Mobile-assisted language learning [Revised and updated version]
Mobile-assisted language learning (MALL) is the use of smartphones and other mobile technologies in language learning, especially in situations where portability and situated learning offer specific advantages. A key attraction of mobile learning is the ubiquity of mobile phones. Typical applications can support learners in reading, listening, speaking and writing in the target language, either individually or in collaboration with one another. Increasingly, MALL applications relate language learning to a person’s physical context when mobile, primarily to provide access to location-specific language material or to enable learners to capture aspects of language use in situ and share it with others. Mobile learning can be formal or informal, and mobile devices may form a bridge connecting in-class and out-of-class learning. When learning takes place outside the classroom, it is often beyond the reach and control of the teacher. This can be perceived as a threat, but it is also an opportunity to revitalize and rethink current approaches to teaching and learning. Mobile learning appeals to a wide range of people for a variety of reasons. It may exclude some learners but it is often a mechanism for inclusion. It is likely that the next generation of mobile learning will be more ubiquitous, which means that there will be smart systems everywhere for digital learning. Mobile learning is proving its potential to address authentic learner needs at the point at which they arise, and to deliver more flexible models of language learning
QR Code Approach for Examination Process
Using the QR codes is one of the most intriguing ways of digitally connecting consumers to the internet via mobile phones since the mobile phones have become a basic necessity thing of everyone The detection of QR codes, a type of 2D barcode, as described in the literature consists merely in the determination of the boundaries of the symbol region in images obtained with the specific intent of highlighting the symbol .In order to improve the practical application property of the two-dimensional barcode Quick Response (QR) code, we investigate the coding and decoding process of the QR code image. The barcode is a real mechanism for data reads. Data can be stored, embedded and through the scanning device to show. The store of data which being read. In this paper, we present a methodology for creating QR code approach for virtual word examination process by using different techniques like SHA256, encoding, decoding, and Error correction.

An Investigation of the Influence of Intrinsic Motivation on Students’ Intention to Use Mobile Devices in Language Learning
This study examines the relationships among intrinsic motivation, critical variables related to technology adoption, and students’ behavioral intention in Mobile-assisted language learning (MALL). To test the hypothesized model through a path analysis, 169 survey responses were collected from undergraduate students who were foreign language learners of English in a Chinese research university. The results indicated that although intrinsic motivation did not have a direct influence on students’ behavioral intention in MALL, it had a positive influence on students’ behavioral intention through the two intervening variables, perceived usefulness and task technology fit. Perceived ease of use, however, was not associated with students’ behavioral intention directly, nor was it predicted by intrinsic motivation. The findings suggested proper instructional design that is aligned with and supports the language learning task was important to increase students’ behavioral intention to adopt mobile devices for language learning

The Crisis of Language in Contemporary Japan: Reading, Writing, and New Technology
My dissertation is an ethnographically inspired theoretical exploration of the crises of reading and writing in contemporary Japan. Each of the five chapters examines concrete instances of reading and writing practices that have been problematized in recent decades. By calling attention to underlying moral assumptions, established sociocultural protocols, and socio-technological conditions of the everyday, I theorize the concept of embodied reading and writing thresholds. The scope of analysis is partly informed by popular discourse decrying a perceived decline in reading and writing proficiency among Japanese youth. This alleged failing literacy figures as a national crisis under the assumption that the futurity of children's national language proficiency metonymically correlates with the future well being of its national cultural body. In light of heightened interests in the past, present, and future of books, and a series of recent state interventions on the prospect of "national" text culture, it is my argument that ongoing tensions surrounding the changing media landscape and symbolic relations to the world do not merely reflect changes in styles of language, structures of spatiotemporal awareness, or forms of knowledge production. Rather, they indicate profound transformations and apprehensions among the lives mediated and embodied by the very system of signification that has come under scrutiny in the post-Lost Decade Japan (03/1991-01/2002). My dissertation offers an unique point of critical intervention into 1) various forms of tension arising from the overlapping media technologies and polarized population, 2) formations of reading and writing body (embodiment) at an intersection of heterogeneous elements and everyday disciplining, 3) culturally specific conditions and articulations of the effects of "universal" technologies, 4) prospects of "proper" national reading and writing culture, and 5) questions of cultural transformation and transmission. I hope that the diverse set of events explored in respective chapters provide, as a whole, a broader perspective of the institutional and technological background as well as an intimate understanding of culturally specific circumstances in Japan. Insofar as this is an attempt to conduct a nuanced inquiry into the culturally specific configurations and articulations of a global phenomenon, each ethnographic moment is carefully contextualized to reflect Japan specific conditions while avoiding the pitfall of culturalist assumptions. Understanding how an existing system of representation, technological imperatives and sociohistorical predicaments have coalesced to form a unique constellation is the first step in identifying how the practice of reading and writing becomes a site of heated national debate in Japan. Against theories that problematize the de-corporealizing effects of digital technology within reading and writing, I emphasize the material specificity of contemporary reading and writing practices
PhobiAR, an artefact of augmented reality to support the exposure therapy of specific phobias
Dissertação de mestrado integrado em Informatics EngineeringPhobia is a type of anxiety disorder defined by a persistent and excessive fear of an
object or situation. Currently, exposure therapy is the most practiced method to treat
phobias, although it comes with limitations. We can reduce these limitations by combining
Augmented Reality techniques with exposure therapy. Its benefits are a decrease in costs,
versatility of the process, and full control of the procedure by the therapist. As shown in
multiple research, Augmented Reality has obtained interesting results in the therapy of
psychological disorders serving as a foundation for the development of this project. The
recent technological advances in the field also allowed for easier access to Augmented Reality
which is accessible to use even in old smartphones. The goal of this Master’s dissertation
was to develop an artefact in conjunction with psychologists who treat phobic patients, to
create a program to support the therapy of phobias with a gradual exposure system. Their
help was essential to understand the most important features needed for the platform. The
platform was deployed in the informatics department servers, which could be accessed
by everyone that had internet connection. Multiple psychologists were invited to test the
platform by following a user guide created and give their technical feedback in the end. The
results gathered were positive, which proves the viability of this system as an extension to
the current methods by providing comfort and efficiency.A fobia é um tipo de transtorno de ansiedade definido por um medo persistente e excessivo
de um objeto ou situação. Atualmente, o terapia de exposição é o método mais praticado para
tratar fobias, embora com limitações. Estas limitações são reduzidas combinando técnicas de
Realidade Aumentada com a terapia de exposição. Os seus benefícios são uma redução de
custos, versatilidade do processo e controle total do procedimento pelo terapeuta. Como foi
demostrado em várias pesquisas, a Realidade Aumentada obteve resultados interessantes
no tratamento de distúrbios psicológicos, servindo de base para o desenvolvimento deste
projeto. Os recentes avanços tecnológicos no campo permitem também um acesso fácil à
Realidade Aumentada, acessível para uso mesmo em smartphones antigos. Nosso objetivo
é desenvolver um artefato em conjunto com psicólogos que tratam de pacientes fóbicos,
para criar um programa para apoiar o tratamento de fobias com um sistema de exposição
gradual. A ajuda deles foi essencial para entender os recursos que são mais importantes para
a plataforma. A plataforma foi colocada nos servidores do departamento de informática e
podia ser acedida por qualquer pessoa que tivesse conexão à internet. Vários psicólogos
foram convidados a testar a plataforma seguindo um guião criado e dando seu feedback
técnico no final. Os resultados recolhidos foram positivos, o que comprova a viabilidade
deste sistema como uma extensão dos métodos atuais providenciando conforto e eficiência
