최근 스마트기기가 발전함에 따라 종이책이 아닌 다양한 전자책뷰어가 등장하고 있다. 애플의 아이패드(iPad), 아마존의 킨들(kindle)과 같은 태블릿, 전자책 또는 스마트폰이 대표적인 예이며 스마트기기의 사용자 증가로 전용 단말기가 아닌 스마트폰 중심의 전자책 시장도 크게 성장하고 있다. 하지만 시니어 또는 스마트기기 사용을 어려워하는 사용자들이 전자책을 사용하는데 어려움을 느끼기 때문에, 전자책은 종이책에 비해 여전히 낮은 이용률을 나타내고 있다. 본 논문에서는 얼굴 표정에 따라서 전자책 설정을 자동으로 변경해 주는 방법을 제안한다. 제안한 방법은 표정감지를 위하여 OpenCV 라이브러리를 이용하여 얼굴을 검출하고, Haar-Like 피처 기법으로 사용자의 눈 모양을 검출한다. 눈이 감겨있는 경우와 찌푸린 경우를 감지하여 이에 맞게 글자크기와 화면을 자동으로 설정해 준다.

This content is implemented for active seniors who actively accept IT digital content as the current metaverse generation arrives. The elderly living in the nursing home can directly explore various parts of the map through the user scenario, so that they can recall their youth or experience various views, such as a place where they spent their lives in the past or a place where they can experience their jobs. In the current situation where the aftermath of Corona is getting stronger, the elderly living in nursing homes can have a positive effect on psychological stability and prevention of depression by using this content.

This study examines the case of living lab led by intermediary and explores the development possibility as living lab platform. The analyzed cases are 'The Seoul Innovation Park Living lab', 'Korea Senior Living lab' of Seongnam Senior Experience complex, and 'Disaster Safety Living lab'. As a result of the analysis, all three cases have formed a user panel to form a living lab platform, and provide living lab service to internal and external organizations. A common feature that combines a technology platform with a 4Ps-based governance platform is identified. However, the characteristics, the meaning, and the process are different from case to case. In the future, the living lab platform needs to share learning experiences that are going on individually, since domestic living lab platform is in the early stage. Through this, it is necessary to seek collaboration and cooperation with related similar projects, and to jointly promote institutional and physical infrastructures related to living labs.

This study developed a voice recognition chatbot system to address depression and loneliness among the elderly in an aging society. The system utilizes the Whisper model, GPT 2.5, and XTTS2 to provide high-performance voice recognition, natural language processing, and text-to-speech conversion. Users can express their emotions and states and receive appropriate responses, with voice recognition functionality using familiar voices for comfort and reassurance. The UX/UI design considers the cognitive responses, visual impairments, and physical limitations of the smart senior generation, using high contrast colors and readable fonts for enhanced usability. This research is expected to improve the quality of life for the elderly through voice-based interfaces.

This paper is a study on the digitization of an analog 3D pen. The term digital implies features such as homeostasis, transformability, combinability, reproducibility, and convenience of storage. One device that produces a combination of these digital characteristics is a 3D printer, but its industrial use is limited due to low productivity and limitations with materials and physical characteristics. In particular, improvements are required to use 3D printers, such as better user accessibility owing to expertise and skills in modeling software and printers. Complementing this fact is the 3D pen, which is excellent in portability and ease of use, but has a limitation in that it cannot be digitized. Therefore, in order to secure a digitalization capability and ease of use, and to secure the safety of printing materials that pose controversial hazards during the printing process, research problems and alternatives have been derived by combining food, and digitization was demonstrated with a newly developed 3D pen. In order to digitize the 3D pen, a sensor in a structured device detects the motion of an analog 3D pen, and this motion is converted into 3D data (X-Y-Z coordinate values) through a spatial analysis algorithm. To prove this method, the similarity was confirmed by visualization using MeshLab version 1.3.4. It is expected that this food pen can be used in youth education and senior healthcare programs in the future.
