USABILITY ASSESSMENT FOR DEVELOPMENT OF AUGMENTED REALITY FOR GEOGRAPHICAL INFORMATION SYSTEM
Abstract
The development of Augmented Reality (AR) for learning Geographical Information System (GIS) involves several challenges pertaining usability. Thus, this study conducted usability assessment during development of AR package for learning GIS (ArGIS) for undergraduate students in Gombe State, Nigeria. The study was based on design and development using pre-test and post-test. The population for the study comprised 194 undergraduate students from two universities in the state. The participants were purposively sampled using two intact classes of 84 in experimental group and 110 in control group. A sample of 15 experts from Instructional Design, GIS and Computer Science were involved in the study. A 3rd version Post-Study System Usability Questionnaire (PSSUQ) widely used in Human Computer Interaction (HCI) was adopted for the study. The PSSUQ was a standardized tool with 0.90, 0.91 and 0.83 reliability coefficients for system usefulness, information and interface quality respectively. The PSSUQ was administered both during and after development of the package. The findings revealed that the ArGIS was rated 94.875% and 97.35% usable by experts and students respectively. The study concluded that usability assessment of mobile package depends on the users, their characteristics and skills, the task they want to perform as well as the context of use. It was therefore recommended that usability assessment should be carried out throughout AR package development process for satisfying the desired learning needs in GIS and remote sensing tasks
