AR may have great potential for aiding safe marine navigation, however the devices currently available have significant limitations that prevent them from being practical for marine usage. While suitable devices are still a few years away from the market, we propose that research into AR-aided marine navigation can and should be conducted now. Towards this goal, we have developed a virtual reality simulation system that allows us to experiment with a range of possible AR devices and information overlays within a dynamic and highly flexible ship simulation. This strategy avoids challenging registration issues and being tied to any particular prototype AR hardware. The project{\textquoteright}s goals include identifying the technical specifications required for future AR devices to be useful in navigation, what information is most beneficial to display, and what types of visual representations are best for conveying that information. }, keywords = {augmented reality, navigation, virtual reality, Visualization}, author = {Butkiewicz, Thomas} } @article {6376, title = {Visualization of Nautical Information (VONI) Workshop 2017}, year = {2017}, month = {12/7/2016}, pages = {2}, institution = {International Hydrographic Organization}, address = {Monaco}, abstract = {

At the NIPWG2 meeting the question was raised \“once the standards are in place how will the Hydrographic Offices (HO) implement them?\” The answer was silence and a shrug of the shoulders. It was then proposed by UNH to host a workshop to help each HO answer that question with confidence and direction.

Previous perceptual research and human factors studies have identified several effective methods for texturing 3D surfaces to ensure that their curvature is accurately perceived by viewers. However, most of these studies examined the application of these techniques to static surfaces. This paper explores the effectiveness of applying these techniques to dynamically changing surfaces. When these surfaces change shape, common texturing methods, such as grids and contours, induce a range of different motion cues, which can draw attention and provide information about the size, shape, and rate of change. A human factors study was conducted to evaluate the relative effectiveness of these methods when applied to dynamically changing pseudo-terrain surfaces. The results indicate that, while no technique is most effective for all cases, contour lines generally perform best, and that the pseudocontour lines induced by banded color scales convey the same benefits.

Hurricanes generate massive amounts of marine\ debris in coastal waterways, causing environmental problems\ and hazards to safe navigation. Before debris can be removed,\ they must be located and identified, a tedious and timeconsuming process. Automatic target recognition algorithms\ speed up this process by searching vast swaths of survey data to\ locate anomalies that could be debris. However, these targets\ must still be manually evaluated by analysts. We present a tool\ that increases analysts\’ efficiency by automating most of the\ interaction steps involved in marine debris evaluation. It\ automatically generates and displays multiple optimal views,\ which can remove the need for analysts to manually reposition\ their viewpoint. We also applied these optimal views to a webbased crowdsourcing application, which tested whether the\ general public could assist in marine debris evaluation. Our\ results showed that, even though the participants were\ untrained, their collective decisions were generally in agreement\ and reliable enough to greatly reduce the number of marine\ debris targets that must be evaluated by the limited pool of\ trained analysts. This has the potential to increase analytical\ capacity in time-critical disaster response situations.

Cutting planes have long been an effective tool for\ visualizing discrete slices of 3D vector fields. The\ following research-in-progress focusses on evaluating a\ variety of cutting plane rendering techniques at various\ seeding densities to find those conditions which provide superior perceptual cues for accurately estimating the\ direction of flow through a point on a cutting plane.
