There are a number of different toys available that can move on their own. Some of these are controlled by the user (e.g. remote control toys) and others are not controlled except for by being started (e.g. switched on or wound up) and stopped (e.g. switched off) by the user. Examples of the latter type include motorized toy trains which run on a track when switched on until they are switched off or run out of power and toy vehicles which a user pulls back and then lets go and the vehicle moves forward until the spring mechanism (which was wound by the pulling back of the vehicle) has unwound.
The embodiments described below are not limited to implementations which solve any or all of the disadvantages of known toys.
The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements or delineate the scope of the specification. Its sole purpose is to present a selection of concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later.
Methods and systems for controlling physical toys using a physics engine are described. In an embodiment, a physics engine within an interactive software experience is used to model the motion of a virtual object in a virtual environment. The output of this modelling is then imposed on a physical toy which corresponds to the virtual object such that the motion of the physical toy in the real world more closely matches the motion of the virtual object in the virtual environment. In various examples, the modelling is imposed through control signals which are generated based on output of the physics engine and used to control actuators within the physical toy to change the motion of at least a part of the toy.
Many of the attendant features will be more readily appreciated as the same becomes better understood by reference to the following detailed description considered in connection with the accompanying drawings.
The present description will be better understood from the following detailed description read in light of the accompanying drawings, wherein:
Like reference numerals are used to designate like parts in the accompanying drawings.
The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples.
As described above, there are a number of different toys available that can move on their own. These toys are physical, real-world toys which a user can touch and pick-up. These are distinct from virtual objects which exist in a virtual world (e.g. in a computer game). A user can interact with a virtual object (e.g. using a keyboard, mouse, touch screen or games controller) but cannot touch or pick-up a virtual object. A virtual object has no mass, unlike a real-world object.
A number of computer games have been developed in which gameplay is enabled (or unlocked) through the use of physical character toys which are placed on a custom base connected via a USB lead to a games console. By placing different toys on the custom base, different gameplay is enabled. Such games, however, do not encourage user interaction with the toys (other than to place them on the custom base) and the toys are instead used as a physical replacement for configuring particular parameters of the computer game.
A play system is described below in which the motion of all or a part of a physical real-world toy is changed to reflect motion of a corresponding virtual toy (i.e. a virtual object in a virtual world). This system closely links play in the real world with play in the virtual world and encourages user interaction with the real-world toy as well as with the virtual world. A user may prefer to interact with the virtual toy through interaction with the real-world toy for various reasons including the more natural or playful interaction, the more realistic 3D and tactile nature of real world toys compared to virtual toys presented on a computing input/output device, the fidelity, accuracy and simplicity of control using real-world movements compared to learning and manipulating virtual controls, etc. On other occasions (or in other situations) the user may prefer to interact through the virtual controls, e.g. for access to menus, configuration or control mechanisms that are not present on the real-world toy. The virtual world enhances the physical play experienced by a user through its control of the motion of the real-world toy and also through presentation of the virtual world to the user which may provide images of an environment, sound effects, other objects with which the real-world toy (and its corresponding virtual object) can interact, etc.
In an example, the real-world toy is a toy car and the virtual object that corresponds to the toy car is a virtual car in a virtual world provided by an interactive software experience (which may be a computer game). The virtual world may provide one or more different environments in which the car (i.e. the virtual car and its real-world counterpart) can be driven, e.g. an arctic environment and a desert environment. The user selects an environment (e.g. the arctic environment in which the road surface is covered in snow and ice) and the virtual world shows the environment in its graphical user interface (GUI) and may show the virtual object (i.e. the virtual car) on the snowy road surface. When the user moves the real-world car, a physics engine within the interactive software experience provides control signals to the real-world car. These control signals change the motion of at least a part of the real-world car (e.g. one or more wheels) such that, to the user, the real-world car feels like it is driving on the snowy road surface depicted in the GUI and not the real-world surface on which the car is being moved (e.g. the carpet, a table top, etc.). This enhances the user experience through providing a realistic real-world motion which corresponds to the virtual world that is being displayed to the user.
As is known in the art, a physics engine simulates (or models) physical phenomena. In various examples a physics engine provides approximate simulation of one or more physical systems (e.g. gravity, collision detection, rigid body dynamics, soft body dynamics, rotation calculations, fluid dynamics, friction force modelling, etc.) in one or more dimensions (e.g. in 3D). The simulation may be intended to model real-world physics as closely as possible, or may deliberately differ from real-world physics in some ways, e.g. changing the gravitational constant, the speed of light, etc. or deliberately ignoring some physical constraints while following others, e.g. permitting the user to rotate at any desired speed without applying constraints related to the moment of inertia of rotation and the physical force required to achieve such rotation. The simulation may also deliberately depart from real-world physics in particular game situations, e.g. to assist players in certain situations by altering or violating physical models to make the game easier (e.g. permitting a virtual car to maintain traction and/or correct orientation around a corner despite the model determining that a skid and/or spin should happen). The simulation is performed in real-time and in many examples the physics engine is implemented in software. In various examples, a dedicated processor or dedicated subset of a multiprocessor (a physics processing unit, PPU) may be used to perform the calculations required by the physics engine.
In various examples, the toy 102 may also comprise one or more sensors 116 which are arranged to detect motion of the toy (i.e. real-world motion) and communicate this to the interactive software experience 106 via the communication interface 104 (which may further comprise a transmitter, which in many examples will be a wireless receiver). In such examples, the interactive software experience 106 receives the sensor data (from sensor 116) via communication interface 113 and the sensor data received is used by the physics engine 107 when simulating the motion of the virtual object which corresponds to the real-world toy 102 in real-time. For example, the sensed motion of the real-world toy 102 may be applied to the virtual object which corresponds to the real-world toy 102 (e.g. such that if a user makes a real-world toy car turn right, the virtual world object mimics this motion and also turns right). It will be appreciated that compensating factors such as scaling factors may be used when applying the motion to the virtual object in the physics engine 107 (e.g. a virtual car may be modelled by the physics engine as if it was a similar mass to a real-world car and not the real-world toy car to which the virtual car corresponds). As described above, the simulation may be intended to model real-world physics as closely as possible, or may deliberately differ from real-world physics in some ways and/or in some game situations.
In various examples, one or more sensors 116 may in addition, or instead, be used to detect the real-world surroundings of the toy 102 and this information may be communicated to the interactive software experience (via communication interfaces 104, 113) and fed into the simulation performed by the physics engine 107. For example, a sensor 116 may detect obstacles in the real-world (e.g. walls, furniture, etc.) and data about these obstacles may be passed to the interactive software experience 106 and used in the modelling performed by the physics engine 107, e.g. such that the toy 102 reacts more realistically if it crashes into a piece of furniture or a wall. The detected surroundings (obstacles) may also be displayed visually to the user within the virtual world by the interactive software experience (e.g. obstacles may be represented as walls, rocks, etc.).
The computing device 108 which may be a desktop, laptop or tablet computer, a games console, a smart phone or any other computing device and in various examples computing device 108 may be a handheld computing device. In other examples, however, the computing device 108 may be integrated into the physical toy as shown in
Although
Although
Like in the first example, the toy 202 in the second example 200 comprises a controlling mechanism 105 which controls the motion (e.g. actual motion or range of possible motion) of at least a part of the toy (e.g. one or more of the wheels 103) based on control signals generated by the physics engine 107 within the interactive software experience 106. As described above, the physics engine 107 simulates the motion of the virtual object which corresponds to the real-world toy 102 in a virtual environment provided by the interactive software experience 106 and generates the control signals based on the simulation. As described above, in various examples the toy 202 may comprise one or more sensors 116 which may be used to detect motion of the toy 202 and/or the surroundings of the toy 202.
In any of the examples described above, the translation between the simulation (performed by the physics engine 107) and the required change in the motion of at least a part of the real-world toy 102, 202 may be performed by the physics engine 107 (either in a separate stage or as an integrated part of the physics simulation that is optimized to compute both the virtual physics and real-world control in a single computational task), the interactive software experience 106 or by the controlling mechanism 105 or by a combination of two or more of these elements. As described above, some or all of the computation associated with the interactive software experience (and the physics engine) may be performed on a remote computing-device which provides input to the computing device 108.
The operation of the play systems 100, 200 shown in
It will be appreciated that the motion may be changed in many ways (in block 305) and in various examples it may be augmented (e.g. subsequent motion of the toy be a user may be enhanced by the controlling mechanism in some way), constrained (e.g. a range of possible motion may be limited) or otherwise affected. In various examples, the control signals (generated in block 304) may attempt to replicate virtual-world motion (of the virtual object) in the real world (with the real-world toy that corresponds to the virtual object). Exact replication may not be possible and so in various examples, the control signals (generated in block 304) may attempt to minimize any difference between real-world motion of the real-world toy and virtual-world motion of the virtual object which corresponds to the real-world toy. In other examples, however, the control signals (generated in block 304) may not result in replication of the virtual-world motion but may change the real-world motion in a similar, but not identical manner and this may be a consequence of a limitation in the operation of actuators or other elements within the controlling mechanism 105. For example, although in the virtual world the virtual object (e.g. a virtual car) may roll over, the control signals may cause the real-world toy (e.g. a toy car) to move sideways or stop but not to roll over.
In examples where the interactive software experience 106 is not run within the real-world toy (e.g. as shown in
In various examples, a real-world toy 102, 202 comprises one or more sensors 116 which may detect the motion of the real-world toy (block 312) and/or the real-world toy's surroundings (block 314). In such examples, the sensor data is received by the interactive software experience 106 (block 316) and used in the modelling (in block 302) and/or in generating the GUI (in block 306).
In the first example 401, the real-world toy 410 is a toy car. When a user moves the car backwards (as indicated by arrow 412), this motion is sensed by the car (and/or by sensors in the computing device) and input to the physics engine. The physics engine models the resultant motion of the corresponding virtual object and provides control signals to the toy car 410 which, when implemented by the controlling mechanism 105, cause the toy car 410 to move forwards (as indicated by arrow 414). In this way, the toy car 410 operates (as far as the user experience is concerned) as if it has a spring mechanism inside it; however it does not and the effect is generated by the physics engine. By generating the car's response in this way, rather than having a mechanical mechanism that reacts to the user pulling the car back, the resultant motion of the car can be modified in many different ways based on characteristics in the virtual world (e.g. to reflect whether the car is being driven on a road/field/beach, to reflect different engine sizes, etc.).
In the second example 402, the real-world toy 420 is a figurine and is shown at two different points in time 421-422. This toy 420 may, for example, be a knight engaged in a battle or a worker who is chopping wood. When a user lifts the arm of the figuring 420 (as indicated by arrow 424 in the first scene 421), this motion is sensed by the figurine (and/or by sensors in the computing device) and input to the physics engine. The physics engine models the resultant motion of the arm of the corresponding virtual object (e.g. the virtual knight or worker) and provides control signals to the figurine 420 which, when implemented by the controlling mechanism 105, cause the arm to move forwards and down (as indicated by arrow 426 in the second scene 422), e.g. as if the figurine is throwing a punch or chopping a log. As with the first example, by generating the motion of the arm in this way, rather than having a mechanical mechanism that reacts to the user lifting up the figurine's arm, the resultant motion of the arm can be modified in many different ways based on characteristics in the virtual world (e.g. based on what the figurine is doing in the virtual world).
In the third example 403, the real-world toy 430 is again a toy car. When a user moves the car forwards (as indicated by arrow 432), this motion may be sensed by the car (and/or by sensors in the computing device) and input to the physics engine, although in other examples sensing is not required and the motion of the car forwards in the virtual world may not rely on sensing motion of the real-world toy 430. In the virtual world there is an oil slick 434 and the physics engine models the resultant motion of the corresponding virtual object when it drives into the oil slick 434. The interactive software experience then provides control signals to the toy car 430 which, when implemented by the controlling mechanism 105, cause the toy car 430 to swerve or otherwise be difficult to drive in straight line in the real-world (as indicated by arrow 436). In this way, the real-world toy car 430 operates (as far as the user experience is concerned) as if it has driven into an oil slick which only exists in the virtual world (depicted by the interactive software experience). By using the physics engine in this way, the motion of the real-world car can be modified dynamically to correspond to changes in the virtual environment (e.g. driving onto ice, into water, onto sand, etc.) and provide an enhanced user experience (e.g. a more immersive experience) with the physical toy.
In the fourth example 404, the real-world toy 440 is also a toy car and the car 440 is shown at two different points in time 441-442. In this example, a user may move the car and this may be sensed by the car (and/or by sensors in the computing device) and communicated to the physics engine, sensing alternatively may be omitted. In the first scene 441 all the tires are intact; however, in the second scene 442 the motion of the car 440 is modified (as indicated by lines 446 representing vibrations/juddering of the car) as if one of the tires has burst 444. The motion which results from the burst tire is modelled by the physics engine and the interactive software experience then provides control signals to the toy car 440 which, when implemented by the controlling mechanism 105, causes the juddering/vibrations 446. This is another example of how, by using the physics engine in this way, the motion of the real-world car can be modified dynamically to correspond to changes in the virtual environment (e.g. changes in the state of the virtual object) and provide an enhanced user experience (e.g. a more immersive experience) with the physical toy.
In the fifth example 405, the real-world toy 450 is a figurine and the corresponding virtual object 452 (e.g. a virtual person) is shown in the GUI 454 of the interactive software experience. In the example shown, the virtual person 452 is carrying a heavy weight 456. The physics engine models the effect on the arm of the virtual person of carrying this weight 456 and provides control signals to the figurine 450 which, when implemented by the controlling mechanism 105, prevent the user from lifting up the corresponding arm on the real-world figurine 450 (as indicated by the arrow 458 with a cross through it). This is further example of how, by using the physics engine in this way, the motion of a real-world toy can be modified dynamically to correspond to changes in the virtual environment (e.g. changes in the state of the virtual object) and provide an enhanced user experience (e.g. a more immersive experience) with the physical toy.
In the sixth example 406, the real-world toy 460 is a set of blocks which are used to create a bridge across a gap between two objects 462, 464 which may be other blocks (i.e. other real-world toys) or parts of the surroundings (e.g. furniture which is sensed by the bricks (and/or by sensors in the computing device) and communicated to the interactive software experience). The corresponding virtual object 466 (e.g. a virtual bridge formed from virtual blocks) is shown in the GUI 468 of the interactive software experience. In the example shown, a user can select a vehicle (from vehicles 472) to drive (in the virtual world) across the virtual bridge 466 and in the example shown, the user has selected a small truck 470. The physics engine models the effect on the virtual bridge 466 of the small truck 470 being driven across it and if it determines that the bridge will buckle or collapse, the interactive software experience provides control signals to the real-world blocks 466 which, when implemented by the controlling mechanism 105, cause the real-world bridge to collapse (as indicated by the double arrow). This is yet further example of how, by using the physics engine in this way, the motion of a real-world toy can be modified dynamically to correspond to changes in the virtual object and provide an enhanced user experience (e.g. a more immersive experience) with the physical toy.
In various examples, a real-world toy in the examples described above may themselves be modular and be formed from two or more modules.
The processor 610 and actuator(s) 609 within the core module 602 act as the controlling mechanism 105 described above and change the motion of the real-world toy based on control signals generated by the interactive software experience 106. Examples of suitable actuators include motors, vibration units, servos, muscle wire, solenoids, electromagnetic actuators (e.g. if the environment is metallic), pneumatic or hydraulic actuators, etc. The processor 610 may be a microprocessor, controller or any other suitable type of processor for processing computer executable instructions to control the operation of the core module in order to change the motion of at least a part of the real-world toy and this may involve changing the motion of the core module relative to a connected peripheral module.
In various examples, the processor may also collect the IDs (which may be a unique ID or an ID shared with other identical-looking modules, e.g. an ID for a particular shape or type of module) of each of the modules connected together to form a coherent physical whole object which forms the real-world toy. The module IDs may be collected from each of the connected modules directly (e.g. via a bus) or each module may collect information on its neighbors with the core module aggregating the data provided by its direct neighbor play pieces. In various examples, these module IDs may be collected via the data connection provided by the connectors 612 and in other examples, another means may be used (e.g. NFC, QR codes or computer vision). Where other means are used, the core module 602 may comprise additional hardware/software such as an NFC reader module or a camera or other image sensor to collect the module IDs of all the connected play pieces. In addition to collecting the module IDs of the connected module (e.g. to generate a set or list of connected modules), the core module may detect the topology of the arrangement of play pieces.
Each peripheral module 604 comprises one or more connectors 612, 614 to physically attach the module to another module to form a coherent physical whole object which forms the real-world toy. The peripheral module 604 may also comprise one or more actuators 609 for moving the peripheral module. The peripheral module 604 may further comprises electrical connections 624 (e.g. in the form of a bus comprising 2 wires, data and ground) between the two connectors 612, 614. In the example shown in

It will be appreciated that the modules 602, 604 shown in
Computing-based device 700 comprises one or more processors 702 which may be microprocessors, controllers or any other suitable type of processors for processing computer executable instructions to control the operation of the device in order to perform the methods described herein (e.g. to model the virtual object in the virtual environment and generate control signals to change the motion of a real-world toy corresponding to the virtual object). In various examples, one of the processors 702 may be a PPU and may be used by the physics engine. In some examples, for example where a system on a chip architecture is used, the processors 700 may include one or more fixed function blocks (also referred to as accelerators) which implement a part of the method of generating and presenting an interactive story in hardware (rather than software or firmware).
Alternatively, or in addition, the functionality described herein can be performed, at least in part, by one or more hardware logic components. For example, and without limitation, illustrative types of hardware logic components that can be used include Field-programmable Gate Arrays (FPGAs), Program-specific Integrated Circuits (ASICs), Program-specific Standard Products (ASSPs), System-on-a-chip systems (SOCs), Complex Programmable Logic Devices (CPLDs).
Platform software comprising an operating system 704 or any other suitable platform software may be provided at the computing-based device to enable application software, such as an interactive software experience 106 to be executed on the device. As shown in
The computer executable instructions may be provided using any computer-readable media that is accessible by computing based device 700. Computer-readable media may include, for example, computer storage media such as memory 712 and communications media. Computer storage media, such as memory 712, includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EPROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information for access by a computing device. In contrast, communication media may embody computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave, or other transport mechanism. As defined herein, computer storage media does not include communication media. Therefore, a computer storage medium should not be interpreted to be a propagating signal per se. Propagated signals may be present in a computer storage media, but propagated signals per se are not examples of computer storage media. Although the computer storage media (memory 712) is shown within the computing-based device 700 it will be appreciated that the storage may be distributed or located remotely and accessed via a network or other communication link (e.g. using communication interface 714).
The communication interface 714 may be arranged to transmit control signals to the real-world toy and may comprise a wireless transmitter. In various examples, the communication interface 714 may also be arranged to receive sensor data from the real-world toy and may comprise a wireless receiver. In such examples the communication interface 714 may receive data from the real-world toy directly or via an intermediary device.
In examples where the computing-based device 700 is integrated within a real-world toy (e.g. as shown in
The computing-based device 700 may also comprise an input/output controller 716. The input/output controller may be arranged to output presentation information (or display data) for use in presenting the virtual world to the user to a presentation device 718 (e.g. a display device) which may be separate from or integral to the computing-based device 700. The input/output controller 716 may also be arranged to receive and process input from one or more devices, such as a user input device 724 (e.g. a mouse, keyboard, camera, microphone or other sensor). In some examples the user input device 724 may detect voice input, user gestures or other user actions and may provide a natural user interface (NUI). This user input may be used to further control the interactive story. In an embodiment the presentation device 718 may also act as the user input device 724 if it is a touch sensitive display device. The input/output controller 716 may also output data to devices other than the display device, e.g. a locally connected printing device (not shown in
Any of the input/output controller 716, presentation device 718 and the user input device 724 may comprise NUI technology which enables a user to interact with the computing-based device in a natural manner, free from artificial constraints imposed by input devices such as mice, keyboards, remote controls and the like. Examples of NUI technology that may be provided include but are not limited to those relying on voice and/or speech recognition, touch and/or stylus recognition (touch sensitive displays), gesture recognition both on screen and adjacent to the screen, air gestures, head and eye tracking, voice and speech, vision, touch, gestures, and machine intelligence. Other examples of NUI technology that may be used include intention and goal understanding systems, motion gesture detection systems using depth cameras (such as stereoscopic camera systems, infrared camera systems, RGB camera systems and combinations of these), motion gesture detection using accelerometers/gyroscopes, facial recognition, 3D displays, head, eye and gaze tracking, immersive augmented reality and virtual reality systems and technologies for sensing brain activity using electric field sensing electrodes (EEG and related methods).
Although the present examples are described and illustrated herein as being implemented in a play system (comprising a real-world toy and an associated interactive software experience) as shown in
An aspect provides a toy comprising an input for receiving control signals generated by an interactive software experience. The control signals are generated based on modelling performed by a physics engine of a virtual object in a virtual environment and the virtual object corresponds to the toy or a proximate toy. The toy also comprises a controlling mechanism operative to change a motion of at least a part of the toy (e.g. a wheel, a limb, etc.) corresponding to the virtual object in response to receiving a control signal. In an example, the virtual object corresponds to the toy itself and the controlling mechanism changes the motion of at least a part of the toy itself. In another example, the virtual object corresponds to a proximate toy (i.e. a second toy which is close to the toy itself) and the controlling mechanism changes the motion of at least a part of that proximate toy.
This makes the real-world motion of the real-world toy more closely match (e.g. in terms of look and/or feel to a user) the virtual world motion within the interactive software experience. This enhances the user experience and provides a more immersive experience (i.e. the user feels more like the physical toy is part of the virtual world).
In various examples, the controlling mechanism is operative to change the motion of at least a part of the toy corresponding to the virtual object to reduce a difference between modelled motion of the virtual object in the virtual environment and real-world motion of the toy corresponding to the virtual object. For example, the controlling mechanism may be operative to change the motion of at least a part of the toy to mimic (in the real world) the modelled motion of the virtual object in the virtual environment.
In various examples, the controlling mechanism comprises one or more actuators, wherein the actuators are controllable by the control signals. These actuators change the motion of the real-world toy.
In various examples, the input comprises a communication interface arranged to receive signals from a computing device running (or capable of running) the interactive software experience.
In various examples, the toy further comprises one or more sensors arranged to detect an aspect of the surroundings of the toy corresponding to the virtual object and/or to detect motion of the toy corresponding to the virtual object. This further enhances the user experience and provides a more immersive experience (i.e. the user feels more like the physical toy is part of the virtual world). By sensing the motion, the physics engine can generate complementary or reactive motion within the real-world toy (e.g. it can generate a reaction within the toy to an initial action by a user, as described above with reference to examples 401, 402, 405).
In various examples, where the toy corresponds to the virtual object, the toy further comprises the physics engine.
In various examples, where the toy corresponds to the virtual object, the toy further comprises a processor and a memory. The memory comprises the physics engine (which comprises device-executable instructions which when executed cause the processor to model motion of the virtual object in the virtual environment) and device-executable instructions which when executed cause the processor to: generate the control signals based on the modelling; and generate graphical user interface data, the graphical user interface showing the virtual object in the virtual environment.
In various examples, the toy further comprises a communication interface arranged to transmit the graphical user interface data to a computing device comprising a presentation device for displaying the graphical user interface.
Another aspect provides a method comprising: modelling, in a physics engine, motion of a virtual object in a virtual environment; and generating control signals to impose output from the physics engine on a physical toy by changing a motion of at least a part of a physical toy, wherein the virtual object corresponds to the physical toy. The method may further comprise generating graphical user interface data, the graphical user interface showing the virtual object in the virtual environment.
In various examples, the control signals are generated to change the motion of at least a part of the toy to reduce a difference between modelled motion of the virtual object in the virtual environment and real-world motion of the toy.
In various examples the method further comprises: transmitting, via a communication interface, the control signals to the physical toy.
In various examples the method further comprises: displaying the graphical user interface on a presentation device.
In various examples the method further comprises: transmitting, via a communication interface, the graphical user interface data to a presentation device.
In various examples the method further comprises: receiving sensor data, the sensor data identifying motion of the toy and/or an aspect of the toy's surroundings; and using the sensor data when modelling, in a physics engine, motion of the virtual object in the virtual environment.
In various examples, the sensor data is received from the toy via a communication interface.
Another aspect provides a computing-based device comprising: a processor and a memory. The memory comprises device-executable instructions which when executed cause the processor to: model motion of a virtual object in a virtual environment; and generate the control signals based on the modelling, the control signals being operative to change a motion of at least a part of a physical toy which corresponds to the virtual toy. The device-executable instructions may, when executed, further cause the processor to generate graphical user interface data, the graphical user interface showing the virtual object in the virtual environment.
In various examples, the control signals are operative to reduce a difference between modelled motion of the virtual object in the virtual environment and real-world motion of the toy.
In various examples, the computing-based device further comprises a communication interface arranged to transmit the control signals to the physical toy or to a proximate toy. In this way, the control of the motion may be implemented within the toy that is being modelled or a toy which is close to the one that is being modelled by the physics engine (e.g. where the control is performed by tracks, a baseboard, etc.).
In various examples, the communication interface is further arranged to receive sensor data from the physical toy, the sensor data providing information on motion of the physical toy and/or surroundings of the physical toy and wherein the sensor data is used to model the motion of the virtual object in the virtual environment.
Another aspect provides a toy comprising a means for receiving control signals generated by an interactive software experience. The control signals are generated based on modelling performed by a physics engine of a virtual object in a virtual environment and the virtual object corresponds to the toy. The toy also comprises means for changing a motion of at least a part of the toy (e.g. a wheel, a limb, etc.) in response to receiving a control signal.
A yet further aspect provides a computing-based device comprising means for modelling motion of a virtual object in a virtual environment and means for generating the control signals based on the modelling, the control signals being operative to change a motion of at least a part of a physical toy which corresponds to the virtual toy. The computing-based device may further comprise means for generating graphical user interface data, the graphical user interface showing the virtual object in the virtual environment.
The term ‘computer’ or ‘computing-based device’ is used herein to refer to any device with processing capability such that it can execute instructions. Those skilled in the art will realize that such processing capabilities are incorporated into many different devices and therefore the terms ‘computer’ and ‘computing-based device’ each include PCs, servers, mobile telephones (including smart phones), tablet computers, set-top boxes, media players, games consoles, personal digital assistants and many other devices.
The methods described herein may be performed by software in machine readable form on a tangible storage medium e.g. in the form of a computer program comprising computer program code means adapted to perform all the steps of any of the methods described herein when the program is run on a computer and where the computer program may be embodied on a computer readable medium. Examples of tangible storage media include computer storage devices comprising computer-readable media such as disks, thumb drives, memory etc. and do not include propagated signals. Propagated signals may be present in a tangible storage media, but propagated signals per se are not examples of tangible storage media. The software can be suitable for execution on a parallel processor or a serial processor such that the method steps may be carried out in any suitable order, or simultaneously.
This acknowledges that software can be a valuable, separately tradable commodity. It is intended to encompass software, which runs on or controls “dumb” or standard hardware, to carry out the desired functions. It is also intended to encompass software which “describes” or defines the configuration of hardware, such as HDL (hardware description language) software, as is used for designing silicon chips, or for configuring universal programmable chips, to carry out desired functions.
Those skilled in the art will realize that storage devices utilized to store program instructions can be distributed across a network. For example, a remote computer may store an example of the process described as software. A local or terminal computer may access the remote computer and download a part or all of the software to run the program. Alternatively, the local computer may download pieces of the software as needed, or execute some software instructions at the local terminal and some at the remote computer (or computer network). Those skilled in the art will also realize that by utilizing conventional techniques known to those skilled in the art that all, or a portion of the software instructions may be carried out by a dedicated circuit, such as a DSP, programmable logic array, or the like.
Any range or device value given herein may be extended or altered without losing the effect sought, as will be apparent to the skilled person.
