If you want a widescreen television, but can’t squeeze a large set into your
living room, Sony has an answer. Its new Glasstron goggles use a virtual reality
headset display—a small LCD and lens system—which creates the image
of a widescreen TV that appears to hang in space 2 metres in front of you. The
goggles are simply plugged into a digital video disc player or a TV tuner. Sony
adds optional digital surround sound with Virtual Surround headphones, which
combine the five channels from the TV soundtrack into two, using phase shifts to
fool the ears into hearing sound from the front and rear as well as the
sides.
