This study intends to present a comparison about evaluation of usability and accessibility, which required the creation of two multimedia prototypes named “Moodle” and “Job Search Techniques”, under the project (e-Pris) e-Learning in Prisons.
We have built our multimedia prototypes using a conventional model of instructional design, ADDIA. This model demanded the planning of the multimedia prototype, the elaboration of the materials and of the usability tests, with the experts and with the users whose characteristics are similar to those in the target group, as well as the preparation of the accessibility tests.
While assessing the usability of the multimedia prototypes, by replacement users with similar characteristics to the target public, we have verified that learning to use the prototype (Learnability), executing all tasks efficiently (Efficiency) and with satisfaction (Satisfaction) were easy. The prototypes have proved to be also somewhat prone to errors (Errors). Nevertheless, we have not properly assessed the memorizing skills’ parameter, related to the ease of remembering the prototype’s functionalities (Memorability).
The evaluation of the accessibility has allowed us to make further improvements to the use of the prototype, not just for the users with special needs, but to all the users.
