SOCIAL WEB: PROSPETTIVE ECONSIDERAZIONI

L\u2019avvento del Web 2.0 ha reso fruibile ai pi\uf9 uno strumento di comunicazione che, in precedenza, richiedeva un significativo background tecnologico. Tuttavia, questa evoluzione ha causato anche fenomeni come la disgregazione cognitiva, lo svuotamento del concetto di \u201ctrust\u201d e l\u2019aumento della frammentariet\ue0 dell\u2019informazione stessa. In questo articolo presenteremo l'evoluzione storica del social web e gli aspetti tecnologici che l'hanno veicolata. Affronteremo poi gli aspetti oscuri sopra citati e, parallelamente, i recenti sviluppi della sicurezza informatica nei sistemi di social networking

Memory Support through Pervasive and Mobile Systems

Memory is one of the most important components of human self-consciousness. As such, it has always been the subject of scientific studies and is one of the human functionalities with the most ancient examples of prosthetic devices. In this chapter we will describe the evolution of memory prosthetic devices from the paper agenda to the modern context-aware and mobile systems, and we will describe how our system, with its capability to autonomously recognize locations where a user may efficiently perform a previously defined task, represents a significant innovation with respect to the state of the art. Finally, we will describe our experimental results and we will provide some concluding remarks

Pervasive Services and Mobile Devices May Support Human Memory and Enhance Daily Efficiency

The recent developments in mobile devices may be exploited to deliver to human users a host of efficiency enhancement services. Among all the possible services, we argue that support for human memory is definitely a critical one, as a matter of fact memory is at the basis of most cognitive skills. The building of a service capable of supporting human memory requires complex computational tasks that are still beyond the capabilities of current mobile devices, however the ready availability of broadband connectivity allows weaving together server side computational power with client side rich content delivery. In this paper we provide a complete description of the different components of the 4W (what-where-when-who) project and its reference implementation system. The system provides a service capable of mitigating the negative effects of stress or aging on the memorization capability of humans leveraging both client side and server side state of the art solutions. The 4W (what-where-whenwho) prototype is capable of capturing user needs and to-dos, reason to identify where those needs and tasks can be fulfilled/performed in an efficient way and provide timely and localized hints about the identified sweet-spots. We have tested with real users both the general efficacy of the system and the different level of efficiency of several hint-notification modes, thus we present of our results and we provide a discussion of our findings

eLaparo4D: A Step Towards a Physical Training Space for Virtual Video Laparoscopic Surgery

The paper presents the preliminary implementation of eLaparo4D, an immersive training space designed for videolaparoscopic surgery. This is a low-cost training space which integrates haptic devices with realistic surgery tools and 3D rendering with physically deformable 3D CG models of the human internal organs. The main objective of the eLaparo4D first prototype is to design effective training exercises for medicine students within a realistic scenario of a videolaparoscopic operating room. The simulator is based on a client/server layered architecture in order to act as a sort of data gateway: the hardware is interfaced with the physics 3D engine to obtain real-time performances, with an HTML5-based 3D output visual interface in order to integrate the tracking of operating sessions within a custom training platform

LOW-COST LAPAROSCOPIC SIMULATION: Genoa operative Advanced Laparoscopic Simulator \u201cG.O.A.L.S.\u201d for acqiring laparoscopic abilities

This study proposes a curriculum tailored to each trainer's needs . The result\u2019s data analysis will be possible only after a period of testing of the simulator on different samples of students. Referring to experience from other groups, we expect significant results in terms of: reduction of learning time, better dexterity and ability to manage possible procedural error
