Service Fusion is an interactive 3D User Interface (UI) which allows different real-time services to cooperate in order to complete a user task on a mobile device. The UI is based on objectifying data and describing it in an ontological language and combining this with behavioural scripts. The 3D UI is used to visualize the different data and services, while providing means for object selection and manipulation. Two use cases, a cinema and a music service have been implemented. Service Fusion paradigm has been implemented into a touch screen device context with three different 3D scenes: 3D Map (City of Oulu), 3D Music Club and 3D Office. Also, AR version of the Service Fusion has been developed for mobile phone context.
