OIS can handle force feedback devices.
 
==Usage==
Possible Ogre + OIS usage example
 
===Create input system===
 
====Ogre::FrameListener====
A interface class defining a listener which can be used to receive notifications of frame events.
A 'listener' is an interface designed to be called back when particular events are called. This class defines the interface relating to frame events. In order to receive notifications of frame events, you should create a subclass of FrameListener and override the methods for which you would like to customise the resulting processing. You should then call Root::addFrameListener passing an instance of this class. There is no limit to the number of frame listeners you can register, allowing you to register multiple listeners for different purposes. Note that a frame event occurs once for all rendering targets, not once per target.

====OIS::InputManager====
Base Manager class. No longer a Singleton; so feel free to create as many InputManager's as you have windows.
 
====OIS::Keyboard====

Keyboard base class. To be implemented by specific system (ie. DirectX Keyboard) This class is useful as you remain OS independent using this common interface.
 
====OIS::KeyListener====
To recieve buffered keyboard input, derive a class from this, and implement the methods here. Then set the call back to your Keyboard instance with Keyboard::setEventCallback

====OIS::Mouse====
Mouse base class. To be implemented by specific system (ie. DirectX Mouse) This class is useful as you remain OS independent using this common interface.
 
====OIS::MouseListener====
To recieve buffered mouse input, derive a class from this, and implement the methods here. Then set the call back to your Mouse instance with Mouse::setEventCallback
 
====OIS mouse button id's====
<syntaxhighlight lang="cpp">
// /Dependencies/src/ois/includes/OISMouse.h
enum MouseButtonID
{
MB_Left = 0, MB_Right, MB_Middle,
MB_Button3, MB_Button4, MB_Button5, MB_Button6, MB_Button7
};
</syntaxhighlight>
 
====API====
 
=====Ogre::FrameListener #include <OgreFrameListener.h>=====
======virtual bool frameRenderingQueued(const Ogre::FrameEvent &evt);======
Called after all render targets have had their rendering commands issued, but before render windows have been asked to flip their buffers over.
The usefulness of this event comes from the fact that rendering commands are queued for the GPU to process. These can take a little while to finish, and so while that is happening the CPU can be doing useful things. Once the request to 'flip buffers' happens, the thread requesting it will block until the GPU is ready, which can waste CPU cycles. Therefore, it is often a good idea to use this callback to perform per-frame processing. Of course because the frame's rendering commands have already been issued, any changes you make will only take effect from the next frame, but in most cases that's not noticeable.
Returns
True to continue rendering, false to drop out of the rendering loop.
 
=====OIS::InputManager #include <OISInputManager.h>=====
 
======static InputManager * createInputSystem (std::size_t winHandle)======
Creates appropriate input system dependent on platform.
Parameters
winHandle Contains OS specific window handle (such as HWND or X11 Window)
 
======static InputManager * createInputSystem (ParamList &paramList)======
Creates appropriate input system dependent on platform.
Parameters
paramList ParamList contains OS specific info (such as HWND and HINSTANCE for window apps), and access mode.
 
======static void destroyInputSystem (InputManager *manager)======
 
=====OIS::Keyboard #include <OISKeyboard.h>=====
 
======virtual void setEventCallback(KeyListener *keyListener)======
<syntaxhighlight lang="cpp">
// /OIS/OISKeyboard.h
/**
@remarks
Register/unregister a Keyboard Listener - Only one allowed for simplicity. If broadcasting
is neccessary, just broadcast from the callback you registered.
@param keyListener
Send a pointer to a class derived from KeyListener or 0 to clear the callback
*/
virtual void setEventCallback(KeyListener *keyListener) { mListener = keyListener;}
</syntaxhighlight>
 
=====OIS::KeyListener #include <OISKeyboard.h>=====
======virtual bool keyPressed (const OIS::KeyEvent &arg);======
 
======virtual bool keyReleased (const OIS::KeyEvent &arg);======
 
=====OIS::Mouse #include <OISMouse.h>=====
 
======virtual void setEventCallback( MouseListener *mouseListener )======
<syntaxhighlight lang="cpp">
// /OIS/OISMouse.h
/**
@remarks
Register/unregister a Mouse Listener - Only one allowed for simplicity. If broadcasting
is neccessary, just broadcast from the callback you registered.
@param mouseListener

*/
virtual void setEventCallback( MouseListener *mouseListener ) {mListener = mouseListener;}
</syntaxhighlight>
 
=====OIS::MouseListener #include <OISMouse.h>=====
======virtual bool mouseMoved (const OIS::MouseEvent &arg);======
======virtual bool mousePressed (const OIS::MouseEvent &arg, OIS::MouseButtonID id);======
======virtual bool mouseReleased (const OIS::MouseEvent &arg, OIS::MouseButtonID id);======
