Ubiquitous computing

With the progress of the sensor technology, real-world phenomena have become easier to capture by using sensors, as various sensors have been mounted on game console or high -performance mobile terminal (smartphones).
However, since most of the sensor data are numerical series, in order to use such data by some application, these data must be analyzed and then abstracted to concepts that can be interpreted by humans. I have studied the sensor data processing and analysis meant to estimate the behavior or location of humans in a building by using sensor data obtained from smartphones, wearable sensors or ubiquitous sensors. Acknowledging someone's indoor location and behavior can help the realization of a variety of real-world applications, such as watching single-elderly, indoor navigation or permanent record of life information.
