Abstract [en]

The way we interact with computers and computer systems are constantly changing as technology evolves. A current trend is that users interact with multiple andinterconnected devices on a daily basis. They are beginning to request ways and means of dividing and spreading their applications acrossthese devices.Distributed user interfaces (DUIs) have been proposed as a means ofdistributing programs over multiple interconnected devices through theuser interface (UI). DUIs represent a fundamental change foruser-interface design, enabling new ways of developing distributedsystems that, for instance, support runtime reorganization ofUIs. However developing DUIs presents a far more complex task compared totraditional UI development, due to the inherent complexity thatarises from combining UI development with distributed systems. Thetraditional approach in software engineering and computer science toovercoming complexity is to build tools and frameworks, to allowfor good code reuse and higher level of abstraction for applicationprogramers.Conventional GUI programming tools and frameworks are not developedto support DUIs specifically. In this thesis we explore key issues increating new programming tools and frameworks (APIs) for DUI-based UIdevelopment. We also present and discuss the DUI framework Marve,which adds DUI support to Java Swing.A unique feature of Marve is that it is designedfor industrial-scale development, extending a standard UIframework. The framework has beentested and evaluated in a project where an operator control stationsystem was developed.

Abstract [en]

High-fidelity simulations of pandemic outbreaks are resource consuming. Cluster-based solutions have been suggested for executing such complex computations. We present a cloud-based simulation architecture that utilizes computing resources both locally available and dynamically rented online. The approach uses the Condor framework for job distribution and management of the Amazon Elastic Computing Cloud (EC2) as well as local resources. The architecture has a web-based user interface that allows users to monitor and control simulation execution. In a benchmark test, the best costadjusted performance was recorded for the EC2 H-CPU Medium instance, while a field trial showed that the job configuration had significant influence on the execution time and that the network capacity of the master node could become a bottleneck. We conclude that it is possible to develop a scalable simulation environment that uses cloud-based solutions, while providing an easy-to-use graphical user interface.

The resulting protocol (NCT01205191 at clinicaltrials.gov) for use in frontline clinical practice in which effectiveness, adherence, and the role of the therapists are analyzed, provides evidence for what are truly valuable cell phone-supported CBT treatments and guidance for the broader introduction of CBT in health services.

Abstract [en]

Distributed User Interfaces (DUIs) provide new degrees of freedom to the distribution of systems. This work presents a seamless way for developers to handle the event communication structure much in the same way as in traditional applications. Our framework Marve is the externalization experience of developing several DUI systems. To evaluate our framework we developed a DUI system together with SAAB Aerosystem Human-Machine Interaction division. Using our approach to develop the sample application we show that the current model for development of UIs can be extended to incorporate support for DUI development

Abstract [en]

Objectives: Ubiquitous computing with multiple interaction devices requires new interface models that support user-specific modifications to applications and facilitate the fast development of active workspaces.

Methods: We have developed NOSTOS, a computer-augmented work environment for clinical personnel to explore new user interface paradigms for ubiquitous computing. NOSTOS uses several devices such as digital pens, an active desk, and walk-up displays that allow the system to track documents and activities in the workplace.

Results: We present the distributed user interface (DUI) model that allows standalone applications to distribute their user interface components to several devices dynamically at run-time. This mechanism permit clinicians to develop their own user interfaces and forms to clinical information systems to match their specific needs. We discuss the underlying technical concepts of DUIs and show how service discovery, component distribution, events and layout management are dealt with in the NOSTOS system.

Conclusion: Our results suggest that DUIs - and similar network-based user interfaces - will be a prerequisite of future mobile user interfaces and essential to develop clinical multi-device environments. © 2005 Elsevier Ireland Ltd. All rights reserved.

Abstract [en]

The television (TV) is one of the most common entertainment devices in homes. Searching and finding TV programs is a common task and using TV guides is one way of performing this. This paper presents three studies that are focused on examining audiences’ TV habits and TV guide usage, evaluating a new concept based on linking paper and pen with TV technology, and studying the audiences’ attitudes toward and anticipated interest in the future guide. The results of our first study emphasize the value of using paper based TV guides and also identify the deficiencies. We also found indications that the advantages and disadvantages of paper-based TV guides are related to the physical properties of paper. Thus, we suggest a solution that uses digital pen and paper technology to offer a new interaction method for TV. A research system “Paper Remote”, is developed and used in the two subsequent studies. Viewers tick designated areas on the paper-based guide to perform actions such as channel switching. However, this solution is not a substitute for the remote control device. We argue that these user studies on linking digital paper to the TV for everyday information navigation illuminate the possibilities of providing innovative solutions also for home information systems also.

Abstract [en]

Ubiquitous computing environments can support clinical administrative routines in new ways. The aim of such computing approaches is to enhance routine physical work, thus it is important to identify specific design requirements. We studied healthcare professionals in an emergency room and developed the computer-augmented environment NOSTOS to support teamwork in that setting. NOSTOS uses digital pens and paper-based media as the primary input interface for data capture and as a means of controlling the system. NOSTOS also includes a digital desk, walk-up displays, and sensor technology that allow the system to track documents and activities in the workplace. We propose a set of requirements and discuss the value of tangible user interfaces for healthcare personnel. Our results suggest that the key requirements are flexibility in terms of system usage and seamless integration between digital and physical components. We also discuss how ubiquitous computing approaches like NOSTOS can be beneficial in the medical workplace.

Abstract [en]

Mobile and ubiquitous computing require new approaches to user interface design. Incorporating I/O devices in the environment is imperative because small devices do not provide enough interaction richness. Distributed user interfaces (DUIs) are needed to take advantage of such I/O-landscapes.

A DUI constitutes a fundamental change of the pretext of user interface development. New programming models that support efficient creation and maintenance may be required. This paper presents a case study in DUI design and report on the use of current GUI modeling techniques to provide DUIs. We identified several issues where current programming models need to be extended.
