    The Lack of Specialized Symbology and Visual Interaction Design Guidance for Sub-Sea Military Operations
    (The Eurographics Association, 2023) Walsh, Gareth; Sindlev Andersen, Nicklas; Stoianov, Nikolai; Jänicke, Stefan; Gillmann, Christina; Krone, Michael; Reina, Guido; Wischgoll, Thomas
    This paper addresses the lack and need for specialized and visually effective interaction design guidance for sub-sea military operations. We identify gaps in the implementation of best practice visualization techniques, building upon our recently published survey on visual interfaces used in military decision support systems. Our analysis focuses on the current NATO symbology standard and several sub-sea military frontend systems to identify deficiencies and their underlying causes. Such origins of deficiencies include inadequate design consideration of environmental conditions, as well as incomplete hardware and software requirements for sub-sea conditions. While many such gaps exist, for the purposes of this paper, we narrow our focus to exploring the potential for a new sub-sea symbology for the maritime domain, drawing from insights gained and developed through our participation in the EDIDP (European Defence Industrial Development Programme) project CUIIS (Comprehensive Underwater Intervention Information System). We propose extending existing NATO military standards by creating a comprehensive framework for a new sub-sea symbology and visual interaction design. This framework includes a set of semiotic communication symbols for military divers, which can easily be combined based on the most common messages required for effective communication between command and military divers. This paper concludes by highlighting the opportunities for improvement in NATO Military Symbology for sub-sea military operations.

    Lessons Learned from Large Data Visualization Software Development for the K computer
    (The Eurographics Association, 2020) Nonaka, Jorji; Sakamoto, Naohisa; Gillmann, Christina and Krone, Michael and Reina, Guido and Wischgoll, Thomas
    High Performance Computing (HPC) always had a close relationship with visualization as we can remember the landmark report on ''Visualization in Scientific Computing'', which was credited to have coined the term Scientific Visualization (SciVis). K computer, a Japanese flagship HPC system, appeared in 2011 as the most powerful supercomputer in the Top500 list, and as other similar HPC systems in that ranking, it was designed to enable ''Grand Challenge'' scientific computing with unprecedented scale and size. RIKEN Center for Computational Science (RIKEN R-CCS) operated and provided the K computer's computational resources to the HPC community for almost 8 years until it was decommissioned in 2019. Considering that most of the scientific computing results were publicly presented in the form of visual images and movies, we can infer that the SciVis was widely applied for assisting the domain scientists with their end-to-end scientific computing workflows. In addition to the traditional visualization applications, various others large data visualization software development were conducted in order to tackle the increased size and amount of the simulation outputs. RIKEN R-CCS participated in some of these development and deployment dealing with several environmental and human factors. Although we have no precise statistics regarding the visualization software usage, in this paper, we would like to present some findings and lessons learned from the large data visualization software development in the K computer environment.

    Physical Traces and Digital Stories: Exploring the Connections Between Forensics and Visualization
    (The Eurographics Association, 2022) Schetinger, Victor; Salisu, Saminu; Gillmann, Christina; Krone, Michael; Reina, Guido; Wischgoll, Thomas
    Forensics, or forensic science, deals with the analysis of evidence for investigation. It is a a wide and strongly interdisciplinary field that needs the coupling of research, practice, and communication to be useful. New techniques have to be constantly developed and applied in the field to solve social conflicts. Recent work suggests, however, that there are many gaps in this coupling, and we argue that there are lessons to be learned from them. Among the difficulties faced by forensics are the management of its interdisciplinarity and over-specialization, and the effective adoption of new research, which are also pressing for the visualization community. In this paper, we bring a gentle introduction to the challenges of forensics with a focus on its digital forms and explore connections to visualization. We believe these connections can be leveraged to further the development of both fields, and particularly that visualization and interaction are critical for the forensics process.
