    Faced with greater competition, movie theaters have tried multiple experiments to upgrade the cinematic experience, including bigger and brighter screens and rumbling(折叠) seats. But a major challenge for exhibitors is to make the experience more attractive without depending on tricks.

One local theater, Regal L. A. Live, is experimenting with an idea that managers say strikes the right balance between so-called increase and sensory overload. The downtown L. A. theater plans to introduce Immersive Cinema Experience known as ICE technology in one of its auditoriums(礼堂) this fall.

The 190-seat auditorium will feature a traditional screen at the front, 1ike any other theater. But the audience will also have five LED screens on both sides that will flood moviegoers' peripheral (周围的 ) vision with lights and colors based on what's playing on the main screen. For example, if you're watching a scene that takes place in the African desert, the LED might shower the audience with enveloping colors of sky-blue, sun-like yellow sand. But importantly, viewers won't have to turn their necks to catch any additional onscreen action. "When you' re watching the movie, you actually feel very absorbed into the film," said Shelby Russell, a manager at L. A. Live. "It strengthens the mood of each of the scenes."

Regal L. A. Live will be the first U. S. theater to employ the technology. Managers did not say how much tickets will cost, but like other previous formats such as Imax, they will be more expensive than standard admissions.

Other cinemas have tried to introduce some other formats as theaters face growing threats from popular media. Results have been mixed, though. 4DX, which uses seat movements, water and scent effects, operates in more than 620 theaters around the world. On the other hand, Barcoo Escape, a once promising idea for a three-screen theatrical design, failed to catch on. Shelby said the success of ICE theaters in France, where it competes with Imax, indicates well for its U. S. expansion. "The problem with other formats is that they distract the moviegoer from the film," Shelby said. "ICE appeals to a very large audience."
