Indoor wayfinding has captured the attention of location-based services researchers due to differences in the features of orientation and location between indoor and outdoor spaces. The recognition of indoor landmarks serves a vital role for pedestrian navigation to destinations. To provide better indoor path planning and path guidance, this paper proposes a landmark-based Attractiveness Strength Grid (ASG) model that caters to a wide spectrum of individualized wayfinding services. By adapting techniques for the measurement of salience from outdoor landmarks, indoor landmarks can be measured using a series of quantitative characteristics that are grouped into three aspects: visual aspects, semantic aspects and structural aspects. In the ASG model, each grid cell that is embedded with these salient characteristics can be oriented to surrounding landmarks to ensure the use of the ASG model to plan various paths, such as the most reliable path, the path with the most identifiable landmarks or specific patrol paths for individuals. Using a large shopping mall as a test site, the model is validated by two scenarios that illustrate the diverse applications of the ASG model in the field of indoor wayfinding.
