Abstract

A computer implemented user interface which enables a user to input alphabets in at least one Indian language is disclosed herein. The user interface includes a display enabled keypad layout which in turn includes a default keypad layer, a first keypad layer, a second keypad layer and a third keypad layer. The default keypad layer comprises a plurality of alphabets represented as selectable vowels and consonants. The first keypad layer comprises the vowels and consonants, and a plurality of modifiers. The second keypad layer comprises a plurality of matras, a plurality of halants, the vowels, and the consonants. The third keypad layer comprises the matras and the modifiers. The keypad layers are configured to be incorporated onto the display enabled keypad layout and selectively displayed, based on at least the selection of a key on at least one of the keypad layers.
