TOKYO - Sony says it will start selling a head mounted display that provides a 3-D theatre of music videos, movies and games, targeting people who prefer solitary entertainment rather than sitting in front of a TV with family or friends.

Sony Corp. said Wednesday that the 60,000 yen ($800) "HMZ personal 3-D viewer" is set to go on sale Nov. 11 in Japan, and is planned for the U.S. and Europe, perhaps in time for Christmas, although dates have not yet been set.

Resembling a futuristic visor, HMZ, which stands for "head mounted display," is worn like chunky goggles-and-earphones in one.

The footage before the viewer — a music video of a Japanese singer in the demonstration for reporters in Tokyo — is crystal-clear and feels like peering into a dolls house in which a real-life tiny singer is moving.

It seems unlikely that most people — or even technology enthusiasts — will want to buy a product that involves sitting alone and wearing a little helmet. The HMZ might not be Sony's long awaited answer to Apple's iPod or iPad but just another quirky device packed with cutting-edge technology that is headed for a limited niche following.

A 3-D wearable gaming machine Virtual Boy from Nintendo Co., which went on sale in the 1990s, bombed, partly because of the bulky headgear required as well as the image being all red.

Sony's latest product is far more sophisticated. Sony officials said the gadget delivers the immersive experience of a home-theatre, or the equivalent of sitting in one of the best seats of a movie theatre.

The machine, which hooks up to Blu-ray disc players and game machines, is targeting people who want to enjoy movies or games alone.

It is not recommended for people 15 years old and younger because some experts believe overly stimulating imagery is not good for teenagers whose brains are still developing, according to Shigeru Kato, a Sony vice-president.

On the plus side, consumers are growing more accustomed to 3-D these days, with the arrival of 3-D TVs and game machines. Kato noted the most popular movies last year, including "Avatar" and "Toy Story 3," were 3-D.

HMZ uses Sony's own OLED screen, a relatively new kind of display that relays superb image quality and colour, compared to the more prevalent liquid crystal and plasma displays used in laptops and flat-panel TVs.

Kato said the major challenge had been making a very small display without compromising image quality.
