- the computer program linked to the processor 503 In order for the computer program linked to the processor 503 to direct card 501 to light up its LED lights 516 , the following process is applied. Firstly, once the player chooses to play the melody they have created, they must press the play button 506 or the replay button 507 . The processor 503 plays the melody according to the type of music cards 501 and their relative location on the music chord lines. As each note is being played, the computer program is configured to instruct the central RF antenna 504 to send an RF signal to the targeted music card 501 . As with the embodiment in FIG. 4 , the RF signal contains RF data containing both the UID of the targeted card 501 as well as the output command instruction directed at the music card(s)'s 501 LED light 516 .
- the RF signal transmitted by the central RF antenna 504 also has enough RF energy to power on the music card(s)'s 501 electronic module 509 .
- the RF signal is received by the second RF antenna 513 of all music cards 501 placed within the broadcasting area of the central RF antenna 504 .
- the RF signal is converted to electric power by the RF energy harvesting modules 514 , which provides power to the MCU 517 and LED light of the card 501 whose UID matches that of the received RF signal's UID information (see below).
- the music cards 501 will receive and decipher the data contained in the same RF signal via their first RF antenna 511 and the microcontroller 518 .
- the RF signal transmitted also contains the UID of the card 501 the computer program is targeting as well as the output command instructions affiliated to that UID.
- the output instruction is to light up the targeted music card's 501 LED light 516 . If the music card 501 does not match its UID (contained in the microcontroller 518 ) with the UID data contained in the RF signal, the card 501 will go into an idle mode awaiting the computer system's next RF signal.
- the microcontroller 518 will record the corresponding output command instruction within its writable data storage device 519 and activate the MCU 517 .
- the MCU 517 Upon activation, the MCU 517 will proceed to process the output command instruction, which in this case is to light up the LED light 516 for a predetermined amount of time (e.g., the duration of the music note in question). In such a way, the player is provided with the real-time visual feedback as to what music note is being played.
- FIG. 6 is an exemplary schematic diagram illustrating interactive parts used in a miniature train set in accordance with one embodiment of the present invention.

- These interactive parts may take many forms and designs such as miniature traffic lights 602 , miniature street lights 603 , miniature building lighting 604 , miniature billboards 605 and miniature train signals 606 .
- the computer system's RF antenna broadcasting range encapsulates the whole area of the miniature train set environment 601 which allows for any interactive part 602 , 603 , 604 , 605 , 606 placed within this range to be directed by the computer program linked to the processor.
- Each interactive part 602 , 603 , 604 , 605 , 606 is equipped with the same electronic module 607 described for the objects of the previous embodiments but, depending on the part, the output devices may include one or more LED lights or acoustic device (e.g., a beeping device).

- the computer program linked to the processor is configured to track the relative progression of the miniature trains along the track. Whenever a train approaches a train signal 606 , the computer program determines whether the train signal should either be red (thus stopping the train on its tracks) or green (allowing the train to proceed), and the processor is configured to direct the train signal 606 flashing either LED lights 614 , 615 . Moreover, as the train signal is about to turn from green to red, the train signal 506 is directed to start making a beeping sound via its beeping device 616 (thus mimicking the sound that a real train signal makes).
- the manner in which the train signal 606 is directed by the processor is as follows.

- The entire disclosures of each of the above applications are incorporated herein by reference.
- The present invention relates to a system and method for directing an object that has no battery generating a sensory output to a user, with the interactivity of the object powered by an RF-DC energy conversion module.
- The abundance of inexpensive and increasingly miniaturized computer processors has greatly influenced recreational and educational games allowing for a high level of interactivity between the user and devices.
- Typically, computerized games provide players with a visual display of the game activity through an electronic display system such as a pixilated flat panel display or touch screens. However, such displays lack a three-dimensional nature that prevents the physical interaction inherent in toys and the like. For instance, the traditional toy blocks may use one or more movable game piece that players (especially young ones) find more “natural” and easier to interact with during their play or learning experience. On the other hand, traditional tools and toys often lack audio, visual or other forms of sophisticated feedback that computerized programs and game play can offer to users and players. Therefore, a method that can combine both computerized technology and physical objects can effectively enhance a user's experience by allowing their physical actions to be interpreted by a computer system so as to provide real-time feedback to the user in the form of a multitude of sensorial accessories such as video and/or audio outputs.
- The present invention provides a system and method for directing multiple small scale physical objects such as cards, blocks or miniature figurines that can interact with a user through various feedback mediums such as LED lighting, speakers, vibrators, or display devices that are operable with an electric power input less than 100 milli-watt. The objects further power their circuitry through RF to DC energy conversion technology.
- In effect, the present invention provides a system and method for directing one or more objects that can effectively enhance traditional tools and playing objects such as cards and blocks by adding an interactive dimension to them. This also allows objects to be wirelessly connected to computer systems which, in turn, can be connected to the internet/servers, thus adding another level of interactivity between the objects and the user.
- The present invention provides a system for directing an object that has no battery to generate a sensory output to a user through wireless means. The object does not have an embedded battery but derives power from radio frequency electromagnetic wave energy through the use of an RF energy harvesting module. Once selectively activated, the object provides an output to its user. Such output can be utilized in a variety of entertaining, useful or productive means.
- The system includes a plurality of objects and a processor that is configured to send an instruction to objects. A computer program is further operatively linked to the processor and is configured to generate an instruction targeted at a specific object having a specific UID.
- The object further includes an RFID tag containing a first RF antenna and an RFID chip containing a microcontroller, a writable data storage means and an unique identification code (UID) of the object, a micro computer unit (MCU) connected to the microcontroller, a miniature sensory device connected to the MCU, a second RF antenna, and an RF energy harvesting module that is connected to the second RF antenna and provides electric power to the MCU and the sensory device.
- Upon receiving an instruction by the first antenna, and upon electric power being provided to the MCU and the sensory device by the RF energy harvesting module, the microcontroller of the RFID tag is configured to activate the MCU of the object if the aforementioned object's UID matches the targeted UID embedded in an instruction, and the MCU is configured to direct the sensory device producing a sensory output to a user according to the instruction.
- This invention is useful in a variety of fields that require a sensory feedback to an end-user, including education, entertainment and increasing productivity.
- The following description includes discussion of figures having illustrations given by way of example of implementations of embodiments of the invention. The drawings should be understood by way of example, not by way of limitation. As used herein, references to one or more “embodiments” are to be understood as describing a particular feature, structure, or characteristic included in at least one implementation of the invention. Thus, phrases such as “in one embodiment” or “in an alternate embodiment” appearing herein describe various embodiments and implementations of the invention, and do not necessarily all refer to the same embodiment. However, they are also not necessarily mutually exclusive.

FIG. 4 is an exemplary schematic diagram illustrating cards used in conjunction with a computer system in order to play a word spelling game in accordance with one embodiment of the present invention. - In the embodiment describe in
FIG. 4 the objects includecards 401 used in conjunction with acentral device 402. The central device includes aprocessor 403 embedded into it which is operatively linked to acentral RF antenna 404 and anaudio system 405. The computer program operatively linked to theprocessor 403 is further configured to generate an instruction targeted at aspecific card 401 having a specific UID. Thecentral RF antenna 404 has a clearly defined broadcasting area 406 (depicted by the dotted circle inFIG. 4 ) in which anycard 401 placed within thisarea 406 can be powered on and have its LED lights switched on or off. - Each
card 401 of the embodiment described inFIG. 4 has a letter of the alphabet imprinted on it and anelectronic module 407 embedded within it. Theelectronic module 407 includes anRFID tag 408 containing afirst RF antenna 409 and anRFID chip 410 containing amicrocontroller 417, the object's UID as well as a writabledata storage device 418. The electronic module further includes asecond RF antenna 411, an RFenergy harvesting module 412, a micro computer unit (MCU) 416 and two LED lights (one green 414, one red 415). The RFenergy harvesting module 412 is operatively connected to thesecond RF antenna 411. TheMCU 416 is operatively connected to themicrocontroller 417, RFenergy harvesting module 412 and the twoLED lights - The method of the embodiment described in
FIG. 4 is the following. Theprocessor 403 is configured to broadcast to the player audio recordings relating to spelling questions. Such recordings may include the question “do you know how to spell bed?” These questions prompt the player to place thecards 401 that they believe consist of the correct answer within thebroadcasting area 406 of thecentral RF antenna 404. After a time limit, theprocessor 403 is configured to instruct thecentral RF antenna 404 to send an RF signal to anycards 401 within the central RF antenna's 404broadcasting range 406. The RF signal in question contains RF data regarding both the UID of thecards 401 that the computer program is targeting and the command instruction directed at the card(s)'s 401LED lights central RF antenna 404 also has enough RF energy to power the card(s)'s 401 electronic circuitry. Once transmitted, the RF signal is received by thesecond RF antenna 411 of the card(s) 401 placed within thebroadcasting area 406. Afterwards, the RF signal is converted to electric power, which is provided to theMCU 416 andLED lights energy harvesting module 412. Simultaneously, the card(s) 401 receives and deciphers the data contained within the same RF signal via thefirst RF antenna 409 and themicrocontroller 417. The RF signal transmitted by thecentral RF antenna 404 contains both information about the UID of the card(s) 401 that theprocessor 403 is targeting and the output instructions affiliated to that particular UID. Within the confines of the present embodiment, all UIDs are targeted but with two distinct output command instructions. These being to switch eitherLED lights microcontroller 417 will record the corresponding output command instruction for theircard 401 within its writabledata storage device 418. Once theMCU 416 of the card(s) 401 has been powered up, it will proceed to send the output command instruction to the LED lights 414, 415. Again, this command will be dependent on whether the card is correct (causing to light up the green LED light 414) or incorrect (causing to light up the red LED light 415). In such a way, the player is provided with real-time visual feedback as to whether they have made a correct card selection. - Looking at the four
cards 401 placed within thebroadcasting area 406 of thecentral RF antenna 404 inFIG. 4 , one can see how the aforementioned game will pan out. In this scenario, we can assume the spelling question is “Do you know how to spell the word bed?”, and the player places not only the three correct cards (i.e., the letters b, e, and d) 401 but has also a wrong one (i.e., the letter s). The feedback provided to the player will be having the correct three cards'green LED lights 414 lighting up, and the incorrect card's red LED light 415 lighting up. - There is a multitude of design alternatives for the embodiment described in
FIG. 4 , but one design worth mentioning is to have LED lights embedded in the cards to light up in sequence. This design is particularly useful in helping the user understand the order of the letters relative to one another. Referring back to the scenario inFIG. 4 with the audio broadcasting the question “Do you know how to spell the word bed?”, the computer program is configured to instruct theprocessor 403 to send separate RF signals to instruct the three cards (e.g., the letters b, e and d) to light up their LED at differing time intervals and in an appropriate sequence. In this manner, thecard 401 with the letter “b” imprinted upon it will light up first, which can be accompanied by an audio rendering of the letter's pronunciation; the card with the letter “e” will light up next, and finally the card with the letter “d” will light up. In such a manner, the user is provided with a visual aid in understanding the correct order of the letters within a word. - The embodiment described above includes an interactive game for young children playing freely with letter cards within a designated area. There are clear educational merits to such a game as it allows children to experiment with letter combinations and learn spelling in a fun and non-restrictive play environment. Furthermore, any language can potentially be chosen for this string-of-letters/word association game.
- Although the abovementioned embodiments make use of language-related symbols, it is understood that there are a large number of other options that can be implemented within the premise of the present embodiment. For example, virtually all existing languages, both alphabet-based and non alphabet-based, can be used for the components of the design of the cards. Another potential alternative embodiment involves mathematics games which uses Arabic numerals (or other such as Chinese or Latin numerals) as the symbols printed on the surface of cards. Other card designs involve pictures instead of symbols. The pictures often used on flash cards such as animals, careers, vehicles or the like are all potentially viable options and considered within the scope of the present invention.

FIG. 5 is an exemplary schematic diagram illustrating cards used in conjunction with an interactive surface capable of detecting the UID and location of cards placed upon its surface in order for a player to compose music in accordance with one embodiment of the present invention. - In this embodiment,
cards 501 with music-related symbols imprinted upon them are placed upon aninteractive surface 502 in order to create a melody. Theinteractive surface 502 is operatively linked to aprocessor 503. Theinteractive surface 502 also includes one or more sensors that are also operatively linked to theprocessor 503 and which are capable of detecting the UID and location ofcards 501 placed on top of theinteractive surface 502. Theinteractive surface 502 further includes acentral RF antenna 504 and anaudio system 505 that are operatively linked to theprocessor 503. Theinteractive surface 502 inFIG. 5 also has a number of functional buttons in order for the player to interact with. These buttons include theplay button 506, thereplay button 507 and thepause button 508. - The
music cards 501 each has anelectronic module 509 embedded into them. Theelectronic module 509 includes anRFID tag 510 containing afirst RF antenna 511 and anRFID chip 512 containing amicrocontroller 518, the card's UID and a writabledata storage device 519. Theelectronic module 509 further contains asecond RF antenna 513, an RFenergy harvesting module 514, a micro computer unit (MCU) 517 and oneLED light 516. The RFenergy harvesting module 514 is operatively connected to thesecond RF antenna 513. TheMCU 517 is operatively connected to themicrocontroller 518, the RFenergy harvesting module 514 and theLED light 516. - The method for the embodiment described in
FIG. 5 is the following. As a player selects and placesmusic cards 501 upon theinteractive surface 502 within the designated areas (i.e., on top of the music chord lines), the sensor system of theinteractive surface 502 detects the location and UID of eachcard 501 and transmits this data to theprocessor 503 for processing. The computer program operatively linked to theprocessor 503 determines the string of music notes (by matching the UID of thecards 501 with their accompanying music symbol) and deduces in real-time the music melody that the player is creating. Finally, once a player is satisfied with the pattern ofmusic cards 501 that he/she has created they can press theplay button 506 in order to have theprocessor 503 play the melody back to the player via theaudio system 505. - Similarly to the previous embodiment depicted in
FIG. 4 , the computer program connected to theprocessor 503 is able to direct each music cards' 501LED light 516. Whenever the player chooses to play their melody the computer program is configured to direct theLED lights 516 of each music card sequentially lighting up according to when a music note is being played. In such a manner the player can recognize which music symbol matches which sound through direct visual feedback (e.g., LED lights). - In order for the computer program linked to the
processor 503 todirect card 501 to light up itsLED lights 516, the following process is applied. Firstly, once the player chooses to play the melody they have created, they must press theplay button 506 or thereplay button 507. Theprocessor 503 plays the melody according to the type ofmusic cards 501 and their relative location on the music chord lines. As each note is being played, the computer program is configured to instruct thecentral RF antenna 504 to send an RF signal to the targetedmusic card 501. As with the embodiment inFIG. 4 , the RF signal contains RF data containing both the UID of the targetedcard 501 as well as the output command instruction directed at the music card(s)'s 501LED light 516. Moreover, the RF signal transmitted by thecentral RF antenna 504 also has enough RF energy to power on the music card(s)'s 501electronic module 509. Once transmitted, the RF signal is received by thesecond RF antenna 513 of allmusic cards 501 placed within the broadcasting area of thecentral RF antenna 504. Afterwards, the RF signal is converted to electric power by the RFenergy harvesting modules 514, which provides power to theMCU 517 and LED light of thecard 501 whose UID matches that of the received RF signal's UID information (see below). At the same time, themusic cards 501 will receive and decipher the data contained in the same RF signal via theirfirst RF antenna 511 and themicrocontroller 518. Similarly, the RF signal transmitted also contains the UID of thecard 501 the computer program is targeting as well as the output command instructions affiliated to that UID. In the present embodiment, only one UID (and therefore only one music card 501) is targeted at a time, and the output instruction is to light up the targeted music card's 501LED light 516. If themusic card 501 does not match its UID (contained in the microcontroller 518) with the UID data contained in the RF signal, thecard 501 will go into an idle mode awaiting the computer system's next RF signal. If themusic card 501 does indeed match the RF signal UID with its own UID, themicrocontroller 518 will record the corresponding output command instruction within its writabledata storage device 519 and activate theMCU 517. Upon activation, theMCU 517 will proceed to process the output command instruction, which in this case is to light up theLED light 516 for a predetermined amount of time (e.g., the duration of the music note in question). In such a way, the player is provided with the real-time visual feedback as to what music note is being played. -
FIG. 6 is an exemplary schematic diagram illustrating interactive parts used in a miniature train set in accordance with one embodiment of the present invention. - In the embodiment depicted in
FIG. 6 , the objects include interactive parts of a miniaturetrain set environment 601 used in conjunctions with a processor connected to a central RF antenna. The interactive parts are a part of the miniature train set environment and are directed to independently activating their output devices (e.g., green, red or orange lights for the miniature traffic lights dotted across the landscape) by the processor in accordance with a specific computer program (e.g., the timing of the traffic lights or the time building/street lighting is switched on in order to recreate the time of day). These interactive parts may take many forms and designs such asminiature traffic lights 602, miniature street lights 603,miniature building lighting 604,miniature billboards 605 and miniature train signals 606. The computer system's RF antenna broadcasting range encapsulates the whole area of the miniaturetrain set environment 601 which allows for anyinteractive part interactive part electronic module 607 described for the objects of the previous embodiments but, depending on the part, the output devices may include one or more LED lights or acoustic device (e.g., a beeping device). - Each individual interactive part contained in the embodiment described in
FIG. 6 can be independently directed to activate their output devices wirelessly by the processor in accordance to the specific computer program. There are a number of potential designs for the interactive parts and the accompanying computer program but, for the sake of simplicity, this document will specifically explain how the miniature train signals 606 operate. - Each
miniature train signal 606 has anelectronic module 607 embedded into it. Theelectronic module 607 includes anRFID tag 608 containing afirst RF antenna 609 and anRFID chip 610 containing amicrocontroller 618, the train signal's 606 UID and a writabledata storage device 619. Theelectronic module 607 further includes asecond RF antenna 611, an RFenergy harvesting module 612, two LED lights (one red 614 and one green 615), abeeping device 616 and a micro computer unit (MCU) 617. The RFenergy harvesting module 612 is operatively connected to thesecond RF antenna 611. TheMCU 617 is operatively connected to themicrocontroller 618, the RFenergy harvesting module 612, the twoLED lights beeping device 616. - The method for the miniature train signals 606 illustrated in the embodiment described in
FIG. 6 is the following. The computer program linked to the processor is configured to track the relative progression of the miniature trains along the track. Whenever a train approaches atrain signal 606, the computer program determines whether the train signal should either be red (thus stopping the train on its tracks) or green (allowing the train to proceed), and the processor is configured to direct thetrain signal 606 flashing eitherLED lights train signal 506 is directed to start making a beeping sound via its beeping device 616 (thus mimicking the sound that a real train signal makes). - Similar to the previous embodiments the manner in which the
train signal 606 is directed by the processor is as follows. According to user defined rules (e.g., the timing and/or proximity of trains approaching the train signal) the processor is configured to send an RF signal to thetrain signal 606 by targeting its specific UID. Although this RF signal is received by all the interactive parts within the central RF antenna's broadcasting area, since only one UID is contained within the RF signal, all other interactive parts disregard this signal and go back into a sleep mode. Once the targeted train signal's 606electronic module 607 is powered on and receives and processes the RF data, the LED lights and beeping device are switched on or off according to the instructions sent by the computer program. - This embodiment allows for the interactive parts being powered on and directed without the use of cumbersome and costly wiring that is currently the norm for these kinds of miniature sets.
