Investigation of Membrane Computing for Generative Computer Graphics
No full textIn order to explore new methods of generative graphics, we have explored the use of the relatively new computing paradigm known as Membrane Computing. Similar to the oft-used technique known as Lindenmeyer Systems (L- Systems), Membrane Computing shows potential as being a more powerful tool for generating graphics.Wagy, Mark; McDermott, James; Keefe, Daniel F..

Toward Simulation-Based Medical Device Design: Integrating High Performance Cloud FEA Computing Into Intuitive Design Modeling
No full textposterWe present a new approach to simulation-based medical device design by integrating current CAD and FEA systems and developing natural human-computer interfaces to control the resulting integrated system. In order to utilize the high performance FEA computing power, a network communication program was developed and a Python script was used to initialize simulations and read calculated results. A complete design process of a breast biopsy cannula was demonstrated.Minnesota Supercomputing InstituteLin, Chi-Lun; Coffey, Dane; Erdman, Arthur; Keefe, Daniel. (2012).

Touching the 3rd Dimension (Dagstuhl Seminar 12151)
No full textIn recent years interactive visualization of 3D data has become important and widespread due to the requirements of several application areas.
However, current user interfaces often lack adequate support for 3D interactions: 2D desktop systems are often limited in cases where natural interaction with 3D content is required, and 3D user interfaces consisting of stereoscopic projections and tracked input devices are rarely adopted by ordinary users. Touch interaction has received considerable attention for 2D interfaces, and more recently for 3D interfaces.
Many touch devices now support multiple degrees of freedom input by capturing multiple 2D contact positions on the surface as well as varying levels of pressure and even depth. There is great potential for multi-touch interfaces to provide the traditionally difficult to achieve combination of natural 3D interaction without any instrumentation. When combined with a stereoscopic display as well as depth cameras, we believe that multi-touch technology can form the basis for a next generation of 3D user interfaces. Several research groups have begun to explore the potential, limitations, and challenges of this and other 3D touch environments, and first commercial systems are already available.
The goal of the seminar "Touching the 3rd Dimension (T3D)" is to address the research and industrial challenges involved in exploring the space where the flat digital world of surface computing meets the physical, spatially complex, 3D space in which we live.
The seminar will provide a common forum to attract groups of conference attendees who share their visions of the future and recent results in the area of improving 3D interaction and visualization by taking advantage of the strengths of advanced multi-touch computing
BioWIM: A MultiSurface, MultiTouch Interface for Exploratory Visualization of Biomedical Data
No full textThis paper presents the BioWIM, a multi-surface, multi-touch interface for exploring visualizations of complex biomedical environments using a semi-immersive virtual reality (VR) display. The BioWIM reinterprets the traditional world-in-miniature (WIM) VR metaphor within the context of navigating visualizations based on medical imaging data and using the unique capabilities provided by coupling a multi-touch table with a stereoscopic display wall. A "Window to the World" metaphor is used to navigate a detailed 3D scene displayed on the vertical surface by manipulating widgets and making touch gestures on top of medical imaging data displayed on the table. The technique supports navigation through complex environments while maintaining context. The results of a controlled user study comparing the BioWIM to a more traditional touch interface demonstrate improvements in accuracy in a compound search and size judgment task when using the BioWIM. An interpretation of these results and discussion of design principles and lessons learned is presented.Coffey, Dane; Keefe, Daniel F.. (2010).

Visualizing Ancient Greek Rhetoric in Immersive Virtual Reality
No full textposterThe goal of this project is to reconstruct ancient Greek rhetorical sites in virtual environments, including simulating architecture, sound, crowds, to better understand how the physical settings structured and constrained the interactions that took place in them. Our work makes use of the large-format, head-tracked stereoscopic display at MSI, and our preliminary results include an immersive visualization of the Thersilion at Megalopolis, a site where speeches were once given to 10,000 people.Minnesota Supercomputing InstituteKim, Kyungyoon; Jackson, Bret; Thorson, Lauren; Graff, Richard; Rabbani, Azadeh; Johnstone, Christopher L.; Keefe, Daniel F..

Conceptual room for ontic vagueness
No full textThis thesis is a systematic investigation of whether there might be conceptual room for the idea that the world itself might be vague, independently of how we describe it. This idea – the existence of so-called ontic vagueness – has generally been extremely unpopular in the literature; my thesis thus seeks to evaluate whether this ‘negative press’ is justified. I start by giving a working definition and semantics for ontic vagueness, and then attempt to show that there are no conclusive arguments that rule out vagueness of this kind. I subsequently establish what type of arguments I think would be most effective in establishing ontic vagueness and provide some arguments of this form. I then highlight a potential worry for this type of argument, but argue that it can be circumvented. Finally, I consider the main ways that the opponent of ontic vagueness would be likely resist the arguments I have offered, and argue that these strategies of response are methodologically problematic. I conclude by claiming that ontic vagueness is a perfectly plausible ontological commitment
