Towards Rapid Generation and Visualisation of Large 3D Urban Landscapes for Mobile Device Navigation
In this paper a procedural 3D modelling solution for mobile devices is presented based on scripting algorithms allowing for both the automatic and also semi-automatic creation of photorealistic quality virtual urban content. The combination of aerial images, GIS data, 2D ground maps and terrestrial photographs as input data coupled with a user-friendly customized interface permits the automatic and interactive generation of large-scale, accurate, georeferenced and fully-textured 3D virtual city content, content that can be specially optimized for use with mobile devices but also with navigational tasks in mind. Furthermore, a user-centred mobile virtual reality (VR) visualisation and interaction tool operating on PDAs (Personal Digital Assistants) for pedestrian navigation is also discussed. Via this engine, the import and display of various navigational file formats (2D and 3D) is supported, including a comprehensive front-end user-friendly graphical user interface providing immersive virtual 3D navigation

Mobile Learning Revolution: Implications for Language Pedagogy
Mobile technologies including cell phones and tablets are a pervasive feature of everyday life with potential impact on teaching and learning. âMobile pedagogyâ may seem like a contradiction in terms, since mobile learning often takes place physically beyond the teacher's reach, outside the walls of the classroom. While pedagogy implies careful planning, mobility exposes learners to the unexpected. A thoughtful pedagogical response to this reality involves new conceptualizations of what is to be learned and new activity designs. This approach recognizes that learners may act in more self-determined ways beyond the classroom walls, where online interactions and mobile encounters influence their target language communication needs and interests. The chapter sets out a range of opportunities for out-of-class mobile language learning that give learners an active role and promote communication. It then considers the implications of these developments for language content and curricula and the evolving roles and competences of teachers
Mobile technology capabilities in creative service firms: A resource-based perspective
This paper endeavours to understand the process of mobile technology (MT) employment in creative service firms through the prism of a Resource-based View. In doing this, it utilises the competence framework proposed by Sanchez (2003), according to which firms that operate as an âopen systemâ of resources and capabilities excel in the strategic competition. The case study approach is applied to describe and examine the chosen framework in six firms through in-depth interviewing and analysing secondary sources. With respect to findings, MT resources are deployed in accordance with the strategic logic of a firm. There is a general consensus that MT is non-substitutable but strategically useful. All six firms share a common coordination mechanism in managing MT resources in the form of a relationship management. The role of management is stressed in the form of an account manager who uses clientsâ objectives as means for allocating tasks and resources
Theoretical perspectives on mobile language learning diaries and noticing for learners,teachers and researchers
This paper considers the issue of 'noticing' in second language acquisition, and argues for the potential of handheld devices to: (i) support language learners in noticing and recording noticed features 'on the spot', to help them develop their second language system; (ii) help language teachers better understand the specific difficulties of individuals or those from a particular language background; and (iii) facilitate data collection by applied linguistics researchers, which can be fed back into educational applications for language learning. We consider: theoretical perspectives drawn from the second language acquisition literature, relating these to the practice of writing language learning diaries; and the potential for learner modelling to facilitate recording and prompting noticing in mobile assisted language learning contexts. We then offer guidelines for developers of mobile language learning solutions to support the development of language awareness in learners
Medical Cyber-Physical Systems Development: A Forensics-Driven Approach
The synthesis of technology and the medical industry has partly contributed
to the increasing interest in Medical Cyber-Physical Systems (MCPS). While
these systems provide benefits to patients and professionals, they also
introduce new attack vectors for malicious actors (e.g. financially-and/or
criminally-motivated actors). A successful breach involving a MCPS can impact
patient data and system availability. The complexity and operating requirements
of a MCPS complicates digital investigations. Coupling this information with
the potentially vast amounts of information that a MCPS produces and/or has
access to is generating discussions on, not only, how to compromise these
systems but, more importantly, how to investigate these systems. The paper
proposes the integration of forensics principles and concepts into the design
and development of a MCPS to strengthen an organization's investigative
posture. The framework sets the foundation for future research in the
refinement of specific solutions for MCPS investigations.Comment: This is the pre-print version of a paper presented at the 2nd

Calm before the storm: the challenges of cloud computing in digital forensics
Cloud computing is a rapidly evolving information technology (IT) phenomenon. Rather than procure, deploy and manage a physical IT infrastructure to host their software applications, organizations are increasingly deploying their infrastructure into remote, virtualized environments, often hosted and managed by third parties. This development has significant implications for digital forensic investigators, equipment vendors, law enforcement, as well as corporate compliance and audit departments (among others). Much of digital forensic practice assumes careful control and management of IT assets (particularly data storage) during the conduct of an investigation. This paper summarises the key aspects of cloud computing and analyses how established digital forensic procedures will be invalidated in this new environment. Several new research challenges addressing this changing context are also identified and discussed
Conceptual evidence collection and analysis methodology for Android devices
Android devices continue to grow in popularity and capability meaning the
need for a forensically sound evidence collection methodology for these devices
also increases. This chapter proposes a methodology for evidence collection and
analysis for Android devices that is, as far as practical, device agnostic.
Android devices may contain a significant amount of evidential data that could
be essential to a forensic practitioner in their investigations. However, the
retrieval of this data requires that the practitioner understand and utilize
techniques to analyze information collected from the device. The major
contribution of this research is an in-depth evidence collection and analysis
methodology for forensic practitioners.Comment: in Cloud Security Ecosystem (Syngress, an Imprint of Elsevier), 201
Learning IoT without the "I" - Educational Internet of Things in a Developing Context
To provide better education to children from different socio-economic backgrounds, the Thai Government launched the "One Tablet PC Per Child" (OTPC) policy and distributed 800,000 tablet computers to first grade students across the country in 2012. This initiative is an opportunity to study how mobile learning and Internet of Things (IoT) technology can be designed for students in underprivileged areas of northern Thailand. In this position paper, we present a prototype, called OBSY (Observation Learning System) which targets primary science education. OBSY consists of i) a sensor device, developed with low-cost open source singled-board computer Raspberry Pi, housed in a 3D printed case, ii) a mobile device friendly graphical interface displaying visualisations of the sensor data, iii) a self-contained DIY Wi-Fi network which allows the system to operate in an environment with inadequate ICT infrastructure
Pedagogic approaches to using technology for learning: literature review
This literature review is intended to address and support teaching qualifications and CPD through identifying new and emerging pedagogies; "determining what constitutes effective use of technology in teaching and learning; looking at new developments in teacher training qualifications to ensure that they are at the cutting edge of learning theory and classroom practice and making suggestions as to how teachers can continually update their skills." - Page 4
