Location based System for mobile GSM devices Using

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

Overview

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

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

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

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

Articles ►Context-Aware Communication ►Wearable Computing Meets Ubiquitous Computing

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

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

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

Context-Aware Communication ► Improving relevance ► Minimizing disruption ► Improving awareness ► Reducing overload ► Selecting channels

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

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 workgroup 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
