DesignOfEverydayThings - Mapping

• Mapping is the relationship between the elements of two sets of things
• Ex. Switch mapping Lights in office 
• Mapping the layout of controls and displays
  
• Ex. Steeling a car, rotate the steering wheel clockwise to cause the car to turn right.
  
• Ex. Tank is different,its designed to control wheel speed because it uses track
  
• It doesn't matter whether these conceptual models are accurate: what matters is that they provide a clear way of remembering and understanding the mappings.
• Natural mapping leads to immediate understanding.
• Ex. to move an object up, move the control up.
  
• Ex. Make light control mapping same as lights in room
• Ex. Automobile Seat Adjustment control
  
• Note the "natural" is specific to a particular culture.
