7. The computer implemented method of claim 6 , further comprising processing and transforming said generated modal output in said text mode into said modal output in said audio mode by said multimodal communication assist application by associating said generated modal output in said text mode with one or more audio elements stored in said database to generate said modal output in said audio mode, wherein said multimodal communication assist application renders said generated modal output in said text mode and said audio mode to said user via said interactive interface for assisting said user to learn and/or communicate in said visual communication language.
6. The computer implemented method of claim 1 , wherein said processing and said transformation of said captured modal input in a visual mode of said modes received from an input device into said modal output in a text mode and/or an audio mode of said modes by said multimodal communication assist application comprises: detecting and extracting one or more visual elements from said captured modal input in said visual mode based on said characteristic information of said user; scaling said extracted one or more visual elements to a predetermined scale; segmenting each of said scaled one or more visual elements into a predetermined number of blocks; determining a numerical descriptor for said each of said scaled one or more visual elements based on number of highlighted visual constituents in each of said predetermined number of said blocks; recognizing a gesture from a plurality of gestures stored in a database maintained by said multimodal communication assist application based on said determined numerical descriptor; and associating said recognized gesture with one or more text elements and/or one or more audio elements stored in said database to generate said modal output in said text mode and/or said audio mode respectively, that corresponds to said captured modal input in said visual mode, wherein said multimodal communication assist application renders said generated modal output in said text mode and/or said audio mode to said user via said interactive interface for assisting said user to learn and/or communicate in said visual communication language.
