virtual reality
Early head-mounted display device developed by Ivan Sutherland at Harvard University, c. 1967.
Virtual reality (VR) assisted scientists in studying how drug molecules bind to proteins through Project GROPE, an initiative started in 1967 at the University of North Carolina by Frederick Brooks.1
To enhance the perception and comprehension of molecular interactions, the system utilized the following methods:
- Visual Representation: It employed wire-frame imagery to depict molecules and the physical forces acting upon them.1
- Haptic Feedback: Scientists used special hand-grip devices to receive tactile feedback, allowing them to "feel" the forces involved in molecular docking.1
- Interactive Manipulation: By "grasping" these virtual representations, researchers could physically arrange molecules into a minimum binding energy configuration.1
This immersive approach enabled scientists to explore the virtual world of molecular docking much like flight trainees learning to operate instruments in a cockpit. By manipulating these virtual models, researchers were able to hypothesize and develop new drugs based on their findings.1
