    The recent profusion of smartphones in the mobile industry offers new opportunities for mobile services vendors. One of the most influenced service categories is location-based services (LBS). Based on insights from behavioural decision-making, a theoretical framework is developed to analyse individuals' decisions to use LBS. We focus on the cognitive processes involved in individual decision-making. Our research is based on two studies. First, we investigated the use of LBS through semi-structured interviews of smartphone users. Second, we explored daily LBS use through a study based on diaries. The findings highlight the distinct value dimension in specific contexts of use and the positive experiences of the service as the main drivers of LBS use. Thus, the user decision to use LBS can be described by either a comparative mode based on the value of LBS in relation to other available options, or by an intuitive mode where past experiences trigger the use of heuristics. These modes in turn underscore the positive influences on the continuance of LBS use.

    The continuance of use is an important topic of IS research. However, in the past, many researchers have focused on adoption rather than IS continuance. Studying continuance is of equal importance, because if use does not persist, this may limit the revenues of the provider. This is particularly true for consumer-oriented services, which rely on advertising, or subscription-based revenue models. In this paper, we investigate the determinants of location-based services (LBS) continuance as a relevant case study for the examination of IS continuance generally. A research model is developed and empirically tested through a survey of a representative sample in Germany. The proposed model builds on and extends the Limayem et al. model of IS continuance. Our analysis highlights the importance of habit and emotion in LBS continuance. The results indicate that habit has a stronger predictive power than continuance intentions for LBS continuance and that emotions are an important driver for user satisfaction with LBS.

    Exploring use patterns and perceived value of location-based services

    The recent impressive diffusion of smartphones in the mobile industry offers new opportunities to mobile services vendors. One of the most influenced service categories are location-based services. In the present study we investigate the use of location-based services. Based on insights from behavioural decision making a theoretical framework is developed to analyse the individual decision to use location-based services and to identify the factors influencing use. Through a qualitative study based on LBS users' interviews, we find that the distinct value dimension and the positive experiences from the service use are the main drivers, pivotal to the continuance of use.
