Distributed organizations increasingly rely on new video-supported communication technologies that may be subject to transmission delays. These delays systematically misalign the feedback one side receives from the other. Through microanalysis of video data from a video-supported' meeting in a geographically distributed company, we examine the impact of delay in such communication systems We sp...

A remotely controlled microgripper has been developed as an end-eeector for a six-degree-of-freedom force-reeecting motion-scaling system. The microgrip-per is small and lightweight, and features relatively high force and stroke compared to other designs. Furthermore , force sensing enables the accurate measurement and control of tool-tissue forces, and the em-ulation of diierent mechanical dev...

This paper examines the role of visual information in a remote help-giving situation involving the collaborative physical task of designing a prototype remote control. We analyze a set of video recordings captured within an experimental setting. Our analysis shows that using gestures and relevant artefacts and by projecting activities on the camera, participants were able to discuss several des...

ecological studies based on field data have shown that vegetation phenology follows a relatively well-defined temporal pattern. this pattern, that is reflecting the cumulative temperature from the date of the beginning of the growth, can be represented by the use of a suitable model. due to the spatial, temporal, and ecological complexity of these processes a simple method to monitor phenologic...

Single-Display Groupware (SDG) applications use a single display shared by multiple people. This kind of interaction has proven very useful for children, who often share a computer for games and educational software, and also for colocated meetings, where multiple people are in the same room discussing, annotating and editing a design or presentation which is shown on a computer screen. We have...

monitoring and evolution of drought is the first step in any drought management system. in this study, evaluation of a new indexa new method is provided to monitor the severity of drought with remote sensing combined drought index (rcdi). the index is based on the fact that drought is a natural phenomenon caused by a combination of various factors such as a shortage in the amount of precipitati...
