Introduction

• Graphical User Interfaces (GUI)
• GUIs may include complex/diverse types of
  interaction between components as well as to
  external distributed heterogeneous resources.
• Negotiation, cooperation and competition may
  occur among different entities.
• Some aspects of a GUI can have autonomous
  characteristics.
• A modification or expansion of the system can be
  anticipated.

Introduction
Software Agents
Hayes-Roth Intelligent agents continuously
perform three functions perception of dynamic
conditions in the environment, action to
affect conditions in the environment and
reasoning to interpret perceptions, solve
problems, draw inferences, and determine actions.
8
Introduction

• Software Agent System
• Development
• Gaia
• SODA
• JADE

Development of Agent-Based GUI
10
Development of Agent-Based GUI
Identification of goals and sub-goals

• Examples of goals
• exercises
• information
• experimentation
• etc.

11
Development of Agent-Based GUI
Identification of functional requirements and
sub-functions

• Examples of functions
• answering of questions
• choosing the appropriate
• result
• login/logout
• etc.

12
Development of Agent-Based GUI
Extended by external connections

• Integration of external objects
• Encapsulation of safety critical objects and
  access
• Encapsulation of objects relevant for several
• optimization approaches
• Easy update of access
• Parallel existence of accessing objects
• Reduced network load by caching

13
Development of Agent-Based GUI
Post refinement activities

• Node-Based Definition
• Agent identifier
• Role-based access
• Related ontologies
• Description

• Edges/interaction acts
• Message parameters of the FIPA ACL Message
  Structure
• Specification of the Foundation for Intelligent
  Physical
• Agents (FIPA), e.g. type of communicative act,
  participants,
• content
• Communication act identifier
• Conditions
• Related ontologies
• Parameters

• Technologies
• JSP
• Ajax
• Echo Web Framework
• JADE

14
Development of Agent-Based GUI

• Advantages of agent-based interfaces
• Similarity of goal the hierarchy intended by the
  problem definition
• Definition of optional and required nodes/agents
  and edges/communication acts
• Extension of the system during runtime
• Failure tolerance
• Performance control of the components
• Pro-activity is directly available for
  interfaces

Conclusions and outlook

• We presented several stages of specification and
  design and supposed usage of several strategies
  like creative techniques and design patterns for
  innovative and complete architectures.
• To examine the usefulness auf our approach we
  designed the ABEL-GUI, an agent-based interface
  for the e-learning domain.
• Actually we implement this developed interface as
  a framework which we plan to populate with
  several specialised agents.
