Human-centered design

human factors: memory systems

• Information Processing Model

memory: sensory

memory: working

memory: long-term

sensory memory: processing

• Sensory memory facilitates feature analysis and pattern recognition which allows us to recognize friends and friendly user interface elements

• Recognition involves both bottom-up processing and top-down processing

• Perception is based upon bottom-up processing and helps us to distinguish between data elements.
• Top-down procession provides interpretations of data. These are colored by our understandings of specific contexts and environments
