Abstract: Educational systems based on the augmented reality (AR) technology are creating a new kind of user learning experience by bringing real life objects into a computer environment. The mix of the real and virtual world requires the design of new interaction techniques which have to be tested with users early in the development process. For these new e-learning systems to be effective traditional usability evaluation is not enough. The adoption of AR-based e-learning systems in schools also requires an investigation into the perceived usefulness and increase in students’ motivation. This paper presents a measurement model for the usability evaluation of AR-based e-learning systems that is targeting the educational and motivational values. The model was developed during a European research project and is inspired from the technology acceptance theories. The scale development was carried on in a methodological approach starting with the definition of a conceptual model from which an initial scale of 28 items was generated. The evaluation of the measurement model which is based on a confirmatory factor analysis resulted in a reliable scale with 19 items organized into five constructs.

Keywords: Technology acceptance models, AR, e-learning, usability evaluation, user experience.
