Yet, another embodiment of the disclosure relates, generally, to a Data Interface Widget for simple data entry by the user, without being tied to the inputs/outputs of a software service. The Data Interface widget may be superimposed/overlaid on any part of a content block that is already contained within any other widget and the data entered through such widget is made available throughout the interactive instruction/procedure/form to be referenced by all widgets with sequence numbers greater than the sequence number of the Data Interface Widget or its containing widget. Furthermore, the users of IAT 402 and IPT 702 may enter constants in interface widgets to support computation (ex min/max values). The location of a Data Interface Widget is saved relative to its containing widget just as with other interaction or interface sub-widgets.
