Virtual System for Teaching-Learning of Initial Education Using a Haptic Device

摘要

This article proposes a teaching-learning system for children of initial education through haptic devices and 3D Unity software. The system has several virtual interfaces that will be chosen according to the age, skills and knowledge that the child needs to acquire or improve. The interface allows to view the environment where the user must do a task or activity by the teacher in charge. Which it can listen to the instructions issued by the system and then be executed, also it has an introduction that remembers the objective to be fulfilled according to the interface. Through the haptic device geomagic Touch, a trajectory tracking control is carried out, which allows the child to perceive by means of feedback of forces if the movement and the direction with which he makes the stroke is the correct one. In addition, it allows to acquire the input signals the same that are sent to an algorithm that validates the stroke of the uppercase, lowercase vowels and basic figures made by the child. Also, it indicates to the teacher the results in a qualitative way.
