Associação entre obesidade e a ocupação dos tempos livres dos jovens no aprovei...

Alguns dos aspetos menos positivos do desenvolvimento da sociedade atual, refletido entre outros, na forma como os jovens se alimentam e ocupam o seu tempo livre, têm vindo a ser alvo de interesse na comunidade científica bem como na comunidade escolar. Como professores, e lidando com frequência com o aspeto avaliativo dos domínios psico-motor, socio-afetivo e cognitivo destas crianças, interrogamo-nos sobre a ...

Interaction Tasks and Controls for Public Display Applications

Design considerations for application selection and control in multi-user publi...

Urban spaces are increasingly embedded with various types of public digital displays. Many of these displays can be subject to multi-user interactions and support a broad range of applications. A fundamental implication emerging from the interactive nature of those applications is that users should have access to appropriate selection and control techniques that would allow them to drive the way applications a...

Situatedness for global display web apps

Most display systems are making use of static definition for the places in which they are situated. The content shown on these displays is predefined as is the case of television broadcasting. In this paper we present an approach that allows local display managers, e.g., display owners, to instantiate global display web applications on each display basis. We describe an innovative model for content presen...

Mobile applications for open display networks : common design considerations

Mobile devices can be a powerful tool for interaction with public displays, but mobile applications supporting this form of interaction are not yet part of our everyday reality. There are no widely accepted abstractions, standards, or practices that may enable systematic interaction between mobile devices and public displays. We envision public displays to move away from a world of closed display networks to sc...

Evaluation of a programming toolkit for interactive public display applications

Interaction is repeatedly pointed out as a key enabling element towards more engaging and valuable public displays. Still, most digital public displays today do not support any interactive features. We argue that this is mainly due to the lack of efficient and clear abstractions that developers can use to incorporate interactivity into their applications. As a consequence, interaction represents a major overhea...

Key challenges in application and content scheduling for Open Pervasive Display...

Today’s digital signage systems typically show content that has been scheduled well in advance by their respective “owners”, i.e., companies or individuals who paid for and/or operate the public display. However, with the shift to open display networks that can obtain content from many sources and the corresponding advances in interaction and sensing technologies, the scheduling requirements in this domain are ...

Pins and posters : paradigms for content publication on situated displays

Public display systems are still far from being a communication medium that people can appropriate to serve diverse communication goals. Moving towards open displays will require new publication paradigms that can overcome the challenges of meaningful engagement and enable users to fully understand and control the entire publication process. In this paper, we report on the study of two novel and complimentary c...

A practical framework for ethics - the PD-Net approach to supporting ethics com...

Research involving public displays often faces the need to study the effects of a deployment in the wild. While many organizations have institutionalized processes for ensuring ethical compliance of such human subject experiments, these may fail to stimulate sufficient awareness for ethical issues among all project members. Some organizations even require such assessments only for medical research, leaving comp...

Promoting secondary school learners' curiosity towards science through digital ...

This paper contributes to the understanding of how digital public displays can be utilized in schools taking into consideration educational goals. This work is part of a currently on-going research project that aims to promote students' curiosity in science and technology through creative film-making, collaborative editing activities, and content sharing. In order to explore the design space concerning digital ...
