Advanced Distributed Learning and ERP: interaction in augmented reality, haptic manipulation with 3D models and learning styles
Abstract
The Advanced Distributed Learning (ADL) is a learning process mediated by new technologies. The ADL also makes use of Augmented Reality, which takes place through processes of virtual manipulation. The experimental research on Augmented Reality markers and 3D objects focuses on the possibilities of interaction and manipulation of virtual forms in reality, that allows us to touch and interact with objects that do not exist but that are observable through a screen. Literature shows that there are different modules within the occipitotemporal cortex that receive both visual and somatosensory inputs and it explains how these can be integrated in the learning process. These cortical modules can be active in the evaluation of the various aspects of surface properties of objects, such as the 3D shape, as well as in visual and tactile movements. The purpose of this work is to analyze ERP components (P1, N2, P3) variations, during two different kinds of learning training (T): the same objects are manipulated either in Augmented Reality or during the condition of real haptic manipulation and the variations due to different learning styles are investigated. 12 university students were recruited for the study (mean age 23.11). The subjects were evaluated through a 4 scales style learning test: Visual Verbal (VV), Visual Non Verbal (VnV), Kinesthetic (K), Analytical (A). The subjects performed a training lasting 5 minutes consisting of haptic manipulation of 3D models, obtained through…
