我可以将智能手机加速度计数据用作秤吗？ [英] Can I use smartphone accelerometer data as a weighing scale?

问题描述

是否可以将智能手机中的原始加速度计数据用作秤？因此，通过在屏幕上放置一个对象，应用将对对象和屏幕上显示的重量进行称重。

Is it possible to use the raw accelerometer data from a smartphone as a weighing scale? So, by placing an object on the screen, the app would weigh the object and the weight displayed on the screen.

如果不可能的话，可以使用其他功能吗？

If it is not possible, could some other function of the smartphone estimate the weight of an object?

推荐答案

否。可以使用加速来推断对象的质量，但是需要特殊的设置，例如阿特伍德机。传统上，Atwood机器依靠计时来计算两个物体的相对质量，但是您可以只使用加速度计来完成。

No. Acceleration can be used to deduce the mass of an object, but it requires a special setup such as the Atwood Machine. The Atwood machine traditionally relies on timing to work out the relative mass of the two objects, but you could do it with just the accelerometer instead.
