Scenario and Task Based Interview to Evaluate Usability of Computer Assisted Data Collection

This article aims to present the method of usability evaluation called Scenario and Task Based Interviews (STBI). The method was proposed to add flexibility to field usability testing, so that they could be applied to the context of The Brazilian Institute of Geography and Statistics (IBGE). IBGE is the institute of Brazilian central Administration that performs the Census and other important official demographic and economic data collection. This evaluation technique was specifically designed to be implemented with the participation of interviewers who use PDA (personal digital assistants) to perform data collection for statistical research in Brazil. The authors analyzed the usability of the application developed for PDA to support the Continuous National Household Sample Survey (Continuous PNAD). The method proposed in this paper represented a mix of four approaches to usability evaluation.

Pervasive Information Architecture and Media Ecosystem: A Brazilian Video on Demand User Experience

This paper evaluates user’s consumption and interaction with video on demand focused on the Globo Play app provided by Brazil’s largest TV network: TV Globo. Globo Play stands as an answer to the video on demand request addressed by Globo in a market scenario filled with world competitors like Netflix and Youtube. Cooperative evaluation and SUS results pointed out that there still is much to do in order to improve and to meet user’s requirements in what concerns quality of interaction, according to pervasive information architecture guidelines. User sessions indicated non-attendance to some usability issues as well. We came to the conclusion that the new world of ubiquity and pervasiveness probably does not make the traditional aspects of usability and user’s experience disappear.

Evaluating Interaction Design in Brazilian Tablet Journalism: Gestural Interfaces and Affordance Communicability
