Within recent years, there is an increasing need to train students, from biology and beyond, in quantitative methods that are relevant to cope with data-driven biology. Systems Biology is such a field that places a particular focus on the functional aspect of biology and molecular interacting processes. This paper deals with the conceptual design o...

In this article we present a new approach for supporting people in their daily encounters with technology. Be it at home, in public spaces or on the road, people often need to solve little puzzles when facing new technology in order to carry out a task. Furthermore, help is seldom available or is hard to understand. In this article we present a new...

Smart environments offer a vision of unobtrusive interaction with our surroundings, interpreting and anticipating our needs. One key aspect for making environments smart is the ability to recognize the current context. However, like any human space, smart environments are subject to changes and mutations of their purposes and their composition as p...

The vision where living and working spaces adapt to people is becoming a reality thanks to the increased embedding of computing power into everyday objects. Ambient learning focuses on the way people adopt technology in their everyday life and how technology adapts to the environment. Ambient learning is a new area in ubiquitous computing (UC) abou...

Location-aware software has become widespread outdoors. Indoor applications are now on the rise. However, careful selection of the appropriate local positioning system (LPS) and application fine-tuning are required in order to guarantee acceptable user experience. We present a simulation-based approach that includes application characteristics, LPS...

Over the past few years, several technological advances have been made to enable locating people in indoor settings, where way finding is something we do on a daily basis. In a similar way as it happened with GPS and today’s popular outdoor navigation systems, indoor navigation is set to become one of the first, truly ubiquitous services that will...

The Mundo project at the Telecooperation Group is concerned with general models and architectures for ubiquitous computing. The Mundo Smart Environments system provides the necessary core services and tools to build applications for such environments. While the development of single services is common practice, the matter of how to coordinate servi...

In this paper we argue that Web applications are a particular kind of hypermedia application and show how to model their navigational structure. We argue that if we need to design applications combining hypermedia navigation with complex transactional behaviors (as in E-commerce systems), we need a systematic development approach. We present the ma...

One of the main challenges in ubiquitous computing is mak- ing users interact with computing appliances in an easy and natural manner. In this paper we discuss how to turn or- dinary devices into Smart Products that are more intuitive to use and are self-explanatory. We present a general archi- tecture and a distributed runtime environment for buil...

Next, we present our view on the design process of context-aware software; we introduce design patterns and explain why they can be usef...

Nowadays, the design of efficient speech interfaces is considered to be more an art than an engineering science. Several guidelines exist, but are more or less hints about what should be avoided. We intro- duce a first set of patterns integrating many guidelines and solution approaches developed during the past 15 years. Our goal is to docu- ment a...

In this paper we present a modeling approach for building physical hypermedia (PH) applications, i.e. those applications in which real and digital objects are navigated using the hypertext paradigm. We first survey the state of the art in this kind of ubiquitous applications. We stress the importance of modeling and design activities and present ou...

A plethora of context infrastructures have been devel- oped to support the deployment of context-aware systems. Unfortunately, it is not easy to re-use the design prin- ciples adopted in a certain context infrastructure in or- der to leverage some characteristics of another one, as such principles are often hidden into the infrastructure and not in...

The future mobile and ubiquitous computing world will need new forms of information sharing and collaboration between people. In this paper we present iClouds, an architecture for spontaneous mobile user interaction, collaboration, and transparent data exchange. iClouds relies on wireless ad hoc peer-to-peer communications. We present the iClouds a...

Introduction Documents, sites and in general applications in the World-Wide Web are undergoing constant evolution. Yet we would argue that not everything changes but that a large proportion of design decisions are of lasting quality. We propose that such design decision be captured explicitly through complimentary use of design patterns in design m...

We next review some Web patterns that can be used in E-commerce applications. Finally, we present five new patterns: Opportunistic Linking, Advising, Explicit Process, Easy Undo and...

Designing high quality visual interfaces for hypermedia applications is difficult; it involves organizing different kinds of interface objects (for example those triggering navigation), prevent lhe user from cognitive overhead, etc. Unfortunately, interface design methods do not capture design decisions or rationale, so it is hard to record and con...

In this paper we present a software engineering approach for building hypermedia applications. Our approach combines the use of an object-oriented method with a system of design patterns for navigational and interface design. We first present the core activities in the Object-Oriented Hypermedia Design Method (OOHDM), namely conceptual design navig...

Zusammenfassung: Das Web entstand als extrem simples, aber weltweite Links unterstützendes Hyper-textsystem. Dieses »Erfolgsrezept Einfachheit« stellt den Einsatz ausgereifter Design-Methoden und –Werkzeuge für Hypertext-/Hypermedia bis heute in Frage. Erst mit XML werden »ausgewachsene« Hypertextsysteme möglich, sind aber noch lange nicht üblich....
