Designing a Situational Awareness Information Display: Adopting an Affordance-Based Framework to Amplify User Experience in Environmental Interaction Design

Abstract: User experience remains a crucial consideration when assessing the successfulness of information visualization systems. The theory of affordances provides a robust framework for user experience design. In this article, we demonstrate a design case that employs an affordance-based framework and evaluate the information visualization display design. SolarWheels is an interactive information visualization designed for large display walls in computer network control rooms to help cybersecurity analysts become aware of network status and emerging issues. Given the critical nature of this context, the status and performance of a computer network must be precisely monitored and remedied in real time. In this study, we consider various aspects of affordances in order to amplify the user experience via visualization and interaction design. SolarWheels visualizes the multilayer multidimensional computer network issues with a series of integrated circular visualizations inspired by the metaphor of the solar system. To amplify user interaction and experience, the system provides a three-zone physical interaction that allows multiple users to interact with the system. Users can read details at different levels depending on their distance from the display. An expert evaluation study, based on a four-layer affordance framework, was conducted to assess and improve the interactive visualization design.

Guidelines for cybersecurity visualization design

Abstract: Cyber security visualization designers can benefit from human factors engineering concepts and principles to resolve key human factors challenges in visual interface design. We survey human factors concepts and principles that have been applied in the past decade of human factors research. We highlight these concepts and relate them to cybersecurity visualization design. We provide guidelines to help cybersecurity visualization designers address some human factors challenges in the context of interface design. We use ecological interface design approach to present human factors-based principles of interface design for visualization. Cyber security visualization designers will benefit from human factors engineering concepts and principles to resolve key human factors challenges in visual interface design.

CyberSAVe – Situational Awareness Visualization for Cyber Security of Smart Grid Systems (Demo, Presentation)

Abstract: We offer algorithms and visualization techniques for cyber trust in a Smart Grid system. Cyber trust is evaluated in terms of a mathematical model consisting of availability, detection and false alarm trust values, as well as a model of predictability. We develop a prototype Cyber Situational Awareness Visualization (CyberSAVe) tool to visualize cyber trust. We provide Operational Decision Aids (ODAs) displayed in context with a SCADA management information. We define cyber trust metrics, which are calculated and displayed in real-time in the Metric Assessment System (MAS) of CyberSAVe. We demonstrate the use of trust combined with visualization of trust to detect various types of attacks on the Smart Grid.
