What is Mental Model ?
Actually mental model in dictionary means, “model of psychic”.. :p Just kidding..
Well Mental model is a term widely used by all designers and basically user experience designers. This term hardly comes out of visual designer or designer.
So, mental model is a “representation that a person has in his mind about the object he is interacting with.” Basically, every person has a different mental model.
Its better to explain it looking at this example –
“when getting a book out of the library, they form a mental model of the things they have to do to achieve this.”
“the accelerator pedal in a car is perceived by the designers as a means to inject more fuel to the car engine. However, the driver perceives it as a means to go faster (ignoring the mechanical implications). Both visions are different but consistent.”
