Evaluation of MixedReality Systems This chapter focuses on the usefulness of a mixedreality system that is complementary to the usability ofthe system As part of an iterative usercentred design approach, this chapter highlights the value of qualitative methods in natural setting for evaluating the usefulness of a mixedreality system Two case studies of mixedreality systems and their qualitative experimental... the most challenging aspects of interactive systems is the integration ofthe physical and digital aspects of interaction in a smooth and usable way The design challenge of such mixedreality (MR) systems lies in the fluid and harmonious fusion ofthe physical and digital worlds Examples of MR systems include tangible user interfaces, augmented reality, augmented virtuality and embodied interfaces The. .. used by the user to perform her/his task or the object that is the focus ofthe task To model mixed interaction, we enrich the instrumental interaction model [3] with the notion of interaction modality (d, l) [24] We study the two types ofmixed objects, namely mixed tool and mixed task object, involved in the interaction in light of a definition of an interaction modality [24] as the coupling of a physical... highlight this variety The last part ofthe anthology is dedicated to applications ofmixedreality 1.2 MixedRealityEngineering In this very dynamic research and industrial context, the goal of this anthology is to go one step ahead to gain understanding of this challenging domain The book covers topics on mixedrealityengineering by addressing the design and development of such systems: it includes... in the system is like an in the real world.” To assess the noun metaphor based on the modeling ofmixed interaction, we study how the physical properties reflect the task performed with themixed object For example in Fig 2.7 (dotted dark gray), the physical properties ofthe eraser reflect the task: erasing The Dome Phicon belongs to the same category, as opposed to the tokens of NavRNA, the cubes . representational options of mixed systems. 1.2.3 Application of Mixed Reality The final section consists of a set of detailed case studies that highlight the appli- cation of mixed reality in a number of fields,. The diversity of terms highlights the ever growing interest in MR systems and the very dynamic and challenging domain they define. 1.1.1 Variety of Mixed Reality Systems The growing interest of. Design of Mixed Reality Systems. Like the approach described in Chapter 10, the software engineering process model presented here proposes that mixed reality systems are developed via the progressive
