Input

1. Press all buttons once to see if the corresponding display changes.
2. Input
3. Slowly move the stick around and check the center, outer circumference, left, right, top and bottom values.
4. Press the trigger step by step to see if it changes smoothly from 0 to the maximum value.

How to see the dead zone

If the axis value moves significantly even when you release your hand, it may be due to stick drift or correction settings. Since small shaking varies depending on the model, it should be determined based on the actual game's dead zone setting.

The button numbers and axis numbers displayed by the browser may differ depending on the OS, connection method, and controller.

Specific example: If the stick moves even though you are not touching it

Observe the axis value for a few seconds with your hand off, and see if it stabilizes around 0. Draw a circle slowly and see if it changes smoothly to the maximum value or if it doesn't reach in a certain direction.

Small vibrations occur as a characteristic of the equipment. Change the dead zone settings on the game side little by little, and find a value that accommodates both the impact on operation and arbitrary input.

1. Connect your controller and press any button to recognize it.
2. Select the display format that is closest to the actual device and press all buttons one by one.
3. Move the stick up, down, left, right, and circumferentially to check the axis values.
