3 1) Introduction 2) Solution Approach 3) Conclusion

4 Current Situation in Mobile Computing Technological Level Geographic positioning technologies become more and more common in mobile devices Mobile connectivity gets cheaper, faster and more reliable Infrastructure for ubiquitous computing is available Application level Demand for mobile services increases Provisioning of mobile services is reserved to professionals Utilization is too complicated for end-users Hiding the Complexity of Location-based Services, Matthias Böhmer 4

5 Complexity of Location-based Services Location-based Service Application, carrying a value to its user Relevant and available at a certain location Complexity Proprietary development work, expert knowledge Effort for download, installation, and configuration Hiding the Complexity Simplifying the life cycle of location-based services Hiding the Complexity of Location-based Services, Matthias Böhmer 5

6 1) Introduction 2) Solution Approach 3) Conclusion

7 Simplification along the Life Cycle of LBS Hiding the Complexity of Location-based Services, Matthias Böhmer 7

8 Widgets for Location-based Services Widgets Concept borrowed from the web Lightweight, self-contained applications User interface and functional logic Widgets as LBS Applications for mobile utilization Contextual binding (location) Semantic binding (tagging) Hiding the Complexity of Location-based Services, Matthias Böhmer 8

9 Authoring Toolkit for User-driven Provision Requirements Useable for the common internet user No need for specialized knowledge Easy and intuitive development environment Building blocks for user interface and functional logic Hiding the Complexity of Location-based Services, Matthias Böhmer 9

10 Authoring Toolkit for User-driven Provision Hiding the Complexity of Location-based Services, Matthias Böhmer 10

11 Context-aware Utilization Filtering by Location Low-level context Spatial relevance Problem of choice overload Profile-based Filtering High-level context Semantic relevance Tag based Hiding the Complexity of Location-based Services, Matthias Böhmer 11

12 Context-aware Utilization Hiding the Complexity of Location-based Services, Matthias Böhmer 12

13 1) Introduction 2) Solution Approach 3) Conclusion

14 Use Cases and Scenarios Examples Location-based surveys (text, media, survey form) Mobile avatar (contact form, news feed, guest book) Advertising Possibilities Combination of existing building blocks Modifying existing widgets Hiding the Complexity of Location-based Services, Matthias Böhmer 14

15 Current Results and Future Work Current Results User-generated location-based services Location-aware and personalized mobile user interface LBS 2.0 Future Work More functionality and building blocks for widgets Delve deeper into context-awareness User study and evaluation Using web technologies on mobile phones Hiding the Complexity of Location-based Services, Matthias Böhmer 15
