Description
- 1. Field of the Invention
- The present invention relates to a seat-driving device of a simulation system, and more particularly, to a seat-driving device of a simulation system which has an improved structure in which a moving or rotation range of a seat depending on a manipulation of a user greatly increases.
- 2. Description of the Related Art
- Simulation systems provide an indirect experience to a user by artificially creating circumstances that can actually occur using computers. Examples of the simulation systems include flight simulation systems, driving simulation systems, etc. It is important for a simulation system to precisely reproduce various circumstances so that a user can feel the sense of the reality and the feeling of movement as much closely to an actual circumstance as possible. To accomplish reproduction of circumstances close to actual circumstances by simulation systems, it is very important to develop software by which a displayed image changes according to a manipulation of a user and hardware, that is, a driving mechanism, for promptly making a motion based on a mathematical model of a moving body, such as, an automobile, an airplane, etc.
- A flight simulation system for use in PCs is an example of a conventional simulation system. In the flight simulation system for use in PCs, no special mechanism for moving or rotating a simulation user is not included, and only a displayed image changes according to software. However, this flight simulation system does not provide a realistic simulation because there are no physical motions of the simulation user. To supplement this disadvantage, that is, to provide a more realistic simulation, the simulation system needs to give physical motions to the user of the simulation system. The physical motions are made by moving, rotating, or vibrating a seat for the user of the simulation system or using other methods.
- Various types of simulation systems in which a simulation user can move physically have been proposed, for example, a simulation system disclosed in U.S. Pat. No. 5,240,417. In this conventional simulation system, a seat for a user or the like is supposed to move or rotate using a motor or a hydraulic device driven according to a manipulation of the user. However, the conventional system has difficulty providing a realistic simulation because a moving or rotating range of the seat is significantly restricted.
- There remains a demand for a seat-driving device to be used in a simulation system capable of providing a more realistic simulation.
- The present invention provides a seat-driving device of a simulation system which can achieve realistic simulation by greatly increasing a moving or rotation range of a seat depending on a manipulation of a user and is applicable to simulations of various types of vehicles.
- According to an aspect of the present invention, there is provided a seat driving device of a simulation system for driving a seat on which a user of the simulation system sits, the seat driving device including a first member having a spherical surface, a second member making a relative motion with respect to the first member, two wheels rotatably coupled to the second member and rolling on and contacting the spherical surface of the first member, and two driving motors installed on the second member and connected to the wheels to rotate the wheels. The seat is installed on one of the first and second members.
- The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which:
-
FIG. 1 is a schematic cross-sectional view of a seat-driving device of a simulation system according to an embodiment of the present invention; -
FIGS. 2A through 2H illustrate rotations of a first member shown inFIG. 1 ; and -
FIG. 3 is a schematic cross-sectional view of a seat-driving device of a simulation system according to another embodiment of the present invention. - Referring to
FIG. 1 , a seat-driving device of asimulation system 1 according to an embodiment of the present invention includes afirst member 10 and asecond member 20. - The
first member 10 has a global shape. In this embodiment, thefirst member 10 has a perfect global shape. Thefirst member 10 may be manufactured of metal. Thefirst member 10 is preferably formed of engineering plastic or other lightweight materials to reduce the weight of thefirst member 10 and the rotational inertia. - A
seat 40, on which a user of thesimulation system 1 can sit, is installed within thefirst member 10. - The
first member 10 includes amanipulator 14, adisplay 11, and agyro sensor 12. - As shown in
FIG. 1 , themanipulator 14 has a control lever shape and is combined with theseat 40 so that the user of thesimulation system 1 can manipulate thesimulation system 1 on theseat 40 using themanipulator 14. Themanipulator 14 may be a manipulatable remote controller separated from theseat 40. In some cases, themanipulator 14 may not be included in thesimulation system 1. - The
display 11 is located in front of the user of thesimulation system 1 so that the user can always see the-display 11. In some cases, a sound reproducing device which can reproduce a sound corresponding to an image reproduced by thedisplay 11 may be installed together with thedisplay 11. - Since the
first member 10 has a moment of inertia, it is important to know an exact rotational speed and an exact position of thefirst member 10. Hence, thegyro sensor 12 is installed within thefirst member 10. - The
first member 10 is supported by asupport 60 so as to be rotatable with respect to abottom surface 90 of a building where thesimulation system 1 is installed. A center of thesupport 60 is void to receive thesecond member 20, and an upper innercircumferential surface 67 thereof is concave with a curvature corresponding to a curvature of an outer circumferential surface of thefirst member 10. A plurality ofballs 65, which rolls and contracts the outer circumferential surface of thefirst member 10, are installed on the upper innercircumferential surface 67 of thesupport 60. - Preferably, an
upper support 50 is installed on thefirst member 10 to prevent thefirst member 10 from being detached from thesupport 60. - The
second member 20 can make a relative motion with respect to thefirst member 10. Twowheels second member 20, and twodriving motors second member 20. - The two
wheels second member 20 to be rotatable with respect to thesecond member 20 and roll on and contact the outer circumferential surface of thefirst member 10. The entire surface of each of thewheels wheels first member 10 is manufactured of a material having a high friction coefficient with respect to the outer circumferential surface of thefirst member 10, such as, compressed rubber. - Central axes of rotation of the
wheels wheels first member 10. The central axes of rotation of thewheels wheels first member 10. In other words, a straight line that connects between the center of thefirst member 10 and each of the points where thewheels first member 10 is perpendicular to the central axes of rotations of thewheels - The two
driving motors wheels - In this embodiment, the
second member 20 exists under thefirst member 10 and is installed within thesupport 60. thesecond member 20 is installed on a disk-shapedrotating support 21 fixed to thebottom surface 90 to be rotatable by ashaft 24 andbearings 25. - The
second member 20 includes a movingelement 22 and adriving source 23 for moving themoving element 22. The movingelement 22 is driven by thedriving source 23 to move between a first position that presses down on thebottom surface 90 to prevent rotation of thesecond member 20 and a second position that is separated from thebottom surface 90 to allow rotation of thesecond member 20. - A solenoid may be properly used as the
driving source 23. Other motors may also be used as thedriving source 23. - An operation and advantages of the seat-driving device will now be described in greater detail. When the user issues a command requiring rotation using the
manipulator 14, the drivingmotors wheels wheels wheels first member 10 due to a frictional force between each of thewheels first member 10 on which thewheels first member 10 is rotated, and thus theseat 40 installed in thefirst member 10 is rotated. rotational speeds and directions of thewheels first member 10 are controlled by a manipulation of themanipulator 14 or according to a pre-input program. - During simulation, images and the like are updated in real time and displayed on the
display 11, so that a user can undergo a realistic simulation. - A principle in which the
first member 10 is rotated by a rotation of thewheels FIGS. 2A through 2H .FIGS. 2A through 2H are bottom views of thesimulation system 1. Since theseat 40 installed in thefirst member 10 is rotated by a rotation of thefirst member 10, only thewheels first member 10 are illustrated inFIGS. 2A through 2H . - First, coordinate axes and rotational directions are defined for convenience of explanation. As shown in
FIG. 1 , an axis corresponding to a forward and backward direction of the user sitting on theseat 40 is defined by an x-axis, an axis corresponding to a left and right direction of the user sitting on theseat 40 is defined by a y-axis, and an axis corresponding to an upward and downward direction of the user sitting on theseat 40 is defined by a z-axis. A rotation in one direction at the center point of thefirst member 10 about the +x axis is defined by a rotation in a+rx direction, and a rotation in the other direction at the center point of thefirst member 10 about the +x axis is defined by a rotation in a −rx direction. This rotation definition rule is equally applied to the y-axis and the z-axis. - When the
wheels FIGS. 2A and 2B , thefirst member 10 rotates about the x-axis. Depending on a rotational direction of thewheels first member 10 may rotate either in the +rx direction as shown inFIG. 2A or the −rx direction as shown inFIG. 2B . - When the
wheels FIGS. 2C and 2D , thefirst member 10 rotates about the z-axis. Depending on a rotational direction of thewheels first member 10 may rotate either in a +rz direction as shown inFIG. 2C or the −rz direction as shown inFIG. 2D . - When the
first member 10 is desired to rotate about the y-axis, the movingelement 22 is moved to the second position separated from thebottom surface 90 by the drivingsource 23 included in thesecond member 20 so that rotation of thesecond member 20 is allowed. When the twowheels FIG. 2E , a difference between the moments of inertia of the first andsecond members second member 20 instead of thefirst member 10 to rotate about theshaft 24 and the rotation axis of thefirst member 10 to change as shown inFIG. 2F or 2G. When the axis about which thefirst member 10 rotates is changed as shown inFIG. 2F or 2G, the drivingsource 23 included in thesecond member 20 is re-driven to move the movingelement 22 at the second position to the first position, so that the movingmember 22 presses down on thebottom surface 90. Thus, the rotation of thesecond member 20 is prevented. - In a state where the rotation of the
second member 20 is hindered as described above, when thewheels FIGS. 2F and 2G , thefirst member 10 rotates about the y-axis. Even in this case, as in the rotation in the +rx or −rx direction, thefirst member 10 may rotate either in the +ry direction as shown inFIG. 2G or the −ry direction as shown inFIG. 2F depending on a rotational direction of thewheels - Although cases where the two
wheels FIGS. 2A through 2G , the twowheels wheel 30 is at a standstill or rotates slowly and thewheel 31 rotates in the same direction as that of thewheel 30 but at a speed greatly higher than thewheel 30 as shown inFIG. 2H , thefirst member 10 rotates along a complicate trajectory with a continuous change of the rotational axis of thefirst member 10. If the difference between the rotational speeds of the twowheels first member 10 may be rotated about a rotational axis slanting in an arbitrary direction. When the twowheels first member 10 may have a more complicate rotation trajectory than when the twowheels - Due to such a rotation of the
seat 40, a user of thesimulation system 1 experiences a rotation about one of the y-axis, the x-axis, and the z-axis or an arbitrary axis on a space defined by the axes in a coordinate established with theseat 40 as its center as shown inFIG. 1 . Thus, a more realistic simulation is achieved. - In most applied fields, such as, an automobile or motorcycle driving simulation, an airplane operating simulation, or a roller coaster, a sharp rotation about the y-axis, that is, a rolling in the right and left directions of the
seat 40, rarely occurs. Generally, the rotation about the y-axis is mixed with rotations about the other axes. Hence, a pure rotation about the y-axis may not be needed during actual simulation, because a desired rotation can be obtained from a complicate rotation (i.e., a rotation about an arbitrary axis) as described below. In the above-described applied fields, the rotatingsupport 21, the movingelement 22, and the drivingsource 23 may not be needed. -

A description of the seat-drivingdevice 201 is focused on elements different from those of the seat-driving device ofFIG. 1 . The description about the seat-driving device ofFIG. 1 is equally applied to elements-of the seat-drivingdevice 201 that are not described. Alternatively, the description about the seat-driving device ofFIG. 1 is properly modified and applied to the not-described elements of the seat-drivingdevice 201. Like reference numerals are used to indicate elements that play like technical roles. - Similar to the seat-driving device of
FIG. 1 , the seat-drivingdevice 201 ofFIG. 3 includes afirst member 210 and asecond member 220. Thefirst member 210 has a spherical surface and is fixed to abottom surface 290 of a building where a simulation system is installed. - The
second member 220 is installed to be rotatable with respect to thebottom surface 290. Twowheels second member 220 and roll on and contact the spherical surface of thefirst member 210. Thesecond member 220 includes amotor coupling portion 221, aseat coupling portion 222, and a clutch 225. - Two driving
motors wheels motor coupling portion 221. - A
seat 240 on which a user of the simulation system sits is installed on theseat coupling portion 222. - The clutch 225 is installed between the
motor coupling portion 221 and theseat coupling portion 222 and either connects or disconnects themotor coupling portion 221 and theseat coupling portion 222. An electronic clutch may be used as the clutch 225. Other well-known clutches may be used as the clutch 225. - A
display 211, which a user of the simulation system sees, is installed in front of theseat 240. Thedisplay 211 is not necessarily installed on theseat 240 but can be installed at a position where thedisplay 211 can be seen by the user of the simulation system and rotate together with a rotation of theseat 240, that is, at a position not causing a relative movement between theseat 240 and thedisplay 211. - An operation and advantages of the seat-driving
device 201 will now be described. Since thefirst member 210 is fixed onto thebottom surface 290, and thesecond member 220 can make a relative movement with respect to thefirst member 210, thewheels second member 220 are rotated on the spherical surface of thefirst member 210 by the drivingmotors seat 240 is also rotated. - A mechanism for rotating the
seat 240 is similar to what is described wit reference toFIGS. 2A through 2H . However, to rotate theseat 40 in the ry direction, in the embodiment ofFIG. 1 , thesecond member 20 is rotated without a rotation of thefirst member 10 by moving the movingelement 22 included in thesecond member 20, and the rotational axis of theseat 40 is thus changed. On the other hand, to rotate theseat 240 in the ry direction, in the present embodiment, theseat coupling portion 222 and themotor coupling portion 221 are mechanically disconnected using the clutch 225, and then thewheels motor coupling portion 221 and thewheels seat 240. - While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
- As described above, the present invention can provide a seat driving device for a simulation system which realistically simulates driving of vehicles, such as, airplanes, spacecrafts, automobiles, or motorcycles, riding of roller coasters, etc. In particular, the simulation system can embody a user's feeling of a free rotation in 3 axial directions using only two wheels, so that the structure of the simulation system is very simple.
- The present invention is applicable to games, such as, console box games or mobile games. When a user watches a movie sitting on a seat of the simulation system, he or she can enjoy more realistic images because the seat makes proper rotations depending on images. In other words, the present invention is also applicable to multi-media systems.
