In this paper, we propose UbiCicero, a multi-device, location-aware museum guide able to opportunistically exploit large screens when users are nearby. Various types of games are included in addition to the museum and artwork descriptions. The mobile guide is equipped with an RFID reader, which detects nearby tagged artworks. By taking into account(More)
In this work, we report on a solution for providing support to the blind using mobile museum guides by exploiting the haptic channel as a complement to the audio/vocal one. The overall goal is to improve the autonomy and social integration of blind visitors. We followed an iterative approach in which the proposed system went through various user evaluations(More)
Current authoring environments provide the possibility of developing user interfaces with limited adaptation capacities. The most widely adopted tools follow the responsive design approach and allow developers to obtain user interfaces that can adapt mainly to the screen size and orientation. We present a solution able to support development of user(More)
In this work we present an environment able to support users in seamless access to Web applications in multi-device contexts. The environment supports dynamic push and pull of interactive Web applications, or parts of them, across desktop and mobile devices while preserving their state. We describe mechanisms for sharing information regarding devices,(More)
In this paper, we propose a multi-device, location-aware museum guide. It is a mobile guide able to opportunistically exploit large screens when they are nearby the user. Various types of games, which can exploit multi-device environments, are included in addition to the museum and artwork descriptions. The mobile guide is equipped with an RFID reader,(More)
Ubiquitous environments call for user interfaces able to migrate across various types of devices while preserving task continuity. One fundamental issue in migratory user interfaces is how to preserve the state while moving from one device to another. In this paper we present a solution for the interactive part of Web applications. In particular, we focus(More)
In this paper, we present a study aiming to investigate how tilt-based interaction, along with RFIDs for localization, can be exploited to support blind users in interacting with mobile guides. We describe the design proposed and report on a first user study, which also compared two different ways to provide audio feedback (short sounds or vocal messages)(More)
The creation of service front ends able to adapt to the context of use involves a wide spectrum of aspects to be considered by developers and designers. A context-aware adaptation enabled application needs a simultaneous management of very different application functionalities, such as the context sensing, identifying different given situations, determining(More)
