People with Intellectual Disability (ID) encounter several problems in their daily living regarding their needs, activities, interrelationships, and communication. In this paper, an interactive platform is proposed, aiming to provide personalized recommendations for information and entertainment, including creative and educational activities, tailored to the special user needs of this population. Furthermore, the proposed platform integrates capabilities for the automatic recognition of health-related emergencies, such as fever, oxygen saturation decline, and tachycardia, as well as location tracking and detection of wandering behavior based on smartwatch/smartphone sensors, while providing appropriate notifications to caregivers and automated assistance to people with ID through voice instructions and interaction with a virtual assistant. A short-scale pilot study has been carried out, where a group of end-users participated in the testing of the integrated platform, verifying its effectiveness concerning the recommended services. The experimental results indicate the potential value of the proposed system in providing routine health measurements, identifying and managing emergency cases, and supporting a creative and qualitative daily life for people with disabilities.

Παρουσίαση του QuaLiSID στο συνέδριο Kleefstra Syndrome Scientific Conference 2023
Σύντομη περιγραφή
Το Kleefstra Syndrome Scientific Conference 2023 έλαβε χώρα στη Λουμπλιάνα της Σλοβενίας στις 1 και 2 Ιουνίου 2023. Το συνέδριο αυτό εστιάζει στο σύνδρομο Kleefstra, μια σπάνια γενετική διαταραχή που οδηγεί σε διαφόρων βαθμών αναπτυξιακές δυσκολίες και νοητική αναπηρία. Η εκδήλωση φέρνει κοντά ερευνητές του συνδρόμου Kleefstra, κλινικούς γιατρούς και ερευνητές από διαφορετικούς τομείς, όπως η Τεχνητή Νοημοσύνη, που έχουν ως κοινό ενδιαφέρον να μοιραστούν νέα ερευνητικά ευρήματα σχετικά με το σύνδρομο Kleefstra και νέες τεχνολογικές εξελίξεις που μπορούν να οδηγήσουν την κοινότητα Kleefstra, όπως και την ευρύτερη κοινότητα των ατόμων με αναπτυξιακές δυσκολίες και νοητική αναπηρία, στη βελτιστοποίηση της τρέχουσας φροντίδας των επηρεαζόμενων ατόμων.
Η παρουσίαση του QuaLiSID στο συνέδριο, με τίτλο ¨The QuaLiSID system and related video analysis technologies for supporting individuals with intellectual disabilities¨, εστίασε σε δυο κατευθύνσεις: Αφενός μεν στο ολοκληρωμένο σύστημα του QuaLiSID, όπου μετά από μια εισαγωγή συνολικά στις λειτουργίες του συστήματος, εστιάσαμε στις δυνατότητες ενημέρωσης, ψυχαγωγίας και εκπαίδευσης που προσφέρει το σύστημα μέσα από την παροχή συστάσεων πολυμεσικού περιεχομένου βάσει των ενδιαφερόντων του χρήστη. Αφετέρου δε στις δυνατότητες που προσφέρουν οι τεχνολογίες τεχνητής νοημοσύνης που έχουμε αναπτύξει για την ανάλυση πολυμεσικού περιεχομένου (με έμφαση σε εικόνα και βίντεο), οι οποίες όχι μόνο έχουν εφαρμογή στην παροχή συστάσεων αλλά και, με τις απαραίτητες προσαρμογές και επεκτάσεις, πιθανώς μπορούν να συνεισφέρουν και στην ανάπτυξη βελτιωμένων μεθόδων για την ανάλυση ιατρικών δεδομένων.

Σύντομη περιγραφή
In this paper a pure-attention bottom-up approach, called ViGAT, that utilizes an object detector together with a Vision Transformer (ViT) backbone network to derive object and frame features, and a head network to process these features for the task of event recognition and explanation in video, is proposed. The ViGAT head consists of graph attention network (GAT) blocks factorized along the spatial and temporal dimensions in order to capture effectively both local and long-term dependencies between objects or frames. Moreover, using the weighted in-degrees (WiDs) derived from the adjacency matrices at the various GAT blocks, we show that the proposed architecture can identify the most salient objects and frames that explain the decision of the network. A comprehensive evaluation study is performed, demonstrating that the proposed approach provides state-of-the-art results on three large, publicly available video datasets (FCVID, MiniKinetics, ActivityNet).

Περίληψη
In this review paper, we look into how a recommendation system can be adapted to and support people with intellectual disability (ID). We start by reviewing and comparing the main classes of techniques for general-purpose content recommendation. Then, centering on individuals with ID, we collect information on their special needs that may be relevant to or affected by content recommendation tasks. We review the few existing recommendation systems specifically designed or adapted to the needs of this population and finally, based on the reviewed literature sources, we catalog the traits that a future content recommendation system should have in order to respond well to the identified special needs. We hope this listing of desirable traits and future directions in our concluding sections will stimulate research towards opening the doors to the digital world for individuals with ID.

Περίληψη
Complex properties of functional connectivity networks built using source-level neural electromagnetic signals are useful to characterize the alterations of mild cognitive impairment (MCI). Source-level signals were obtained from 20 electroencephalographic and 20 magnetoencephalographic longitudinal recordings of MCI patients using a finite element-based approach with a real-head model of five tissues. Afterwards, a multilayer functional network was built using amplitude-to-amplitude coupling (AAC). Our results showed altered robustness of the AAC network comparing the MCI patients which progress to dementia with the MCI patients which do not progress.

Περίληψη
Epilepsy is one of the most common brain diseases with a major effect in more than 50 million people worldwide. Epilepsy is characterized by frequent recurrent seizures or “ictal” states during which a patient’s neurons become hyperexcitable causing uncontrollable muscular contractions which induce loss of mobility and balance resulting in injury or even death.

Zervakis: A platform for health emergency warning and wandering behaviour detection supporting people with Intellectual Disability, The 15th ACM International Conference on PErvasive Technologies Related to Assistive Environments (PETRA 2022), June 29 – July 01, 2022, Corfu, Greece.
Περίληψη
People with intellectual disabilities (ID) encounter several problems in their daily life, regarding the interaction with their environment, the communication with their caregivers and their mobility. Mobile and modern smartwatch applications have great potential to provide early warning for medical emergencies, such as fever, oxygen saturation decline and, recently, Covid-19 disease. Furthermore, such apps can also track their position, if necessary, and even automatically detect wandering behaviour. In this paper, we propose a platform that will be able to a) automatically recognize health emergency situations and/or detection of wandering behaviour based on smartwatch/smartphone sensors, b) provide appropriate notifications to both user and caregiver when needed. The final system is currently developed within a Greek national research project and a pilot implementation will be evaluated by a Greek assistive center for people with ID.

Περίληψη
People with intellectual disabilities (ID) encounter several problems regarding the interaction with their environment in terms of their daily needs, activities and communication. On this concept, an interactive support system with multiple functionalities is proposed, aiming at optimizing the opportunities provided to people with ID in order to cope with particular everyday issues. Specifically, it will provide information as well as entertainment, including creative and educational activities, through specialized learning programs. Additionally, it will automatically recognize health emergency situations, provide appropriate notifications, feature an emergency call button to contact the responsible caregivers, and support interaction using a specialized voice menu of instructions. The final system will be developed within a Greek research project and a pilot implementation will be evaluated by a Greek association of people with ID. The ultimate goal is to provide an affordable and user-friendly solution, tailored to the users’ needs.
