Abstract
Roles can be used to overcome some composition limitations in Object Oriented Languages and contribute to a better code reuse, reducing code replication and improve code maintenance. Therefore, the refactoring of legacy code to roles is an important step in maintaining and evolving this code. In this paper, we present refactorings to convert a system to roles We also present some refactorings that enable roles to be even more reusable.

Abstract
Recent developments in the areas of augmented reality, 360 degrees panoramas, social networks and geographical information systems enable the development of new solutions, which can contribute to several areas. This paper presents a new, Unity3D [8] based framework for the development of immersive augmented reality solutions and 360 degrees panoramas. This solution allows the aggregation of spatial information from disparate and heterogeneous sources, comprising the visualization of points of interest (POIs), image overlays (photographs), 3D objects and navigation between panoramas. This framework also features a strong multiplatform (web and mobile) component, and the possibility of developing new functional modules that can be easily plugged in. A prototype based on this solution, for geomarketing, is also presented.

Abstract
This paper present the creation of a platform, highly scalable and modular, providing new services to the advertising and marketing for the catering industry, taking advantage of the spatial context and user preferences, benefiting from the advantages of Mobile Advertising and Mobile Augmented Reality.

Abstract
The present-day revival of Augmented reality (AR) technology has led to its vast expansion in various applications. In marketing, the hunt for more inventive and intriguing approaches for immersive consumer experiences has endorsed the implementation of AR in multiple brand advertising campaigns, specifically for improved product display. The engaging potential of this technology is established in the fusion between computer-generated data and the physical world as seen by the user, where 3D registration and real time interaction are inseparable parts of this system. Alternatively, impressions from user experiences serve as a principal instrument in the evaluation process of the effectiveness of interactive systems. In order to get deeper insight into consumers' reflections from a real-time AR shopping experience, we present a demo platform for the purchase of sneakers, focusing on users' behavior and more precisely on their perceptions, emotions, personal preferences before, during and after use of the platform. To fully evaluate and compare consumer experiences with the main AR platform, two other shopping systems were designed: a marker-based and a static one. Consecutively, we aim at defining a system of metrics for measuring shopping experiences with AR, as well as at establishing a ground base for subsequent marketing research in the field. Motivated by the large application of the technology and aiming at understanding the impact of AR on consumer psychology, the application will assist in exploring the antecedents of consumer purchase intentions.

Abstract
Augmented Reality (AR) is a technology which produces a synthesis between a computer-generated data and the physical world of a viewer while establishing 3D registration and real time interaction. Among the wide range of application of AR, its use in advertising shopping experiences has recently been embraced by advertisers due to its novelty and engaging potential. Part of a wider research aiming at understanding the impact of AR on consumer psychology, this paper presents a demo platform application developed for a real-time shopping experience for shoes and attempts to define a ground base for posterior marketing research in the field. In order to fully evaluate consumer experiences and compare with the main AR platform two other shopping applications were designed: a marker-based and a static one. The platform will assist in exploring the antecedents of consumer purchase intention and in defining metrics for measuring shopping experiences with AR.

Abstract
This paper describes the features and concepts behind the Command, Control and Intelligence (C2I) system under development in the ICARUS project, which aims at improving crisis management with the use of unmanned search and rescue robotic appliances embedded and integrated into existing infrastructures. A beneficial C2I system should assist the search and rescue process by enhancing first responder situational awareness, decision making and crisis handling by designing intuitive user interfaces that convey detailed and extensive information about the crisis and its evolution. The different components of C2I, their architectural and functional aspects are described along with the robot platform used for development and field testing.
