Integration and acceptance of Natural User Interfaces for interactive learning environments

摘要

This study focuses on the design of interactive learning environments (ILE) enhanced with Natural User Interfaces (NUI) for educational applications. It presents a 3D virtual environment, namely THINKMOTION which enables students to practice computational thinking skills. THINKMOTION combines a visual programming interface for coding and creating 3D virtual scenes with physics simulations, with a gesture recognition system for interaction over virtual objects. The ILE integrates a NUI called Leap Motion Controller, which recognizes the users' hand movements and gestures A questionnaire was designed in order to evaluate the perceptions toward experimental learning with students of public and private secondary schools. It applies Technology Acceptance Model (TAM) and enhanced with new constructs such as perceived enjoyment and interface style. Results from our study highlight that: (1) NUI technologies positively impacted enjoyment and perceived ease of use among ILE users; (2) The ease of use provided by NUIs improved the enjoyment of students; (3) The perceived enjoyment considerably increased the intention to use; (4) For public school students, NUI technology has a significant impact on their first impressions and overall interest, followed by a positive attitude toward using ILE; (5) Private school students who are more accustomed to and familiar with using natural interfaces presented a positive attitude and enjoyment when using the ILE.
