Augmented Reality for the Development of Skilled Trades in Indigenous Communities: A Case Study

The main objective of this study was the design and validation of a mobile learning environment (ML) based on Augmented Reality (AR) visualization with the purpose of developing skilled trades in the field of carpentry in indigenous populations. A pedagogical model focused on lifelong learning was used, in order to promote the acquisition of skilled trades and knowledge in carpentry. The implementation of the ML environment was carried out in the Wayuu community, characterized by its high rate of poverty and limited access to education. During face-to-face meetings, three indigenous people participated in a learning process in which they were instructed on the use of trade tools and became familiar with the different types of trees and wood. To support this process, the AR was used together with the M-L environment. Subsequently, the participants built a chair applying the knowledge acquired during the learning process. During this stage, recordings of the indigenous people were made while they carried out the construction. Then, the performance of the apprentices was evaluated through a competency-based evaluation system, in which three experts analyzed the recordings. Finally, the three indigenous people were able to acquire skills in real time through their mobile device, following the instructions and observing 3D images and videos that showed the entire manufacturing process of a wooden chair, from sanding the material to final assembly and polishing. In addition, it was found that these indigenous people were able to successfully market the products they made in the carpentry workshop, thus improving their family income. The fundamental idea behind the pedagogical implementation of this model in the Wayuu indigenous community of northern Colombia is to provide them with training in various trades that allow them to obtain decent jobs and support their families. That is why the ML environment is ideal for vulnerable people, not only indigenous people, but also for those who are displaced, the elderly or deaf-mute. The visual approach used in this method dispenses with the need for voice and text making it accessible to everyone.
