This paper suggested a conceptual model of user engagement for mobile based augmented reality (AR) games. Literature revealed the importance of user engagement for defining a successful technology application such as game. However, user engagement in particular is still not clearly studied for the mobile augmented reality games area. This paper critically reviewed the relations of user engagement elements in the mobile augmented reality game and guidelines that related to engagement for such type of games. It then recommended eight attributes of user engagement conceptual model for mobile based augmented reality games that can be used by game designer to design engaging mobile AR games for the industry and future AR engagement research.

Natural sites, monuments and historical artefacts are Cultural Heritage that must be properly managed to ensure their safeguard. Institutions and corporate body devoted to the Cultural Heritage management have the essential task of supervising them paying particular attention to their conservation, dissemination and fruition. In this regards, digital technologies through ICT (Information and Communication Technologies) and New Media represent useful tools which have to be used in suitable way. In this context, this contribution shares the methodology adopted for the case study of Serralunga d'Alba castle. In particular, the research project shows the process used for getting the digital model of the castle through HBIM (Historic Building Information Modeling) methodology and the development of a VR (Virtual Reality) model tour. The final project obtained is the result of a methodological approach that aimed to optimize time, costs and efforts.

Various campaigns such as 'Save the Earth', 'Earth Hour', and 'Reduce, Reuse, Recycle' are held to create environmental awareness among the general public. The effort is seen endlessly using any means of presentation and communication medium in order to ensure the intended message reach its audience. Meanwhile, the availability of mobile devices and the advent of natural user interfaces have simplified the interaction in games so that it is intuitive for vast audience at different abilities. Hence, this would possibly provide wider audience an engaging experience while playing games and at the same time absorbing the intended message. This article describes the process of designing and developing a gogreen tridimensional (3D) game on a mobile platform. It also discusses educational benefits of games and how the concept of environmental awareness is integrated into the game play in order to educate the general public especially the young ones about their social roles. Initial results on performance assessment reveal that the functionality of interactive elements in the game is excellent and young ones did not have difficulties in playing the game. Future work will focus on how 3D mobile games facilitate informal learning process such as inculcating environmental awareness to the general public.

In this paper, the author addresses the process of achieving visual effects aesthetics with the new extended reality technology that is escalating in the creative media and film industry to execute virtual production. It draws importance of the technical and creative decisions in the very early stage of production known as previsualization to real time in camera visual effects for completion and thus shortening and advancing the process of traditional production. The author signifies three major aspects of virtual production here as part of the objectives which are the XR system, LED screen and real time in-camera visual effects creation.
