With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views,
In example embodiments, the toy body 102 comprises a central shell or base portion, for example having one or more shell portions configured for assembly together to define an internal housing chamber therein. Each of the plurality of interactive arms or tentacles 104 (i.e., 104a-h) includes a user input area 114 (i.e., 114a-h) comprising a capacitive discharge conductive material and a capacitive touch sensor 106 (i.e., 106a-h) affixed beneath each respective user input area. For example, the capacitive touch sensors 106 are in operative contact with for example an internal, underside, and/or hidden surface of the interactive arms 104, such as shown in
According to example embodiments, the interactive arms 104 are activated by making contact with the user input areas 114 such that said contact is detected by the capacitive touch sensors 106. When a user contacts the user input areas 114, the capacitive touch sensors 106 detect the change in capacitance resulting from the user contact with the capacitive discharge conductive material and provide an electronic input signal to the input-output control system or integrated circuit indicating a user contact. The input-output control system or integrated circuit is preferably mounted inside or on the toy body 102. In example embodiments, the input-output control system is generally configured to receive the input signals generated by the capacitive touch sensors and to generate a responsive output signal. The children's toy preferably also includes one or more output devices configured to receive the output signal from the control system and generate user-perceptible outputs in response thereto. Optionally, the input-output control system may include one or more integrated circuits such as application specific integrated circuits incorporating onboard microprocessor(s), digital memory, and/or application software for carrying out capacitive user input touch sensing, interactive voice/melody output, light output, and/or other input/output features of the toy 100.
The drive system of the interactive toy 100 generally comprises one or more wheels 108 driven by one or more motors 132 configured to receive output signals from the input-output controllers and operate in response thereto. For example, the drive system may include a single motor configured to operate or move the interactive toy, or the drive system may include two or more cooperatively or independently operated motors. In some example embodiments, one or more motors may be configured to operate and/or move the interactive toy without wheels. Optionally, the interactive toy may also include other non-driven wheels or castors for balance and/or support. In the depicted embodiment, for example, the interactive toy 100 includes two motorized wheels 108a and 108b (as shown in
According to example embodiments, the wheels 108a and 108b are preferably arranged and configured to allow the interactive toy 100 to spin about a vertical axis A, as shown in
In example embodiments, the speed, acceleration, duration, and/or amount of rotation or spin may also be dictated by the distance between the user input areas 114, or number of interactive arms between the user input areas, in successive user contacts. For example, a sequence of user inputs including user input areas 114a and 114d may result in a rotation of faster speed and/or acceleration than a sequence comprising user input areas 114a and 114b. Conversely, successive user contact with user input areas 114a and 114b may cause the interactive toy 100 to spin at a slower speed and/or acceleration than successive user contacts made with user input areas 114a and 114d. In some example embodiments, the rotation of the motors and/or interactive toy 100 depends on the variation in musical note values. Preferably, the interactive toy 100 is configured to rotate or spin enough for the user's hand to make contact with each successive user input area without the user having to move the user's hand. For example, once a user initiates the first contact, the interactive toy will spin so that the next user input area comes into contact with the user's hand without the user moving the user's hand. As long as the user does not move his/her hand, the interactive toy will seamlessly continue to create a fluid play experience as the toy continues to spin.
According to example embodiments, the interactive arms or tentacles 104 are hingedly connected to the toy body 102 so that even if the user's hand is in the way of the interactive arms as the interactive toy spins or rotates, the interactive arms slide around the user's hand and continue spinning. Accordingly, as long as the user's hand remains relatively in the same position, the user's hand continues to make contact with each successive user input area 114 and thus the interactive toy 100 continues to spin in the same rotational direction. The interactive toy comes to a stop only once the user's hand is moved away and no further user contact is made with the user input areas 114.
As shown in
In some example embodiments, the different learning materials may be printed, painted, and/or affixed directly onto the interactive arms 140. It is to be understood that the sleeves 140 may comprise other learning materials/features printed or affixed thereon, such as for example pictures of different animals, different words, alphanumeric characters, and/or symbols, or other suitable material, and/or any combination thereof.
In some example embodiments, the children's toy 100 may also include one or more other output features such as for example, speakers, lights, actuators, or other output devices in electronic communication with the electronic input-output control system for additional visual, audio, and/or haptic effects. For example, in the depicted embodiment, each user input area 114 is mapped or corresponds to a specific note of a musical scale, for example as shown in the table below.
Accordingly, when contact is made with the user input areas, the interactive toy produces or plays the corresponding notes through speaker 118. In alternative embodiments, the interactive toy 100 may be configured to produce sounds other than musical notes in response to user inputs.
In example embodiments, the children's toy 100 further comprises a lighted display or face 116. In example embodiments, the lighted face 116 comprises a semi-translucent panel with one or more light emitting devices, such as for example light emitting diodes, configured to light the semi-translucent panel. In example embodiments, the light emitting devices are responsive to the user inputs. In yet other example embodiments, the children's toy 100 may further comprise other input features such as for example mechanical switches 124, buttons, actuators, etc. in electronic communication with the electronic input-output control system for selective user control of power on/off, volume control, mode switching, melody activation, and/or other features. Optionally, the interactive toy 100 may further comprise a battery compartment 120 for receiving batteries to power the toy and/or an AC power adaptor and electrical cord connection.
Example components of the interactive toy 100 may include:
The interactive motorized toy 100 comprises a plurality of modes of play of escalating complexity and interactivity to accommodate and/or challenge the baby or child as he or she grows. In example embodiments, the interactive motorized toy 100 comprises four modes of play: a Tummy-Time Mode, a Sit-to-Play Mode, a Chase Mode, and a “Dance” mode. The different modes of play are selectable by the slide switch 124b which comprises a selectable position for each mode of play. Generally, in the Tummy Time mode, the interactive toy 100 is configured to play melodies and sounds with flashing lights in a stationary position. In the Sit-to-Play mode, the interactive toy 100 is configured to play melodies and interactive learning content and rotate side-to-side and spin in circles in a stationary position. In the Chase Mode, the interactive toy 100 is configured to inspire the baby or child to move or chase after the toy as the it moves around a room or play area. In the Chase Mode, the toy 100 utilizes its motorized wheels to rotate and move in multiple directions. In the Dance Mode, the toy 100 is configured to play melodies with learning content inspiring baby or child to move and learn as the toy 100 executes complex motion profiles.
In example embodiments, the interactive toy 100 comprises a switch or actuator 124a for powering or activating the toy and controlling the volume of any sound or melody. In the depicted example, the switch 124a is a sliding switch selectable between a “power off” setting, a “low volume” setting, and a “high volume” setting. The toy 100 remains off or without power (i.e., the battery is disconnected from all electronics) until the sliding switch is selectively moved from the “power off” setting to either the “low volume” or “high volume” settings. In the “low volume” setting, the level of sound output from the speaker 118 may be limited to a lower decibel, for example about 58 dBA+/−5 dBA playback level, relative to the sound output level in the “high volume” setting having for example about 64 dBA+/−5 dBA playback level. In other example embodiments, the toy 100 may comprise one or more actuators for controlling the power and volume. For example, the toy 100 may comprise an actuator for powering the toy on and off and a separate actuator for controlling the volume. The actuators may comprise switches, buttons, or other similar suitable components or actuators.
In example modes of use, selectively moving the power-volume control switch into either of the low or high volume settings initiates an automatic start-up sequence. The start-up sequence starts with playing a start-up sound or melody. Immediately after the start-up sound is activated, the integrated circuit or controller activates a callback sound or melody according to the mode of play, or play mode, selected at the time the toy is powered on. Alternatively, the mode of play can be changed as desired while the toy 100 is already powered on by selectively moving the slide switch 124b to the desired setting or position and pressing the top button 126.
In the Tummy Time mode, the toy 100 is configured to rotate in a stationary position while playing sounds, tones, and/or melodies. According to example embodiments, the Tummy Time mode can be initiated from the powered off state by selectively moving the sliding switch 124b to the Tummy Time setting and then selectively moving the sliding switch 124a to either the low- or high-volume setting to power on the toy 100. Alternatively, if the toy 100 is already powered on, the Tummy Time mode can be initiated by selectively moving the sliding switch 124b to the Tummy Time setting and then activating or pressing the top button 126.
Once the Tummy Time mode is initiated, the toy 100 will play a sequence of songs and/or melodies dedicated to the Tummy Time mode (i.e., a Tummy Time initiation audio sequence) for a preset amount of time, for example 1 minute. In some example embodiments, the toy 100 may be configured or programmed with a playlist of additional songs, sound effects, and/or melodies which is played in sequence, or randomly, upon further interaction with the toy 100 (for example, upon activation of the top button 126 and/or other user inputs such as for example user inputs 104). For example, pressing the top button 126 during melody or audio playback may trigger the toy 100 (or more specifically, the integrated circuit) to advance to the next song or audio file in the playlist. Alternatively or additionally, initiation of the Tummy Time mode may trigger or activate one or more light sources of the lighted face 116 to display an array or sequence of dynamically changing and fading colors (i.e., a lightshow) creating a fun visual experience for the baby or child in addition to, or in place of, an auditory experience.
In the Tummy Time mode, the interactive arms or tentacles 104 are configured to mimic keys of a piano, and activating the arms (i.e., touching the user input or contact areas 114a-h such that contact is detected by the capacitive touch sensors 106a-h plays) triggers preset or predetermined visual, auditory, and/or interactive playback or responses. In the depicted example embodiment, a specific note of a piano is assigned to each of the tentacles 104, or capacitive touch sensors 106. For example, tentacle 104a-h and capacitive touch sensors 106a-h may be configured to play individual notes on a C Major Scale and/or show different colors on the lighted face 116, as follows:
It is to be understood that the auditory and/or visual effects may comprise other sounds or sound effects and other colors. For example, the auditory effects may comprise animal sounds or sounds of other instruments. In example embodiments, the toy 100 is further configured to spin or rotate in the direction of the scale played or tentacle activated. For example, if the second input is to the right of the first input, the toy rotates to the right. Similarly, if a subsequent input is to the left of the previous input, the toy rotates to the left.
In the Sit-and-Play mode, the toy 100 is configured to rotate in a stationary position for a 360-degree play pattern around the toy. Pressing any of the interactive arms or tentacles 104 causes the toy 100 to spin 180 degrees clockwise or counterclockwise while playing sounds, tones, and/or melodies. In example embodiments, the toy is configured to alternate spinning in one direction a predetermined number of times (e.g., 3 times) and in another direction another predetermined number of times (e.g., 3 times). According to example embodiments, the Sit-and-Play mode can be initiated from the powered off state by selectively moving the sliding switch 124b to the Sit-and-Play setting or position and then selectively moving the sliding switch 124a to either the low- or high-volume setting to power on the toy 100. Alternatively, if the toy 100 is already powered on, the Sit-and-Play mode can be initiated by selectively moving the sliding switch 124b to the Sit-and-Play setting and then activating or pressing the top button 126.
Once the Sit-and-Play mode is initiated, the toy 100 plays a sequence of songs and/or melodies dedicated to the Sit-and-Play mode (i.e., a Sit-and-Play initiation audio sequence) for a preset amount of time, for example 1 minute. In some example embodiments, the toy 100 may be configured or programmed with a playlist of additional songs, sound effects, and/or melodies which is played in sequence, or randomly, upon further interaction with the toy 100 (for example, upon activation of the top button 126 and/or other user inputs such as for example user inputs 104). In the depicted embodiment, for example, pressing the top button 126 activates sounds and/or melodies from a preprogrammed playlist. Each time the top button 126 is pressed, the toy (or the integrated circuit) cycles through the playlist. Additionally, or alternatively, the toy 100 is configured such that the integrated circuit alternates between a number of learning suites or themes, including for example numbers, shapes, and colors. The toy 100 may be further configured with a sub-feature where only sound effects from the playlist is activated if an input from the top button 126 is detected within for example 0.5 seconds of the last head button activation.
In the Sit-and-Play mode, the interactive arms or tentacles 104 are configured to activate auditory and/or visual effects specific to each tentacle upon activation (i.e., contact detected by the respective capacitive touch sensor 106). Moreover, the auditory and/or visual effects may depend on the learning suite active at the time the tentacles are activated. In example embodiments, for example, activation of each arm 104 may be configured to call out or announce a number when the number learning suite is active; a specific shape when the shape learning suite is active; or a specific color when the color learning suite is active. Additionally, or alternatively, function of the motors and motorized wheels may vary depending on learning suite active at the time the arms are engaged. For example, in example embodiments, the toy 100 alternates between rotating left and right at varying degrees when either the shape or color learning suites are active. If the numbers learning suite is active, the integrate circuit instead operates the motors and motorized wheels in the same manner that they operate in the Tummy Time mode. For example, if a subsequent input is to the left of the previous input, the toy 100 is configured to spin or rotate to the left. On the other hand, if the subsequent input is to the right of the previous input, the toy 100 spins or rotates to the right. In example embodiments, the toy 100 is configured to hold a learning suite until either the toy goes into a standby mode, there has been for example 16 tentacle activations in the same learning suite, or the user manually switches between the different learning suites by activating the top button 126.
In the Chase mode, the toy 100 is configured to move around a support surface or room upon activation of the top button 126. The objective of the Chase mode is to create a “run-away” feature inspiring the user to chase after to the toy. In example embodiments, the toy 100 moves forward, stops to play a sound to encourage the baby or child to chase it, and then moves again. Preferably, the toy 100 comprises means for detecting obstacles, such as for example an infrared sensor 128, while moving forward. If the toy 100 detects an obstacle, it rotates for example 90 degrees either to the right or the left and continues its forward movement. In some example embodiments, the toy 100 may increase speed upon turning to avoid obstacles. In other example embodiments, the toy 100 may comprise means to detect when the toy 100 is trapped or hung up on an obstacle between its tentacles 104. For example, toy 100 may include a sensor for detecting when the motors are not moving forward. If so, the toy 100 rotates side-to-side. The toy 100 may further comprise one or more limit switches, such as for example SPST limit switches, on each motor gearbox to detect positioning and motor function. If no limit switch is hit or engaged as the toy rotates side-to-side, the toy reverses the direction of the motors.
According to example embodiments, the Chase mode can be initiated from the powered off state by selectively moving the sliding switch 124b to the Chase setting and then selectively moving the sliding switch 124a to either the low- or high-volume setting to power on the toy 100. Alternatively, if the toy 100 is already powered on, the Chase mode can be initiated by selectively moving the sliding switch 124b to the Chase setting and then activating or pressing the top button 126.
The toy 100 is configured so that the difficulty of the chase gradually scales up or down depending on whether the child user is successful in capturing the toy or not. In example embodiments, the difficulty level is increased by one level if the child successfully captures the toy twice in a row. On the other hand, the difficulty level is decreased by one level if the child is unsuccessful in capturing the toy. In this way, the toy 100 caters to the abilities of the child user and optimizes the learning experience for the child. For example, according to example embodiments, the toy 100 starts at a difficulty level 1, the default difficulty level when the toy 100 is powered on. If the child user is successful in capturing the toy twice in a row, the difficulty level is increased by 1 level to difficulty level 2. Similarly, if the child successfully captures the toy two more times in a row, the difficulty level is raised to difficulty level 3. On the other hand, if the child is not successful in capturing the toy 100 at difficulty level 2, the difficulty level is decreased to difficulty level 1. In example embodiments, the difficulty levels are defined by the motor speed and the movement patterns, as follows:
In other example embodiments, there may be less than three or more than three difficulty levels and the specific configurations of motor speed and movement patterns for each difficulty level may be configured as desired.
In the Chase mode, pressing the top button 126 triggers different functions depending on whether the toy is moving or stationary when the top button is activated. For example, if the top button 126 is activated while the toy 100 is moving, the toy is configured to stop moving and play a sound or melody from a stored audio playlist (i.e., a Chase Success playlist) indicating that the toy has been successfully captured while spinning in circles. Conversely, if the top button 126 is activated while the toy 100 is stationary, the toy 100 (or the integrated circuit) activates motor function and sound from another playlist indicating to the child user to begin chasing the toy (i.e., a Call-to-Action playlist).
Similarly, pressing or activating the interactive arms 104 in the Chase mode initiates different functions depending on whether the toy 100 is moving or stationary at the time the interactive arms are activated. For example, if an arm 106 is activated while the toy 100 is moving, the toy is configured to stop moving and play a sound from the Chase Success playlist while spinning around in circles. Conversely, if an interactive arm 106 is activated while the toy 100 is stationary, the toy 100 plays a song or melody from the Call-to-Action playlist and performs a brief motorized pattern while the song or melody is playing. Moreover, if the toy 100 is picked up while in the Chase mode, the toy 100 is configured to play an audio file from a Success Phrase playlist and flash multicolored lights on the lighted face 116 and plays a specific sound to announce that the toy has been picked up.
In example embodiments, the toy 100 plays different melodies based on the success or failure to capture the toy in the Chase mode. For example, if the interactive arms 104 or the head or top button 126 are activated before the melody times out and stops playing, the toy is configured to play a prerecorded phrase from the Chase Success playlist indicating the child has successfully captured the toy. Alternatively, if neither the top button nor any of the arms 104 are activated before the melody times out, the toy 100 plays a sound or melody from yet another playlist (i.e., Chase Fail playlist) indicating that the child was unsuccessful in capturing the toy in the allotted time.
In the Dance mode, the toy 100 is configured to move around in front of the baby or child and inspire them to move as the toy 100 executes complex motion profiles, for example as shown in
In the Dance mode, pressing the top button 126 activates sung songs from a stored playlist with accompanied motorized dancing or movements in a specific pattern or path P across the floor or support surface, as shown in
Activating any of the arms 104 in the Dance mode triggers the toy 100 to play sounds from other stored playlists (i.e., a Tentacle Dance playlists) with accompanied motor function. As mentioned above, the tentacles 104 are activated through capacitive touch sensors embedded or coupled to each of the arms. In example embodiments, the tentacles 104 are separated into two playlists. For example, arms 104a-d may be configured to play sounds from a first playlist whereas arms 104e-h are configured to play sounds from a separate second playlist. In other example embodiments, the arms 104 may be separated into more than two playlists.
The toy 100 is configured to keep memory or track of a number of past movement patterns activated by the user and repeat the movement patterns on its own. For example, in example embodiments, the toy 100 keeps track of the last four movement patterns activated. In example embodiments, before the toy 100 plays back the four movement patterns, the toy 100 begins the sequence with playing an initiation sound. In example embodiments, if the toy 100 remains idle for example 15 seconds and under four movement patterns have been activated, it will automatically trigger the activated patterns. For example, if two movement patterns are activated and the toy sits idle for 10 seconds, the toy (or the integrated circuit within the toy) automatically plays the initiation sound and performs the two movement patterns.
Below is an example set of two Tentacle Dance playlists-one playlist for arms 104a-d and another for arms 104e-h.
During the Dance mode, if an arm 104 is activated while a prior melody is playing, the toy 100 plays an overlay sound specific to the arm that is activated. In example embodiments, if the toy 100 tips over, the toy 100 continues to play music but the motor is stopped for example to prevent user hair entrapment. If the top button 126 is pressed during music playback, the toy 100 stops both the music and the motors, and plays a sound to indicate that the music and movement has stopped.
In some example embodiments, at least one of the wheels comprises a floor detection switch (not shown) to detect when the toy is grounded. If the floor detection switch is active for longer than for example 1 second, the toy immediately ceases motor function. On the other hand, the toy 100 will continue to play any sound or music playing at the time until the sound or music is finished. In example embodiments, the music is activated by pressing the top button 126 and the music playlist depends on the mode. Each of the arms is configured to play a unique sound effect that overlay melodies.
