The remarkable development of information and communication technology is moving toward the pursuit of digital automation of everything throughout society. However, the elderly have various difficulties in using digital devices due to physical, cognitive, and psychological changes caused by aging. Digital kiosks, which are common to society as a whole, should be designed so that users can naturally induce behavior and achieve their purpose even if they do not understand how to use and operate the device to achieve their purpose. This study attempted to evaluate the convenience of using digital kiosks for the elderly using affordance, constraint, mapping, and feedback, which are four basic concepts of affordance design that value the user's behavioral perspective. To achieve the purpose of the study, we actually used digital kiosks in community centers, subways, and commercial spaces for elderly experimental participants. Participants used community centers and subway devices relatively easily, but digital kiosks in commercial spaces had difficulty in using them. When participants were cognitively able to guess or know how to use the device, it was found that not only self-efficacy but also confidence in using the device was formed. Through this experimental process, the psychological factors felt during the post-occupancy evaluation and use of elderly participants were summarized. Through this study, it is hoped that a plan to improve the design of digital kiosks considering the physical, cognitive, and psychological characteristics of the elderly will be sought.
