This application provides graphic (wire-frame) representations of molecules and their inter- atomic forces to allow a user to adjust the relative position and orientation of molecules while searching for minimum energy binding sites. A series of systems have been developed, evolving from a 2-D system, through a 3-D system and a 6-D system for a simple docking task, to a full 6-D molecular docking system called GROPE-III. These later systems have employed a modified Model E-3 Argonne Remote Manipulator (ARM). </li> <li> Slide 16 </li> <li> CS6360 Virtual Reality David Johnson Gloves 1977 Sayre1977 Sayre Light tube attenuation to measure bend 1981 Grimes (Bell)1981 Grimes (Bell) Bend, tactile sensors 1984 VPL1984 VPL VPL DataGlove 1993 Utah/MIT1993 Utah/MIT Dextrous Hand Master (Hollerbach) Dextrous Hand Master, Exos </li> <li> Slide 17 </li> <li> CS6360 Virtual Reality David Johnson CAVE displays 1992 EVL1992 EVL Users in a projected room CAVE movie CAVE movieCAVE movie </li> <li> Slide 18 </li> <li> CS6360 Virtual Reality David Johnson CAVE displays CyberSphere (1998) The scientists Eyre and Eureka in VR-Systems UK have been researching a CyberSphere, a device, which consists of a large, translucent sphere containing the user. The images are distortion-corrected and then projected on the surface of the sphere, allowing the user a full 360 degree field of view. It also allows the user to move around in the world, by walking inside the ball, which will move in response to the users movements.
