Document Summary
How qualities of the environment or of objects influence how you interact with them (requires or demands you to respond) Types of interactions that are affected by affordance: human factors/ergonomics. Design: expectation: light switch example, norman door, touch interface: iphone 6 (apps are shaped as buttons) Heavily impacted by the concept of affordances: stimulus response compatibility. Ambiguity: stimuli may slow down processing and/or increase errors. Unambiguity: the bigger the una(cid:373)biguity, the faster you"re goi(cid:374)g to be. Spatial compatibility: how to map a response to a stimulus, effect in terms of reaction: if reacting to left stimuli with opposite hand without crossing them, its slower. Compatibility is not about the limbs itself but with the special placement of the stimulus and the limb. Tools: end state comfort effect: tend to interact with object as you want to have them in their end state, lifting up a mug that is flipped over.
