Abstract
Prevalent in today society mobile devices indeed come with technical capabilities offering both complex software applications and location-based services. However, seldom are the mobile-devices software and hardware potential fully exploited, seen that the navigation-aid systems are the most ordinary and significant advantages being taken from such capabilities. Furthermore, bringing environment-contextualized information and services to users through their mobile-devices seems yet to be roughly explored as an electronic business. For example, when someone is on tour and spontaneously wants to find information, or want to book/buy tickets, concerning cultural events taking place in their geographical surroundings, up to present, it is not known an available system or service capable of providing it. To overcome this problem, we propose a new ubiquitous events promotion e-business system, which enables one to search for cultural events based on geographic location, also supporting ticket-booking, ticket-selling and ticket-validation services.

Abstract
Recent digital games have been developed not only for entertainment purposes, but also to promote learning. This paper presents MOW (Matching Objects and Words), which is an Augmented Reality (AR) game for learning words in different languages. Experimental tests were performed with Portuguese children during English classes. We have compared the results from using MOW along with traditional teaching methods. The results indicate that children who used the Augmented Reality games had a superior learning progress than those who used only traditional methods.

Abstract
Portugal started its "formal" path to the Information Society in 1997 with the creation of the "Green Paper on the Information Society". In 2000, the "Operational Programme for the Information Society" was created and based on three main pillars. Having been created as part of the second pillar, "Portugal Digital", the "Digital Cities and Regions" initiative, aimed at developing the Information Society on a regional basis. In this article an overview is made on the purposes and results of the projects incorporated in the "Digital Cities and Regions" initiative. The goals of several projects were analysed. From this analysis a summary chart and a brief discussion of the Goals of the Digital Projects were made.

Abstract
Technology has profoundly changed the way we learn and live. Indeed, such relationship appears to be quite complex, within IT contexts, and especially in socially and technologically rich learning environments, where related skills and learning are progressively required and fostered. Thus, if a satisfactory level of intellectual performance and social competence of a primary school pupil is indeed highly dependent on the type of participation that parents offer their children, IT, in general, and Internet, in particular, may well provide a new paradigm, setting forth that education and communication approach is truly more complex than ever before. It is on the basis of such paradigm that we therefore present a case study where a set of multimedia exercises were used in order to possibly improve the mathematical skills of pupils, one with mental retardation and another with cerebral palsy. Being part of a Web-based system to support students' learning, the referred set of multimedia exercises proved to be the children's favorite, rather than exercises in paper form, which also led the children to show a fair more positive attitude towards learning. Also, we observed that through the mentioned multimedia exercises, the children became far more autonomous, interested, persistent, happy, and able to easily absorb the material as well as more willingly to continue on working.

Abstract
Information and Communication Technologies (ICTs) are considered a powerful tool for economic development and the growth of societies. However, instead of helping overcome society's inqualities caused by the digital era, they have instigated an increase of the people that rested aside of the information age. The digital divide refers to the difficulty info-excluded people have in keeping up with technological advances. This phenomenon was triggered by the rapid growth and dissemination of technological equipment, as a portion of society did not have the proper time or knowledge to adjust. This paper sets forth a new approach to help fight the Portuguese digital divide by presenting new ways of interaction. Resorting to multi-touch technology, we examine how this new natural interaction paradigm can have a positive influence in the struggle against info-exclusion. For this purpose, we present a multi-touch game envisioned to encourage and teach digitally excluded people on how to use an important and needed everyday equipment - the ATM (Automated Teller Machine) - as it is still avoided by some. We believe that our pilot case study can show preliminary results on how natural user interfaces may be beneficial to help overcome some difficulties enforced by the digital divide. We consider that our findings may be valuable to show a possible path of how the new natural user interfaces can help bring technology and people closer. After being asked about their user experience, the participants of this exploratory study agreed that the game encouraged them to explore more about new technologies. (C) 2012 The Authors.

Abstract
The use of Information and Communication Technologies (ICTs) has grown substantially over the past few years. However, a portion of the world's society has not been able to keep up with these technological advances. For this purpose, we present a serious game with a multi-touch interface envisioned to encourage and teach digitally excluded people on how to use the Portuguese Automated Teller Machine (ATM): a commodity much needed by society, but still avoided by some, mainly due to their fear of the digital world. An exploratory study was conducted to investigate if a serious game based on a new interaction paradigm can have a positive influence in the struggle against the Portuguese digital divide. We believe that the findings of our pilot case study can be useful to determine if a multi-touch serious game, due to its intuitiveness and ease of use, can stimulate the digitally excluded people to handle the ATM on a regular basis. The results that were obtained suggest that this approach may indeed produce a positive impact in the attempt to bridge the Portuguese digital divide.
