Question 1

What is a gyroscope?

Accepted Answer

A gyroscope is a sensor that measures the angular velocity or rotation of your device along the X, Y, and Z axes. It detects orientation and movement.

Question 2

What do alpha, beta and gamma angles mean?

Accepted Answer

Alpha (Z-axis) is the compass direction, beta (X-axis) is front-to-back tilt, and gamma (Y-axis) is left-to-right tilt. All are measured in degrees from 0 to 360.

Question 3

Is my sensor data private?

Accepted Answer

Yes. All sensor readings are processed locally in your browser. Nothing is sent to any server — 100% private.

Question 4

Why doesn't it work on my laptop?

Accepted Answer

Most laptops don't have gyroscopes. The tool works best on phones and tablets with built-in orientation sensors.
