Involving users has become a prerequisite these days in ITproduct and service development processes; hence, the question is not so much about why we should involve users, but rather how they should be involved. Embracing a Living Lab approach means to strive to involve users throughout the innovation process and to make users engaged co-creators of the innovation. In this paper, we present different degrees of user involvement in design and evaluation processes and relate these to our experiences of involving users in Mobile Living Lab situations. We identify aspects we have grappled with in these process and issues that needs to be elaborated on further since the area of Mobile Living Lab is growing and concepts such as ubiquitous computing and context awareness is emerging. This in turn, sets new demands on methods for user involvement in the wild.
