     DESCRIPTION OF EMBODIMENTS OF THE INVENTION 
     The disclosure relates to household appliances having a transparent, touch screen user interface overlaying a window of the appliance. The window, while illustrated on a door, can be located on other areas of the appliance. While the disclosure is written in the context of an oven with a door having a window and the transparent, touch screen user interface on the window, the disclosure is applicable to any type of appliance with a window, including, without limitation, a refrigerator, microwave, toaster oven, dishwasher, clothes washer, and dryer. 
     Referring to  FIG. 1 , a household cooking appliance is shown in the form of an oven  10  and can be used for cooking one or more food items. The oven  10  can include an outer chassis  12  including a top wall  14 , a bottom wall  16 , opposing sidewalls  18 , and a rear wall  20  to define an interior  22  forming a cooking chamber for the oven  10 . An access opening  24  is provided opposite the rear wall  20  for accessing the interior  22 . A door  30  can be pivotably mounted to the chassis  12  at the bottom wall  16 , pivotable between an open position ( FIG. 1 ) providing access to the interior  22  at the access opening  24  and a closed position ( FIG. 2 ), closing the interior  22  at the access opening  24 . A gasket  28  can be provided on the edges of the top wall  14 , the bottom wall  16 , and the sidewalls  18  for sealing the interior  22  at the door  30  when the door  30  is in the closed position. A handle  26  can be provided on the door  30  for selectively moving the door  30  between the opened position and the closed position. A front panel  29  is provided on the chassis  12  above the access opening  24 . Additionally, a mask  31  is at least partially provided on the front panel  29 , while the mask  31  extends onto the front of the door  30  (best seen in  FIG. 2 ). The mask  31  can be opaque, preventing a user viewing portions of the oven  10  through the mask  31 . 
     A first camera  32 , schematically illustrated in broken line and shown in two alternative positions, can be provided on the top wall  14  for viewing the interior  22  of the oven  10 , while any position for the camera to view the interior  22  is contemplated. The first position for the first camera  32  is in the center of the top wall  14 . While the camera  32  is shown as centrally provided on the top wall  14 , it is contemplated that the camera  32  can be provided at any position suitable for viewing the interior of the oven  10 . In the second alternate position, the camera  32  is provided at the front-right portion of the oven, when viewed from the front. It should be appreciated that multiple different positions for the interior camera  32  are contemplated, and that the two positions are shown to illustrate the variability of positioning the first camera  32 . Additionally, multiple interior cameras  32  are contemplated to record and generate a three-dimensional image of a food item within the oven based upon the different recorded angles from the multiple cameras. 
     The camera  32  can provide for imaging and recognizing a food item that is provided within the oven  10 , or generating an image of a food item contained within the interior  22 . More specifically, the camera  32  can generate a signal representing an image or video, which can be provided to a controller for interpreting the signal. In one example, the oven  10  can automatically cook the food item based upon recognition of the food item and monitoring throughout the cooking process. Alternatively, the camera  32  can be used to image the food item for monitoring by the user via a display, without requiring the user to open the oven  10  to inspect the food item as it cooks. Further still, the camera  32  can include a zoom feature, as well as digital zoom or panning within range of the camera  32 , to permit closer inspection of different portions of the food item. In one example, the camera  32  can record images at a quality suitable for high definition reproduction at a 1920×1080 screen resolution, while other resolutions or qualities are contemplated. While described as a camera, any suitable sensor for imaging or recording the interior  22  or portions in front of the oven  10  is contemplated, such as a thermo-imaging sensor, for example. 
     Additionally, a second camera  38  can be provided on the front panel  29  for viewing the area in front of the oven  10 , such as a user using the oven  10 . The second camera  38  can be programmed to identify a user, such as facial recognition, or to focus on the eyes of a user or a position thereof to track where the user is looking at the oven  10 . More specifically, the camera  32  can generate a signal representing an image or video, which can be provided to a controller for interpreting the signal. Such a signal can be interpreted to determine a user&#39;s face, such as by using facial recognition software or eye identification software. Additionally, one or more users can be stored in a controller, such that the oven  10  can recognize a particular user based upon the facial or eye recognition. Furthermore, the second camera  38  can utilizing image analysis to determine height, sideways position of the user, as well as depth from the oven  10 , such that the camera  38  can be used to detect at least two or up to three axes to accurately determine a user&#39;s position or movement. For example, the second camera  38  can be used to determine a lateral or side-to-die movement of the user. Additionally, the second camera  38  can be used to determine a distance of the user from the oven  10 . 
     A set of rails  34  are provided on the sidewalls  18  for mounting one or more racks ( FIG. 4 ) in the interior  22 . While only one set of rails  34  are shown, it should be understood that a complementary set of rails are provided on the other sidewall  18 , obscured by the perspective view of  FIG. 1 . Furthermore, while only two rails  34  are shown, any number of rails is contemplated. 
     An optional set of vents  36  can be provided on the rear wall  20  facing the interior  22  for passing a volume of air into or out of the interior  22 , such as for circulating a flow of heated air to provide for a convection cycle for the oven  10 . The vents  36  can include one or more openings into the interior  22 , while the particular louvers or covers can be formed in a way to hide the openings from view from the front. More specifically, the openings of the vents  36  can face the bottom wall  16 , for example. Alternatively, the rear wall  20  can have no visible structure, and can include a flat back panel. 
     Furthermore, additional elements or components can be provided in the interior of the oven  10 , such as a sensor  58 , a heating element  54 , and a fan  56 . The sensor  58  need not be a single sensor  58 , but can be multiple different sensors for making measurements of the interior of the oven  10 . Exemplary sensors can include but are not limited to a temperature sensor, an infrared sensor, a food temperature probe, or a rack sensor. The heating element  54  can be a gas heater or an electric heater, for example. 
     Lights  40  are provided on the top wall  14  for illuminating the interior  22  of the oven  10 . While shown as positioned in the top wall  14  near the front of the oven  10 , the lights can be positioned anywhere to suitably illuminate the interior  22  of the oven as well as the door  30  when in the closed position. The lights  40  can also be used to illuminate the door  30  and a display  48  on the door  30 . In one example, the lights  40  can be used to passively light the door  30  and display  48 , effectively lighting the display  48  via ambient light reflected about the interior  22  of the oven. In another example, the lights  40  can actively light the door  30  and the display  48 , with the lights  40  being dedicated to lighting the display  48  and directing light toward the display  48 . Furthermore, the lights  40  can be tailored to either the door  30  or the camera  38 , or both. More specifically, the lights  40  can be tailored to illuminate the door  30  or the display thereon, including a transparent, touchscreen display, discussed in detail herein. Additionally, the lights  40  can be tailored to the camera  38 , such as being an ultraviolet light when the camera  38  is an ultraviolet imaging camera. 
     A display  48  including a user interface  50  is provided on the door  30 . The display  48  can be a transparent, touchscreen display, permitting a user to selectively view the interior of the oven  10  based upon the imaging provided on the current user interface  50 . In one example, the display can be a liquid crystal display (LCD), and can be self-lit or backlit. Alternatively, the display can be a light emitting diode (LED) display that can be self-lit, such as using organic LEDs or active matrix, organic LEDs, for example. Additionally, the user interface  50  can provide for control and operation of the oven  10 , as well as facilitating use of the appliance through user interaction with the user interface  50 . More specifically, the user interface can include an interactive interface, such as a software program shown on the display  48 . The user can interact with the user interface  50  by touching or otherwise manipulating the user interface  50 . Such interaction with the user interface  50  can be used by the user to control operation of the oven  10 , as well as facilitate use of the oven  10 . For example, the user interface can provide information to the user related to operation of the oven  10 , or other relevant information such as recipe information or other cooking-related information. 
     Referring to  FIG. 2 , the door  30  is shown in the closed position, sealing the interior  22  of the oven  10 , with a system provided on the user interface  50  permitting a user to interact with the oven  10 . The user interface  50  and system thereon as shown is exemplary, and should not be limiting of the oven  10 . 
     A controller  52  can be provided within the oven  10  for controlling operation of the oven  10 , as well as sending and receiving information to the user interface  50  for interaction with the user. The additional front, external camera  38  can be provided on the oven  10  for viewing a user interacting with the oven  10 , and can be in communication with the controller  52 . 
     When the door  30  is in the closed position, the user interface  50  can be operational and illuminated, permitting interaction by the user. Alternatively, the user interface  50  can be operated by a timer when the oven is not in use, but the door is in the closed position, turning off the display  48  when not in use. Furthermore, when the door  30  is in the opened position, the display  48  can be turned off, as the user will not be able to view the display  48  with the door opened. The user interface  50  can further display an image of a food item contained within the interior  22 . The image can be an augmented image, for example, or can be generated as a three-dimensional image of the food item. 
     While the interior  22  is currently visible through a transparent portion of the user interface  50 , it is further contemplated that the portion of the user interface  50 , as shown, can include an augmented reality image of a food item being cooked or to be cooked. In one example, a user can select a desired food item to be cooked, and the user interface  50  can provide a virtual or augmented three-dimensional image of the final result, or preview the final cooking result along the cooking process. 
       FIG. 3  is a schematic view of the controller  52  coupled to the various components of the oven  10 . The controller  52  can be operably and communicably coupled to components of the oven  10  such as the heating element  54 , the fan  56  that can be incorporated near or behind the vents  36 , the sensor  58 , the user interface  50 , the cameras  32 ,  38 , and the display  48  to either control these components and/or receive their input for use in controlling the components. 
     The controller  52  can implement a heating cycle selected by the user according to any options selected by the user and provide related information to the user. The controller  52  can also include a central processing unit (CPU)  62  and an associated memory  64  where various operational procedures may be stored. One or more software applications, such as an arrangement of executable commands/instructions may be stored in the memory  64  and executed by the CPU  62  to implement the operational procedures. The controller  52  can be in communication with the cameras  32 ,  38  that the images can be output by the cameras  32 ,  38  and input to the controller  52 . The controller  52  can output the images to the display  48  or another display, such as a mobile device display in order for a user to remotely monitor the contents being cooked. It is also contemplated that the cameras  32 ,  38  can also include a separate controller  43 , CPU  44 , and memory  45  dedicated to the cameras  32 ,  38 , as well as the display  48 . The controller  52  can be in communication with a network  66 , such as the internet. The network  66  can include wired, wireless, or a combination of wired and wireless points or nodes to connect communication paths for exchanging and transporting data. Thus, the images from the camera  38  can be sent to a mobile device via the network  66  from the controller  52 . The cameras  32 ,  38  can be directly coupled to the controller  52  or indirectly coupled to the controller  52  via the network  66 . 
     The cameras  32 ,  38  or controller  52  can include an image recognition algorithm that can be implemented as a program in the controller  52  for measuring or recording items within the oven  10  and interpreting information related to such items, such as size, type, or position. The image recognition algorithm can also decide to discard images such as blurry images that are output by the camera  38  or provide unsuitable data as requested by the controller  52 . 
     Referring to  FIG. 4 , the oven  10  can include one or more racks  70 , shown as two exemplary racks  70 . The racks  70 , as well as the rest of the interior surfaces of the oven  10  facing the interior  22  can be colored or coated to have a color that will reduce, minimize, or eliminate visual interference with the transparent, touchscreen display  48 . In one example, the interior  22  and the racks  70  can be white or an off-white, such as a cream color, and made of a ceramic material or porcelain material to withstand the higher temperatures of the oven  10 . Furthermore, additional paneling or cladding can be provide along the interior of the oven  10 , forming or overlying the interior walls having the coloring or coating to backlight the display and minimize visual interference. As the display  48  is the transparent, touchscreen display, it should be understood that different interior colorations and food items can interfere with or obscure the transparent user interface  50 , and particular color schemes can be utilized to minimize, reduce, or eliminate any potential interference when viewing the user interface  50  with the door  30  in the closed position. Alternatively, it is contemplated that the interior  22  can include a particular pattern, which can be used by the camera  32  and the controller  52  to distinguish portions of the oven from food items, to defining a portion of a food recognition system. 
     The internal camera  32  can also be used to detect the racks  70  or the position, such as height or level, of the racks  70 . Such a determination can be used by the oven  10  to recommend a proper cooking position for the racks  70  to a user. 
     Referring now to  FIG. 5 , another exemplary oven  80  is shown, which can be substantially similar to the oven  10  described in  FIGS. 1-4 . A lighting gasket  82  is provided around an opening  84  of the oven  80  for sealing an oven door  86  when moved into a closed position. The lighting gasket  82  can provide for illuminating the cooking chamber within the oven  80  to backlight a display  94  on the door  86 , or can be used to directly lighting the display  94 . Referring to  FIG. 6 , showing a section view of the door  86  in a closed position, the door  86  is provided in the closed position and the gasket  82  is sandwiched between the door  86  and a chassis  88 . The gasket  82  can be made of a flexible sealing element capable of withstanding the heightened temperatures of the oven  80 , such as a Kevlar or a high temperature polymer. 
     A light  90  can be provided in the lighting gasket  82 . The light  90  can be an elongated light strip, for example, extending along the entirety of the gasket  82 . The light  90  can be used to illuminate and light a transparent, touchscreen display user interface  92  on the door  86  at the display  94 . Such a light  90  can provide for suitably illuminating the user interface  92  without excessively illuminating the remainder of the interior of the oven  80  or items contained therein, such as a rack or food items. In this way, the user interface  92  is suitably lit for operation of the transparent, touchscreen display, without excessively lighting the interior of the oven  80 , which reduces any undesirable interference with the user interface  92 . In this way, the user interface  92  is well lit for interaction by a user without visual interference or impairment from the remainder of the interior of the oven  80 . 
       FIG. 7  is an exploded view of another alternative oven  100  with a chassis  102  defining an access opening  104 . A door  106  can be pivotably mounted to the chassis  102 , while shown in  FIG. 7  exploded from the chassis  102 . The door  106  can include an inner frame  108 , an inner glass  110 , an outer frame  96 , and outer glass  98 , and a transparent touch screen  94  applied to the outer glass  98 . The outer frame  96 , outer glass  98 , and transparent touch screen  94  can form a display  112  including a transparent, touchscreen user interface  114 . The inner glass  110  can couple to the inner frame  108  and the outer glass  98  can couple to the outer frame  96 . Furthermore, the outer frame  96  can couple to the inner frame  108  to form the door  106 . The inner frame  108  and inner glass  110  can separate the display  112  from an interior  118  of the oven  100 , shielding the display  112  from the heightened temperatures of the oven  100 . Additionally, a mask  120  can be provided on the inner frame  108  to hide electrical components connected to the user interface  114  for powering and communicating with the user interface  114 . One or more gaps  122  can be formed in the mask  120 , shown as an exemplary four gaps  122 . 
       FIG. 8  shows a front view of the inner frame  108 , having the inner frame  108  removed for clarity. A set of lights  124  or illumination elements can be provided on the inner frame  108  at the gaps  122 . The lights  124  can be used to backlight-illuminate the display  112  of the outer glass  98  and the transparent touch screen  94 , without passing the light through the inner glass  110 . More specifically, the light emitted from the lights  124  can be used to backlight the display  112  without passing through the inner glass  110 , which can be come dirty through use of the oven, which may obscure the display  112 . Electrical connections  126  can be provided on the inner frame  108  along the mask  120  to hide the electrical connections  126  from view when the door  106  is in the opened position. The electrical connections  126  can also be used to electrically and communicatively couple the display  112  and user interface  114  of the inner frame  108  to the remainder of the oven  100 . 
       FIG. 9  shows a section view of the door  106 , having the inner frame  108  coupled to the outer frame  96  with a mount  128 . One light  124  is visible coupled to the inner frame  108 . The light  124  can further include a light module  130 , such as a light emitting diode (LED) or other suitable light source. Additionally, the light  124  can include a heat sink  132  and a lens  134 . The light  124  can be used to illuminate the display  112  and the user interface  114 , without excessively lighting the interior of the remainder of the oven  100 . In this way, the lights  124  can suitably illuminate the transparent, touchscreen display  112 , while reducing or minimizing visual impairment of the display  112  cause by items within the interior  118  of the oven  100  or dirt provided on the inner glass  110 . Furthermore, it is contemplated that a vacuum can be created between the inner frame  108  and the outer frame  96 . Such a vacuum can provide for minimizing heat transfer to the display  112 . 
     In another example, there can be frosting provided on the inner glass  110 . The frosting can provide for minimizing light passed to the interior of the oven  100 , while sufficiently backlighting the display  112 . Alternatively, it is contemplated that the display  112  can be a transparent, touchscreen display having transparent LEDs or OLEDs, which can provide for direct illumination of the display  112 , without requiring suitable backlighting illumination. 
     In yet another example, an optional light diffuser  139 , shown in dashed line, can be provided between the inner frame  108  and the outer frame  96 . The light diffuser  139  can provide for diffusing light from the light  124  to the display  112 . Additionally, the light diffuser  139  can provide for hiding the light from view from a user through the transparent, touchscreen display  112 . 
       FIG. 10  shows an alternative arrangement for the light arrangement within the inner frame  108 , and is looking at the front side of the inner frame  108 , opposite the side facing the interior of the oven.  FIG. 10  can be substantially similar to  FIG. 8 , and therefore the same numerals will be used to describe the same elements, and the discussion will be limited to the differences between the two. A set of LEDs  136 , shown as two LEDs  136 , can be provided behind the mask  120 , such that the mask  120  separates the LEDs from directly lighting the interior of the oven, but rather illuminates the door. A light guide  138  can be connected to the LEDs  136  for spreading light around the door  106  to backlight illuminate the display  112 . The light guides  138  provide for consistently illuminating the display from the LEDs  136  hidden behind the mask  120 , while minimally lighting the interior of the oven. 
       FIG. 11  shows an exemplary display assembly  400 , which can be used as the display in any appliance, oven, door, or other suitable display item or any item described herein which can utilize a display. The display assembly  400  can include a display  402  for displaying a desired image, color, opacity, or combination thereof. For example, the display  402  could depict a recipe or a food item requested by a user. In another example, the display  402  could be completely transparent, permitting a user to view the interior of the appliance. Thus, it should be appreciated that the display  402  can provide for displaying any information, or lack thereof, and can be completely or partially transparent. The display  402  can also locally or discretely change what is displayed, and need not be common among the entirety of the display  402 . 
     The display  402  can be contained within a frame  404 . The frame  404  can be used to hold the display  402 , as well as mount the display  402  to the remainder of the door or appliance to which it attaches. The frame  404  can includes a set of extensions  406  having fastener openings  408  for mounting the frame  404  to a door or appliance, for example. 
     A connection assembly  408  can extend from a portion of the frame  404 . The connection assembly  408  can include a housing  410 , which can contain a printed circuit board (PCB)  414  as well as other electrical components. The PCB  414  can be operably coupled to the display  402 , providing for controlling operation of the display  402 . The PCB  414  can also provide for electrically and communicatively connecting the display assembly  400  to the rest of the appliance within which the display assembly  400  is mounted. 
       FIG. 12  shows an exploded view of the display assembly  400 , better illustrating the additional components included within the assembly  400 . The display assembly  400  includes the display  402  as well as the frame  404 , but also can include a light source  420 , light glass  422 , a first gasket assembly  424 , and a second gasket assembly  426 . 
     The frame  404  can be separated into a frame cover  430  and a frame base  432 , which can collectively adjoin to form the frame  404 , and contain the light source  420 , the light glass  422 , the first gasket  424 , and the display  402 . In one example, one or more of the extensions  406  can be used to fasten the frame cover  430  to the frame base  432  with one or more fasteners. The frame  404 , as well as the frame cover  430  and the frame base  432 , can be made of a material capable of withstanding high temperatures, such as those more than 110 degrees Fahrenheit. Suitable materials can include thermally resistant plastic or Aluminum, while a number of materials would be suitable. 
     The light source  420  can be any suitable light source for illuminating the light glass  422  and the display  402 . In one example, the light source  420  can be provided as a pair of light emitting diode (LED) sources, formed as strips. In another example, the light source  420  can be formed as an LED source provided on an Aluminum substrate. The light sources  420  are shown as provided on the sides of the light glass  422  and the display  402 , while any suitable positioning is contemplated. Ideally, the positioning and light source  420  is one that suitably lights the display  402 , without providing excessive backlighting, or preventing or hindering transparency of the display  402  when desired. It should be also appreciated that the LED orientation and placement can have an impact on display quality of the display  402 . Therefore, while the exploded view shows that the light sources  420  are provided as a pair of LEDs on strips, it is also contemplated that the light sources  420  can be arranged on any one or more of either lateral side, the top, the bottom, or any combination thereof. Additionally, the LEDs can have a power between 1200 lumen to 3600 lumen, while other powers are contemplated. 
     The light sources  420  can be electrically and operably coupled to the PCB  414  for powering and controlling operation of the light sources  420 . For example, electrical connections can connect the light sources  420  to the PCB  414 , which can be hidden within the frame  404  when the assembly is completed. The PCB  414  or components thereof can control the power provided to one or more of the light sources  420 , which can be varied to change the level of transparency or opacity for the display  402 . 
     The light glass  422  provides for backlighting the display  402  with the light source  420 . The light glass  422  can be thin, having a thickness between two millimeters (mm) and six mm. It should be appreciated that greater or lesser thicknesses may be used, but can have an impact on display quality the further the thickness varies from between two mm to six mm. For example, variation from the 2 mm-6 mm range may have a negative impact on the transparency or display quality for the display assembly  400 . 
     The first gasket assembly  424  can be provided between the light glass  422  and the display  402 . The first gasket assembly  424  is formed as a combination of individual gaskets, providing space for portions of the connection assembly  408  mounted to the display  402 . The first gasket assembly  424  provides for sealing the spaced between the display  402  and the light glass  422 , preventing dust or other matter from entering between the two, which could otherwise distort or tarnish the display  402 . 
     The second gasket assembly  426  can be provided between the frame  402  and a touch panel  444  (not shown in  FIG. 12 , see  FIG. 13 ). The second gasket assembly  426  can serve a purpose similar to that of the first gasket assembly  424 , except that the second gasket assembly  426  seals the opposite side of the display  402  which is adjacent the touch panel  444 . 
       FIG. 13  shows an exploded view of a door assembly  440 , incorporating the display assembly  400  of  FIGS. 11-12 . The door assembly  440  includes a front door structure  442  that can include a touch panel  444  forming the front glass of the door structure  442 . Additionally, one or more components can be included with the front door structure  442 . While only a PCB  446  is shown, any suitable controller can be utilized to transmit information from the touch panel  444  to the remainder of the door assembly  440 . The display assembly  400  can couple to the front door structure  442 , such that the touch panel  444  is provided in front of the display  402 , such that the user can interact with the display  402  via touching the touch panel  444 , while not directly interacting with the display  402 . In this way, the display  402  can be protected to resist or minimize potential damage, as well as improve overall lifetime. 
     The door assembly  440  further includes a thermal cover assembly  448 , which can include a thermal glass  450  mounted between a pair of frame rails  452 . The thermal cover assembly  448  can be transparent, permitting viewing into the interior of the appliance to which the door assembly  440  mounts. The thermal cover assembly  448  provides at least some thermal protection for the display assembly  400 , such that heightened temperatures do not negatively impact operation of the display assembly  400 , and that the touch panel  444  does not excessively heat. 
     An inner glass door assembly  460  is provided at the interior-most portion of the door assembly  440 , relative to an interior of the appliance upon which the door assembly  400  is mounted. The inner glass assembly  460  is the first shield against the heated environment interior of the appliance, and should be made of a material capable of withstanding heightened temperatures, such as those during operation of an oven, for example. 
     A pair of rail covers  462  are provided for securing the door assembly  440  together at the sides. Additionally, a top rail  464  can be provided with the inner glass door assembly  460 , which can be used to secure and cover the door assembly  440  at the top and adjoin to the rail covers  462 . 
     The door assembly  440 , as well as the display assembly  400  contained therein, provides for a touch-enabled door assembly with a display, permitting the user to interact with the appliance to which the door assembly  440  attaches. Additionally, the display assembly  400  provides for a determinative transparency or opacity for the display  402 , permitting the user to view the user interface on the display  402 , or view the interior of the appliance through the display  402 . Additionally, the door assembly  440  provides for integrating the user interface into the door of the appliance, while utilizing a user interface that can be selectively shown or transparent on the door. Furthermore, the door assembly  440  including the thermal glass  450  provides for suitable temperature distribution to prevent overheating or damage of the display assembly  400 . 
       FIG. 14  shows a front perspective view of another exemplary oven  140 . The oven  140  includes a chassis  142  to define an interior  144 . A door  146  can move between an opened position and a closed position, as shown, selectively opening and closing the interior  144 . The door  146  further includes a display  148  with a transparent, touchscreen user interface  150 . The chassis  142  further includes an upper panel  152  positioned above the door  146 . 
     A camera  154  is provided on the upper panel  152  and faces outwardly towards a user using the user interface  150 . The camera  154  can be used by the user to interact with the oven  140  and the user interface  150 , as well as facilitating use of the user interface  150 . In this way, the camera  154  can complement use of the transparent, touchscreen display  148 . While the camera  154  is shown on the upper panel  152 , other positions are contemplated for the upper panel  152 . Non-limiting examples can include the bottom of the user interface, or below the handle on the door. 
       FIG. 15  includes a user  156  viewing the oven  140 , and the camera  154  can sense, record, or otherwise image the user viewing the over  140 . Additionally, a separate camera  160  can be provided on the oven  140  for imaging the interior of the oven  140 , such as imaging a food item contained therein. The user interface  150  depicts a food item  158  contained within the oven  140 . It should be appreciated that the food item  158  is both contained in the oven  140 , at least partially hidden from view through the transparent, touchscreen display  148 , and displayed as an image on the display  148 . The image of the food item  158  can be a three-dimensional representation of an actual food item, imaged by the camera  160  viewing the interior of the oven  140 . In one example, the camera  160  can identify the food item contained within the oven  140 , generating its own three-dimensional image of the food item. Alternatively, it is contemplated that the user can input the particular food item, which can be provided to the oven  140 , such as from a database. Using the identification of the food item within the oven, the display  148  can generate an image of the food item. 
     As the user  156  is positioned on the left side of the oven  140 , the camera  154  on the upper panel  152  can take an image and record a position of the user  156 . The image of the food item  158  presented on the display  148  can be shown from the left side, as imaged by the interior camera  160 , reflecting the proper vantage for the user for a virtual representation of the food item  158 . 
     Referring now to  FIG. 16 , the user  156  is now moved to the right side of the oven  140 . The changed position of the user  156  can be measured and recorded by the camera  154  on the upper panel  152 . Based upon the right-side position of the user  156 , the three-dimensional representation of the food item  158  has now been virtually rotated to properly reflect the vantage point of the user  156 , which can be recorded and generated by the camera  160  viewing the interior of the oven  140 . 
     Therefore, it should be appreciated that the camera  154  on the upper panel  152  can be used to determine a local position of the user  156  relative to the oven  140 . Such a measurement can be used to record a food item within the oven  140  and generate a three-dimensional representation on the display  148  reflective of the position of the user  156 . In this way, the image provided on the display  148  can provide for the user viewing the food item within the oven  140 , which may otherwise become obscured by the transparent, touchscreen display  148 . Furthermore, it should be appreciated that the generated image of the food item  158  can be rotatable as a three-dimensional representation, based upon position or movement of the user to adjust for the parallax imaging of the food item within the oven  140 . Such an image recorded by the camera  160  and provided to the display  148  can be done in real time based upon movement and location of the user recorded by the camera  154 . Additionally, the user need not change the position of where they are standing, but the camera  154  can detect a user&#39;s eyes or face and can rotate the image of the food item based upon head or eye movement of the user alone. Facial recognition software or eye tracking software can be used by the camera  154  to adjust for the parallax imaging of the food item in real time. 
     In one example, the camera  154  can focus on the user&#39;s eyes to track the position of the user  156 . More specifically, the camera  154  can include or be operably coupled to a processor including an eye-tracking algorithm to identify and track the position of the user&#39;s eyes via the camera  154 . As the user  156  moves, the camera  154  can track the position of the user  156  based upon the movement of the user&#39;s eyes. As the user moves laterally or side-to-side, the camera  154  can track the user&#39;s eyes and rotate the displayed image of the food item  158  to adjust for parallax of the image based upon the position of the user  156 . In another example, the camera  154  can use facial recognition software to determine the position and distance of the user from the oven  140 . Generally, it should be appreciated that the camera  154  can be used to record or image a user, and software in the controller can utilize the image to real-time determine the position and movement of the user. 
     Referring now to  FIG. 17 , an alternative representation for the parallax compensation for the oven  140  is shown, to facilitate understanding of the concept. As the user  156  moves left or right, depicted by arrows and broken lines for the user  156 , the front camera  154  can record and image the movement of the user  156 . The oven  140  can provide for displaying the food item  158  in a rotated, three-dimensional position, based upon the position of the user, to adjust for parallax. In this way, the user  156  is permitted to view the sides of the food item  158  as well, and inspect how the cooking process is going without opening the oven  140  to inspect the food item  158 . 
     It should be appreciated that the image of the food item  158  can be adjusted based upon the position of the user. For example, the lateral position of the user moving side-to-side or left-to-right can rotate, move, or augment the image of the food item  158  so the user can inspect different portions of the food item based upon the movement of the user as measured by the camera  154 . In another example, the image of the food item  158  can be sized based upon a distance of the user from the oven  140  as measured by the camera  154 . As the user moves closer to the oven  140 , the image can be enlarged to facilitate inspection of the food item  158 , while the food item can become smaller or shrink as the user moves away from the oven  140 . 
     Referring to  FIG. 18 , another exemplary oven  180  includes a chassis  182  defining an interior  184 . A door  186  is movable between and opened position and a closed position, as shown, selectively providing access to the interior  184 . A transparent, touchscreen display user interface  188  is provided on the door  186 , with the user interface  188  permitting a user to interact with and operate the oven  180 . 
     The user interface  188  can include a control portion  190  and a viewing portion  192 . The control portion  190  can include one or more elements facilitating interaction with and control of the oven  180 . Exemplary elements can include touch buttons  191 , an information pane  194 , a timer  196 , as well as other operation controls for the oven  180 . The viewing portion  192  can provide for viewing a food item  198  within the oven  180 . In one example, the viewing portion  192  can be transparent, permitting viewing of the food item  198  within the oven  180  via the transparent display user interface  188 . Alternatively, the viewing portion  192  can generate an image of the food item  198 , as recorded by an interior camera  200  imaging the food item  198 . Furthermore, it is contemplated that the user interface  188  can show a time-lapsed video of the food, or as a series of images, to illustrate how the food has changed over time as it is cooked. 
     Referring to  FIG. 19 , the positions of the control portion  190  and the viewing portion  192  have been switched as compared with that of  FIG. 18 . The switched position of the portions  190 ,  192  provides for viewing the food item  198  from an alternative position. Such a position for the control portion  190  and the viewing portion  192  can be determined, for example, by a position of a user. The position of the user can be measured by a second camera  202  provided on the front of the oven  180 . The oven  180  can vary the position of the control portion  190  and the viewing portion  192 , based upon the position of the user to facilitate viewing of the food item  198 . Furthermore, the image of the food item  198  presented on the viewing portion  192  can be rotatable, similar to that described in  FIGS. 15-16 , adjusting for the parallax as the user views the food item  198  being represented in the differing positions of the viewing portion  192 . 
     Referring to  FIG. 20  shows the oven  180  with the user interface  188  as fully or near-fully transparent, providing for viewing the food item  198  within the interior of the oven  180  through the user interface  188 . Alternatively, it is contemplated that the user interface  188  can be fully covering the display on the door  186 , displaying a virtual reality or augmented reality image of the food item  198  on the full user interface  188 . 
     Referring to  FIG. 21 , the user interface  188  on the oven  180  can be wholly opaque, as controlled by the user interface  188 . The opaque user interface  188  can hide the interior of the oven  180 , providing for an appealing user aesthetic when the oven is not in use or in the middle of operation when inspection by the user is not needed. In one example, the camera  202  can be used to detect the user having a distance from the oven  180 . The opacity for the user interface  188  can be adjusted based upon the distance of the user as measured by the camera  202 . For example, as the user moves nearer to the oven  180 , the opacity can decrease. As the user moves further from the oven  180 , the opacity can increase. Such a variable opacity can provide for a desirable aesthetic while the user is not interacting with the oven  180 , but can activate as the user nears the oven  180 , enabling interaction with the oven  180  as the user approaches the oven  180 . As the user nears the oven  180  and the opacity decreases, the transparent portion of the user interface can provide a view of the interior of the oven  180 , or the control portion of the user interface can become visible, such as those described in  FIGS. 18 and 19 . 
     Regarding  FIGS. 18-21 , it should be appreciated that the user interface  188  provides for multiple operational modes for the oven  180 . Specifically, an opaque mode, shown in  FIG. 21 , a transparent mode, shown in  FIG. 20 , and a mixed mode, shown in  FIGS. 18 and 19 , can be utilized by the oven  180  to provide a variable set of user experiences through variation with the user interface  188 . The opaque mode can provide for hiding the interior and providing an aesthetic appearance when the oven  180  is not in use. The transparent mode can provide a transparent window for the entirety of the user interface  188 , permitting a full view of the interior of the oven, or a full augmented reality view. Finally, the mixed mode can provide for presenting both a user interface  188  that the user can interact with to control the oven, as well as a transparent portion for viewing the interior of the oven  180 . Furthermore, the user can arrange the user interfaced  188  in the mixed mode, such as with a drag-and-drop format, and can move particular items to facilitate use or viewing of the interior of the oven  180 , such as that illustrated among  FIGS. 18 and 19 . 
     Referring now to  FIG. 22 , oven  180  of  FIGS. 18-21  is shown in the opened position, with the door  186  pivoted downward. The user interface  188  is visible through the transparent, touchscreen display. It should be appreciated that the user interface  188  can be flipped vertically. In this way, the user interface  188  that would be upside-down in the opened position is now oriented upright, permitting the user to view the user interface  188  when the door  186  is opened. It is further contemplated that it is possible to have a second touch surface permitting the user to interact with the user interface  188  in the opened position on the interior of the door  186 . 
     Referring now to  FIG. 23 , which can be substantially similar to  FIG. 22 , shows a door  186   b  in the opened position that can opened in a sideways or side-to-side manner, pivoting about the chassis  182   b  along a sidewall. The user interface  188   b  can be flipped horizontally, such that the user interacting with the oven  180   b  can properly view the information displayed on the user interface  188   b  through the transparent display. Additionally, it is contemplated that the door may have a second touch surface to interact with the door on the interior of the door  186   b.    
     Referring to  FIG. 24 , another exemplary oven  220  is shown including a chassis  222  with a door  224 . A transparent, touchscreen display  226  is provided on the door  224  for viewing the interior of the oven  220  and interacting with and controlling the oven  220 . A camera  228  can be provided on the chassis  222  for viewing and imaging the interior of the oven  220 . The camera  228  can be used to determine a position of a rack  230  provided within the oven  220 . The display  226  can display a representation of the rack  230  at the current position. Additionally, the display  226  can display a suggested position for the rack  232 . Such a suggested position can be based on a current food item  234 , such as a pie as shown. For example, a food item  234  provided to near or far from the center of the oven can provide or increased cooking near the center of the oven and decreased cooking further from the center of the oven, resulting in an uneven cook of the food item  234 . In another example, a pie closer to the bottom of the oven will brown the bottom of the pie faster from the radiant heat, while a position closer to the top can brown the top faster. Where an optimal cooking position for the food item  234  is at a position different than that of the current position of the rack  230 , the display  226  can present a virtual optimal position for cooking the item via the suggested position for the rack  232 , depicted with virtual arrows  236  suggesting moving the rack to another position. Additionally, it is contemplated that a position of the food item at the correct height can be displayed on the display  226 , and the user can adjust the height of the rack to arrange the food item  234  at the correct height based upon the image on the display  226 . Therefore, the transparent, touchscreen display  226  can work in concert with the camera  228  to determine the current position and suggest another position for a rack  230 . In this way, the oven  220  can provide for optimizing cooking of the food item  234  by suggesting a different cooking position. 
     Referring to  FIG. 25 , the oven  220  can also use the camera  228  to determine a position of the food item  234  within the oven  220 . The display  226  can be used to suggest a different cooking position for the food item  234 , in order to prevent obscuring of a second food item  248 . As shown, the food item  234  is provided toward a right side of the oven  220  on a top rack  230 . The camera  228  is at least partially obscured from viewing the second food item  248 . The display  226  can suggest an alternate cooking position, represented in broken line as a suggested position  238  by an arrow  240 , in order to view and image both food items within the oven  180 , so a user can inspect either food item within the oven without requiring opening of the oven door  224 . 
     Therefore, the oven  220  can use the camera  228  to determine a position of a food item  234  and suggest an alternative position  238 . Such a recommendation can alternatively provide for an alternative optimal cooking position, providing for even cooking of the food item, which can improve a user experience with the oven  220 . 
     Referring now to  FIG. 26 , the oven  220  can further suggest an optimal position for a food probe  242 . For example, the food item  234  is shown as a turkey, which can cook unevenly. Inserting the food probe  242  into the turkey as an optimal position  244  can ensure that the food item  234  is fully cooked before removal. The optimal position  244 , showing the probe in broken line, can be represented on the display  226 . In  FIG. 27 , the food probe  242  can be shown on the display, while the food item  234  is visible to a user through a transparent portion of the transparent display  226 . Such a representation facilitates proper positioning of the food probe by the user to ensure proper cooking of the food item  234  after the food probe has been inserted. 
     The camera  228  can also image and determine a current position of the probe  242  within the food item  234 . The display  226  can display an alternative food probe position  246 , which can be an optimal position for the food probe  242 . This ensures proper cooking of the food item  234  via temperature measurements by the probe  242 . In this way, the oven  220  can provide for improved cooking of a food item  234 , resulting in a better user experience with the oven. 
     Referring to  FIG. 28 , an example user interface  260  for an oven  262  can be provided on a transparent, touchscreen display  264 . The user interface  260  includes one or more elements, which can be displayed to a user or can be interacted with by a user. The elements include a menu bar  266 , an items number bar  268 , and a list of items  270 . The menu bar  266  can be used with the user interface  260  to select the current format of the user interface  260 , shown as a meal coordination display. The list of items  270  can include a drop-down menu or an interactive feature permitting a user to enter the particular food items to be cooked. In one example, selecting the items  270  can open a keyboard for a user to enter the particular food item. Additionally, the list of items  270  can each include a cook time  272  and a cook temperature  274 . The cook time  272  and cook temperature  274  can be input by the user as optimal cooking information particular to the food item. In another example, the oven  262  can import optimal cook times and temperatures for the particular food items, such as from a database connected to the oven  262 . 
     As shown, a first item  276  has a cook time  278  of twenty-two minutes, at a cook temperature  280  of 350-degrees. A second item  282  has a cook time  284  of 9 minutes and a cook temperature  286  of 375-degrees. A third item  288  has a cook time  290  of thirteen minutes and a cook temperature  292  of 325-degrees. The user interface  260  can provide for coordinating cooking all three items  276 ,  282 ,  288  within the same oven, to provide optimal cooking for multiple items at differing cook times and temperatures. Each cook time and temperature can be input by the user, while it is also contemplated that the oven  262  can retrieve the cook times and temperatures from a remote database, such as over the internet. Furthermore, while not depicted, the oven  262  can suggest optimal cook positions for each food item, similar to that as described in  FIG. 13 . 
     Referring to  FIG. 29 , after the cooking coordination has been entered by the user, as shown in  FIG. 28 , the display  264  can depict information related to the coordination of multiple food elements, as well as providing a transparent portion  294  for viewing the food items  276 ,  288 . The display  264  can include an information panel  296  showing the status of the multiple food items  276 ,  282 ,  288 . As can be appreciated the first item  276  had the longest cook time, the second item  282  has the second longest cook time, and the third item  288  has the shortest time. The first item  276  has been placed in the oven  262  and is cooking. The cooking temperature for the oven  262  can be an optimal temperature for cooking the multiple items, shown as 350-degrees as the average cook temperature for all items. Additionally, the cook times for each item can be adjusted based upon the change in cook time to ensure proper cooking of the items among a range of temperatures. 
     The first item  276  can include a status bar  298  as well as a time  300 , showing the current completion of the first item  276 . Similarly, the second item  282  can include a status bar  302  and a time  304 . Finally, as the third item  288  has not yet been placed in the oven, but can still include a status bar  306  as well as a timer indicating how much time until it is to be placed in the oven  262 . Additionally, the system can be programmed to detect when the oven is or has been opened, and can updated the current cook times based upon detection of a new food item being placed in the oven with the interior camera, or strictly based upon opening or closing of the oven. Furthermore, the oven  262  can suggest a particular position for each food item within the oven  262  in order to provide the best cooking position for each individual food item. In one example, the oven  262  can suggest moving one food item as additional food items are added. 
     Therefore, it should be appreciated that the user can enter basic cooking information such as cook times and temperatures, and the user interface  260  can provide for automatically coordinating cooking of the multiple items to ensure optimal cooking of multiple items within the single oven  262 . Similarly, it is contemplated that the user interface  260  can instruct the user of the optimal cooking positions, which may change as more cooking items are added or removed. Furthermore, it is contemplated that the oven can consider rest times for food items, which may need to rest after cooking, while additional items continue to cook. This can ensure that all items are optimally cooked, and that a full meal with multiple items can be completed at the same time, utilizing the single oven  262 . 
     Referring to  FIG. 30 , another exemplary oven  330  leverages a camera  332  to intelligently push an image  334  of a food item  336  to a user&#39;s mobile device  338  or an oven&#39;s display  340 , such as a transparent, touchscreen display, at one or more event-triggered intervals  342 . Event-triggered intervals  342  can include event triggers such as time-based intervals  342   a , temperature-based intervals  342   b , “doneness” based intervals  342   c , cooking cycle events  342   d , or other intervals that can occur during the cooking process. At the event-triggered interval  342 , an oven&#39;s electronic system  344  pushes the image  334  of the food item  336  over a network  350  to the user&#39;s mobile device  338  such as a smart phone or tablet or to the oven&#39;s display  340  thereby allowing the user to visually inspect the food items&#39;  336  current status. 
     Additionally, it is contemplated that the oven  330 , or any oven described herein, can be in communication with a recipe database or a food identification database, or both, or any other database for sending or retrieving information related to the oven  330  or operation thereof. The recipe database can be integrated with a user interface  352  provided on the display  340  to display a recipe or portions thereof to the user, guiding through the preparing and cooking of a food item or an entire meal. Additionally, it is contemplated that the oven  330  can be in communication with a food ordering or delivery service to deliver ingredients of the recipe to the user, controlled at the user interface  352 . The food identification database can be incorporated through images taken at the camera  332 , where such recorded images can be compared and analyzed against a database to identify the food item within the oven  330 . Based upon identification, additional meal items, wines, or other pairings can be suggested at the user interface  352 . More specifically, such recipe or food identification can be integrated with the transparent touchscreen display for the user interface  352 , providing for viewing and interacting with the display, while optionally viewing the interior of the oven  330  simultaneously. 
     Examples of event-triggered intervals  342  can be any interval pre-programmed into the oven&#39;s electronic system  344  or any user-defined interval. In one non-limiting embodiment, an event-triggered interval  342  can be a time-based interval  342   a  such as specific time remaining in a cooking program such as when a cooking program has 2 minutes of time remaining. Another example of a time-based interval  342   a  might be pushing an image  334  every 5 or 10 minutes during a cooking cycle. The interval could be longer or shorter based on the cooking cycle programmed time, or, the interval or set point could be input by the user. At each event-triggered interval  342 , the camera  332  can be triggered by the electronic system  344  to send the user an image  334 . 
     In another non-limiting example, an event-triggered interval  342  can be a temperature-based interval  342   b  such as when the temperature of the food item  336  reaches a certain temperature or falls within a predetermined range. In this example, a sensor such as a temperature probe  346  can be inserted into the food item  336  for measuring the temperature of the food item  336 . The temperature probe  346  can be in communication with the oven&#39;s electronic system  344  and when the electronic system  344  detects that the temperature of the food item is within, for example, 25 degrees of a predetermined target temperature, the event-triggered interval  342  can be triggered. The temperature degree interval could be longer or shorter, or, could be an interval input by the user. Another temperature-based interval  342   b  might be pushing an image  334  to a user&#39;s mobile device  338  at increments of 5 or 10 degrees during a cooking cycle or at a specific set point. Once again, the interval increments could be longer or shorter, or, the interval increments or set point could be selected by the user. 
     In another non-limiting example, an event-triggered interval  342  can occur at a doneness-based interval  342   c  such as when a level of “brownness” is achieved. For example, certain food items may brown or change color over a cooking cycle. A computing device  348  or controller, for example, in the oven&#39;s electronic system  344  can be programmed with an algorithm that can compare the brownness or color change of a food item with a desired brownness or color level pre-programmed in the electronics system  344 . Once the comparison is made, the computing device  348  can be programmed to transmit an image  334  of the food item  336  at one or various brownness intervals or at intervals of increasing brownness such as every 5 or 10 degrees. In this example, the doneness-based interval can be longer or shorter, or, an interval or set point selected by the user. 
     As should be recognized, while the doneness-based interval  342   c  could be based on “brownness” or “char” of a food item, it could also be based on other indications or measurements of doneness such as internal temperature, humidity, raising of dough, bubbling, crispiness, or other indications. One or more sensors could measure one or more doneness-based indications and the oven&#39;s electronic system  344  could be programmed to trigger an event based on one or more intervals or combinations thereof. 
     In another non-limiting example, an event-triggered interval  342  can occur at a cooking cycle event  342   d  such as when flipping, stirring, mixing, adding a topping, finishing (e.g. turning on the broiler), or any other event that may require user input/interaction. For example, the oven&#39;s electronic system  344  can push an image  334  of the food item  336  to the user&#39;s mobile device  338  when the food item  336  directions require user input or interaction. 
     Such an event-triggered interval  342  can provide for pushing a notification to the mobile device  338 . Alternatively, it is contemplated that the mobile device  338  can be used to request a ‘live look’ or a live image or video of the interior of the oven  330  or the food item  336 , permitting a user to view the food item  336  or interior of the oven  330  on demand while remote from the oven  330 . 
     Referring to  FIG. 31 , another exemplary oven  370  can include a transparent, touchscreen display  372  including an interactive user interface  374 . A camera  376  can be provided on the oven  370  for imaging a food item  378  within the oven  370 . The camera  376  can take or record an image of the food item  378  and provide the image to the display  372 . A user  380  can interact with the transparent, touchscreen display  372  to view the food item  378  via imaging from the camera  376 . In one example, the user can drag the image across the display to view different portions of the food item  378 . The camera  376  can be responsive to actions by the user  380 , to show the food item  378  based upon the interactions of the user  380  with the user interface  374 . 
     Similarly, the user  380  can ‘pinch’ or ‘pull’ the screen in varying directions to zoom into or away from the food item  378 . Such zooming can be recorded by the camera  376  and presented on the user interface  374 . Such zooming features provide for inspection of the food item  378  by the user to check the ‘doneness’ of the food without requiring the user to actually open the oven, while a traditional view of the interior of the oven is not sufficient for checking on the food item  378 . As can be appreciated, the user can zoom in on the turkey food item  378  to enlarge the food item  378  as an enlarged food item  382  to carefully inspect the food item  378  to check for doneness. 
     Additionally, with the description included herein, it is contemplated that a controller or electronics system for an oven can recognize and identify a particular food item within the oven. Such a recognition can be pulled from a database of food items, with the oven connected to the database over a network such as the internet. Additionally, the oven can record images and add to the database, so the database can ‘learn’, improving food identification over time.
