Abstract
Stroke is the main cause of permanent disability in adults and one of the primary causes of death and disability worldwide. It is preventable and early detection of its symptoms lead to more effective treatment. This study investigated the use of handheld Augmented Reality (AR) application to instruct and increase awareness stroke and its symptoms among university students. The researcher developed an application called AugStroke that comprised a section that presented facts regarding stroke and followed by an exercise section to detect warning signs and symptoms of stroke. The exercise section employed the projection of augmented objects onto real-time videos of a subject as generated by the handheld devices. While on camera, the subjects were given specific tasks to perform and the learners would evaluate the performance by tapping on the corresponding answers provided on-screen. A diagnosis is generated after the subjects and the learners have completed all the tasks. The variables of this study were AR antecedents, namely, Interactivity, Focused Attention, and Perceived Control; Experience with AR, namely, enjoyment and telepresence; Consequences of using AR, namely, exploratory behavior and positive behavior; and Awareness of warning signs and symptoms of stroke. The survey method and stratified sampling were employed for this study. A total of 170 university students were asked to use AugStroke for six days and the participants were asked to
repeat the exercises with as many subjects as possible, focusing on older adults and the elderly. A total of 149 questionnaires were completed at the end of the study. Data was analysed using structural equation modeling in SmartPLS. The results showed that AugStroke provided the learners with the necessary antecedents that brought about meaningful experiences which then resulted in positive learning consequences that increased their awareness towards stroke. All the hypothesized relationships were significant and positive with small to medium path coefficients and effect sizes except for Perceived Control which reported no significant effect on Enjoyment. These findings indicated that in the AR environment the antecedent factors drove the experience factors that in turn drove the consequent factors and awareness towards stroke.
