Abstract
We originally studied affordances to design products that encourage resource-efficient behavior in users. This paper was motivated by the observation that a lack of resources affected the ability of impoverished slum residents to perceive affordances. Data gathered from a trip to Bangladesh support recent postulations that affordance perception depends on user intention and socio-cultural norms, which are also influenced by fixation and training. We thus became interested in how absence, whether of material, components, or entire products, affected the utility of objects. We describe three dimensions of absence, one major and two minor. The major dimension is used to express the range of physical absence, i.e., of material in a part, of a part in a product, and of the entire product. Minor dimensions include the extent of user control and the permanence of absence, each of which can be used to increase utility in objects. We provide existing examples along these dimensions and describe concepts along the major, physical dimension of absence. We propose that the affordance of absence can be used as an approach to identify novel affordances, and conclude by placing it in the context of existing affordance-based design methods.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
