To accelerate and simplify human activity recognition research, we have been developing a data processing tool named "HASC Tool." As the activity corpus becomes huge, it is not simple to handle the large number of files because it takes a lot of time to process. In this paper, we propose a distributed data processing mechanism which is implemented in the HASC Tool. By using the system, we can simply scale the local system into distributed processing. We also show the preliminary experimental result.

Human activity recognition through the wearable sensor will enable a next-generation human-oriented ubiquitous computing. However, most of research on human activity recognition so far is based on small number of subjects, and non-public data. To overcome the situation, we have gathered 4897 accelerometer data with 116 subjects and compose them as HASC2011corpus. In the field of pattern recognition, it is very important to evaluate and to improve the recognition methods by using the same dataset as a common ground. We make the HASC2011corpus into public for the research community to use it as a common ground of the Human Activity Recognition. We also show several facts and results of obtained from the corpus.

We introduce a subway information system which utilize WiFi location technology for supporting a person in the underground. The system is composed of a mobile terminal with a WiFi device and a communication server. We have developed seven location aware applications for the mobile terminal. Each of the application helps the user with current location information. We have performed a demonstration experiment in the subway of Nagoya City with 35 subjects and got a positive acceptance of the system.

Here, we propose a system named Azim that provides service based on both location and direction, which uses position estimation method based on azimuth data. In this system, a user's position is estimated by having the user point to and measure azimuths of several markers or objects whose positions are already known. Because the measurements are naturally associated with some degree of error, the user's position is calculated as a probability distribution. Since both the user's position and azimuth data are obtained in this method, both sources of data are used to realize more advanced services such as identifying the object pointed to by a user. The proposed system utilizes a wireless LAN for supporting these advanced services. Finally, a prototype system was implemented using a direction sensor that combines a magnetic compass and accelerometer, and we exemplify the usefulness of our approach through an experiment.

The spread of short distance wireless communication technology is making it possible for various information appliances to communicate through a network. However, to connect and to use them, we must generally perform complicated setup operations such as setting addresses or names. In this paper, we propose a user-friendly connecting management framework called " Touch-and-Connect". With this method, we can connect any networked devices only by touching them. This system is designed so that it can work without a server and even if many individuals operate it independently, no incorrect connections occur. And we have exemplified the usefulness of this framework with subject experiments.
