Q3.1 | I S

defines an area of expertise and knowledge in some real-world activity. Some examples of domains are graphic design, authoring, and process control in a factory.

• domain

• tasks

• goal

• intention

these are operations to manipulate the concepts of a domain.

• domain

• tasks

• goal

• intention

It is the desired output from a performed task. For example, one task within the graphic design domain is the construction of a specific geometric shape with particular attributes on the drawing surface.

• domain

• tasks

• goal

• intention

It is a specific action required to meet the goal.

The 4th stage in Norman’s model of interaction

• 1. Executing the action.

• 1. Perceiving the system state.

• 1. Interpreting the system state.

• 1. Evaluating the system state with respect to the goals and intentions.

The 1st stage in Norman’s model of interaction

• 1. Establishing the goal.

• 1. Forming the intention.

• 1. Specifying the action sequence.

• 1. Executing the action.

The 7th stage in Norman’s model of interaction

• 1. Executing the action.

• 1. Forming the intention.

• 1. Interpreting the system state.

• 1. Evaluating the system state with respect to the goals and intentions.

the difference between the user’s formulation of the actions to reach the goal and the actions allowed by the system

• gulf of execution

• gulf of evaluation

the distance between the physical presentation of the system state and the expectation of the user

• gulf of execution

• gulf of evaluation

a framework attempts a more realistic description of interaction by including the system explicitly, and breaks it into four main components

• interaction framework

• hci framework

• ionic framework

• gulf of execution framework
