????在我親自測(cè)試這款應(yīng)用的過(guò)程中，我發(fā)現(xiàn)它在識(shí)別圖書,、視頻游戲封面上,，可以算得上是“秒開(kāi)”，但是在識(shí)別一般日常用品比如食品和清潔用品時(shí),，有時(shí)卻不是很順利,。比如有一次我掃描了一盒凱洛格公司的Special K薯片，但是這款應(yīng)用卻顯示它是一盒藍(lán)莓味的Special K餅干（不過(guò)第二次掃描成功了）,。當(dāng)我試圖掃描微軟的Xbox One游戲機(jī)或蘋果iPhone 5S手機(jī)時(shí),，F(xiàn)irefly根本就不識(shí)別它們。（你一定是故意的,，杰夫?貝佐斯,。）

????Firefly識(shí)別出一樣物品后，會(huì)給你提供一個(gè)在亞馬遜上直接購(gòu)買的選項(xiàng),。另外亞馬遜也允許第三方開(kāi)發(fā)者整合Firefly,。比如通過(guò)iHeartRadio等應(yīng)用，你甚至可以根據(jù)一首FireFly識(shí)別出的歌曲,，建立一個(gè)自己的音樂(lè)電臺(tái)——這樣就使它的功能遠(yuǎn)遠(yuǎn)超出了一臺(tái)簡(jiǎn)單的銷售終端系統(tǒng),。

????在這款手機(jī)首次發(fā)布時(shí),，亞馬遜的CEO貝佐斯努力想把Fire描繪成一種與眾不同的智能手機(jī)。在這一點(diǎn)上Firefly做得很不錯(cuò),。另外貝佐斯在發(fā)布會(huì)上提到的“獨(dú)特的用戶體驗(yàn)”,，其實(shí)來(lái)自一個(gè)叫“動(dòng)態(tài)視角”的功能。它本質(zhì)上就是亞馬遜耗時(shí)四年開(kāi)發(fā)的一個(gè)3D界面,。

????在手機(jī)上應(yīng)用“3D”社交并不是什么新鮮事,，比如HTC公司的Evo 3D和蘋果iOS系統(tǒng)的視差滾動(dòng)效果等等。不過(guò)Fire的不同之處,，在于它利用手機(jī)的四臺(tái)前置攝像頭來(lái)抓取你的頭部相對(duì)于手機(jī)屏幕的角度,。因此如果你想要調(diào)節(jié)顯示屏中物體的角度，你可以不用動(dòng)手,，只需要移動(dòng)你的頭就行了,，就像看真實(shí)世界的物體時(shí)一樣。

????當(dāng)你第一次體驗(yàn)這種視覺(jué)效果時(shí),，留下的印象的確很深刻,。但過(guò)了幾天后，這種新鮮感逐漸變淡,，你就會(huì)注意到一些信息以奇怪的方式從手機(jī)上“滑落”了,。（比如要想讓狀態(tài)欄在屏幕上多停一會(huì)，好看一看剩余的電量,，簡(jiǎn)直像耍雜技一樣難,。當(dāng)然，手機(jī)上也有永久顯示狀態(tài)欄的設(shè)置,，但莫名其妙的是,，它是默認(rèn)禁用的。）

????在我禁用了動(dòng)態(tài)視角功能后,，這部手機(jī)的整體性能大大提高了,。使用APP的卡頓、解鎖時(shí)的延遲統(tǒng)統(tǒng)消失了,。（不過(guò)攝像頭的遲鈍反應(yīng)仍讓我稍嫌不足,。）我覺(jué)得手機(jī)的續(xù)航時(shí)間可能也相應(yīng)提高了，不過(guò)這很難說(shuō)——在我的測(cè)試過(guò)程中,，幾次續(xù)航時(shí)間的差異很大,，有時(shí)我大部分時(shí)間把它放在車上的杯托里，它只能堅(jiān)持11個(gè)小時(shí),；有時(shí)我整天都在把玩,，包括用它給孩子從網(wǎng)站上放動(dòng)畫片，但它卻能堅(jiān)持一整天,。

????亞馬遜的應(yīng)用商店里可以找到大多數(shù)我們期望的常用應(yīng)用,，比如Facebook、Instagram和Twitter等,。值得注意提星巴克（Starbucks）和Fourquare這兩個(gè)常年占據(jù)我自己手機(jī)主頁(yè)的應(yīng)用,，在亞馬遜的應(yīng)用商店里卻下載不到。（由于對(duì)應(yīng)用的偏好眾口難調(diào),，或許你的感覺(jué)跟我不一樣,。）

????在拿到Fire手機(jī)的那一刻，你就會(huì)發(fā)現(xiàn)這部手機(jī)存在的主要原因,，就是銷售亞馬遜的產(chǎn)品和服務(wù),。當(dāng)然從這一點(diǎn)上看，它和你口袋里現(xiàn)有的智能手機(jī)也沒(méi)什么兩樣,，但是Fire表現(xiàn)得要更加直白些,。人們會(huì)被它的直白嚇得敬而遠(yuǎn)之嗎？這可難倒我了,。我想象著有一天,，我可以隨手掃描一樣喜歡的東西，然后讓亞馬遜的無(wú)人機(jī)把它投遞到我家里,。我已經(jīng)迫不及待想和妻子分享這種驚喜體驗(yàn),。（財(cái)富中文網(wǎng)）

????In my experience testing the app, I found that Firefly was flawless in zeroing in on book or video game covers, but struggled when tasked with identifying common items such as food or cleaning supplies. When I scanned the front of a box of Kellogg’s Special K Cracker Chips, the app identified it as a box of Blueberry Special K Bars. (A second attempt did the trick.) When I tried to scan a Microsoft Xbox One game controller or an Apple iPhone 5S, Firefly didn’t recognize them at all. (Message received, Jeff Bezos.)

????After Firefly identifies an item, it presents you with the option to purchase it directly from Amazon. The company also allows third-party developers to integrate with Firefly—for example, iHeartRadio will create a radio station based off of a song identified by the app—extending its role beyond that of a point-of-sale system.

????During the phone’s debut, Bezos, Amazon’s chief executive, worked to paint the Fire as a different kind of smartphone. Firefly helps, but the “unique user experience” he alluded to comes from a feature called Dynamic Perspective—in essence a three-dimensional interface that Amazon has been working on for four years.

????The use of “3D” on phones isn’t new—see the sleight-of-hand employed by HTC’s Evo 3D, or the parallax effect in Apple’s iOS. The Fire approaches it differently by using the phone’s four front-facing cameras to track the location of your face relative to the screen. Instead of moving your hand to shift the perspective of the items on the phone’s display, you can move your head.

????It’s impressive the first time you experience it; a few days later, the feeling wears off, and you’ll notice information slipping off the display in odd ways. (Getting the status bar to remain on screen long enough to view battery percentage was a balancing act worthy of a Cirque du Soleil acrobat. Before anyone writes in, yes, there is a setting for making the status bar a permanent fixture, but critically, it’s disabled by default.)

????And here’s the kicker: After I disabled Dynamic Perspective, the overall performance of the phone vastly improved. The stuttering behavior I experienced as I whizzed through the app carousel? The delay in how quickly the lock screen appeared after I pushed the phone’s wake button? Essentially gone. (The camera’s sluggish burst mode still left me wanting.) I suspect I’ll find the phone’s battery life improved as well, though it’s difficult to tell —it varied wildly during my testing, from 11 hours parked in my car’s cup holder to a full day that included streaming cartoons for my kids.

????If you’re wondering, Amazon’s App Store carries most of the big-name apps we’ve come to expect such as Facebook, Instagram, and Twitter. Notably missing: Starbucks and Foursquare, two staples on my home screen. (Your mileage in this highly personal area may vary.)

????The moment you pick up Amazon’s Fire, it’s clear that the phone’s primary reason to exist is to sell Amazon’s products and services. In truth, that’s hardly different from the smartphone in your pocket today—but the Fire is less subtle about it. Will people be put-off by that harsh reality? Beats me. I’m too busy thinking about the day when I’ll be able to scan an item and have it delivered to my exact location by Amazon drone. I can’t wait to share that amazement with my wife.
