Comparação de avaliações de usabilidade e acessibilidade nos portais novo e antigo da UNIPAMPA

Abstract

Accessibility and usability Web standards are now widespread among website developers. However, the understanding that each one of these concepts carries are diverse and often their development is not adequate. The goal of this work is to compare the usability and accessibility evaluation in two versions of the Federal University of Pampa (UNIPAMPA) website (new and old), which is a public higher education institution. Therefore, accessibility and usability should be observed in its websites and web systems. For this, it was applied usability testing with users, System Usability Scale (SUS) and automatic accessibility checker. Applying these techniques and analysing results, old website was the one that obtained the highest score on SUS and the fastest task fulfilment on user testing, while new website had the highest accessibility index on automatic checker. After these results, a statistical study (using T Test and U Test) was done to demonstrate the significant difference between average time to fulfil a task, average SUS scores and average accessibility indexes, showing that our interpretation of results is correct under a confidence level of 90 %. Subsequently, these results will be forwarded to the Information and Communication Technology Department (DTIC) of UNIPAMPA to evaluate potential improvements.
