A haptic feedback device is a device that establishes a kinaesthetic link between a human operator and a computer-generated environment. This paper addresses the bidirectional coupling between a commercial off-the-shelf (COTS) haptic feedback device and a general-purpose modelling and simulation environment. In particular, an open-source library is developed to couple the Force Dimension omega.7 haptic device with the 20-sim modelling and simulation environment. The presented coupling interface

... is also compatible with all the different haptic devices produced by Force Dimension. The proposed integrated haptic interface makes it possible to track the user's motion, detect collisions between the usercontrolled probe and virtual objects, compute reaction forces in response to motion or contacts and exert an intuitive force feedback on the user. A real-time one-to-one correspondence between reality and virtual reality can be transparently created. This allows for a variety of possible applications. Stability issues, performance issues, design and virtual prototyping challenges can be addressed and investigated for research purposes. In addition, design and virtual prototyping are also of interest to industry. Realistic training environments can be developed for the user considering different possible operations and stressing the importance of usability and user experience. Experiments based on using haptics technology in the field of education can also be easily performed. To demonstrate the potential of the proposed coupling, a case study is presented. Related simulations and experimental results are carried out.
