Visual Arguments and Moral Causes in Charity Advertising: Ethical Considerations

Social advertising often employs persuasive imagery in support of a morally laden cause. These visual arguments can take the form of veridical representations of the given situation or the form of purposeful visual blends. Both visual routes to persuasion have serious ethical issues to confront. In what concerns the purportedly veridical images, controversies about picture retouching and framing have cast many doubts on their success in offering unmediated access to a given reality. Editorial interests have proven far too influential on the destiny of what and how is presented to the audience from the amount of visual material available on a topic. Even when the audience is certain that photos are not doctored, the use of veridical images may be seen as unethical. Their disproportionate affective impact may lead the audience to hold biased opinions, since other concerns may be impossible to capture in a vivid picture. Visual blends may be the answer to this problem, employing the fictional or the figurative to help the viewer grasp the moral anatomy of a given situation. Their generous use of figurative meaning may be seen as their strength and their weakness at the same time. It makes them less likely to face accusations of distorting reality, because they do not claim to be windows on reality per se. At the same time, it makes them vulnerable to interpretations that miss their true point – one might appreciate the artistry of a visual metaphor or a visual pun and fail to consider the statement it makes about a given situation. Contemporary philosophical approaches to the place of visuals in moral persuasion inform my analysis of the use of visual arguments in charity-oriented advertising

Exploring the Potential of 3D Visualization Techniques for Usage in Collaborative Design

Best practice for collaborative design demands good interaction between its collaborators. The capacity to share common knowledge about design models at hand is a basic requirement. With current advancing technologies gathering collective knowledge is more straightforward, as the dialog between experts can be supported better. The potential for 3D visualization techniques to become the right support tool for collaborative design is explored. Special attention is put on the possible usage for remote collaboration. The opportunities for current state-of-the-art visualization techniques from stereoscopic vision to holographic displays are researched. A classification of the various systems is explored with respect to their tangible usage for augmented reality. Appropriate interaction methods can be selected based on the usage scenario

Discrete event simulation and virtual reality use in industry: new opportunities and future trends

This paper reviews the area of combined discrete event simulation (DES) and virtual reality (VR) use within industry. While establishing a state of the art for progress in this area, this paper makes the case for VR DES as the vehicle of choice for complex data analysis through interactive simulation models, highlighting both its advantages and current limitations. This paper reviews active research topics such as VR and DES real-time integration, communication protocols, system design considerations, model validation, and applications of VR and DES. While summarizing future research directions for this technology combination, the case is made for smart factory adoption of VR DES as a new platform for scenario testing and decision making. It is put that in order for VR DES to fully meet the visualization requirements of both Industry 4.0 and Industrial Internet visions of digital manufacturing, further research is required in the areas of lower latency image processing, DES delivery as a service, gesture recognition for VR DES interaction, and linkage of DES to real-time data streams and Big Data sets

Spatial calibration of an optical see-through head-mounted display

We present here a method for calibrating an optical see-through Head Mounted Display (HMD) using techniques usually applied to camera calibration (photogrammetry). Using a camera placed inside the HMD to take pictures simultaneously of a tracked object and features in the HMD display, we could exploit established camera calibration techniques to recover both the intrinsic and extrinsic properties of the~HMD (width, height, focal length, optic centre and principal ray of the display). Our method gives low re-projection errors and, unlike existing methods, involves no time-consuming and error-prone human measurements, nor any prior estimates about the HMD geometry

From Analog to Virtual: Visual Stylizations of Humanoid Characters Across Media

Visual stylization and its impact on different aspects of the perception of digital human beings are commonly debated. This study investigated how fictional and non-fictional characters are represented in various media from the perspective of digital humanoid character design. Based on Zangwill's theory of Moderate Aesthetic Formalism, this study focused on the formalistic aspect of visual analysis and interpretation of media artifacts ranging from older media such as paintings to newer media, such as animations, interactive video games and mobile apps. This paper also explores several case studies of how humanoid digital characters are represented via visual stylizations across different media. This article underlines the importance of visual stylization as an opportunity to find unique and innovative ways of communicating with visual means

Engaging the Virtual Landscape: Toward an Experiential Approach to Exploring Place Through a Spatial Experience Engine

The utilization of Geographic Information Systems (GIS) and other geospatial technologies in historical inquiry and the humanities has led to a number of projects that are exploring digital representations of past landscapes and places as platforms for synthesizing and representing historical and geographic information. Recent advancements in geovisualization, immersive environments, and virtual reality offer the opportunity to generate digital representations of cultural and physical landscapes, and embed those virtual landscapes with information and knowledge from multiple GIS sources. The development of these technologies and their application to historical research has opened up new opportunities to synthesize historical records from disparate sources, represent these sources spatially in digital form, and to embed the qualitative data into those spatial representations that is often crucial to historical interpretation.;This dissertation explores the design and development of a serious game-based virtual engine, the Spatial Experience Engine (SEE), that provides an immersive and interactive platform for an experiential approach to exploring and understanding place. Through a case study focused on the late nineteenth-century urban landscape of Morgantown, West Virginia, the implementation of the SEE discussed in this dissertation demonstrates a compelling platform for building and exploring complex, virtual landscapes, enhanced with spatialized information and multimedia. The SEE not only provides an alternative approach for scholars exploring the spatial turn in history and a humanistic, experiential analysis of historical places, but its flexibility and extensibility also offer the potential for future implementations to explore a wide range of research questions related to the representation of geographic information within an immersive and interactive virtual landscape
