Approach to evaluate a user interface based on "the function it communicates", a personal interpretation derived from reflection of the meaning of GUI components and interaction for the user and the user experience.

Abstract:
This paper introduces an approach for evaluating user interfaces built on visual rhetoric and the rhetorical notion of function. A personal informatics mobile application has been selected to exemplify the application of this approach. Through the results of this example evaluation, this paper discusses the consequence of applying a rhetorical evaluation to a user interface. In this discussion, it is observed that inspecting the function performed by interface components takes into account experiences, communication, and meaning. In addition, it fosters reflection and criticism.

  16. 16. Takeaways & Conclusion
  17. 17. Takeaways • A rhetorical evaluation involves an anti-intentionalist position
  18. 18. Takeaways • A rhetorical evaluation involves an anti-intentionalist position • However, interactive systems challenge this idea
  19. 19. Takeaways • A rhetorical evaluation involves an anti-intentionalist position • However, interactive systems challenge this idea • Interaction with the system is crucial
  20. 20. Takeaways • A rhetorical evaluation involves an anti-intentionalist position • However, interactive systems challenge this idea • Interaction with the system is crucial • This form of rhetorical evaluation is placed between structural approaches and hermeneutic approaches
  21. 21. Takeaways • A rhetorical evaluation involves an anti-intentionalist position • However, interactive systems challenge this idea • Interaction with the system is crucial • This form of rhetorical evaluation is placed between structural approaches and hermeneutic approaches • This form of rhetorical evaluation fosters re!lection and criticism
  22. 22. Conclusion The goal is obtaining a wider perspective regarding the design of interactive systems, one that takes into account experiences, communication, and meaning
