Vitty: Virtual Touch Typing Interface with Added Finger Buttons

In this paper, we propose to add individual finger buttons to a nominal interaction controller to realize a QWERTY like touch typing experience in virtual reality. The method is called Vitty, and the intuition behind it is real life typing is emulated by mapping the fingers/buttons to the appropriate sectional rows in the virtual QWERTY layout. Vitty is expected to reduce the mental and physical fatigue in the usual aiming and selecting of each small alphanumeric keys. We compare the performance and usability of Vitty to those of the typing interfaces as available with the current popular VR interaction controllers, and found that with minimal training, Vitty can be an inexpensive yet viable alternative for text input for VR.
