Location based System for mobile GSM devices

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 APIs
• 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

Context-Aware Communication

• How the changing information about an
  individuals location, environment and social
  situation can be used to initiate and facilitate
  peoples 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 peoples interactions with each other and
  their environment
• Applications that apply knowledge of peoples
  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

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.

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
