    Mobiles and wearables: owner biometrics and authentication

    Get PDF
    We discuss the design and development of HCI models for authentication based on gait and gesture that can be supported by mobile and wearable equipment. The paper proposes to use such biometric behavioral traits for partially transparent and continuous authentication by means of behavioral patterns. © 2016 Copyright held by the owner/author(s)

    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.

    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

    PhobiAR, an artefact of augmented reality to support the exposure therapy of specific phobias

    Get PDF
    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
