For most of these domains, the large amount of information displayable on top of the reality, directly in the user's field of view, represents an important challenge for designers. In this paper we present a view management technique for placing touristic/cultural information, in the form of points of interest (POIs), in an AR system that works in the absence of a priori knowledge of the real environment. The user-driven view management technique, designed as a remote service, improves representation and displacement of the digital information each time the user manifests an interest in a particular area of the real space. The proposed approach includes a layout algorithm, which exploits the user's local position and her/his point of view direction, to correctly set the POI height in the user's view avoiding overlapping and cluttering, together with an adaptive rendering method, using information about the brightness of the area, that computes the visual appearance parameters of each virtual POI in order to improve its readability over the background.},

Ubiquitous Computing applications constitute a suitable solution for both reducing medical costs and improving patient safety by better supporting clinical processes. In this study we introduce an intelligent infrastructure for smart hospitals which implements basic services to optimize medical staff/patient interactions and grants ubiquitous and transparent access to clinical data stored in standard clinical databases. This infrastructure relies on the integration of Radio Frequency IDentification (RFID) and photosensor technologies to identify, locate and track clinicians and patients equipped with mobile devices and wearable RFID tags.},

The intelligent system has been developed at a prototypical stage and tested with a complex scenario created with a simulator.

We propose the use of RFID technology together with a conversational agent in order to implement a multimodal information retrieval service we call SensorMesh. The information acquired from RFID tags about the nearest point of interest is processed by the conversational agent that carries a more natural interaction with the user, also exploiting a common sense ontology. The service is accessible using a multimodal browser on Personal Digital Assistants (PDAs); the browser allows the user to interact with the conversational agent by means of spoken language instead of the traditional, keyboard- (or stylus-) based input systems. The resulting system offers a more natural interaction with respect to traditional prerecorded, audio-visual services, and it is particularly suitable for non technology-skilled users. textcopyright 2009 IEEE.},

The proposed solution consists in a distributed agent-based software infrastructure that grants a high level of transparency from the user point of view. As a matter of fact, accordingly with the Utility Computing model, the user has just to submit its tasks and their input parameters; after that, the software infrastructure takes care of (1) encapsulating tasks in mobile agents; (2) distributing them in the virtual environment; (3) launching and controlling execution; (4) picking up results; and (5) handling computing stations. Finally, it is important to note that the infrastructure is able to integrate both fixed and mobile hardware resources to build a community of computing stations for task executions. As a consequence, such an infrastructure can get useful computing power even from stations (mobile devices) that have always been neglected by classic task execution platforms.},
