Human-Computer Interaction and games set a new domain in understanding people’s motivations in gaming, behavioral implications of game play, game adaptation to player preferences and needs for increased engaging experiences in the context of HCI serious games. When the latter relate with people’s health status, they can become a part of their daily life as assistive health status monitoring/enhancement systems. Co-designing HCI-SGs can be seen as a combination of art and science that involves a meticulous collaborative process. The design elements (...) in assistive HCI-SGs for Parkinson’s Disease patients, in particular, are explored in the present work. Within this context, the Game-Based Learning design framework is adopted here and its main game-design parameters are explored for the Exergames, Dietarygames, Emotional games, Handwriting games, and Voice games design, drawn from the PD-related i-PROGNOSIS Personalized Game Suite holistic approach. Two main data sources were involved in the study. In particular, the first one includes qualitative data from semi-structured interviews, involving 10 PD patients and four clinicians in the co-creation process of the game design, whereas the second one relates with data from an online questionnaire addressed by 104 participants spanning the whole related spectrum, i.e., PD patients, physicians, software/game developers. Linear regression analysis was employed to identify an adapted GBL framework with the most significant game-design parameters, which efficiently predict the transferability of the PGS beneficial effect to real-life, addressing functional PD symptoms. The findings of this work can assist HCI-SG designers for designing PD-related HCI-SGs, as the most significant game-design factors were identified, in terms of adding value to the role of HCI-SGs in increasing PD patients’ quality of life, optimizing the interaction with personalized HCI-SGs and, hence, fostering a collaborative human-computer symbiosis.

Decision making in noisy and changing environments requires a fine balance between exploiting knowledge about good courses of action and exploring the environment in order to improve upon this knowledge. We present an experiment on a restless bandit task in which participants made repeated choices between options for which the average rewards changed over time. Comparing a number of computational models of participants’ behavior in this task, we find evidence that a substantial number of them balanced exploration and exploitation by (...) considering the probability that an option offers the maximum reward out of all the available options.

The aim of this paper is to introduce the concept of the mirror as a methodological tool, with which Plato discusses reflection and describes the mimetic phenomena. The notion of the mirror first presents Plato’s view on the metaphysical division of the world. It then accounts for Plato’s hostility towards the poets and reveals that the ideal polis is the product of a special kind of philosophical mimesis. I argue that Plato’s own mirror is the dialogues he writes, and the (...) perfection of his mimetic activity is juxtaposed to the hazardous imitations of the poets. (shrink)

The present study proposes a new reconstruction and a new interpretation of a quite singular piece of sculpture with relief decoration, discovered on Melos at the beginning of the last century. It belongs to the permanent collection of Roman sculpture of the National Archaeological Museum of Athens. After a detailed presentation and iconographical analysis of its relief decoration, we proceed to a new interpretation of its function, always in connection with the social, historical and artistic context of the Cyclades in (...) Late Antiquity. (shrink)

In 2009 during excavations at the courtyard of the late eleventh-/early twelfth-century CE church of Aghios Ioannis Theologhos at the site of Palio Ligourio, the first incubation relief from the Asklepieion of Epidauros was unearthed (Epidauros Museum inv. no. 1305). The relief, dated to the beginning of the fourth century and, probably, imported from Athens, depicts an incubation scene and the associated dream. Asklepios and his wife, Epione, preside over their sons, Machaon and Podaleirios, conveying the power of healing to (...) an ailing man, reclining on a stibas, until now not documented otherwise in the sanctuary of Epidauros.

Τhis paper revisits the luxurious Palaiologan illuminated manuscript of the New Testament, Codex 31 of the Hagia Lavra monastery in Kalavryta. Iconographic and stylistic characteristics of the miniatures are compared with others and with seals of the early fifteenth century, as well as with the wall-paintings of the Pantanassa Monastery at Μystras (ca 1430). It is argued that the codex was commissioned by Georgios Kantakouzenos Palaiologos, a close collaborator of Konstantinos Palaiologos, Despot of the Morea and subsequent emperor, who lived (...) in Kalavryta and promoted his personal library, which was enjoyed even by Ciriaco of Ancona.

Wonder is undoubtedly a term that floats around in today’s academic discussion both on ancient philosophy and on philosophy of education. Back in the 4th century B.C., Aristotle underlined the fact that philosophy begins in wonder, without being very specific about the conditions and the effects of its emergence. He focused a great deal on children’s education, emphasizing its fundamental role in human beings’ moral fulfillment, though he never provided a systematic account of children’s moral status. The aim of this (...) paper is to examine, on the one hand, if, to what extent, and under what conditions, Aristotle allows for philosophical wonder to emerge in children’s souls, and, on the other hand, how his approach to education may shed light to the link between wonder and the ultimate moral end, i.e. human flourishing. We will, thus, 1) try to offer a unified outlook of the philosopher’s views on children’s special cognitive and moral state, and 2) illustrate how wonder contributes in overcoming their imperfect state of being.

Today humanity is in the midst of the massive expansion of new and fundamental technology, represented by advanced artificial intelligence (AI) systems. The ongoing revolution of these technologies and their profound impact across various sectors, has triggered discussions about the characteristics and values that should guide their use and development in a responsible manner. In this paper, we conduct a systematic literature review with the aim of pointing out existing challenges and required principles in AI-based systems in different industries. We (...) discuss our findings and provide general recommendations to be considered during AI deployment in production. The results have shown many gaps and concerns towards responsible AI and integration of complex AI models in the industry that the research community could address. (shrink)
