透过实际场景看设计:发现缺失的需求
March 13th, 2009 by 奇遇
再次拿NOKIA E71的拍照功能说事。在拍照声音(拍照时的喀嚓声)设置里，仅能选择不同的喀嚓声。(声音非物理发声)
场景1：(注:此场景同样适用于在公共场合偷拍美女、不良现象、…)
王锋家里有未满周岁的孩子，孩子的睡姿特别可爱，于是十分高兴的拿手机拍照，不想发出响亮的喀嚓声，惊扰了浅睡(注:没养过孩子的不会理解“浅睡”对于孩子的意义)的孩子，老婆也投来责备的目光。于是王锋想静音拍照时的“喀嚓”声。打开拍照声音设置，却发现只能选择不同的拍照声，没有类似“无声”的选项，也找不到可以静音的设置项；又尝试着把整个手机设置为“无声”模式，但拍照时仍发出“喀嚓”声。万般无奈之下，王锋只好选择了一个听起来不太响亮的拍照声，尽管很不喜欢这个声音。在孩子浅睡时，尽量不在他身边用拍照功能了。
(这个场景或许有点吹毛求疵，但却让用户心理很难受，本该很容易想到的需求。如果你用来偷拍美女，或许你不会再认为是吹毛求疵。^^嘎嘎)
场景2：
杜宾在一次听课时，老师版出了一个很重要的表格，抄下来实在太麻烦，又没带数码相机，凑合用手机去拍几张吧。为了不发出声音影响老师讲课，于是杜宾想先静音拍照时的“喀嚓”声。打开拍照声音设置，却发现只能选择不同的拍照声，没有类似“无声”的选项，也找不到可以静音的设置项；尝试着把整个手机设置为“无声”模式，然后拍照，拍照时仍发出“喀嚓”声。为此老师还特意提醒拍照时关掉声音，搞的自己好像挺没素质似的。
缺失需求：静音拍照声。静音是一个很普通的需求，很多需要安静的场所都会有这个需求(比如：会议室、课堂、不惊扰拍摄对象等等)。
后记：
感谢大家对隐私问题的争论，甚至有人提出日本等已经通过法律禁止厂商提供手机拍照静音功能。搜索了才知道，日本通过禁止手机静音设置这样BT的法案了，美国也仅仅是提出了此项法案。这种通过限制手机功能而禁止偷拍的功能，不知道会收到多少成效！！如果视频偷录呢？是否应该发出点啥声音提示呢？如果提示，那么提示声会影响到录制的音效，没法办了吧？！
用户静音拍照是一个很常见的需求，大多数用户不会因为可以静音而去偷拍，偷拍的人不会因为可以静音而不去偷拍。不妨再想想，为了偷拍而禁止手机商不提供静音功能，实在可笑！如果想偷拍，岂能因为手机不能直接设置拍照静音而阻止偷拍，这些恶心的人有的是方法来静音拍照，搜一下就能看到不少这样的教程。

声音分2种：
1 拍照时机器的物理声响；
2 机器设计的一些拍照的“音乐声”，如文中提到的。
第一种 无法避免，因为成像的时候需要镜头里叶片关闭（手机成像构造不大清楚），但这种声音一般较小。
第二种 如果无法设置静音就比较差了，有待改进。
非物理发声，谢谢果伦提醒。
再次回奇遇的观点:道德无法用销量来衡量
曾几何时,很多拍照手机都具备拍照时无声的选项,,手机拍照的快门声为音效模拟,但是带来最突出的后果是很多女性在如厕时,在更衣时,在更多隐私的空间被不知不觉偷拍,当然这和手机厂商没有任何关系,但是手机厂商无法约束没有道德的用户存在,于是删除了某些看似很需要的功能,了解用户的需求,同样要了解用户的衍生需求,在人性道德和商业利益的权衡下,我选前者,你呢?
这又转移到企业公德心的问题 阿弥托福
真是相当的想当然
原因mouse都已经说了
友情提示 国内的山寨机很多都可以静音拍摄 建议选购
@Mouce ，我说的偷拍没有你想到那么龌龊，我只是想在欣赏某位美女时，有些淘气的小鬼做点留照痴情的傻事。
@路人，是否想当然，你亲身经历了，感觉难受了才会知道。
我写自己亲历的故事，虽然是小细节，也望各位也别拍脑门应答。如有异议，欢迎深度讨论，举出场景描述来更佳。
我觉得奇遇大哥blog成了 奇遇、Mouse和我的辩论堂了。
依然发表一下我的观点：
@Mouse
女性在如厕时,在更衣时,在更多隐私的空间被不知不觉偷拍，当然这和手机厂商没有任何关系……
1. 依你的意思手机厂商是因为这个原因关闭了这个设置功能了？ 手机厂商真够关爱女性隐私的。
2. 女性在更多隐私的空间被偷拍大多数是因为固定在这些地方的针孔摄像机，并非照相机。那按你的理由我们应该建议这些摄像厂商把产品设计为拍摄过程必需发出声音，以便提示这些女性。
这里扯到人性道德和商业利益未免有些牵强。
支持mouse的看法，这个问题简单的搜索一下就知道了。
不是手机厂商关爱，是有些国家有强制规定。不要把麻木当有趣。
相关国家法律一览：
香港律政司建议引用普通法的“破坏公众体统罪”控告偷拍者，以取代目前刑罚较轻的“游荡”罪名。疑犯一经定罪，最高可判入狱7年。
韩国要求用照相手机拍摄时必须自动发出响亮的快门声，以有效制止手机偷拍现象；
日本政府制订规范，禁止在公共浴室、更衣室等偷拍高发地点使用照相手机，而且所有日系手机拍照声都无法关闭。
英国政府禁止人们携带手机进入任何可能进行偷拍的公共场所。
美国芝加哥市规定，在公共浴池和淋浴间，未征得当事人允许，禁止对其进行拍照。芝加哥市议会提议，对违反规定的人处以5至500美元的罚款。
@ tanyear
多谢，这个是我无知。见笑见笑！
不知道中国是怎么规定的？摄像机的规定有吗？我去查查！
查了一下手机的拍照声：
这个是预防有人使用手机进行偷拍而设计的，很多手机的拍照声音是不能够被取消的，
如果你实在觉得拍照声音很烦人的话就只有刷机了，把原来的拍照声音的文件用无声的文件覆盖掉，这样拍照时就可以无声了，但是如果想再让拍照有声的话也很麻烦，需要重新覆盖刚才的声音文件。而且刷机有一定的危险，所以如果没有特殊需要尽量不要去做这个。
不知道你的手机能不能刷机？
具体成效待考证，我还是使用果伦的建议吧，自行制作无声的音乐文件。
我不喜欢使用手机发出声音，包括键盘按键音。可能仅是我个案，待考证。
@tanyear ，谢谢8楼的分享。
我想说的8楼已经说了，呵呵
路过就留个言吧@！
@Mouce ，感谢提出的问题。日本通过禁止手机静音设置这样变态的法案了，美国也仅仅是提出了此项法案。如果视频偷录呢？是否应该发出点啥声音提示呢？如果提示，那么提示声会影响到录制的音效，没法办了吧？！
用户静音拍照是一个很常见的需求，大多数用户不会因为可以静音而去偷拍，偷拍的人不会因为可以静音而不去偷拍。不妨再想想，为了偷拍而禁止手机商不提供静音功能，实在可笑！如果害人想偷拍，岂能因为手机不能直接设置拍照静音而阻止偷拍，这些恶心的人有的是方法来静音拍照，搜一下就能看到不少这样的教程。
对呀，上边我就疑问，视频偷录才是偷拍的关键啊！特别是针孔，按这些法律的逻辑，也该加上点声响啊！
事情的两面性,如何权衡….
所以”产品人员”在用”产品”的时候思考一下对方设计时所受到的限制是一个很好玩的事,但是貌似现在成了我的职业病….. 而且在提高我的忍耐度……
依然是: 事情的两面性~
照相机的体验是最重要的。至于被利用当做违法工具应该是政法部门的事情。不能因为有些人使用照相机违法，就把所有的人都假想成嫌疑人。
@奇遇 如果使用自己的无声音乐文件 是否有点多此一举了？厂商直接增加无声设置不就解决？？
貌似以前看到过一条新闻，有一种高科技设备：可以探测到附近是否有拍照设备的仪器。建议推广~~~在特殊的区域严禁携带拍照设想设备。
@jim，“厂商直接增加无声设置不就解决？？”你说的这句正是确实的需求。
经常来您的站来转悠。学习到不少东西。还能和大家交流。收获不小。所以自己也想开个BLOG，发表一些自己对某些产品的看法。只可惜现在blog和bbs都不能备案~~~~ 郁闷啊~~~~~
我也经常为这个问题感到烦恼
