How to add custom input to InputManager?

I’m making a gesture based game with Omek and Unity, but I’m having trouble figuring out how to add different input methods to the InputManager. Any help?

EDIT
I really should have been more specific with my issues, and I apologize for that. I’m attempting to use the CharacterController to move my player piece around, but this only takes input from the InputManager, which by default only uses joysticks or mouse/keyboard. I’m wondering if there’s a way that I could add gestures (aka add some outside input source) to that, or if I’m better off not using the Controller like I’ve been doing.

If you are talking about the number of parameters the input manager takes in, just change the ‘Size’ Number. Input Manager

Unity’s Input manager only takes input from supported devices. It also doesn’t allow you to change anything at runtime.
If you want either of thes features, you will need to manually add them yourself
