TECHNICAL FIELD
The present invention relates to a hand-held video game controller.
BACKGROUND
Hand-held controllers are commonly used to provide user input to a video game running on a game processor such as an IBM PCTM, Sony PlaystationTM or Microsoft XboxTM.
Such controllers commonly include a pair of directional controllers, each operated by a respective thumb. In a conventional XboxTM gamepad, the left thumb can either operate a directional pad (conventionally known as a D-pad) at a front-center position, or an analog stick at a rear-left position. The opposite configuration is commonly used in a conventional PlaystationTM gamepad. That is, the analog stick is at the front-center position, and the D-pad is at the rear-left position.
SUMMARY
The present invention provides a video game controller comprising: a hand-held base unit comprising one or more base unit actuators, each configured to generate a respective actuation signal in response to user input; and a module comprising two or more module actuators, each configured to generate a respective actuation signal in response to user input; wherein the module is mounted to the base unit and can be rotated between two or more orientations to adjust the configuration of the module actuators relative to the base unit actuator(s), and wherein all of the module actuators are accessible to a user in each orientation of the module.
A further aspect of the invention provides a video game controller comprising: a hand-held base unit comprising one or more base unit actuators, each configured to generate a respective actuation signal in response to user input; and a module comprising two or more module actuators, each configured to generate a respective actuation signal in response to user input; wherein the module is mounted to the base unit and can be rotated horizontally between two or more orientations to adjust the configuration of the module actuators relative to the base unit actuator(s).
A further aspect of the invention provides a method of operating a video game controller, the controller comprising a hand-held base unit comprising one or more base unit actuators, each configured to generate a respective actuation signal in response to user input; and a module comprising two or more module actuators, each configured to generate a respective actuation signal in response to user input, the method comprising: mounting the module on the base unit in a first orientation; generating actuation signals with at least one of the base unit actuators and at least two of the module actuators with the module in the first orientation; rotating the module into a second orientation; and generating actuation signals with at least one of the base unit actuators and at least two of the module actuators with the module in the second orientation.
The invention enables the module actuators to be adjusted into a configuration which suits a particular user.
Typically the module or the base unit comprises two or more connectors, each of which forms a first half of a signal interface between the module and the base unit when the module is in a particular orientation. The signal interface may be a contact-less interface in which the signals are transmitted over an air interface—but more preferably the connectors comprise electrical plugs or sockets.
In the preferred embodiment described below, the multiple connectors are on the base unit. This arrangement is preferred since it enables the orientation of the module to be easily sensed by determining the presence of a signal at one or other of the connectors. However it will be appreciated that the arrangement may be reversed: that is with the multiple connectors on the module instead of the base unit.
In the preferred embodiment described below the base unit actuators are carried by the base unit in a fixed position. However, the invention also extends to cover a video game controller in which the base unit actuators are not fixed to the base unit. For instance the base unit actuators may be carried by a second module which is mounted to the base unit and can be rotated between two or more orientations to adjust the configuration of the base unit actuators relative to the base unit.

DETAILED DESCRIPTION
A gamepad 1 shown in FIG. 1 comprises a base unit 2 and a module 3 mounted to the base unit. The base unit carries an analog stick 4 and a set of four action buttons 5. The module 3 carries an analog stick 6 and a directional pad 7 (conventionally known as a D-pad).
The gamepad 1 provides user input to a video game running on a game processor (not shown). The game processor may comprise a dedicated video game console such as a Sony PlaystationTM or Microsoft XboxTM, or a more generic computing device such as an IBM PCTM or laptop.
The analog sticks 4, 6 and D-pad 7 act as direction controllers: that is, actuation signals generated in response to user input by the analog sticks 4, 6 and D-pad 7 are generally used to control direction in the video game, such as the direction of movement of a person in a first-person shooting game. The actuation signals generated in response to user input by the action buttons 5 generally prompt an action in the video game, such as the firing of a shot in a first-person shooting game.
The base unit 2 has a pair of hand grips 8 extending from its front, and a wire (also not shown) connecting the gamepad to the game processor extends from the rear of the base unit.
The analog stick 6 and D-pad 7 are arranged in the orientation shown in FIG. 1; that is, with the D-pad 7 at the front-center position, and the analog stick 6 at the rear-left position. In this orientation the D-pad 7 is symmetrically opposite the analog stick 4, enabling the D-pad 7 to be operated by the left thumb and the analog stick 4 to be operated by the right thumb. This configuration is commonly used in a conventional XboxTM gamepad.
The module 3 can be rotated between the orientation shown in FIG. 1 to the orientation shown in FIG. 2, in which the analog stick 6 is at the front-center position. This configuration is commonly used in a conventional PlaystationTM gamepad. Note that both the analog stick 6 and D-pad 7 are accessible to a user, whether the module is in the FIG. 1 orientation or the FIG. 2 orientation. The rotation of the module is in the same plane as the base unit—i.e. horizontal if the base unit is being held horizontally.
The module 3 is housed in a recess 10 in the upper face of the base unit, shown in FIGS. 3, 6 and 7. Two pairs of spring loaded latches 12 are provided at the base of the recess. The latches 12 engage with recesses 20 on each side of the module 3, shown in FIGS. 4 and 5. A button 13 can be pressed to disengage the latches 12 and eject the module from the recess as shown in FIG. 3.
The base of the module, shown in FIG. 4, has a pair of recesses 21, 22 which are offset from the center of the module by an equal distance D. Therefore the distance between the centers of the recesses 21, 22 is 2D as illustrated in FIG. 4. A set of eight electrical pins 23 projects from the base of the recess 21. This set of pins 23 carries actuation signals from both the analog stick 6 and the D-pad 7. The base of the recess 10 in the base unit has two plugs 14, 15 shown in FIG. 7, each carrying a set of eight electrical sockets, which are each offset from the center of the recess by the distance D. The plugs 14, 15 slide into the module recesses 21, 22 when the module is fitted to the base unit.
Each plug 14, 15 forms a first half of a signal interface which couples the module to the base unit when the module is in a particular orientation. That is, when the module 3 is in the orientation of FIG. 1 the pins 23 are inserted into the sockets carried by the plug 14, and when the module 3 is in the orientation of FIG. 2 the pins 23 are inserted into the sockets carried by the other plug 15.
The plugs 14, 15 each have respective output lines (not shown) which lead to a processor (not shown) in the base unit. The processor senses the orientation of the module by determining the presence of a signal on one or other of the output lines. The processor also acts as an interface between the video game and the various actuators on the game pad. An indication light 16 is illuminated a first colour when the module 3 is in the configuration of FIG. 1, and a second colour when the module 3 is in the configuration of FIG. 2.
Although the invention has been described above with reference to one or more preferred embodiments, it will be appreciated that various changes or modifications may be made without departing from the scope of the invention as defined in the appended claims.
