The present disclosure relates generally to the field of interactive children's toys and capacitive touch sensing technologies.
Interactive toys stimulate and entertain children and contribute to childhood development. Electronic capacitive touch sensing technologies provide means for user input to interactive devices. Continuing improvements to products in these fields are sought. It is to the provision of children's toys and other interactive products having new and improved capacitive touch sensor-based user input means that the present disclosure is primarily directed.
In example embodiments, the present disclosure relates to an interactive children's toy or other device, having capacitive touch user input technology. The children's toy or other device generally includes at least one capacitive touch sensor user input, coupled to an integrated circuit or other electronic processing device, and one or more output features or components for delivering entertaining, educational, and/or output or feedback to the user in response to the user input. In example embodiments, the output may be in the form of music, voice or other sound, color or light, electronic data, text display, motor operation, magnetic actuator operation, and/or other output content or format.
In example embodiments, a user input of a device according to the present disclosure comprises a smooth and continuous seamless surface, for example formed of a thin panel of wood overlying one or more capacitive touch sensors, with user-input areas indicated or defined on the surface, for example by painting, stain, or decals applied onto the wood panel. The provision of a smooth and continuous seamless user input surface eliminates or minimizes crevices or recesses where dirt, food residue or other debris might collect, making it easier to clean the device, and preventing interference with internal electronics, switches or other components.
In example embodiments, the capacitive touch user input includes an overlay layer, a sensor layer, and a base or substrate layer. One or more of the overlay layer, sensor layer, and base layer can be manufactured from a flexible substrate, enabling the capacitive touch device to be installed in various arrangements tailored to the shape of the device in which the capacitive touch device is implemented.

The capacitive touch sensors 42, 44, 46, 48 beneath the user input areas 22, 24, 26, 28 sense the change in capacitance resulting from user contact with the wood or other capacitive discharge conductive material, and provide an electronic input signal to the capacitive touch IC 84 indicating a user contact input, which in turn signals the sound output IC 82 to output a sound signal to play a sound on the speaker 92. In example embodiments, user contact with each of the capacitive touch sensors 42, 44, 46, 48 generates a different sound output, for example, a base drum sound output, a snare drum sound output, a tom drum sound output, a cymbal sound output, etc. Optionally, the capacitive touch sensor system 40 senses the force or level of the contact as well as the contact itself, and the electronic input-output control system 80 generates sound outputs of varying volume, pitch or intensity corresponding to the input level. In further embodiments, the electronic input-output control system 80 optionally generates one or more melodies for the user to drum along with, and/or generates example drum beat patterns for the user to follow or play along with, or simply overlay drum or other instrument sounds on top of a playing melody.

For example, and as seen with reference to
The capacitive touch sensor system 140 is mounted between the base 160 and the user interface panel 120, and comprises a plurality of capacitive touch sensors 141, 142, 143, 144, 145, 146, 147, 148, corresponding to and aligned beneath the user input keys 121, 122, 123, 124, 125, 126, 127, 128, respectively.

The user interface panel 220 preferably comprises a relatively thin material thickness in the user input areas 222 for improved capacitive touch sensitivity, and optionally further comprises a relatively thicker material thickness in one or more surrounding or peripheral areas outside of the user input areas for improved durability and structural strength. For example, and as seen with reference to
The capacitive touch sensor system 240 is mounted between the component housing 260 and the user interface panel 220, and comprises a plurality of capacitive touch sensors 242, for example sensors 242C, 242D, 242E, 242F, 242G, 242A, 242B and 242C′, corresponding to and aligned beneath the user input keys 222 of corresponding musical notes on the upper surface of the user interface panel 220, respectively.

In example embodiments, the user interface panel 620 comprises a smooth and continuous seamless exterior user input surface, without significant crevices or recesses in or around the user input areas, where dirt, food residue or other debris might collect. In substantially similar fashion to the above-described embodiments, the user interface panel 620 may comprise a unitary, integral component formed of a capacitive discharge conductive material, such as natural or synthetic wood, fabric, plastic, glass, or other material compatible with electronic capacitive touch sensor systems. In particular example embodiments, the user interface panel comprises a natural organic material such as wood or other plant-based materials. In the depicted example embodiment, the user interface panel 620 comprises a natural wood panel, such as for example a wood veneer panel having a material thickness of between about 1 mm to about 5 mm, more preferably about 2 mm-4 mm, for example about 2.5 mm or about 3 mm thick. One or more openings are optionally provided through the user interface panel 620 aligned with input and/or output components such as an audio speaker and user input controls.
The capacitive touch sensor system 640 comprises one or more capacitive touch sensors 642A, 642B. In example embodiments, the capacitive touch sensors 642A, 642B comprise an electrically conductive material such as, for example a copper or other metallic foil, sheet, strip, panel, button, or other configuration, and are connected by wires or other electrical conductors to the electronic input-output control system 680. In the depicted example embodiment, the capacitive touch sensor system 640 comprises a plastic panel 646, upon which the capacitive touch sensors 642A, 642B and the strings 618 of the ukulele toy are mounted, with a capacitive touch sensor printed circuit board mounted in contact with the underside of the panel 646, and one or more metallic foil or other capacitive touch sensors corresponding to the user input areas 622 of the user interface panel 620.
The electronic input-output control system 680 may also be mounted on the panel 646. In example embodiments, the input-output system 680 comprises one or more integrated circuits (ICs), one or more printed circuit boards, and associated electronic components, in like manner as the above-described embodiments. One or more manual inputs such as switches 670, 672, 674 may be provided in electronic communication with the electronic input-output control system 680, for selective user control of power on/off, volume control, mode switching, melody activation, and/or other features. One or more output features may also be provided in electronic communication with the electronic input-output control system 680, such as an audio speaker 692, lights, vibration transducers, and/or other outputs. The housing 660 optionally further includes a battery compartment 694 for DC batteries to power the toy; and/or an AC power adaptor and electrical cord connection. In example embodiments, one or more springs 619 mounted to the panel 646 keep the strings 618 in tension.
In example modes of use of the ukulele toy 610, capacitive touch sensors under the wood surface detect the child's touch inputs. In a “Guided Play” Mode, the melodies are broken into short fragments (i.e. 1 measure) and sequential inputs to the capacitive touch sensors drive the melody playback fragment-by-fragment, measure-by-measure. Each fragment leads off with a powerful strum and the short duration of the sequences creates the illusion that the infant is playing the Ukulele in a meaningful way. Because any touch will interrupt the playing fragment and immediately play the next fragment in the sequence, the toy remains responsive throughout Guided Play. In a “Free Play” Mode, successive touch inputs sequentially play a defined sequence of strums that make musical sense, thus reducing cacophonous playback. If a melody is already playing, the capacitive touch inputs play a Ukulele chord that aligns with the current key of the playing melody at any given moment, again to reduce cacophony; overlay ukulele sounds are optionally dynamically pitched to match the underlying melody.
The capacitive touch sensor system 740 comprises one or more, and preferably a plurality of capacitive touch sensors 742A-742P, corresponding to and aligned beneath respective user input surfaces 722A-722P. Optionally, an additional capacitive touch sensor 744 is provided, aligned beneath the start button user input area 724. In example embodiments, the capacitive touch sensors 742, 744 comprise an electrically conductive material such as, for example a copper or other metallic foil, sheet, strip, panel, button, or other configuration, and are connected by wires or other electrical conductors to the electronic input-output control system 780. In the depicted example embodiment, the capacitive touch sensor system 740 comprises a printed circuit board 746 incorporating the capacitive touch sensors 742, 744 and associated electronic components and capacitive touch sensor circuitry.
In example embodiments, the base or housing 760 comprises a plastic molding having an internal housing chamber 762 therein. The base 760 optionally further includes one or more manual inputs such as switches 770, 772 in electronic communication with the electronic input-output control system 780, for selective user control of power on/off, volume control, mode switching, language selection, melody activation, and/or other features. The base 760 optionally further includes one or more output features in electronic communication with the electronic input-output control system 780, such as an audio speaker 792, lights, vibration transducers, and/or other outputs. The base 760 optionally further includes a battery compartment 794 for DC batteries to power the toy; and/or an AC power adaptor and electrical cord connection.
The electronic input-output control system 780 is preferably mounted in or on the base or housing 760. In example embodiments, the input-output system 780 comprises one or more integrated circuits (ICs), one or more printed circuit boards, and associated electronic components, in like manner as the above-described embodiments. In example modes of use of the tablet toy 710, a child or other user contacts the user input icons 722 of the user interface panel 720 with their fingers or with a conductive stylus. The capacitive touch sensors 742 beneath the user input keys sense a change in capacitance through the thin portions of the wood user interface panel 720 upon user contact, providing an electronic input signal to the electronic input-output control system 780, which in turn outputs a sound or other output signal to play a voice or other sound on the speaker 792 and/or to activate one or more other output features. In example embodiments, user contact with each of the user input icons 722A-722P generates a different output. In further embodiments, the electronic input-output control system 780 optionally generates one or more queries or instructions to prompt the user to contact a specified user input icon 722, which in turn generates a predetermined response for interactive feedback with the user. For example, the system may prompt a user to touch the icon showing an apple, and upon sensing user input contact with the apple icon may generate a confirmatory response (or may generate a corrective response indicating an incorrect user input contact with a different icon). Alternatively or additionally, a user-directed mode of use may allow the user to contact any icon, and generate a system response identifying that particular icon or a characteristic associated with that icon.
In various example embodiments, and with reference to the general schematic diagram of
The sensor layer 940 includes one or more capacitive touch sensors, which generate a sensor signal based on and responsive to the user input. The sensor signal can optionally include an indication of a location at which the user input was received by the overlay layer. The sensor signal can correspond to a change in capacitance of the sensor layer (or electrical components thereof) resulting from the user input. The sensor layer can generate the sensor signal based on capacitive coupling between the object contacting the overlay layer and the sensor layer. The sensor layer can generate the sensor signal using surface capacitance or projected capacitance. The sensor layer can include a conductor which acts as a capacitive layer. Example conductors include copper foil, polychlorinated biphenyl (PCB), and indium tinoxide (ITO). In other embodiments, other conductors can be used. The sensor layer can include a plurality of capacitive layers (which may be separated by corresponding insulating layers). The capacitive sensors can be provided in a variety of configurations including linear, grid, spiral, or radial, as shown in example embodiments 940A-940D in
The base layer 960 serves as a mount for the sensor layer and the overlay layer. Generally, the sensor layer is mounted to a top surface of the base layer. The overlay layer is mounted to the base layer such that the bottom surface of the overlay layer contacts the sensor layer. The base layer can be formed of a conductive material such as a conductive plastic. Example conductive plastics include polyethylene and polypropylene. The base layer can also house one or more output devices such as a speaker or other audio device 970 that produces sound, and/or a light or other visually perceptible output device 975 based on inputs from the sensor layer. The base layer can also house a control circuit described below.
In example embodiments, the capacitive touch device includes an electronic control circuit or system 980. The control system 980 can include a processor and memory. The processor may be implemented as a specific purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a group of processing components, or other suitable electronic processing components. The memory may comprise one or more devices (e.g., RAM, ROM, flash memory, hard disk storage) for storing data and computer software code for completing and facilitating the various user or client processes, layers, and modules described in the present disclosure. The memory may be or include volatile memory or non-volatile memory and may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures of the inventive concepts disclosed herein. The memory is communicably connected to the processor and includes computer code or instruction modules for executing one or more processes described herein. The memory optionally includes various circuits, software engines, and/or modules that cause the processor to execute the systems and methods described herein, including controlling operation of output devices as described herein. The control circuit or system can control operation of the output device. For example, the control circuit or system can output a signal to the speaker to play a sound based on a particular area of the sensor layer being triggered. The control circuit or system can include a sound database. The control circuit or system can receive the sounds to be played from a remote source (e.g., via communications electronics such as Bluetooth). The control circuit or system can cause a visual output to display icons, animations, or other visual indicators corresponding to commands to be received by the capacitive touch device. The control circuit or system receives a sensor signal from the sensor layer. The control circuit or system can extract a location of the user input from the sensor signal. For example, the sensor signal may include the location of the user input (e.g., a two-dimensional coordinate location corresponding to the surface of the overlay layer). The control circuit or system can determine the location of the user input based on the sensor signal; for example, the sensor signal may include one or more voltage values which the control circuit can use to retrieve the location of the user input from a database (e.g., lookup table stored in a database) mapping voltage values to user input locations. The control circuit or system can determine a command indicated by the user input based on the location of the user input. For example, the control circuit or system can perform a lookup in a command database based on the location of the user input to determine the command. The control circuit or system can control operation of the output devices based on the command. In example embodiments, the toys can include adjustment knobs including volume adjustment. The toys can also include lighted displays. The lighted displays can be activated to guide the child through a series of notes.
The control system optionally generates one or more output modes. For example, a startup mode may be initiated upon switching the device on, generating a sound output such as a wake-up melody or a voice greeting. One or more operational modes may be activated by actuation of a switch or by a sequence of one or more user input contacts upon the overlay panel to trigger the capacitive touch sensors. For example, the control system may generate a play-along mode which activates one or more system-generated melodies or songs, which the user can play along with or accompany by one or more user input contacts upon the overlay panel to trigger the capacitive touch sensors to play user-generated sounds and/or generate light outputs along with the system-generated melodies or songs. The control system may also generate a free-play mode, in which the user generates melodies, songs or other output based on one or more user input contacts upon the overlay panel. The control system may also generate a user-prompting mode, wherein after a predetermined period (for example 10 or 15 seconds) of inactivity, a sound or visual output is generated to catch the user's attention. The control system may also generate an indexed play mode, wherein the system sequentially indexes through a playlist or series of songs or melodies, based on a system-initiated and/or user-initiated sequence. The control system may also generate a shut-down mode based on user inactivity and/or switching the device off, generating a shut-down melody or voice farewell. The system may also include one or more language databases, and allow user selection of the operational language, for example to switch between English, Spanish, Chinese, and/or other languages. The system optionally also includes recordable memory, allowing a user to record their activity, for example a sound recording of music and/or voice, and to selectively play back the recording. In further embodiments, the system may connect or interface with one or more external databases, artificial intelligence (AI) engines, the Internet, or other sources of information, to relate user input to relevant system output and/or to prompt additional user input. The system optionally also may include one or more wired or wireless (e.g., Bluetooth, Wi-Fi, cellular, IR, RF, etc.) communication systems, allowing the system to communicate with one or more external devices. For example, one user may play on a toy drum device according to an example embodiment of the present disclosure, while another user plays on a toy guitar device according to an example embodiment of the present disclosure, and another user plays on a toy piano device according to an example embodiment of the present disclosure, either in the same or remote locations, and the devices communicate with one another to coordinate multiple users' inputs and generate a combined multi-user output.
In example embodiments, the system of the present disclosure can be implemented in any of a variety of particular applications, in the form of different devices, systems and apparatus, enabling various modes and methods of use. For example, the system can be configured in the form of a children's toy, to resemble a range of devices such as musical instruments including a xylophone, a piano, a shaker or speaker, a guitar or ukulele, or other instrument, to generate musical sounds and/or other output. In other embodiments, the system may be configured in the form of a tablet or laptop computer, with sensor inputs generating voice, audio and/or visual outputs. The provision of a natural or simulated wood user input panel or surface may induce a perception of higher quality or improved performance among potential consumers, in comparison to products incorporating plastic or other synthetic user interface materials. In addition, the provision of a substantially continuous seamless exterior user input or interface surface, without significant crevices or recesses in or around the user input areas, prevents the accumulation of dirt, food residue or other debris, facilitates easy cleanup, and reduces the potential for debris to interfere with the product's operation. In alternative example embodiments, the provision of a wood user interface surface allows capacitive touch sensors to be incorporated into a variety of other product formats, within the scope of the present disclosure. For example, a desk, table, chair, workstation or other apparatus may comprise a wood work surface overlaying one or more capacitive touch sensors, and can function as a user interface with a computer, television, display screen, light source, audio device, or other output device, allowing the user to selectively control operation of the output device by contact with the wood user interface or user input surface. Similarly, a flooring panel or board may incorporate a wood contact surface overlaying one or more capacitive touch sensors in communication with a computer or other electronic control system, allowing the flooring material to identify the presence of one or more persons walking over an area and serving as an alarm system, personnel monitor, foot traffic counter, presence sensor, etc. In similar fashion, a customer display or informational sign may incorporate a wood display surface overlaying one or more capacitive touch sensors, and can function as an interactive customer display or informational sign.
Example components of the orchestra toy 1100 may include:
In “Freestyle” mode, pressing the center button activates a basic backer beat (percussive, and probably MIDI) in a specific genre—hip hop, rock, jazz, pop, world, etc. Each of the six cap touch graphics, when touched, overlays a genre-appropriate musical motif on top of the beat and the touched pad's corresponding LED flashes with the overlay for visual feedback. Most of the overlays are short instrumental loops (could be .wav or a sample) that support the underlying beat theme, but some pads may unmute a MIDI channel. When touched again, they may change the MIDI channel to something else, as opposed to muting the channel. Each backer beat theme optionally has a corresponding array of unique overlays. Pressing the center button again activates a new genre backbeat and all of the loop/MIDI overlays change to align with the theme of that particular backer beat. Loop overlays are the same for each character for each backer beat, or alternatively may be playlisted for depth. In “See N Say” mode, the center button press activates a “virtual spin” of the circular LED array, accompanied by SFX. When the “spinning” LED's stop, voice content and supporting sounds specific to the associated graphic pad will play. Touching the graphics over the cap pads will play similar content directly. Call outs may describe/reinforce a specific content suite (Animals!, Instruments!, etc.) on each spin. In “Silly” Mode, silly sounds supporting the graphics play when the cap pads are touched. This may optionally be extended to a Silly Composer mode, similar to Freestyle mode or even a traditional Composer Mode. Backing melody can be activated by the center button and may be nursery themed and supported with flashing LEDs.
Example components of the guitar toy 1200, 1250 may include:
In Free Play mode, sounds played by the guitar 1200, 1250 vary depending on how it is played. In example embodiments, sounds played will integrate with a backer melody when activated by the actuator button. In example embodiments, there are two string triggers, with the upper trigger playing a bass note and the lower trigger the massed strum sound allowing variability when playing; down and up-strumming will produce different sounds, and the user can noodle either trigger to hear bass or strum/treble and a fast downward stroke will play a power chord. In example embodiments, normally, all sounds are in the key of G, but touching the fret triggers while strumming can change the played key to D, C, or E-(TBC). Alternately, the fret keys can overlay different guitar styles loops when no backer melody is playing—Blues slide guitar, Rock arpeggio riffs, Van Halen tapping technique, whammy bar tremolo etc. In example embodiments, the whammy bar adds additional guitar effect overlays to the overall mix. In Guided Play Mode strumming will initiate a simple backer (autoplay) and the LEDs indicate which Fret keys to touch to create a melodic composition. If a backer melody is activated, the guitar will indicate via LED which chords to touch and when, to promote the appearance that the user is playing guitar. If an incorrect chord is touched, the IC can immediately adjust key to play in-key with the backer melody. In example embodiments, the backer melodies run 20-30 seconds and are realized in different styles. The played guitar sound could also vary with each melody—electric, acoustic, banjo, etc. Sound Mode (optional) is intended for the youngest infants, where the two string triggers are bonded together into a single trigger that activates simple backing instrumentation and the fret triggers overlay different instrument loops. This approach is fundamentally different from un-muting pre-composed guitar MIDI tracks within the backer melody and should provide enhanced free form play. The blue actuator button can still play/index through simpler backers with fewer instruments and can attempt to match key by pitching the overlays. The intent is to make it very easy to play and achieve harmonious output.
Example components of keyboard toys 1300, 1350 may include:
Freeform play mode allows the child or other user to experiment with a two-octave piano. The character/instrument touch pads flanking the sides of the keyboard will change the instrument voice. Instruments simulated by the keyboards 1300, 1350 may include, for example, piano, synthesizer, Hammond Organ and Hip-Hop mode. Hip Hop mode may include a sound bank that plays iconic motifs from the Hip Hop genre on part of the keyboard. In Learn to Play mode, the Piano can play rudimentary, pre-defined sequences that prompt the toddler or other user to play the sequences back in similar fashion to a musical Simon toy, supported by LEDs and possibly supported by voice. The character pads may also change instrument or change the voice in Learn to Play mode. Teaching applications or modes of use, optionally termed musical IQ, may call out musical concepts (scale, motif, chord, pitch, arpeggio, etc), followed by quick demonstration of the musical concept. In example embodiments, engaging the Play Assist function may automatically and quickly correct any key input to the “correct” key input, with corresponding LED flashes and sounds. In Silly Mode, the Cap Touch Character pads that change the Piano's voice may change the keyboard's voice to unique silly sound banks of animal sounds, supporting SFX and instrument sounds. Key presses are reinforced with associated LEDs and the played sounds. Backer melodies activated by the blue actuator button may be traditional nursery songs or other content. Play Assist functionality may optionally be provided.
Example components of the table toy 1400 may include:
Melody Mode allows the infant or other user to sequentially step through pre-composed melodies in various styles by activating subsets of instruments in the mix for short durations. In example embodiments, pressing the center blue actuator button will play individual melodies spanning multiple musical genres, and as the melody plays, LEDs corresponding to each instrument will flash when the instruments play notes. In example embodiments, touching one or more different instrument icons when a melody is playing will mute all of the other playing instruments as the touched instruments continue to execute the melody for some interval (for example 2-4 seconds). Subsequently, pressing additional instruments will play those instrument sounds for the short interval until the infant has stepped through the entire melody or the melody times out. The Table's Loop Mode allows multiple percussion instruments to play together, optionally with a limitation of only four instruments playing simultaneously and with each percussion track supported visually by the Instrument Icon's adjacent LED. The center blue actuator button changes the percussive mix to match an alternate style—e.g., reggae, ska, jazz, country, blues, etc. Additionally, the outer instruments can play 4 second or other timed solo loops, appropriate to the current musical genre, on top of the executing mix. The piano allows overlay play in key with the executing outer instrument loops (if active) again overlaying the playing beat style. The inner percussive instruments may not change key. Mood Mode provides four mood themes, selected by the blue actuator button, for example including Energetic, Peaceful, Epic and Quirky modes. Pressing the actuator button optionally allows a user to hear an example of what the mood can sound like with a selection of instruments. For each mood, instrument sounds are extrapolated to similar sounds—where the maraca can be rain, a rattlesnake a salsa rhythm, etc. The trumpet could be a car horn, siren, dinosaur roar, etc., similar to a sound effect board suitable for small children. A Free Play mode optionally plays short example sections to demonstrate possibilities to the user.
In example embodiments, toys according to the present disclosure may help children develop both fine and gross motor skills and introduce child to color and musical note identification. The toys may optionally interact in multiple languages, for example, English, French, Spanish, etc. The toys may include visual (lights, display screen, etc.), audible (melodies and other sound effects), and/or tactile (buzzer, surface features, etc.) interactivity features.
