Multimodal systems, incorporating more natural input modalities
\nlike speech, hand gesture, facial expression etc., can make humancomputer-
\ninteraction more intuitive by drawing inspiration from
\nspontaneous human-human-interaction. We present here a
\nmultimodal input device for Indic scripts called the Voice Key
\nBoard (VKB) which offers a simpler and more intuitive method
\nfor input of Indic scripts. VKB exploits the syllabic nature of Indic
\nlanguage scripts and exploits the user\u2019s mental model of Indic
\nscripts wherein a base consonant character is modified by
\ndifferent vowel ligatures to represent the actual syllabic character.
\nWe also present a user evaluation result for VKB comparing it
\nwith the most common input method for the Devanagari script,
\nthe InScript keyboard. The results indicate a strong user
\npreference for VKB in terms of input speed and learnability.
\nThough VKB starts with a higher user error rate compared to
\nInScript, the error rate drops by 55% by the end of the
\nexperiment, and the input speed of VKB is found to be 81% higher
\nthan InScript. Our user study results point to interesting research
\ndirections for the use of multiple natural modalities for Indic text
\ninput.<\/p>\n","protected":false},"excerpt":{"rendered":"
