The Virtual Environments are more and more applied in industry to learn the manipulation of some complex and/or dangerous equipments. In this context, we are developing a virtual simulator dedicated for learning the manipulation of a specific forklift. In real use, this kind of forklift requires a physical involvement of people to manipulate it. This paper proposes thus an innovative haptic paradigm for the virtual driving of such a forklift. Within the virtual simulation, it aims to provide a sensorimotor stimulation which is close to the one that users have on the real forklift. Taking in account the physical behaviours of the real forklift (inertia, damping, turning radius), we haptically simulate the mechanical hinge constraints of the forklift handle to control the forklift direction. In addition, a specific haptic push/pull technique was designed to control the forklift velocity. Our hypothesis is that our paradigm is more realistic compared to classical interactive techniques, such as joystick without force feedback. To evaluate this realism, we conducted an ergonomic study of a driving task. The same driving task has been performed in three conditions: in large room with the real forklift (R), and in a Virtual Environment with a joystick (J), and with our haptic paradigm (H). We conclude that our hypothesis is verified when revisiting different acceptations of the realism concept in Virtual Environment, such as performance transfers, but also the behaviour and psychological processes transfers.
