  1. Location based System for mobile GSM devices Using services from the PATS-Lab Program for advanced telecom services

  2. Overview

  3. Objectives • Explore the technology • What have been done in the past • Implement a Location Based system • Look at articles on the subject (context aware, location, mobile) • What are the possibilities

  4. Exploring the technology • How is GSM positioning done • How accurate is it • Pros and contras • How to combine telecom network with ip • Different API’s • Map data • Automatic Call setup based on context

  5. What have been done? • Lots of interesting services have been developed • AMIGOS, Sheep Location, Children Guard, Rental Service, Emergency Alarm…..

  6. Implement a Location based system • Develop a system in Java • Experiment with services • Object tracker, for instance: Locate your lost dog, Get an alarm when your son is down town at 03.00 Saturday night, or not if his older brother is there too • Explore the Parlay (x) API

  7. One simple idea

  8. Context Aware Traffic News Fig: ActorFrame Developers guide, G.Melby

  9. Questions?

  10. Articles • Context-Aware Communication • Wearable Computing Meets Ubiquitous Computing

  11. Context-Aware Communication • How the changing information about an individual’s location,environment andsocial situation can be used to initiate and facilitate people’s interactions with one another. • Autonomy regarding: Context sensing and Communication action • Design issues

  12. Context-Aware Communication • Applications examines and react to a user’ s changing context in order to help promote and mediate people’s interactions with each other and their environment • Applications that apply knowledge of people’s context to reduce communication barriers • Subset of context-aware computing • The line is not always clear

  13. Context-Aware Communication Not obvious that application designers should simultaneously try to maximize autonomy in both dimensions since this removes human common sense. (Tom Erickson: At best awfully hard to implement) Looks at five different applications, organized functionally: Routing, addressing, messaging, providing caller awareness and screening Receptionist assistant and Ether-phone

  14. Context-Aware Communication • Improving relevance • Minimizing disruption • Improving awareness • Reducing overload • Selecting channels

  15. Wearable Computing Meets Ubiquitous Computing • Two different paradigms • Wearable: Problems with localized information, resource control and resource management between multiple people • Ubiquitous: Problems with privacy and personalization • Solution: Peer-to-peer network, mix of the two. HIVE distributed agent architecture

  16. Wearable Computing Meets Ubiquitous Computing Ubiquitous computing in the purest form, all computation is contained in the environment Privacy risk: Potential leak from systems Personalized information: Worst case, every time a person joins a work-group Profile must be added to every device Wearable computing, all computation is handled by the wearable Localized information: Maintaining information Localized control:More CPU power, network demands, needs code to control devices Resource management: Wants more intelligent system than simply allowing the last request

  17. Wearable Computing Meets Ubiquitous Computing • Automatic diary (PR) • Proximate Selection of Big Screen Display (PR,LR) • Theme Music (PR,PE,LR) • DJ (PR,PE,LR,RM) • Remembrance Agent (PR,PE,LI) • Context-aware alert filtering (PR,PE,LI) • “Where’s Brad?” (PR,PE,LR)

  18. Discussion?
