[Embodiment 1]
The simulator device 1 according to the first embodiment is a flight simulator for training aircraft operation, for example, and is a device that simulates the flight situation of an aircraft. The simulator device 1 is not limited to a flight simulator, and is not particularly limited as long as it is a simulator device that simulates a real space. In the following description, the description is applied to a flight simulator.

  FIG. 1 is a schematic configuration diagram schematically illustrating a simulator device according to the first embodiment. FIG. 2 is a block diagram illustrating the simulator device according to the first embodiment. FIG. 3 is a flowchart illustrating a control operation of the simulator device according to the first embodiment.

  As shown in FIG. 1, the simulator device 1 includes an operation unit 10 for maneuvering an aircraft, a display unit 11 that displays an external space simulated by the aircraft, a seat unit 12 on which a pilot sits, an operation unit 10 and a display. And a control unit 13 connected to the unit 11.

  The operation unit 10 includes various operation buttons, an operation lever, and the like. When the operator operates the operation unit 10, an operation signal is input to the control unit 13. When the operation signal is input, the control unit 13 simulates the operation of the aircraft based on the input operation signal.

  The display unit 11 displays a two-dimensional display image generated by the control unit 13. The operator operates the operation unit 10 while visually recognizing the display image displayed on the display unit 11.

  The seat portion 12 can be seated by a plurality of pilots. For example, a right seat positioned on the right side with respect to the traveling direction of the aircraft and a left seat positioned on the left side with respect to the traveling direction are provided. It is done.

  The control unit 13 generates a display image to be displayed on the display unit 11 based on the operation signal input from the operation unit 10. Here, the control unit 13 generates a two-dimensional display image from three-dimensional data that is three-dimensional virtual space data simulating the real space in order to simulate the flight status of the aircraft. That is, the control unit 13 generates a display image by three-dimensional computer graphics (3DCG: Three-dimensional computer graphics).

  When generating a display image by 3DCG, the control unit 13 sets a predetermined position in the three-dimensional virtual space as a viewpoint position (also referred to as an eye point) P, and generates a display image using the viewpoint position P as a reference. Here, the predetermined viewpoint position P is substantially the same position as the viewpoint position P of the operator sitting on the seat portion 12. The viewpoint position P is normally a fixed position, but can be moved in the vibration event described below.

  In such a simulator device 1, when the operator sitting on the seat unit 12 operates the operation unit 10 while viewing the display unit 11, the control unit 13 is based on an operation signal input from the operation unit 10. A display image is generated from the three-dimensional data. At this time, the control unit 13 generates a display image on the basis of the viewpoint position P so that the viewpoint position P of the operator sitting on the seat unit 12 becomes the viewpoint position P of the three-dimensional virtual space.

  Here, the control unit 13 can execute a vibration event that simulates an aircraft vibration event that occurs in the real space. This vibration event is executed, for example, by operating a vibration event generation button (not shown). The vibration event is an irregular event of the aircraft, for example, an event that simulates a vibration event such as a failure occurrence event. A plurality of types of vibration events are prepared according to the generated vibration event.

  The control unit 13 oscillates the viewpoint position P and generates a display image corresponding to the oscillating viewpoint position P when a vibration event occurs. Here, the control unit 13 causes the amplitude of the vibrating viewpoint position P to vibrate with an amplitude larger than the amplitude of the vibration event occurring in the real space. Further, the control unit 13 causes the vibration direction of the viewpoint position P to vibrate so as to be the same as the vibration direction of the vibration event that occurs in the real space. Here, the vibration direction includes the aircraft traveling direction (axial direction of the roll axis), the aircraft width direction orthogonal to the traveling direction (pitch axis axial direction), and the aircraft vertical direction orthogonal to the traveling direction and width direction ( 3 directions of the yaw axis), or a combination of these three directions as appropriate, which is not particularly limited.

  Next, the control operation of the simulator device 1 according to the first embodiment will be described with reference to FIG. In the simulator device 1, the control unit 13 generates a vibration event (step S1). Then, the control unit 13 starts the vibration of the viewpoint position P so as to be a vibration corresponding to the vibration event in which the viewpoint position P in a fixed state is generated (step S2: viewpoint vibration step). And the control part 13 produces | generates a display image from three-dimensional data according to the viewpoint position P which vibrates (step S3: image generation step). That is, the control part 13 produces | generates a display image from three-dimensional data according to the viewpoint position P from which a position changes with progress of time. Then, the control unit 13 displays the generated display image on the display unit 11 (step S4). Subsequently, the control unit 13 determines whether or not the vibration event has ended (step S5). Here, the control unit 13 uses the end of the vibration event as a determination condition, for example, that the vibration event of the aircraft has been eliminated by the operator. When the control unit 13 determines that the vibration event has ended (step S5: Yes), the viewpoint position P is fixed to the original position, that is, the viewpoint position P becomes the viewpoint position P of the pilot sitting on the seat unit 12. (Step S6), and the control operation is terminated. On the other hand, when determining that the vibration event has not ended (step S5: No), the control unit 13 proceeds to step S3 again and repeatedly executes step S3 to step S5 until the vibration event ends.

  As described above, according to the first embodiment, the control unit 13 can display a display image on the display unit 11 such that the viewpoint position P in the three-dimensional virtual space vibrates. For this reason, it is possible for the operator who visually recognizes the display unit 11 to visually experience vibration with high reality. Note that when the viewpoint position P is vibrated, the 3DCG program for generating the display image may be modified by the control unit 13, so that it can be applied inexpensively in the existing simulator device 1.

  In the first embodiment, the control unit 13 generates a display image with the center of the display unit 11 as the origin. However, when the vibration event occurs, the control unit 13 sets the origin to other than the center of the display unit 11. By setting, the movement of only the viewpoint position P in the three-dimensional virtual space can be complemented, and a realistic vibration can be experienced visually.

  Further, according to the first embodiment, the control unit 13 sets the amplitude of the oscillating viewpoint position P to be larger than the amplitude of the vibration event that occurs in the real space, so that the driver who visually recognizes the display unit 11 can recognize it. On the other hand, the fact that it is vibrating can be properly communicated visually.

  Further, according to the first embodiment, the control unit 13 sets the vibration direction of the viewpoint position P to the same direction as the vibration direction of the vibration event that occurs in the real space, so that the vibration of the viewpoint position P and the real space The vibration can be matched. For this reason, the driver who visually recognizes the display unit 11 can experience a vibration with higher reality visually.

  In the first embodiment, the control unit 13 sets the vibration direction of the viewpoint position P to the same direction as the vibration direction of the vibration event that occurs in the real space, but if the vibration direction increases the reality, the viewpoint position P The vibration direction may be different from the vibration direction of the vibration event, and is not particularly limited.

The vibration unit 21 is connected to the control unit 13, and the control unit 13 vibrates the vibration unit 21 together with the vibration of the viewpoint position P when a vibration event occurs. Here, the control unit 13 causes the vibration direction of the vibration unit 21 to vibrate in the same direction as the vibration direction of the viewpoint position P when a vibration event occurs. For this reason, the control unit 13 vibrates the vibration direction of the vibration event occurring in the real space, the vibration direction of the viewpoint position P, and the vibration direction of the vibration unit 21 in the same direction.

  As described above, according to the second embodiment, not only a visual vibration feeling but also a tactile vibration feeling can be given to the operator sitting on the seat portion 12 by the vibration portion 21. For this reason, it is possible for the operator to experience more realistic vibrations visually and by touch.
