A Mobile Agent Approach for Ubiquitous and Personalized eHealth Information Systems

1. A Mobile Agent Approach for Ubiquitous and Personalized eHealth Information Systems Panagiotis Germanakos1, Constantinos Mourlas1, George Samaras2 1Faculty of Communication & Media Studies, National & Kapodistrian University of Athens {pgerman, mourlas}@media.uoa.gr http://www.media.uoa.gr/~pgerman 2Computer Science Department, University of Cyprus cssamara@cs.ucy.ac.cy The Mobile Paradigms Emergence In the face of the existing systems and platforms diversity and information sparsity, mobile agent technologies can provide the base for ubiquitous, transparent, secure, interoperable, and integrated eHealth information systems for the provision of adapted and personalized sustainable services to the citizens. Challenges in the Design of Adaptive and Personalized eHealth Architectures • Primary considerations for quality on demand services: • Getting “anytime, anywhere and anyhow” • Flexibility • Accessibility • Context-awareness • Personalized eHealth services • Security • User interfaces characteristics: • Friendlier • Enabling active involvement (information acquisition) • Giving control to the citizen • Provide easier means of navigation supported by the small screens of the mobile devices • Enable adaptation of hypermedia, multi-media, and multi-modal intelligent and personalized user interfaces

2. Web Personalization – the “New” User Profiling Imperative Given “Traditional” User Profiling: “Traditional” User Profile Device / Channel Characteristics “Traditional” User Characteristics + But: ?Could the user profiling be considered complete incorporating only these dimensions? ? Do the designers and developers of Web-based applications take into consideration the real users preferences in order to provide them a really personalized Web-based content? ?Many times this is not the case. How can a user profiling be considered complete, and the preferences derived optimized, if it does not contain parameters related to the user perceptual preference characteristics? By User Perceptual Preference Characteristics we mean all the critical factors that influence the visual, mental and emotional processes liable of manipulating the newly information received and building upon prior knowledge, that is different for each user or user group. These characteristics determine the visual attention, cognitive and emotional processing taking place throughout the whole process of accepting an object of perception (stimulus) until the comprehensive response to it. It has to be noted at this point that the user perceptual preference characteristics are directly related to the “traditional” user characteristics, since they are affecting the way a user approaches an object of perception, completing this way the “New” User Profiling introduced.

4. An Agent-based Paradigm Approach Agents are processes with the aim of performing tasks for their users, usually with autonomy, playing the role of personal assistants. • Advantages of the intelligent mobile agents are: • Reduction of the network load • overcoming network latency • asynchronous and autonomous execution • dynamic adaptation Agent-based Adaptation and Personalization Architecture pgerman@media.uoa.gr| pgerman@cs.ucy.ac.cy http://www.media.uoa.gr/~pgerman
