Ferramenta para a integração e análise de dados da avaliação de interfaces.

Abstract

This dissertation presents the development of a user interface evaluation-supporting tool. The work is based upon the assumption that the analysis and diagnosis of the problems found during a product evaluation must be supported by a database to integrate the related information collected though various evaluation techniques. The tool, developed in Java, was modeled in UML, in the software development environment Rational Rose2000. Its architecture consists of two modules: a database module and an analysis support module through which the user interacts with the database. The database, based upon the DBMS Oracle Server Si Relational-Object , stores data from a wide variety of evaluation techniques applied to the same version of a product, applied to different versions of the same product and data related to the evaluation of different products. The stored data can be of a variety of types such as text relative to the user opinion about the product, the usability specialist's evaluation or the evaluation session log recorded in video, audio or computer files. The analysis module supports the product evaluator during the writing of product usability reports, as it enables the access to all the information related to this and other product evaluations. In order to illustrate this tool's potential and limitations this dissertation presents three case studies involving the storage and retrieval of evaluation data. The work concludes with a discussion on the tools limitations and points to this work's future directions.
