One of my ongoing interests is visualizing the field of affordances. See for instance the Trusted Subcultures-project RAAAF presented at the Sao Paulo Biennale 2009, using social affordances to create new public domain for the centuries old water city of Amsterdam. Or, more recently, our project Outstanding Landscape of Affordances.
Another example is the Dutch Atlas of Vacancy in which we investigated the affordances (in context) of 10.000 empty public builldings in the Netherlands. For instance the possibilities for making noise: at a vacant air base or in a vacant bunker one can make sounds of 140DB without disturbing anyone.
In a new special issue on Neurophenomenology edited by Evan Thompson for Frontiers, Sanneke de Haan, Martin Stokhof, Damiaan Denys and I have now published a more abstract sketch of different fields of affordances.

We propose that the changed world as described by the 18 OCD patients with Deep Brain Stimulation interviewed by us at the Academic Medical Center can be fleshed out in terms of changes in their field of relevant affordances. We can distinguish three dimensions to this field: the “width” refers to the broadness of the scope of affordances that one perceives. This dimension relates to having a choice or action options. The “depth” of the field refers to the temporal aspect: one not only perceives the affordances that are immediately present here and now, but one is also pre-reflectively aware of future plans and possibilities for action: the affordances on the horizon that one is responsive to, so to speak. This temporal horizon reflects our anticipatory affordance-responsiveness. Lastly, the “height” of each of the affordances refers to the relevance or importance of the affordances that one is responsive to, i.e., to the experienced solicitation or affective allure. This dimension of relevance and salience relates to the motivational force of affordances.
The title of our (open access) article is: The phenomenology of deep brain stimulation-induced changes in OCD: An enactive affordance-based model.
