Previous studies have found out that educational
applications using the Augmented Reality (AR) technology have
provided immersion, motivation, fun and high level of
engagement. However, designing and developing of the AR
courseware with these characteristics while ensuring the
effectiveness in teaching and learning process can be quite
challenging. The increasingly use of AR has called for the
creation of more usable products of high quality, which in turn,
makes the Usability Evaluation testing an essential process.
Previous researchers stressed that until very recently, where the
Usability Evaluation of AR interfaces had not been
systematically examined. Furthermore, nowadays usability is a
fundamental factor to consider when developing educational
courseware. Therefore, a good design for the usability evaluation
methodology is needed which is best suited for Down Syndrome
(DS) learners in early reading. This paper describes the review of
usability evaluation in learning courseware and presenting the
usability evaluation that has been successfully applied to
previous AR applications. Next, we will present several existing
usability evaluation methods as a guideline in conducting the
usability evaluation for AR BACA SindD. Lastly, this paper
proposed a Design of Usability Evaluation Methodology
Framework for AR BACA SindD, especially for the DS children
in this case study. Hopefully, the methods that were used for the
evaluation as well as the suitable usability evaluation
methodology proposed, can be deployed to evaluate the
effectiveness of the courseware to disabled children as general
and primarily to the DS children.
