Recently, there are many studies on brain computer interface (BCI) system and some use EEG response at oddball paradigms. The aim of this paper is to extract feature (i.e. P300 response) from the EEG signals to improve the spelling system. We propose the method to analyze the averaged EEG signal concerned time and spatial. It is confirmed that the processing period with feature extraction is able...
The number of elderly people increases in Japan, and the development of welfare apparatus having the effect of minimizing care is required. In this research, authors develop intelligent power wheelchair along with minimizing care needs for frail elderly people. This intelligent power wheelchair features the four functions; approach function by human gesture recognition, standing up assistance, walking...
In this research, we develop an automatic driving system using for a compact electric car ldquoi-mobilityrdquo. The system supports an elderly person and a handicapped person to move somewhere. ldquoi-mobilityrdquo avoids obstacles by using environment information and laser-range-finder for safety. ldquoi-mobilityrdquo provides a service considering situation by using environment information which...
In this research, we propose two systems for a compact electric car ldquoi-mobilityrdquo, natural interaction system and automatic driving system with walking people in urban life. We think it is important to natural interaction between human to system. For that, we constructed nonverbal interface by using human natural motion. In this system, we focused on using pointing behavior for a natural motion...
A Portable Acoustic Caption Decoder enables a person who is deaf or hard-of-hearing to have access to audio announcements in public places if the auditory presentation accompanies embedded transcripts. Despite of discouraging results of studies indicating the low robustness of a signal that is transmitted through the air, our decoder successfully detected signals emitted from a loudspeaker located...
