- This study presents insights from using requirements gathering techniques for country-specific customization of smart phones in two emerging markets, Iran and Turkey. In each country, a group of users participated in requirements gathering sessions that were aimed at developing design ideas for overcoming country-specific usability problems. Using qualitative content analysis, it was found that in each country some specific interaction activities were considered more when participants generated design ideas for country-specific usability problems. It was also found that even for similar usability problems, participants suggested country-specific solutions. Therefore, it is suggested that participation of local users in the design process should not be limited to identification of usability problems, but should also include the problem-solving phase that is usually a phase in design and development processes in which requirements gathering techniques are being used.

- Implementing information and communications technology (ICT) at scale requires evaluation processes to capture the impacton users as well as the infrastructure into which it is being introduced. For older adults living with cognitive impairment, thisrequires evaluation that can accommodate diferent levels of cognitive impairment, alongside input from family and formalcaregivers, plus stakeholder organisations. The European Horizon 2020 project INdependent LIving support Functions forthe Elderly (IN LIFE) set out to integrate 17 technologies into a single digital platform for older people living with cognitive impairment plus their families, care providers and stakeholders. The IN LIFE evaluation took place across six nationalpilot sites to examine a number of variables including impact on the users, user acceptance of the individual services andthe overall platform, plus the economic case for the IN LIFE platform. The results confrmed the interest and need amongolder adults, family caregivers, formal caregivers and stakeholders, for information and communications technology (ICT).Relative to the baseline, quality of life improved and cognition stabilised; however, there was an overall reluctance to payfor the platform. The fndings provide insights into existing barriers and challenges for adoption of ICT for older peopleliving with cognitive impairment.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Interaction techniques for interactive television (iTV) are currently complex and difficult to use for a wide-range of viewers. Few previous studies have dealt with the potential benefits of multimodal dialogue interaction in the context of iTV for the purpose of flexibility, usability, efficiency, and accessibility. This paper investigates the benefits of introducing speech and connected dialogue for iTV interaction, and presents a case study in which a prototype system was built allowing users to navigate the information space and control the operation of the TV by a speech-based natural language interface. The system was evaluated by analysing the user experience in five categories capturing essential aspects of iTV interaction: interaction style, information load, data access, effectiveness and initiative. Design considerations relevant for speech and dialogue information systems for TV interfaces also emerged from the analysis.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study was to identify and synthesize measures for accessibility to electronic communication for people with cognitive disabilities by seeking answers to the following research questions: What measures to make electronic communication accessible to people with cognitive disabilities are evaluated and reported in the scientific literature? What documented effects do these measures have? Empirical studies describing and assessing cognitive accessibility measures were identified by searches of 13 databases. Data were extracted and methodological quality was assessed. Findings were analyzed and recommendations for practice and research were made. Twenty-nine articles with considerable variations in studied accessibility measures, diagnoses, methods, outcome measures, and quality were included. They address the use of Internet, e-mail, telephone, chat, television, multimedia interfaces, texts and pictures, operation of equipment, and entering of information. Although thin, the current evidence base indicates that the accessibility needs, requirements, and preferences of people with cognitive disabilities are diverse. This ought to be reflected in accessibility guidelines and standards. Studies to systematically develop and recommend effective accessibility measures are needed to address current knowledge gaps.

Tidskriftsartikel (refereegranskat)abstract
- The purpose is to suggest guidelines for supporting the transfer of design and evaluation methods from one organization/field/sector to another. There exist a variety of methods for designing and evaluating interactive socio-technical systems. Many of them have been developed for dedicated purposes, such as heuristic evaluation, referring to specific situations and artifacts. Due to the recent diversification of devices and the continuing diffusion of society with interactive systems, applying design and evaluation methods in an effective and efficient way has become crucial, in particular when operating under tight economic conditions and demanding user constraints. Learning from other projects, cases, disciplines or sectors seems to be one way to effectively apply methods in design and evaluation. In order to validate the suggested guidelines, the guidelines are theoretically informed and empirically supported by the use of a case study. The results consist of a set of seven guidelines for method transfer. The guidelines are described in terms of questions to ask, expected input and expected output and how they relate to the other guidelines. Transferring methods require an informed procedure, reflecting the rationale of methods, application-specific factors and experience of use. In this paper, some conceptual foundations are given when exploring transferability of methods and implemented in the field of IT cross-sector developments. The developed guidelines allow developers to identify situation-specific elements and design an effective learning experience for a case at hand. The introduced content structure and interactive features show an effective way of developer support.

- The purpose of the study is to explore when and how technology becomes a topic in interactions involving people with dementia and their carers. Three dyads of older women with dementia and their carers participated in the study. The dyads interacted in the home environments of the persons with dementia using tablet computers and two web-based applications with generic pictures, videos, and music files (CIRCA) and personalized pictures and films (CIRCUS). The data included twenty-one video-recorded interactions. Topical episode analysis and transcripts of interaction were used to analyze and exemplify when and how technology was talked about in the dyads. The dyads were engaged in exploring the tablets, and six common ways of making technology a topic of conversation were identified: talk about tech problems, commenting actions, expressing uncertainty in navigation, instructing and explaining, expressing surprise, and talk about technical development. The dyads explored the tablets in ways that were reflected in the content of their conversations. If people with dementia and their carers should benefit from todays technology, such as there is evidence for the interactions examined in this study, their homes and daily environments must be equipped with sufficient internet access and technical support.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this paper is to describe the need of a method by which we can estimate the return on accessibility investments in information technology (IT) systems. This paper reveals some of the reasons why accessibility still is a secondhand criterion when designing digital services. It also describes the authors experiences regarding the concept of accessibility and how it must develop in order to obtain the status of a basic business criterion for the benefit of disabled people who are currently excluded from public services and labour markets. The paper also questions the need of a separate accessibility standard. Additionally, we discuss some of the hindering in the market and limiting perspectives that are blocking further development. One of the problems in the market seems to be that accessibility as a concept has been more of an issue about creating equal opportunities and therefore probably does not have the quality of a business criterion. In order to bridge that gap, we argue for replacing accessibility with reachability, which is a concept based on a measure used by media when estimating the reached percentage of a population or target group.
