Furthermore, the operating system is used for operating games, driving simulators, and robots. The operating system OS disclosed in this application described in the drawings will be described below with reference to the drawings.

<System structure example> FIG. 1 is a schematic three-dimensional diagram showing an example of the appearance of the operating system OS disclosed in the present application. The operating system OS illustrated in FIG. 1 shows a structure example using an operating device 1, a main device 2, and a display device 3. The operating device 1 is a scroll mouse that accepts an operator's operation. The operator can perform operations such as pressing and rotating the operating device 1. The main device 2 is a device such as a personal computer or a home game console connected to the operating device 1, and executes computer programs such as game programs, business programs, and driving simulator programs. The display device 3 is a monitor connected to the main device 2, and includes a display unit 30 that displays images.

The operating device 1 includes a housing 10, a pressing operation unit 11 such as a mouse button that accepts a pressing operation by an operator, and a rotating operation unit 12 such as a mouse wheel that accepts a rotating operation by an operator. The rotating operation unit 12 accepts not only a rotating operation but also a pressing operation (so-called click). The rotating operation unit 12 is accommodated in the housing 10 except for the part that the operator touches for operation.

<Example of operating device structure> Figure 2 is a schematic perspective view showing an example of the internal structure of the operating device 1 disclosed in this application. Figure 3 is a schematic front view showing an example of the internal structure of the operating device 1 disclosed in this application. Figure 4 is a schematic perspective view showing an example of the internal structure of the operating device 1 disclosed in this application. Figure 2 is a perspective view of the frame 10 of the operating device 1, showing the positional relationship between the frame 10 and the main parts of the internal structure in a manner that can be identified. Figures 3 and 4 show the frame 10 of the operating device 1 removed, showing the main parts of the internal structure in a manner that can be identified.

Various structures such as a rotation operation unit 12, a rotation shaft 13, a load unit 14, a push detection unit 15, and a control panel (control unit) 16 are accommodated in the housing 10.

The rotating shaft 13 is installed in a penetrating state at the rotation center of the rotating operating part 12. The rotating shaft 13 rotates in the circumferential direction as the rotating operating part 12 rotates. An angle detection part 120 as an encoder is installed on one end side of the rotating shaft 13 penetrating the rotating operating part 12. The angle detection part 120 detects the rotation angle of the rotating shaft 13 and encodes the detected rotation angle. A pressing member 121 and a load part 14 are installed on the other end side of the rotating shaft 13, and a central detection part (detection part) 122 using a tactile switch is arranged below the pressing member 121. The pressing member 121 is a member for pressing the central detection portion 122 disposed below, and is formed of an arc-shaped thin plate so as to cover the lower portion of the substantially cylindrical load portion 14 .

The load portion 14 has a substantially cylindrical outer shape and includes a structure such as a fluid gate 140. The fluid gate 140 is a mechanism for generating a load by the viscosity of a magnetic viscosity fluid (hereinafter referred to as MR fluid) 140a relative to the rotation of the rotating shaft 13. The details of the fluid gate 140 will be described later.

The rotation operation unit 12 receives a rotation operation with the rotation axis 13 as the rotation center and a pressing operation from the top to the bottom perpendicular to the rotation axis 13 from the operator. When the rotation operation unit 12 is pressed, the rotation operation unit 12, the rotation axis 13, the angle detection unit 120, the pressing member 121 and the load unit 14 are integrated and move downward, and the central detection unit 122 is pressed by the lower surface of the pressing member 121. FIG. 3 shows a state in which the rotation operation unit 12 is pressed downward and the central detection unit 122 is pressed by the lower surface of the pressing member 121. When the rotation operation portion 12 is released from being pressed, the rotation operation portion 12 , the rotation shaft 13 , the angle detection portion 120 , the pressing member 121 and the load portion 14 return to their original positions.

The pressing detection unit 15 is a micro switch disposed on both sides of the rotating operation unit 12, and detects the pressing operation of the pressing operation unit 11, i.e., the so-called clicking operation. In the following description, as needed, the pressing detection unit 15 that detects the pressing operation of the pressing operation unit 11 corresponding to the so-called left click is represented as the left detection unit 150, and the pressing detection unit 15 that detects the pressing operation of the pressing operation unit 11 corresponding to the so-called right click is represented as the right detection unit 151.

The control board 16 is formed by mounting chips such as integrated circuits and electronic components on a substrate, and controls various structures such as the fluid gate 140.

The fluid gate 140 will be described below. FIG. 5 is a schematic cross-sectional view schematically showing an example of the internal structure of the fluid gate 140 of the load portion 14 included in the operating device disclosed in the present application. FIG. 6 is a schematic cross-sectional exploded perspective view showing an example of the internal structure of the fluid gate 140 of the load portion 14 included in the operating device disclosed in the present application. The fluid gate 140 of the load portion 14 includes a container 140b that is roughly cylindrical with a bottom, and the rotating shaft 13 is inserted through the center of one of the bottom surfaces of the container 140b. In the following description, for convenience, the upper side of FIG. 5 and FIG. 6 is set as the upper side, and the lower side is set as the lower side for description. Furthermore, the up and down directions are names for the convenience of description and do not limit the installation direction. The container 140b includes: a container 140b1 having a bottom and a substantially cylindrical shape with an open upper bottom side, and a substantially disk-shaped cover 140b2 that closes the opened opening of the container 140b1. A portion of the rotating shaft 13 is rotatably accommodated in the container 140b, and one end side of the rotating shaft 13 protrudes from the center of the cover 140b2 of the container 140b and is mounted on the rotating operation part 12. A first bearing part 140c such as a roller bearing is arranged near the center of the cover 140b2 through which the rotating shaft 13 is inserted, and the rotating shaft 13 is rotatably supported. The other end of the rotating shaft 13 is rotatably supported by a second bearing portion 140d such as a sliding bearing installed on the inner surface of the lower bottom side of the receiving body 140b, and is accommodated in the receiving body 140b. A substantially circular plate-shaped dish portion 130 is formed on the rotating shaft 13 in a manner extending radially, and the dish portion 130 is accommodated in the receiving body 140b. On the lower surface of the dish portion 130, a cylindrical rotor 131 is installed by screwing, bonding, or the like, or is formed integrally with the dish portion 130, and rotates together with the dish portion 130.

A fluid chamber 140e is formed inside the container 140b, and the fluid chamber 140e is filled with the MR fluid 140a in such a manner that the MR fluid 140a contacts the components such as the disk portion 130 and the rotor 131 of the rotating shaft 13. Since the MR fluid 140a formed in the fluid chamber 140e contacts the disk portion 130 and the rotor 131 of the rotating shaft 13, the viscosity of the MR fluid 140a becomes a load that hinders the rotation of the rotating shaft 13. Below the rotor 131, a magnetic field generating portion 140f such as a coil is arranged in such a manner that it is wound around the rotating shaft 13, and the magnetic field generating portion 140f generates a magnetic field for controlling the viscosity of the MR fluid 140a. Furthermore, a magnetic yoke 140g is disposed inside the container 140b in order to efficiently control the viscosity of the MR fluid 140a using the magnetic field generated by the magnetic field generating unit 140f.

By using the fluid gate 140 illustrated in FIG. 5 and FIG. 6 , the container 140b can be configured as a container 140b1 and a cover 140b2, and the rotating shaft 13 is passed only on the cover 140b2 side, thereby configuring the roller bearing only as the first bearing portion 140c. In this way, the fluid gate 140 included in the operating device disclosed in this application can reduce the number of parts. Furthermore, the fluid gate 140 included in the operating device disclosed in this application can also adopt a structure in which the inner bottom surface of the lower bottom side of the container 140b1 is provided with a concave and convex structure to support the rotating shaft 13 rotatably, thereby removing the second bearing portion 140d, thereby reducing the number of parts.

The MR fluid will be described below. FIG. 7 and FIG. 8 are diagrams schematically showing the characteristics of the MR fluid 140a (magnetic viscosity fluid) used in the fluid gate 140 of the load portion 14 included in the operating device 1 disclosed in the present application. FIG. 7 conceptually shows the MR fluid 140a in a state where it is not affected by a magnetic field, and FIG. 8 conceptually shows the MR fluid 140a in a state where a magnetic field is generated. The MR fluid 140a is a functional fluid in which fine particles of a ferromagnetic material with a diameter of 1 μm to 10 μm are dispersed in a liquid such as water or oil. As shown in FIG. 7 , the fine particles are uniformly dispersed in the liquid when not affected by a magnetic field. As shown in Figure 8, when subjected to a magnetic field, the ferromagnetic particles are magnetized and attract each other, forming clusters, which increases the viscosity of the liquid. The degree of cluster formation can be controlled by the magnetic field, so the viscosity can be adjusted by controlling the magnetic field.

FIG9 is a graph showing the characteristics of the MR fluid 140a (magnetic viscosity fluid) used in the fluid gate 140 of the load portion 14 included in the operating device 1 disclosed in the present application. FIG9 shows the relationship between the intensity of the magnetic field on the horizontal axis and the viscosity of the MR fluid 140a on the vertical axis. As shown in FIG9, the magnetic field and the viscosity are in a one-to-one correspondence, so the viscosity can be adjusted by controlling the magnetic field.

<Control system structure example> Next, the control system of the operating system OS disclosed in the present application is described. FIG. 10 is a block diagram showing an example of the structure of the operating system OS disclosed in the present application. The control board 16 included in the operating device 1 is a control unit equipped with various integrated circuits such as a central control unit 160, a perceptual control unit 161, and a perceptual recording unit (recording unit) 162. The central control unit 160 is a processor such as a central processing unit (CPU) that controls the entire device, and is connected to various circuits mounted on the control board 16, various mechanisms such as the rotary operating unit 12, etc. by signal lines. The perceptual control unit 161 is an integrated circuit that controls the load on the rotation of the rotary operating unit 12 by controlling the magnetic field applied to the fluid gate 140. The interpretation control unit 161 controls the turning operation unit 12 based on various information recorded in the interpretation recording unit 162, thereby, for example, performing interpretation so that the operator can feel the feeling of driving on various roads. The interpretation recording unit 162 is a memory that records the interpretation information indicating the interpretation mode, which indicates the control method used for the interpretation. For example, when the interpretation mode is applied to a racing game, it is information for performing interpretation of simulating the steering load on various road surfaces such as a road surface that becomes an icy slope due to freezing, a road surface in a muddy state, and an unpaved and uneven road surface. In the derivation mode, magnetic field information representing a magnetic field pattern for controlling the fluid gate 140 is included.

The pressing operation unit 11 includes various structures for inputting the left detection unit 150 and the right detection unit 151 for detecting the pressing operation. Furthermore, the pressing operation unit 11 includes a pressing input circuit 152, which encodes the pressing operation detected by the left detection unit 150 and the right detection unit 151 and outputs it to the central control unit 160 as an input signal.

The rotation operation unit 12 includes various structures for input, such as an angle detection unit 120 for detecting a rotation angle, a central detection unit 122 for detecting a pressing operation, etc. Furthermore, the rotation operation unit 12 includes a rotation input circuit 123, which encodes the rotation angle detected by the angle detection unit 120 and the pressing operation detected by the central detection unit 122, and outputs them to the central control unit 160 as input signals.

The load unit 14 includes various structures such as a fluid gate 140 and a magnetic field control unit 141. The magnetic field control unit 141 is a driver as described below, that is, the self-deduction control unit 161 receives a magnetic field control signal, and controls the magnetic field applied to the MR fluid 140a by the magnetic field generating unit 140f based on the received magnetic field control signal. By controlling the magnetic field applied to the MR fluid 140a, the viscosity of the MR fluid 140a is controlled to control the load on the rotation of the rotation operating unit 12.

Furthermore, the operating device 1 includes an operating connection portion 163 as an interface connected to the main device 2 using a communication line.

The main device 2 includes various structures such as a main body control unit 20, a main body recording unit 21, a main body connection unit 22, and a display control unit 23. The main body control unit 20 is a processor such as a CPU that controls the entire main body device 2. The main body recording unit 21 is a circuit such as a non-volatile memory and a volatile memory that record various information. Various programs and data such as game programs are recorded in the main body recording unit 21. The main body connection unit 22 is an input interface for connecting input devices such as a mouse and a keyboard. In this application, an example of connecting an operating device 1 as an input device is shown. Furthermore, when the operating device 1 disclosed in this application is connected as an input device, the body connection unit 22 also functions as an output interface for outputting various signals to the operating device 1. The display control unit 23 is an interface for outputting image signals to the display device 3 and controlling images displayed on the display device 3.

The display device 3 includes a display unit 30 using a panel such as a liquid crystal panel or an organic electroluminescence (EL) panel for displaying images, and displays images on the display unit 30 based on image signals input from the main device 2. That is, the main device 2 displays images on the display unit 30, and the images include images of an operating body that operates based on the rotation operation received by the rotation operation unit 12 and an operating environment of the operating body. The operating body displayed on the display unit 30 is, for example, a virtual vehicle, and the operating environment of the operating body is, for example, a road surface on which the virtual vehicle travels. For example, when the mouse wheel is rotated in a first direction toward the fingertips, an image of the virtual vehicle turning to the left is displayed; when the mouse wheel is rotated in a second direction opposite to the first direction, an image of the virtual vehicle turning to the right is displayed.

One form of processing of various devices included in the operating system OS disclosed in this application configured as described above is described. The main device 2 executes programs such as game programs and driving simulator programs recorded in the main recording unit 21 under the control of the main control unit 20. In this application, an example of executing a program such as a driving game in which an operator performs input operations using the operating device 1 is described.

The main device 2 executes the driving game program under the control of the main control unit 20, and outputs an image signal from the display control unit 23 to the display device 3. The main device 2 outputs the image signal to display the virtual vehicle as the operating body and the road surface as the operating environment on which the virtual vehicle is driving on the display unit 30 of the display device 3. In addition, the main control unit 20 of the main device 2 outputs driving information indicating driving on the road surface displayed on the display unit 30 from the main connection unit 22 to the operating device 1.

The central control unit 160 of the operating device 1 receives the input of driving information using the operation connection unit 163, and sends the driving information to the interpretation control unit 161. The interpretation control unit 161 sends identification information for identifying the interpretation mode corresponding to the received driving information to the interpretation control unit 161. The interpretation control unit 161 reads the interpretation information recorded in association with the received identification information from the interpretation recording unit 162. Furthermore, based on the read interpretation information, the interpretation control unit 161 outputs magnetic field information representing the magnetic field mode for controlling the viscosity of the fluid gate 140 to the magnetic field control unit 141 included in the load unit 14. The magnetic field control unit 141 forms a magnetic field based on the magnetic field information to control the viscosity of the fluid gate 140 .

The fluid brake 140 is controlled based on the interpretation mode corresponding to the road surface on which the virtual vehicle is traveling. Therefore, the operator will feel the load corresponding to the road surface displayed on the display unit 30.

The operation of the rotation operation unit 12 by the operator is detected by the angle detection unit 120 and the center detection unit 122. The angle detection unit 120 and the center detection unit 122 detect the rotation angle and the pressing operation of the rotation operation unit 12.

The central control unit 160 receives an operation signal indicating the operation input detected by the angle detection unit 120 and the central detection unit 122 via the rotation input circuit 123. The central control unit 160 outputs the received operation signal from the operation connection unit 163 to the main device 2.

The main device 2 advances the game based on the operation signal received by the main body connection unit 22.

Next, another structural example of the fluid gate 140 is described. FIG. 13 is a schematic explanatory diagram schematically showing an example of the internal structure of the fluid gate 140 of the load portion 14 included in the operating device disclosed in the present application.

As described above, the operating system OS disclosed in this application generates a load for the rotation operation of the rotation operation unit 12 by means of the fluid gate 140. Thus, the operating system OS disclosed in this application generates a load in conjunction with a game such as a racing game, so that the operator can have a new operating feeling such as a deeper sense of immersion. The load generated by the fluid gate 140 is a passive load, and generates a new feeling of load different from the active load generated by driving the electric motor.

For example, the operating system OS disclosed in this application can also be implemented as a system of various industrial machines that integrate the operating device 1, the main device 2, and the display device 3.

Furthermore, for example, in the above-described embodiment, the load portion 14 generates a load on the rotation operation portion 12 via the rotation shaft 13 , but the present invention is not limited thereto and can be developed into various forms such as a form in which a load is directly generated by the rotation of the rotation operation portion 12 .
