Evaluating Usability of SAGRES Virtual Museum: Considering Ergonomics Aspects and Virtual Guides

摘要

The SAGRES Virtual Museum is an educational environment built on the Web that facilitates the organisation of visits to museums, presenting museums' information bases in a way adapted to the user's characteristics. SAGRES incorporates personal assistants to help the user during the navigation and operation of the system. As an educational environment it is important to evaluate the usability of SAGRES, because products with low usability are generally responsible for frustration, anxiety and low productivity, and they can allow the learner to arrive at mistaken or erroneous conclusions. So we developed some validations. We adopted two methods: tests with users and usability inspection. With these validations we identify some positive and negative characteristics of the system, considering the usability and ergonomics aspects of the interface.
