Oslo Events

For easily scraping data from the ADB logs to access the Motion Sense data on the Pixel 4/4 XL. This is named Oslo because Oslo was the code name while the Pixel 4 was in development. It is part of a wider project known as Project Soli

npm i oslo-events

1. Install the dependency above.
2. Download adb tools and connect your Pixel 4 or 4 XL to your computer by USB debugging. Ensure the path variable to adb is set correctly. For more info on setting this up, see more on how to configure on-device developer options.
3. Create a file and subscribe to events of your liking. These take the classic form of .on(event, callback) like so:

const Oslo = require('oslo-events');
const oslo = new Oslo();
oslo.on('flick', (data) => {
    // do something fun
    console.log(data);
});

oslo.on('FLICK 1 SOUTH', () => {
    console.log("USER FLICKED SOUTH");
})

Events with data

These event names will return a data payload

• flick
• reach
• status
• presence
• swipe

These will only fire if something is subscribed to listen to that event. (e.g. the flick event only triggers if media is playing).

Events without data

• FLICK 1 WEST
• FLICK 1 EAST
• FLICK 1 SOUTH
• FLICK 1 UNKNOWN
• REACH 1
• REACH 0
• PRESENCE 1
• PRESENCE 0

These events always fire, regardless of subscription status.

ADB Troubleshooting

If you experience issues getting this to run (e.g. you get the -- wating for device-- message), you may need to set the USB mode on your phone to file transfer mode, as well as enabling USB Debugging mode.

Cool Example

If you have Ubuntu, lock your screen when your Pixel detects you leave

const {spawn} = require('child_process');
const Oslo = require('oslo-events');
const oslo = new Oslo();
// when the user leaves
oslo.on('PRESENCE 0', () => {
   // send a terminal command to lock the screen
   spawn('xdg-screensaver', ['lock']);
});
