In this paper we describe a new way to improve the usability of complex hardware setups in Instrumented Environments (IEs). By introducing a virtual character, we facilitate intuitive interaction with our IE. The character is capable of freely moving along the walls of the room. In this way, it may offer situated assistance to users within the environment. We make use of a steerable projector a...

Since the professional technical literature include amounts of complex noun phrases, identifying those phrases has an important practical value for such tasks as machine translation. Through analysis of those phrases in Chinese-English bilingual sentence pairs from the aircraft technical publications, we present an annotation specification based on the existing specification to label those phra...

A room may be used for a wide variety of performances and presentations. Each use places different acoustical requirements on the room. We desire a method of electronically controlling the acoustical properties of a room so that one physical space can accommodate various uses. A virtual acoustic room is a room equipped with speakers, microphones and signal processors that functions as an intera...

NSTABILITY of the wVe ring-X chromosome of Drosophila melanogaster is I attributable to anaphase bridge formation during the cleavage mitoses where loss of the bridge from w""/+ embryos results in gynandromorphs or XO males and breakage of the bridge results in lethality (HINTON 1955). Rod-w"" chromosomes derived from unstable wuc ring chromosomes also cause lethality, but are not lost during c...

This work estimated and validated the land surface temperature (LST) from thermal-infrared Channels 4 (10.8 μm) and 5 (12.0 μm) of the Visible and Infrared Radiometer (VIRR) onboard the second-generation Chinese polar-orbiting FengYun-3A (FY-3A) meteorological satellite. The LST, mean emissivity and atmospheric water vapor content (WVC) were divided into several tractable sub-ranges with little...

We propose a new remote gaze tracking system as an intelligent TV interface. Our research is novel in the following three ways: first, because a user can sit at various positions in front of a large display, the capture volume of the gaze tracking system should be greater, so the proposed system includes two cameras which can be moved simultaneously by panning and tilting mechanisms, a wide vie...

Carcass persistence time and detectability are two main sources of uncertainty on roadkill surveys. In this study, we evaluate the influence of these uncertainties on roadkill surveys and estimates. To estimate carcass persistence time, three observers (including the driver) surveyed 114km by car on a monthly basis for two years, searching for wildlife-vehicle collisions (WVC). Each survey cons...

In this paper, we present an “appearance-based” virtual view generation method for temporally-varying events taken by multiple cameras of the “3D Room”, developed by our group. With this method, we can generate images from any virtual view point between two selected real views. The virtual appearance view generation method is based on simple interpolation between two selected views. The corresp...

Personal Communications System (PCS) promises to provide a variety of information exchanges among users with any type of mobility, at any time, in any place, through any available device. To achieve this ambitious goal, two of the major challenges in the system design are: (i) to provide a high speed wireless subsystem with large capacity and acceptable Quality of Service (QoS); and (ii) to des...

The COVID-19 outbreak locked down the university classrooms and transferred teaching learning activities to a virtual space. This paper discusses challenges teachers faced due this dramatic transfer from habitual on-line classes. small-scale empirical research focuses on two questions: Which problems did face, which solutions they find overcome them? study also investigates techniques of synchr...
