Since early 1990s haptic molecular modeling systems have been reported . To our best knowledge, the GROPE project started by B. Brooks et al in 1967 is the first one to introduce haptic technology to molecular modelling . Many of the pioneering works are for docking study of large biomolecular systems . Other pioneering systems are for feeling quantum mechanical force to an electron in a molecular system , for sensing force on electrostatic potential , and for virtual experience of molecular dynamics . Stabilization of haptic molecular systems was also studied . Those systems use a haptic device called PHANTOM , which is a force display with parts like an arm with pencil. HaptiChem is one of the systems at the early stage for haptic experience in chemistry. It is an intermolecular force display system, which makes it possible to touch and move molecules as feeling intermolecular force in a threedimensional virtual space by using a haptic device. HaptiChem uses a force display device SPIDAR , which was developed by Sato et al.
