????智能手機(jī)的現(xiàn)實(shí)增強(qiáng)技術(shù)

??? 普華永道會(huì)計(jì)師事務(wù)所（PwC）咨詢業(yè)務(wù)負(fù)責(zé)人、首席科技師克萊斯?卡倫說，不管你信不信，我們還沒有充分發(fā)掘iPhone的所有用途。“這些智能手機(jī)有很高的寬帶網(wǎng)絡(luò)連接，有GPS、指南針、加速計(jì)，有高分辨率相機(jī)顯示屏、攝相機(jī)、揚(yáng)聲器和話筒。”

????有些公司正在致力于解決這個(gè)問題，它們嘗試著把智能手機(jī)和平板電腦的功能聯(lián)系起來，為真實(shí)需求提供幫助。比如2009年，點(diǎn)評(píng)網(wǎng)站Yelp就推出了一款應(yīng)用，可以在手機(jī)的相機(jī)視圖上疊加一張所推薦餐廳的地圖。

????去年，現(xiàn)實(shí)增強(qiáng)領(lǐng)域取得了一些新的進(jìn)展。例如，第13實(shí)驗(yàn)室（13th Lab）針對(duì)Minecraft游戲推出了一款現(xiàn)實(shí)增強(qiáng)應(yīng)用。該游戲讓玩家對(duì)一個(gè)虛擬數(shù)碼世界進(jìn)行改造，借助這一應(yīng)用，玩家可以通過手機(jī)攝相頭，把它們建造的虛擬物品“放”在真實(shí)世界里。

????卡倫表示，同樣在今年，許多公司開始意識(shí)到，現(xiàn)實(shí)增強(qiáng)功能除了用于游戲之外，還可以做很多其它的事。卡倫表示，他已經(jīng)與一些醫(yī)療保健公司進(jìn)行了交流，探討如何利用人們的智能手機(jī)數(shù)據(jù)來預(yù)知疾病的傳播情況。

????A new iPhone reality

????Believe it or not, our iPhones are underused, says Chris Curran, principal and chief technologist in PwC's advisory practice. "These smartphones have high bandwidth connections. They've got GPS, a compass, and an accelerometer. High definition camera displays, a video camera, a speaker, and a microphone."

????Some companies are starting to address this problem by linking the capabilities of smartphones and tablets to augment the actual world. Yelp was one of the first to unveil an application, back in 2009, that uses GPS to layer a map of recommended restaurants on top of the phone's camera view.

????This past year has heralded new augmented reality advances. For example, developer 13th Lab released an augmented reality application for Minecraft, a game that lets users alter a digital world. The app lets users place the virtual objects that they build, via a phone camera, into the real world.

????Also this year, says Curran, companies have started to realize that augmented reality could be helpful for more than just games. Curran says he has spoken with health care companies to figure out how to use data from people's smartphones to predict how diseases spread.
