User involvement is widely recognized as best practice in the development of information technology (IT) systems. In large-scale IT projects, the involvement of users and other stakeholder groups is typically in the form of representatives, as opposed to the direct (in-person) participation characteristic for smaller projects. The potential new sha...

Studies indicate that the way structured participatory design activities are facilitated significantly effects participation, power relations, and generated output. Although facilitation is always adapted to the conditions of each design project, the way facilitation is enacted primarily depends on the individual facilitator. It is assumed that ena...

This paper provides a systematic review of research articles published between 2010 and mid-2018 that have offered design guidelines for full-body interactive games for recreational purposes and physical exercise. From an initial 3562 retrieved database references, 22 articles were found to meet our predefined criteria and were included in the fina...

Background: Currently, exergames are used by different age groups for both recreational and training/rehabilitation purposes. However, little is known about how to design exergames so that they are motivating for specific age groups and health outcomes. Objective: In this article, we compare motivational factors between healthy young and older adu...

We describe the results from a Norwegian case study of the attitudes of community-dwelling lung patients and health response center personnel toward a telecare service for such a patient group. The telecare service was intended to prevent exasperations in patients and employed a digital self-report application for remote monitoring of patients' hea...

Health and welfare organisations are under increased scrutiny regarding their ability to make innovations in and increase the productivity of their services by digitising and automating them. Our empirical case study focuses on the implementation of a new health and welfare surveillance infrastructure project in a large Norwegian municipality. The...

This article explores care stakeholders’ perspectives on how interactive technology can help form socially active environments in residential care settings. Based on participatory workshops, involving representatives from multiple stakeholder groups, the authors identify a set of considerations relevant for design of social inclusion technology for...

Patient-centered care encourages active involvement of patients in their own treatment and a collaborative perspective on the relationship between patient and practitioner. However, to achieve constructive patient-practitioner collaboration in medical consultations the partakers need to successfully interact across conceptual boundaries that can im...

Purpose: Our purpose is to provide insight into the added value of applying a participatory design approach in the design of an interactive sound environment simulator to facilitate communication and understanding between patients and audiologists in consultation situations. Method: We have applied a qualitative approach, presenting results and...

This paper explores how interactive technology can help overcome barriers to active patient participation in audiological consultations involving hearing aid tuning.

The municipality of Trondheim in Norway has in the recent years experimented with location technologies applied to tracking and localization of people with cognitive impairment. Earlier R&D projects helped sketch a service model. A number of GPS-related technologies were also piloted and tested in these R&D projects. Since Spring 2015 the municipal...

This paper provides an empirical understanding of concerns that the application of a sensor-enhanced medical alert system, or personal emergency response (PER) system, raises from the perspective of care receivers (users) and care providers. Data were gathered in the context of a field trial of a PER system supporting both user-initiated alerts and...

People suffering from COPD commonly experience exacerbations leading to hospital admissions. mHealth technologies holds a potential for improved healthcare delivery to this group, with a possible impact on preventing COPD exacerbations. Designing appropriate technology and services for people with COPD requires an in-depth understanding of their ne...

Patients with advanced cancer are influenced by the disease itself and by treatment side effects, both of which may have great impact on their lives. One of the most distressing symptoms is pain. However, pain in cancer patients can in most cases be relieved if the patient is able to communicate the nature and severity of the problem to the healthc...

Fall risk and fall-related injuries increase with age. With an aging population, we need to have a better understanding of what solutions can help us cope with age-related falls. Ambient and ubiquitous fall technologies engage a large research community. We wanted to map research that has been done, technology that is developed and/or applied, curr...

Background: Exergames are increasingly used as an exercise intervention to reduce fall risk in elderly. However, few exergames have been designed specifically for elderly, and we lack knowledge about the characteristics of the movements elicited by exergames and thereby about their potential to train functions important for fall risk reduction. O...

Active patient participation in audiological treatment is central in improving the benefits and satisfaction that patients experience in the use of hearing aids. However, involving patients in their own treatment is challenging. Clinics often lack appropriate tools for information sharing and collaboration between patients and audiologists. In addi...

Falls in older people constitute one of the major challenges in healthcare. It is important to design technologies that can help prevent falls and im-prove falls management. Smart home technology could be of importance in this con-text, but the technology has to be user-centred or adapted to be useful in this particu-lar context. This study assesse...

Advanced cancer patients often have a high symptom burden and reduced functional status, which implies that the patients themselves need to be involved in development and testing of interactive assessment tools for this patient group. This paper reports on an assessment of different aspects of use which led to changes in both medium and program in...

This paper presents an attempt to understand how safe walking technology can be designed to fit the needs of people with dementia. Taking inspiration from modern dementia care philosophy, and its emphasis on the individual with dementia, we have performed in-depth investigations of three persons' experiences of living with early-stage dementia. Fro...

Designing for the sickest and frailest cancer patients requires an even higher level of user involvement than traditional software development. This paper reports on design and evaluation of a pain assessment tool, where changes of the deployment platform from paper, via laptop to iPad affect the interaction with the tool. We also show how changes...

Ambient assistive technology (AAT) is envisioned as a powerful tool for facing the growing demands the demographic change toward an aging society puts on care. While AAT is often expected to increase the quality of life of older people, this paper holds that relevant interventions often embody values that can contradict such visions, and in some ca...

This paper investigates the attitudes of professional stakeholders involved in dementia care to GPS tracking of dementia patients. Data were gathered via focus groups that met in the context of a field experiment in which patients' spatial activities were tracked using GPS. Four main topics emerged: (1) different perspectives on the purpose of the...

We investigate a conventional GPS tracking system employed in professional dementia care in search of value biases that contradict central care values. The investigation follows the formal steps of the value-sensitive design approach. Four biases are identified. These are related to: augmentation, privacy, self-esteem, and trust and accountability....

Part of this work includes focus group inter- views with role models, do...

This chapter presents results and experiences from the MOBEL (MOBile ELectronic patient record) project at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. MOBEL was a multidisciplinary research project established in 2000. The problem area of the project was communication and information needs in hospital wards, and...

Recent studies on usability assessment methodology suggest that features of real-word use settings can be replicated in laboratories in order to combine realism with a high level of control. The field of human-computer interaction, however, lacks theoretical foundation for how to design well scoped and targeted in sitro, or simulation-based usabili...

Controlled laboratory-based usability assessments of mobile information and communications technologies (ICT) for hospitals have been conducted. As part of these assessments, clinicians have acted out mobile work scenarios and used the systems to solve related tasks. The evaluations show that relevant usability issues go beyond those of graphical u...

We have applied full-scale simulations to evaluate the usability of mobile ICT for hospitals in a realistic but controllable research setting. Designing cost-effective and targeted simulations for such a purpose raises the issue of simulation fidelity. Evaluators need to identify which aspects of the research setting that should appear realistic to...

The dynamic nature of clinical work makes it challenging to assess the usability of mobile information and communication technology (ICT) for hospitals. To achieve some of the realism of field evaluations, combined with the control of laboratory-based evaluations, we have conducted usability tests of prototypes in a laboratory custom designed as a...

In this section we will briefly discuss how the presented modeling technique can contribute to inform design of ubiquitous computing and smart spaces. We will also point out some limitations. 6.1 Main Contributions De facto computer system modeling formalisms tend to remove physical features of the system that is modeled. This makes it difficult to...

While much is known about how to do usability testing of stationary Electronic Patient Record (EPR) systems, less is known about how to do usability testing of mobile ICT systems intended for use in clinical settings. Our aim is to provide a set of empirically based recommendations for usability testing of mobile ICT for clinical work. We have cond...

This paper explores the distinctive features of designing smart technology for domestic environments. Because human-computer interaction in digitally augmented home environments is likely to be highly situated, we argue that providing flexibility with regard to method of interaction is a central issue for realization the smart home concept. Framing...

This paper compares the usability of some location and token-based interaction techniques for systems that provide point-of-care access to medical information. The investigation is based around a scenario from clinical work—administration of medicine to patients. Four interaction techniques that match the scenario are identified. We demonstrate how...

Location and token-based methods of interaction form two broad sets of interaction techniques for ubiquitous computing systems. Currently there are few tools available that allow designers to pay attention to the physicality that characterizes human-computer interaction with such systems, and how users experience them. This paper reports on ongoing...

This paper introduces a visual formalism for modeling location and token-based user interaction in context-aware environments. As computer technology is embedded into our surrounding environments and interaction is moved into the physicality of the real world, we argue that there is a need for effective methods that allow designers to model systems...

The current article investigates the affordances associated with paper out of the motivation that this can help inform design of pervasive and ubiquitous computing solutions for clinical use. In particular, we focus on paper-based medication charts, and discuss how these artifacts differ from various digital and context-aware solutions both in term...

This paper aims to explore how computerized interpersonal information can be mediated through the physical environment of hospital wards. Specifically, it focuses on a communication service (location-based virtual notes) that allows hospital workers to leave short digital messages at relevant physical locations (e.g. by a patient bed), so that inte...

The hospital ward is a highly dynamic work environment, in which healthcare personnel rapidly switch from one task to another. The process is partly planned, and partly driven by events and interrupts. A mobile electronic patient chart (MEPC) will be an important tool for supporting order entry and accessing, communicating, and recording clinical i...
