    A visualization paradigm for 3D map-based mobile services
    ( 2010) Mário Freitas ; Augusto Sousa ; António Coelho
    Nowadays, there is a wide range of commercial LBMS (Location- Based Mobile Services) available in the market, and a trend towards the display of 3D maps can be clearly observed. Given the complete disparity of ideas and a visible commercial orientation in the industry, the study of the visualization as- pects that influence user performance and experience in the exploration of urban environments, using 3D maps, becomes an important issue. Based on a proposed conceptual framework, an online questionnaire was developed and administered in order to measure the real impact of each element. Combining the experimental results with the current state-of-the-art, a new visualization paradigm is defined in a dual specification: 'layers' providing relevant visual content to the map, and 'functions' providing the necessary functionality.

    Term Weighting based on Document Revision History
    ( 2011) Sérgio Nunes ; Cristina Ribeiro ; Gabriel David
    In real-world information retrieval systems, the underlying document collection is rarely stable or definitive. This work is focused on the study of signals extracted from the content of documents at different points in time for the purpose of weighting individual terms in a document. The basic idea behind our proposals is that terms that have existed for a longer time in a document should have a greater weight. We propose 4 term weighting functions that use each document's history to estimate a current term score. To evaluate this thesis, we conduct 3 independent experiments using a collection of documents sampled from Wikipedia. In the first experiment, we use data from Wikipedia to judge each set of terms. In a second experiment, we use an external collection of tags from a popular social bookmarking service as a gold standard. In the third experiment, we crowdsource user judgments to collect feedback on term preference. Across all experiments results consistently support our [...]

    Assessing driver's mental representation of Adaptive Cruise Control (ACC) and its possible effects on behavioural adaptations
    ( 2012) Giulio Piccinini ; Carlos Rodrigues ; Anabela Simões ; Miguel Leitão
    The introduction of Adaptive Cruise Control (ACC) could be very helpful for making the longitudinal driving task more comfortable for the drivers and, as a consequence, it could have a global beneficial effect on road safety. However, before or during the usage of the device, due to several reasons, drivers might generate in their mind incomplete or flawed mental representations about the fundamental operation principles of ACC; hence, the resulting usage of the device might be improper, negatively affecting the human-machine interaction and cooperation and, in some cases, leading to negative behavioural adaptations to the system that might neutralise the desirable positive effects on road safety. Within this context, this paper will introduce the methodology which has been developed in order to analyse in detail the topic and foresee, in the future, adequate actions for the recovery of inaccurate mental representations of the system.

    A method to investigate drivers' Acceptance of Blind Spot Detection System
    ( 2012) Anabela Simões ; Giulio Piccinini ; Miguel Leitão ; Carlos Rodrigues
    Lately, with the goal of improving road safety, car makers developed and commercialised some Advanced Driver Assistance Systems (ADAS) which, through the detection of blind spot areas on the vehicle's sides, could help the drivers during the overtaking and the change lane task. Despite the possible benefits to reduce lateral crashes, the overall impact on road safety of such systems have not been deeply studied yet; notably, despite some researches have been carried out, there is a lack of studies regarding the long-term usage and drivers' acceptance of those systems. In order to fill the research gap, a methodology, based on the combination of focus groups interviews, questionnaires and a small-scale field operational test (FOT), has been designed in this study; such a methodology aims at evaluating drivers' acceptance of Blind Spot Information System® and at proposing some ideas to improve the usability and user-friendliness of this (or similar) device in their future development.

    E-BUSINESS MATURITY: CONSTRAINTS ASSOCIATED WITH THEIR EVOLUTION
    ( 2012) José Pires ; Ramiro Gonçalves ; Elisabete Morais
    To compete effectively in the e-business world, an organization must structurally transform its internal foundation. This structural change requires an organization to develop an innovative e-business strategy, focusing on speed to market and breakthrough execution. Despite the recognition and care that in recent years has been dedicated to e-business, there remains a need for continuing research efforts that seek to better understand constraints on the evolution of an organization to a state that can take advantage of e-business possibilities. There is a special need for this when considering small and medium enterprises, or businesses in developing countries. To minimize risk exposure from e-business initiatives, it is imperative for an organization to identify potential constraints on e-business evolution. In this setting, we develop a research model that involves e-business constraints and e-business maturity. We classify the constraints into the categories of environment constraints, organizational constraints, and technological constraints. Our results indicate that there are constraints that can be more or less problematic, depending on the stage of maturity. The results are also quite different in large organizations versus Small and Medium Enterprises.
