How are we, designers and researchers, contributing on making people to affect
other people?

Us, designers and researchers, contribute on deploying artifacts that affect the everyday of
people, including their beliefs and attitude

Rhetoric as lenses for HCI
• Persuasion
• Content & Form
• Contingencies & People
• Metaphor, Metonymy, and other rhetorical figures
• And so on...

Discussion
![Page 55: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/55.jpg)
Discussion
Evaluating an interface requires for the evaluator to learn about the system and
its purpose
![Page 56: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/56.jpg)
Discussion
The evaluation considers the interaction with the system
![Page 57: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/57.jpg)
Discussion
This form of rhetorical evaluation is placed between
structural approaches and hermeneutic approaches
![Page 58: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/58.jpg)
Discussion
This form of rhetorical evaluation fosters reflection
and interaction criticism
![Page 59: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/59.jpg)
Conclusion
![Page 60: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/60.jpg)
Conclusion
• Approach for evaluating user interfaces based on the notion of function from visual rhetoric
• Apparent function
• Function performed by UI components and interaction with the system
• Reflection and interaction criticism
![Page 61: Presentation at Seminar I: Rhetorical Evaluation of User Interfaces](https://reader034.fdocuments.us/reader034/viewer/2022051411/547e4a4eb4af9fc9158b565e/html5/thumbnails/61.jpg)
Conclusion
The goal is obtaining a wider perspective regarding the
design of interactive systems, one that takes into account experiences, communication,
and meaning.
