Tool guide
About Device Orientation Tester
Read orientation angles reported by the browser's motion sensor interface. Access may require HTTPS and permission, and the values describe device orientation rather than a calibrated measurement instrument.
How to use this tool
- 1Open the tester on a phone or device with supported motion sensors.
- 2Press Enable Orientation and grant permission if the browser asks.
- 3Tilt and rotate the device while observing the alpha, beta, and gamma values.
How the tool works
The page listens for device orientation events and displays alpha, beta, and gamma angles when available. Alpha is rotation around the device's vertical axis; beta and gamma describe tilt axes under the browser event convention. Sensor support varies.
Worked real-world example
Tilting a phone forward can change beta while rotating it in place can change alpha, though exact orientation depends on how the device is held.
Common scenarios and use cases
Check whether browser orientation access works or explore device motion in a web application.
Important details and limitations
Sensor readings can be noisy, unavailable, permission-blocked, or affected by calibration and device orientation conventions. Do not use them as a precision level or safety instrument.
Check the output unit as well as the number. If the result will be reused in another calculation, retain full precision where possible and round only at the end. For measurements governed by a technical specification, use the standard and tolerance required by that document.
Frequently asked questions
Why does the page ask permission?
Browsers restrict access to motion sensors for privacy.
Does it work on a desktop?
Many desktop devices do not provide orientation sensors.
Are the angles survey-grade?
No. They are browser sensor readings, not calibrated measurements.
