Haptic
Device

The Haptic API provides functions to control vibration.

Required Header

#include <device/haptic.h>

Overview

The Haptic API provides the way to control vibration functionality of a device. It allows the management of the device's vibrator parameters, such as the vibration count and level.

Related Features

This API is related with the following features:

  • http://tizen.org/feature/feedback.vibration

It is recommended to design feature related codes in your application for reliability.

You can check if a device supports the related features for this API by using System Information, thereby controlling the procedure of your application.

To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.

More details on featuring your application can be found from feature element description.

int device_haptic_open ( int  device_index,
haptic_device_h *  device_handle 
)

Opens a haptic-vibration device.

Internally, it makes a connection to the vibrator.

Since :
2.3
Privilege Level:
public
Privilege:
http://tizen.org/privilege/haptic
Remarks:
You must close the Haptic API using device_haptic_close().
Parameters:
[in]device_indexThe index of device what you want to vibrate
The index starts from 0
[out]device_handleThe handle of vibrator
Returns:
0 on success, otherwise a negative error value
Return values:
DEVICE_ERROR_NONESuccessful

See also:
device_haptic_close()
int device_haptic_stop ( haptic_device_h  device_handle,
haptic_effect_h  effect_handle 
)

Stops all vibration effects which are being played.

This function can be used to stop all effects started by device_haptic_vibrate().

Since :
