Introduction

• The processing can be done in three steps, design is nothing but the effort to develop best user interface to communicate with machines.
• End user can share experiences by designing models and convert them into prototype for development.
• Three levels at which we process information available, the seven stages of our actions can be understood in simple way.
• Every stage will perform action on a particular level.
• Norman has given overview of such mapping.

 Level 1 :- Visceral level

• This is initial level of processing available information.
• In this step of processing human reacts to audio visual actions and other aspects of a product.
• The external look and touch feel of the product will dominate the user at this visceral level.
• A human need to decide things are good, bad, safe or dangerous.
• Human brains is trained to like or dislike things based on their own thinking level.
• E.g.
  
  • Boys like blue
  • Girls like pink
  • Kids like Red or dark colors
  • Indians like spicy food, etc.
• Visceral design often refers to creating best user interface and graphical appearance.
• The developer can have creative skills of a visual and graphical designs, it creates lot of impact to users.
• Once this level is approved, we proceed towards actual work.
• If this level is not designed properly, other levels will need more effort for product acceptance.
• The user of a product is one of the most critical to decide about product.

Level 2 : - Behavioral Level

• The emotional brain is important while making decision.
• The more detailed level of product description than visceral.
• It is very difficult to work with complex systems, than working on simple environments.
• Semantics and usability practices are addressed in this level.
• It decides the behavior and feedback given by the product.
• For example , a dialog box with an error message inform user about next step of action.
• ON and OFF mark on an electrical switch can simply explain its operation.

Level : - Reflective Level

• The final level of processing is analysis and reflection of all experiences is done in reflective level.
• All experience and its meaning is stored in human brain.
• This level mainly deal with analyzing past user experiences and future requirements to plan for goal.
• Then based user preferences, we choose a methods to execute plan.

Three Level overview

• Human emotions can affect decisions. These levels can be affected by human being.
• At the visceral level we perform the method.
• Physical aspects of performing the task can be considered.
• Human senses of vision, hearing, smell, touch and taste are used to perceive human actions.
