tl;dr
KrauseFx recently noticed a gap of how websites can determine the activity of the user based on the acceleration and gyro sensor built into modern smartphones, including the iPhone and Google Pixel.
Using that data, web apps can determine if the user is using their phone while
- sitting
- standing
- walking
- running
- driving
- taking a picture
- lying in bed
- laying the phone on a table
and probably more, including guesses if the user is actively using their phone at this moment, or even if they're impaired by alcohol.

This was an inspiration for a JavaScript library. I saw the demo of KrauseFx then I want to build a package for these.
Open the web-app on your mobile device
