Detailed Description

Sense class which provides head pose tracking functionality to the SR system.

Member Function Documentation

create()

static HeadPoseTracker * SR::HeadPoseTracker::create ( SRContext &  context )

static

Creates a functional HeadPoseTracker instance.

Parameters

context

is the environment in which created senses are kept track of

Returns

HeadPoseTracker* which can provide streams of head pose data

The HeadPoseTracker class is abstract and requires a device specific implementation to be used in applications. This function constructs an HeadPoseTracker suitable for use in your application on the current device.

openHeadPoseStream()

virtual std::shared_ptr< HeadPoseStream > SR::HeadPoseTracker::openHeadPoseStream ( HeadPoseListener *  listener )

pure virtual

Creates a HeadPoseStream for listener to be connected to.

Parameters

listener

will receive head pose updates from now on

Returns

std::shared_ptr<HeadPoseStream> to be used to close the stream correctly when it is no longer required

streamClosed()

virtual void SR::HeadPoseTracker::streamClosed ( HeadPoseStream *  stream )

pure virtual

Closes a specific HeadPoseStream.

Parameters

stream

will no longer supply headpose updates
