    iOS 13將用AR“魔術”來彌補FaceTime最煩人的缺陷

    Xaiver Harding 2019年07月09日

    蘋果iOS 13 beta 3版本有了一項新功能:FaceTime使用者可以一直顯示為正對著攝像頭,即使你沒有這樣做。

    iOS 13 beta 3(即第三次公測)版本在上周二向iPhone軟件開發者開放,其中包括一些受人歡迎的改動。最引人注意的就是蘋果公司的FaceTime注意力糾正(Attention Correction)功能,它可以進行自動修正,從而讓使用者在視頻通話期間一直顯示為正對攝像頭。完成設置后,使用者看起來就像一直在注視著對方或者攝像頭,而不是低頭看手機屏幕。

    一位開發者在Reddit上表示,該功能在iOS 13 beta 3版本中很容易開啟,只需點擊FaceTime設置欄中的一個開關按鈕即可。將該按鈕設為開啟狀態后,在FaceTime上跟你通話的人就會看到你一直在注視著他們,而不是低頭看手機。一些已經下載該版本的用戶正在仔細研究此項功能的實際效果。傳感器智能研究公司Observant AI的聯合創始人戴夫·舒金說,FaceTime使用了蘋果的增強現實工具ARKit來掃描用戶面部,然后對眼睛周圍的區域進行調整。在用戶面前放一件物體后就會發現,FaceTime讓眼睛周圍的區域變得稍微彎曲了一些。

    這項新功能也許不需要掃描到用戶的瞳孔。就算帶著太陽鏡,它仍然可以對相關面部區域進行調整。

    讓人意外的是,只有最新型號的iPhone,也就是iPhone XS、XS Max和XR能夠使用此項功能,而在iPhone X等其他舊款iPhone上目前并未開放該功能。盡管iOS 13預計可以支持iPhone 6S、6S Plus及以后的型號,但iPhone 7和7 Plus用戶現在還不能下載iOS 13 beta 3。

    FaceTime注意力糾正是蘋果在iOS 13中測試的諸多新功能之一。這個版本于今年6月在蘋果開發者大會上發布。開發者和心急的粉絲都可參與公測,從而嘗試新功能,比如黑暗主題模式(即全系統夜間模式)、照片整理以及對Siri的更新。對隱私保護感興趣的用戶還可以在公測中使用蘋果一鍵登錄Sign In With Apple,屏蔽未知來電并對位置共享做出更詳細的限制。

    在范圍更小的開發者公測中,用戶可以下載包括FaceTime注意力糾正功能的iOS 13 beta 3。同時,他們還會發現app加載速度更快了。蘋果產品新聞網站9to5Mac報道,在iOS 13 beta 3中還可以看到iPhone手機之間有線傳輸數據的蛛絲馬跡。這大概是蘋果的手機克隆工具,可以把一部iPhone中的所有數據傳輸到另一部iPhone上。

    但對iOS 13 beta 3感興趣的用戶在安裝這個版本前要三思而后行,因為它有一些缺陷,其中一部分已經在蘋果的軟件發布通知中得到披露。有耐心的用戶可以等到今年秋天就應該可以使用iOS 13正式版了。(財富中文網)

    iOS 13 beta 3 was released to developer iPhones on last Tuesday, and with it came some welcome changes to Apple’s next operating system. Most notably, Apple’s new FaceTime Attention Correction feature was revealed, artificially changing where users appear to be looking during a video call. With the new setting enabled, users look like as if they are staring at the other person—or directly into the camera—instead of looking down at the phone’s screen.

    Turning on FaceTime Attention Correction is easy in iOS 13 beta 3, with a simple toggle in the Settings section under FaceTime, notes one developer on Reddit. Switch it on, and those you call using Apple’s video chat software will see you as looking at them and not your device.

    Some who have downloaded iOS 13 beta 3 for developers have started to dissect how it actually works. Dave Schukin, co-founder of Observant AI, says the software uses Apple’s augmented reality toolkit, or ARKit, to detect your face and then adjust the areas around one’s eyes. Putting something in front of a user’s face shows the software slightly bending the area around the eyes.

    FaceTime’s new feature may not rely on being able to see a user’s pupils. Even if a user is wearing sunglasses, FaceTime Attention Correction still warps the image around where one’s eyes would be—as seen here.

    Surprisingly, the software trick is only available on Apple’s latest handsets: the iPhone XS, XS Max and XR. iOS 13 beta 3 users on the iPhone X or other older devices are currently closed off from the feature. Even though iOS 13 is expected to support iPhone 6S, 6S Plus and later, the latest iOS 13 beta 3 is not available for iPhone 7 and 7 Plus.

    FaceTime Attention Correction is one of many new features Apple is testing with the release of iOS 13, introduced to the world in June at their developer conference. Both developers and eager fans can access Apple’s public beta, offering goodies like iOS 13’s dark mode, new photo-sorting features and updates to Siri. Those interested in protecting their privacy can make use of the new software’s Sign In With Apple, block unknown callers and more granular location sharing limitations as well, all available in the public beta.

    The even more exclusive developer beta, however, offers access to iOS 13 beta 3—which included the FaceTime Attention Correction. In addition, those with the developer beta can expect faster loading apps. The new beta also offers hints at a new way to potentially data from one iPhone to another via a cable, reports 9to5Mac. This, presumably, could be used as a migration tool, to transfer all of one’s iPhone data to another device.

    But users interested in iOS 13 beta 3 should proceed with caution when installing the software. The update contains some bugs, some of which Apple discloses in its software release notes. If you can hold off on the FaceTime Attention Correction feature for just a couple more months, iOS 13 is expected to release later this year in the fall.
