C Specification

The XrSystemDynamicObjectKeyboardPropertiesBD structure is defined as:

// Provided by XR_BD_dynamic_object_keyboard
typedef struct XrSystemDynamicObjectKeyboardPropertiesBD {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsDynamicObjectKeyboard;
} XrSystemDynamicObjectKeyboardPropertiesBD;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • supportsDynamicObjectKeyboard is an XrBool32, with XR_TRUE indicating that the system supports tracking keyboard, and XR_FALSE indicating that the system does not support tracking keyboard.

Description

An application can inspect whether the system is capable of tracking keyboards by chaining an XrSystemDynamicObjectKeyboardPropertiesBD structure to the XrSystemProperties::next chain when calling xrGetSystemProperties.

If XrSystemSpatialSensingPropertiesBD::supportsSpatialSensing is XR_FALSE or XrSystemDynamicObjectTrackingPropertiesBD::supportsDynamicObjectTracking is XR_FALSE, then supportsDynamicObjectKeyboard must also be XR_FALSE.

If a runtime returns XR_TRUE for supportsDynamicObjectKeyboard, the system supports dynamic keyboard tracking. This implies that XrSystemDynamicObjectTrackingPropertiesBD::supportsDynamicObjectTracking and XrSystemSpatialSensingPropertiesBD::supportsSpatialSensing must also be XR_TRUE.

Note that supportsDynamicObjectKeyboard may be XR_TRUE, even if the application has not obtained the permission required by the system.

Evaluation of permissions takes place later, in the asynchronous operation started by xrStartSenseDataProviderAsyncBD.
