Gesture Keyboard - User centered design of a unique input device for Indic Scripts♦

devnagari text	Indic text input presents a unique challenge in the field of keyboard
entry, gesture	design because of the number of standalone characters, conjuncts, matras,
keyboard (GKB),	and symbols. It poses a huge challenge to the HCI practitioners to
matras, modifier,	accommodate the humongous array of Devnagari characters in a
syllable, IMEs	keyboard. Solutions for input in Devnagari scripts using a physical
	keyboard have been around for a while but none of them have emerged as
	a standard mechanism due to several usability related concerns. In this
	paper we have described the design of a new gesture based keyboard,
	which has a dual input mode 1. Gesturing 2. Tapping. The "gesture
	keyboard" concept is based on partial hand writing recognition as well as
	touch-typing paradigms. Conceptually, it is a stylus sensitive keypad that
	supports tapping for getting the base consonants and some symbols,
	while it also recognizes handwritten matras as per handwriting
	recognition methods. This paper also reports the findings of the user
	study, which was carried out to find the optimum sizes of the keys and
	layouts.
