• Delivery of a scene instep540 includes an orchestrated delivery of two or more of the LCD panel display, the projected display, the audio recording, and the object manipulation. When the scene delivery step is completed, afeedback query step542 follows.
• Thefeedback query step542 awaits, for example for a predetermined time, patron action(s) such as responses to the delivered scene and/or questions. To the extent there is such a patron action, the process returns544 to theassessment step520 wherein the patron action is assessed to determine an appropriate response and/or appropriate content responsive to the patron action. To the extent no patron action is recognized as eliciting a response, the process returns543 to the awaittrigger step510.
• Whereassessment520 followsfeedback542, the next step is the first scene query. The answer to the first scene query is No524 where, as here, a first scene was earlier constructed530 and delivered540. When the first scene query is answered, a newscene query step526 follows.
• In the newscene query step526, a determination is made as to whether or not a new scene should be used in a response to the patron action. If answered No527, the response tofeedback step529 follows and a response, other than constructing and delivering a new scene, may be made. If answeredYes528, the next step is theconstruct scene step530. Notably, where a response tofeedback529 is made, the process may return531 to thefeedback query542.
• Construction of a scene instep530 is executed here for a second or subsequent time. Here, the scene constructed is at least in part responsive to the patron action. Scene construction includes one or more of selecting a video scene for display on theLCD panel104, selecting a video scene forprojection457 on a surface other than a display case surface, selecting an audio recording for playback via the amplifier andspeakers461, and selecting a movement of an object within the display case via amanipulator459. When the scene construction step is completed, a deliverscene step540 follows.
• Delivery of a scene instep540 includes an orchestrated delivery of two or more of the LCD panel display, the projected display, the audio recording, and the object manipulation. When the scene delivery step is completed, afeedback query step542 follows.
• The number of times that patron feedback is responded to may be limited. For example, responses may be limited as x responses per time span, y responses per patron, or z responses per product as in z responses per product per hour for example.
