Human-computer interface evaluation: not user-friendliness but design for operation.

Area of Science:

• Human-Computer Interaction (HCI)
• Design and Development Studies

Background:

• Traditional human-computer interface evaluation often focuses on achieving 'user-friendliness' as a distinct phase.
• This perspective may not fully capture the complexities of system operation in real-world contexts.

Purpose of the Study:

• To reframe human-computer interface evaluation as an integral, participatory activity within the design and development process.
• To emphasize the importance of system operation in practice as the central concern for evaluation.

Main Methods:

• Conceptual analysis of evaluation methodologies in design and development.
• Argument for integrating evaluation activities closely with other design processes.
• Focus on the practical application and embodiment of evaluation theory within the user interface artifact.

Main Results:

• Evaluation is more effective when viewed as a continuous, participatory process rather than a standalone quality assurance step.
• The practical operation of a system is the key focus for meaningful evaluation.
• Evaluation theory is intrinsically linked to the design of the user interface itself.

Conclusions:

• Adopting an integrated view of human-computer interface evaluation impacts both technical design and human factors considerations.
• This approach supports a more holistic and effective design and development lifecycle.
• User interface evaluation should be a dynamic, embedded component of system creation.
