“…A fatigue measurement experiment was carried out using a railroad driving simulator at Railroad Technical Research Institute (Tokyo, Japan) from Aug. 1 to Sep. 29 2005 (Shiomi, K. et al 2008). Eleven male university students and postgraduates at Tokyo Gakugei University, and one assistant professor, participated in the experiment.…”

The chaotic fluctuation of human voice is possible to calculate by SiCECA (Shiomi's Cerebral Exponent Calculation Algorithm) which adopt time-local definition of chaotic characteristics of time series. As results of experiments, follows were observed in chaotic fluctuation of human voice. The chaotic fluctuation of human voice, named CE (Cerebral exponent) showed correlation with speaker's psychosomatic condition. The value dependency on individuals was very small. If influences of recording equipments and environment are properly estimated, CE will be useful to evaluate speaker's arousal level.

“…Meanwhile, the effectiveness of non-superficial information is implied by several research. K. Shiomi et al point out that the human fatigue can be estimated by analyzing the voice of persons, and the workspace safety shall be improved by applying this information [1]. K. Kiyokawa et al try to improve the user's working efficiency by building a system that monitors the user's drowsiness and concentration [2].…”

Ambient intelligence aims to actualize the environment that sense and utilize information around us without making us perceive the underlying systems. This work extends this concept by allowing us to track the movement and orientation of people and objects instantly. The proposed system can sense and let us know, for example, who met or talked to each other frequently, to whom s/he is often facing in the meeting, what stuffs people often use, where the person left his/her belongings, etc. Such information will help the system to understand the behavior patterns of each person and consequently can support and improve the personal life of users and even their mutual relationship. This paper proposes an instant indoor magnetic tracking system that enables us to track the movement and orientation of people and objects by only attaching tiny electronic trackers to them. The size of the prototyped tracker is only 25.4mm × 25.4mm × 10.0mm, and hence it can be readily attached to almost anything and immediately activated. Evaluation results show that the proposed system applies to both room-scale tracking and tabletop scale tracking with 6 DoF (Degrees of Freedom).
