Abstract: This paper summarizes experiences of empirical research done for evaluating information <strong>and</strong><br />

communication technology (ICT) based services that aim at supporting older users in independent living. Over<br />

the course of four years, we have explored several different ICT based service concepts in field trials. The goal of<br />

the field trials has been to expose novel ICT based service concepts to everyday life of ageing users through<br />

adoption of services in real life use. As a result, rich data about user experience <strong>and</strong> value of the service for<br />

different stakeholders has been collected <strong>and</strong> analyzed. Conducting the field trials has exposed practical issues<br />

about how to conduct research with older users. In this paper the experiences are summarized. The findings<br />

show that older participants differ from other user groups in several ways. Researchers faced challenges with<br />

research procedures during the field trials. These challenges were sometimes caused by exploratory nature <strong>and</strong><br />

limited duration of the field trial; the participants of field trials always did not want to invest on adopting the<br />

services as their everyday routines, but instead restricted the use into testing technology <strong>and</strong> related service as<br />

isolated objects from their everyday lives. Often, this also led into situations where participants judged the value<br />

of the service to “someone else”, <strong>and</strong> were not willing to adopt it themselves.<br />

1. Introduction<br />

The ongoing change in demographics in Europe has triggered interest towards exploring the potential<br />

of information <strong>and</strong> communication technology (ICT) based services in supporting ageing population in<br />

independent living. ICT based services have been emerging into support everyday life, such as<br />

banking, shopping or information services. However, their adoption has been limited with older users.<br />

For example, only 28% of European older users aged from 55 to 74 uses Internet frequently (Eurostat<br />

2010). Older users are not <strong>using</strong> online banking services (Pew research, 2010) as frequently as the<br />

younger users. Sayago <strong>and</strong> Blat (2009) found out that the technology itself, users’ computer<br />

experience <strong>and</strong> educational level do not have influence on the accessibility of the web services for<br />

older users. Instead, the users had difficulties to remember task-related steps, underst<strong>and</strong>ing<br />

technical words <strong>and</strong> <strong>using</strong> the mouse. Vastenburg et al. (2008) identified in their work barriers that<br />

hinder the technology adoption by older users, including complexity <strong>and</strong> learnability, lack of perceived<br />

benefit, <strong>and</strong> compatibility issues. Usability <strong>and</strong> accessibility are issues that have been extensively<br />

studied during last couple of decades, <strong>and</strong> user interface solutions that are usable <strong>and</strong> accessible<br />

also for older users can be designed <strong>using</strong> human-centred design practises (Newell et al. 2006).<br />

Perhaps more often, the obstacles for adopting ICT based services are in older users’ attitudes <strong>and</strong><br />

feelings. According to Eisma et al. (2004) negative attitudes of older users are caused by the popular<br />

perception of age <strong>and</strong> technology, lack of awareness of technology, the feeling that technology is not<br />

useful for older people <strong>and</strong> the feeling that it is too difficult to use. Thus, it is important to involve older<br />

users in design <strong>and</strong> evaluation phases of technology concepts. Field trials can be used to expose<br />

novel ICT based service concepts to everyday life of aging users through adoption of services in real<br />

life use. Faber <strong>and</strong> de Vos (2008) state that it is a suitable method for gathering underst<strong>and</strong>ing how<br />

people use the service or application in real-life situations, what are the practical impacts of the<br />

service in the lives of the users, how it should be improved <strong>and</strong> what is its market value (Faber <strong>and</strong> de<br />

Vos, 2008). Field trial is a method of qualitative case research strategy (Benbasat et al. 1987), which<br />

is often used in studying ICT products or services.<br />

In this paper, experiences from empirical research done for evaluating ICT based services for older<br />

users are summarized. The experiences have arisen over the course of four years from the research<br />

work of observing <strong>and</strong> interviewing older people, <strong>and</strong> planning <strong>and</strong> supervising the research work<br />

itself. For the purpose of this paper, we analyzed the experiences of six researchers who had been<br />

involved in six different case studies.<br />
