VDI UX Benchmarking

User Research

I participated in a benchmarking to investigate the UX aspects of three VDI solutions (Virtual Desktop Infrastructure) using eye tracking equipment.

Ten VDI specialists participated in the study answering questionnaires and performing the same tasks in the three evaluated tools. We analyzed both qualitative and quantitative data using objective metrics, such as performance and satisfaction rates. In this analysis, we also considered the comments and the visual behavior of participants.

Accessibility in Smartphones

User Research

I participated in a study that served as input to conceive an accessibility framework for touchscreen smartphones. In the initial phase of this study, I conducted two workshops with groups of visually impaired people to understand how they use and make sense of current mobile technologies.

Smart Grid Field Study

User Research

I participated in the preparation and application of questionnaires, and in field observations to survey customers' profile and their concept of smart grids.

The research included a random sample of more than 70 residents of Fernando de Noronha Island, and the results guided technical decisions in the remainder of the project.

Iconic Authentication

User Research

I conducted interviews with users in order to understand the authentication process in smartphones, and identify necessary improvements in it.

I also participated in the evaluation of prototypes of iconic authentication, considering paramenters such as icons repertoires, password size, and number of icons on the screen. In addition to conventional metrics, we analyzed eye tracking data from user interaction.

VDI Solution

Interaction Design

Low-Fidelity Prototypes

Using input from a UX Benchmarking research, we developed the first mockups of the new LG® virtualization solution using Balsamiq.

High-Fidelity Prototypes

Our final delivery was an interactive prototype in HTML accompanied by a UX recommendation guide. These artifacts were meant to guide the development team in the implementation of the final product.

The prototype detailed the design and behavior of the main functionalities of the VDI Solution. The document accompanying the prototype explained the design principles, design rationale and guidelines for development of future functionalities.

Virtual Container App

Interaction Design

I coordinated the interaction design of an Android application suite for secure communication.

Low-Fidelity Prototypes

I designed the wireframes and the interaction map for 6 apps during several development cycles that involved other designers, developers and stakeholders. Each cycle had quick usability evaluations.

'Box Seguro' App

Interaction Design

I workerd on the interaction design of a security Android app that used biometric authentication (face and voice) and iconic passwords.

Low-Fidelity Prototypes

I worked on the wireframes and part of the graphical design of the main screens. We conducted quick usability tests with the wireframes, and evaluated usability and user accpectance of the final prototype.

Pixel Perfect Mockups and UI Style Guide

Graphic Design

In this project, the padronization and visual identity of the application suite was essential. We created this visual identity and style guide incrementally. The focus was on a coporative audience that has great concerns with secure communication in their devices.

We created the application logos, color palettes, typography, and we also conceived the graphical design of the main screens using Adobe® Illustrator.

Conceptual Prototype

Graphic Design

In this design challange promoted by GSMA, we proposed an Android Home Laucher and a widget for resource-poor women in the developing world.

The proposed solution was among the ten finalists of the competition, and its main differential was in the simple interactions and low information density in the screen.

The proposed S.O.S. widget facilitated making calls and voice messages in emergency situations.

Usability and Eye Tracking Evaluation

Interface Evaluation

We conducted usability tests complemented with eye tracking data of the CEMIG Virtual Agency. Ten participants were randomly invited to explore and perform four quick tasks at CEMIG Virtual Agency.

The results were analyzed qualitatively using: data from participants' performance in the tasks, and user feedback, such as comments, difficulty level, and satisfaction. We delivered a report with improvement recommendations for CEMIG.

Accessibility Evaluation

Interface Evaluation

As law enforces that banks must provide services accessible for all, I participated in a team to evaluate the accessibility of Mercantil do Brasil Internet Banking.

Beyond evaluating the adequacy of the code to web accessibility standards, such as WCAG and eMAG, we invited a blind user to explore and perform tasks using industry leading screen readers.

We used the think-aloud protocol, and the problems we found were used as input in the system redesign.
