The next generation of social media will utilize advanced visualization methods for real time co-experiencing of real environments. Our cases promote the use of virtual and augmented reality, visualizing people, vehicles and content on mobile devices and immersively with head mounted displays on desktops. Our demonstrations include Android tablets and Oculus Rift/HTC VIVE displays.

Measuring the security level of an information system to acquire reliable perception of its state requires the use of various different security metrics that can provide extensive security evidence of the system. Visualization can then be used to facilitate the management of the security metrics and measurements and to enhance understanding on their relationships. This paper introduces a tool for modeling and monitoring the security state of a system and focuses on the visualization aspects of the tool. The security metrics of a system are organized hierarchically in the tool, so that more general and conceptual security metrics on the higher levels are connected to detailed, low-level measurements. The tool helps bring meaningfulness to the security metrics and helps the user be more aware of the security state of the system during runtime use of the tool. By having organized security evidence from high-level objectives to low-level measurements the user is able to act on the security incidents more proficiently.

Traditional risk management produces a rather static listing of weaknesses, probabilities and mitigations. Large share of cyber security risks realize through computer networks. These attacks or attack attempts produce events that are detected by various monitoring techniques such as Intrusion Detection Systems (IDS). Often the link between detecting these potentially dangerous real-time events and risk management process is lacking, or completely missing. This paper presents means for transferring and visualizing the network events in the risk management instantly with a tool called Metrics Visualization System (MVS). The tool is used to dynamically visualize network security events of a Terrestrial Trunked Radio (TETRA) network running in Software Defined Networking (SDN) context as a case study. Visualizations are presented with a treelike graph, that gives a quick easily understandable overview of the cyber security situation. This paper also discusses what network security events are monitored and how they affect the more general risk levels. The major benefit of this approach is that the risk analyst is able to map the designed risk tree/security metrics into actual real-time events and view the system's security posture with the help of a runtime visualization view.

Web services and applications are an increasingly pervasive fixture of modern life and business. This paper reports on a Web-based crowdsourced subjective assessment campaign in which we studied the effects of network performance and design aspects of manipulated Web sites on the perceived performance, perceived ease-of-use, visual appeal, as well as on the overall Quality of Experience of users browsing a given Web site. We consider the simultaneous impact of multiple factors on different dimensions of QoE, as well as their interplay, with a focus on the interactions between page/element loading times and Web site visual appeal and ease-of-use. Key results have shown the following: page loading times and visual appeal have a significant effect on overall user QoE ; both higher perceived aesthetics and higher perceived ease-of-use result in an increased user tolerance to delay ; and overall QoE is strongly correlated with perceived aesthetics, perceived ease-of-use, and perceived network performance.
