Development of Media on the Instruction of Inhaler Use in Asthma and Chronic Obstructive Pulmonary Disease Using Augmented Reality Technology

Abstract

Objective: To develop the media for providing knowledge for patients with asthma and chronic obstructive pulmonary disease using augmented reality technology, evaluate the efficiency and effectiveness of the media, and assess users’ satisfaction. Methods: The researcher developed augmented reality media using the ADDIE Model using the Unity3D and the Vuforia Engine. The media consisted of 8 domains of knowledge on MDI. Users could scan MDI packages with smartphone camera to access the media. The media was evaluated for its effectiveness by four experts in information technology. Investigators determined media effectiveness by assessing the correctness of MDI use and MDI knowledge of two randomly allocated groups of participants, i.e., the group receiving instruction on MDI use through the media (media group) and the group receiving advices from a pharmacist (pharmacist group). Assessment was made immediately after viewing the media or receiving advices. The satisfaction with media was assessed in the participants receiving instruction on MDI use through the media. Results: The media with augmented reality had an overall efficiency of 85%. Regarding the effectiveness, the average score of the media group on understanding of technique in MDI use was 11.33±1.44 out of 13, which was not different from that in the pharmacist group (11.60±0.67). Mean MDI of the media group was 8.87±1.07 out of 10, which was significantly higher than that of pharmacist group (8.30±1.06) (P<0.05). Media group had average score on satisfaction with media at a high level (4.50±0.12 out of the full score of 5), with the highest satisfaction score on inhaler use knowledge (4.67±0.61). Conclusion: The augmented reality media on the instruction of MDI use developed in the study could be used as an effective and efficient educational tool for patients with asthma and chronic obstructive pulmonary disease. Patients are satisfied with the use of media. The results of this study can be applied in the development of media for providing knowledge in other medications and health problems.
