[0002] FIELD OF THE DISCLOSURE The present disclosure relates generally to the field of amusement parks. Specifically, embodiments of the disclosure relate to techniques for controlling interactive devices within attractions. [Background technology]

[0003] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, as described below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. As such, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

[0004] Amusement parks have grown significantly in popularity since the early 20th century. To maintain this growing popularity, new amusement park attractions are designed to provide guests with unique immersive experiences. Some amusement park attractions allow for personal interaction with the amusement park attraction, enhancing the guest's immersive experience. However, the functionality of the devices used to interact with the amusement park attraction can interfere with the immersive experience of these personal interactions. For example, perceptible electronic devices (e.g., cell phones, controllers, battery-powered devices) can include features that are accessed by guest input, which can reduce the guest's immersion in the amusement park attraction's themed environment. Therefore, it can now be recognized that improvements to these amusement park attractions are desirable. Summary of the Invention [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0011]

[0013] One or more specific embodiments of the present disclosure will now be described. In the interest of brevity in describing these embodiments, not all features of an implementation may be described herein. It will be understood that the development of any such implementation, as in any engineering or design project, requires numerous implementation-specific decisions to be made to achieve the developer's particular objectives, including compliance with system- and business-related constraints that may vary from implementation to implementation. Moreover, it will be understood that such a development effort may be complex and time-consuming, but would be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill in the art having the benefit of this disclosure.

[0012] When introducing elements of various embodiments of the present disclosure, the articles "a," "an," and "the" are intended to mean the presence of one or more of the element. The terms "comprising," "including," and "having" are intended to be inclusive and mean that there may be additional elements other than the listed elements. Furthermore, references to "one embodiment" or "an embodiment" of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also contain the recited features.

[0013] Theme park or amusement park attractions have become increasingly popular, resulting in the creation of a variety of amusement park attractions that offer passengers unique immersive experiences. Some amusement park attractions enhance the guest's immersive experience by allowing guests to interact with the attraction via a guest-related device, such as a wireless device. For example, guests may access software applications on their mobile devices to obtain more information about a particular attraction. However, guest interaction with a mobile device tends to distract the guest from the attraction. For example, some attractions may have rustic or historic attraction environments, and mobile devices do not fit the context of such environments. Also, more tech-savvy guests may be distracted by the ability to access complex functions via a mobile device. Furthermore, not all attractions allow guests to hold onto their mobile devices during the attraction.

[0014] Provided herein are wirelessly operated wirelessly powered guest devices configured with dedicated functionality to operate with one or more attractions in an amusement park. In some embodiments, this functionality can be activated automatically at appropriate times within the attraction or upon specific guest interaction with the attraction, such as when the guest must operate or provide user input to activate the functionality of the guest device. In this manner, the guest's attention is not drawn away from the attraction. Such devices can be relatively simple to reduce cost and / or weight. For example, these devices can be powered by energy captured by a wireless transmitter without the added weight of a battery. Furthermore, components of the wirelessly powered devices can be housed in various themed devices (e.g., amulets, rings, bracelets, torches, wands, teddy bears, etc.) to allow guests to interact with the amusement park attractions using the themed devices. To enhance the immersive experience, the wirelessly powered devices can be configured to interact with not only the amusement park attractions but also other wirelessly powered devices.

[0015] FIG. 1 is a perspective view of an embodiment of a wireless power system 10 for an amusement park attraction 12. The wireless power system 10 can be positioned to provide wireless power to guest devices 14 located within an environment 16 of the amusement park attraction 12 (e.g., a portion of a ride track, a room, etc.). In some embodiments, the wireless power system 10 is configured to provide wireless power to guest devices 14 (e.g., wirelessly powered devices) throughout the amusement park attraction 12 and / or throughout the amusement park. The wireless power system 10 includes a control system 18 having an emitter 20 configured to output radio waves 22 into the environment 16. The radio waves 22 provide wireless power to the guest devices 14. The control system 18 can also include communication circuitry 24 (e.g., a transceiver 32) configured to send communication signals 26 to the guest devices 14. The communication circuitry 24 can also be configured to receive communication signals from the guest devices 14 via a detector 28 in the communication circuitry 24.

[0016] In the illustrated embodiment, the environment 16 includes multiple emitters 20 and communication circuitry 24 to improve power dissipation and communication between the control system 18 and the guest devices 14. As described above, the transceivers of the communication circuitry 24 can be configured to output communication signals 26 (e.g., control system signals 30). The control system signals 30 can be infrared signals. Placing multiple transceivers 32 at various orientations around the environment 16 can improve communication between the control system 18 and the guest devices 14 when using infrared signals by ensuring that the guest devices 14 remain within range or line of sight of at least one of the multiple transceivers 32.

[0017] Guest devices 14 may be provided to guests at the amusement park attraction 12. The guest devices 14 may be themed devices specific to the theme of the amusement park attraction 12. For example, in an amusement park attraction themed around underground treasure hunting, the guest devices 14 may have the shape of a torch. When a guest moves the guest device 14 (e.g., the torch) near a thematic heat source in the environment 16 (e.g., a campfire special effect), the control system 18 may output a control system signal 30 that causes the guest device 14 (e.g., the torch) to light. In some embodiments, each guest may have a different guest device 14. For example, a first guest device 34 may be a charm and a second guest device 36 may be a bracelet.

[0018] 2 is a block diagram of an embodiment of a control system 18 and a guest device 14 of the wireless power system 10. The control system 18 is configured to provide wireless power to the guest device 14. Additionally, the control system 18 is configured to communicate with the guest device 14. The control system 18 may include communications circuitry 24, such as an antenna, wireless transceiver circuitry, and signal processing hardware and / or software (e.g., hardware or software filters, A / D converters, multiplexers, amplifiers), or a combination thereof, and may be configured to communicate over a wireless communications path via infrared (IR) wireless communications, satellite communications, broadcast radio, microwave radio, Bluetooth, Zigbee, Wi-Fi, UHF, NFC, etc. In one embodiment, the communications circuitry 24 includes multiple IR transceivers disposed within the environment of the amusement park attraction.

[0019] The control system 18 may include a system processor 38 and a memory 40. The system processor 38 may include one or more processing devices, and the memory 40 may include one or more tangible, non-transitory machine-readable media. By way of example, such machine-readable media may include RAM, ROM, EPROM, EEPROM, optical disk storage, magnetic disk storage, or other magnetic storage devices, or any other medium that can be used to hold or store desired program code in the form of machine-executable instructions or data structures and that can be accessed by the system processor 38 or other processor-based device (e.g., a mobile device). In some embodiments, the memory 40 is configured to store instructions executable by the system processor 38 to output various control system signals 30. For example, the system processor 38 may execute instructions to output a control system signal 30 that activates an indicator 42 on the first guest device 34 based on communications from the first guest device 34, other guest devices 14, and / or data from a timer, an attraction event schedule, etc.

[0020] The control system 18 can include an emitter 44. The emitter 44 is configured to output radio waves 22 that provide wireless power to the environment 16. In some embodiments, the radio waves 22 are ultra-high frequency radio frequency identification waves (UHF RFID). However, any type of suitable radio waves 22 can be emitted to provide wireless power to the environment. In some embodiments, the control system 18 can have multiple emitters 44.

[0021] The guest device 14 is configured to receive power from the control system 18 via its respective energy-harvesting element 46 (e.g., first energy-harvesting element 66, second energy-harvesting element 68, etc.). The energy-harvesting element 46 is configured to receive radio waves 22 emitted from an emitter 44 of the control system 18 via an antenna 124 (e.g., first antenna 127, second antenna 129, etc.) and harvest energy from the radio waves 22. In some embodiments, the energy harvested from the radio waves 22 is output directly to components of the guest device 14 (e.g., sensor 48, processor 52, transmitter 56, etc.). Meanwhile, in some embodiments, the guest device 14 includes a capacitor 60 (e.g., first capacitor 62, second capacitor 64, etc.) configured to receive energy from the energy-harvesting element 46 before outputting the energy to the components of the guest device 14. However, the guest device 14 does not have a battery configured to store energy from the energy-harvesting element 46. Additionally, the guest device 14 does not have a battery, and therefore none of the components of the guest device 14 are battery powered, nor is the guest device 14 powered by a wired connection.

[0022] The guest device 14 has a sensor 48 (e.g., a first sensor 50, a second sensor 54, etc.) configured to detect a state of the guest device 14. The sensor 48 can be configured to output a state signal 80 based on the detected state of the guest device 14. In some embodiments, the sensor 48 is a position sensor configured to detect a position of the guest device 14. The position sensor can be configured to output the position of the guest device 14 via the state signal 80. In other embodiments, the sensor 48 can be an accelerometer, a gyroscope, a pressure sensor, an optical sensor, an acoustic sensor, an infrared sensor, or some combination thereof.

[0023] The guest device 14 may include a processor 52 (e.g., a first processor 72, a second processor 74, etc.) configured to receive the status signals 80 from the sensors 48. The processor 52 may be configured to generate and output device control signals 82 (e.g., a first device control signal 84, a second device control signal 86, etc.) based on the status signals 80 and / or other inputs. The processor 52 may be a microprocessor. In some embodiments, the guest device 14 is configured to operate without a memory device. In other embodiments, the guest device 14 includes a memory device that stores instructions executable by the processor 52 of the guest device 14 to output various device control signals 82.

[0024] Guest device 14 may include communications circuitry with transmitters 56 (e.g., first transmitter 76, second transmitter 78, etc.) configured to receive device control signals 82 from processor 52 and provide outputs 88 to control system 18 and / or other guest devices 14 based on the guest device's status and / or other inputs. In some embodiments, transmitter 56 includes a long-range transmitter and / or a short-range transmitter. In other embodiments, transmitter 56 includes a medium-range transmitter.

[0025] In some embodiments, the transmitter 56 (e.g., first transmitter 76, second transmitter 78, etc.) includes an infrared emitting diode configured to output an infrared signal to a detector of the control system 18. The infrared signal is configured to transmit information between the guest device 14 and the control system 18. In some embodiments, the infrared signal output from the guest device 18 is configured to transmit information to other guest devices 14. The transmitter 56 can be configured to receive communications via infrared signals such that it can receive communications via infrared signals from the control system 18 and / or other guest devices 14.

[0026] In some embodiments, the control system 18 is configured to emit infrared light into the environment 16. The transmitter 56 can be configured to transmit information to the control system 18 and / or other guest devices 14 using an electrically switchable reflector. The electrically switchable reflector can be configured to selectively reflect the infrared light emitted from the control system 18 into the environment. The electrically switchable reflector can selectively reflect the infrared light in a pattern or sequence configured to transmit information from the guest device 14. The control system 18 and / or other guest devices 14 can be configured to receive the selectively reflected infrared light and identify information from the guest device 14 based on the pattern or sequence. The electrically switchable reflector can have a reflective surface configured to rotate to control the angle of reflection of the infrared light to generate the pattern or sequence.

[0027] In some embodiments, the transmitter 56 is configured to selectively filter the infrared signal to generate a filtered infrared signal and reflect the filtered infrared signal to a detector in the control system 18. The filtered infrared signal can be configured to transmit information from the guest device 14 to the control system 18 and / or other guest devices 14. In another embodiment, the transmitter 56 includes a reflective surface and an occluding device configured to selectively block one or more portions of the reflective surface to form a reflective pattern configured to reflect infrared light to the control system 18 and / or other guest devices 14. For example, the occluding device can cover a reflective surface having four reflective portions arranged in a 2x2 grid. The occluding device can block the top left reflective portion, leaving only the other three reflective portions to reflect infrared light. Selectively covering different portions of the reflective surface using the occluding device can convey different information. The transmitter 56 can be configured to transmit information from the guest device 14 to the control system 18 and / or other guest devices 14 via the occluding device selectively covering different portions of the reflective surface.

[0028] In some embodiments, at least the first energy harvesting element 66, the first processor 72, the first sensor 50, and the first transmitter 76 are all contained within a first housing 90 of the first guest device 34. Similarly, at least the second energy harvesting element 68, the second processor 74, the second sensor 54, and the second transmitter 78 are all contained within a second housing 92 of the second guest device 36.

[0029] FIG. 3 is a flow diagram of an embodiment of communication between the control system 18 and the guest device(s) 14. The control system 18 is configured to store instructions that, when executed, cause the control system 18 to output a control system signal 30. The control system 18 may be configured to execute the instructions based on a timer or an attraction event. For example, an amusement park attraction may be configured to generate a special effect (e.g., a gust of wind) at a predetermined time. The control system 18 may be configured to output a control system signal 30 configured to extinguish a guest device 14 (e.g., a torch) (e.g., turn off indicator 42) in response to the special effect (e.g., a gust of wind). In another embodiment, the control system 18 is configured to receive a communication from the guest device(s) 14 (block 128). The control system is configured to identify a control system signal 130 from instructions to be executed based on the communication received from the guest device(s) 14 (block 130). These instructions cause the control system to output a control system signal 30 (block 132). The control system signal 30 may be configured to light a guest device 14 (e.g., a torch). The control system 18 may include multiple instructions, each configured to execute based on a different condition or trigger (e.g., a timer, a vehicle event, a received communication, etc.).

[0030] The first guest device 34 may be configured to receive a control system signal 30 from the control system 18 (block 134). The first processor is configured to generate a first device control signal 84 in response to receiving the control system signal 30 (block 136). In some embodiments, the first processor is configured to generate the device control signal 84 based on both the control system signal 30 and a first status signal 80 from the first sensor 48. The first sensor may detect a status of the first guest device (block 138) and output a first status signal to the first processor indicating the status of the first guest device. The first processor is configured to receive the status signal from the first sensor (block 140). For example, the control system 18 may output a control system signal 30 configured to light up the first guest device 34. However, the first guest device 34 (e.g., a torch) may be located, or have recently been located, in a thematic water source that "wetted" or caused the first guest device 34 to become wet. The first processor may determine that the first guest device 34 (e.g., a torch) is "wet" and therefore cannot light, and may send a first device control signal 84 that causes the first guest device 34 to light up temporarily and then turn off or remain off, based on both the control system signal 30 and the status signal 80. In another example, a guest may quickly pass the first guest device 34 (e.g., a torch) through a thematic heat source. Although the control system signal 30 is configured to light the first guest device 34 (e.g., a torch) when the first guest device 34 (e.g., a torch) is located near the thematic heat source, the first processor may determine that the first guest device 34 (e.g., a torch) cannot light based on the velocity of the first guest device 34 from the status signal 80.

[0031] In some embodiments, the first guest device 34 is configured to output a status signal 80 from the first sensor 50 to the control system 18 (block 142). As described above, the status signal 80 can cause the control system 18 to execute various commands. The control system 18 can be configured to output a control system signal 30 when the first guest device 34 is located in a particular area of ​​the environment 16 of the amusement attraction 12 (e.g., near a thematic heat source). The control system 18 can also be configured to output a control system signal 30 based on other conditions (e.g., position, movement, etc.) of the first guest device 34. The control system 18 can be configured to output a control system signal 30 based on the position, acceleration, velocity, pressure, temperature, acoustics, logic state, etc. of the first guest device 34.

[0032] The first processor 72 may be configured to output a first device control signal 84 that modifies a first indicator 94 of the first guest device 34 (block 144). The first device control signal 84 may deactivate the first indicator 94 (block 146), activate the first indicator 94 (block 148), or adjust a setting of the first indicator 94 (block 150). For example, the first indicator 94 may be an LED light, where deactivating the first indicator 94 turns the LED light off, activating the first indicator 94 turns the LED light on, and adjusting the setting of the first indicator 94 may cause the LED to dim, brighten, or change color.

[0033] The first processor may be configured to output a first device control signal 84 to a first transmitter of the first guest device 34. The first transmitter may be configured to output a secondary signal 98 in response to receiving the first device control signal 84 (block 152). The secondary signal 98 may be configured to relay information from the first control system signal 84 to another guest device 14 (e.g., a second guest device 36). The second guest device 36 may be configured to receive the secondary signal 98 (block 154) and activate a second indicator 96 of the second guest device 36 based on the secondary signal 98. For example, the first guest device 34 and the second guest device 36 may be torches. As described above, the first guest device 34 (e.g., the torch) may light up based on the control system signal 30 when located near a thematic heat source (e.g., a campfire). The first guest device 34 can then be configured to output a secondary signal 98 that causes the first guest device 34 to light a second guest device 36 (e.g., a torch) when the second guest device 36 moves into close proximity to the first guest device 34, thereby creating the special effect of a torch lighting another torch.

[0034] In some embodiments, a second processor of a second guest device 36, similar to the first processor 72 of the first guest device 34, may generate a second device control signal 86 (block 156) based on both the secondary signal 98 detected from the second sensor 54 (block 158) and received by the second processor (block 160) and the second status signal 102. The second device control signal 86 may modify a second indicator 96 of the first guest device 34 (block 162). The second device control signal 84 may deactivate the first indicator 94 (block 164), activate the first indicator 94 (block 166), or adjust a setting of the first indicator 94 (block 168). The second guest device 36 may also be configured to output a tertiary signal 100 via a second transmitter such that the second guest device 36 (e.g., a torch) may light a third guest device (e.g., a torch) (block 170). Additionally, the second guest device 36 may be configured to output a second status signal 102 from the second sensor 54 to the control system 18 (block 172).

[0035] In some embodiments, the control system 18 can be configured to output a control system signal 30 based on the states of the plurality of guest devices 14. Additionally, the control system 18 can be configured to communicate with a special effects device of the amusement park attraction 12. For example, a first guest having a first guest device 34 and a second guest having a second guest device 36 can stand near a special effects device 126 (e.g., a trap door) within the environment of the amusement park attraction. The trap door can be configured to open when at least two guests are positioned near the trap door. The first and second guest devices 34, 36 can output their respective states (e.g., the locations of the guest devices) to the control system 18. The control system 18 can be configured to output a first control system signal 104 to the special effects device 126, causing the special effects device 126 (e.g., the trap door) to open. In some embodiments, when the trapdoor opens, a special effect event (e.g., a gust of wind) can occur, and the control system 18 can therefore output a second control system signal 106 to the first and / or second guest devices 34, 36, causing the guest devices to deactivate their respective indicators 94, 96 and "turn off" the guest devices 34, 36 (e.g., torches). In some embodiments, the control system 18 outputs a control system signal 30 to all guest devices 14 in the environment 16, causing all guest devices 14 to simultaneously deactivate their respective indicators. Meanwhile, in some embodiments, the control system 14 is configured to output the control system signal 30 to the guest device 14 (e.g., the first guest device) that is located closest to the special effect device 126 (e.g., the trapdoor). The special effect (e.g., a gust of wind) can originate from the trapdoor. Accordingly, the first guest device 34 deactivates the first indicator 94 to mimic the effect of a realistic gust of wind blowing on a torch. The first guest device 34 can then output a secondary signal 98 to the guest device 14 located closest to the first guest device 34 (eg, the second guest device 36).Each guest device 14 can be configured to receive and output a command to stop its respective indicator 42 to cause a time-delayed response to the special effect gust. The processor can be configured to delay the output 88 to other guest devices 14 to increase the length of the time-delayed response.

[0036] This technique can be used to trigger a cascading activation effect among a group of guest devices 14, where only some devices (i.e., only a subset of all guest devices 14) respond to an initial control system signal 30 sent at a first time, and this response is the activation of a particular device function in only the activated subset of devices. These activated devices 14 then send their own activation signals to different subsets of devices 14 at a later time. This cascading can continue until all devices 14 in the environment are activated. In one example, cascading activation can be used to create a wave or light cascade within the devices 14. In some embodiments, the cascade is activated automatically in the environment without user interaction with the devices 14.

[0037] The selection of the activation order for a subset of devices 14 can be based on proximity to sensors or user information associated with each individual device 14. In some embodiments, the control system 18 is configured to output the control system signal 30 to the entire environment 16, such that a first guest device 34 can receive the control system signal 30 anywhere within the environment 16. Meanwhile, in some embodiments, the control system signal 30 is configured to trigger a response in only the first guest device 34 and / or in only a subset of the guest devices 14 (e.g., selected randomly or by device type). Each guest device 14 can have an individual identity that allows the control system 18 to send the control system signal 30 to a specific guest device 14. Thus, a second guest device 36 can not respond to a control system signal output 30 intended for the first guest device 34, and therefore the second indicator 96 will not activate in response to receiving the control system signal 30. Similarly, the first guest device 34 can not respond to a control system signal 30 output for a second guest device 36, a third guest device, etc. Alternatively or additionally, the control system 18 may determine which guest devices 14 to send control system signals to based on the individual state of each guest device 14 .

[0038] In some embodiments, the first guest device 36 does not respond to the secondary signal 98 and the tertiary signal 100, and therefore the first indicator 94 does not activate in response to the secondary signal 98 or the tertiary signal 100. For example, the control system signal 30 can be configured to temporarily illuminate the first guest device 34. The first guest device 34 can then output a secondary signal 98 that temporarily illuminates the second guest device 36. The second guest device 36 can then output the tertiary signal 100. The first guest device 34 can again not illuminate in response to the tertiary signal 100, even though it can be within range of the tertiary signal 100.

[0039] Each guest device 14 can be configured to switch between multiple communication states. A guest device 14 can be configured to receive different information based on the current communication state of the guest device 14. For example, the guest device 14 can be configured to receive only certain signals in a first communication state and other signals in other communication states (e.g., a second communication state, a third communication state, etc.). Additionally, a guest device 14 can be configured to transmit different information based on the current communication state of the guest device 14. For example, a first guest device 34 can be configured to output a secondary signal 98 in the first communication state that includes instructions to a second guest device 36 to activate a second indicator 96, and to output a secondary signal 98 in the second communication state that includes instructions to a second guest device 36 to deactivate the second indicator 96. Additionally, in some embodiments, the first communication state can be configured to disable reception and / or transmission from the transmitter 56, and the second communication state can enable reception and / or transmission from the transmitter 56.

[0040] In some embodiments, the first guest device 34 can switch from a first communication state to a second communication state, or vice versa, in response to receiving the control system signal 30. Additionally, the second guest device 36 can switch from a first communication state to a second communication state, or vice versa, in response to receiving the secondary signal 98. The control system 18 can be configured to output the control system signal 30 to each guest device 14 in the environment 16 to switch / control the communication state of the respective guest device 14. The control system 18 can be configured to switch / control the communication state of each guest device 14 based on the status of the respective guest device 14. For example, the control system 18 can be configured to output the control system signal 30 to the first guest device 34 to disable transmission of the secondary signal 98 when the status signal 80 received by the control system 18 from the first guest device 34 indicates that the first guest device 34 is located within a particular area of ​​the environment 16.

[0041] 4 is a flow diagram of an embodiment of communication between guest devices 14. In the illustrated embodiment, a first guest device 34 and a second guest device 36 (e.g., wearable devices) are in communication with each other. The guest devices 14 can communicate with each other independently of communications from a control system. In some embodiments, the control system can be configured to primarily power the guest devices 14. As described above, the control system is configured to output radio waves into the environment via an emitter. Each guest device 14 (e.g., a portable device) has an energy-harvesting element configured to receive the radio waves and convert energy from the radio waves into a DC voltage to power the respective indicator 42 of the guest device 14 and other components of the guest device 14.

[0042] As described above, the guest devices 14 can be configured to interact or communicate with each other independent of communication from the control system. Communication between the guest devices 14 can be based on the respective states of the guest devices 14. As described above, a first sensor of a first guest device 34 can detect the state of the first guest device 34 (block 138) and output a status signal 80 to a first processor of the first guest device 34. The first processor can receive the status signal 80 from the first sensor (block 140). The first processor can be configured to generate a first device control signal 84 based on the state of the first guest device 34 (block 136). The first device control signal 84 can modify a first indicator 94 (block 144) (e.g., activate (block 148), deactivate (block 146), adjust an indicator setting (block 150), etc.). The first device control signal 84 may also be configured to cause the first transmitter to output (block 176) the first device signal 108. The first transmitter may be a short-range transmitter.

[0043] The second guest device 36 may be configured to receive the first device signal 108 via a second transmitter (block 178). The second transmitter may also be a short-range transmitter. A second sensor of the second guest device 36 may detect a state of the second guest device 36 (block 158) and output a second state signal 102 to the second processor 74 of the second guest device 36. The second processor may receive the second state signal 102 from the first sensor (block 160). The second processor may be configured to generate a second device control signal 86 based on both the state of the second guest device 36 and the first device signal 108 (block 156). The second device control signal 86 may modify the second indicator 96 (block 162) (e.g., activate (block 166), deactivate (block 164), adjust an indicator setting (block 168), etc.). The second device control signal 86 may also be configured to cause the second transmitter to output a second device signal 110 (block 180).

[0044] In some embodiments, the first guest device 34 is configured to receive the second device signal 110. The first processor 72 of the first guest device 34 is then configured to determine the first device control signal 84 based on both the state of the first guest device 34 and the second device signal 110. However, in other embodiments, a third guest device is configured to receive the second device signal 110.

[0045] In some embodiments, guests can initiate communication between guest devices 14. For example, a first guest 182 can move the first guest device 34 in a particular pattern. A first sensor on the first guest device 34 can detect this pattern (e.g., position over time, speed over time, etc.) and output it to the first processor via a status signal 80. The first processor is configured to recognize the pattern and cause the first guest device 34 to output a first device signal 108 based on the user-initiated first guest device 34 pattern. The first device signal 108 can be configured to illuminate a second indicator 96 on the second guest device 36. In some embodiments, the first processor is configured to recognize multiple patterns.

[0046] 5 is a perspective view of another embodiment of communication between guest devices 14. As described above, a first guest device 34 can be configured to output a first device signal 108. In the illustrated embodiment, the first device signal 108 is configured to be output to multiple guest devices 14, such that a second guest device 36, a third guest device 112, and a fourth guest device 114 are configured to receive the first device signal 108. However, each guest device 14 can respond differently to the first device signal 108. The second guest device can activate a second indicator 96 in response to the first device signal 108. The second indicator 96 can be an LED light that emits blue light 120. The third guest device 112 and the fourth guest device 114 can activate their respective indicators 116, 118 (e.g., LED lights) to emit red light 122 in response to the first device signal 108. The indicators 42 can be activated differently based on the respective device control signals. Additionally, the indicators 42 can be activated differently to provide an indication as to the status of the guest device 14. The indicators 42 can include single color light emitting diodes, multi-color light emitting diodes, audio output devices, or any combination thereof. In some embodiments, the indicators 42 include audio devices, tactile devices, or any other type of special effect. The indicators 42 can include a combination of multiple special effects.

[0047] In another embodiment, the indicator 42 is configured to activate based on the individual identification (ID) of each guest device 14. Guests may have individual IDs stored on their respective guest devices 14. In some embodiments, guests may be divided into teams based on their IDs. These IDs may cause the guest devices 14 to interact in specific ways with the control system and / or other devices 14. For example, if a first guest and a second guest are placed on a first team and a third guest and a fourth guest are placed on a second team, a first device signal 108 emitted from the first guest device 34 corresponding to the first guest may elicit a different response from the second guest device 36 than from the third guest device 112 and the fourth guest device 114. Due to the corresponding teams of guest devices 14, the second guest device 36 may emit a blue light 120 in response to the first device signal 108, and the second and third guest devices 112, 114 may emit a red light 122 in response to the first device signal 108.
