InteractionDesign
What is the problem?
What are the consequences ofthe interactive systems that we design?
How do interactive systems affect the people’s everyday?
How are we, designers and researchers, contributing on making people to affect
other people?
What does it meanfor the members in
the team?
Swipe to the right for Like
Swipe tothe le!t for Nope
What does it meanbeing put on the
“nope” list?
A problematic of HCI and Design
Us, designers and researchers, contribute on deploying artifacts that affect the everyday of
people, including their beliefs and attitude

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

Discussion
Discussion
Evaluating an interface requires for the evaluator to learn about the system and
its purpose
Discussion
The evaluation considers the interaction with the system
Discussion
This form of rhetorical evaluation is placed between
structural approaches and hermeneutic approaches
Discussion
This form of rhetorical evaluation fosters reflection
and interaction criticism
Conclusion
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
Conclusion
The goal is obtaining a wider perspective regarding the
design of interactive systems, one that takes into account experiences, communication,
and meaning.
