This article introduces a new affordance framework for humans and human design. Based on previous important concepts in product design-affordance, signifier, and product semantics, the authors propose three new concepts to illustrate how people perceive affordance. According to the model, perceptual probability of affordance is the probability that the public can perceive a certain affordance; perceptual threshold of affordance is the threshold at which affordance can be perceived by a person and changed by perceptual information; and situations, in which interactions between affordances and people exist, are crucial influences on human-affordance interactions. An illustration of the model and suggestions for further research are provided.
本文介绍了一种适用于人类与人类设计的新可供性框架。基于产品设计中先前的重要概念——可供性、指示符和产品语义学，作者提出了三个新概念，以说明人们如何感知可供性。根据该模型，可供性的感知概率是公众能够感知到某种可供性的概率；可供性的感知阈值是一个人能够感知到可供性并由感知信息改变的阈值；而存在可供性与人之间相互作用的情境，对人与可供性的相互作用具有关键影响。文中提供了该模型的示例以及进一步研究的建议。
