Allow input by Gesture with any body part(s)(hand, facial, posture, etc)

For some users who are blind or deaf or hard of hearing, it is much easier and more natural to use gesture-based text input methods. This feature may allow text input using sign language, using handwriting, or swiping through letters (or swipe to form the pattern) on a virtual keyboard (onscreen or even in the air), and others.
