Fast Virtual Keyboard Typing Using Vowel Hand Gesture Recognition

This paper proposes a fast virtual keyboard typing method that improves typing speed using hand gesture recognition. In the proposed method, five frequently used English vowels can be quickly input with five dedicated gestures. The proposed method reduces, not only the layer switching time of the multilayer keyboard layout, but also vowel typing time. To evaluate the performance of the proposed method, simulations are performed considering four scenarios according to the order of appearance of vowels and consonants. The experimental result shows that the proposed method improves typing speed by 23.07% on average compared to the previous method.
