Force Feedback Designed for Virtual Environments
Most virtual reality is based on sight and sound. Tangible Reality provides touching things. Users
can reach into a virtual environment and feel, touch, and grasp objects. The parts to this system include
a force feedback device, a computer, computer software, 3D graphics software and also software
to generate sound. Demonstration software is needed also. The "Phantom" (a force feedback device)
can be operated by a finger, a pen, or tool handles. Textures and hard objects can also be stimulated by
the system. Real time data is sent to the computer to update the visual scene. The physics based
simulation allows objects to move realistically. Currently this technology is being used to train
surgeons to perform delicate heart surgery. This software lets surgeons try out new techniques
without having the patient's life endangered from the surgery. Above the surgeons are using a "phantom" operating system. The computer generates an interface between the doctor and the patient.
