Touch interaction with the virtual realm or, more specifically, the technology behind haptic interfaces has been a subject of intense study and experimentation over the last few years. The nuances of this field of science have been explored in detail to understand how the dynamics of position and force can beget varying results. Advancements in Haptic technology have opened up new avenues in the world of gaming. As a result, the boundaries between virtual reality and the actual world are shrinking by the day. The mobile haptic interface (MPI) featured here is part of an impedance device system, which includes a haptic interface supported on a mobile platform. Limitations to mobility inside the virtual realm are eliminated to a great extent and interaction from a head-to-toe perspective is feasible. The key issues addressed here are the adaptation of motion control algorithms to performance specs, and the utilization of position estimation algorithms to nullify the effect of varying dynamics and localization of the mobile platform on force rendering.
An effort has been made to ensure that the stunning realism of haptic rendering is not lost due to transient dynamics and other conditions. And, the system also employs classic haptic grasping algorithms that stem from friction cone and soft-finger contact models. This enables virtual manipulation of any task. Scoop for the techies – the software is based on the open source Haptic Library developed at Siena University.
