A New Weapon for Battling Cellphones in Theaters: Laser Beams
Story Linky
BEIJING — Audience members using cellphones bedevil performers and presenters around the world. But in China, theaters and other venues have adopted what they say is an effective — others might say disturbing — solution.
Zap them with a laser beam.
The approach varies, but the idea is the same. During a performance, ushers equipped with laser pointers are stationed above, or on the perimeter of, the audience. When they spot a lighted mobile phone, instead of dashing over to the offender, they pounce with a pointer (usually red or green), aiming it at the glowing screen until the user desists.
Call it laser shaming.
“It’s usually only a small fraction of the audience that we have to deal with,” said Wang Chen, an employee in the theater affairs department at the Shanghai Grand Theater. “They can’t help themselves. So we try to give them a gentle reminder, so they know what they’re doing.”
Xu Chun, 27, who was in the audience for “Carmen” at the National Center for the Performing Arts in Beijing last month, said: “Of course it’s distracting. But seeing lighted-up screens is even more distracting.”
For the uninitiated, the appearance of a blazing colored beam in a darkened theater can be jarring.
“I remember the first time I saw the lasers, it was shocking to see that little red dot in the middle of a performance,” said Joanna C. Lee, a consultant for American symphony orchestras touring China. “Like someone was pointing a gun at the audience.”
Indeed, the narrow shaft of bright light can connote danger. Laser sights are a popular feature on firearms, and there have been numerous incidents in which lasers aimed at cockpits have impaired pilots’ ability to fly safely. (There are more benign uses for a laser pointer, of course, like making presentations and playing with cats.)
But laser pointers have been used for years as disciplinary devices at many of China’s leading performance halls, including the National Center, the Shanghai Oriental Art Center and the Shanghai Grand Theater.
This may be a response to a particularly acute problem here. Audience numbers have surged in recent years, along with the number of new performance spaces. And theatergoers are often noticeably younger than in the United States and Europe, with a corresponding lack of experience with Western-style concert etiquette. The lasers, theater managers say, are part of a larger effort to teach audiences how to behave during live performances.
Are the performers bothered by the use of lasers?
“No, it’s very smart, very fast, very effective,” Giuseppina Piunti, an Italian mezzo soprano, said backstage last month after singing the title role in “Carmen” at the National Center. “They should use the lasers all over the world. I can see the lasers from the stage, but it’s much less distracting than the flash cameras, and the ushers running up and down the aisles.”
The key, said Yang Hongjie, deputy director of the theater affairs department at the National Center, is to make ample use of the pointers early in a performance so that offenders (as well as nearby patrons) know what to expect should they dare to sneak a photo. <END>
> As a side note, several years ago, one of my friends brought me a "camera phone disrupter" from Hong Kong, It looks similar to the IR panel used by hearing-impared devices, however, what it does is emit extremely bright, but invisible to the eye, flashes of IR light. Since the imaging chips in most electronic cameras and phones can 'see' into the IR light range, it totally 'confuses' the auto exposure mechanism, causing the picture (still or video) to come out unusable.
I've 'played' around with it at home, but never tried it in a theater. I've never measured the pulse frequency to see if it would interfere with IR hearing devices. Maybe one of these days.......

quote: Mike Blakesley While the idea is great, it looks like a lawsuit waiting to happen. All it would take is one person getting the laser reflected back into their eyes, getting "zapped" and suddenly developing blurred vision, severe headaches, mental stress, inability to concentrate at work, and several other things a good lawyer could drum up.
Yeah, although It's not like any of those low powered lasers could do any more harm than a bright flashlight could do, but mention a certain buzzword on their "evil list" like "laser" or "nuclear" and people tend to go into frenzy mode, although nothing really ever happened.
quote: Louis Bornwasser Just build a Faraday cage around the auditorium.
Has been discussed before. Building a Faraday cage around any decently sized auditorium that actually works for this purpose is close to impossible.
quote: Frank Cox I don't have very much of an issue with cell phones here at all, probably because I'm consistent and always on top of it right away.
It obviously also depends a lot on your audience. While I agree that a no-tolerance policy is key in combating this problem, it's not always as easy to enforce, especially if you're running a multiplex with the bare minimum level of staffing.
