3D技术为什么火不起来?

Peter Suciu 2012年10月24日

厂商们不断在设备上增加新功能,但除了《阿凡达》这样的大片上映期间带来的热潮,市场依旧对3D技术反应冷淡。但是现在多数情况下,人们需要额外佩戴特制的眼镜才能观看3D内容。分析人士认为,这个原因妨碍了3D技术的普及。

    3D技术曾被视为电影和视频演化史的下一个重大革新,是音效、色彩和宽屏格式发展到一定阶段后继往开来的新事物。然而,除了像《阿凡达》(Avatar)这类大片上映时激发了观众的热情,拉高了影院票房之外,3D技术在家庭中并没有真正获得追捧。上市三年后,人们对3D电视机的兴趣已经大不如前,哪怕它的价格已大幅回落。

    3D电影在电影院还只是一个小众市场,不过其市场地位颇为稳固。据市场研究公司IHS iSuppli称,3D电影占2011年票房总收入的19%。虽然3D电视机普及的速度仍然缓慢,但人们对包括便携式游戏机和手机在内的其他类型设备上的3D技术的兴趣预计将不断增长。市场研究公司NPD集团(NPD Group)显示器研究部门(Display Search)预测,3D电视机最终将迎来销售增长,从2011年的区区2,500万台增长到2019年的1.8亿台。

    此外,显示器研究部门还预测,3D技术将被运用到电视以外的几类产品上,包括手机和游戏机这类便携设备。任天堂(Nintendo)的3DS掌上游戏机就是这类设备中的一款热卖产品,它7月的总销量高达500万台。与多数3D电视机不同,这款游戏机采用了所谓的自动立体3D技术,用户无需佩戴特制的眼镜就能看到立体效果。

    其实,必不可少的3D眼镜正是导致3D需求不振的主因,因而它也饱受各方指摘。NPD 显示器研究部的新兴显示技术(Emerging Display Technologies)副总裁詹妮弗•科尔格罗夫称:“主动式眼镜很贵,而且还比较笨重。”

    由于每位观赏者都需要一副眼镜才能观看3D内容,否则图像会模糊不清,这个因素成为影响3D普及的一大障碍,而且事实证明这个问题很难解决。被动式眼镜则要便宜得多,LG些电视机厂商一直在推广被动式3D技术。迄今为止,只有东芝公司(Toshiba)推出过一款完全不需要眼镜的3D电视,但那些曾在1月份的消费电子展(CES)上看到过这款产品的人都对其价格和图像品质表示怀疑。科尔格罗夫补充称:“我们确实把这看成是购买3D设备的潮流开端,不过3D市场要发展壮大,必须是不需要额外配备眼镜,只用裸眼观看才行。”

    而内容仍有赖于技术,但只需要看看任天堂的3DS就能发现,这一技术可能依然存在缺陷。比如说,立体效果更像是模拟的,而不是真正让人身临其境的3D环境。有些人干脆怀疑,无论是否需要眼镜,3D电视机是不是真地能让人对便携设备上的3D技术感兴趣。研究公司M2 Research的资深分析师比利•皮德根称:“我发现,要全盘接受这项技术有点困难,也没看出来它会如何产生‘涓滴效应’(trickledown effect)。但我深信,很快所有电视机出厂时都会内置3D。到了这个水平,3D的渗透率就能得到提高了。”

    还会有哪些类型的设备内置3D呢?其中一个可能是手机,但美国市场上至今还没这种产品。IHS iSuppli的移动媒体部门资深首席分析师伊恩•福格称:“除了LG公司,还没有哪家公司在日本以外的市场推出过3D智能手机。实际上,手机屏幕普遍不支持3D,在不久的将来这种技术也不会大规模推广。”

    分析师称,这项技术要想取得成功,就必须变得更直观,并且要能应用于电视或电影之外的更多领域。福格称:“带有两个500万摄像头的3D手机是最直接的应用,这样用户就能创作自己的内容并在手机上回放。但是手机或平板电脑上的许多游戏用这项技术就会有问题,因为许多游戏——如赛车类游戏——会用到加速计,这就要求用户倾斜设备。这会给用免费眼镜观看3D画面的用户体验带来问题,因为如果不直视这种画面,它看起来就会失真。”

    而在用户的客厅里,应该成为杀手级应用——即游戏——的内容也并未如期推出。皮德根称:“微软(Microsoft)一拖再拖,索尼(Sony)一拖再拖,连任天堂也有点打退堂鼓的意思。这表明,市面上将会涌现出一大批3D电视机,因为有那么多厂商要卖这个产品,但这不意味着人们会看3D电视。只有当人们真正开始观看3D电视时,我才会相信这个技术的生命力。”

    3D was supposed to be the next big thing in the evolution of cinema and video, picking up where sound, color and the widescreen format had left off. But, aside from a small impact in movie theaters where blockbusters like Avatar drove interest, 3D hasn't exactly take off in the home. Going on three years interest 3D TVs have fallen flat, even as the prices have fallen too.

    At the movie theaters 3D is still a niche, but one that is holding steady. According to market researcher IHS iSuppli, 3D generated 19% of box office revenue in 2011. And while 3D TVs remain slow to catch on, interest in 3D on other devices, including portable game systems and mobile phones, is actually expected to grow. NPD Group's Display Search predicted that 3D TVs will eventually see sales increase, and grow from just 25 million units in 2011 to around 180 million units in 2019.

    Moreover, Display Search predicts that 3D will grow across several categories beyond TV including portable devices such as mobile handsets and game systems. One such device that has been seen as a hit is the Nintendo (NTDOY) 3DS handheld game system, which hit five million total sales in July. Unlike with most TVs, the game system utilizes so-called auto-stereoscopic 3D technology that does not require glasses for the users to see the effects.

    And, it has been the required glasses that have been blamed for the sluggish demand for 3D. "The active glasses are expensive," says Jennifer Colegrove, vice president of Emerging Display Technologies at NPD Display Search. "These tend to be bulky and heavy."

    As every viewer in the room needs glasses to view the content -- which appears blurry without glasses -- this has been a hurdle that has proved difficult to overcome. The passive glasses are far cheaper, and some TV makers such as LG have been pushing for passive 3D. But to date, only Toshiba has introduced a set that requires no glasses at all, and those who saw it at CES in January remain skeptical about the price and the quality of the picture. "We do see this as the start of a trend to have 3D," adds Colegrove, "but without glasses, with just the naked eye."

    The content will still depend on the technology, and one only needs to look as far as the Nintendo 3DS to see that it could have drawbacks. For one, the effect is more simulated than a truly immersive 3D environment. Some are even skeptical if 3D TV -- with or without glasses -- will lead to interest in 3D in portable devices. "I find it a little hard to swallow," says Billy Pidgeon, senior analyst at M2 Research. "I don't see how this will result in a trickledown effect, but I do believe that soon every TV going forward will have 3D built-in. That will increase penetration from that level."

    What other types of devices could include 3D? One possibility could be mobile phones, but so far none have arrived in America. "No one has released a 3D smartphone outside of Japan, except LG," says Ian Fogg, senior principal analyst for mobile media at IHS iSuppli. "Virtually no screens support 3D in the mobile space, and it isn't going to take off in the near future."

    For the technology to succeed, say analysts, it needs to become more intuitive and apply in more cases than just watching TV or moviews. "The mobile phones with 3D have two 5-megapixel cameras that were the most straightforward use, so users could create their own content and view it back on a screen," says Fogg. "But games on phones and tablets could be a problem as many titles -- such as racing games -- use an accelerometer that requires that you tilt the device. This in turn creates a problem for user experience with glasses free watching as the image doesn't look right if you're not viewing it straight on."

    In the living room, the content that should be the killer app -- namely games -- haven't been delivered as promised. "Microsoft (MSFT) has backed off it," adds Pidgeon. "Sony (SNE) has backed off it, and even Nintendo has somewhat backed off it. What this says is that there could very well be plenty of 3D TVs out there as that is what manufacturers will sell, but that doesn't mean people will be watching it. I'll believe it when I see it."
