The goal of this living-lab clinical trial is to test the effectiveness of digital health monitoring and feedback platform for community dwelling older adults. The main questions it aims to answer are: * Identify digital sensing variables that are predictive of mental and physical health declines and health emergencies of older adults * Develop digital health monitoring service to inform individualized daily health status of older adults users * Develop ICT network to share the daily health status and emergency signals with community based healthcare service providers and family caregivers if an older adult user approves of them to receive their health information. Participants will be asked to participate in a living lab using a wearable sensor, motion sensor, and smartphone applications for 6 weeks and also take part in pre-mid-post surveys to evaluate the usability, accuracy, and effectiveness of the digital healthcare service platform to improve health managements and connections with community and family caregivers. If there is a comparison group: Researchers will compare age and gender matched control group to see if health status of the living-lab group is better than the control group.
