Chapter 24 DOI: 10.4018/978-1-4666-8468-3.ch024 A Guide to Online Applications for User Involvement in Living Lab Innovation ABSTRACT The use of Living Labs is gaining importance as an approach to involve users in innovation and develop- ment, serving to make users active participants in the development of the networked society. However, Living Labs are currently not taking full advantage of online applications to support user involvement, even though such applications are gaining impact in other felds of innovation. The purpose of this chapter is to: (i) present a framework to classify and relate online applications for user involvement to the Living Lab context and (ii) present a set of guidelines for the usage of such applications within Living Labs. The framework and the guidelines are the results of a collaborative process involving seven Living Lab researchers from four Nordic Living Labs and are meant to guide Living Lab administrators on whether or how to use online applications for user involvement. The framework and the guidelines might also be useful for the designers of online applications. INTRODUCTION The use of Living Labs is a relatively new ap- proach to the involvement of users in innovation and development processes (Schumacher & Niitamo, 2008). In the field of ICT development, Living Labs have been defined as environments for innovation and development in which users are exposed to new ICT solutions in (semi)-realistic contexts as part of medium- or long-term studies (Følstad, 2008a). Consequently, Living Labs are of high relevance to innovation and development in the networked society. The Living Lab ap- proach has received much interest over the last few years. This is particularly seen in the growth of the European Network of Living Labs (http:// www.openlivinglabs.eu/), which now contains more than two hundred Living Labs across Europe.
