These difficulties arise because the available data contains inaccuracies, has high-dimensionality and has a high degree of uncertainty. Currently these difficulties are intensified by the lack of computational tools to support interactive visual interpretation and integration of geophysical data leading to robust structural models of the reservoir and its parameters. To address these difficulties domain experts are demanding better and more detailed visualization tools to help them as they explore their data. In this paper, we present a tool that contains a set of interactive visualizations that combines, merges and extends existing visualization techniques. We describe the iterative design process we undertook to develop the tool, relying on insight from domain specialists. Our tool supports 3D spatial analysis and exploration of the data with a set of manipulations designed to provide domain experts with insights into their highly complex microseismic data. Our microseismic visual-analysis tool also provides an extended parallel coordinates implementation to: (1) support interactive filtering and selection through combined filter and shadow boxes that can remove the uninteresting events from further analysis, (2) correlate between the data attributes by axes reordering and outlier discovery, and (3) visually correlate the data events rendering through additional visual elements such as color maps. Our multiple coordinated views link the insights gained from one view with other views instantaneously. We conclude with a discussion of the feedback provided to us by the domain experts.

Users can view and interact with mixed reality datasets on their mobile device, such as a tablet or smartphone, from distances both far and very near to the tabletop. We implement the tracking system in the context of a collaborative reservoir engineering tool that brings together many experts who need a private workspace to interact with unique datasets, which is supported by our system.

Our paper presents the design and prototyping of Spidey, a robotic assistant on a tabletop environment which works together as a team member with its human companions, aware of their tabletop actions and reacting or initiating tabletop actions according to the task requirements. Spidey is designed both as a proof of concept, suggesting the benefits, and reflecting on the limitations of a robotic assistant in an interactive reservoir engineering tabletop visualization application we are implementing. This paper motivates our concept of a robotic tabletop assistant, and outlines our design efforts and the current Spidey prototype Thu, 23 Feb 2012 21:43:25 GMT http://hdl.handle.net/1880/48908 2012-02-23T21:43:25Z http://hdl.handle.net/1880/48905 Title: "Designing Video Games with Social, Physical, and Authorship Gameplay Authors: Lapides, Paul; Sharlin, Ehud; Costa Sousa, Mario Abstract: "Today's video games have undergone many changes that have turned them from niche hobbies into ubiquitous and popular activities. Modern games now utilize physical interaction as the primary modality for controlling the game, they have become more casual and social activities, and they have enabled players to express their creativity through the authorship of content. In this thesis, we investigate the use of physical interaction, socialization, and authorship of content in the design of video games. We have created a design framework that can be used as a guide for designing new games and have designed three games to investigate the successes and limitations of each of the three themes: Film Karaoke, Joke's On You, and Social Comics. Through our evaluation of Social Comics, we have come to conclude that physicality, sociability, and authorship are powerful design themes for enhancing the player's experience and for creating new forms of gameplay."
