These evolving operational contexts demand a full spectrum dynamic response of ‘data-to-decision’ from IF systems. Traditional information extraction and fusion levels typically address the “data” end of the spectrum, while recent advancement in Machine Learning (ML) and Artificial Intelligence (AI) approaches are being used for the “decisions” end of the spectrum. However, the IF system behavior emerges from the various complex interactions that take place between different fusion levels (including human interaction), the operational context, and the employed AI/ML techniques. In this paper, we explore this emergent behavior of the IF system and argue that holistic system design and evaluation techniques, as offered by System Engineering (SE), provide means to recognize and characterize this emergent behavior. Furthermore, we describe the research challenges for future IF systems that will enable managing emergence by leveraging SE, while exploiting the context-aware information fusion aided by the advancements in AI/ML.

This study demonstrates that properly designed augmented reality interfaces can significantly aid human operators in the task of land based tele-robotic navigation. Participants in this study were assigned to one of three experimental conditions (control, sonification interface, visual interface). All participants were trained in tele-robotic landmine detection and navigation, the groups performed these tasks first with augmentation (session one) and then without (session two/transfer task). The results show that participants in the sonification interface group outperformed the visual interface and control group in terms of primary task sensitivity, the number of sectors cover and the number of sectors repeated. The results further indicated that a well designed AR navigation interface could serve as an effective training tool.

Chapters are contributed by the foremost international experts, spanning numerous developments and applications. The book highlights high- and low-level information fusion problems, performance evaluation under highly demanding conditions, and design principles. A particular focus is placed on approaches that integrate research from different communities, emphasizing the benefit of combining different techniques to overcome the limitations of a single perspective. Features: introduces the terminology and core elements in information fusion and context; presents key themes for context-enhanced information fusion; discusses design issues in developing context-aware fusion systems; provides mathematical grounds for modeling the contextual influences in representative fusion problems; describes the fusion of hard and soft data; reviews a diverse range of applications.
