Computer displays are integrated into eyeglasses and contact lenses. Similarly subtle devices provide two-way auditory communication. We are plugged into the Web at all times through very high-bandwidth wireless connection. Direct eye displays created by our glasses and contact lenses project transparent virtual images that hover in the air in front of us. These displays also allow users to enter virtual reality environments, where they can interact with patients and other doctors, none of whom need to be physically proximate.
Haptic devices allow physical examinations from afar.
It's now possible for medical technicians with relatively inexpensive equipment to bring health care to remote areas. Doctors routinely train in virtual-reality environments, which simulate the visual, auditory, and tactile experience of medical procedures, including surgery. The virtual environments allow interaction with physically remote or simulated patients. With a simulated patient, students and physicians taking CME can engage in a complete doctor-patient encounter, diagnose a condition, and recommend a treatment. Doctors routinely consult knowledge-based systems, which provide access to the most recent medical research and practice guidelines.
