Este trabalho buscou identificar como a mineração de dados (MD) e algoritmos de filtros bolha são utilizados a favor de notícias falsas e maliciosas, denominadas fake news. Além de traçar uma ligação entre a MD e a propagação de notícias falsas no âmbito das mídias sociais, buscou-se identificar mecanismos de prevenção e proteção. Para este fim, fo...

O uso de sistemas computacionais para cuidados com a saúde deidosos é cada vez mais comum. No campo da educação, no entanto,as investigações enfocam mais em questões técnicas de desenvolvimento ou em adaptação de tecnologias, e não no processo deensino-aprendizagem e aplicabilidade do uso de dispositivos móveis.Este trabalho buscou estimular, monit...

BACKGROUND Health professionals initiating mHealth interventions may choose to adapt apps designed for other activities (eg, peer-to-peer communication) or to employ purpose-build apps specialized on the required intervention, or to exploit apps based on methods such as the Experience Sampling Method (ESM). An alternative approach would be professi...

Background Health professionals initiating mobile health (mHealth) interventions may choose to adapt apps designed for other activities (eg, peer-to-peer communication) or to employ purpose-built apps specialized in the required intervention, or to exploit apps based on methods such as the experience sampling method (ESM).

Nowadays, using mobile and communication technologies helps the elderly population to stay active by promoting social interactions and independence in many daily tasks, such as paying their bills. Therefore, we can identify many efforts for the digital inclusion of the elderly. However, just offering access to the new technologies, such as touch-ba...

Contar histórias, uma atividade intrínseca a grupos de indivíduos, foi sempre da maior importância para a evolução da humanidade. Em comunidades, é comum que idosos, mais experientes, se engajem nessa atividade. Na atualidade inúmeras tecnologias permitem a produção e o compartilhamento de conteúdo de modo geral, e de narrativas de modo particular....

A aprendizagem ao longo de toda a vida é um novo paradigma e um princípio organizador para os sistemas de educação e aprendizagem frente ao século XXI proposto pela UNESCO. Já o letramento digital envolve outras novas competências e podem auxiliar no uso das Tecnologias da Informação e Comunicação para o benefício na vida pessoal e coletiva. Propõe...

The use of video as instructional content has become popular in web-based learning environments. Even though video is an established media, the way users access and interact with video vary among systems and may influence how students experience and engage on courses. Previous studies have focused on analysing the effects on students' engagement, l...

As mobile devices become accessible to a large part of the population, they can be used by professionals and researchers to conduct remote personalized interventions and data collection. However, developing mobile applications is not a trivial task as it requires a wide variety of programming skills. For professionals and researchers from areas suc...

BACKGROUND Being socially connected is related to well-being in older age. The use of social media helps people to stay connected despite physical proximity. However, some older people are resistant to mainstream social networking technology which they see as shallow compared to face-to-face contact. OBJECTIVE In this paper, we report the design a...

Background Being socially connected is related to well-being, and one way of avoiding social isolation is to deepen existing relationships. Even though existing relationships can be reinforced by regular and meaningful communication, state-of-the-art communication technologies alone do not increase the quality of social connections. Thus, there is...

Collecting data and carrying out interventions with different populations of interest is a common procedure in the professional life of specialists such as psychologists, gerontologists, etc. The ESPIM is a platform designed to enable the authoring of intervention programs by specialists of different domains. The programs authoring is done via a We...

Due to the popularity of smartphones and their built-in sensors, Context-Aware Mobile (CAM) applications are on the rise. Some libraries and APIs help developers to create CAM applications, such as the Google Awareness API. However, the initial configuration, the write of context-aware rules, and code readability persist being complex tasks, specia...

Mobile computing can be a facilitator for collecting data due to the fact that users carry their smartphones almost everywhere and all the time and because they can collect a wide range of data -- textual, audiovisual and data collected automatically by sensors. Considering this opportunity, we developed the ESPIM (Experience Sampling and Programme...

A particularly challenging situation in amateur multimedia authoring is ad-hoc collaborative capture, i.e., a process that, having no pre-production phase, demands live coordination between multiple authors. Important problems to realize such scenarios include proper synchronization of media elements by multiple devices, and which information to in...

The Experience Sampling Method (ESM) has been proposed as a method for collecting data about people's experiences in their everyday and natural environments. ESM-based systems offer limited authoring for interactive documents designed to collect text-based responses offered as answers to text-based questions, and integrated with the non-intrusive d...

Despite recent results allowing collaborative video capture using mobile devices, there is a gap in promoting collaborative capture of media other than video. In this paper we report our collaborative model supporting amateur and opportunistic collaborative recording of multiple media using mobile devices. We present a case study carried out in the...

Mobile devices such as smartphones and tablets have the potential to enhance the connectivity of older adults with their family and friends. However, many older adults face difficulties when introduced to the devices and, as a result, they may end up being excluded from circles that require them to be educated in the corresponding technology. In su...

The present course aims to introduce the attendants to the Experience Sampling and Programmed Intervention Method (ESPIM). This method combines selected procedures from the field of Psychology, such as Individualized Programmed Teaching and Experience Sampling Method (ESM), and the advantages promoted by ubiquitous computing. Our goal is to enhance...

In this work, we present a case study in which participants used a mobile application for collaborative record presentations. We developed an application for Android-enabled devices to investigate the usability and design requirements of a mobile and collaborative capture system. Our main concern is to facilitate collaboration and create an enhance...

Annotations enable us to highlight key points or add information to content presented, for instance, on paper or digital media. Even though smartphones and tablets facilitate video capturing, currently only few applications allow limited video annotations using the mobile device itself. Given that video annotations can assist many tasks that depend...

The tourism sector in Brazil has grown considerably in recent years. Despite this growth, the sector still presents several problems such as the lack of information in Portuguese and in other languages for Brazilian and foreign tourists. The absence of information about tourist sites and ordinary services also affects individuals when settling in a...

Modern mobile devices are natural multimedia devices that enable one to access, manage and transmit multiple types of media such as video, photo, audio and maps. Video playing on these devices is becoming part of everyday life for many users. Aiming to enhance the video playback activity, we built a tool that allows temporal video annotation on mob...

The user interaction with mobile devices has dramatically improved over the last years. Increasingly we rely on smartphones and tablets for a wider range of tasks. Modern mobile devices enable users to access, manage and transmit multiple types of media in an easy, convenient and portable way. In this context, the playback of videos on mobile devic...

The growing ease of capturing and playing back videos using mobile devices demands the investigation of alternatives for improving the user experience, for instance by taking advantage of the expanding culture of end-user content generation. Advances in terms of end-user media capture and media combination aim at enriching and facilitating the auth...
