Evaluation deficit
In computer science, the gulf of evaluation indicates how directly a system or artifact is represented, perceived and interpreted using representation theory (more precisely group theory) with regard to the expectations and intentions of the user can. The evaluation deficit indicates how difficult it is to describe a system and its condition. Donald Norman's The Design Of Everyday Things states, "This gap is small when the device provides easy-to-understand and interpretable information about what state it is in and whether that state matches how the person thinks about the system . "
In human-computer interaction, the evaluation deficit represents the psychological gap to be overcome between the user and the user interface according to the following steps: Interface → Perception → Interpretation → Evaluation.
