In two experiments, we investigated the stabilizing influence of vision on human upright posture in real and virtual environments. Visual stabilization was assessed by comparing eyes-open with eyes-closed conditions while subjects attempted to maintain balance in the presence of a stable visual scene. Visual stabilization in the virtual display w as reduced, as compared wit hreal-world viewing....

A bacterial display methodology was developed for N- and C-terminal display and demonstrated to enable rapid screening of very large peptide libraries with high precision and efficiency. To overcome limitations of insertional fusion display libraries, a new scaffold was developed through circular permutation of the Escherichia coli outer membrane protein OmpX that presents both N and C termini ...

The selection of a computer visual display system suitable for word recognition and reading research is described. The software character generation routines permit flexible definition of character sets. The display software permits control of size scaling and point density of characters being displayed as well as control over the temporal microstructure of presenting and refreshing the display...

A total of 85 VDU operators, in three main Scandinavian Alcatel-Lucent headquarters, were followed in a process moving from single occupancy offices to an office landscape. This paper discusses the visual challenges and implications in such a transfer. In the oral presentation recommendation on how to avoid visual problems will be given.

the effect of temperature on the main feeding parameters of mnemiopsis leidyi from the southern caspian sea was studied in 2002. the clearance rates and daily rations were estimated from laboratory experiments in a wide range of temperatures from 12 to 27 ?c for m. leidyi of 12?17 mm in length. clearance rate values changed from 52.5 to 107.3 ml ind-1 h-1. the coefficient q10 in temperature 12 ...

High Dynamic Range (HDR) images have been widely applied in daily applications. However, HDR image is special format, which need to pre-process known as tone mapping operators for display. Since the visual quality of HDR images are very sensitive to luminance value variations, conventional watermarking methods for low dynamic range (LDR) images are not suitable and may even cause catastrophic v...

Our objective is to realize wearable interfaces for expanding our information activities in daily life. To implement these interfaces, we employ vision-based systems, including a variety of camera, a head-mounted display and other visual devices. In this paper, we present two wearable vision interfaces; 1) object registration and retrieval and 2) virtual tablet input by fingertip drawing. In bo...

Our objective is to realize wearable interfaces for expanding our information activities in daily life. To implement these interfaces, we employ vision-based systems, including a variety of camera, a head-mounted display and other visual devices. In this paper, we present two wearable vision interfaces; 1) 2D gaze-region extraction from an observed image and 2) 3D gaze-position estimation. In b...

Background noise is often discussed in terms of mental costs. In this study the effect of background noise on brain activity as reflected by the direct coupled (DC) potential was investigated by a within design in ten participants. During two successive blocks of 7 min each, participants performed 156 trials of a visual display terminal (VDT)-based visual-spatial attention task without noise an...

(-)-Bornyl acetate is the main volatile constituent in numerous conifer oils and has a camphoraceous, pine-needle-like odor. It is frequently used as the conifer needle composition in soap, bath products, room sprays, and pharmaceutical products. However, the psychophysiological effects of (-)-bornyl acetate remained unclear. We investigated the effects of breathing air mixed with (-)-bornyl ac...
