Now, 'World's first 3D visor' by Sony

Sony unveiled what it calls the world's first three-dimensional head mounted display, a device that enables its wearer to experience cinema-like virtual screen viewing.

Sony on Wednesday unveiled what it calls the world's first three-dimensional head mounted display, a device that enables its wearer to experience cinema-like virtual screen viewing.

The Personal 3D Viewer (HMZ-T1), is a visor-like gadget weighing only 420 grammes (14.7 ounces) that wraps around the head and enables its wearer to view high definition 3D images using two panels mounted in front of each eye.

The device is tethered to a processor unit and boasts surround-sound via earphones, giving the viewer 'a very realistic feeling of actually being there,' Sony said in a statement.

It said the display offered the experience of watching on a 750-inch virtual big screen 20 metres (65 feet) away.

Sony said children aged 15 and younger should refrain from using the display, while warning it could trigger travel sickness when used in unstable environment such as a vehicle.

The electronics giant, maker of Bravia flat screen televisions and PlayStation game consoles, has tried to incorporate 3D functions to a wide range of its products.

Sony plans to release the device in Japan on November 11, with initial pricing expected to be around 60,000 yen ($783).
