Compass

by Keith Irwin

Compass is a web app written in plain HTML/CSS/JS. It uses DeviceOrientationEvent and geolocation to show a smartphone's GPS coordinates and polar orientation.

Instructions

Open compass.ki9.us on a smartphone with a compass. Hold the phone level and it should show your direction.

Is this accurate?

No, not really. Results may vary. As of this writing, Firefox and Chrome browsers handle the DeviceOrientation spec differently. It's only been tested on Chrome for Android.

Known issues

  • When the screen is rotated, the image gets rotated 90 degrees. I don't know how this could be fixed.
