Depicting the Affordance Gap, (Functional Fixedness) (Hegemony?) Re Water as a resource

This is an attempt to depict what I call an 'affordance gap', (Re Norman) as the already identified  designed objects percieved affordance may shutter out certain natural affordances, the example here being water suppy,  perhaps bottled water would have been a better example focus , those sources shuttered out from the central initial focus (home tap, and assumed function, in this case identified as ' controlling water flow'), may include public water fountains for example or water containing plants...our knowledge restricted perhaps by the historical norms or the market (in the example of bottled water) I mention the "travel tap' here a portable water filtering system that lets you drink from streams and lakes
It seems to me that aspects of   'Hegemony' (Gramsci) could potentially also be depicted in this way


The depiction utilizes a 'contextualizer'
A software system I have designed that offers a semi structured space for people to find their way through communication issues (and design issues) encouraging when appropriate compilmentary solutions

whiteboards v iPads

hegemony: tap water - rain collection fountain etc

tv  - inner visualisation
information - intuition
