With the latest development of wireless networks and high performance handheld devices, web applications are no longer bounded within the desktop platforms. Many services targeting individual users are already running on diverse mobile devices. Mobile interfaces for hypermedia GIS services are some of the prominent applications for social networks and their development poses great challenges. In this paper we present the mobile interfaces which systematically link database technologies, Geographical Information Systems, and hypermedia information services on mobile devices. The user-oriented design concept is used to design and implement the mobile interfaces as to ensure their usability and user-friendliness. These mobile interfaces support cultural heritage communities to collect, create, share and search location-based hypermedia on wireless networks. At the same time, mobile usability issues are explored in-depth.
