Mobile Online Gaming via Resource Sharing

Mobile gaming presents a number of main issues which remain open. These are concerned mainly with connectivity, computational capacities, memory and battery constraints. In this paper, we discuss the design of a fully distributed approach for the support of mobile Multiplayer Online Games (MOGs). In mobile environments, several features might be exploited to enable resource sharing among multiple devices / game consoles owned by different mobile users. We show the advantages of trading computing / networking facilities among mobile players. This operation mode opens a wide number of interesting sharing scenarios, thus promoting the deployment of novel mobile online games. In particular, once mobile nodes make their resource available for the community, it becomes possible to distribute the software modules that compose the game engine. This allows to distribute the workload for the game advancement management. We claim that resource sharing is in unison with the idea of ludic activity that is behind MOGs. Hence, such schemes can be profitably employed in these contexts.Comment: Proceedings of 3nd ICST/CREATE-NET Workshop on DIstributed SImulation and Online gaming (DISIO 2012).

Exploring heritage through time and space : Supporting community reflection on the highland clearances

On the two hundredth anniversary of the Kildonan clearances, when people were forcibly removed from their homes, the Timespan Heritage centre has created a program of community centred work aimed at challenging pre conceptions and encouraging reflection on this important historical process. This paper explores the innovative ways in which virtual world technology has facilitated community engagement, enhanced visualisation and encouraged reflection as part of this program. An installation where users navigate through a reconstruction of pre clearance Caen township is controlled through natural gestures and presented on a 300 inch six megapixel screen. This environment allows users to experience the past in new ways. The platform has value as an effective way for an educator, artist or hobbyist to create large scale virtual environments using off the shelf hardware and open source software. The result is an exhibit that also serves as a platform for experimentation into innovative ways of community co-creation and co-curation.Postprin

The PO-VE Framework : Understanding the Relationships Between Player Objects and Virtual Environments in Digital Games

Based on a qualitative analysis of 99 different digital games, this study develops a framework for understanding the functionality and relationships between player objects and virtual environments, explored in what has been named the PO-VE framework. The PO-VE framework encompasses a general theory, a dedicated terminology, and an analysis model. A virtual environment is a navigable geometry and a computational, relational model that represents the relative positions and functions of objects within it. Based on a relational and functional approach, objects are conceived of as integrated in the virtual environment by being spatially and functionally related to other objects within it, thus emphasising the virtual environment’s relational system-structure. Within the virtual environment, player objects constitute the player’s point of control. As integrated and movable objects, they consist of attributes (properties such as health, speed, and size) and affordances (possible actions such as running, shooting, and jumping). In most cases, player objects are dynamic (i.e., their attributes and affordances are altered over time); they can not only move along a single axis, but also be used for navigating the virtual environment along multiple axes; and they have some sort of visual presentation, which varies according to the specific visual framing of the player object and the virtual environment. The PO-VE framework results from an analysis and iterative coding process of 99 digital games. The games were chosen using a purposive sampling method guided by a pre-conceptualisation of what constitutes an avatar-based game (the initial focus of the study), popular game examples from game studies literature, and certain diversity labels: year of publication, platform, and country of origin. The PO-VE framework thus results from observational data iteratively translated into codes from games published between 1978 and 2018, across 32 different platforms, developed in 17 different countries. The iterative data collection and coding process, which resembled to some extent that of grounded theory, was finally conceptualised into the PO-VE framework, consisting of a general theory of virtual environments as relational systems, a terminology of player objects in virtual environments, and an analysis model that consists of seven categories related to different aspects of PO-VE relations. To illustrate the applicability of the PO-VE model, two levels of application were employed. The first was a broad analysis of the 78 of the 99 games in the sample that meet the player object definition, which reveals general trends and patterns according to types, genres, and production year of games. The second were close readings of ten chosen games from the sample: Space Attack, Altered Beast, Passage, Hotline Miami, Subway Surfers, ZombiU, LEGO Marvel Super Heroes, Papers, Please, The Witcher 3: Wild Hunt, and Reigns: Her Majesty, that each illustrate the depth of the PO-VE framework, while also clarifying some of the limitations of the framework, including how and why some games, such as Papers, Please and Reigns: Her Majesty, cannot be analysed using the PO-VE framework. The relational foundation of the PO-VE model offers a unique and descriptive approach to analytical game studies that utilises a functional understanding of the digital object. This enables a focus on the environment as a relational system and on integration within it, rather than, for example, on rules, goals, or player experiences. Utilising an OOA/D inspired terminology in the analytical framework is a step towards bridging the gap between humanities-based, theoretical game studies, more technical game studies, and game development. This study is thus a contribution to the most fundamental level of any research endeavour: attempting to map out (parts of) the research object and develop a language that facilitates closer inspection and ultimately a better understanding of digital games and virtual environments.Doktorgradsavhandlin

Exploring Oculus Rift: A Historical Analysis of the ‘Virtual Reality’ Paradigm

This paper will first provide background information about Virtual Reality in order to better analyze its development throughout history and into the future. Next, this essay begins an in-depth historical analysis of how virtual reality has developed prior to 1970, a pivotal year in Virtual Reality history, followed by an exploration of how this development paradigm shifted between the 1970\u27s and the turn of the century. The historical analysis of virtual reality is concluded by covering the modern period from 2000-present. Finally, this paper examines the layout of the virtual reality field in respect to he history and innovations presented

PROJECT ÉVORA 3D: RESEARCH, METHODOLOGY, RECONSTRUCTION AND VISUALIZATION

The Évora 3D project was born from the collaboration between the Municipality and the University of Évora, through the two research centres of CIDEHUS1 and CHAIA2, with the objective of completing a virtual reconstruction of the city in a longtime frame. In the national and international context, the use of new technologies has led to the diversification of this type of proposal, both at the urban level and in the reconstruction of concrete spaces. The application of this same model to Évora, contemplating several chronological layers, seems to impose itself in a city that, in the medieval and modern periods, was one of the most important of the kingdom, as Court city, and that today is classified as World Heritage Site

A framework for P2P application development

Although Peer-to-Peer (P2P) computing has become increasingly popular over recent years, there still exist only a very small number of application domains that have exploited it on a large scale. This can be attributed to a number of reasons including the rapid evolution of P2P technologies, coupled with their often-complex nature. This paper describes an implemented abstraction framework that seeks to aid developers in building P2P applications. A selection of example P2P applications that have been developed using this framework are also presented

Discrete event simulation and virtual reality use in industry: new opportunities and future trends

This paper reviews the area of combined discrete event simulation (DES) and virtual reality (VR) use within industry. While establishing a state of the art for progress in this area, this paper makes the case for VR DES as the vehicle of choice for complex data analysis through interactive simulation models, highlighting both its advantages and current limitations. This paper reviews active research topics such as VR and DES real-time integration, communication protocols, system design considerations, model validation, and applications of VR and DES. While summarizing future research directions for this technology combination, the case is made for smart factory adoption of VR DES as a new platform for scenario testing and decision making. It is put that in order for VR DES to fully meet the visualization requirements of both Industry 4.0 and Industrial Internet visions of digital manufacturing, further research is required in the areas of lower latency image processing, DES delivery as a service, gesture recognition for VR DES interaction, and linkage of DES to real-time data streams and Big Data sets

A sound idea: An investigation into accessible video game design for the deaf and hard of hearing

A widely accepted, and incorrect, assumption towards hearing accessibility in video games is that deaf and hard of hearing (DHH) users are those who encounter the least barriers and are generally well catered for. Rapid advancement in video game technology has seen video game sound evolve from simple blips generated by internal circuitry to fully realised digital audio used to convey critical information. To accommodate the DHH, this information needs to be conveyed in an alternative manner. However, evidence suggests existing accessible design solutions for the DHH lack specificity and are insufficient. Thus, the inability to hear, or hear well, has historically resulted in DHH users left with impeded experience and gameplay. This thesis describes an investigation to address the primary research question: How might accessible video game design practices be facilitated to better accommodate the deaf and hard of hearing? To examine this question, an action research method as part of a transformative mixed methods methodology was used. Data collection procedures included critical analysis of literature, observations, and a cross-sectional self-administered survey for triangulation. The critical analysis of literature exposed issues relating to accessible video game design, particularly in relation to the identification of solutions and technical implementation. Further, issues related to the classification of video game software were identified. This posed potential problems with identification of game design methods and led to the development of a new video game classification model. The new model informed an analysis on the methods used for the design of video games, and results were visually represented and mapped to the different approaches to accessible design. Subsequent analysis determined that a game assessment framework is a suitable approach to facilitating accessible design. Further investigation identified visual feedback as the most suitable form of complementary feedback to game audio. This led to the development of a new model to classify visual feedback elements used in video games, and identification of audio feedback categories based on diegetic film theory. Through triangulation of results, a new game feedback model (GFM) was developed. The GFM was used for observational experimentation to identify and classify individual visual feedback elements used in video games. Each element was analysed and mapped to categories of game sound. The resulting model, with populated data, was used to determine what visual feedback elements may be used to complement specific categories of critical game audio. A survey was subsequently used for triangulation, and resulted in amendments to the final model. Through iterative development, and interpretation of findings, the research culminated in the development of a game assessment framework. The three-step framework aids in the classification of game sounds; assesses the impact of those game sounds; and provides recommendations for complementary visual feedback elements for sounds identified as having an adverse impact on user experience and gameplay if they were to be removed. The framework is innovative and has the potential to provide practical guidance for developers of video games. In addition, this research provides the foundation for future research, with the potential to influence accessible game design for the DHH
