....from the subjects are listed in Table 2. After performing a Wilcoxon Signed Ranks Test on data in Table 2, we conclude that the control interface shown in Figure 5 is easier to use than the interface shown in Figure 9 at the p = 0.05 significance level. Besides this experiment, we note the work in [12] which also supports the interface design for FlySPEC. 3.2 Experiment on Serving the Audience with a PTZ Camera and a Panoramic Camera In this paper, we argued for benefits of a system combining both a PTZ camera and a panoramic camera. Is it a good solution for a video server The experiment in ....

....teleconferencing applications are designed for the one on one scenario that limits the capture of a video stream to a single sensor and the display to a CRT or flat panel device. While widely used, this one on one interface does not provide a compelling or convincing presence to the participants [14]. Most group teleconferencing systems in use today are simply versions of the one to one system used by a group of people at each site. Such single camera single display systems usually suffer from low resolution, small fields of view, and smaller than life size dis plays. Attempts to overcome ....

....awareness often made the user unaware of important activity taking place out of view. To provide users with such context in addition to a detailed, high resolution view, we investigated the simultaneous display of a detailed view, linked to its position within a wideangle (global) view [11]. Conclusions and Lessons Learned Since the system was in flux during development, only ad hoc observational evaluation has thus far been performed, but we anticipate objective user studies in the near future. Early feedback encourages our belief that the Reactive Environment approach offers ....

....interaction from the user in order to make a full two way audio video connection. When the door was shut, glances were not authorized and further interaction was required to establish a two way audio video connection. When the door was locked, no video connections were possible. Yamaashi et al. [Yam96] describe another extension in which users were given two views: a wide angle view to show the context of the office and a more detailed shot linked seamlessly together. They also explored the use of sensors placed in the physical environment to provide contextual cues to remote users of the media ....

....a limited backup to the desktop input device. ffl A second, smaller window provides live video from a bird s eye view of the operating room. Controls on the window allow the surgeon to pan the camera in 4 directions as well as zoom. The window is also equipped with a point and click interface [15]. If the surgeon clicks (or touches) any point on the O R video, the camera will automatically center that point. The surgeon can specify a region to zoom to by sweeping out a box on the O R video window using the mouse or touchscreen. ffl Two more windows provide views of the patient s MRI data ....

....perceptual bandwidth may be unimportant for loosely coupled activities, it becomes vital for conjoint actions such as V phone connections and tele explorations. Multiple views on remote sites improve the information bandwidth of a single static channel, but require the user to link different views [3, 7]. Another approach is the concept of Virtual Window in which a remote camera is slaved to a person s head movements [4] However, the lack of robustness of the vision technique developed in [4] image differencing, assumption of upright head angle) imposes restrictions on the user. In CoMedi, we ....

In CoMedi, we have designed Fovea to resolve the problem of discontinuity apparent in Extra Eyes [7]. In addition, we have developed a face tracker that integrates multiple computer vision techniques to provide the robustness and efficiency imposed by human requirements. Figure 1. On the left, the zoomed in circular fovea; on the right, the rectangular fovea with a low zoom factor. Fovea An ....
