The wide-spread of social media provides unprecedented sources of written language that can be used to model and infer online demographics. In this paper, we introduce a novel visual text analytics system, DemographicVis, to aid interactive analysis of such demographic information based on user-generated content. Our approach connects categorical data(More)
Despite the published benefits of minimally invasive video-assisted thoracoscopic surgery (VATS) for lobectomy, the majority of lobectomies in the United States continue to be performed through a thoracotomy. The low adoption rate of VATS has been attributed to its technical challenges and ergonomic inefficiencies. Robotic surgery has been proposed as an(More)
Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we(More)
Displays supporting stereoscopy and head-coupled motion parallax can enhance human perception of complex 3D datasets. This has been studied extensively for datasets containing 3D surfaces and 3D networks but less for so volumetric data. Volumetric data is characterized by a heavy presence of transparency, occlusion and highly ambiguous spatial structure.(More)
Dynamic view parameter adjustment can reduce visual fatigue issues in stereo displays. In a multi-scale virtual environment, which has geometric details ranging over several orders of magnitude, these adjustments are particularly important. We evaluate how two adjustment techniques interact with 7 degree-offreedom navigation in desktop VR and a CAVE. The(More)
Displays supporting stereoscopic and head-coupled motion parallax can enhance human perception of containing 3D surfaces and 3D networks but less for so volumetric data. Volumetric data is characterized by a heavy presence of transparency, occlusion and highly ambiguous spatial structure. There are many different rendering and visualization algorithms and(More)
This paper presents the concept, working prototype and design space of a two-handed, hybrid spatial user interface for minimally immersive desktop VR targeted at multi-dimensional visualizations. The user interface supports dual button balls (6DOF isotonic controllers with multiple buttons) which automatically switch between 6DOF mode (xyz + yaw,pitch,roll)(More)
