Allow input by Gesture
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.
Discussion by Disabilities
Using gesture-based input that is unrestricted to accurate pointing can greatly simplify input for people are blind or have low vision.
Deaf and Hard of Hearing
Sign language recognition will allow users who are deaf or hard of hearing input text more easily and naturally.
