Object oriented memory recollection and retrieval based on spatial log in the iSpace

In this paper, we propose a memory recollection and retrieval system using spatial log data in daily living which allows users to see behavior of the past, unconscious behavior and object-oriented behavior in the Intelligent Space. The proposed system consists of multiple camera devices and microphone and it utilizes various kinds of data; human identification, human motion, object instance, weather information, lighting intensity, heuristic information, etc. We constructed the system, focused on objects, in the Intelligent Space. To generate Metadata, based on collected log data to achieve the system of Recollection and Retrieval, several algorithms were used. This paper presents the prototype of Recollection and Retrieval System, and original dataset, useful for various purposes in the Intelligent Space.
