fig1 a - 1d provide an embodiment of an interactive play station ( 100 ) viewed from a variety of different directions . in these figs , the play station ( 100 ) is designed to resemble a modern shower - bath facility including a bath tub ( 101 ) and shower heads ( 103 ), but this is by no means required . the play station ( 100 ) may also include additional set dressings in the form of , for example , a shower curtain ( 105 ) and tile wall ( 107 ), so as to further resemble the standard room construction associated with modern bathing facilities . the play station ( 100 ) may include both physical mechanical objects , as described above , and other types of bathroom objects such as an air blower , but also incorporates digital interface devices . in the embodiment of fig1 a - 1d , one such device is provided which is a digital flat screen display device ( 201 ) placed in the bath tub ( 101 ) so that its surface is at a height reasonable for allowing it to show a simulation of water in the bath tub ( 101 ) by a display on its screen or other surface . the display ( 201 ) may also include any associated computer components necessary to carry out its operation as would be understood by one of ordinary skill . this includes , but is not limited to , memory components , digital processors , or more standard interfaces . in the depicted embodiment , control of the play station ( 100 ) by the child is performed by having the screen &# 39 ; s interactive touch surface ( 203 ) positioned at a position where it can effectively represent the plane of the surface of water in the bath tub ( 101 ) and having the child place and move objects on that surface . the display utilizes a read device such as , but not limited to , an interactive touch surface , a camera , a scanner ( including a 3 dimensional scanner , a 2 dimensional scanner , and an infrared emitter and scanner ), thermal sensors , sonic sensors ( microphones ) or other sensors to locate objects in proximity of the screen which are believed to be intended for interaction with the display . in this case , because they have been placed on the screen the display then presents digital material on the screen which is interactive with the position , movement , and / or orientation of the object . the play station ( 100 ) of fig1 a - 1d is generally designed to be used as part of a plush toy manufacturing environment , such as those at build - a - bear workshop ™, but this is by no means required . specifically , the play station ( 100 ) is intended to be used to “ wash ” a plush toy that a child has previously constructed ( stuffed ). as such , the play station ( 100 ) fulfills two purposes . for the child , the toy is “ cleansed ” after its assembly procedure which can help teach good hygiene procedures , bath - time routines , and other related skills . further , for the child , there is a symbolic cleansing prior to playing with the toy . from a practical point of view , the play station can actually utilize air to both fluff the toy ( improving its touch and feel ) and to remove any dust or debris that may have gotten onto the toy prior to or during its assembly . it is important to recognize that the play station ( 100 ), while emulating washing with water in the form of a standard shower or bath , does not utilize water in a preferred embodiment . this is because it is often undesirable to get a plush toy wet , particularly when the toy is likely to be carried by the child and needs to present a hygienic and inviting surface . however , the washing action does utilize the practical effect of forced air to air fluff the toy and therefore air is generally used to simulate water . fig2 - 3 and 5 - 6 provide for various screen shots which show how the digital display ( 201 ) can be used to provide for an interactive play environment . in this disclosure , the display ( 201 ) is intended to interact with two classes of physical objects . both classes are intended to be played with in conjunction with the environment . the first type of device is referred to as a “ fixed interactive device ” and the second is a “ variable interactive device .” a “ fixed interactive device ” as that term is used herein , is an object which is designed to interact with the play station ( 100 ) and is predetermined . that is , a fixed interactive device will always be the same or of a controlled arrangement . fig2 - 3 provide for various interactions with fixed interactive devices , for example , a rubber duck ( 301 ), a toy tugboat ( 303 ), and a toy bar of soap ( 305 ), although these are by no means the only interactive devices which could be provided . these devices would generally be provided as part of the play station ( 100 ) ( they are included with it ) and are of a type which would commonly be found to interact with the environment of the play station ( 100 ). as shown in these figs ., these items are all bathroom toys and representations of items that would commonly be found in a bathroom or bath . in an embodiment , the fixed interactive devices may actually be sold as self - contained toys for the child to use at home in a related environment ( e . g ., in a bath ). when a fixed interactive device is placed on the display ( 201 ), the display ( 201 ) will detect the object , identify it , and then provide a fixed play response in conjunction with it . the play response will generally be in the form of a display on the display ( 201 ) but this is by no means required and other responses may be provided in alternative embodiments . in fig2 , the rubber duck ( 301 ), when placed on the screen ( 201 ), will be provided with digital swimming feet . these will generally move with the duck ( 301 ) and will simulate the underwater appearance of a duck ( 301 ) “ swimming ” on the surface of the display ( 201 ). the display ( 201 ) or other components of the play station ( 100 ) may also provide sounds ( e . g ., such as quacking ) or may trigger other interactive components . for example , the duck ( 301 ) may be pulled by a magnet toward a certain position , chemical fog may be provided as hot water “ steam ,” or a thin water mist may be used to provide a wet sensation . the simulation of duck feet in this fig . provides that , when the child physically moves the duck ( 301 ), the duck ( 301 ) appears to swim in a manner of a real duck on water . as indicated above , it is important to note that moving the duck ( 301 ) does not make an avatar of a duck ( 301 ) move in a simulated environment ; instead the physical duck ( 301 ) is moved and the screen simply provides animated feet , something that would not generally be available to a toy duck ( 301 ). fig3 provides for two additional fixed interactive devices . in this case , the devices are a toy tugboat ( 303 ) and a toy bar of soap ( 305 ). similar to the rubber duck ( 301 ), when they are placed on the display ( 201 ), the display ( 201 ) may generate an interactive response . thus , the tugboat ( 303 ) may have a defined visible “ wake ” on the display or produce a tugboat sound and the soap ( 305 ) may result in the creation of digital bubbles , the release of a soap or bubble bath scent , and / or vibration to simulate rushing water , for example . as discussed above , it should be noted that the child &# 39 ; s interaction during play is with a physical toy ( 301 ), ( 303 ), or ( 305 ) and is not with a screen simulation of the toy . further , while the screen ( 201 ) is providing visual information to the child , the play station ( 100 ) may be providing other sensory information such as sounds ( e . g ., quaking or a tugboat horn ), smells ( e . g ., a scent of bubble bath or soap ), touch ( e . g ., vibration to simulate rushing water or blowing air ), visual ( e . g ., blue lighting to simulate rushing water ), or even tactile or taste feedback to the child . the play station ( 100 ), while being a simulated environment , is one in which multiple senses are generally engaged . a fixed interactive device ( 301 ), ( 303 ), or ( 305 ) such as those discussed above is intended for use with the play station ( 100 ) and therefore will include some form of control trigger for interacting with the display ( 201 ). while this may be a digital control chip or other digital device , in the depicted embodiment , each of the fixed devices includes machine identifiable indicia on its base . this is a simple identifier and allows for the fixed interactive devices to be readily sold for play outside of the play station ( 100 ). one embodiment of machine readable indicia is shown in fig4 where the bases for each of the fixed interactive devices include a series of three white dots ( two small and one large ) on a black background . the contrasting images can be seen by a read device connected with the display ( 201 ) so that the fixed interactive device is definitively identified as the specific device when it is placed on the display ( 201 ). in this embodiment , the read device comprises an infrared emitter and scanner located in such a manner so as to read from the surface of the display ( 201 ). in one particular embodiment , the infrared emitter and scanner can be embedded within the display ( 201 ). the infrared emitter and scanner can be comprised of infrared layers embedded with light - emitting diodes . it will be understood that any infrared emitter and / or scanner could be utilized . the dots in the base of each interactive device provides for two pieces of information . first , the play station ( 100 ) can identify what the fixed interactive device is ( e . g ., the duck ( 301 ), tugboat ( 303 ) or soap ( 305 )), and second , the display can determine the fixed interactive device &# 39 ; s orientation and movement . this allows the duck &# 39 ; s ( 301 ) feet to appear under and behind it , for instance . an obvious advantage of using a specific machine readable code is allow the play station ( 100 ) to identify the specific device . this prohibits an inaccurate response to a toy , such as , for example , putting duck feet on a bar of soap . while the inclusion of a fixed interactive device is desirable because the device will be an effective part of the play environment , it is also desirable for the play station ( 100 ) to interact with objects which are brought into the environment and which are not specifically designed to be used with it . in the depicted embodiment , these are referred to as “ variable interactive devices .” a variable interactive device is not specifically designed for use with the play station ( 100 ) and , as such , generally does not include machine readable indicia . thus , the variable interactive device has to be identified by the play station ( 100 ) in a different manner . in fig5 , the variable interactive device comprises a plush toy ( 501 ) which the user has brought with them to “ wash ” in the tub . as can be seen in fig5 , the display ( 201 ) is interacting with the plush toy . in this case , water is shown as splashing behind the toy ( 501 ). further , in conjunction with such a display the shower head ( 103 ) ( of fig2 ) may provide an air stream onto the toy ( 501 ) with an associated sound of rushing water so that the play station ( 100 ) is acting as if the plush toy ( 501 ) is under a shower of water and multiple senses ( tactile , audible , and visual ) are all engaged . thus , the plush toy ( 501 ) is able to interact with the play station ( 100 ) even though it is an object not designed for such interaction and it includes no digital components , no communication , and no machine readable indicia . the plush toy ( 501 ) will generally be one of a variety of plush toys which may be difficult to individually identify . for example , it may be difficult to determine if the toy is a bear or a dog . thus , in the embodiment of fig5 , the toy ( 501 ) is identified in a different manner than a fixed interactive device would be and the interactive components are designed to be more general . as shown in fig4 , the fixed interactive devices can be identified by the inclusion of their three relative disks . the variable device , in this embodiment , however , is identified by it having a general volume and / or shape . specifically , the variable interactive device is identified simply as being roughly ellipsoidal and within certain size parameters . this type of identification is obviously not perfect and it is possible that the play station ( 100 ) would misidentify a different device as a plush toy if it was placed on the display ( 201 ). for example , if a parent were to place his or her purse or bag on the display ( 201 ), it could be identified as a plush toy ( 501 ). however , this type of identification is generally useful for such variable interactive devices as it allows for a variety of different devices to have interaction with the play station ( 100 ) and , in this embodiment , the universe of expected outside objects being placed on the tub ( 101 ) is relatively small . that is , it is expected that an object placed on the tub ( 101 ) is a plush toy , as the tub is specifically indicated to be for washing plush toys . further , the reaction of the play environment can be more general for a variable device to allow for a more natural appearing response . as opposed to the duck ( 301 ), for example , where the display ( duck feet ) is very specific to the toy , the display of fig5 is relatively general . it is simply splashing water which would be expected from any object ( or no object ) being placed under a shower head ( 103 ). similarly , because the variable interactive device may have a variety of sizes , it is possible for the display to interact in a manner that uses the variable interactive device &# 39 ; s variable nature to its advantage . for example , the splash effect could cover an area larger than the toy ( 501 ). in this way , the effect is always visible around the toy ( 501 ) where water would be expected to cascade off into the tub ( 101 ). however , the effect under the toy is blocked by the toy itself resulting in the illusion not being spoiled . it should be recognized that fig5 and 6 provide for merely a single example of variable interactive devices which can be generally identified . other variable objects could also be identified . for example , a relatively small discrete point could be identified as a child &# 39 ; s finger which could then be used to pop bubbles or tickle the duck &# 39 ; s ( 301 ) feet . regardless of whether such point was generated by a finger , a pen , or the corner of a cellular phone , as the interaction in this case is more general ( e . g ., a popped bubble or a small ripple ), the display is appropriate for all these objects . similarly , a hand - shaped image could be identified as a hand and trigger a sound instructing one to be careful not to fall into the tub . this response can be appropriate whether the hand was the child &# 39 ; s , the parent &# 39 ; s , or the plush toy &# 39 ; s . by allowing both fixed interactive devices ( 301 ), ( 303 ), and ( 305 ) which are effectively part of the play environment of the play station ( 100 ) and variable interactive devices ( 501 ) which are usually objects from a relatively small universe of likely objects , but which are brought in externally to the play station ( 100 ), the play station ( 100 ) can provide for an immersive play environment where digital and mechanical operations work together to provide a particular play activity having a fun , hands - on component . in effect , the play station ( 100 ) utilizes a digital simulation to provide visual play , while interacting with physical objects that may or may not be designed to interact with it . the play station ( 100 ) can do so in a manner that engages the user &# 39 ; s senses in a much more direct environment than a pure screen simulation . while in some embodiments it would be desirable for the play station ( 100 ) to be played with for an indeterminate length of time , in a situation , such as but not limited to as part of a retail toy manufacturing experience , it may be desirable to have play terminate after certain conditions occur or after a specified time period has elapsed . in this regard , the display ( 201 ) may show a representation of a plug being pulled in the tub ( 101 ) and that the “ water ” is draining . this representation on the display ( 201 ) would be designed to terminate the play experience and end the session . specifically , the play is terminated because the tub ( 101 ) no longer has water and , thus , it would not be expected to be interactive with the user . a tub ( 101 ) without water would presumably have no expected interaction as there is no water to interact with . termination of the visual display ( and any other associated sensory displays ), thus , provides a cue that play at the play station ( 100 ) is over and the child should go do something else . after a period of time has elapsed , the play station ( 100 ) can reset ( either in a simulation of filling the tub ( 101 ), or simply a reset sequence where the tub ( 101 ) simply goes from empty to full ) to await the next user . alternatively , it may be desirable to have the play terminate after a specified time period has elapsed or when all tasks have been completed , for example , when the play station ( 100 ) comprises a task - based “ game .” in such a situation , the user may have a specified period of time to complete a variety of tasks before the time has elapsed . for example , after the time period begins , the user may have a list of designated tasks and the play station ( 100 ) may instruct the user to complete the same . such tasks could include , for example , “ use the soap ,” “ wash behind the ears ,” “ dry off ,” and the like . the play would be completed either when time has elapsed or when the user has completed all the tasks . it should be recognized that , while the disclosure above is focused on the play station ( 100 ) interacting with non - digital devices in the form of fixed interactive devices ( 301 ), ( 303 ), or ( 305 ) and variable interactive device ( 501 ), the play station ( 100 ) can , in an embodiment , also interact with other digital devices which are capable of more advanced communication . for example , the play station ( 100 ) may be able to retrieve information from other networked or otherwise paired devices to provide for sharing of information from the play station ( 100 ) to other stations in an interactive play environment , or may be able to receive information from a user device , such as , but not limited to , a smartphone ( e . g ., via a bluetooth or cellular connection ), a tablet computer ( e . g ., connecting to the tub via the internet ), or a digital component in the toy itself . for example , if the toy has a name which has been entered into a networked digital device , the play station ( 100 ) may refer to the toy by name . this provides a further level of interactivity if the toys brought to the tub are capable of such enhanced interaction . while the invention has been disclosed in conjunction with a description of certain embodiments , including those that are currently believed to be the preferred embodiments , the detailed description is intended to be illustrative and should not be understood to limit the scope of the present disclosure . as would be understood by one of ordinary skill in the art , embodiments other than those described in detail herein are encompassed by the present invention . modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention .
an interactive play station designed to provide for play which utilizes digitally generated content , mechanical or other physical objects , and digital control to simulate a physical environment which physical objects can appear to interact with . in this regard , the play station is a mixed reality or augmented environment that comprises both real and virtual elements .
