| Virtual Bounds: a teleoperated mixed reality |
|
| Abstract: This paper introduces a mixed reality workspace that allows users to combine physical and computer-generated artifacts, and to control and simulate them within one fused world. All interactions are captured, monitored, modeled and represented with pseudo-real world physics. The objective of the presented research is to create a novel system in which the virtual and physical world would have a symbiotic relationship. In this type of system, virtual objects can impose forces on the physical world and physical world objects can impose forces on the virtual world. Virtual Bounds is an exploratory study allowing a physical probe to navigate a virtual world while observing constraints, forces, and interactions from both worlds. This scenario provides the user with the ability to create a virtual environment and to learn to operate real-life probes through its virtual terrain.

| Wipe-Off: an intuitive interface for exploring ultra-large multi-spectral data sets for cultural heritage diagnostics |
| Abstract: A visual analytics technique for the intuitive, hands-on analysis of massive, multi-dimensional and multi-variate data is presented. This multi-touch-based technique introduces a set of metaphors such as wiping, scratching, sandblasting, squeezing and drilling, which allow for rapid analysis of global and local characteristics in the data set, accounting for factors such as gesture size, pressure and speed. A case study is provided for the analysis of multi-spectral image data of cultural artefacts. By aligning multi-spectral layers in a stack, users can apply different multi-touch metaphors to investigate features across different wavelengths. With this technique, flexibly definable regions can be interrogated concurrently without affecting surrounding data.

| VideoBlaster: a distributed, low-network bandwidth method for multimedia playback on tiled display systems |
| Abstract: Tiled display environments present opportune workspaces for displaying multimedia content. Often times, displaying this kind of audio/visual information requires a substantial amount of network bandwidth. In this paper we present a method for distributing the decoding over the entire display environment, allowing for substantially less network overhead. This method also allows for interactive configuration of the visual workspace. The method described scales independently of video frame size and produces lower latency compared to streaming approaches.

| Giga-Stack: A Method for Visualizing Giga-pixel Layered Imagery on Massively Tiled Displays |
| Abstract: In this paper, we present a technique for the interactive visualization and interrogation of multi-dimensional giga-pixel imagery. Co-registered image layers representing discrete spectral wavelengths or temporal information can be seamlessly displayed and fused. Users can freely pan and zoom, while swiftly transitioning through data layers, enabling intuitive analysis of massive multi-spectral or time-varying records. A data resource aware display paradigm is introduced which progressively and adaptively loads data from remote network attached storage devices. The technique is specifically designed to work with scalable, high-resolution, massively tiled display environments. By displaying hundreds of mega-pixels worth of visual information all at once, several users can simultaneously compare and contrast complex data layers in a collaborative environment.

| DIGI-Vis: Distributed Interactive Geospatial Information Visualization |
| Abstract: Geospatial information systems provide an abundance of information for researchers and scientists. Unfortunately this type of data can usually only be analyzed a few megapixels at a time, giving researchers a very narrow view into these voluminous data sets. We propose a distributed data gathering and visualization system that allows researchers to view these data at hundreds of megapixels simultaneously. This system allows scientists to view real-time geospatial information at unprecedented levels expediting analysis, interrogation, and discovery.

| CGLXTouch: A multi-user multi-touch approach for ultra-high-resolution collaborative workspaces |
| Abstract: This paper presents an approach for empowering collaborative workspaces through ultra-high-resolution tiled display environments concurrently interfaced by multiple multi-touch devices. Multi-touch table devices are supported along with portable multi-touch tablet and phone devices, which can be added to and removed from the system on the fly. Events from these devices are tagged with a device id and are synchronized with the distributed display environment enabling multi-user support. As portable devices are not equipped to render content directly, a rendered viewpoint is streamed in. The presented approach scales for large numbers of devices, providing a multitude of hands-on techniques for collaborative data analysis.
