ABSTRACT
Swarachakra is a free soft keyboard for Indic scripts on Android devices. This paper presents the design of the Accessible version of Swarachakra keyboard. The layout has been modified in such a way that the alphabets are easily locatable: through tactile reference of edges and haptic markings. Logical ordering of the Indic script characters has been followed. The model uses multi-touch gestures to type a combination of consonant and vowel, and swipe gestures as a shorthand for this selection. Audio and haptic feedback have been used to assist the exploration by touch in order to locate a key on the keyboard. Gesture shortcuts are available for certain keys to enhance the speed of typing. In this paper, we discuss the design of this application which utilizes the existing hardware support and affordances of android smartphones in order to make it accessible. We also mention in brief the outcomes of qualitative evaluation conducted, and the scope of improvement of the application.
