Modeling wireless sensor networks using a collaborative graph-based model

Publication . Rodríguez Peralta, Laura M.; Brito, Lina M. Pestana Leão de; Hernández, Eduardo Ismael

: In several application scenarios, like the case of structural monitoring, it is important to model and represent the Wireless Sensor Networks (WSN) to be deployed. To model the components and properties of entire WSN types of collaboration in WSNs, we have created the Collaborative Wireless Sensor Networks (CWSN) model. This model also models the different types of collaboration that occur in a WSN. Our main goal is to provide a theoretical mathematical foundation that can model and analyze WSNs. Our approach is based on graph theory and propositional logic. The main contribution of this paper is applying the CWSN model to describe and represent a WSN. The use of the CWSN model brings several advantages, such as enabling the graphical representation of the state of the network and of several important properties: 1) the network topology; 2) the transmission between nodes considering a multi-hop communication; 3) the transmission hierarchy; 4) the evolution of the networks through a succession of graphs; and so on.

Evaluation of yasmine’s adventures: exploring the socio-cultural potential of location aware multimedia stories

Publication . Dionisio, Mara; Barreto, Mary; Nisi, Valentina; Nunes, Nuno; Hanna, Julian; Herlo, Bianca; Schubert, Jennifer

This paper describes Yasmine’s Adventures, a location aware multi‐ media story designed as a location based service for a museum. Yasmine’s Adventures follows a young local girl (Yasmine) through a series of short animated adventures, tailored specifically to engage visitors in exploring the rela‐ tively neglected streets of the area in which the museum is situated. Yasmine’s perceptions of the landmarks, identified by community members themselves, reflect the real concerns of the community. Results from the evaluation of the user’s experience suggest location connection and perception changes when loca‐ tive media narratives include learning, understanding and discovery elements.

Second look: combining wearable computing and crowdsourcing to support creative writing

Publication . Campos, Pedro; Gonçalves, Frederica; Martins, Michael; Campos, Miguel; Freitas, Paulo

We present “Second Look”, a platform for helping people, in particular creative writers, to overcome writer’s block. This ubiquitous platform combines augmented reality (Google Glass and AR markers), ubiquitous computing (mobile phones), and crowdsourcing in order to improve the creativity, focus and performance of creative writers. A primary challenge in developing and evaluating creativity support tools is that we are not able to detect when a person is being creative. Our approach improves current ones by exploring the “in-the moment” creativity and supporting it with adaptive ubiquitous technologies that try to keep people in a creative experience peak for a longer period of time.

Second look: combining interactive surfaces with wearable computing to support creative writing

Publication . Campos, Pedro; Gonçalves, Frederica; Martins, Michael; Campos, Miguel; Freitas, Paulo

We present "Second Look", a platform of interactive surfaces and wearable computing for helping people, in particular creative writers, to overcome writer's block. The novelty of our systems stems from the addition of wearable devices (Google Glass) and crowdsourcing to improve creative writing on tablets and phones. A primary challenge in developing and evaluating creativity support tools is that we are not able to detect when a person is being creative. Our approach improves current ones by exploring the "in-the-moment" creativity and supporting it with adaptive ubiquitous technologies that try to keep people in a creative experience peak for a longer period of time.

Citizen X: designing for holistic community engagement

Publication . Ashby, Simone; Hanna, Julian; Oakley, Ian; Vieira, Tatiana; Abreu, Filipe; Campos, Pedro

Crowdsourcing in urban environments, geospatial annotation, social curation, and engaging citizens through social media applications and community-aware, place-based computing systems are at the forefront of pervasive urban technologies aimed at improving satisfaction, strengthening communities, and empowering citizens as stakeholders. This paper reports on the user-centered design of a holistic community engagement platform that combines the above aims and uncovers insights from both sides of the citizen-government divide for a people's GIS for enhancing urban livability.
