The objective of this paper is to evaluate pilots' body and physiological performance during their works using a large model sensor (tri-axial accelerometer and atmospheric pressure sensor) and a heart rate monitor toward safe harbors. The dis/embarkation experiment is carried out for the real pilotage. The results show that the largest acceleration 1.5–2.0 G appears during transfer from a pilot ladder...
This work describes the implementation and the modeling of a gas sensor with delta-sigma architecture. Beyond the conventional technique of periodic heating of light source, our proposed delta-sigma architecture with closed-loop system is obtained by the hybrid combination of a CO2 (Carbon dioxide) infrared sensor prototype which includes an amplifier, FPGA and discrete electronic devices. After a...
The degree of fatigue after watching 3D contents on commercially available 3DTV that requires the use of shutter glasses was evaluated under various viewing conditions. 500 adults aged between 20 and 69 years and 131 minors aged between 12 and 19 years participated in this experiment. The results indicate that the adult participants showed significant differences in the subjective sensation of fatigue...
This paper illustrates the effectiveness of a proactive data transfer scheme for adaptive display control in a distributed haptic system with virtual reality, which is an application using haptic, audio and visual media. Presentation experiments of an audio-visual stimulus were carried out using a computer graphics of a moving ball and its collision sound. The results obtained show that the sound...
In this paper, we present a tablet system that measures and visualizes who speaks to whom, who looks to whom, and their cumulative time in face-to-face multi-party conversation. The system measures where each participant is and when he/she speaks by using the front and back cameras and microphone of tablets. The evaluation result suggests that the system can measure such information with good accuracy...
