Usabilidade de software: um estudo do Catalogo Auslib

Abstract

The automation of information retrieval systems in libraries try to reduce the cognitive load of work, to perform specific tasks, which previously was done manually with chips in a catalog. With the automation of libraries and the help of the Internet, catalogs are now available online. So, it was carried out a study about the online catalog Auslib, wich aim was analyze automation softwares for libraries. This study was based on a hybrid approach scoped to verify the subjective satisfaction of the Sistemoteca’s users from the Federal University of Campina Grande. The public search module was analized, because it was already deployed and working. Were realized tests of interaction with students and staff. The usability happened as field survey and in the laboratory, attended by 128 users, according to all three prospects for evaluating the hybrid approach: a compliance inspection of the product, performance measurement and survey of user satisfaction. In the compliance inspection was decided to use parts: 14 - dialogues with menu, 16 - dialogues by direct manipulation and 17 - forms of dialogues. The choice of those parts of ISO 9241 was due to the modes of interaction, human-computer interface feature that - if the evaluated product. Part 11, ISO 9241:1998 was used to select assessment strategies in order to measure the performance and survey of user satisfaction. The instruments used for collecting data in this study were: questionnaires for delineation of the profile and subjective satisfaction of users, interview, test script, record video and list of compliance inspection. As a collection method was used verbalizing procedures for users to comment his acts. After the quantitative and qualitative analysis of the data, testing with users allowed to verify how they interacted with the interface Auslib Catalog. A result for the two categories of users as obtained as an index of a minimal satisfaction with the product, in both test environments, it’s justified by the list of faults detected in the module's public search software.It’s believed that the research has significantly contributed through usability guidelines proposed as a way to improve the product interface.
