A Natural User Interface implementation for an Interactive Learning Environment

Abstract

In this paper we present an interactive learning environment (ILE) called CRA y JUEGA, focused on the development of computational thinking skills using block-based visual language programing with a 3D physics simulation system. It includes a programmable interaction system based on hand movement and gesture recognition, that allows to easily create and use customized hand gestures for interaction with 3D objects in a virtual environment. By applying the TAM model to discover the motivation, enjoyment and behavioral intention to use, the results show that: (1) using NUI technologies in interactive learning environments improve the enjoyment and the perceived ease of use; (2) perceived enjoyment was a significant issue in the intention to use; (3) NUIs interfaces during exercises could provide motivation to learn for middle school students.
