    Similarity-based Exploded Views

    Exploded views are often used in illustration to overcome the problem of occlusion when depicting complex structures. In this paper, we propose a volume visualization technique inspired by exploded views that partitions the volume into a number of parallel slabs and shows them apart from each other. The thickness of slabs is driven by the similarity between partitions. We use an information-theoretic technique for the generation of exploded views. First, the algorithm identifies the viewpoint from which the structure is the highest. Then, the partition of the volume into the most informative slabs for exploding is obtained using two complementary similarity-based strategies. The number of slabs and the similarity parameter are freely adjustable by the user

    Streaming and 3D mapping of agri-data on mobile devices

    Farm monitoring and operations generate heterogeneous AGRI-data from a variety of different sources that have the potential to be delivered to users ‘on the go’ and in the field to inform farm decision making. A software framework capable of interfacing with existing web mapping services to deliver in-field farm data on commodity mobile hardware was developed and tested. This raised key research challenges related to: robustness of data steaming methods under typical farm connectivity scenarios, and mapping and 3D rendering of AGRI-data in an engaging and intuitive way. The presentation of AGRI-data in a 3D and interactive context was explored using different visualisation techniques; currently the 2D presentation of AGRI- data is the dominant practice, despite the fact that mobile devices can now support sophisticated 3D graphics via programmable pipelines. The testing found that WebSockets were the most reliable streaming method for high resolution image/texture data. From our focus groups there was no single visualisation technique that was preferred demonstrating that a range of methods is a good way to satisfy a large user base. Improved 3D experience on mobile phones is set to revolutionize the multimedia market and a key challenge is identifying useful 3D visualisation methods and navigation tools that support the exploration of data driven 3D interactive visualisation frameworks for AGRI-data

    Task-based Adaptation of Graphical Content in Smart Visual Interfaces

    To be effective visual representations must be adapted to their respective context of use, especially in so-called Smart Visual Interfaces striving to present specifically those information required for the task at hand. This thesis proposes a generic approach that facilitate the automatic generation of task-specific visual representations from suitable task descriptions. It is discussed how the approach is applied to four principal content types raster images, 2D vector and 3D graphics as well as data visualizations, and how existing display techniques can be integrated into the approach.Effektive visuelle Repräsentationen müssen an den jeweiligen Nutzungskontext angepasst sein, insbesondere in sog. Smart Visual Interfaces, welche anstreben, möglichst genau für die aktuelle Aufgabe benötigte Informationen anzubieten. Diese Arbeit entwirft einen generischen Ansatz zur automatischen Erzeugung aufgabenspezifischer Darstellungen anhand geeigneter Aufgabenbeschreibungen. Es wird gezeigt, wie dieser Ansatz auf vier grundlegende Inhaltstypen Rasterbilder, 2D-Vektor- und 3D-Grafik sowie Datenvisualisierungen anwendbar ist, und wie existierende Darstellungstechniken integrierbar sind

    Coherent Label Placement for 3D Exploded View

    The use of labels in images represents the basics of visual object presentations that we are all familiar with. However, few know that automatic label placement in 2D or 3D space belongs to the set of NP-complete and NP-hard problems. While state-of-the-art algorithms such as hedgehog labeling already produce incredible coherent results in real-time interactive applications, they were only designed for static and non-deformable objects. Therefore, their performance decreases when combined with the dynamic and model-deforming the 3D model presentation techniques such as exploded diagrams a.k.a. exploded views, which present the structure of 3D model by "exploding" their parts. We propose an extension of hedgehog labeling to work with exploded views by introducing clustering of model exploded parts and their labels. Clustered hedgehog labeling uses the explosion information to separate 3D space into sections belonging to individual label clusters, each running hedgehog labeling instances solely on the cluster members. The evaluation of the proposed solution and its Textplosion implementation was done by running a usability study enhanced with eye-tracking on a group of volunteers, where improvement of the original algorithm was detected. The need for 3D test models for experimentation resulted in the creation of a 3D Labeling dataset to be shared with the community in an attempt to fill the void of a missing standardized dataset for 3D labeling algorithms

    New amusement rides: Platforms for parents and children to share fun

    Get PDF
    Since Bakken, the world\u27s first amusement park, opened in 1583 at Klampenborg, Denmark, amusement parks have become a fun place for people to spend quality time with family. Early versions of American amusement parks in the United States entertained patrons by providing picnic groves, concert halls and events like fireworks. However, with the rapid evolution of technology, the primary characteristic of many of today\u27s parks are rides which are, first and foremost, breathtaking. In other words, amusement parks tend to gratify a desire for thrills rather than provide a space for parents and children to enjoy spending time and playing together. My thesis proposes a way to make the amusement park a place for play where parents and children share fun together. I design two rides which target six- to twelve-year-olds and their parents, and enable them to positively interact and collaborate with each other. After conducting research, including field trips to experience firsthand current amusement rides, a study of middle childhood development, and a questionnaire collecting people\u27s perception of play, I design Carstruction and Spacejump to satisfy people\u27s desire for true play. It is my intent for riders to play an active role and provide certain interactions between the riders in order for the ride to function. This cooperative dynamic encourages child development as well as parent-child relationships. Operating instructions and computer-generated scenarios are illustrated, and a semi-scale mockup of a ride is fabricated for an evaluation of its feasibility in terms of technology, marketability, and legality. Following a trial ride, users\u27 feedback is documented and inspires future design revision
