Personalized life log media system in ubiquitous environment

In this paper, we propose new system for storing and retrieval of personal life log media on ubiquitous environment. We can gather personal life log media from intelligent gadgets which are connected with wireless network. Our intelligent gadgets consist of wearable gadgets and environment gadgets. Wearable gadgets include audiovisual device, CPS, 3D- accelerometer and physiological reaction sensors. Environment gadgets include the smart sensors attached to the daily supplies, such as cup, chair, door and so on. User can get multimedia stream with wearable intelligent gadget and also get the environmental information around him from environment gadgets as personal life log media. These life log media(LLM) can be logged on the LLM server in realtime. In LLM server, learning-based activity analysis engine will process logged data and create meta data for retrieval automatically. By using proposed system, user can log with personalized life log media and can retrieve the media at any time. To give more intuitive retrieval, we provide intuitive spatiotemporal graphical user interface in client part. Finally we can provide user-centered service with individual activity registration and classification for each user with our proposed system.
