- Tag clouds for situated interaction and place profilingPublication . José, Rui; Silva, Bruno; Ribeiro, Fernando ReinaldoTag clouds have become very popular as visual representations of the main topics in document sets or as navigation tools that can provide quick access to resources related with specific topics. However, their ability to represent the information environment associated with any meaningful reality in a way that is collectively visible, actionable and easily understood may also be very relevant, even when the reality being represented is no longer a set of documents or resources, but a stream of interactions occurring within a particular ubiquitous computing environment. In this paper, we explore the use of tag clouds within the context of situated displays and services. We hypothesise that such tag clouds may have a role as dynamic representations of place and also as interaction controls, supporting the same comprehension and navigation functions of classical tag clouds. We describe two case studies in which this concept of situated tag cloud has been experimented in real-world settings. The case studies demonstrate two different applications of the tag cloud concept as the basis for place description and situated interaction. The results obtained from the case studies suggest that situated tag clouds can indeed provide valuable representations of place and situations and can also support simple interaction models, allowing people to reason about the system behaviour and how it is being influenced by new interactions.
- The potential of narrative devices in a video promoting the use of an ambarscience didactic toy in classroomsPublication . Brandão, Daniel; Silva, Bruno; Martins, Nuno; Raposo, Daniel; Neves, João Vasco; Silva, José Gago daThis research aimed to study and develop an advertising video to promote the placement of an ambarscience didactic toy in the Primary School classroom context, as complement to the teaching process, as this is something, according to our study, unprecedented in this type of toys. We aimed to understand the relevance of using nonlinear narrative structure in this type of videos and how the used of flashback and flashforward narrative devices would help in enlightening the learning potential of the toy. For Albino (Albino 2013) babies since birth are highly predisposed to learn and their brain naturally absorbs all the information of new life, this is not optional, it is a human condition. According to the same author, since children are born they are constantly absorbing information and learning, it is up to adults to promote their learning and the development of many of their abilities. Didactic and educational toys are a good support in this training, helping them to develop all their skills in the development of imagination, memory, concentration and visual perception. In this paper, after an introduction to the contextual and theoretical framework, we briefly present the empirical methodology adopted in the practical project, which involved all the fieldwork developed in the toys company, the enquiries for selecting the product to study and promote, the different video creative and production stages; and the test and analyzes of reactions to the video prototype.
