    MiRA - mixed reality agents
    In recent years, an increasing number of Mixed Reality (MR) applications have been developed using agent technology—both for the underlying software and as an interface metaphor. However, no unifying field or theory currently exists that can act as a common frame of reference for these varied works. As a result, much duplication of research is evidenced in the literature. This paper seeks to fill this important gap by outlining ‘‘for the first time’’ a formal field of research that has hitherto gone unacknowledged, namely the field of Mixed Reality Agents (MiRAs), which are defined as agents embodied in a Mixed Reality environment. Based on this definition, a taxonomy is offered that classifies MiRAs along three axes: agency, based on the weak and strong notions outlined by Wooldridge and Jennings (1995); corporeal presence, which describes the degree of virtual or physical representation (body) of a MiRA; and interactive capacity, which characterises its ability to sense and act on the virtual and physical environment. Furthermore, this paper offers the first comprehensive survey of the state-of-the-art of MiRA research and places each project within the proposed taxonomy. Finally, common trends and future directions for MiRA research are discussed. By defining Mixed Reality Agents as a formal field, establishing a common taxonomy, and retrospectively placing existing MiRA projects within it, future researchers can effectively position their research within this landscape, thereby avoiding duplication and fostering reuse and interoperability.

    NeXus: Behavioural Realism in Mixed Reality Scenarios through Virtual Sensing
    This paper aims to demonstrate how behavioural realism can be achieved by situating intentional agents within an Augmented Reality (AR) framework. We contest that imbuing agents with the ability to virtually sense the world within which they are situated produces a heightened sense of behavioural realism. We introduce the reader to NeXuS, a framework for the development of AR applications that depends upon these concepts to create a rich interactive environment whereby traditional boundaries between the virtual and physical domain may be overcome.

    NeXuS: delivering behavioural realism through intentional agents
    This paper explores the challenge of delivering Behavioural Realism to embedded avatars. An agent based approach is adopted and demonstrated within a Mixed Reality (MR) environment. The realism of an avatar is driven by the state of the intentional agent that underpins its behaviour. The traditional disconnect often found with avatars that exhibit shallow levels of behavioural realism is no longer evident.

    Facilitating ubiquitous interaction using intelligent agents
    Facilitating intuitive interaction is a prerequisite for the ubiquitous computing paradigm in all its manifestations. How to achieve such interaction in practice remains an open question. Such interfaces must be perceived as being intuitive across a variety of contexts, including those of the hosting devices. Indeed, the heterogeneity of the device population raises significant challenges. While individual devices and the interaction modalities supported by, each satisfy the requirements of individual domains, integrating diverse devices such that the user experiences is perceived as consistent and intuitive is problematic. This chapter discusses and illustrates how intelligent agents may be harnessed for integrating a range of diverse interface and interaction modalities such that the ubiquitous user interface concept may be validated.
