Norman Model Of Interaction Analysis

2.1.1. Norman’s Model of Interaction

The Donald Norman Model of Interaction is the most influential model in the Human-Computer Interaction. This was first introduced in 1988. This model will provide a framework for examining the interaction.

This model will function with the user choosing the goal, formulate the plan of action and then execute at the computer interface. When the plan have been executed the user will observe the computer interface to evaluate the results of the execution plan and then determine the further actions that will be taken. The model will be influenced by the ergonomics of the interface and will have two major phases.

The Execution phase will focus on the differences that exist between the user’s formulation of

This is the action state that the system would be in and would determine the actions that are actually available and the type if information that the system would actually need in order to operate.

The last stage is the Evaluation of the System State with respect to the goal. This means that the actual state that the system is in would be used to evaluate the actions available to the users and how the people would be allowed to interact with the system through the interface. This would then be used as a basis to determine whether the goals that was established in the first stage was met.

2.1.2. Abowd and Beale’s Interaction

The Abowd and Beale Model of interaction is built upon the Norman Model but it is designed to be more realistic. This model focus on the input, output, system and user. According to this model, the user is not solely responsible for the interaction in the Human-Computer Interaction framework. According to this model, the system will also have a role to play. Figure 1.2 General Interaction Model

On this model, the interface will sit between the User (U) and the System (S). There will be four steps that make up the interactive cycle of this model. This will be indicated by the arrowed lines. The User will formulate a task in order to ensure that a specific goal will be

This is a strikingly radical approach. Instead Nemirovsky is concerned with users as an audience that explore the media space. He goes on to discuss the environment which he defines as a framework for creation, modification, exchange and performance of audio visual media.

This would be composed of three layers

• Input that will be the interfaces that could be used for sampling

• Structural which is a neural network for providing structural control to the system

• Perceptual for the direct media modification

The Nemivorsky Model sees the members of the new audience as non-idiomatic improvers. Their performance are conceived as never-ending. Yet no continuous participation is expected. The users will always be free to step aside and be unconstrained by the obligations of a traditional performer.

Unlike with the roles in the traditional audiences, the new roles will be a subversion and creation of the new meanings rather than the mere consumption of the role. With the new model there is a greater disparity on the de-facto treatment on the computer audience and their needs. This model will outline the proposal for the participation of the
