Description

GAME CONTROLLER

FIELD OF THE INVENTION

The present invention relates to a system and method for a user to control the movement of an object in a video game.

BACKGROUND OF THE INVENTION

A variety of game controllers are available to enable players to control computer games, arcade games, console games, and the like. For example, a conventional computer keyboard may be used to control many games. Alternatively, a variety of joysticks are available to control game movements and actions. Some conventional game controllers include two joysticks to be manipulated by a player's thumbs in order to control game movements. There are also available more specific game controllers, such as steering wheel controllers for steering in driving games, and gun controllers for aiming and shooting in shooting games. All such game controllers may be provided with one or more buttons which may be pressed by the player to perform a specified action (e.g. shooting or jumping) within the game.

The present invention seeks to provide an alternative game control system which provides various advantages over

those of the prior art.

SUMMARY OF THE INVENTION

According to a first aspect of the present invention, there is provided a system for a user to control the movement of an object in a video game, comprising: a direction sensor arranged to sense a directional input by the user; a movement sensor arranged to sense gross movement of the user; and a processor arranged to combine the sensed directional input and the sensed movement to provide an output signal for controlling the movement of the game object, the output signal being provided such that a direction of movement of the game object varies in dependence upon the sensed directional input and a magnitude of movement of the game object varies in dependence upon the sensed movement.

A user of a system according to the present invention is required to make gross large-scale movements of their body (such as stepping, walking, running, jumping, etc.) in order to fully control movement of the game object. Thus, the user exercises whilst playing the game. Furthermore, such a system can enable a more real gaming experience than

prior art systems.

According to a second aspect of the present invention, there is provided a method for a user to control the movement of an object in a video game, comprising the steps of: providing a direction sensor and a movement sensor; using the direction sensor to sense a directional input by a user; using the movement sensor to sense gross movement of the user; and combining the sensed directional input and the sensed movement to provide an output signal for controlling the movement of the game object, the output signal being provided such that a direction of movement of the game object varies in dependence upon the sensed directional input and a magnitude of movement of the game object varies in dependence upon the sensed movement.

Other preferred features of the present invention are set out in the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS

An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 schematically illustrates a system according to a first embodiment of the present invention; and Figure 2 schematically illustrates one embodiment of a movement sensor comprising two pressure pads.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Figure 1 schematically illustrates a system 10 for a user 12 to control the movement of an object in a video game according to a first embodiment of the present invention.

The system 10 comprises a direction sensor 14, a movement sensor 16 and a processor 18. A games console 20 and a screen 22 are also shown.

The direction sensor 14 is arranged to sense a directional input by the user 12. In one embodiment, the direction sensor 14 comprises a joystick. Thus, the directional input by the user 12 is performed by the user 12 moving the joystick in a particular direction in a manner known in the art. Alternatively, the direction sensor 14 may comprise a gamepad or a steering wheel. Other known direction sensor embodiments are also contemplated within the scope of the invention.

The movement sensor 16 is arranged to sense gross movement of the user 12. Gross movement of a user is intended to be distinguished from small-scale user movement.

Examples of small-scale user movement include manipulations of gamepad controllers with a user's thumbs or normal movement of a joystick with a user's hand. Whereas, gross movement of a user includes stepping, walking, walking on the spot, jogging, jogging on the spot, running, running on the spot, skipping, skipping on the spot, jumping, dancing, kicking, etc. Thus, gross movement of the user generally involves movement of at least one of the user's entire limbs or movement of the user's torso. Furthermore, gross movement of the user is generally associated with aerobic exercise by the user.

The processor 18 is arranged to combine the sensed directional input sensed and the sensed movement in order to provide an output signal for controlling the movement of the game object. Examples of game objects are a human or animal character, or a vehicle such as a racing car.

In the embodiment of Figure 1, the direction sensor 14, the movement sensor 16 and the processor 18 are all provided in discrete, separate units. Alternatively, the direction sensor and the movement sensor could be provided in the same unit. Similarly, the processor could be provided in the same unit as either the direction sensor, the movement sensor, or both.

There is a link 24 between the direction sensor 14 and the processor 18 to enable the processor 18 to receive a signal which varies in dependence upon the sensed directional input. Similarly, there is a link 26 between the movement sensor 16 and the processor 18 to enable the processor 18 to receive a signal which varies in dependence upon the sensed movement. In addition, there is a link between the processor 18 and the games console 20 to enable the games console 20 to receive the output signal of the processor 18. The links 24, 26 and 28 are illustrated schematically by dashed lines in Figure 1. Each of the links 24, 26 and 28 may or may not be wireless.

The output signal of the processor 18 is provided such that a direction of movement of the game object varies in dependence upon the sensed directional input and a magnitude of movement of the game object varies in dependence upon the sensed movement.

The games console 20 is arranged to receive the output signal of the processor 18, and the screen 22 is arranged to display the video game graphics to the user 12.

Table 1 shows a preferred embodiment, in which the system is used to control the movement (forwards, backwards, left, right, etc.) of a game object in a typical video game.

In this embodiment, a single direction sensor (e.g. a joystick or a steering wheel) is used to jointly control the rotational and translational directions of movement of the game object. For example, the game might be a football game or a driving game in which the game object is a footballer character or a racing car respectively. In such games, when there is translational movement of the game object, the game object faces in the same rotational direction as the translational direction of movement (i.e. the footballer faces in the same direction as he is running, or the car faces in the same direction as it is driving).

Sensed directional input Null Non-zero Null No movement of Rotational movement of Sensed game object game object movement Non-No movement of Translational movement of zero game object game object

Table 1

Referring to Table 1, there is no movement of the game object when the sensed directional input is null and the sensed movement is null. For example, the footballer character will remain stationary when the user 12 is standing still and providing no directional input via the direction sensor.

In contrast, there is translational movement of the game object when the sensed directional input is non-zero and the sensed movement is non-zero. The direction of the translational movement varies in dependence upon the sensed directional input. For example, when the user 12 is running on the spot and is also providing a directional input in a particular direction, the footballer character will run through the game environment (e.g. football pitch) in a direction associated with that particular direction.

In addition, there is rotational movement of the game object when the sensed directional input is non-zero and the sensed movement is null. The direction of the rotational movement varies in dependence upon the sensed directional input. For example, when the user 12 is standing still and is also providing a directional input in a particular direction, the footballer character will turn to face in a direction associated with that particular direction.

Table 1 illustrates an embodiment in which there is no movement of the game object when the sensed directional input is null even though the sensed movement is non-zero.

Thus, a user 12 running on the spot and providing no directional input would be associated with the footballer character standing still. In an alternative embodiment, there may be some movement of the game object when the sensed directional input is null even though the sensed movement is non-zero. For example, a user 12 running on the spot and providing no directional input might be associated with the footballer character also running on the spot.

Therefore, according to the present invention, in order to move the game object through the game environment, the user 12 must themselves make gross movements of their own body (such as running or walking on the spot). In this way, the user 12 exercises whilst playing the game. Furthermore, the gaming experience is more real since the game object's movements are more closely related to the user's movements.

Table 2 shows an alternative preferred embodiment, in which the directional input comprises a rotational directional input and a translational directional input. In this embodiment, a dual direction sensor (e.g. a gamepad comprising two joysticks) is used to separately control the rotational and translational directions of movement of the game object. For example, the game might be a shooting game in which the game object is a shooter character who moves through the game environment with the ability to face in a different direction (rotational direction) to the direction in which he is moving (translational direction). Such games are generally controlled using gamnepads: one gamepad joystick (usually the left) is used to control a translational direction of movement of the character through the game environment, and the other gamepad joystick is used to control a rotational direction of movement of the character (e.g. a direction in which the character is facing/looking/shooting).

Table 2

In Table 2, regardless of the sensed movement, there is no movement of the game object (translational or rotational) when the sensed directional input is null, as in Table 1.

Similarly, there is no movement of the game object when the translational directional input is non-zero, the rotational directional input is null, and the sensed movement is null.

There is rotational movement of the game object in Table 2 whenever there is a sensed rotational directional input. The direction of the rotational movement varies in dependence upon the sensed rotational directional input.

The rotational movement of the game object may or may not be in combination with translational movement of the game object depending on the sensed translational directional input and the sensed movement.

There is translational movement of the game object in Table 2 when the sensed translational directional input is non-zero and the sensed movement is non-zero. The direction of the translational movement varies in dependence upon the sensed translational directional input.

A speed of movement of the game object may also be controlled by a system according to the present invention (e.g. the system described in Table 1 or Table 2).

In one embodiment, the output signal of the processor 18 is provided such that a speed of movement of the game object varies in dependence upon a magnitude of the sensed directional input. For example, consider a direction sensor 14 comprising a standard analogue joystick. As well as sensing the particular direction in which the joystick is moved, the system could also sense how far the joystick is moved in that particular direction. Thus, assuming that the sensed movement is non-zero (i.e. the player is walking on the spot), if the joystick were only moved a small distance in a particular direction, the game character might walk slowly in the game environment, whereas if the joystick were moved to its full extent in a particular direction, the game character might instead run in the game environment.

In an alternative embodiment, the output signal of the processor 18 is provided such that a speed of movement of the game object varies in dependence upon a speed of the sensed movement. For example, assuming that the sensed directional input is non-zero, a user 12 walking on the spot might walk in the game environment, whereas a user 12 running on the spot might run in the game environment.

In a preferred embodiment, the movement sensor 16 is arranged to sense discrete movement events. An example of such a movement sensor is a pedometer. The pedometer is worn by the user 12 to sense steps taken by the user 12 (i.e. in this embodiment, the discrete events are steps taken by the user 12) The output signal of the processor 18 is provided such that there is translational movement of the game object when -10 -both the sensed directional input is non-zero and a discrete movement event has been sensed by the movement sensor within a predetermined time period. The direction of the translational movement varies in dependence upon the sensed directional input.

Therefore, let us consider the pedometer embodiment with the predetermined time period T set at 1 second. In this case, assuming that the directional input is non-zero, a user 12 stepping at a rate of 1 step per second or more will be associated with the game character walking continuously in the game environment. If the userts step rate drops below 1 step per second, the game character would walk in the game environment in a non-continuous, jerky manner. If the user 12 stopped stepping completely, the game character would stop walking. Preferably, the time T is configurable to give different degrees of exercise for the user 12.

Thus, in this embodiment, the movement sensor 16 may sense discrete movement events of the user 12 in order to simulate continuous movement of the game character.

It will be appreciated that a pedometer could provide a unique common bond between everyday exercise and video game based exercise. For example, a pedometer is typically utilised to enable users to monitor the number of steps taken per day, with the aim of the user reaching a target number of steps as part of their daily exercise routine. If a user only partially reached their daily steps target by wearing the pedometer as usual during the course of the day, the user could then play a video game using the system of the present invention until they attained the target ni.imber of steps.

-11 -As described above, the movement sensor 16 may comprises a pedometer. Alternatively, the movement sensor 16 may comprise at least one pressure pad arranged to sense impacts on the at least one pressure pad by the user 12.

The at least one pressure pad may comprise a dancemat. A movement sensor 16 comprising at least one pressure pad is another example of a discrete movement event sensor.

In a further alternative embodiment, the movement sensor 16 may comprise a camera. In this embodiment, the camera is intended to be directed towards the user so as to view gross movement of the user.

In a preferred embodiment, the system may further comprise an action controlling means having an on state and an off state. The action controlling means is preferably integral with the direction sensor 14. The action controlling means comprises an action sensor arranged to sense the state of the action controlling means.

Furthermore, the movement sensor 16 is arranged to sense a plurality of predetermined movement events. The output signal is then provided such that the game object performs a predetermined action when the action sensor senses that the action controlling means is in the on state. The predetermined action corresponds to the predetermined movement events sensed by the movement sensor 16.

Examples of game actions are jumping, shooting, punching, kicking, ducking, becoming invisible, etc. The action controlling means may comprise a button located on the direction sensor 14. When the button is depressed by a user 12, the state of the button is "on" When the button is not depressed by a user 12, the state of the button is "off". Alternatively, the action controlling means may comprise a switch.

-12 -Let us consider an embodiment in which the direction sensor is a standard gamepad having a joystick as the direction sensor 14 and a button as the action controlling means. Furthermore, let the movement sensor 12 be two pressure pads, a left pressure pad 30 for the user's left foot 34 and a right pressure pad 32 for the user's right foot 36 as shown in Figure 2. An example set of predetermined movement events and the corresponding game actions is shown in Table 3.

Movement event Game action (a) Neither pad is activated Jump (b) Both pads are activated Duck (c) Only the left pad 30 is activated Left kick (d) Only the right pad 32 is activated Right kick

Table 3

Referring to Table 3, when the button is depressed, a game action will occur corresponding to the sensed movement event. For example, if a user 12 is standing on the left pad 30 only when the button is depressed, then the game character will perform a left kick in the game environment.

It will be appreciated that many other sets of movement events and corresponding game actions may be envisaged for various embodiments of the movement sensor 16. In a further embodiment, sequential gross user movements could define a movement event. For example a movement event could be defined by a first activation of the left pad 30, fol1oed by a second activation of the left pad 30, followed by an activation of the right pad 32. Such a sequence would be associated with a game-specific action.

-13 -Although preferred embodiments of the invention have been described, it is to be understood that these are by way of example only and that various modifications may be contemplated.
