52は、矩形板状の中央部5201と、中央部5201の4辺から外方に延びる4個の矩形板状の傾斜部5202と、中央部5201の一方の板面524側から延びる棒状の導電体525と、中央部5201および傾斜部5202の他方の板面523側に設けられた導電体526とを有する。ここで、中央部5201および傾斜部5202の板面のうち、タッチスクリーン15側に配置される板面を板面523と呼び、その反対側の板面を板面524と呼ぶ。傾斜部5202は、それぞれ、中央部5201の何れかの辺につながり、板面524側に傾斜している。言い換えると、傾斜部5202は、中央部5201に対して板面524側に反っている。例えば、中央部5201と傾斜部5202の板面523はつながっているが、中央部5201の板面523と傾斜部5202の板面523とは同一平面上に配置されておらず、これらは一定の角度θ5を持っている。なお、0°<θ5<180°であり、例えば、1°<θ5≦90°である。また、中央部5201は、中央部5201の板面523と垂直または略垂直な軸O2上に配置された1個の強磁性体部521を含み、中央部5201の強磁性体部521以外の部分および傾斜部5202は、透明素材部522である。強磁性体部521は、透明素材部522に対して固定されている。
図18A、図18B、図20Aから図21Cに例示するように、この例の枠部53は、円形枠状の部材であり、その内側にオブジェクト52を配置可能な形状に構成されている。枠部53は、オブジェクト52を一定の範囲に位置決めするが、利用者Uの操作に基づくオブジェクト52の動きを妨げない形状とされている。第1実施形態の枠部13と同様、枠部53は、透明素材または透過性を持つ素材を含むことが望ましい。
図18A、図21Aから図21Cに例示するように、表示入力面151には、オブジェクト52の傾き姿勢を表す表示内容550-1,550-2が表示可能である。例えば、本形態のタッチスクリーン15の表示入力面151上の軸O3を中心とした領域には、タッチスクリーン15に入力されるD51方向の傾きのパラメータP51とD52方向の傾きのパラメータP52が割り当てられている。軸O3は表示入力面151と垂直または略垂直な軸である。ここで、D51方向は、表示入力面151と平行な特定の方向である。D52方向は、D51方向と垂直かつ表示入力面151と平行な方向である。ここでは、D51方向が図18Aにおける左右方向であり、D52方向が図18Aにおける上下方向である例を示す。例えば、軸O3と交差する表示入力面151上の基準位置OのD51方向の一方(例えば、図18Aの左側)側の割り当て領域A1には、この方向への傾き姿勢を表すパラメータP51の値が割り当てられ、表示入力面151上の基準位置OのD51方向の他方(例えば、図18Aの右側)側の割り当て領域A2には、この方向への傾き姿勢を表すパラメータP51の値が割り当てられている。例えば、表示入力面151上の基準位置OのD52方向の一方(例えば、図18Aの上側)側の割り当て領域A3には、この方向への傾き姿勢を表すパラメータP52の値が割り当てられ、表示入力面151上の基準位置OのD52方向の他方(例えば、図18Aの下側)側の割り当て領域A4には、この方向への傾き姿勢を表すパラメータP52の値が割り当てられている。
図18A,図18B,図20Aおよび図20Bに例示するように、タッチスクリーン15の面152側にオブジェクト41が配置される。オブジェクト41およびタッチスクリーン15は、オブジェクト41の軸O1とタッチスクリーン15の軸O3とが一致または近接し、オブジェクト41の板面513が、タッチスクリーン15の面152に接触または近接するように配置される。タッチスクリーン15の表示入力面151には枠部53が配置される。枠部53は、枠部53の内側にオブジェクト41の軸O1が位置するように配置される。例えば、枠部53は、枠部53の内側の中央または中央の近傍に軸O1が位置するように配置される。表示入力面151上の枠部53の内側には、オブジェクト52が配置される。この枠部53によって、オブジェクト52がD51方向およびD52方向に傾斜可能なように表示入力面151側で位置決めされる。ここで、枠部53の内側に配置されたオブジェクト52は、板面523側が表示入力面151側に位置するように配置される。さらにオブジェクト52は、強磁性体部521の面5213が、オブジェクト41の板面413の領域411を向くように配置される。すなわち、オブジェクト52が傾斜していないときに、軸O2が軸O1,O3と一致または近接するように、オブジェクト41,52、枠部53、およびタッチスクリーン15が配置される(図20A)。また、オブジェクト52は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト52と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト52が、タッチスクリーン15の表示入力面151に近接して配置されていてもよい。
利用者Uは、指等の身体部位でオブジェクト52の導電体525に触れ、オブジェクト52を、D51方向および/またはD52方向に傾斜させる。すなわち、オブジェクト52の軸O2を軸O1,O3に対してD51方向および/またはD52方向に傾斜させる(図20Aから図21C)。オブジェクト52を傾斜させていない直立状態Aでは、直立状態Aを維持しようとする力がオブジェクト52に加わる。一方、オブジェクト52を傾斜させた傾斜状態Bでは、直立状態Aに復帰させようとする力がオブジェクト52に加わる。これにより、利用者Uは、オブジェクト52の傾斜操作の際に、オブジェクト52を直立状態Aに復帰させようとする力覚を知覚する。
第5実施形態で説明したS極とN極とが反転していてもよい。
参考文献1,2等に記載された技術を用いる場合には、必ずしも導電体525と導電体526が電気的に導通していなくてもよいし、必ずしも導電体525が設けられていなくてもよい。
第6実施形態では、タッチスクリーンへの入力とその利用者への力覚、振動、動き、音等の物理現象の呈示とを行うためのフラップ型のタッチスクリーン用入力システム60を例示する。
図22Aから図27Dに、フラップ型のタッチスクリーン用入力システム60を例示する。図22Aおよび図22Bに例示するように、本形態のタッチスクリーン用入力システム60は、タッチスクリーン15への入力と力覚、振動、動き、音等の物理現象の呈示とを行うための入力インタフェースであり、オブジェクト61(第1オブジェクト)とオブジェクト62(第2オブジェクト)とを有する。
図22Bから25Bに例示するように、本形態のオブジェクト61は、板面613(第1面)を含み、板面613がタッチスクリーン15の表示入力面151とは異なる面152に接触または近接して配置されるように構成されている。この例の面152は、表示入力面151の反対側の面である。オブジェクト61は、例えば、強磁性体を含む磁性シートである。しかし、必ずしもオブジェクト61がシート状である必要はなく、立方体や直方体等のその他の形状であってもよい。図23Aおよび図23Bに例示するように、オブジェクト61の板面613には、領域611(第1領域)と領域612(第2領域)とが繰り返し配置された繰り返し領域が予め設けられている。本形態では、領域611がN極に予め着磁されており、領域612がS極に予め着磁されている例を示す。なお、領域611と領域612とは互いに異なる領域である。例えば、図23Aに例示するように、板面213に、帯状の領域611と帯状の領域612とが線L1に沿って繰り返し配置されていてもよいし、図23Bに例示するように、矩形状の領域611と矩形状の領域612とが繰り返し格子状に繰り返し配置されていてもよい。
図22Aから図25Bに例示するように、この例のオブジェクト62は、板状のベース部分620-1と、ベース部分620-1に対して回動する可動部分620-2と、可撓性があるテープ状の導電体625とを有する。この例のベース部分620-1および可動部分620-2は四角板状である。ただし、これは本発明を限定するものではなく、ベース部分620-1および可動部分620-2が四角板状以外の形状であってもよい。ここで、ベース部分620-1の一方の板面623-1と可動部分620-2の一方の板面623-2とは互いに同じ側に配置されている。また、ベース部分620-1の他方の板面624-1と可動部分620-2の他方の板面624-2とは、ともに板面623-1および板面623-2の反対側に配置されている。ベース部分620-1の板面624-1と可動部分620-2の他方の板面624-2とは、導電体625を介して接続されている。導電体625は、導電性テープ等の可撓性を持つ素材で構成されており、可動部分620-2は、板面624-1と板面624-2との間の軸626を中心に、R6回転方向に回動可能に構成されている。板面624-1と板面624-2は、導電体625のみによって接続されていてもよいし、板面624-1と板面624-2とがさらに蝶番によって回動可能に接続されていてもよい。板面623-1と板面623-2は、タッチスクリーン15側に配置される板面であり、板面624-1と板面624-2は、タッチスクリーン15の反対側に配置される板面である。可動部分620-2は、軸626を中心に、ベース部分620-1に対して板面624-2側(タッチスクリーン15の反対側)に回動可能である。
図22Aおよび図22B等に例示するように、タッチスクリーン15の面152側にオブジェクト61が配置される。この際、オブジェクト61の板面613が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151にはオブジェクト62が配置される。オブジェクト62は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト62の板面623-1,623-2が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト62と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト62の板面623-1,623-2が、表示入力面151に近接して配置されてもよい。すなわち、ベース部分620-1の表示入力面151側に配置される面が板面623-1(第3部分面)であり、可動部分620-2の表示入力面151側に配置される面が板面623-2(第4部分面)である。
利用者Uは、指等の身体部位でオブジェクト62のベース部分620-1の板面624-1側(導電体625)に触れ、オブジェクト62をD61方向およびD62方向にスライドさせることができる(図24Bから図27D)。オブジェクト62をスライドさせた場合、オブジェクト62のオブジェクト61に対する相対位置に応じて、上述した基準状態Aと回動状態Bが繰り返される。これにより、可動部分620-2がオブジェクト61から吸引力を受ける基準状態Aと、反発力を受ける回動状態Bと、が繰り返される。可動部分620-2に接続されたベース部分620-1に触れている利用者Uは、このスライド操作に伴う力覚や振動を知覚する。また、利用者Uは、可動部分620-2が回動していない基準状態Aと、回動している回動状態Bとを繰り返す動きを視覚的に知覚する。また、回動状態Bから基準状態Aに移ると、可動部分620-2の板面623-2が表示入力面151にぶつかり、音が発生する。利用者Uは、この音も知覚する。このように、利用者Uは、基準状態Aと回動状態Bが繰り返されることによる力覚、振動、動き、音等の物理現象を知覚できる。
第6実施形態で説明したS極とN極とが反転していてもよい。また、第6実施形態で異なる磁極(S極とN極)によって吸引力が発生する構成が、磁石の何れかの磁極と磁石ではない強磁性体(例えば、鉄)とによって吸引力が発生する構成に置換されてもよい。
強磁性体部621-2の面6213-2に導電体が配置されていれば、必ずしも面6213-2と面6214-2が電気的に導通していなくてもよいし、必ずしも面6214-2に導電体が配置されていなくてもよいし、導電体625が絶縁体に置換されてもよい。このような場合でも、参考文献1,2等に記載された技術を用いることで、入力位置1511への入力を行うことができる。
導電体がオブジェクト62の板面623-2と板面624-2に位置し、これらを電気的に導通させているのであれば、強磁性体部621-2の表面が導電体でなくてもよい。また、参考文献1,2等に記載された技術を用いる場合には、導電体がオブジェクト62の板面623-2に位置しているのであれば、必ずしも板面623-2と板面624-2が電気的に導通していなくてもよいし、必ずしも板面624-2に導電体が配置されていなくてもよい。

第2実施形態で説明した通りである。
図28Aおよび図28Bに例示するように、タッチスクリーン15の面152側にオブジェクト21が配置される。この際、オブジェクト21の板面213が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151には枠部23が配置され、枠部23の内側にはオブジェクト62が配置される。この枠部23によって、オブジェクト62が表示入力面151側で基準線LRに沿ってD2方向にスライド可能なように位置決めされる。すなわち、オブジェクト21とオブジェクト62は、表示入力面151上の基準線LRがオブジェクト21の線L1に沿って配置され、かつ、基準状態Aでは、板面623-1(第3部分面)および板面623-2(第4部分面)が基準線LR上または基準線LRの近傍に位置し、回動状態Bでは、板面623-1が基準線LR上または基準線LRの近傍に位置するように配置される。図25Aおよび図25Bに例示したように、回動状態Bでは、板面623-1は、基準状態Aよりも表示入力面151から離れる。オブジェクト62と表示入力面151との間に薄いシート等の部材が介在してもよい。
利用者Uは、指等の身体部位でオブジェクト62のベース部分620-1の板面624-1側(導電体625)に触れ、オブジェクト62をD61方向にスライドさせることができる。オブジェクト62をスライドさせた場合、オブジェクト62のオブジェクト21に対する相対位置に応じて、上述した基準状態Aと回動状態Bが繰り返される。これにより、可動部分620-2がオブジェクト21から吸引力を受ける基準状態Aと、反発力を受ける回動状態Bと、が繰り返される。その結果、利用者Uは、力覚、振動、動き、音等の物理現象を知覚できる。
第6実施形態またはその変形例1から3のタッチスクリーン用入力システム60を、第3実施形態で説明したようなダイヤル型のタッチスクリーン用入力システム60”として実装してもよい。
第3実施形態で説明した通りである。
第6実施形態およびその変形例1から3で説明した通りである。
第3実施形態で説明した通りである。
<中央部63>
中央部63は、円盤状の板である。中央部63は、透明素材または透過性を持つ素材を有することが望ましい。中央部63の外形は枠部33の内径よりも十分に小さく、枠部33の内側の中央に配置されるように構成されている。さらに、枠部33の内側に中央部63を配置し、枠部33と中央部63との間にオブジェクト62を配置した場合に、中央部63の周りでオブジェクト62を移動させることができるように構成されている。
第3実施形態で説明した通りである。
図29Aおよび図29Bに例示するように、タッチスクリーン15の面152側にオブジェクト31が配置される。この際、オブジェクト31の板面313が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151には枠部33が配置される。枠部33の内側の中央には中央部63が配置される。さらに、枠部33の内側と中央部63との間にオブジェクト62が配置される。ここで、オブジェクト31とタッチスクリーン15とは、前述のオブジェクト31の軸O1(第1軸)とタッチスクリーン15の軸O3(第3軸)とが一致または近接するように配置される。また、枠部33および中央部63の中心軸もこれらの軸O1,O3の少なくとも何れかと一致または近接するように配置される。このように配置された枠部33と中央部63とによって、オブジェクト62が、表示入力面151側で、軸O1,O3を中心とした軸周り方向R3に、中央部63の周囲を移動可能なように位置決めされる。すなわち、オブジェクト31とオブジェクト62は、軸O1と軸O3とが一致または近接し、かつ、基準状態Aでは、板面623-1(第3部分面)および板面623-2(第4部分面)が表示入力面151上の軸O3(第3軸)の軸周りに位置し、回動状態Bでは、板面623-1が表示入力面151上の軸O3の軸周りに位置するように配置される。図25Aおよび図25Bに例示したように、回動状態Bでは、板面623-1は、基準状態Aよりも表示入力面151から離れる。オブジェクト62と表示入力面151との間に薄いシート等の部材が介在してもよい。
利用者Uは、指等の身体部位でオブジェクト62のベース部分620-1の板面624-1側(導電体625)に触れ、オブジェクト62を中央部63の周囲で移動させることができる。この移動により、オブジェクト62のオブジェクト31に対する相対位置に応じて、上述した基準状態Aと回動状態Bが繰り返される。これにより、可動部分620-2がオブジェクト31から吸引力を受ける基準状態Aと、反発力を受ける回動状態Bと、が繰り返される。その結果、利用者Uは、力覚、振動、動き、音等の物理現象を知覚できる。
第6実施形態の変形例6では、円形枠状の枠部33および円盤状の中央部63を用いたが、その他の形状であってもよい。例えば、枠部33に代えて矩形枠状の枠部が用いられてもよいし、中央部63に変えて矩形板状の中央部が用いられてもよい。また、中央部63を設けずに、枠部33の内側にオブジェクト62を配置し、ベース部分620-1を中心に配置し、可動部分620-2をその周囲に配置した状態で、利用者Uがオブジェクト62を軸O3の軸周りに回転させる操作を行ってもよい。このようにしても、タッチスクリーン15への入力と、利用者Uへの力覚、振動、動き、音等の物理現象の呈示とを行うことができる。この際に、前述のように、利用者Uによる操作に応じて、タッチスクリーン15の表示入力面151に表示される内容が変化してもよい。その他、第6実施形態およびその変形例において、オブジェクト62のベース部分620-1および可動部分620-2が矩形板状でなくてもよい。例えば、ベース部分620-1および可動部分620-2が半円盤状の板であり、ベース部分620-1と可動部分620-2とが導電体625を介して接続されることで、オブジェクト62全体の形状が円盤状となるように構成されていてもよい。
第7実施形態は、タッチスクリーンへの入力を行うとともに、第1から第6実施形態およびその変形例と同様に磁力に基づく力覚を呈示でき、さらに交流電流で磁石を振動させることによっても力覚を呈示できる振動型のタッチスクリーン用入力システムを例示する。
図30Aから図32に、本形態のタッチスクリーン用入力システム70を例示する。この例のタッチスクリーン用入力システム70は、タッチスクリーン15への入力と力覚等の物理現象の呈示とを行うための入力インタフェースであり、オブジェクト61(第1オブジェクト)とオブジェクト72(第2オブジェクト)とを有する。
第6実施形態で説明した通りである。
図30Aから図32に例示するように、本形態のオブジェクト72は、磁石721、筐体722、コイル723、および弾性体724を有する。
制御装置73は、コイル723に交流電流を供給(印加)する装置である。制御装置73は、例えば、コイル723に印加する交流電流の有無、および/または交流電流の大きさを変更可能である。例えば、制御装置73は、所定の基準に基づいてコイル723に印加する交流電流の有無、および/または交流電流の大きさを変更してもよい。例えば、制御装置73は、タッチスクリーン15への入力内容、時間、時刻等の少なくともいずれかに基づいて、コイル723に印加する交流電流の有無、および/または交流電流の大きさを変更してもよい。なお、制御装置73は、電流を制御する装置であってもよいし、電圧を制御する装置であってもよい。制御装置73がコイル723供給する交流電流の周波数は、利用者Uに知覚させる力覚に応じて異なる。交流電流の周波数は、例えば、15Hzから40kHz程度である。しかし、これは本発明を限定するものではない。
図30Aから図31Bに例示するように、タッチスクリーン15の面152側にオブジェクト61が配置される。この際、オブジェクト61の板面613が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151にはオブジェクト72が配置される。ここで、オブジェクト72は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト72の筐体722の板面7223が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト72と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト72の板面7223が、表示入力面151に近接して配置されてもよい。
利用者Uは、指等の身体部位でオブジェクト72の磁石721の面7214に触れ、オブジェクト72をD71方向およびD72方向にスライドさせることができる(図30Aから図32)。この際、好ましくは、利用者Uは、磁石721の面7214のみならず、筐体722の開口端7224側の端部7222に触れた状態で、オブジェクト72をスライドさせることが好ましい(図31B)。身体部位が磁石721のみに触れていると、オブジェクト72をスライドさせるために磁石721に力を加えた際に、上述した磁石721の振動を抑制または静止してしまうおそれがあるからである。つまり、利用者Uが磁石721と筐体722とに触れた状態でオブジェクト72をスライドさせることで、磁石721を十分に振動させることができる。
第7実施形態で説明したS極とN極とが反転していてもよい。
磁石721および弾性体724である可動部品の表示入力面151側に配置される端(例えば、弾性体724の一端7241)が導電体であるか、筐体722の板面7223が導電体であれば、必ずしも可動部品の表示入力面151とは反対側の端(例えば、磁石721の面7214)とこれらの導電体とが電気的に導通していなくてもよいし、可動部品の表示入力面151とは反対側の端に導電体が配置されていなくてもよい。このような場合でも、参考文献1,2等に記載された技術を用いることで、入力位置1511への入力を行うことができる。
第7実施形態およびその変形例1,2において、オブジェクト61が、タッチスクリーン15の表示入力面151とは異なる面に接触または近接して配置される面(第1面)にS極とN極が着磁されたその他のオブジェクト(例えば、オブジェクト11からオブジェクト41の何れか)に置き換えられてもよい。
オブジェクト72がさらに透明素材部を含み、オブジェクト72がタッチスクリーンの表示入力面151に接触または近接して配置されたときに、タッチスクリーン15の利用者Uが、表示入力面151の表示内容を、当該透明素材を介して視認可能となるようにされていてもよい。
第1実施形態から第6実施形態またはそれらの変形例の少なくとも何れかのタッチスクリーン用入力システムの強磁性体部を、第7実施形態のオブジェクト72に置き換えたタッチスクリーン用入力システムを用いてもよい。例えば、強磁性体部121-1,121-2,221,321,421,521,621-2を、第7実施形態のオブジェクト72に置き換えたタッチスクリーン用入力システム(例えば、ロッカースイッチ型、ボタン型、スライダー型、ダイヤル型、サムスティック型、ジョイスティック型、フラップ型のタッチスクリーン用入力システム)を用いてもよい。これにより、第1実施形態から第6実施形態またはそれらの変形例で得られる効果に加え、さらに第7実施形態で説明した効果が得られる。すなわち、この変形例では、タッチスクリーン15への入力を行った利用者Uがオブジェクト72(第2オブジェクト)の位置または姿勢をオブジェクト(第1オブジェクト)に対して変化させない場合においても、この利用者Uに磁力に基づく力覚、振動、動き、音等の物理現象を呈示することができる。
第8実施形態では、タッチスクリーンへの入力と、電磁石の磁力とオブジェクトとの間の磁力に基づく力覚等の物理現象の呈示とを行うための電磁石型のタッチスクリーン用入力システムを例示する。
第1オブジェクトの第1面のうちの、表示入力面の所定の入力位置に対応する第1領域と、ある方向に電流を印加した状態の電磁石と、の間では吸引力または反発力である第1方向の力が発生するようにされている。また、第1オブジェクトの第1面のうちの第1領域に近接する第2領域と、ある方向に電流を印加した状態の電磁石と、の間では、第1方向の力が発生しないようにされている。以下、具体例を示す。
図34Aから図35Bに、本形態のタッチスクリーン用入力システム80を例示する。この例のタッチスクリーン用入力システム80は、タッチスクリーン15への入力と力覚等の物理現象の呈示とを行うための入力インタフェースであり、オブジェクト61(第1オブジェクト)とオブジェクト82(第2オブジェクト)とを有する。
第6実施形態で説明した通りである。
図34Aから図35Bに例示するように、本形態のオブジェクト82は、強磁性体部821、筐体822、およびコイル823を有する。これらは電磁石として機能する。
制御装置83は、コイル823に直流電流を供給(印加)する装置である。制御装置83は、例えば、コイル823に印加する電流の有無、および/または電流の大きさ、および/または電流の向きを変更可能である。例えば、制御装置83は、所定の基準に基づいてコイル823に印加する電流の有無、および/または電流の大きさ、および/または電流の向きを変更してもよい。例えば、制御装置83は、タッチスクリーン15への入力内容、時間、時刻等の少なくともいずれかに基づいて、コイル823に印加する電流の有無、および/または電流の大きさ、および/または電流の向きを変更してもよい。なお、制御装置83は、電流を制御する装置であってもよいし、電圧を制御する装置であってもよい。
図34Aから図35Bに例示するように、タッチスクリーン15の面152側にオブジェクト61が配置される。この際、オブジェクト61の板面613が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151にはオブジェクト82が配置される。ここで、オブジェクト82は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト82の筐体822の端部8223および強磁性体部821の面8213が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト82と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト82の端部8223および面8213が、表示入力面151に近接して配置されてもよい。
利用者Uは、指等の身体部位でオブジェクト82の強磁性体部821の面8214に触れ、オブジェクト82をD81方向およびD82方向にスライドさせることができる(図34Aから図35B)。
オブジェクト82の表示入力面151側に配置される端の表面(例えば、強磁性体部821の面8213)が導電体であれば、必ずしも強磁性体部821の面8214と面8213とが電気的に導通していなくてもよいし、面8214に導電体が配置されていなくてもよい。このような場合でも、参考文献1,2等に記載された技術を用いることで、入力位置1511への入力を行うことができる。
第8実施形態において、オブジェクト61が、タッチスクリーン15の表示入力面151とは異なる面に接触または近接して配置される面(第1面)にS極とN極が着磁されたその他のオブジェクト(例えば、オブジェクト11からオブジェクト41の何れか)に置き換えられてもよい。例えば、図36Aおよび図36Bに例示するように、オブジェクト61がオブジェクト41に置き換えられたタッチスクリーン用入力システム80’を用いてもよい。
オブジェクト82がさらに透明素材部を含み、オブジェクト82がタッチスクリーンの表示入力面151に接触または近接して配置されたときに、タッチスクリーン15の利用者Uが、表示入力面151の表示内容を、当該透明素材を介して視認可能となるようにされていてもよい。
第1実施形態から第6実施形態またはそれらの変形例の少なくとも何れかのタッチスクリーン用入力システムの強磁性体部を、第8実施形態のオブジェクト82に置き換えたタッチスクリーン用入力システムが用いられてもよい。例えば、強磁性体部121-1,121-2,221,321,421,521,621-2を、第8実施形態のオブジェクト82に置換したタッチスクリーン用入力システム(例えば、ロッカースイッチ型、ボタン型、スライダー型、ダイヤル型、サムスティック型、ジョイスティック型、フラップ型のタッチスクリーン用入力システム)が用いられてもよい。これにより、第1実施形態から第6実施形態またはそれらの変形例で得られる効果に加え、さらに第8実施形態で説明した効果が得られる。すなわち、この変形例では、タッチスクリーン15への入力を行った利用者Uに呈示する、磁力に基づく物理現象を、動的に変化させることができる。
第9実施形態では、タッチスクリーン上を自律的に移動し、タッチスクリーンへの入力を行う自律型のタッチスクリーン用入力システムを例示する。すなわち、本形態では、利用者Uがオブジェクトに触れることなく、タッチスクリーンへの入力を行うことができる。
図34A、図34B、図37Aから図37Cに、本形態のタッチスクリーン用入力システム90を例示する。この例のタッチスクリーン用入力システム90は、自律的に移動してタッチスクリーン15への入力を行うための入力インタフェースであり、オブジェクト41(第1オブジェクト)とオブジェクト82(第2オブジェクト)とを有する。
第4実施形態で説明した通りである。
第8実施形態で説明した通りである。
図34A、図34B、図37Aから図37Cに例示するように、タッチスクリーン15の面152側にオブジェクト41が配置される。この際、オブジェクト41の板面413が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151にはオブジェクト82が配置される。ここで、オブジェクト82は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト82の筐体822の端部8223および強磁性体部821の面8213が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト82と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト82の端部8223および面8213が、表示入力面151に近接して配置されてもよい。
オブジェクト82の表示入力面151側に配置される端の表面(例えば、強磁性体部821の面8213)が導電体であれば、必ずしも強磁性体部821の面8214と面8213とが電気的に導通していなくてもよいし、面8214に導電体が配置されていなくてもよい。
オブジェクト82がさらに透明素材部(透明素材または透過性を持つ素材で構成された物)を含み、オブジェクト82がタッチスクリーンの表示入力面151に接触または近接して配置されたときに、タッチスクリーン15の利用者Uが、表示入力面151の表示内容を、当該透明素材部を介して視認可能となるようにされていてもよい。
第10実施形態では、タッチスクリーン上を自律的かつ連続的に移動し、タッチスクリーンへの入力を行うリニアモータ型のタッチスクリーン用入力システムを例示する。
図38Aから図41Bに、本形態のタッチスクリーン用入力システム100を例示する。この例のタッチスクリーン用入力システム100は、自律的かつ連続的に移動してタッチスクリーン15への入力を行うための入力インタフェースであり、オブジェクト61(第1オブジェクト)とオブジェクト102(第2オブジェクト)とを有する。
第6実施形態で説明した通りである。すなわち、オブジェクト61(第1オブジェクト)の板面613(第1面)の磁気パタンは、領域611と領域612とが繰り返し配置された周期的なパタンである。
本形態のオブジェクト102は、例えば、2個のオブジェクト82(複数個の電磁石)を含んでいる。すなわち、本形態のオブジェクト102は、例えば、第8実施形態で説明したオブジェクト82を2個連結(固定)したものである。これらの2個のオブジェクト82を、オブジェクト82-1,82-2と表記する。また、オブジェクト82-1が有する磁性体部821、筐体822、およびコイル823を、それぞれ磁性体部821-1、筐体822-1、およびコイル823-1と表記する。同様に、オブジェクト82-2が有する磁性体部821、筐体822、およびコイル823を、それぞれ磁性体部821-2、筐体822-2、およびコイル823-2と表記する。オブジェクト82-1,82-2を構成するその他の部位の表記も同様である。これらのオブジェクト82-1,82-2(複数個の電磁石)は、各オブジェクト82-1,82-2(電磁石)の一方の極が表示入力面151と接触または近接するように配置されている。例えば、オブジェクト82-1,82-2は、それぞれの強磁性体挿入穴8220-1,8220-2が平行または略平行に配置され、強磁性体部821-1,821-2も平行または略平行に配置され、強磁性体部821-1,821-2の面8213-1,8213-2が同一平面または略同一平面上に配置されるように連結されている。これらの面8213-1,8213-2は、表示入力面151と接触または近接するように配置されている。また、各オブジェクト82-1,82-2(電磁石)の極は、N極、S極、どちらでもない、の何れかとなるように、独立して電流を印加可能とされている。例えば、コイル823-1,823-2には、制御装置103で独立に制御された電流が印加できるよう構成されている。例えば、制御装置103は、コイル823-1,823-2に電流を印加するか否か、印加する電流の向きおよび大きさを、コイル823-1とコイル823-2とで独立に制御できる。なお、オブジェクト102の強磁性体部821-1,821-2の面8213-1,8213-2の間の間隔は、オブジェクト61の領域611と領域612との間隔と異なることが好ましい。これにより、オブジェクト102がオブジェクト61に対して静止している状態であっても、コイル823-1,823-2に印加する電流を制御するだけで、オブジェクト102の移動方向を制御できるからである。
図38Aから図41Bに例示するように、タッチスクリーン15の面152側にオブジェクト61が配置される。この際、オブジェクト61の板面613が、タッチスクリーン15の面152に接触または近接する。タッチスクリーン15の表示入力面151にはオブジェクト102が配置される。ここで、オブジェクト102は、例えば、タッチスクリーン15の表示入力面151に接触して配置される。本形態の場合、オブジェクト102が含む筐体822-1,822-2の端部8223-1,8223-2および強磁性体部821-1,821-2の面8213-1,8213-2が、表示入力面151に接触して配置される。ただし、これは本発明を限定するものではなく、オブジェクト102と表示入力面151との間に薄いシート等の部材が介在してもよい。つまり、オブジェクト102の端部8223-1,8223-2および面8213-1,8213-2が、表示入力面151に近接して配置されてもよい。
オブジェクト102の表示入力面151側に配置される端の表面(例えば、強磁性体部821-1の面8213-1)が導電体であれば、必ずしもオブジェクト102のその他の部位の表面に導電体が配置されていなくてもよい。
オブジェクト102がさらに透明素材部(透明素材または透過性を持つ素材で構成された物)を含み、オブジェクト102がタッチスクリーンの表示入力面151に接触または近接して配置されたときに、タッチスクリーン15の利用者Uが、表示入力面151の表示内容を、当該透明素材部を介して視認可能となるようにされていてもよい。
第10実施形態およびその変形例1,2では、オブジェクト102(第2オブジェクト)が2個のオブジェクト82を含む例を示した。しかし、第2オブジェクトが3個以上のオブジェクト82を含んでいてもよい。例えば、図42に例示するように、リニアモータ型のタッチスクリーン用入力システム100’が、3個のオブジェクト82を含むオブジェクト102’(第2オブジェクト)と、オブジェクト61(第1オブジェクト)と、を有していてもよい。これらの3個のオブジェクト82を、オブジェクト82-1,82-2,82-3と表記する。第10実施形態と同様、これらのオブジェクト82-1,82-2,82-3は、各オブジェクト82-1,82-2,82-3の一方の極が表示入力面151と接触または近接するように配置されている。また、オブジェクト82-1,82-2,82-3の強磁性体部821-1,821-2,821-3の表示入力面151側に配置される面8213-1,8213-2,8213-3が、三角形(例えば、正三角形)の頂点に位置するように配置され、オブジェクト82-1,82-2,82-3が互いに固定されている。また、各オブジェクト82-1,82-2,82-3(電磁石)の極は、N極、S極、どちらでもない、の何れかとなるように、独立して電流を印加可能とされている。例えば、コイル823-1,823-2,823-3には、制御装置103で独立に制御された電流が印加できるよう構成されている。例えば、制御装置103は、コイル823-1,823-2,823-3に電流を印加するか否か、印加する電流の向きおよび大きさを、コイル823-1とコイル823-2とコイル823-3とで独立に制御できる。これにより、オブジェクト102’とオブジェクト61との間の磁力により、オブジェクト102’を、表示入力面151上をD101方向だけではなく、それに直交するD102方向にも自律的に移動させることもできる。
なお、本発明は上述の実施形態に限定されるものではない。その他、請求項に記載された発明を逸脱しない範囲で適宜変更が可能であることはいうまでもない。
