Informal learning allows learners to be in charge of their own learning process instead of being a content consumer. Harnessing mobile technology in informal learning field could help learners in taking a learning opportunity whenever they need either individually or in a group. This paper presents a small-scale study to investigate how people may use mobile technology for learning purposes in cultural heritage contexts. A focus group approach was used to capture preliminary results of user requirements. Based on these results, a scenario-based method was used to reflect a tangible picture regarding how people interact with mobile services. This study serves as an initial step of the series of gathering user requirements in developing a mobile location-based learning service. [For the full proceedings, see ED562093.]
