Question

Difference between implementation model and mental model ques10

Answer 1

Answer:

Explanation:

Mental Models

1) Mental models are representations of systems and environments derived from experience.

2) People understand and interact with systems and environments by comparing the outcomes of their mental models with the real-world systems and environments.

3) When the outcomes correspond a mental model is accurate and complete. When the outcomes do not correspond the mental model is inaccurate or incomplete.

4) With regards to design there are two basics of mental models: mental models of how systems work (system models) and mental models of how people interact with systems (interaction models).

5) Designers generally have very complete and accurate models but often have weak interaction models-i.e. they know much about how a system works but little about how people will interact with the system.

6) Conversely users of a design tend to have sparse and inaccurate system models, but through use and experience commonly attain interaction models that are more complete and accurate than those of designers.

7) Optimal design results only when designers have an accurate and complete system model attain an accurate and complete interaction model and then design a system interface that reflects an efficient merging of both models.

8) Designers can obtain accurate and complete interaction models through personal use of the system, laboratory testing and direct observation of people interacting with the system or similar systems.

9) Use of the system by the designer will reveal obvious design problems but will fail to reveal the problems of interaction that emerge when people are unfamiliar with the system.

10) Laboratory testing is useful for evaluating designs in a controlled environment but most conducted with care as the artificial context and expectation effects can compromise the validity of the results.

11) Direct observation in the target environment is the preferred method for acquiring accurate information about how people interact with systems but is costly and impractical for designs that are not yet publicly available.

12) Design with people’s interaction model in mind. If there is a standard mental model for how something works, try to design leveraging that model.

13) When this is not possible create an interaction experience that draws from common mental models as much as possible such as the desktop metaphor for computers.

14) However, do not contrive design just to leverage a familiar model it is better to have people learn a new model that is clear and consistent than to use a familiar model that does not fit.

Answer 2

Difference between implementation model and mental model is given below.

Explanation:

Implementation Model:

• The implementation model  is the description of how the computer is operates. The Implementation model includes the  design, definition ,etc.

• The user interface is not dependent on the implementation model also the implementation is based on technology.

 Mental model

• The user interface is  dependent on the implementation model.
• Mental model is the interpretation of the user .The execution of mental model is same as implementation also in the mental model it is convenient for anyone to picture all the behavior as they actually did.
