Underwater Window: High Definition Video on VENUS and NEPTUNE

A joint McGill -University of Victoria team is deploying a high definition video camera on the VENUS project node in the Saanich Inlet and will be using the experience gained to deploy similar cameras on the NEPTUNE project network. Underwater HD camera selection is discussed for both scientific research and public outreach. Low light level capability and an extended lens zoom range enable the study of small invertebrate behaviour. A unique camera control user interface was designed that will allow scientists to see a large scale map of their sites of interest while the camera is zoomed in on one particular site. Camera control software challenges included designing a system that would simultaneously control the camera, two sets of lighting and the pan/tilt, which are separate devices, from a single user interface over a shared network. A camera support and control system was designed and deployed. The high definition camera and zoom lens are mounted in a pressure canister on a large support frame that has an integrated camera pan/tilt mechanism. There are two types of illumination and a set of lasers that project reference lines for gauging object size. The entire camera system is connected to the VENUS node using a wet-mate hybrid connector (copper and fiber optic). The paper also discusses the deployment of the camera and support structure in Saanich Inlet and the subsequent connection to the VENUS node.

“…With the manner in which co-located groups are presented and perceived by others receiving greater attention, research provides an indication of possible technical solutions to increased awareness of another's gaze through camera placement and technologies [8,9]. Other work addresses display navigation or overall video conference set up [10,11].…”

In mixed presence settings (MPS) computer-mediated interactions of individuals and co-located groups, particular technical (video transmission of a large co-located group) and perceptual (ability to perceive video of remote people) challenges require attention. This paper presents results of a descriptive study within industry based on in vivo screen snapshots. The results illustrate how MPS are complicated by size of co-located groups. We present considerations for using video in these settings, informing engineers, evaluators and users of such potentially complex videoconferencing spaces.

“…The motivation for Fovea is to avoid the visual discontinuity due to the split screen solution adopted in Extra-Eyes (Yamaashi, 1996). In Extra-eyes, a low resolution camera provides the observer with a wide angle view of the remote site.…”

Abstract:Mediaspaces have been designed to facilitate informal communication and support group awareness while assuring privacy protection. However, low bandwidth communication is a source of undesirable discontinuities in such systems, resulting in a loss of peripheral awareness. In addition, privacy is often implemented as an accessibility matrix coupled to an all-or-nothing exposure of personal state. In this article, we describe CoMedi, a mediaspace prototype that addresses the problem of discontinuity and pri vacy in an original way: computer vision and speech recognition are used in conjunction to minimize visual discontinuities while supporting free movements in a room. Publication filters maintain privacy at the desired level of transparency.
