Technological Level
Geographic positioning technologies becomemore 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
Current Situation in Mobile Computing
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

1) Introduction
2) Solution Approach
3) Conclusion
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
