This research examined the adoption of indoor location-based services in Norway. By expanding the Technology Acceptance Model (TAM), a research model, known as the mobile services acceptance model, was used. Based on the research model, seven research hypotheses were presented. The proposed research model and hypotheses were empirically tested using data collected from a survey of users of an indoor location-based service, finding reading rooms, at a Norwegian university. Support was found for five of the seven research hypotheses. Among the factors, the perceived usefulness has the strongest influence on the intention to use. The finding also indicated that trust did not have a direct positive effect on intention to use.
