This study intended to examine the willingness to use as well as necessary functions for ICT-based care assistance devices in older adults living alone. A total of 241 older adults living alone from a city participated in the study. Study results show that many older adults living alone are willing to use ICT-based care assistance devices at their home and the functions of care assistance devices that they perceived as necessary were diverse. In addition, there were differences in perception of functional necessity by socio-demographics and medical and functional characteristics of older adults living alone. In particular, there were significant differences in the functions perceived as necessary according to the presence of osteoporosis, depression, insomnia, and limitations in daily activities. Our study findings suggest that the functions of ICT-based care devices should be developed in various ways in order to help healthy aging in place. Findings also imply that it is necessary to provide individualized services and customized care assistance devices according to individual's medical and functional characteristics and needs.

The purpose of this study was to translate QUEST 2.0 in Korean with valid translation process and to measure psychometric characteristics. Translation process was consist of six steps. Internal consistency was analyzed by Cronbach's ${\alpha}$. Test-Retest reliability was analyzed by Spearman Rank Correlation Coefficient. Internal consistency of 'Assistive device' was .88, 'Services' .92. There was no statistically significant difference according to repetitive measure. The spearman correlation coefficient was .64 for "Assistive Device" and .66 for "Services". This result reflects K-QUEST 2.0's (Korean-Quebec User Evaluation of Satisfaction Assistive Technology 2.0) safety, consistency, and predictability in aspect of measure. In this study, the K-QUEST 2.0 was translated into Korean and the reliability of K-QUEST 2.0 was tested. Decisively, the K-QUEST 2.0 can be applied to evaluate user satisfaction of assistive technology.

In this paper, we propose a barrier-free course route navigation service named "Theme Road" aimed at improving the mobility and convenience for elderly electric wheelchair users with walking disabilities. To achieve this goal, we conducted a user survey through shadowing and in-depth interviews to gather insights on the challenges experienced by elderly electric wheelchair users. We identified potential solutions for each inconvenience through co-creation workshops, resulting in a set of design considerations and app functionalities. Using persona development and service scenarios, we designed and implemented the "Theme Road" service as a dedicated navigation application for barrier-free course navigation. Unlike conventional route navigation and mapping services, our study stands out by offering a unique approach that combines recommended destinations and safe routes based on experiential analysis from elderly electric wheelchair users.

This study is aimed to introduce the newly developed mobile application for effective provision of assistive devices for people with disabilities in South Korea. By combining of ICF code and ISO 9999 code, more effective way of searching user fit assistive device information and selecting appropriate assistive devices were possible. 10 people with visual impairment were recruited for an usability testing. For the data analysis, paired t-test were used and confidence interval was 95%. The result showed newly developed mobile application was more effective in comparison with on-line based assistive device information. The outcome of this study will enhance the provision of assistive devices for people with disabilities more effectively within better user understanding of their needs and compensate for their body function as well as environmental barriers.

In the era of digital transformation, the transportation underprivileged remains as an underprivileged class without the benefits of technological advances. Electric assist devices for the People with disability are inadequate to provide services suitable for the current traffic environment, although the mobility of the People with disability is improved. In this paper, we develop IoT smart mobility by deriving essential elements through user satisfaction surveys to efficiently move physical distances based on the experience of users using existing electric assistive devices. Based on the data collected through user satisfaction survey, quantitative analysis using TF-IFD and qualitative analysis based on QFD are performed to determine the importance of user requirements. For the evaluation of IoT smart mobility design results reflecting essential functions, usability verification is conducted by forming an expert evaluation team in various fields. In the future, we plan to conduct a service design study that can improve mobility convenience and provide mobility service solutions by designing to provide efficient public services by utilizing IoT smart mobility to the People with disability.

Recently, N-screen service and secondary device have gotten an attention from public. Also, we can experience N-screen service through various digital devices. N-screen means multimedia technology which can seamlessly consume multimedia content. Secondary device means auxiliary multimedia device which can consume content related to main content through adjunct connection to main device. Not only be electronic manufactures interested in N-screen technology and services but also digital devices applied for N-screen have been released. But it has limitation that user can only consume content to be purchased from content company server not device of user. This paper proposes the system that composes effective and various N-screen multimedia service through MPEG-4 LASeR (Lightweight Application Scene Representation) PMSI (Presentation and Modification of Structured Information) as international standard technology which can provide scene description including many instruction for dynamic update of scene.
