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.
