The latest doomed attempt to mount a virtual cinema atop the heads of geeks everywhere comes from the oddly named Mikimoto Beans of Japan. Its iTheaterV will be available there next month for ¥39,800 (£160).

Similar to systems we've seen before , the iTheaterV takes video from the source and displays it on two tiny LCDs in a pair of glasses to create the illusion of looking at a much larger screen. The virtual display is said to be a 65-inch screen at a distance of 2.5m.

Leg-up from Apple?

Another approach Mikimoto Beans has in common with other hawkers of head-mounted displays is its desire to piggyback on the success of the iPod - a cable and converter are included for hooking up to video from Apple's leviathan.

With a battery life of four to five hours and a weight of just 70g, the iTheaterV is clearly a well-engineered product - it's just a shame that the concept of watching video inside a pair of glasses is so fundamentally flawed as to be little more than a novelty.
