Software as Rhetorical Visual Argument

See presentation slides

This study analyzes the web app "Gaza Everywhere" and illustrates how software could function as a visual rhetorical argument (i.e., a visua enthymeme), and how this notion outlines a user-centered persuasive experience.

Rhetorical Evaluation of User Intefaces

See presentation slides

This project introduces a schema for assessing and reflecting on the meaning derived from the denotation and connotation of interface components changing over time. This is based on the concept of "rhetorical evaluation," a schemata for performing rhetorical criticism (Foss, 1994).

Exploration of Rhetorical Concepts in UX/UI Design

See presentation slides

This project reinteprets the modes of appeal (logos, ethos, and pathos), rhetorical operations, and rhetorical figures (tropes and schemes) from classical rhetoric for user interface design and user experience design. It is based on the "Rhetorical Handbook" by Hanno Ehses & Ellen Lupton (1988).

UX Design Methods and Practice

See more about this project.

In my role as reserach assistant, I try to understand the diverse factors, including knowledge sources, that contribute in the development of competence in User Experience Design. This research belongs to an nsf-funded research project on Design Methods and Practice, having Prof. Erik Stolterman as p.i.

Security & Privacy in User Experience Design

See presentation for DIS 2014

Large-scale Communication Systems, such as social media, can be perceived as complex systems due to the changes over time regarding their number of users, use scenarios, and their information and communication technological infrastructure. These factors cause security and privacy concerns that might affect the experience of use. This work is an attempt to open a conversation about these topics in the field of UX design.

Design-oriented Pedagogy for Human-Computer Interaction

See presentation for DRS // Cumulus 2012

We propose a pedagogical framework based on narratives for a studio-based hci course. Then, we talk about a conceptual space called the narrative cloud, in which stories are used as part of the course in order to engage students into reflection. We think that stories make students sensitive, and they also foster the development of design thinking.

Research Projects before PhD Program

Methods for User Interface Design

See presentation for CIDI 2009

We proceeded to explore methods and approaches to inform and lead a design process. Our exploration included the Experience Sampling Method, the Needfinding Framework, the modes of appeal in Rhetoric, and the Communicability Evaluation from Semiotic Engineering.

Stochastic Particles Model for Image Processing

Read thesis (Spanish)

The gray value at each pixel can be interpreted as a set of particles that can move stochastically to the 8-pixel neighborghood. Certain type of functions affects such movement, causing a creation-and-death stochastic particles system. Then, we used this approach for exploring nonlinear filtering and segmentation in digital images.
