华为新手机带压力感应屏 可称小东西重量
Huawei recently unveiled a phone that can be used to weigh small objects thanks to its pressure-sensitive screen, and now an app promises to add the same feature to the iPhone 6s.
近期，华为推出了一款新手机。这款手机应用压力感应屏，可称出小东西的重量。而现在，iPhone 6s也将在其系统中推出类似功能的应用软件。
Called Gravity, the app uses the handset's 3D Touch technology to turn the display into a scale, but Apple doesn't appear to be a fan of the app and has rejected it from the store.
Gravity was created by California-based design engineer Ryan McLeod who posted a blog about the development process on Medium.
It can be calibrated using quarter coins placed on a spoon and once calibrated, objects up to 0.8lbs (385g) can be weighed.
The spoon is necessary because, as Mr McLeod explained: 'We needed an object that was conductive, had finger-like capacitance, formed a single finger-like touch point, was a household item, and could hold items to be weighed.
'A spoon was the perfect solution we had been looking for.'
