1 ,, Proposal of Application Framework Synchronized with Portable Sensing Devices Akinori Sakamoto, 1 Kazuki Sakamoto, 2 Takaaki Myoujou, 3 Masahiro Ichikawa, 3 Ismail Arai 4 and Nobuhiko Nishio 5 Recently, sensor-equipped portable devices have become popular. Mining collected sensor log enables various services which adapt to personal situation. As such context-aware services increase,many frameworks are studied to manage sensor logs effectively. Current approach faces the problem of difficulty in real-time context mining. In this paper, we propose an application framework which synchronizes server-side and mobile framework to address the problem and its prototype is developed. 1.
