Native advertising : attitudes, value and purchase intention

textNative-form advertising in the digital space can most easily be defined as promotional content constructed to mimic the form and structure of the website that it is embedded on. With the rise of user generated content and social media, digital native advertising is fast becoming a popular promotional tactic for brands looking to engage with an online audience. This study examines whether this form of advertising significantly impacts consumer attitudes towards the ad, value of the ad and purchase intention of the promoted product across three product categories. Although not significant, results suggest that native advertising positively impacts entertainment- and lifestyle-based products, while information-based service industries, including cyber security, saw a negative reaction from respondents. That said, product category did influence attitude toward the ad and ad value regardless of the ad type. Moreover, a strong positive correlation between product involvement and purchase intention was found, indicating the need to target specific audiences with online native advertising.Advertisin

Supporting Focus and Context Awareness in 3D Modelling Tasks Using Multi-Layered Displays

Most 3D modelling software have been developed for conventional 2D displays, and as such, lack support for true depth perception. This contributes to making polygonal 3D modelling tasks challenging, particularly when models are complex and consist of a large number of overlapping components (e.g. vertices, edges) and objects (i.e. parts). Research has shown that users of 3D modelling software often encounter a range of difficulties, which collectively can be defined as focus and context awareness problems. These include maintaining position and orientation awarenesses, as well as recognizing distance between individual components and objects in 3D spaces. In this paper, we present five visualization and interaction techniques we have developed for multi-layered displays, to better support focus and context awareness in 3D modelling tasks. The results of a user study we conducted shows that three of these five techniques improve users' 3D modelling task performance

Hybrid visibility compositing and masking for illustrative rendering

In this paper, we introduce a novel framework for the compositing of interactively rendered 3D layers tailored to the needs of scientific illustration. Currently, traditional scientific illustrations are produced in a series of composition stages, combining different pictorial elements using 2D digital layering. Our approach extends the layer metaphor into 3D without giving up the advantages of 2D methods. The new compositing approach allows for effects such as selective transparency, occlusion overrides, and soft depth buffering. Furthermore, we show how common manipulation techniques such as masking can be integrated into this concept. These tools behave just like in 2D, but their influence extends beyond a single viewpoint. Since the presented approach makes no assumptions about the underlying rendering algorithms, layers can be generated based on polygonal geometry, volumetric data, point-based representations, or others. Our implementation exploits current graphics hardware and permits real-time interaction and rendering.publishedVersio

Design Guidelines for Agent Based Model Visualization

In the field of agent-based modeling (ABM), visualizations play an important role in identifying, communicating and understanding important behavior of the modeled phenomenon. However, many modelers tend to create ineffective visualizations of Agent Based Models (ABM) due to lack of experience with visual design. This paper provides ABM visualization design guidelines in order to improve visual design with ABM toolkits. These guidelines will assist the modeler in creating clear and understandable ABM visualizations. We begin by introducing a non-hierarchical categorization of ABM visualizations. This categorization serves as a starting point in the creation of an ABM visualization. We go on to present well-known design techniques in the context of ABM visualization. These techniques are based on Gestalt psychology, semiology of graphics, and scientific visualization. They improve the visualization design by facilitating specific tasks, and providing a common language to critique visualizations through the use of visual variables. Subsequently, we discuss the application of these design techniques to simplify, emphasize and explain an ABM visualization. Finally, we illustrate these guidelines using a simple redesign of a NetLogo ABM visualization. These guidelines can be used to inform the development of design tools that assist users in the creation of ABM visualizations.Visualization, Design, Graphics, Guidelines, Communication, Agent-Based Modeling

MoSculp: Interactive Visualization of Shape and Time

We present a system that allows users to visualize complex human motion via 3D motion sculptures---a representation that conveys the 3D structure swept by a human body as it moves through space. Given an input video, our system computes the motion sculptures and provides a user interface for rendering it in different styles, including the options to insert the sculpture back into the original video, render it in a synthetic scene or physically print it. To provide this end-to-end workflow, we introduce an algorithm that estimates that human's 3D geometry over time from a set of 2D images and develop a 3D-aware image-based rendering approach that embeds the sculpture back into the scene. By automating the process, our system takes motion sculpture creation out of the realm of professional artists, and makes it applicable to a wide range of existing video material. By providing viewers with 3D information, motion sculptures reveal space-time motion information that is difficult to perceive with the naked eye, and allow viewers to interpret how different parts of the object interact over time. We validate the effectiveness of this approach with user studies, finding that our motion sculpture visualizations are significantly more informative about motion than existing stroboscopic and space-time visualization methods.Comment: UIST 2018.

Best practice of digital government in emerging democracies: Illustrations, challenges and reflections of state building processes

Digital government applications and models of-ten add layers to existing structures, organizations, and routines to facilitate public services. In most states digital government is thus added to established structures and organizations, but what hap-pens when e-government develop at as an integrated part of new state building? This is the overall question in this paper presenting an analysis of best practices of e-government in six countries in the Western Balkans – Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia. The cases of best practice have been identified through an interactive research process, and analyzed through a combined lens of eGovernment stage-models and core public values. The analysis shows how new digital government applications and innovations are designed and used in new democracies as part of new state building structures. The findings indicate a lack of new institutional arrangements for digital government. Taken together it shows that the development of e-government in the Western Balkans follows a path-dependence of other states, in spite of the opportunities for more innovative and sustainable e-government by continuing the institutional reformation
