If the moving speed exceeds a predetermined moving speed, the control means changes the moving speed to the predetermined moving speed, calculates the moving speed of the display object on the space on the basis of the changed moving speed of the movable part, and generates and transmits a signal for changing the moving speed into the calculated moving speed.

Description

  The present invention relates to an input device that provides route guidance and the like to a user by moving itself, and an information providing method using the input device.

  Examples of the controller (corresponding to an input device) include a stick type as shown in FIGS. 1a to 1d and a button type as shown in FIGS. 2a to 2d. As shown in FIGS. 1b and 2b, the controller has a state where no force is applied, that is, a state where the controller moves X = 0 (zero position). In the case of a stick shape, the stick is tilted as shown in FIGS. 1c and 1d, and in the case of a button type, the button is translated as shown in FIGS. 2c and 2d to generate a movement amount X. The amount of movement X can be defined by an arc-shaped angle in the case of a stick-shaped controller, and by the distance moved in the case of a button-type controller. These values may be standardized so as to take values from 0 to 1 by dividing by the respective maximum movement amounts. The user can move a certain object existing in the real space or a virtual object in the virtual space using the controller.

  Some controllers have a function that generates a force by itself and a stick moves automatically and a button moves, as seen in haptic devices. As an example of such a controller, for example, there is a controller capable of bilateral control that can operate the position of an object, generate power by itself, and feed back information to the user's hand to transmit information. Exists (see Patent Document 1). There has also been developed a telexistence that can be operated while feeling an object touched by feedback by touching an object at a long distance using such a controller (Non-patent Document 1). Further, as a device that generates a feedback force by controlling and processing, there is a surgical support device that applies force without causing a doctor to feel gravity or the like (see Patent Document 2). Further, there is one that uses a feedback force for guidance (guide) and moves a controller so that the catheter reaches a target position in a medical catheter (see Patent Document 3).

  By developing these controllers, you can operate the operation target (equivalent to a display object) to be operated by tilting or moving the controller in an arbitrary direction by the generated force, and operating the user. It is possible to guide information or guide information. Specifically, if the controller can be used to move on the map, a third party such as a robot or agent will go to the right and guide further that there is a store. (Self) falls to the right, then falls further forward. Thus, the shop can be reached, that is, it can be guided to a specific position on the map. In the meantime, the user can feel the inductive force acting on the controller while putting his hand lightly on the controller. Also, let go of the controller and leave the controller that moves automatically (without permission) until the guidance ends. Is also possible.

Here, the object to be manipulated with the movement amount X of the controller (for example, in the case of a stick-like controller, the amount of inclination from a reference position (also referred to as a stationary position) described later) using a mathematical expression below. The relationship of the amount of movement of the (operation object) (for example, the movement distance on the display screen) will be described. The user can move the target object or move the map by an operation such as tilting, pushing, or moving the controller as shown in FIGS. 1a to 1d. A certain relational expression must exist between the _controller movement amount X _controller and the object velocity V _object . Otherwise, in some cases, moving the controller a little will cause the object to move faster, and in other cases, even if the controller is moved greatly, the object will move only a little, and the user will be confused. The relationship of the movement of the object with respect to the inclination and mobility of the controller is determined by a function as shown in Equation 1 below.

V _object = f (X _controller ) (Formula 1)

  In practice, it is desirable to simply make the movement amount of the controller and the speed of the object “proportional”. This is shown in Equation 2 below. C is a proportionality constant. This relationship is shown in FIG.

V _object = C (constant) x X _controller (Formula 2)

The proportional relationship of Formula 2 means that the more the user moves the controller, the faster the object in a certain space moves in proportion. Further, if both sides are differentiated with respect to time, the relationship between the acceleration a moving the _object and the moving speed dX _controller of the _controller becomes proportional as shown in Equation 3, and the relationship is shown in FIG. 3b.

a _object = C (constant) × dX _controller (Formula 3)

  This means that if the controller is tilted from the zero position (for example, the reference position) and fixed as it is, the object continues to move in the space at a constant speed. Further, when the controller is returned to the zero position at a constant speed, the object is decelerated at a constant acceleration and stopped.

  The guidance is preferably performed while satisfying the following three important conditions “synchronization condition”, “fingering prevention condition”, and “user intervention condition”. First, the definition of “synchronization condition” will be described with reference to FIGS. 4A and 4B. 4a and 4b show how the object automatically moves in the space from the starting point to the destination point. FIG. 4a shows the geographical situation from the departure point to the destination point. FIG. 4B (1) shows the relationship between the tilt of the stick-like controller that moves automatically and the time (horizontal axis). FIG. 4B (2) shows the relationship between the speed (vertical axis) and time (horizontal axis) of the object that is automatically moved at that time. FIG. 4B (3) shows the relationship between the acceleration a (vertical axis) and time (horizontal axis) of the object when the object moves from the departure point to the destination point.

  First, at the departure point, the controller is at the zero position and the object is stationary. The controller gradually tilts automatically at a constant speed toward the destination point, and the map scrolling speed increases at a constant acceleration in proportion to the tilt. The controller tilts to the maximum and the map continues to scroll and move at a certain maximum speed.

  When approaching the destination point, the controller gradually starts to return to the original zero position at a constant speed, and the scroll speed to the destination point is decelerated at a constant acceleration accordingly. It is a necessary condition that the moment that the controller scrolls to the destination point is the “synchronized state” (simply called “synchronization”) that the controller returns to the original position and the speed stops. As a result, the user can experience a feeling of acceleration or a feeling of deceleration without looking at the numerical value of the speed displayed on the display screen. Of course, at the destination point, it is assumed that the moving speed of the object “suddenly” does not become zero but continuously changes to zero. This is called a “synchronization condition”. It is theoretically possible to realize this synchronized world view if the user does not apply excessive irregular force to the controller for a series of movements. This is because it is possible to calculate in advance when and how much the vehicle decelerates before it reaches the destination.

  Next, the definition of “fingering prevention condition” will be described. For safe operation of the controller, it should be avoided that the controller moves freely and rapidly. This is because, as shown in FIG. 5, the user suddenly moves greatly and the user stabs his finger or the finger is pinched by the button, and the user is surprised during the operation. Furthermore, even in the sense of directing movement as a product of a controller, if it moves quickly, it will be cheap. Regarding the sticking prevention technique itself for a stick controller that automatically moves, a technique in which a sensor is attached to a controller as shown in Non-Patent Document 2 below has been proposed. That is, when the sensor detects that the user's finger or the like is not touching the controller, the function of the controller's stick moving freely is stopped.

  However, when the user releases his / her hand from the controller as in the above-described sensor, the controller stops moving and the guidance stops, so that the opportunity for using the guidance function is limited. In other words, in order to reproduce the guidance, the user always has to touch the controller all the time, and if this is forced, the threshold of the use of the guidance function itself becomes high, and the user is less motivated to use it. End up.

Therefore, regardless of whether the hand is touching the controller or away from the controller, the controller moves automatically (selfishly) to provide guidance. However, in order to prevent a finger, etc., it is considered that the speed should not be higher than a predetermined speed dXmax determined in advance. When this is defined by Equation 4, if the speed at which the _controller moves is a dX _controller , the following Equation 4 must be satisfied. This is referred to as “fingering prevention condition”.

| DX _controller | ≦ | | dXmax _controller | (Formula 4)

  Guidance from the starting point to the destination point is performed by automatic control of the controller while satisfying Equation 4 of the “tip finger prevention condition” and maintaining the relationship of Equation 2. Since the speed of movement of the controller means acceleration of the movement speed of the map, the movement of the map cannot be accelerated or decelerated rapidly. Therefore, in order to satisfy the above-mentioned “synchronization condition” at the same time, when the vehicle approaches the destination point, it starts to decelerate ahead of time, so even if the controller returns slowly, the speed is just zero at the destination point. However, it is possible to calculate for automatic operation by predicting to return in synchronization with the zero position.

  The last condition “user intervention condition” will be described. It has the property of allowing the user to intervene in a new operation for a “half-forced” state, that is, a controller that moves automatically (selfishly) rather than “full” forced guidance. As a result, even if the map is moving to the right during the guidance, the user is interested in the surrounding area and stops the movement of the controller or moves the controller in the opposite direction to intervene in the automatic guidance. It is also possible. This is called a “user intervention condition”.

  The guidance function by the controller that satisfies the “synchronization condition” that gives the user a feeling of acceleration or deceleration, the “fingering prevention condition” for safety, and the “user intervention condition” that gives the user freedom is the most suitable for guidance. This is a setting that developers can easily assume.

  However, there are special situations where these conditions cannot be met. The special situation will be described using a specific example. By automatic control, the object is scrolled toward the destination point and arrives at the destination point a little more, and while the controller is automatically decelerating while returning to the original position, the “user intervention condition” causes the user to But unfortunately, there is a case where the controller is defeated at a stretch, the speed is increased, and the vehicle is just before the destination point. In order to arrive at the speed of 0 just at the destination point that is the aforementioned “synchronization condition”, the speed must be rapidly reduced in time. However, decelerating at a stroke here corresponds to returning the controller, which has been largely defeated by the user, from Equation 2 to the zero position all at once. This is contrary to Equation 4 of “Fingering prevention condition”.

  On the other hand, respecting Equation 4 of “Fingering prevention condition” and trying to slowly return the controller to the original position, the controller itself is in front of zero while the controller that is largely tilted slowly returns to the zero position. Since it has fallen to the position, scrolling continues and the speed is not zero even if it arrives just before the destination point. These mean that it may be impossible to simultaneously satisfy the “user intervention condition”, “synchronization condition”, and “finger prevention condition”.

  In view of the above problems, the present invention aims to provide an input device that satisfies these three conditions and allows the user to experience an acceleration feeling and a deceleration feeling and can be operated without a sense of incongruity, and an information providing method using the input device. And

  In order to achieve the above object, according to the present invention, there is a display object that is present in the virtual space or real space displayed on the display means and indicates the current position, and the user is given a predetermined destination point by moving the display object. An input device having a movable part that can move by a corresponding direction, distance, or angle according to the moving direction and speed of the display object. Therefore, acquisition means for acquiring movement direction information indicating the direction in which the display object is moving, and operation means for moving the movable part at a predetermined moving speed or less in conjunction with the movement direction indicated by the movement direction information. When the position of the display object is within a predetermined distance range from the destination point, the system may reduce the moving speed in the space as the destination point is approached. In conjunction with the controlled moving speed of the display object, the movable part is moved to the reference position before the start of the route guidance at the predetermined moving speed or less, and when the display object arrives at the destination point. Control means for controlling the display object and the movable part to move synchronously so that the movable part is disposed at the reference position; and accepting means for receiving an operation from the user via the movable part. And when an operation from the user is accepted during the route guidance and the movable part moves, the control means cancels the interlocking of the moving speed of the movable part with the moving speed of the display object, In order to change the moving speed of the movable part to be arranged at the reference position, the amount of movement from the reference position of the movable part and the current position of the display object at the time when the operation is accepted The moving speed of the movable part is calculated from the information on the distance to the point using a predetermined calculation formula, and when the calculated moving speed exceeds the predetermined moving speed, the moving speed of the movable part is set to the predetermined movement. The speed is changed to a speed, and a moving speed that enables the synchronization control of the display object in the space is calculated based on the changed moving speed of the movable portion, and the calculated moving speed is changed. An input device configured to generate a control signal for transmitting the generated control signal to the system is provided. With this configuration, the user can experience a sense of acceleration and a sense of deceleration and can operate without a sense of incongruity. Here, the movable part moves by a corresponding direction, distance, or angle according to the moving direction and speed of the display object. When the display object is displayed on the display means (display or the like), for example, the display object Is moved upward in the display means, the direction corresponding to the upward direction (for example, when the movable part is placed (standing) perpendicular to the two-dimensional plane (floor), Moving in the forward direction). Moreover, a display thing means the cursor etc. which show the present positions, such as the own vehicle, in virtual space or real space, for example. Further, the predetermined calculation formula corresponds to Formula 9 described later. Further, the movement of the movable part includes not only a two-dimensional movement but also an angular movement (for example, a movement in which the joystick tilts with respect to a fulcrum). The reference position refers to, for example, the neutral position of the input device, and refers to the zero position described above.

  According to the present invention, there is a display object that is present in the virtual space or real space displayed on the display means and indicates the current position, and the user is guided to the route to the predetermined destination by moving the display object. A method of providing information in the route guidance by an input device, which is usable in a system and, as a general rule, has a movable part that moves by a corresponding direction and distance or angle according to the moving direction and speed of the display object, An acquisition step for acquiring movement direction information indicating the direction in which the display object is moving for guidance, and the movable portion is moved at a predetermined movement speed or less in conjunction with the movement direction indicated by the movement direction information. When the position of the display object is within a predetermined distance range from the operation step and the destination point, the moving speed in the space decreases as the destination point is approached. In conjunction with the moving speed of the display object controlled by the system, the movable part is moved to the reference position before the start of the route guidance at the predetermined moving speed or less, and the display object is moved to the destination point. A control step of performing synchronous control for controlling the display and the movable part to move synchronously so that the movable part is arranged at the reference position when the user arrives, and the user during the route guidance When the operation from is accepted and the movable part moves, the interlocking of the moving speed of the movable part with the moving speed of the display object is canceled, and the moving speed of the movable part for disposing at the reference position is set. In order to change the information, the amount of movement of the movable part from the reference position and the information on the distance from the current position of the display object to the destination point at the time when the operation is received are represented by a predetermined calculation formula. If the calculated moving speed exceeds the predetermined moving speed, the moving speed of the movable part is changed to the predetermined moving speed and the changed moving speed is calculated. The movement speed that enables the synchronization control of the display object in the space based on the movement speed of the part is calculated, and a control signal for changing to the calculated movement speed is generated and generated. There is provided an information providing method further comprising the step of transmitting the control signal to the system. With this configuration, the user can experience a sense of acceleration and a sense of deceleration and can operate without a sense of incongruity.

  The input device and the information providing method using the input device according to the present invention have the above-described configuration, satisfy the three conditions, and allow the user to experience an acceleration feeling and a feeling of deceleration, and to operate without a sense of incongruity. That is, according to the input device and the information providing method using the input device of the present invention, when the user arrives at a “user intervention condition” that allows the user to operate at any time by processing the guiding force in the guidance (guide) function by feedback. By allowing the controller to meet all of the “synchronization conditions” for returning to a stationary state and the “fingering prevention conditions” for safety without contradiction, the user is safe, flexible, and moves the operation target. It is possible to provide information by tactile sense.

FIG. It is a block diagram which shows an example of a structure of the input device in embodiment of this invention.

  In the embodiment of the present invention, for example, a connectable controller used in a system for performing route guidance (not shown) is targeted, a given situation is determined, and the above-described controller tilt and target ( The above-mentioned “user intervention condition” and “synchronization” which may be inherently inconsistent are added by adding a function that does not cause the transformation of Equation 1 and Equation 2 describing the relationship of the moving speed of the operation object or display object). Solve the problem so that the “Condition” and “Fingering prevention conditions” are always satisfied.

  Equations 1 and 2 express how much the controller is defeated and how fast the object moves in response to it, and within a limited time under certain conditions, Even if the constant that connects the two changes, the user can operate without much discomfort. This is described in detail below.

In this example, as a known initial value, the relationship between the movement amount of the controller and the speed of the object is a proportional relationship such as Equation 2, and is a proportional constant C ₀ . Further, when moving to the destination point automatically, it is assumed that the distance L ₀ from the current point to the destination point and the current controller inclination X _controller X ₀ are given. First, using Equation 2, the speed V _{object of the} current _{object is} calculated based on the tilted position X ₀ of the controller. This is the initial speed.

V _object = X ₀ × C ₀ (Formula 5)

Next, when the target point is reached from the “synchronization condition”, this speed V _object (initial speed) should be zero as a result _of receiving the acceleration of deceleration a, so the time t until the target point is reached is 0. It is obtained as shown in Equation 6.

t = V _object / a _object (Formula 6)

Furthermore, since the distance L ₀ must be advanced after time t, Equation 7 should be satisfied.

L ₀ = V _object × t + 1/2 × a _object × t ² (Formula 7)

These equations 6 and Equation 7, V _object has already been found in Equation 5, the variables do not know other both are obtained because only two of t and a _{target object.}

a _object =-(V _object ) ² / (2L ₀ )
= − (X ₀ × C ₀ ) ² / (2L ₀ ) (Formula 8)

The acceleration decelerating can be obtained from Equation 8. From the acceleration to be decelerated, Equation 3 can be used to calculate how fast the _controller should return to the zero position with the dX _controller .

dX _controller = a _object / C ₀
= − (X ₀ × C ₀ ) ² / (2L ₀ ) / C ₀
= −X ₀ ² C ₀ / (2L ₀ ) (Formula 9)

The moving speed dX _controller of the _controller must satisfy Equation 4 of “Fingering prevention condition”. In the present invention, it is assumed that the above-mentioned special conditions are satisfied. Under the conditions, it is a feature of the present invention that the constant C in the formula 2 is changed to satisfy the formula 4. In this example, the condition is not satisfied, | dX _controller |> | dXmax _controller | In this case, the value of the dX _controller is set as the dXmax _controller as shown in Equation 10.

if | dX _controller |> | dXmax _controller |
dX _controller = dXmax _controller (Formula 10)

As a result, the speed dX at which the controller automatically moves satisfies the “finger prevention condition” because it moves only slower than the value dXmax determined in advance by the controller developer (user) under any circumstances. That is, as dX _controller = dXmax _controller , the new constant C _new must be obtained instead of the old constant C ₀ satisfying Equations 2 and 3 with this new dX _controller . Since the relation of dX _controller = −X ₀ ² C ₀ / (2L ₀ ) is already known from Expression 9, the new constant C _new satisfies the following Expression 11.

dX _controller = dXmax _controller = −X ₀ ² C _new / (2L ₀ ) (Formula 11)

Therefore, a new constant C _new is obtained from Equation 11 as Equation 12.

C _new = -2L ₀ (dXmax _controller ) / X ₀ ² (Formula 12)

If this new C _new is used to go to the destination so that the relationship between the position of the controller and the moving speed of the object at that time satisfies Expression 13, the “synchronization condition” is satisfied.

V _object = C _new × X _controller (Formula 13)

The procedure described above is summarized in the flowchart of FIG. As shown in FIG. 6, the current controller position X _controller = X ₀ , the distance L to the destination point L = L ₀ , and the controller's proportional constant C = C ₀ (step S601). The current speed V of the _{target object} is calculated from the position X _controller of the current _controller (step S602). Since the distance L ₀ travels from the calculated speed V _object until it stops at the speed 0, a deceleration acceleration a _{object is} calculated (step S603). A controller speed dX _controller is calculated from the calculated acceleration and Equation 3 (step S604). It is determined whether or not Equation 4 is satisfied (step S605). If not, the controller speed dX _controller is calculated according to equations 10 and 11 (step S606). Then, a new proportionality constant C _new is calculated by Equation 12 (step S607). Next, the speed V _{object of the object} is calculated by Equation 13 (step S608). Then, the controller is moved by the amount corresponding to the dX _controller , and the map displayed on the display means is scrolled by the amount corresponding to the V _object (step S609). When the map is scrolled, for example, a control signal for scrolling may be generated on the controller side, and the generated control signal may be transmitted to the system side that performs route guidance (not shown).

  (1) to (6) in FIG. 7 show a state in which the user further defeats the controller when the scroll of the map is decelerated near the destination and the controller is returning to the zero position in the automatic guidance. It is the graph shown on the time axis. 7 (1) and (2) show the relationship between the distance to the destination (vertical axis) and time (horizontal axis), and FIG. 7 (3) and (4) show the controller movement amount X (vertical). (5) and (6) in FIG. 7 are graphs showing the relationship between the moving speed dX (vertical axis) and time (horizontal axis). Has been. (1), (3), and (5) in FIG. 7 show a case where the user slightly defeats the controller, and (2), (4), and (6) in FIG. This shows the case where the controller is largely defeated.

  A case where the user knocks down the controller a little will be described. As shown in (1) of FIG. 7, since the vehicle decelerated to the destination with a negative acceleration, the distance to the destination changed with a parabolic lower right. Therefore, the user intervened and the controller was suddenly advanced, so the vehicle rapidly decelerated with a sharper parabola and arrived at the destination point earlier. (3) in FIG. 7 shows a state in which the movement amount X is suddenly increased due to the user's intervention when the controller is about to return to the zero position in proportion to time, due to the user's intervention. . In FIG. 7 (5), it means the inclination of the line in FIG. 7 (3). After the intervention, it can be seen that the speed dX has a larger absolute value.

  In (2), (4), and (6) of FIG. 7, user intervention is similarly entered, but this is a case where the user has largely defeated the controller. As can be seen from Equation 10, since the upper limit of the absolute value of dXmax is determined, as shown in (4) and (6) of FIG. The downward slope does not exceed dXmax. Therefore, as shown in (2) of FIG. 7, it takes more time than usual to reach the destination.

  Here, an example of the configuration of the controller (input device) 800 according to the embodiment of the present invention will be described with reference to FIG. As shown in FIG. 8, the acquisition unit 801 acquires movement direction information indicating the direction in which the object (display object) is moving for route guidance. Here, the moving direction information means, for example, information on the moving direction of the object on the coordinate axis with the position of the displayed object as the origin when the object is displayed on a display means (display or the like). . The operation unit 802 determines a movable unit (for example, a stick portion gripped by the user in the case of a stick-shaped controller) that forms part of the controller 800 in conjunction with the movement direction indicated by the acquired movement direction information. The moving speed is less than or equal to (dXmax).

When the position of the target object falls within a predetermined distance range from the destination point, the control unit 803 moves the target speed controlled by a system (not shown) so that the moving speed in space decreases as the target point is approached. The moving part is moved to a reference position before the start of route guidance at a predetermined moving speed or less, and the moving part is arranged at the reference position when the object arrives at the destination point. The movable part is controlled to move synchronously. The accepting unit 804 accepts an operation from the user via the movable part. Here, when the operation from the user is accepted during the route guidance and the movable part moves, the control unit 803 cancels the interlocking of the moving speed of the movable part with the moving speed of the object, and arranges it at the reference position. In order to change the moving speed of the movable part for the purpose, the amount of movement X from the reference position of the movable part and the information on the distance L ₀ from the current position of the target object to the destination point at the time when the operation is accepted are predetermined calculation The moving speed of the movable part is calculated by the equation, and when the calculated moving speed exceeds the predetermined moving speed, the moving speed of the moving part is changed to the predetermined moving speed and the changed moving speed of the moving part is set. Based on this, it calculates a moving speed that enables synchronization control of the object in space, generates a control signal for changing to the calculated moving speed, and transmits the generated control signal to a system (not shown) Do Than is. In the system that has received the control signal, the moving speed of the object displayed on the display means is changed based on the signal to display the object at the changed moving speed.

  In the input device and the information providing method using the input device according to the present invention, the user can experience a feeling of acceleration and deceleration and can operate without a sense of incongruity. This is useful for providing methods.

Control means for controlling the display object and the movable part to move in synchronization with each other,
Receiving means for receiving an operation from the user via the movable part,
When an operation from the user is accepted during the route guidance and the movable part moves,
The control means cancels the linkage of the moving speed of the movable part with respect to the moving speed of the display object, and changes the moving speed of the movable part for disposing at the reference position. The moving speed of the movable part is calculated by calculating the moving speed of the movable part by using a predetermined calculation formula based on the amount of movement from the position and the information on the distance from the current position of the display object to the destination point when the operation is accepted. Is higher than the predetermined moving speed, the moving speed of the movable part is changed to the predetermined moving speed, and the display object in the space is changed based on the changed moving speed of the movable part. It is configured to calculate a moving speed enabling control of synchronization, generate a control signal for changing to the calculated moving speed, and transmit the generated control signal to the system Input device. A display object that exists in the virtual space or the real space displayed on the display means and indicates the current position, and can be used in a system that guides the route to the predetermined destination point by moving the user. As an information providing method in the route guidance by an input device having a movable part that moves by a corresponding direction and distance or angle according to the moving direction and speed of the display object,
An acquisition step of acquiring movement direction information indicating a direction in which the display object is moving for the route guidance;
An operation step of moving the movable part at a predetermined moving speed or less in conjunction with a moving direction indicated by the moving direction information;
When the position of the display object is within a predetermined distance range from the destination point, the movement speed in the space decreases as the destination point is approached. The movable portion is moved to the reference position before the start of the route guidance at the predetermined moving speed or less, and the movable portion is arranged at the reference position when the display object arrives at the destination point. And a control step for synchronous control for controlling the display object and the movable part to move synchronously,
When an operation from the user is accepted during the route guidance and the movable part moves, the interlocking of the moving speed of the movable part with the moving speed of the display object is canceled and arranged at the reference position. In order to change the moving speed of the movable part, information on the amount of movement of the movable part from the reference position and the distance from the current position of the display object to the destination point at the time when the operation is accepted is a predetermined calculation formula. To calculate the moving speed of the movable part, and when the calculated moving speed exceeds the predetermined moving speed, the moving speed of the movable part is changed to the predetermined moving speed and the changed movable Based on the moving speed of the part, the moving speed that enables the synchronization control of the display object in the space is calculated, and a control signal for changing to the calculated moving speed is generated Further comprises information providing method of the generated said control signal sending to the system.
