C Specification

The XrSystemUserPresencePropertiesEXT structure is defined as:

// Provided by XR_EXT_user_presence
typedef struct XrSystemUserPresencePropertiesEXT {
    XrStructureType    type;
    void*              next;
    XrBool32           supportsUserPresence;
} XrSystemUserPresencePropertiesEXT;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.

  • supportsUserPresence is an XrBool32 value that indicates whether the system supports user presence sensing.

Description

The application can use the XrSystemUserPresencePropertiesEXT event in xrGetSystemProperties to detect if the given system supports the sensing of user presence.

If the system does not support user presence sensing, the runtime must return XR_FALSE for supportsUserPresence and must not queue the XrEventDataUserPresenceChangedEXT event for any session on this system.

In this case, an application typically assumes that the user is always present, as the runtime is unable to detect changes in user presence.
