While task modeling and task-based design are entering into current practice in the of interactive software applications, there is still a lack tools supporting development analysis models. Such should provide developers with ways to represent tasks, including their attributes objects temporal semantic relationships, easily create, analyze, modify such representations simulate dynamic behavior. In this paper, we present tool, CTTE, that provides thorough support for developing analyzing...

The increasing availability of new types interaction platforms raises a number issues for designers and developers. There is need methods tools to support development nomadic applications, which can be accessed through variety devices. We present solution, based on the use three levels abstractions, that allows focus relevant logical aspects avoid dealing with plethora low-level details. have defined transformations able obtain user interfaces from such taking into account available their...

One important evolution in software applications is the spread of service-oriented architectures ubiquitous environments. Such environments are characterized by a wide set interactive devices, with that exploit number functionalities developed beforehand and encapsulated Web services. In this article, we discuss how novel model-based UIDL can provide useful support both at design runtime for these types applications. service annotations also be exploited providing hints user interface...

Our life is characterized by the presence of a multitude interactive devices and smart objects exploited for disparate goals in different contexts use. Thus, it impossible application developers to predict at design time users will exploit, how they be arranged, which situations objectives used. For such reasons, important make end able easily autonomously personalize behaviour their Internet Things applications, so that can better comply with specific expectations. In this paper, we present...

Model-based approaches can be useful when designing nomadic applications, which accessed through multiple interaction platforms. Various models and levels of abstraction considered in such approaches. The lack automatic tool support has been the main limitation to their use. We present a tool, TERESA, supporting top-down transformations from task abstract user interfaces then for different types platforms (such as mobile phones or desktop systems). It allows designers keep unitary view...

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 included in addition the and artwork descriptions. The mobile is equipped with an RFID reader, which detects nearby tagged artworks. By taking into account context-dependent information, including current user position behaviour history, as well type device available, more personalised relevant information provided...

In the coming years humanoid robots will be increasingly used in a variety of contexts, thereby presenting many opportunities to exploit their capabilities terms what they can sense and do. One main challenge is design technologies that enable those who are not programming experts personalize robot behaviour. We propose an end user development solution based on trigger-action personalization rules. describe how it supports editing such rules its underlying software architecture, report test...

In this paper, we present a framework for describing various design dimensions that can help in better understanding the features provided by tools and applications multi-device environments. We indicate possible options each dimension, also discuss how research proposals area are located our framework. The final discussion points out important areas future research.

The ever-increasing availability of new types devices raises a number issues for user interface designers and interactive software developers. We have designed developed model-based authoring environment (TERESA), which provides support when designing developing interfaces accessible through various device in Web-based environment.

The availability of mobile and stationary devices opens up new challenges to support users in several contexts. Here we present a multi-device environment cooperation among museum visitors through games. In particular, design the associated implementation for using combination PDAs public displays enhance learning experience setting by game playing interactions. basic assumption is use individual play, situated synchronized views shared play; play contributes game.

In this paper, we present an environment for authoring pervasive multimodal user interfaces. It is composed of a set XML-based languages, transformations among such and tool. provides designers with the possibility designing interfaces wide platforms, which support various modalities. We describe how has deeply changed from initial mono-modal, web-oriented provide example applications number platforms.

This paper presents a new interaction technique - scan and tilt aiming to enable more natural with mobile museum guides. Our work combines multiple modalities gestures, physical selection, location, graphical voice. In particular, selection is obtained by scanning RFID tags associated the artworks, gestures are used control navigate user interface multimedia information. We report on how it has been applied guide in order enhance experience, providing details first test carried out our prototype.
