- Framework for the characterization of hotel websitesPublication . Correia, Marisol B.; Ramos, Célia M. Q.; Rodrigues, J. M. F.; Cardoso, Pedro J. S.Nowadays the importance of websites to the tourism and hospitality industries is fundamental. Hotels, for instance, spend a huge amount of money improving their websites to show all the activities and amenities that they can provide. There are studies to evaluate website performance based on functionality, usability and other factors; nevertheless, they are not exhaustive. This paper presents a framework for the characterization of hotel and resort websites, that was applied as a case study to the websites of 5-star hotels and resorts that operate in the tourism region of the Algarve, Portugal. This framework allows us to identify a set of features for the hotel and resort websites characterization. From these features, we propose a set of comprehensive indicators, grouping them into ten fundamental information dimensions, as well as the application of these indicators and information dimensions, which allows obtaining quantitative and qualitative results.
- Augmented reality and holograms for the visualization of mechanical engineering partsPublication . Figueiredo, Mauro; Cardoso, Pedro J. S.; Gonçalves, C. D. F.; Rodrigues, J. M. F.There is an increasing number of students using tablets in schools. Mobile devices gained popularity as an educational tool and there are many schools that use them frequently in educational activities to improve learning. We found that first year students of mechanical engineering in general have difficulties in understanding 3D shapes from 2D views. There are many Augmented Reality (AR) applications available that can be used to create educational contents for these mobile devices. On the other hand, there is an increasing interest in making holograms. In this paper we studied the most popular AR systems and show examples of using an AR system for the visualization of 3D models. We also present the creation of a low cost prototype, the EducHolo, that enables the visualization of holograms supported by tablets. With this prototype students can visualize the hologram of mechanical parts, providing a better perception of the model 3D shape and improving the ability of making the 2D orthographic views and perspectives that they study in the first year of mechanical engineer.
- A visual programming language for soccerPublication . Belguinha, António; Rodrigues, Pedro; Cardoso, Pedro J. S.; Rodrigues, J. M. F.; Paciência, DomingosThe use of Information Technologies (IT) in high competition sports is an instrument often used. However, the majority of the performers, including technical teams, do not have skills to program those IT tools to their needs. In this paper we present the low level implementation of a visual programming language (VPL) that allows the user without programming expertise to produce relatively complex programs by drawing them on a web application. The VPL tool application is illustrated by applying it to detect programmed situations from a soccer game, using previously obtained tracking data. The tool can be applied to other collective ball sports.
- A field, tracking and video editor tool for a football resource plannerPublication . Rodrigues, Pedro; Cardoso, Pedro J. S.; Rodrigues, J. M. F.The current Football Resource Planning (FRP) systems integrate both internal and external information management across the entire professional football organization, including features to gather automated information from the teams, not only on the competition part but also on the preparation. In this paper, we present three of those tools from the Footdata’s web/cloud FRP system: Field Editor (FE), Tracking Editor (TE) and Video Editor (VE). The FE provides the coach with a platform where he can represent the tactical movements for his team within an animated context. On the other hand, the TE allows the interaction with the Footdata tracking system. Finally, the VE tool offers the possibility for a coach to watch, cut and analyze football videos.
- Detection, classification and localisation of football players and ball from handycam videosPublication . Vilas, Tiago; Rodrigues, J. M. F.; Cardoso, Pedro J. S.The current performance requirements in football make imperative the use of new technologies for game observation and analysis, providing detailed information about the team's actions. This paper presents in resume an algorithm to collect information from Handycam videos, namely, the football pitch, player and ball detection, player classification within the team, the tracking and localisation of players and ball, being the main contribution the determination of the exact localisation of players and ball in the pitch.
- A computer vision based web application for tracking soccer playersPublication . Rodrigues, J. M. F.; Cardoso, Pedro; Vilas, Tiago; Mendes Da Silva, Bruno; Rodrigues, Pedro; Belguinha, António; Gomes, CarlosSoccer is a sport where everyone that is involved with it make all the efforts aiming for excellence. Not only the players need to show their skills on the pitch but also the coach, and the remaining staff, need to have their own tools so that they can perform at higher levels. Footdata is a project to build a new web application product for soccer (football), which integrates two fundamental components of this sport's world: the social and the professional. While the former is an enhanced social platform for soccer professionals and fans, the later can be considered as a Soccer Resource Planning, featuring a system for acquisition and processing information to meet all the soccer management needs. In this paper we focus only in a specific module of the professional component. We will describe the section of the web application that allows to analyse movements and tactics of the players using images directly taken from the pitch or from videos, we will show that it is possible to draw players and ball movements in a web application and detect if those movements occur during a game. © 2014 Springer International Publishing.

- Processing sports acquired information from a tracking systemPublication . Rodrigues, J. M. F.; Belguinha, António; Cardoso, Pedro J. S.In order to improve the players’ and teams' performances in sports, the technical staffs are now using an ever increasing number of technologies. In this paper we present a study based on a video tracking of players and ball, that can return heat, passes and ball losses maps, which can be a good resource to measure a player/team performance and a base to their improvement.
- Open source technologies involved in constructing a web-based football information systemPublication . Rodrigues, Pedro; Belguinha, António; Gomes, Carlos; Cardoso, Pedro J. S.; Vilas, Tiago; Mestre, Renato; Rodrigues, J. M. F.The current information systems and match analysis software associated to professional football output a huge amount of statistics. Many football professionals are particularly interested in real time information about the tactical plan occurring during the match, and the relations between that information and what was prepared in the training sessions. It is fundamental to have on the bench, and on-the-fly, the most relevant information each time they have to take a decision. In this paper, we present a set of open source technologies involved in building a multi-platform web based integrated football information system, supported in three main modules: user interfaces, databases, and the tactical plan detection and classification. We show that the selected technologies are suitable for those modules, allowing field occurrences to trigger meaningful information.
