Autonomous players

  • Autonomous players

  • Intensive communication task

  • No centralization

  • Open environment: new players / players leaving without global impact

  • Peripherics

    • Personal assistants
    • Sensors (wearable and fixed)


Each player is an agent

  • Each player is an agent

  • Compliance with pervasive systems

    • Autonomy
    • Intensive communication
  • Agents have two components (Agent Oriented Abstraction):

    • Knowledge: concept classes, instance, actions (that can be further specialized). = Ontology.
    • A decision mechanism (associated to utility function): for instance Evaluate a message, Send an Inform, …


Agents are provided with a layer for acting within knowledge communities

  • Agents are provided with a layer for acting within knowledge communities

  • Knowledge community:

    • a leader + a topic
    • dynamic, no concrete existence, extends the topic
    • Related actions: create, join, inform, request, leave..
  • Exchanges are based on contents

  • Example

    • A: creates a community on concept “Metro station name”
    • B: decides to join the community and informs about “Ginza”, instance of “Metro station name”


In our approach

  • In our approach

  • User-oriented peripherics are associated to Personal Agents

  • Sensor are associated to Context Agents

  • Communications occurs within Virtual Knowledge Communities





Sensor: foot pressure

  • Sensor: foot pressure

  • Context agent produces knowledge: user’s activity level

  • Environmental signal delivery into a metro station

  • Context agent delivers knowledge: station name

  • Personal assistant of traveler : Personal agent

    • knows the desired station and a evaluation rule when to wake-up the traveler (activity is low and desired station is reached)
    • is interested in “Activity level” and “Metro station names”


Wake up the user if necessary

  • Wake up the user if necessary



Application design is made easier

  • Application design is made easier

    • Agents are made independently
  • New applications appears with new contents

  • System is open-ended and compliant with pervasive systems
