Virtual proximity

Virtual proximity is a hypothesized form of telecommunication; utilizing helmet-mounted displays/real-time 3D imagers(to provide virtual vision) and linear resonant transducers(acting both as microphones and actuators, for touch) allowing for long-range "face to face" communication.

Facebook Inc. spent $2 billion USD(in stock options) to acquire the patent rights for Oculus Rift(the best-developed helmet-mounted display), likely in speculation of a future market for the technology.
