Abstract
A virtual inking device is created in response to a touch input device detecting a user's inking gesture. For example, when a user places one of their hands in a pen gesture (i.e. by connecting the index finger with the thumb while holding the other fingers near the palm), the user may perform inking operations. When the user changes the pen gesture to an erase gesture (i.e. making a fist) then the virtual pen may become a virtual eraser. Other inking gestures may also be utilized.
