Not to get all Don Norman on the author here, but he really means “signifier” almost everywhere he uses “affordance” — he’s talking about the visibility of these sliders’ use, not what they actually allow (or, “afford”).
- Ygg2 6y agoIf you are going to be pedantical, Norman used affordance as perceived quality. Gibson used affordance as innate quality. E.g. a hidden door has no affordance according to Norman. Gibson on the other hand, considers doors ability to be opened its affordance. I think article usage is on point for Norman's definition.
- zamfi 6y agoYay, a pedantic-off! You're right that a hidden door has no affordance, according to Norman (though others have claimed "hidden" affordances). However, I'm referring to the author's statements like these: > There is no static affordance showing you what you can do [...] What's missing, the "static <thing>" is not an affordance, it's the signifier -- an indicator that the action is possible.
