Gyroscope Test
Read 6-axis motion data from PS4 and PS5 controllers over WebHID. Live gyro and accelerometer visualization for aim training.
WebHID is required for low-level controller access. Use Chrome, Edge, or Opera on desktop.
- Connect the DualShock 4 or DualSense over USB.
- Click Grant device access.
- Rest the controller flat. Gyro should read near zero on all axes.
- Rotate to verify yaw, pitch and roll respond independently.
What the Gyroscope Test does
DualShock 4 and DualSense controllers include a 6-axis IMU (gyroscope plus accelerometer). This tester reads the raw motion samples over WebHID so you can verify gyro aim works, diagnose a drifting IMU, or benchmark noise floor before you commit to gyro aim in a competitive game.
How to run the test
- Connect the DualShock 4 or DualSense over USB.
- Click Grant device access and pick the controller.
- Rest the controller flat. Gyro should read near zero on all three axes; accelerometer Z should read roughly 1g.
- Rotate the pad in yaw, pitch and roll. Each axis should respond independently.
What a 6-axis IMU actually measures
The IMU is two sensors in one chip. The gyroscope measures rotational velocity around three axes (pitch, yaw, roll) in degrees per second. The accelerometer measures linear acceleration on three axes in units of g. Together they let a game reconstruct how the controller is being moved and pointed. Gyro is what makes gyro aim work; accelerometer helps distinguish upright from tilted.
How to check for a healthy IMU
Rest the controller absolutely flat on a table. The gyro should read within 1 to 2 degrees per second on each axis, and never more than 5. Accelerometer Z should read roughly 1g (gravity), X and Y should read near zero. If gyro reads 20 or more when the pad is still, the IMU is either miscalibrated or physically damaged.
Why gyro aim is worth learning
A thumbstick has maybe 100 discrete positions on each axis before software interpolation. A gyro reports rotation with far higher resolution and no dead zone. Splatoon players routinely outperform mouse users in tracking specifically because gyro is faster and finer than a stick. If your game supports gyro (via Steam Input if not natively), it is worth training on it.
Calibrating a drifting gyro
Some DualSense units ship with a gyro that reads a few degrees per second even when perfectly still. Games usually apply a software calibration on startup that reads the current gyro output and subtracts it as a bias. If your game supports a manual gyro calibration button, use it while the controller sits flat. Steam Input has one in the controller configurator.
