Yet, in another embodiment of the disclosure, generally, the interaction designer may define named views and then associate each superimposed/overlaid widget to one or more of said named views through an attribute provided on the widget for defining such associations such that, at job performance time, the user of the IPT 702 is able to switch to different views, where each selected view only displays the content of the widgets associated to said view.
Yet, in another embodiment of the disclosure, generally, the interaction designer can divide the digitized document into two parts: 1) Front Matter (usually containing sections such as Purpose, Scope, Responsibilities, Precautions and Limitations, and Prerequisites) vs Body (usually containing the procedure or instructions). And then require the person performing the job, at job performance time, to acknowledge the Front Matter before he/she may proceed to the Body. Alternatively, the IAT 402 may provide a widget designed to contain multiple sections of the digitized document, say Section widget, in this case containing all the sections of the Front Matter, and turn on the acknowledgment interaction for that widget and link it to the first widget of the Body.
