Can a Virtual Reality Cognitive Training Application Fulfill a Dual Role? Using the Virtual Supermarket Cognitive Training Application as a Screening Tool for Mild Cognitive Impairment
Zygouris, S.; Giakoumis, D.; Votis, K.; Doumpoulakis, S.; Ntovas, K.; Segkouli, S.; Karagiannidis, C.; Tzovaras, D.; Tsolaki, M. (2015)Background: Recent research advocates the potential of virtual reality (VR) applications in assessing cognitive functions highlighting the possibility of using a VR application for mild cognitive impairment (MCI) screening. ... -
Cognitive support embedded in self-regulated e-learning systems for students with special learning needs
Chatzara, K.; Karagiannidis, C.; Stamatis, D. (2014)This paper presents an anthropocentric approach in human - machine interaction in the area of self-regulated e-learning. In an attempt to enhance communication mediated through computers for pedagogical use we propose the ... -
Computers can feel too: Intelligent emotional agents in e-learning systems
Chatzara, K.; Karagiannidis, C.; Stamatis, D. (2010)The introduction of emotional reactions to e-Learning environments might offer a more efficient and effective communication between the user and the machine; a more natural and realistic computer interface. Embodied ... -
An intelligent emotional agent for students with attention deficit disorder
Chatzara, K.; Karagiannidis, C.; Stamatis, D. (2010)We propose the use of an intelligent emotional pedagogical agent to improve the communication channel between the user and the machine for e-learning systems for students with attention deficit disorder. We argue that the ... -
Intuitive user interfaces to help boost adoption of internet-of-things and internet-of-content services for all
Tektonidis, D.; Karagiannidis, C.; Kouroupetroglou, C.; Koumpis, A. (2014)The idea we promote in the chapter is to provide better support to users with disabilities and impairments from the comfort of their home by means of providing them with a set of scalable services which can be either offered ... -
Layered evaluation for data discovery and recommendation systems: An initial set of principles
Manouselis, N.; Karagiannidis, C.; Sampson, D. G. (2014)This paper examines how a layered evaluation framework proposed for adaptive systems (AS) can be applied in the case of recommender systems (RecSys). Our analysis indicates that implementing a layered-based evaluation has ... -
Layered evaluation in recommender systems: A retrospective assessment
Manouselis, N.; Karagiannidis, C.; Sampson, D. G. (2014)Evaluation of recommender systems has only lately started to become more systematic, since the emphasis has long been on the experimental evaluation of algorithmic performance. Recent studies have proposed adopting a layered ... -
Learning assets innovation - Serving the inclusion needs of the socially, intellectually, and physically disadvantaged
Karagiannidis, C.; Decker, B.; Kouroupetroglou, C.; Koumpis, A. (2014)We aim to deploy and validate a novel approach for mainstreaming inclusiveness and accessibility related solutions which can be programmed, distributed and executed in the form of Applications, thus capitalizing on the ... -
Multi-vocality and post-processualism as methodological assets of the 'Collaboration game'
Karagiannidis, C.; Efraimidou, S.; Koumpis, A. (2011)In recent years the gap between educational theory and practice has been closing, but although there have been calls for 'reflexivity', there has been little critical examination of its meanings. Proposed reflexive ... -
Novel Virtual User Models of Mild Cognitive Impairment for Simulating Dementia
Segkouli, S.; Paliokas, I.; Tzovaras, D.; Tsakiris, T.; Tsolaki, M.; Karagiannidis, C. (2015)Virtual user modeling research has attempted to address critical issues of human-computer interaction (HCI) such as usability and utility through a large number of analytic, usability-oriented approaches as cognitive models ... -
Preference-based decision making for personalised access to Learning Resources
Karagiannidis, C.; Lekakos, G.; Vasilakos, A. V. (2008)This article addresses the selection of Learning Resources (LRs; learning material, learning activities, etc.) through a preference-based decision-making framework. We consider the case where a set of LRs are maintained ... -
Social networking to support collaborative interactions in special education
Karagiannidis, C.; Efraimidou, S.; Koumpis, A. (2010)This paper proposes a framework for the collaboration of teachers in special education. The framework builds on, and extends, social networking services, in order to facilitate collaboration amongst the various categories ... -
Special needs at different educational levels: A forecast of 2020
Karagiannidis, C.; Kouroupetroglou, C.; Koumpis, A. (2012)This paper reports on the results of the eAccessibility 2020 study which was funded by the European Commission to explore and analyse the relationships between the emerging Information and Communications Technologies (ICT) ... -
Student's attitude and learning effectiveness of emotional agents
Chatzara, K.; Karagiannidis, C.; Stamatis, D. (2010)This paper describes the development of an emotional agent who affects the attitude of students towards learning and helps them overcome learning obstacles. Face to face communication is simulated through synthetic characters ... -
Synthetic ground truth data generation for automatic trajectory-based ADL detection
Papamakarios, G.; Giakoumis, D.; Votis, K.; Segkouli, S.; Tzovaras, D.; Karagiannidis, C. (2014)In-house automatic activity detection is highly important toward the automatic evaluation of the resident's cognitive state.
