This Editorial lead article for the Journal of Location Based Services surveys this complex and multi-disciplinary field and identifies the key research issues. Although this field has produced early commercial disappointments, the inevitability that pervasive location-aware services on mobile devices will emerge means that much research is needed to inform these developments. The article reviews firstly: the science and technology of positioning, geographic information science, mobile cartography, spatial cognition and interfaces, information science, ubiquitous computing; and secondly the business, content and legal, social and ethics aspects, before synthesising the key issues for this new field.

“…In a common structure, users involve different messaging through middleware modules because of processing on different servers; therefore, these servers need to be installed on the same local network to achieve an acceptable response time; however, modern structures will facilitate the process [104]. The improvement in middleware helps support real-time capability for video streaming [105]. The improvement in middleware helps implement interactive middleware that supports media services [108].…”

A Review on Mixed Reality: Current Trends, Challenges and Prospects

Currently, new technologies have enabled the design of smart applications that are used as decision-making tools in the problems of daily life. The key issue in designing such an application is the increasing level of user interaction. Mixed reality (MR) is an emerging technology that deals with maximum user interaction in the real world compared to other similar technologies. Developing an MR application is complicated, and depends on the different components that have been addressed in previous literature. In addition to the extraction of such components, a comprehensive study that presents a generic framework comprising all components required to develop MR applications needs to be performed. This review studies intensive research to obtain a comprehensive framework for MR applications. The suggested framework comprises five layers: the first layer considers system components; the second and third layers focus on architectural issues for component integration; the fourth layer is the application layer that executes the architecture; and the fifth layer is the user interface layer that enables user interaction. The merits of this study are as follows: this review can act as a proper resource for MR basic concepts, and it introduces MR development steps and analytical models, a simulation toolkit, system types, and architecture types, in addition to practical issues for stakeholders such as considering MR different domains.

“…The ubiquitous computing has environmental problems such as wireless channel fading and mobility. As these problems have possibilities to affect the performance of a network and application, it is often proposed that quality-ofservice (QoS) be handled at the ubiquitous system software level (Tokunaga et al, 2004).…”

One of the main problem with the evaluation of ubiquitous computing (UC) is that we do not have standards guidelines, or metrics, even though there have been many researches on the individual technical aspects of ubiquitous systems. UC systems differ from standard applications in many ways. Therefore, it is very hard to apply the current working standards or metrics to the evaluation of UC system, which leads us to develop a desirable way to deal with this. This paper suggests the evaluation issues of service and system software to provide ubiquitous computing. Also, we investigate how equally the evaluation scopes we have suggested and the quality characteristics could be matched with the current technological feasibility of the ubiquitous computing systems, so we can see what benefits and the deficiencies of the proposed evaluation scopes would be. Two case studies are considered and these can be seen as the most-likely applications in the current ubiquitous computing environment.
