The smart diagnosis technology is a part of smart home technology, which utilizes smart home
appliances and wireless technology, and provides a diagnosis of abnormal situations. The awareness of the
abnormal situation during the use of home appliances is necessary in terms of usability and safety, but
many disabled people and elderly people have difficulties in this process. In this study, two major
companies in domestic appliance manufacturers identify the status of accessibility technology of smart diagnostic applications applied to home appliances, identify the problems, and suggest ways to solve them.
The appliances to which Smart Diagnostic App is applied are refrigerator, washing machine, air conditioner,
smart TV, electric rice cooker. The smart diagnostic apps used in these products were based on camera
module based, Wi-Fi based, and tag-on methods. Diagnosis and action for abnormal situations can be
divided into three stages. In the first stage diagnosis procedure, accessibility problem appears in the
application based on the camera module and the tag-on method. In the two-step notification procedure,
accessibility problems appeared in camera-based, Wi-Fi-based, and tag-on methods. In the three-step
procedure, accessibility problems were found in camera-based and Wi-Fi-based methods. As electronic
products and services evolve rapidly, the need for smart diagnostic apps that take into account the physical,
sensory, and cognitive functions of the disabled and the elderly is becoming increasingly important.
Therefore, it is urgently necessary to establish relevant research, laws and institutions.
