[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62 / 617,506, filed January 15, 2018, and entitled "INTERACTIVE SYSTEMS AND METHODS WITH FEEDBACK DEVICES," which is incorporated herein by reference in its entirety for all purposes.

[0002] TECHNICAL FIELD The present disclosure relates generally to interaction systems and methods. In particular, embodiments of the present disclosure relate to interaction systems and methods that utilize wearable devices to provide feedback to guests at an amusement park. [Background technology]

[0003] Amusement and / or theme parks can include a variety of entertainment attractions. Some existing attractions can provide guests with an immersive or interactive experience. For example, guests can visit areas with a variety of features, such as audio, video, and special effects. As modern attractions become increasingly sophisticated and complex, and expectations among guests of amusement and / or theme parks correspondingly increase, there is a need for improved and more original attractions, including attractions that provide a more interactive and personalized experience. Summary of the Invention [Means for solving the problem]

[0004] The following summarizes certain embodiments common in scope to the original claimed subject matter. These embodiments are not intended to limit the scope of the disclosure, but rather to provide a brief summary of some disclosed embodiments. Indeed, the disclosure may include a variety of forms that may be similar to or different from the embodiments set forth below.

[0005] In one embodiment, a wearable device includes a first radio frequency identification (RFID) tag, a second RFID tag, one or more feedback devices configured to provide feedback to a guest, and a microcontroller configured to generate a first control signal via the one or more feedback devices in response to an interaction between electromagnetic radiation having a first frequency and the first RFID tag, the first control signal causing a first type of feedback, and to generate a second control signal via the one or more feedback devices in response to an interaction between electromagnetic radiation having a second frequency and the second RFID tag, the second control signal causing a second type of feedback.

[0010] One or more specific embodiments of the present disclosure are described below. In order to describe these embodiments concisely, not all features of an actual implementation may be described herein. It should be understood that the development of any such actual implementation, as in any engineering or design project, requires numerous implementation-specific decisions to be made to achieve the developer's particular objectives, such as adhering to system-related and business-related constraints that may vary from implementation to implementation. Moreover, such a development effort may be complex and time-consuming, but should be understood to be a routine undertaking of design, fabrication and manufacture for those of ordinary skill in the art having the benefit of this disclosure.

[0011] Amusement parks feature a variety of entertainment, such as amusement rides, live shows, and games. The various types of entertainment may include features that enhance a guest's experience at the amusement park. For example, a game may detect a guest's interaction with a rendered image shown on a display screen. However, some interaction systems may provide a suboptimal experience due to a lack of feedback that notifies the guest that an interaction (e.g., as recognized by the interaction system) is successful. Furthermore, some interaction systems may not identify the identity of a guest who has interacted with an interactive element, and therefore may not accurately or efficiently track points or other game statistics for each guest. Thus, it may be desirable to provide a system and method that provides a guest with feedback indicating that an interaction has actually been detected by the interaction system, and / or tracks game statistics for each guest.

[0012] Accordingly, the present disclosure relates to systems and methods that utilize radio frequency identification (RFID) to provide feedback to guests based on their interaction with an interaction system. Specifically, the present disclosure relates to an interaction system that includes one or more RFID readers and a plurality of wearable devices, each having one or more RFID tags and one or more feedback devices (e.g., lights) that cooperate to indicate successful interaction with interactive elements of an attraction. Components of the interaction system disclosed herein can also facilitate tracking of guest interactions and progress (e.g., game statistics) as the guest moves through attractions.

[0013] The term "user" as used below may refer to a user of an interaction system, where the user may be a visitor of an amusement park. As an example, the user may wear or carry a wearable device having one or more feedback devices as he moves between attractions. The attractions may have various interaction elements, which may be any of a variety of images or objects (e.g., rendered images presented on a display screen, virtual or graphical elements, physical targets, costumed characters). The user may interact with the interaction elements, such as by touching a physical target or approaching a costumed character, to experience the attraction.

[0014] One or more RFID readers of the interaction system may be placed at various locations around the attraction and / or near some of the interactive elements. In operation, the one or more RFID readers communicate with one or more RFID tags in the user's wearable device. The communication between the one or more RFID readers and the one or more RFID tags may trigger a feedback response (e.g., turn on a light) via one or more feedback devices of the wearable device, thereby providing feedback to the user, for example, that the interaction system has detected the user in the attraction and / or the user's interaction with the interactive elements. The communication between the one or more RFID readers and the one or more RFID tags may also enable the interaction system to track the user's progress (e.g., game statistics) as the user moves through the attraction. For example, the interaction system may detect and keep track of the number of targets the user has come into contact with and / or the number of mascot characters the user has encountered.

[0015] Further, in one embodiment, the interaction system can provide feedback indicative of a user's status (e.g., level in a game) via one or more feedback devices on the wearable device. For example, upon reaching a certain number of points or a higher level in a game, one or more RFID readers can write data to one or more RFID tags in the wearable device that triggers a feedback response (e.g., turning on a number of lights) via one or more feedback devices. Thus, the interaction system can provide substantially instantaneous feedback when a user interacts with an interactive element of an attraction and / or when the user reaches a certain level (e.g., a milestone or achievement). Furthermore, the interaction system can enable a user to receive such feedback without having to refer to an external device, such as a mobile phone or kiosk, thereby providing a highly immersive and enjoyable experience.

[0016] Referring now to the drawings, FIG. 1 is a schematic diagram of an interaction system 10 including a reader system 12 (e.g., a radio frequency identification [RFID] reader system) and a wearable device 14. In one embodiment, the wearable device 14 is a wearable or portable device, such as a bracelet, necklace, jewelry, pin, or toy, that a user can wear or carry as they move between attractions. As described in more detail below, the reader system 12 can communicate with the wearable device 14 via electromagnetic radiation, which allows tracking of a user's progress as they move between attractions (e.g., number of rides completed, areas visited, interactive elements touched, mascot characters encountered, virtual achievements earned). This communication also allows the wearable device 14 to provide feedback to the user indicative of their progress and / or various interactions via feedback responses (e.g., light, sound, or haptics) that it outputs.

[0017] As shown in FIG. 1 , one embodiment of the reader system 12 includes a first reader 16 and a second reader 18 communicatively coupled to a computer system 20 (having a memory 54 and a processor 56) that accesses information stored in one or more databases 22 (e.g., a cloud-based storage system). In general, the first reader 16 and the second reader 18 transmit electromagnetic radiation (e.g., signals) to the wearable device 14. In one embodiment, the first reader 16 transmits a signal 24 at one frequency (e.g., range) and the second reader 18 transmits a signal 26 at another frequency (e.g., range) different from the first frequency. In addition to transmitting signals 24, 26, the first reader 16 and the second reader 18 can also receive signals, such as signals returned from the wearable device 14 and signals from the computer system 20. In one embodiment, the computer system 20 instructs the readers (e.g., the first reader 16 and the second reader 18) to transmit signals 24, 26 to the wearable device 14 based on information stored in the data encoded in one or more databases 22. It should be understood, therefore, that the first reader 16 and the second reader 18 can be transceivers capable of both transmitting and receiving signals.

[0018] As shown in Fig. 1, one embodiment of the wearable device 14 includes a first RFID tag 28, a second RFID tag 30, a microcontroller 32, one or more light emitting diodes (LEDs) 34a, 34b, 34c, 34d, and a power circuit 36 ​​that cooperate to enable the wearable device 14 of the interaction system 10 to function as disclosed. As shown, the wearable device 14 has four LEDs 34, but it should be understood that there may be fewer or more LEDs 34. Each of the first RFID tag 28 and the second RFID tag 30 includes an antenna 38 for transmitting and receiving signals, a memory 40 for storing information (e.g., a unique identification code), a microchip 42, and an integrated circuit 44 for powering the microchip 42. The integrated circuit 44 also powers the power circuit 36, which provides power to the microcontroller 32. In one embodiment, the power circuit 36 ​​may include an energy storage device (e.g., a capacitor, a supercapacitor, or a battery) configured to store power. As shown, the microcontroller 32 of the wearable device 14 includes a memory 46 and a processor 48. The memory 46 stores computer readable instructions that the processor 48 executes to control the operation of the microcontroller 32.

[0019] In general, the antenna 38 of the first RFID tag 28 is designed to receive the signal 24 from the first reader 16 of the reader system 12, and the antenna 28 of the second RFID tag 30 is designed to receive the signal 26 from the second reader 18. The microcontroller 32 identifies an interaction between the tag 28, 30 and the reader 16, 18 and transmits a signal (e.g., a control signal) to one or more of the LEDs 34 to provide feedback to the user. In one embodiment, the wearable device 14 of the interaction system 10 can include additional or alternative feedback devices, such as audio devices configured to emit sounds or haptics configured to provide tactile output (e.g., vibrations). Additionally or alternatively, the first RFID tag 28 and / or the second RFID tag 30 emit backscatter indicative of a unique identification code, which is utilized by the computer system to track the user's progress (e.g., game statistics) as the user moves between attractions.

[0020] Specifically, the first reader 16 of the reader system 12 continuously transmits a signal 24. The antenna 38 of the first RFID tag 28 is configured to receive electromagnetic radiation (e.g., signal 24) from the first reader 16 and transmit a signal 50 to the first reader 16. The integrated circuit 44 converts the electromagnetic radiation received by the antenna 38 into electricity to power the microchip 42, which generates a backscatter (e.g., signal 50). This backscatter includes information (e.g., a unique identification code) stored in the memory 40 of the first RFID tag 28. The first reader 16 can receive this backscatter (e.g., signal 50) and transmit a signal to the computer system 20. The computer system 20 may process this signal to determine the identity of the user associated with the wearable device 14 (e.g., a user may register the wearable device 14 prior to experiencing an attraction to associate the wearable device 14 with the user) and / or update information (e.g., game statistics) for the wearable device 14 in one or more databases 22. In this manner, the interaction system 10 may track the user's progress (e.g., game statistics) as the user moves from attraction to attraction.

[0021] Additionally, when the microcontroller 32 is powered, the processor 48 of the microcontroller 32 may also receive and process a signal from the first RFID tag 28 indicating that the signal 24 from the first reader 16 has been received at the first RFID tag 28. The processor 48 of the microcontroller 32 may then execute instructions stored in the memory 46 of the microcontroller 32 to illuminate one or more of the LEDs 34a, 34b, 34c, 34d to provide feedback to the user. In one embodiment, the microcontroller 32 may be programmed to provide a particular type of illumination (e.g., number of lights, color, blinking pattern, duration) in response to a signal indicating that the signal 24 from the first reader 16 has been received at the first RFID tag 28. For example, when the first RFID tag 28 receives the signal 24 from the first RFID reader 16, the microcontroller 32 may illuminate the first LED 34a. In one embodiment, the signal 24 transmitted by the first reader 16 is an ultra-high frequency (UHF) signal (e.g., having a frequency of about 300 megahertz to 3 gigahertz). Thus, the first RFID tag 28 can receive the signal 24 from the first reader 16 when located at a relatively long distance (e.g., up to about 3, 4, 5, 6, 7, 8 meters or more) from the first reader 16.

[0022] The second reader 18 may also continuously transmit a signal 26. The antenna 38 of the second RFID tag 30 is configured to receive electromagnetic radiation (e.g., signal 26) from the second reader 18. The integrated circuit 44 converts the radiation received by the antenna 38 into electricity to power the microchip 42, which generates a backscatter (e.g., signal 52) that includes information (e.g., a unique identification code) stored in the memory 40 of the second RFID tag 30. It should be appreciated that in some embodiments, the information stored in the respective memories 40 of the first and second RFID tags 28 and 30 may be linked (e.g., the backscatter generated in response to receiving the signal 26 at the second RFID tag 30 may include information stored in the memory 40 of the first RFID tag 28), or the first and second RFID tags 28 and 30 may share a single memory 40 (e.g., the tags may be a dual RFID tag capable of receiving different frequency signals). The second reader 18 may receive this backscatter (e.g., signal 52) and transmit a signal to the computer system 20. The computer system 20 may process this signal to determine the identity of the user associated with the wearable device 14 and / or update information (e.g., game statistics) for the wearable device 14 in one or more databases 22. A first RFID reader 16 can be associated with a particular area (e.g., a room) of the attraction and a second RFID reader 18 can be associated with a particular interactive element (e.g., a target) of the attraction, so that the computer system 20 can track both the user's general location and the user's interactions with the interactive elements. In this way, the interaction system 10 can track a user's progress (e.g., game statistics) as the user moves through the attraction.

[0023] Additionally, when the microcontroller 32 is powered, the processor 48 of the microcontroller 32 may also receive and process a signal from the second RFID tag 30 indicating that a signal 26 from the second reader 18 has been received at the second RFID tag 30. The processor 48 of the microcontroller 32 may then execute instructions stored in the memory 46 of the microcontroller 32 to illuminate one or more of the LEDs 34a, 34b, 34c, 34d to provide feedback to the user. In one embodiment, the microcontroller 32 may be programmed to provide a particular type of illumination (e.g., number of lights, color, blinking pattern, duration) in response to a signal indicating that a signal 26 from the second reader 18 has been received at the second RFID tag 30. For example, when the second RFID tag 30 receives the signal 26 from the second RFID reader 18, the microcontroller 32 may illuminate the first LED 34b. In one embodiment, the signal 26 transmitted by the second reader 16 is a Near Field Communication (NFC) signal (e.g., having a frequency of about 10-20 megahertz). Thus, the second RFID tag 30 can receive the signal 26 from the second reader 18 when located at a relatively short distance (e.g., about 1, 2, 3, 4, or 5 centimeters) from the first reader 16. Because the first RFID reader 16 can be associated with a particular area (e.g., a room) of the attraction and the second RFID reader 18 can be associated with a particular interactive element (e.g., a target) of the attraction, lighting (or other feedback, such as audio or haptics) on the wearable device 14 can provide multiple types of feedback to the user. For example, illumination of a first LED 34a in response to a signal 24 being received from a first RFID reader 16 may notify the user that the interaction system 10 has detected the user within a particular area of ​​the attraction, while illumination of a second LED 34b in response to a signal 26 being received from a second RFID reader 18 may notify the user that the interaction system 10 has detected an interaction of the user with a particular interaction element.

[0024] In general, the second reader 18 operates similarly to the first reader 16, except that the first reader 16 communicates with the first RFID tag 28 (and not with the second RFID tag 30) and the second reader 18 communicates with the second RFID tag 30 (and not with the first RFID tag 28). The wearable device 14 includes at least two RFID tags 28, 30 configured to communicate with respective readers 16, 18, each transmitting a signal 24, 26 that propagates over a different distance. The first RFID tag 28 and the first reader 16, which communicate over a relatively long distance, allow tracking of the coarse location of the wearable device 14 and charging of the wearable device 14, whereas the second RFID tag 30 and the second reader 18, which communicate over a relatively short distance, allow monitoring of interactions based on contact (or proximity) between the user and interactive elements in the attraction.

[0025] In one embodiment, the interaction system 10 may include multiple first readers 16 at different locations within the attraction. As the user moves between attractions, the user's location is updated in the database 22 based on which first reader 16 is currently in communication with the wearable device 14. In one embodiment, feedback may be provided to the user based on the respective interaction with each of the first readers 16. For example, one first reader 16 may be located at the entrance of the attraction and another first reader 16 may be located within a room or area of ​​the attraction. In this case, the wearable device 14 notifies the user that it has been detected by the interaction system 10 by providing feedback (e.g., illumination of the first LED 34a) when the user enters the attraction. Then, when the user enters the room or area, the wearable device 14 notifies the user that it has been detected by the interaction system 10 as being in the new area by providing another feedback (e.g., the same feedback or a different feedback such as illumination of the second LED 34b).

[0026] In one embodiment, one or more first readers 16 and one or more second readers 18 can cooperate to enhance a user's immersive experience. For example, a user can enter an area that includes one or more first readers 16. The area can include one or more targets, each associated with or proximate to one or more second readers 18. As described above, when the wearable device 14 comes within range (e.g., a relatively long range) of one first reader 16 in the area, the wearable device 14 can communicate with the one first reader 16, update the database 22, and provide feedback to the user that it has been detected within the area. Additionally, when the wearable device 14 comes within range (e.g., a relatively short range) of one of the second readers 18 (e.g., by the user reaching, touching, or walking by a target associated with the one of the second readers 18), the wearable device 14 can communicate with the one of the second readers 18, update the database 22, and provide feedback to the user that they have successfully interacted with the target (e.g., points have been assigned).

[0027] As discussed above, the microcontroller 32 may be programmed to provide some feedback to the user based on the interaction between the RFID tags 28, 30 of the wearable device 14 and the readers 16, 18. Additionally or alternatively, the memory 40 of the wearable device 14 may be updated (e.g., one or more of the readers 16, 18 may write to the memory 40 of one or more of the RFID tags 28, 30) to enable the wearable device 14 to provide other feedback, such as feedback indicating the user's progress (e.g., in-game level), wait time, etc. For example, upon detecting an initial interaction between the user and the second reader 18, the computer system 20 may instruct the first reader 16 to write data to the memory 40 of each of the first RFID tags 28 that (if received and processed by the microcontroller 32, for example) will cause the microcontroller 32 to illuminate the first LED 34a. On the other hand, if the computer system 20 determines (e.g., based on communication between the second RFID tag 30 associated with the target and the second reader 18) that the user has completed a predetermined number of successful interactions with the target, the computer system 20 can instruct the first reader 16 to write data to the memory 40 of each of the first RFID tags 28 that causes the microcontroller 32 to illuminate a number of LEDs (e.g., LEDs 34a-d or any combination thereof) and / or trigger a feedback response via the speaker or haptics. Thus, feedback is provided based on information stored in the database 22. For example, the database 22 can include information regarding the user's progress throughout the attraction based on the user's interactions with one or more of the first and second readers 16 and 18, and can provide feedback when certain conditions are met (e.g., levels or points are achieved). In this manner, the wearable device 14 can provide feedback indicative of the user's overall progress or achievements.

[0028] In one embodiment, a user may prompt or request feedback by entering a particular area (e.g., a status update area) having one or more first readers 16. Upon communication between one of these first readers 16 and a first RFID tag 28 of the wearable device 14, the computer system 20 may instruct the first readers 16 to write data to a respective memory 40 of the first RFID tag 28 to provide feedback indicative of the user's progress. In one embodiment, each time the first RFID tag 28 communicates with one first reader 16 and / or one second reader 18, the user may receive such feedback indicative of the user's progress. Thus, the user may be repeatedly updated regarding his or her progress as the user moves between attractions.

[0029] In one embodiment, the LEDs 34a-d can be used to indicate an indication of the wait time for the attraction. For example, when the computer system 20 detects that a user is approaching the attraction (e.g., based on communication between the first reader 16 and the first RFID tag 28 in proximity to the entrance of the attraction), it can instruct the first reader 16 to write data (e.g., when received and processed by the microcontroller 32) to light the LEDs 34a-d in a manner that communicates to the microcontroller 32 the wait time or whether a particular wait time threshold has been met. For example, at least one LED 34 can be multi-colored (e.g., configured to emit red, yellow, and green lights), with each color indicating an approximate wait time (e.g., a first color indicating a wait time of more than 15 minutes, a second color indicating a wait time of less than 5 minutes, and a third color indicating no wait time). Since multiple first readers 16 can be placed throughout the attraction or amusement park, the user can continue to receive feedback regarding the wait time even after moving out of range of the first reader 16 proximate the entrance of the attraction (e.g., because other first readers 16 can write data to the memory 40 of each of the first RFID tags 28). In one embodiment, each LED 34 can represent an approximate wait time (e.g., 5 minutes, 10 minutes, 15 minutes) such that the number of lit LEDs 34 is an indication of the wait time (e.g., 4 LEDs indicate a wait time of 60 minutes or more, 3 LEDs indicate a wait time of 45 minutes or more, 2 LEDs indicate a wait time of 30 minutes or more, and 1 LED indicates a wait time of 15 minutes or more). In one embodiment, the LEDs 34 can represent a countdown timer. For example, when it detects that the user is approaching the attraction, all the LEDs 34a-d are initially lit and then sequentially turned off as the countdown timer decreases.

[0030] As described above, in one embodiment, the antenna 38 of the first RFID tag 28 can only receive UHF waves, and the antenna 38 of the second RFID tag 30 can only receive NFC waves. For example, the first RFID tag 28 can only communicate (e.g., receive or transmit) using UHF waves, and the second RFID tag 30 can only communicate using NFC waves. Because UHF signals propagate over longer distances, the first RFID tag 28 can frequently or continuously receive UHF signals emitted by the first reader 16 as the user moves between attractions, but the second RFID tag 30 can only receive NFC signals emitted by the second reader 18 when the user places the wearable device 14 in proximity to the second reader 18. Thus, in one embodiment, the UHF signals can be used to power or charge the wearable device 14 (e.g., via power harvesting by the integrated circuit 44 and the power circuit 36). However, the NFC signal can also be used to power or charge the wearable device 14.

[0031] It should be appreciated that the interaction system 10 can track multiple users and provide feedback to multiple wearable devices 14. For example, each of the multiple users can wear a respective wearable device 14 configured to communicate with multiple first and second readers 16, 18 located at different locations within the attraction. It should also be appreciated that in one embodiment, the wearable device 14 of the interaction system 10 can include a single RFID tag (e.g., a dual frequency RFID tag) capable of communicating with signals at a first frequency (e.g., a range of frequencies) and signals at a second frequency (e.g., another range of frequencies) to facilitate the techniques disclosed herein.

[0032] 2 is a diagram of one embodiment of an interaction system 10. As shown, the interaction system 10 includes two first readers 16a and 16b, a second reader 18 located in or proximate to a target 58, and a wearable device 14 worn by a user 60. The first readers 16a and 16b and the second reader 18 are communicatively coupled to a computer system 20 and a database 22. The first reader 16a continuously emits a signal 24a that can be received by a first RFID tag 28 of the wearable device 14 within a first area 62a (e.g., a zone or room of an attraction), and similarly the first reader 16b continuously emits a signal 24b that can be received by a first RFID tag 28 of the wearable device 14 when the user 60 enters a second area 62b. Thus, the wearable device 14 can communicate (e.g., receive signals / electromagnetic radiation, backscatter information) with either or both of the first reader 16a in the first area 62a or the first reader 16b in the second area 62b depending on the location of the user 60. The computer system 20 determines the location of the user 60 based on which first reader (e.g., 16a or 16b) communicates with the wearable device 14 and updates the database 22 with data indicative of the location of the user 60. Also, when the wearable device 14 of the user 60 communicates with the first reader 16a or the first reader 16b, power is harvested and provided to the microcontroller 32. Thus, the microcontroller 32 starts processing signals received from the first RFID tag 28 and / or reading data written in the memory 40 of the first RFID tag 28. For example, the microcontroller 32 may receive a signal from the first RFID tag 28 indicating that the first RFID tag 28 has communicated with one of the first readers 16 and provide a corresponding feedback response (e.g., illuminate one or more LEDs). As described above, the first RFID tag 28 may receive a signal from the first reader 16 that writes data to the memory 40 of the first RFID tag 28, causing the microcontroller 32 to provide a particular feedback response.

[0033] As shown in FIG. 2, the second reader 18 is placed in or proximate to the target 58. The target 58 can be any of a variety of objects or features within the attraction. In one embodiment, the target 58 is a stationary object, but the target 58 can also be a virtual object (e.g., an image, virtual element, graphic element on a display screen) or a movable object such as a mascot character that moves around the attraction. The second reader 18 emits a signal 26 that can be received within the area 64. In operation, when a user 60 brings the wearable device 14 into the area 64, the wearable device 14 communicates with the second reader 18. As a result, the second RFID tag 30 of the wearable device 14 emits a backscatter that includes information identifying the user. The second reader 18 transmits this information to the computer system 20 to indicate that the user 60 has been detected by the second reader 18 and has therefore interacted with the target 58. Additionally, the microcontroller 32 can receive a signal from the second RFID tag 30 indicating that the second RFID tag 30 has communicated with the second reader 18 and provide a corresponding feedback response (e.g., by lighting one or more LEDs).

[0034] It should be understood that the microcontroller 32 can be configured to generate a first control signal that causes a first feedback response in response to receiving a signal from the first RFID tag 28 indicating that the first RFID tag 28 has communicated with one of the first readers 16, generate a second control signal that causes a second feedback response in response to receiving a signal from the second RFID tag 30 indicating that the second RFID tag 30 has communicated with the second reader 18, and generate a third control signal that causes a third feedback response in response to receiving a signal indicating that both the first RFID tag 28 and the second RFID tag 30 have communicated with their respective readers (i.e., the first reader 16 and the second reader 18). The first, second and third feedback responses may be different types of feedback responses, such as a type of lighting (e.g., number of lights, color, blinking pattern, length of time), a type of sound (e.g., volume, tone, beep pattern, length of time), or a type of touch (e.g., intensity, length of time).

[0035] The user 60 may not be in either area 62a or 62b during a period of time and therefore may not receive the signal 24a or 24b from the first reader 16a or 16b. In one embodiment, the wearable device 14 may continue to provide power (e.g., for 5, 15, 30, 60 or more seconds) using power stored in the power circuit 36 ​​even while the wearable device 14 is outside the areas 62a and 62b. Thus, the wearable device 14 may provide feedback (e.g., illuminate an LED to indicate progress or wait time, etc.) even while the user is outside the areas 62a and 62b, thereby increasing the time for the user to notice the feedback response. In one embodiment, the feedback response (e.g., illuminate the LED) may be stopped if the user 60 leaves the area 62a defined by the signal 24a emitted from the first reader 16a.

[0036] 3 is a diagram of one embodiment of an interaction system 10 including a first user 60a, a second user 60b, a second reader 18 located in or proximate to a target 58, and a first reader 16. The second reader 18 and the first reader 16 are communicatively coupled to a computer system 20 and a database 22. The second reader 18 also emits a signal 26 throughout an area 64. The first user 60a wears a first wearable device 14a including one or more LEDs 34, and the second user 60b wears a second wearable device 14b including one or more LEDs 34. In one embodiment, the second reader 18 has a relatively short communication range and thus communicates with the wearable device 14 when the user physically contacts the target 58 including the second reader 18 or when the wearable device 14 is otherwise brought into the area 64. Furthermore, the first reader 16 has a relatively long communication range and is therefore in constant communication with the wearable devices 14a and 14b via electromagnetic radiation.

[0037] In operation, when a first user 60a contacts (e.g., touches or reaches) a target 58 that includes a second reader 18, the wearable device 14 provides feedback 66 through illumination of one or more LEDs 34. Specifically, when the first user 60a contacts the second reader 18, the first wearable device 14a (specifically, the second RFID tag 30 of the first wearable device 14a) is brought within range of the second reader 18. The second user 60b is at a distance 68 outside the range of the second reader 18 and therefore does not receive feedback from the one or more LEDs 34 of the second wearable device 14b. In some embodiments, both the first user 60a and the second user 60b may be within range of the second reader 18 (e.g., by contacting the target 58 at the same time). In such a case, the LEDs 34 of both the first wearable device 14 and the second wearable device 14b provide suitable feedback.

[0038] FIG. 4 illustrates an embodiment of an interaction system 10 showing team feedback (e.g., feedback to multiple users designated or assigned to a team). As shown in FIG. 4, there is a first user 60a, a second user 60b, a third user 60c, a second reader 18, and a first reader 16. The second reader 18 and the first reader 16 are electronically coupled to a computer system 20 and a database 22. The first user 60a, the second user 60b, and the third user 60c have a first wearable device 14a, a second wearable device 14b, and a third wearable device 14c, respectively, each having one or more LEDs 34. The first user 60a and the third user 60c are part of a team and therefore may wear a team indicator 70 that distinguishes the first user 60a and the third user 60c from the second user 60b. In one embodiment, the team indicators can be physical characteristics (e.g., color, shape, pattern) of the wearable device 14. In one embodiment, the computer system 20 can form or determine the teams based on information stored in the database 22 (e.g., family members or other users connected by characteristics such as last name, age, groups entering the attraction at the same time, game level, etc., characteristics of the wearable device 14, team selection or assignment requests entered by users). Thus, the first user 60a and the third user 60c belong to a first team (e.g., team A) and the second user belongs to a second team (e.g., team B).

[0039] As shown in FIG. 4, the first wearable device 14a worn by the first user 60a is present in the area 64 and interacts with the signal 26 emitted by the second reader 18. As described above, the second reader 18 receives information from the memory 40 of the second RFID tag 30 of the first wearable device 14a by backscattering. This information is transmitted to the computer system 20, which identifies the first user 60a based on this information. The computer system 20 also determines that the first user 60a belongs to team A based on the information stored in the database 22. As a result, the computer system 20 transmits a signal (e.g., a control signal) to the first reader 16 to transmit electromagnetic radiation to the wearable devices 14a, 14c of the first and third users 60a, 60c to write data to the memory 40 of the respective first RFID tags 28. The respective microcontroller 32 of each of the wearable devices 14a, 14c reads the data written to the memory 40 of the respective first RFID tag 28. The updated memory 40 contains data that, when read by the microcontroller 32, causes the microcontroller 32 to initiate a particular feedback response.

[0040] As shown, the feedback response is provided via illumination of the LEDs 34 of the first wearable device 14a and the third wearable device 14c. Thus, once one user (e.g., the first user 60a) interacts with the target 58, all users belonging to the team can receive feedback due to this interaction. In one embodiment, all first readers 16 can be communicatively coupled to the computer system 20, so that users of the same team can receive feedback even if they are in different areas (e.g., not receiving signals from the same first reader 16). In one embodiment, feedback is provided only to users who receive signals 24 from the same reader 16. In one embodiment, all users of the same team receive feedback regardless of which first reader 16 they receive signals 24 from.

[0041] FIG. 5 is a diagram of a wearable device 14 according to an embodiment of the present technology. Although the wearable device 14 is shown having a lanyard 71 (e.g., a rope or string) coupled to a housing 73, it should be understood that the wearable device 14 can have any suitable form. For example, the wearable device 14 can include a strap (e.g., for fastening the housing 73 to a user's wrist) or can be an ornament or a toy carried by a user. As shown, the wearable device 14 includes a first LED display 72, a second LED display 74, an audio device 76 (e.g., a speaker), and haptics 78 (e.g., a vibration device). Any combination of the LEDs 34, haptics 78, audio device 76, or other feedback devices can also be activated to provide feedback to the user. It should be understood that the wearable device 14 can include only one of these feedback devices or any combination of these feedback devices.

[0042] As shown, the wearable device 14 can include multiple LED displays (e.g., a first LED display 72 and a second LED display 74), each of which can provide different types of feedback. For example, the first LED display 72 can provide feedback indicative of interaction with one or more first readers 16 and / or one or more second readers 18, while the second LED display 72 can provide feedback indicative of the wait time for an attraction. As shown in FIG. 5, the first LED display 72 and the second LED display 74 each include three LEDs (34a-c and 34d-f, respectively). In one embodiment, the wearable device 14 can include any number of LED displays including any number of LEDs (e.g., one, two, or more LED displays including one or more LEDs). In one embodiment, a single LED display (e.g., LED display 72) can provide some or all of the different types of feedback disclosed herein.

[0043] 6 is a flow diagram illustrating one embodiment of a process 80 for operating a wearable device 14 in accordance with the present technology. It should be understood that the steps described herein are merely exemplary and that some steps may be omitted or added, or steps may be performed in a different order. In one embodiment, the process 80 may be performed by the first RFID tag 28 and / or the second RFID tag 30 in cooperation with the microcontroller 32 of the wearable device 14.

[0044] The process 80 begins with the antenna 38 of the first RFID tag 28 and / or the second RFID tag 30 receiving electromagnetic radiation from the respective first reader 16 or second reader 18 (block 82). As described above, after receiving the electromagnetic radiation, the antenna 38 returns backscatter to the respective reader 16, 18, including information stored in the memory 40 of the RFID tag 28, 30. In one embodiment, this information may include an identification number unique to the wearable device 14 and thus identifying the user (e.g., the user using the wearable device 14). In one embodiment, the electromagnetic radiation emitted by the first reader 16 propagates a relatively long distance and the electromagnetic radiation emitted by the second reader 18 propagates a relatively short distance. The first RFID tag 28 may communicate with the first reader 16 and the second RFID tag 30 may communicate with the second reader 18.

[0045] When the wearable device 14 receives the electromagnetic radiation, it harvests power from the electromagnetic radiation (block 84). As described above, the first RFID tag 28 and the second RFID tag 30 may each include an integrated circuit 44 that powers the microchip 42. The integrated circuit 44 also powers the power circuit 36, which provides power to the microcontroller 32 (block 86) and other components of the wearable device (e.g., feedback device). In one embodiment, the power circuit 36 ​​may include an energy storage device (e.g., a capacitor, supercapacitor, or battery) electrically coupled to the receiving coil to store power when the wearable device 14 receives a signal from the first reader 16 and / or the second reader 18.

[0046] Once the microcontroller 32 is powered, the processor 48 executes (block 88) commands stored in the memory 46 to receive and / or process signals from the first RFID tag 28 and / or the second RFID tag 30. In one embodiment, the microcontroller 32 may be programmed to continuously or periodically interrogate the first RFID tag 28 and / or the second RFID tag 30 when powered.

[0047] Microcontroller 32 then outputs a signal (e.g., a control signal) to one or more feedback devices (block 90). In one embodiment, the control signal can cause activation of one or more of LEDs 34 and / or other feedback devices (e.g., audio devices, haptics). In one embodiment, the control signal is a variable voltage applied to one LED 34 to vary the intensity of the LED 34. In one embodiment, the signal is an oscillating voltage signal that causes the LED 34 to blink.

[0048] The feedback devices (e.g., LEDs, haptics, audio devices) provide a feedback response to the user (block 92). The feedback response may be provided in response to an interaction between the wearable device 14 and a reader system 12 located within the attraction. For example, the feedback response may include lighting one LED 34 to inform the user that they have entered the zone of the first reader 16 (e.g., their wearable device 14 is successfully communicating with the first reader 16) or that they have successfully interacted with an interactive element such as the target 58.

[0049] As described above, the first reader 16 and / or the second reader 18 can write to the memory 40 of the first RFID tag 28 and / or the second RFID tag 30. Thus, the user can receive a feedback response upon accomplishing a goal based on information tracked in the database 22 (e.g., leveling up, reaching a high score). In one embodiment, the feedback response can occur by different users successfully accomplishing a goal (e.g., when the users belong to the same team). In one embodiment, the feedback response can include one or more LEDs 34 indicating a time (e.g., a waiting time or time remaining in an area of ​​the attraction). In one embodiment, the feedback response can include a sound from an audio device 76 of the wearable device 14 indicating that the user needs to take an action (e.g., start a race, move to the next zone, join a game, etc.). In one embodiment, the volume from the audio device 76, the intensity of the LED lighting, or the intensity of the haptics 78 can be increased to indicate progress toward a goal in the attraction, for example.

[0050] Accordingly, the present disclosure relates to an interaction system having a reader system and a wearable device, in which the wearable device issues a feedback response based on communication between an RFID tag of the wearable device and a reader of the reader system. Specifically, the reader system includes readers (e.g., one or more first readers 16 and one or more second readers 18) that communicate (e.g., send and receive signals) with a first RFID and a second RFID of the wearable device through electromagnetic radiation during operation. The readers continuously emit electromagnetic radiation within a range (e.g., a communication range) and communicate with the wearable device when the wearable device enters the range. For example, one reader (e.g., a first reader) can have a communication range that is greater than the communication range of another reader (e.g., a second reader). Thus, the first reader generally communicates with the first RFID of the wearable device more frequently than the second reader communicates with the second RFID and / or at a different time than such communication. Readers that communicate periodically or over long periods of time with RFID tags may be better suited to power a power harvesting device and thus allow for the inclusion of feedback devices (e.g., audio devices, haptics, one or more LEDs) in wearable devices that may require more power to operate. In one embodiment, an RFID reader is placed within a stationary target that guests can interact with (e.g., touch or reach). In one embodiment, an RFID reader is placed within a moving target (e.g., within a character costume in an amusement park). Although the embodiments disclosed herein include two RFID readers with two different communication ranges, it should be understood that the system may include any number of readers (e.g., 1, 2, 3, 4, 5, 6 or more readers) configured to have any number of different communication ranges (e.g., 1, 2, 3, 4, 5, 6 or more different communication ranges). Additionally, the wearable device may include any number of RFID tags (e.g., 1, 2, 3, 4, 5, 6 or more RFID tags) configured to communicate with various readers to provide the functionality disclosed herein.

[0051] Although only certain features of the present disclosure have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is therefore to be understood that the appended claims are intended to cover all such modifications and changes that comply with the true spirit of the present disclosure. It is to be understood that any of the features illustrated or described with respect to Figures 1-6 may be combined in any suitable manner.
