Abstract:
Various embodiments associated with a commencement sound and a conclusion sound are described. The commencement sound can be a firing sound, such as a sound of a bullet exiting a rifle. The conclusion sound can be an impact sound, such as a sound of the bullet impacting a concrete wall. These sounds can replicate what it sounds like to have an experience around someone without actually subjecting that person to the experience.

     BACKGROUND 
       [0002]    During basic and advanced training, soldiers can be taught soldiering skills to make them more efficient and productive members of a military force. In one example, a soldier can be trained how to effectively drive a sports utility vehicle over rough terrain. However, this training can be limited if it does not properly simulate a real world situation for the soldier. Therefore, training can be tailored to vividly resemble a potential real world situation.

     DETAILED DESCRIPTION 
       [0020]    Various sounds can be used to recreate a real-world experience, such as a commencement sound (e.g., firing sound), a conclusion sound (e.g., impact sound), and a reverberation sound. These sounds can be realistic, high fidelity sounds used in a realistic location for training purposes, therapy purposes, entertainment purposes, etc. For example, using gunfight sounds in soldier or police training can make the training more vivid and authentic, can better prepare soldiers and police for stressful environments they may encounter, etc. However, practicing these aspects can have the benefit of not actually placing the soldiers and police in danger and not using actual weapons that can be costly. 
         [0021]    The following includes definitions of selected terms employed herein. The definitions include various examples. The examples are not intended to be limiting. 
         [0022]    “One embodiment”, “an embodiment”, “one example”, “an example”, and so on, indicate that the embodiment(s) or example(s) can include a particular feature, structure, characteristic, property, or element, but that not every embodiment or example necessarily includes that particular feature, structure, characteristic, property or element. Furthermore, repeated use of the phrase “in one embodiment” may or may not refer to the same embodiment. 
         [0023]    “Computer-readable medium”, as used herein, refers to a medium that stores signals, instructions and/or data. Examples of a computer-readable medium include, but are not limited to, non-volatile media and volatile media. Non-volatile media may include, for example, optical disks, magnetic disks, and so on. Volatile media may include, for example, semiconductor memories, dynamic memory, and so on. Common forms of a computer-readable medium may include, but are not limited to, a floppy disk, a flexible disk, a hard disk, a magnetic tape, other magnetic medium, other optical medium, a Random Access Memory (RAM), a Read-Only Memory (ROM), a memory chip or card, a memory stick, and other media from which a computer, a processor or other electronic device can read. In one embodiment, the computer-readable medium is a non-transitory computer-readable medium. 
         [0024]    “Component”, as used herein, includes but is not limited to hardware, firmware, software stored on a computer-readable medium or in execution on a machine, and/or combinations of each to perform a function(s) or an action(s), and/or to cause a function or action from another component, method, and/or system. Component may include a software controlled microprocessor, a discrete component, an analog circuit, a digital circuit, a programmed logic device, a memory device containing instructions, and so on. Where multiple components are described, it may be possible to incorporate the multiple components into one physical component or conversely, where a single component is described, it may be possible to distribute that single component between multiple components. 
         [0025]    “Software”, as used herein, includes but is not limited to, one or more executable instructions stored on a computer-readable medium that cause a computer, processor, or other electronic device to perform functions, actions and/or behave in a desired manner. The instructions may be embodied in various forms including routines, algorithms, modules, methods, threads, and/or programs including separate applications or code from dynamically linked libraries. 
         [0026]      FIG. 1  illustrates one embodiment of a system  100  comprising a firing emitter  110 , an impact emitter  120 , and two echo emitters  130  and  140 . While two echo emitters  130  and  140  are shown more or less echo emitters can be used. The emitters  110 - 140  can work together to provide a sound experience that is realistic for a user  150 . In one example, the sound experience can be of a bullet being fired in the general vicinity of the user. The firing emitter  110  can emit a fire sound  160  that replicates a sound of the bullet leaving a rifle. The impact emitter  120  can emit an impact sound  170  that replicates a sound of the bullet impacting a target such as a hillside. The echo emitters  130  and  140  can produce echo sounds  180  and  190  respectively. Example echo sounds  180  and/or  190  can include a sound of a bullet passing by the head of the user  150 , reverberations from the rifle, and/or resonance from the bullet impacting the target. Thus, various parts of a sound experience can be produced by the system  100 . 
         [0027]      FIG. 2  illustrates one embodiment of a system  200  comprising a source speaker component  210  and a destination speaker component  220 . The source speaker component  210  (e.g., firing emitter  110  of  FIG. 1 ) can be configured to emit a commencement sound (e.g., fire sound  160  of  FIG. 1 ) that communicates an initiation of an object in travel. The destination speaker component  220  (e.g., the impact emitter  120  of  FIG. 1 ) can be configured to emit a conclusion sound (e.g., impact sound  170  of  FIG. 1 ) that communicates a result of the object in travel (e.g., the object in travel has an initiation of a single fire, but a result of multiple fragments impacting a target at different times). Thus the system  200  can create a sound experience. 
         [0028]    This sound experience can be used in various applications. In one example, the system  200  can create a sound experience for soldiers in training. While the soldiers are training they can hear sounds similar to that of combat which can make them more prepared to perform while under the stresses of combat. Similarly, in actual combat operations the sound experience can be used to confuse an enemy force or in a law enforcement operation to confuse captors in a hostage situation. Additionally, the system  200  can be used in a therapeutic environment for soldiers, such as to aid in treatment of Post Traumatic Stress Disorder (PTSD) (e.g., use sounds to help patients disassociate sounds with trauma and to gradually desensitize patients from those sounds). In addition to military applications, aspects disclosed herein can be used in non-military applications. In one example, the system  200  can be used in an amusement park to make a ride seem more realistic. In this example, the source speaker component  210  can emit a sound of a lightning bolt coming from the sky and the destination speaker component  220  can emit a sound of the lightning bolt impacting a tree on the ground. 
         [0029]    The source speaker component  210  can be retained by a first housing while the destination speaker component  220  can be retained by a second housing that is physically separate from the first housing. Therefore, the source speaker component  210  can be physically separate from the destination speaker component  220 , such as being on different sides of a listener. The destination speaker component  220  can emit the conclusion sound after a start of emission of the commencement sound as well as after the end of emission of the commencement sound. Therefore, the source speaker component  210  from the first housing can emit a sound of a weapon such as an artillery cannon firing a shell (e.g., from a speaker), and after a period of time the destination speaker component  220  from the second housing can emit a sound of the shell impacting a target such as an abandoned building. 
         [0030]    In one embodiment, the first housing retains a transmitter (e.g., part of the source speaker component  210 ) while the second housing retains a receiver (e.g., part of the destination speaker component  220 ). The housings can each retain a transmitter and receiver. The transmitter can be configured to transmit to the receiver a message that provides information with regard to when in time the destination speaker component  220  should emit the conclusion sound (e.g., a set time, that the conclusion sound should be emitted after a set time, that no conclusion sound should be emitted, etc.). Therefore, the first housing and second housing can be in communication with one another. This communication can be used to coordinate time emission of the commencement sound and conclusion sound. In one example, the first housing can emit the commencement sound and send a message to the second housing that the commencement sound is emitted. The second housing can then emit the conclusion sound and send a message back to the first housing that the conclusion sound has been emitted. In response to receiving the message from the second housing the first housing can emit another commencement sound (e.g., the same commencement sound, a different commencement sound, etc.). 
         [0031]    In one embodiment, the destination speaker component is configured to monitor emission of the commencement sound to produce a monitor result. The destination speaker component  220  can be configured to decide a time to emit the conclusion sound based, at least in part, on the monitor result. The destination speaker component  220  can be configured to emit the conclusion sound at the time. Therefore, as opposed to directly communicating with one another, the destination speaker component  220  can determine on its own when to emit the conclusion sound based on when the commencement sound is emitted. 
         [0032]    The source speaker component  210  and the destination speaker component  220  can share speaker hardware or be hardware independent of one another. In one example, the source speaker component  210  and the destination speaker component  220  have their own individual speakers and share a speaker (e.g., each component has their own speaker and then share a speaker, thus each component can function with two physical speakers). In another example, a single speaker can be employed by both the source speaker component  210  and the destination speaker component  220 . 
         [0033]      FIG. 3  illustrates one embodiment of a system  300  comprising the source speaker component  210 , the destination speaker component  220 , and an echo speaker component  310 . The echo speaker component  310  (e.g., the echo emitters  130  and  140  of  FIG. 1 ) can be configured to emit a reverberation sound (e.g., echo sounds  180  and  190  of  FIG. 1 ) that communicates the echo sound of the object in travel (e.g., echo that would result from the impact of the object on a target after travel completion). 
         [0034]    In one embodiment, the reverberation sound is emitted later in time from the conclusion sound. In one example, the reverberation sound is the reverberation from the initiation of the object in travel (e.g., sound of artillery cannon vibration), from the result of the object in travel (e.g., dirt hitting the ground dislodged from cannon shell hitting a hillside), or from a collateral action (e.g., sound of bodies leaping to the ground to take cover). Therefore, the reverberation sound can be emitted later in time from the commencement sound and/or the conclusion sound. 
         [0035]      FIG. 4  illustrates one embodiment of a system  400  comprising the source speaker component  210 , the destination speaker component  220 , a destination sensory component  410 , and a source sensory component  420 . The destination sensory component  410  can be configured to emit a conclusion non-sound sensory emission that communicates the result of the object in travel. The source sensory component  410  can be configured to emit a commencement non-sound sensory emission that communicates the initiation of the object in travel. Non-sound sensory emission can include visual emission (e.g., light flashes), touch emissions (e.g., dirt flying into the air that contacts the user  150  of  FIG. 1 ), smell emissions (e.g., odor of gunpowder), and/or taste emissions (e.g., smoke released with a particular flavor). These non-sound sensory emissions can be used to make the sound experience more realistic. 
         [0036]      FIG. 5  illustrates one embodiment of a system  500  comprising the source speaker component  210 , the destination speaker component  220 , a reception component  510 , and a propulsion component  520 . The reception component  510  can be configured to receive a sound instruction  530 , where the source speaker component  210 , the destination speaker component  220 , or a combination thereof emit their respective sound in accordance with the sound instruction  530 . The sound instruction  530  can include a sound file for use and/or be an instruction to use a sound file (e.g., a sound file retained locally, a sound file that should be downloaded, etc.). 
         [0037]    The propulsion component  520  can be configured to cause movement of a housing that retains at least part of the system  500  to a location that is based, at least in part, on the sound instruction  530 . This movement of the system can be tele-operation (e.g., by way of an interface) or proactive (e.g., automatic). Thus, the system  500  can be mobile (e.g., employ wheels to drive, employ rotors to fly, employ a boat engine to travel by water, etc.). The sound instruction  530  can, for example, state that the sound should emit x feet from a right side of the user  150  of  FIG. 1 , where x is a real number. The propulsion component  520  can cause movement of the housing such that a speaker of the source speaker component  210  and/or destination speaker component  220  is positions x feet away from the right side of the user  150  of  FIG. 1 . As the user  150  of  FIG. 1  moves, the housing can move along with her by way of the propulsion component. The housing can also be moved from a first location to a second location by the propulsion component  520  and remain in the second location for a set period of time. 
         [0038]      FIG. 6  illustrates one embodiment of a system  600  comprising the source speaker component  210 , the destination speaker component  220 , the reception component  510 , the propulsion component  520 , an analysis component  610 , an identification component  620 , a recognition component  630 , and an implementation component  640 . The analysis component  610  can be configured to analyze the sound instruction  530  of  FIG. 5  to produce an analysis result (e.g., analysis of the sound instruction  530  of  FIG. 5  occurs after reception by the reception component  510 ). The identification component  620  can be configured to identify a sound file to use from a sound file set of two or more sound files based on the analysis result (e.g., the analysis component  610  and the identification component  620  work together to determine which sound file the instruction is telling the system  600  to use for emission). The recognition component  510  can be configured to read the sound file from a non-transitory computer-readable medium (e.g., the computer-readable medium  920  discussed below) to produce a sound file result. The implementation component  640  can be configured to cause emission of the commencement sound, the conclusion sound, or a combination thereof in accordance with the sound file result. 
         [0039]    In one example, the system  600  can retain a memory chip that retains a set of sound files as well as an internal clock. The sound instruction  530  of  FIG. 5  can designate which sound file to play at a certain time and this can be recognized by the analysis component  610 . In this example, the sound instruction  530  of  FIG. 5  can be an instruction to play a commencement sound of an AK-47 firing. The identification component  620  can find an AK-47 sound file in the memory chip. More than one AK-47 sound file can exist and if the instruction does not specify then the system  600  can use internal logic to select a sound file to use. Alternatively, if no AK-47 sound file exists on the memory chip, the system  600  can improvise (e.g., identify a similar sounding sound file) or send an error message. The AK-47 sound file can include commencement, conclusion, and/or reverberation sound information (e.g., as one file, as three separate files, etc.). Once identified, the recognition component  630  can find the AK-47 sound file and thus give the system  600  access to the AK-47 sound file. The implementation component  640  can cause emission of the appropriate sound (e.g., send an instruction to the source speaker component  210  to play an AK-47 commencement sound from the sound file). 
         [0040]      FIG. 7  illustrates one embodiment of a system  700  comprising the source speaker component  210 , the destination speaker component  220 , and a housing  710 . The housing  710  can function as the housing discussed above with regard to  FIG. 5 . The housing  710  can retain components disclosed herein, such as the source speaker component  210  and/or the destination speaker component  220 . Other example components that the housing  710  can retain, such as along with the source speaker component and the a destination speaker component, can be the analysis component  610  of  FIG. 6 , the identification component  620  of  FIG. 6 , the recognition component  630  of  FIG. 6 , and the implementation component  640  of  FIG. 6 . 
         [0041]    The source speaker component  210  can be configured to emit a commencement sound that communicates an initiation of a first object in travel. The destination speaker component  220  can be configured to emit a conclusion sound that communicates a result of a second object in travel. Thus, a single system (e.g., the system  700 ) can retain the capability of functioning as a source and destination for sound. 
         [0042]    In addition to the source speaker component  210  and the destination speaker component  220 , the system  700  can comprise the echo speaker component  310  of  FIG. 3 . The echo speaker component  310  of  FIG. 3  can be configured to emit a reverberation sound that communicates an echo of a third object in travel (e.g., the first object in travel, the second object in travel, and the third object in travel are all different objects). The housing  710  can retain the echo speaker component. Thus, a single system (e.g., the system  700 ) can retain the capability of functioning as a source and destination for sound as well as supply reverberation sound. 
         [0043]    In one example, the system  700  can comprise a single speaker along with a hardware and software combination (e.g., the system  800  discussed below can retain software). Depending on the instruction provided, the system  700  can emit the commencement sound, the conclusion sound, or the reverberation sound (e.g., of different objects or of the same object). Thus one system can function in different roles. Further, the source speaker component  210  and the destination speaker component  220  (e.g., along with the echo speaker component  310  of  FIG. 3 ) can be one physical items that functions in different roles. 
         [0044]    The first object in travel and the second object in travel are not the same object in travel (e.g., not the identically same object travelling at the same time) and the same can be said for the third object in travel. In one embodiment, the first object in travel and the second object in travel can be different object types (e.g., the first object is a bullet and the second object is an artillery shell). In one embodiment, the first object in travel and the second object in travel are different iterations of the same object type (e.g., the first object and second objects are both water crashing as a wave—one earlier in time and one later in time). 
         [0045]      FIG. 8  illustrates one embodiment of a system  800  comprising a processor  810  and a computer-readable medium  820  (e.g., non-transitory computer-readable medium). The computer-readable medium  820  can be retained by the housing  710  of  FIG. 7 . In one embodiment the non-transitory computer-readable medium  820  is communicatively coupled to the processor  810  and stores a command set executable by the processor  810  to facilitate operation of at least one component disclosed herein (e.g., the source speaker component  210  of  FIG. 2  and/or the destination speaker component  220  of  FIG. 2 ). In one embodiment, components disclosed herein (e.g., the source speaker component  210  of  FIG. 2  and/or the destination speaker component  220  of  FIG. 2 ) can be implemented, at least in part, by way of non-software, such as implemented as hardware (e.g., implemented by way of the processor  810  and/or computer-readable medium  820 ). In one embodiment the non-transitory computer-readable medium  820  is configured to store processor-executable instructions that when executed by the processor  810  cause the processor  810  to perform a method disclosed herein (e.g., the methods  1200  and  1300  discussed below). 
         [0046]      FIG. 9  illustrates one embodiment of a speaker component  900  comprising an antenna  910 , a speaker  920 , the processor  810 , and the computer-readable medium  820 . The speaker component  900  can comprise mechanical hardware to facilitate movement. The speaker component  920  can function as the source speaker component  210  of  FIG. 2 , the destination speaker component  220  of  FIG. 2 , and/or the echo speaker component  310  of  FIG. 3  depending on circumstances. The antenna  910  of the speaker component  900  can wirelessly communicate with a system (e.g., a central processing system, another speaker component, etc.) and receive am instruction for a sound to be broadcast. The speaker  920  of the speaker component can be used to broadcast the sound. 
         [0047]    In one example, the antenna  910  can be in communication with a computer system that send an instruction to play ‘file A’ that is retained in the computer-readable medium  820 . The processor  810  can follow the instruction, access ‘file A’, and cause the speaker to play the sound associated with ‘file A.’ The speaker component  900  might not be informed if it is functioning as the source speaker component  210  of  FIG. 2 , the destination speaker component  220  of  FIG. 2 , or the echo speaker component  310  of  FIG. 3 . To put another way, the speaker component  900  can function without knowledge of its own role. However, ‘file A’ may be designated as a conclusion sound and therefore the speaker component  900  may recognize that it is functioning as the destination speaker component  220  of  FIG. 2 . In one embodiment, the computer-readable medium  820  can retain a sound file set for various situations, such as ‘file A.’ In addition, the computer-readable medium  820  can retain protocol for component operations, positional calculations, software for implementations of the graphical user interface, software for communicating with other entities (e.g., the central processing system). 
         [0048]    In one example, the antenna  910  can receive the instruction from the computer as well as ‘file A’ from the computer. Therefore, as opposed to accessing a file retained in the computer-readable medium  820  the file can be received concurrent with the instruction. ‘File A’ can be retained in the computer-readable medium  820  for future use such that ‘file A’ is not required to be sent for every use of ‘file A’ by the speaker component  900 . 
         [0049]      FIG. 10  illustrates one embodiment of an interface  1000  comprising a sound selection portion  1010 , a source selection portion  1020 , a destination selection portion  1030 , an echo selection portion  1040 , and a timing selection portion  1050 . The interface  1000  can be a graphical user interface that is displayed on a touch screen associated with the system  800  of  FIG. 8 . The interface  1000  can be used by a person (e.g., an instructor) to direct the sound experience. This direction can be real-time or pre-loaded. For a pre-loaded example, a programmer can use the interface  1000  to set up a sound experience loop, such as a sound experience that is repeated for an amusement ride. For a real-time example, soldiers can be training in a complex tactical environment. This environment can have a variety of places where the soldiers can take cover. To simulate a real-world experience, enemy combatants may attempt to shoot in a direction where the soldiers are taking cover. Depending on where the soldiers take cover sounds can be selected by a training coordinator by way of the interface  1000 . 
         [0050]    The sound selection portion  1010  can be used to select a sound to be emitted (e.g., single sound such as a single conclusion sound, sound set that comprises the commencement sound and conclusion sound, etc.). The source selection portion  1020 , the destination selection portion  1030 , and the echo selection portion  1040  can be used to select where the sound is to be emitted. This selection can be for a specific speaker or for an area to emit the sound (e.g., a component selects a best speaker in the area for use, or if no speaker is in the area then the component selects a speaker to move to that area via the propulsion component  520  of  FIG. 5 ). The timing selection portion  1050  can be used to select when the sound is to be emitted. Portions of the interface  1000  can be multi-layered, such as the sound selection portion  1010  first asking whether a gun or cannon sound is to be used and if gun is selected then a second question can be which type of gun. 
         [0051]    While the interface  1000  is shown, it is to be appreciated by one of ordinary skill in the art that the sound experience can be proactively created. In one example, the system  800  of  FIG. 8  can retain an artificial intelligence component that can make inferences and decisions. Information can be gathered (e.g., soldier movement) and based on this information the artificial intelligence component can determine what sounds to emit, where to emit those sounds, when to emit those sounds, which speaker(s) to use, where to move at least one speaker, etc. The artificial intelligence component can be self-learning, such that can update logic base on effectiveness of a sound experience. 
         [0052]    Furthermore, the interface  1000  can be implemented with fewer than the portions shown and/or be used with some portions being ignored. In one example, a person can select the sound and source by way of portions  1010  and  1020  and a component can selection the destination based on various factors (e.g., simulated wind speed, simulated rain, etc.). Once the interface  1000  gathers appropriate information and/or the component makes the appropriate selection(s) data the proper destinations can be identified and information can be sent (e.g., wirelessly). Example information are sound files themselves, instructions on what sound files to use, attenuation factors, time information, etc. In addition, different information can be sent to different components (e.g., a firing sound file sent to the source speaker component  210  and an impact sound file sent to the destinations speaker component  220 ). 
         [0053]    As an example sequence, a person can enter data by way of the portions  1010 - 1050 . A component can calculate a plan for various components (e.g., components  210  and  220  of  FIG. 2 ) and send to each component in use data such that the plan can be properly implemented. The components can then use this data to implement the plan. 
         [0054]      FIG. 11  illustrates one embodiment of an interface  1100  comprising an item selection portion  1110  and an impact selection portion  1120 . As opposed to the detailed interface  1000  of  FIG. 10 , the interface  1100  can be simpler with the two portions  1110  and  1120 . The item selection portion  1110  can be used to select an item (e.g., bullet, rifle, small arms, grenade, mortar, artillery, rocket, etc.) and the impact point selection portion  1120  can be used to select where the item would theoretically impact and thus indirectly select where sound is emitted, when sound is emitted, etc. In one example, the impact selection portion is a map where an administrator decides where impact should occur (e.g., anywhere on the map, select areas where a fixed speaker is located, etc.). A component can perform remaining tasks, such as deciding what physical speakers should be used to emit sound (e.g., which components to use), a timing pattern for sound emission, determining which sound file to use (e.g., three sound files that are selected—one for firing, one for impact, and one for echo), performing calculations based on administrator designations, initiate sound emission, etc. In one example, the administrator can select the item by way of portion  1110 , but portion  1120  can be used to request random impact. 
         [0055]      FIG. 12  illustrates one embodiment of a method  1200  comprising two actions  1210  and  1220 . At  1210  there is identifying an initiation command entered upon a graphical user interface (e.g., the interface  1000  of  FIG. 10  or the interface  1100  of  FIG. 11 ) for an audible sequence (e.g., one or more sounds (e.g., command sound and commencement sound), multiple sounds and lights, etc.). At  1220  causing implementation of the audible sequence in response to identifying the initiation command can occur. In one embodiment, this identification can occur at a terminal that displays the graphical user interface and the causing is sending a command. In one embodiment, this identification can occur at a speaker component remote from the terminal and causing is performing the emission of the audible sequence local to the speaker component. 
         [0056]    In one embodiment, the initiation command comprises a location command that identifies a location from which at least part of the audible sequence is emitted. Action  1220  can include causing at least part of the audible sequence to be outputted from the location. Also, action  1220  can include causing a hardware element to move to the location and causing the audible sequence to, at least in part, be outputted after the hardware is moved to the location. 
         [0057]    The audible sequence can comprise a firing audible portion and an impact audible portion. The firing audible portion can is implemented at a first location while the impact audible portion is implemented at a second location. The second location is distinct from the first location (e.g., they are physically separate, they are remote from one another, etc.) and the firing audible portion can be implemented earlier in time than the impact audible portion. In addition to the firing audible portion and the impact audible portion, the audible sequence can comprise an echo audible portion. The echo audible portion can be implemented at a third location that is distinct from the first location and from the second location. The echo audible portion can be implemented later in time than the impact audible portion. 
         [0058]      FIG. 13  illustrates one embodiment of a method  1300  comprising five actions  1310 - 1350 . By way of an interface, such as the interface  1000  of  FIG. 10 , a user can enter location information for one or more source speaker component  210  of  FIG. 2 , one or more destinations speaker component  220  of  FIG. 2 , and/or one or more echo speaker component  310  of  FIG. 3  and at  1310  this information can be recognized and sent (e.g., firing location information to the source speaker component  210  of  FIG. 2 ). Robots that operate as these components can move to the indicated location and return a confirmation at  1320 . Once appropriate confirmations are received the interface  1000  of  FIG. 10  can have an execute command portion become available, a user can press the portion, and in response to this pressing at  1330  the execute command can be selected, at  1340  an instruction to emit is transferred (e.g., with appropriate sound file information), and at  1350  emission can occur. If appropriate confirmations are not received, a component can perform corrective action (e.g., instruct another component to move, re-send the information, etc.).
