Say it with us: Kids today have it sooooo easy. A new smartphone app will do their math homework for them, provided it's not too complicated. PhotoMath by microblink uses a phone's camera to solve equations and then teaches you the step-by-step method for solving it yourself. The app can do arithmetic: addition, subtraction, division and multiplication. It can handle fractions. It knows what 23 is and can calculate the root of 246. It can even do simple linear equations, provided the x you're solving for is italicized so the app doesn't confuse it with the x multiplication symbol. The only catch is that the equation you're trying to solve must be printed text, rather than handwritten. So forget trying to calculate that tip by scribbling it on a restaurant napkin. (Don't worry, there's already a million apps for that.) The app may pose a problem for schools are already dealing with smartphone overload. Math teachers will have to be extra vigilant during tests to prevent students from cheating. The PhotoMath app is available for iPhones and Windows phones and is coming to Android phones in 2015. |
跟著我們一起說(shuō)：今天的孩子們過(guò)得太舒服了。 據(jù)CNN10月22日?qǐng)?bào)道，Microblink公司推出了一款新型智能手機(jī)應(yīng)用PhotoMath， 能輕松幫助學(xué)生解決數(shù)學(xué)題——只要不是太復(fù)雜。只需要將手機(jī)的攝像頭對(duì)準(zhǔn)要計(jì)算的方程式，PhotoMath便會(huì)給出清晰的解題步驟。 PhotoMath目前可以解決基本運(yùn)算加減乘除，還能處理分?jǐn)?shù)。例如，它可以計(jì)算出246的根以及23的值。它甚至還能解決簡(jiǎn)單的線性方程。不過(guò)，在使用時(shí)，用戶需保證x是斜體的，否則PhotoMath不能區(qū)分出x和乘號(hào)。 不過(guò)，PhotoMath目前只能識(shí)別打印字體的方程，手寫的還無(wú)法識(shí)別。因此，不要去嘗試用PhotoMath去解決寫在餐巾紙上的問(wèn)題。（別擔(dān)心，其它很多應(yīng)用都能識(shí)別手寫體。） 這款應(yīng)用可能會(huì)造成問(wèn)題，因?yàn)閷W(xué)校已經(jīng)在處理智能手機(jī)的很多問(wèn)題。為了防止學(xué)生在考試時(shí)用PhotoMath作弊，數(shù)學(xué)老師在監(jiān)考時(shí)需十分警惕。 目前，這款應(yīng)用支持iPhone和Windows phone用戶，而Android用戶則要等到2015年。 （譯者 Stellaliu 編輯 祝興媛） 掃一掃，關(guān)注微博微信
