東京是世界上人口密度最大的城市之一，這里居住著無數獨居女性，這些單身女孩很容易成為犯罪分子的目標。為了避免她們在生活中遇到危險，日本一家公司設計了“窗簾上的男友”，通過一個由智能手機控制的投影儀，把一名男性的動態剪影投射到窗簾上，從外面看，就像家中有人陪伴，這樣就不容易被犯罪分子盯上了。

Because most Japanese people don’t really like the idea of having a roommate, a lot of these young people end up living alone, including young women. While Tokyo is much safer than large cities in many other countries, crimes do happen, and criminals often consider young women who live alone to be easy targets.
因為大多數日本人不太喜歡和室友同住，很多年輕人都是獨居，其中包括年輕女性。盡管與許多其他國家的大城市相比，東京要安全得多，但也有犯罪發生，獨居年輕女性往往被罪犯視為容易下手的目標。

To help address this problem, and also to put the minds of female tenants at ease, apartment management company Leo Palace 21 has developed what it calls the Man on the Curtain system.
為解決這個問題，讓女性住戶安心，物業管理公司Leo Palace 21開發了一個名為“窗簾上的男友”的系統。

Using a projector controlled by/attached to a smartphone, Man on the Curtain throws a silhouette of a man onto your curtains, so that when people outside look at your windows, there will appear to be a guy inside, thus masking that you live alone.
這個系統通過一個由智能手機控制的投影儀，把一名男性的輪廓投射到你的窗簾上，人們從外面看窗戶時，會看到一個男人的形象，這樣就可以假裝你不是獨居了。

If you’re wondering how that’s better than just putting a cardboard cutout by your window, Man on the Curtain is full-motion, projecting videos of actual actors (in silhouette) for an extremely lifelike look. Currently, the system has 12 different options, including such intimidating routines as a boxer throwing practice punches, a martial artist going through a karate kata, a bodybuilder working out with dumbbells, and a sports fan swinging a baseball bat around.
你可能在想這比在窗戶上放一塊紙板好在哪里。“窗簾上的男友”是全動態的，系統投射的是真實演員的剪影視頻，看起來非常逼真。目前，該系統有12款不同的選擇，包括一些令人生畏的剪影視頻，比如練拳的拳擊手、練習空手道的武術大師、舉啞鈴鍛煉的健美愛好者以及來回揮舞棒球棒的體育迷。

More relaxed choices include a guy vacuuming…
還有更加閑適的項目，包括拿吸塵器清掃的男性

…folding laundry…
折疊衣物的男性

…and doing yoga, which seems like it could double as a fitness video that you could do yourself in tandem with your shadowy protector.
還有做瑜伽的男性，你似乎還可以把它當成一段健身視頻，和你的影子保護者一起運動。

Since it’d be easy to deduce that a short loop is a fake, each video is roughly 30 minutes long, with a variety of motions.
因為短短一小段循環視頻容易被識破，所以每段視頻長度大約有30分鐘，里面有各種各樣的動作。

Granted, some of the options, such as the man vacuuming or playing guitar, aren’t going to be as effective if a would-be criminal is close enough to the window to notice the lack of sound. But the images themselves are very convincing.
當然，如果犯罪分子離窗戶很近，拿吸塵器打掃和彈吉他等男性剪影視頻就會露餡，因為他們會注意到房間里并沒有聲音。但剪影本身是很逼真的。
