Detailed Description

Sense class which provides face tracking functionality to the SR system.

Member Function Documentation

create()

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

static

Creates a functional HeadTracker instance.

Parameters

context

is the environment in which created senses are kept track of

Returns

HeadTracker* which can provide streams of head position data

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

openHeadStream()

virtual std::shared_ptr< HeadStream > SR::HeadTracker::openHeadStream ( HeadListener *  listener )

pure virtual

Creates a HeadStream for listener to be connected to.

Parameters

listener

will receive head updates from now on

Returns

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

streamClosed()

virtual void SR::HeadTracker::streamClosed ( HeadStream *  stream )

pure virtual

Closes a specific HeadStream.

Parameters

stream

will no longer supply head updates
