Detailed Description

The DoubleSwipeManager class inherits from GestureManager to implement a double handed gesture.

When the gesture is detected it provides the centroid of both hands as the mouse position and the offset variable is set with the diference of distances between the hands at the current frame with the hands from the previous frame.

Member Function Documentation

void DoubleSwipeManager::generateGestureData ( FrameData &  params )

virtual

generateGestureData This function generates the data needed for the gesture manager

Parameters

params

data of the frame needed for the gesture

This function is called every time that GestureManager::updateStatus is called and GestureManager::isGestureDetected returns True

Implements GestureManager.

bool DoubleSwipeManager::isGestureDetected ( FrameData &  params )

virtual

isGestureDetected determines whether the gesutre has been detected or not

Parameters

params

data of the frame needed for the gesture

Returns

true if and only if two hands are detected and each of them has at least a finger tip or a palm detected

Implements GestureManager.

void DoubleSwipeManager::onStatusActive ( FrameData &  params )

virtual

onStatusActive This function is called while the status is active, until the end counter reaches 0

Parameters

params

data of the frame needed for the gesture

Note that the status can be active serveral frames so this function is going to be called several times in a row.

Implements GestureManager.

void DoubleSwipeManager::onStatusFinish ( FrameData &  params )

virtual

onStatusFinish This function is called when the end counter reaches 0

Parameters

params

data of the frame needed for the gesture

After this function is called the state of the gesutre is going to be set as inactive. The function should not be called again until the status of the gesture has gone to active again.

Implements GestureManager.

void DoubleSwipeManager::onStatusInactive ( FrameData &  params )

virtual

onStatusInactive This function is called when the status is set to inactive

Parameters

params

data of the frame needed for the gestures

In case a gesture needs passive information this is the function where it should be recorded.

Implements GestureManager.

void DoubleSwipeManager::onStatusInit ( FrameData &  params )

virtual

onStatusInit This function is called the first time the init counter reaches 0

Parameters

params

data of the frame needed for the gesture

After this function is called the state of the gesture is going to be set as active. The function should not be called again until the status of the gesture has gone to inactive again.

In this function all the atributes that are going to be needed during the gesture should be initialized.

Implements GestureManager.
