Affordance
可供性。物体或环境暗示其使用方式的属性。由心理学家 James J. Gibson 提出，后被 Don Norman引入设计领域。
English Definition
"A property of an object or environment that suggests how it can be used. Coined by psychologist James J. Gibson and later adapted to design by Don Norman."
用法说明 · 针对中文母语者
中文常翻译为'可供性'或'示能性'。在 HCI论文和 UX讨论里几乎必出现，指一个按钮/控件'看上去就能点'的设计属性。
常见错误
- ·不要和 'feature'混淆 —— affordance强调的是'提示用户如何使用'，而不是功能本身。
- ·日常对话中更常说 'visual cue' 或 'signifier'（Norman 后来用 signifier替代了部分 affordance 的用法）。
