“…Ένας πολλά υποσχόμενος τομέας των συστημάτων ARA σχετίζεται με παρεμβάσεις ειδικής αγωγής κατάλληλες για μαθητές με προβλήματα όρασης ή τύφλωση. Εκτός από τα προφανή οφέλη για τους ίδιους τους τυφλούς μαθητές όπως η ενίσχυση της χωρικής γνώσης, της μνήμης, της προσοχής, της εμπλοκής, των κινήτρων, της πλοήγησης, της εμπιστοσύνης, της εμβύθισης και της αλληλεπίδρασης, οι εφαρμογές ARA ενισχύουν την αποδοχή και τη συνεργασία μεταξύ των συνομηλίκων (Giannakopoulos et al, 2018).…”

Η εκπαίδευση των μαθητών με ειδικές εκπαιδευτικές ανάγκες παρουσιάζει ιδιαίτερο ενδιαφέρον, διότι παρόλο που οι μαθητές μπορεί να εμφανίζουν κοινά χαρακτηριστικά σύμφωνα με τη διάγνωσή τους, εντούτοις απαιτεί προσωποποιημένες προσεγγίσεις μάθησης. Η προσωποποιημένη μάθηση είναι μια καινοτόμος τάση σε πολλά εκπαιδευτικά περιβάλλοντα, όπως είναι και τα περιβάλλοντα συνεκπαίδευσης, η οποία προϋποθέτει την προσαρμογή των μεθόδων διδασκαλίας. Οι μέθοδοι αυτές πληρούν τις απαιτήσεις της παιδαγωγικής του 21ου αιώνα, της διαφοροποιημένης παιδαγωγικής και των αρχών του καθολικού σχεδιασμού για τη μάθηση. Για το βέλτιστο αποτέλεσμα μιας σύγχρονης παιδαγωγικής προσέγγισης είναι απαραίτητη η αξιοποίηση της σύγχρονης τεχνολογίας, με προσιτό εξοπλισμό, όπως είναι τα tablets και τα smartphones, και εύκολες στη χρήση εφαρμογές, οι οποίες μπορούν να υποστηρίξουν εκπαιδευτικούς και μαθητές οπουδήποτε και οποτεδήποτε. Με δεδομένο ότι οι εκπαιδευτικοί θεωρούνται ο μοχλός κάθε εκπαιδευτικής καινοτομίας, λαμβάνονται υπόψη οι απόψεις τους αναφορικά με τα εμπόδια για την εισαγωγή ψηφιακών μαθησιακών εργαλείων στην τάξη, όπως είναι η έλλειψη κατάρτισης, εξοπλισμού και εκπαιδευτικού υλικού. Υπό αυτό το πρίσμα, η συγγραφική ομάδα στο παρόν άρθρο παρουσιάζει πρακτικές σχεδιασμού και ανάπτυξης εφαρμογών βασισμένες στην τεχνολογία αιχμής, όπως είναι η επαυξημένη πραγματικότητα, που σε συνδυασμό με τα παραδοσιακά puzzles και τις τεχνικές της παιχνιδοποίησης ορίζουν το πεδίο της διαμεσικής μάθησης.

“…Connectivity facilitated by the Internet has resulted in multiplayer interaction modes like in the case of Memor-I Studio, an open-source platform allowing the creation of AG with online player vs. player capability [22]. Particularly in the last decade, mobile smartphones, a massively accepted technological medium, have become the incubator of various successful AGs, such as "Papa Sangre", a horror-themed adventure game based on binaural audio [23], "Audio Game Hub", a collection of accessible arcade games [24], and "Bloom", an interactive environment for artistic musical experimentations [25].…”

Augmented Reality Audio Games (ARAG) enrich the physical world with virtual sounds to express their content and mechanics. Existing ARAG implementations have focused on exploring the surroundings and navigating to virtual sound sources as the main mode of interaction. This paper suggests that gestural activity with a handheld device can realize complex modes of sonic interaction in the augmented environment, resulting in an enhanced immersive game experience. The ARAG “Audio Legends” was designed and tested to evaluate the usability and immersion of a system featuring an exploration phase based on auditory navigation, as well as an action phase, in which players aim at virtual sonic targets and wave the device to hit them or hold the device to block them. The results of the experiment provide evidence that players are easily accustomed to auditory navigation and that gestural sonic interaction is perceived as difficult, yet this does not affect negatively the system’s usability and players’ immersion. Findings also include indications that elements, such as sound design, the synchronization of sound and gesture, the fidelity of audio augmentation, and environmental conditions, also affect significantly the game experience, whereas background factors, such as age, sex, and game or music experience, do not have any critical impact.

“…However, with the fast development of the graphical operating systems the video games started to dominate due to strong market demand. Recently, however, the audio games have grown in popularity (Merilampi, Koivisto, & Sirkka, 2018) and have evolved into an important type of computer games devoted not only to the blind users (Giannakopoulos, Tatlas, Giannakopoulos, Floros, & Katsoulis, 2018).…”

The paper presents an application for interactive sonification of images intended for use on mobile devices in education of blind children at elementary school level. The paper proposes novel sonification algorithms for converting colour and grayscale images into sound. The blind user can interactively explore image content through multi‐touch gestures and select image sub‐regions for sonification with real‐time control of the synthesized sound parameters such as amplitude, frequency and timbre. Additionally, images may contain text fields read by text‐to‐speech synthesizer. The usability of one of the proposed sonification schemes is tested by collecting data on the tracking accuracy and recognition speed of basic shapes, such as lines, curves, as well as figures and simple functions. In order to facilitate the learning process for blind children, a number of games were proposed that use the devised sonification schemes. The first game—“Hear the Invisible”—is intended for two players—one child draws a shape and the task of the other one is to guess the displayed shape by means of the available sonification methods. The second proposed game is “Follow the Rabbit” and is intended for a single player who tracks a colourful “Rabbit” that runs along a path representing a given geometric shape. The obtained results show that the proposed sonification methods allow to reach previously unattainable levels of flexibility in exploration of shapes and colours. The main application of the described interactive tool is to teach geometry and mathematics in schools for blind children. The developed games are meant to enhance the learning process and motivate the children. What is known about the topic Sonification is a generic term for data‐based non‐speech sound generation. Interactive sonification is a relatively fresh area of study, where the listener heavily influences the process of sound synthesis. Earlier studies on sonification and educational computer games have shown that it is possible to demonstrate shapes such as plots and geometry using only non‐verbal sounds. What the paper adds The paper proposes an interactive sonification algorithm that can be used on greyscale or colour images using additive synthesis and the HSV colour representation. The presented software also allows to record and analyse user interaction with the images, making it a good research tool for current and future sonification algorithms. The paper presents a pilot study with blind children using two games that improve the learning process of the proposed algorithms. Implications for practice and/or policy Once the software is openly released it can be easily installed on any Android OS device to allow blind users to analyse images by touch. The proposed games train the users the basics of the sonification algorithm in a competitive context. The software can be especially useful in education of blind children, eg, in teaching geometry, math and in training visual and spatial imagination.
