Advances in informatics enabled the inclusion of more senses in the interaction between user and machine. One of those senses is touch, made possible through the use of haptic devices/interfaces. Simulators with a haptic command/interface (such as the Novint Falcon, used in the scope of this study) provide realistic feedback in terms of both graphics visualization and force feedback, enabling the user to feel and instinctively understand several aspects of the simulation. The usage of this technology in specific contexts such as physics learning can be quite meaningful because user actions will result in force reactions. This practical approach is contrary to conventional physics teaching where concepts are taught using mostly theoretical approaches rather than experimental ones. This study aims to demonstrate that virtual reality simulations with haptic capabilities are viable learning tools for physics education. The simulator presented in this article is divided in several modules, each addressing a specific area of physics. Developed modules so far relate to aerodynamics, friction and gravitation. The aerodynamics module allows the user to sense the forces applied to an airplane. The module portrays a 3D model of a Lockheed SR‐71b “Blackbird” and the user senses the thrust, drag, lift and weight as he moves the airplane inside the skybox representing the atmosphere. The gravitation module was developed as a game whose concept is to use a 3D model representing the Earth to divert asteroids into a collision course with the Sun. Gravitational forces are applied to the earth and to the asteroid, depending on the proximity between them. The asteroid’s trajectory will change and the user will feel the corresponding force. The friction module enables the user to drag a virtual cube over a flat surface and feel the corresponding friction force. The user is able to alter the material of both the cube and the floor which changes the static and dynamic friction coefficients. The use of these simulations in learning contexts is now being assessed. The first collected data is quite promising and it is expected to have a full set of results and conclusions in the next few months. [ABSTRACT FROM AUTHOR] |
