This paper is the consensus of a workshop that critically evaluated the utility and problems of video playbacks as stimuli in studies of visual behavior. We suggest that video playback is probably suitable for studying motion, shape, texture, size, and brightness. Studying color is problematic because video systems are specifically designed for humans. Any(More)
SUMMARY This paper proposes genetic algorithms (GAs) for path planning and trajectory planning of an autonomous mobile robot. Our GA-based approach has an advantage of adaptiv-ity such that the GAs work even if an environment is time-varying or unknown. Therefore, it is suitable for both off-line and on-line motion planning. We first presents a GA for path(More)
ntroduction The proposed publishing model described in the latter half of this article has been developing in my mind for over five years. The beginnings of this model can be traced back to an idea for network-based scholarly publishing which I described at a meeting held at the Royal Society in 1993 1. I also described variations of this early model to(More)
Prior studies have found that subjects prefer an improving sequence of income over a constant sequence, even if the constant sequence offers a larger present-discounted value. However, little is known about how these preferences vary with the size of the wage payments. In each of four studies, we find a positive relationship between the preference for(More)
Previous work demonstrates that memory for simple stimuli can be biased by information about the distribution of which the stimulus is a member. Specifically, people underestimate values greater than the distribution's average and overestimate values smaller than the average. This is referred to as the central tendency bias. This bias has been explained as(More)
OBJECTIVES State Children's Health Insurance Program (SCHIP) in the USA plays a critical role in healthcare service utilization. This study assesses children's needs for healthcare services among the variations of SCHIP. METHODS This study applies the PRECEDE-PROCEED behavioral model to analyze the behavior of children with healthcare needs and unmet(More)
We had trial broadcast for a university graduation ceremony with telepresence. One of the graduates carried a laptop computer with a camera with him, and we broadcast the video image from the camera on the Internet. The audience on the network experienced telepresence at the graduation ceremoney. We report our experiment system configuration and the(More)
