The Touch Pro controller has many more sensors that are exposed as buttons in the WebXR Gamepad object. There are 12 buttons starting at index 0. Buttons 0 to 5 are defined the same as the complex xr-standard mapping.

Button 6 - Thumb Rest

It also exists on the older controller, but now it also reports the pressure on the thumb pad.

Button 7 - Stylus Pressure

It reports the pressure on the stylus tip.

0 = No pressure
1 = Full pressure

Button 8 - Trigger Finger Curl

It reports how much your trigger finger is bent.

0 = Straight
1 = Bent touching the trigger

Button 9 - Trigger Finger Slide

It reports the position of your trigger finger on the trigger.

0 = All the way to the left
1 = All the way to the right

Button 10 - Trigger Finger Proximity

It reports if your trigger finger is far from the trigger.

0 = Close to the trigger
1 = Far from the trigger

Button 11 - Thumb Proximity

It reports if your thumb is far from the controller.

0 = Close to the controller
1 = Far from the controller

Additional Haptics

There is also access to three additional haptic actuators. You can find these as additional entries in the hapticActuators array. The first entry controls the main actuator. The second one controls the actuator in the trigger, and the third controls one under the thumb stick.
