????流言蜚語(yǔ)持續(xù)了幾個(gè)月之后，亞馬遜（Amazon）在本周三西雅圖的活動(dòng)上終于宣告進(jìn)入智能手機(jī)市場(chǎng)。

????面對(duì)以媒體人為主的觀眾，首席執(zhí)行官杰夫?貝佐斯發(fā)布了這家在線零售業(yè)巨頭的最新產(chǎn)品：Fire Phone手機(jī)。這款手機(jī)擁有4.7英寸的屏幕，2.2GHz的四核處理器以及2GB的內(nèi)存。通過(guò)手機(jī)側(cè)面的特定按鈕，用戶還可以使用高達(dá)1300萬(wàn)像素的攝像頭，同時(shí)享受亞馬遜Cloud Drive云存儲(chǔ)上的無(wú)限照片容量。

????正如傳聞所說(shuō)，這款手機(jī)由亞馬遜與運(yùn)營(yíng)商美國(guó)電話電報(bào)公司（AT&T）獨(dú)家合作推出，已經(jīng)出現(xiàn)在亞馬遜公司的網(wǎng)站上，32GB空間的兩年合約機(jī)起售價(jià)為199.99美元。亞馬遜還隨新手機(jī)限時(shí)贈(zèng)送一年的Amazon Prime會(huì)員服務(wù)。

????貝佐斯闡述了Fire Phone手機(jī)的物理參數(shù)及包括全新照片識(shí)別服務(wù)Firefly在內(nèi)的部分特性后，最終證實(shí)了傳聞，表示這款新產(chǎn)品在某種意義上擁有3D功能。貝佐斯展示了這款手機(jī)的運(yùn)動(dòng)追蹤屏幕。它采用了“動(dòng)態(tài)視角”技術(shù)，依靠在屏幕四角安裝的紅外攝像頭，讓用戶不需要借助3D眼鏡就能感覺(jué)到圖片的三維效果。

????貝佐斯演示了如何使用這項(xiàng)技術(shù)，讓手機(jī)上的圖片看起來(lái)更加真實(shí)。同時(shí)，當(dāng)用戶在手機(jī)上進(jìn)行在線購(gòu)物時(shí)，攝像頭還能根據(jù)用戶的頭部和面部移動(dòng)情況，記錄下用戶瀏覽過(guò)哪些產(chǎn)品。顯然，亞馬遜打算利用這項(xiàng)技術(shù)，鼓勵(lì)A(yù)mazon Prime會(huì)員多在網(wǎng)上購(gòu)買商品。用戶還可以通過(guò)傾斜手機(jī)，從而利用Fire Phone的地圖軟件進(jìn)行導(dǎo)航，也可以在閱讀新聞或Kindle電子書時(shí)啟動(dòng)“自動(dòng)翻頁(yè)”功能。

????周三的發(fā)布活動(dòng)開(kāi)始時(shí)，亞馬遜的股價(jià)幾乎沒(méi)有什么波動(dòng)，但當(dāng)貝佐斯的演示完成后，股價(jià)便上漲了超過(guò)3%。

????在今年早些時(shí)候就已經(jīng)有消息透露，亞馬遜可能將發(fā)布搭載3D技術(shù)的手機(jī)。移動(dòng)產(chǎn)品資訊網(wǎng)站BGR甚至還發(fā)布了照片，宣稱照片中的就是新產(chǎn)品的原型機(jī)。亞馬遜也在本月初推波助瀾，發(fā)布了一部推廣視頻，其中展現(xiàn)了幾位用戶面對(duì)從未見(jiàn)過(guò)的新產(chǎn)品時(shí)的驚訝反應(yīng)。視頻中的人們?cè)谑褂眯庐a(chǎn)品時(shí)，前后搖動(dòng)著腦袋，更加讓人們對(duì)新手機(jī)的頭部追蹤技術(shù)展開(kāi)了猜測(cè)。

????亞馬遜對(duì)現(xiàn)有和潛在的Amazon Prime會(huì)員推送了Fire Phone產(chǎn)品的信息。他們將來(lái)可以使用這款手機(jī)觀看流媒體，體驗(yàn)新發(fā)布的Prime Music。這是一款于本周一上線的音樂(lè)流媒體服務(wù)，讓Amazon Prime用戶能夠享受超過(guò)100萬(wàn)首音樂(lè)，而不必受到廣告的干擾。

????Firefly是Fire Phone手機(jī)的主要特色之一。這是一項(xiàng)照片識(shí)別服務(wù)，既可以識(shí)別文本和圖像，也可以識(shí)別音頻及視頻。這項(xiàng)服務(wù)在手機(jī)的側(cè)面擁有專屬按鈕，可以掃描電話號(hào)碼、書籍甚至藝術(shù)作品，讓用戶得到相關(guān)信息并存儲(chǔ)在手機(jī)中。Firefly還能識(shí)別歌曲和電視劇，或提供食物的營(yíng)養(yǎng)信息。

????After months of rumors, Amazon finally announced its entry into the smartphone market at an event in Seattle Wednesday.

????CEO Jeff Bezos spoke to a crowd made up mostly of members of the media to announce the online retail giant’s newest product: the Fire phone, a device with a 4.7-inch screen, a quad-core 2.2 GHz processor and 2 gigabytes of RAM. The new smartphone also features a 13-megapixel camera that can be launched by pressing a designated button on the side of the phone, and Amazon is offering free, unlimited photo storage on the Amazon Cloud Drive.

????As had been rumored, the phone is being offered in an exclusive partnership with AT&T and can already be found on the company’s website, starting at a price of $199.99 for a two-year contract with the 32-gigabyte model. For a limited time, Amazon is also offering a year-long Amazon Prime membership along with the new phone.

????After offering up info about the Fire’s physical specs and some of its features, including the new image recognition service Firefly, Bezos finally confirmed rumors that the new product has 3-D capabilities, in a sense. Bezos introduced the phone’s motion-tracking screen, which uses “dynamic perspective” head-tracking technology that relies on four corner-mounted infrared cameras to make images appear to be three-dimensional without the need for 3-D glasses.

????Bezos demonstrated how that technology can be put to use, making images on the phone’s display look more realistic while also registering the user’s face and head movements to cycle through Amazon products while shopping on the phone. To be sure, Amazon is aiming the new technology at Amazon Prime members to encourage them to buy more of the company’s products online. Users will also be able to tilt the phone to navigate the Fire’s maps feature and to initiate “auto-scroll” while reading a news article or Kindle book.

????Amazon’s AMZN 2.69% stock price, which remained relatively unchanged at the start of Wednesday’s event, rose more than 3% following Bezos’ announcement.

????News of a potential Amazon smartphone with 3-D capability leaked earlier this year, with BGR even posting photos it claimed featured a prototype for the new product. Amazon added fuel to the fire earlier this month when it released a promotional video featuring several people’s amazed reactions to an unseen product. The people in the video can be seen tilting their heads back and forth while using the product, which added to speculation over the phone’s head-tracking technology.

????Amazon is pushing the Fire to current and potential Amazon Prime subscribers, who will be able to use the phone to access streaming video and thenewly-launched Prime Music, a music streaming service launched on Monday that lets Amazon Prime members listen to more than one million songs without interruption from ads.

????One of the phone’s main features is Firefly, an image recognition service that can identify text and images as well as audio and video. Bezos said users can use Firefly, which has its own designated button on the side of the device, to scan phone numbers, books and even works of art to get information and save it on the phone. Firefly can also recognize songs and television shows, or offer nutritional information for food.
