Sistema electrónico de ayuda pedagógica para niños con necesidades educativas especiales utilizando realidad aumentada.

Abstract

Children with special educational needs not associated with disability are children who have difficulty accessing common learning according to their age, accordingly, the curriculum was adapted to the level of competence that develops, including specific resources to improve their teaching-learning process, for this reason, the electronic pedagogical aid system for children with special educational needs using augmented reality, in order to improve the learning of children, interacting with new technologies while assimilating information in a visual and auditory way. The system was developed using the recommendations of the teachers and the psychopedagogues of the educational institution, based on the psychopedagogical report submitted by the District Unit of Support for Inclusion, in which the degree of curricular adaptation is specified, the level of competence according to each academic area, the student's learning style and the strategies to be followed by teachers, parents and psycho-pedagogues. The system is based on the interaction of the child with an augmented reality application performed on an Android device, which shows 3D models and interactive videos related to the subjects of Natural Sciences, this is stimulated when the application recognizes a marker and performs a process of detection and tracing of images, which was developed by the graphical engine of Unity 3D together with the SDK ARCore, in turn, are reproduced descriptive audios and environmental sounds. After, the child interacts with the system hardware by observing pictograms and answering questions that the device generates about what is learned, this by communicating between the Arduino Mega development board and the prototype pencil that simulates the crushing of a button. This system allows the student with special educational needs, to strengthen their knowledge, associating sounds and images, which has an impact on the development of their cognitive abilities, such as attention and concentration, influencing the improvement of their academic level
