Method and System for Providing Optimal Input Layout for Kannada Script

Disclosed is a method and system for providing optimal input layout for Kannada script, a major Indian language is disclosed. The method includes providing a generic layout for inputting Kannada script covering a physical keypad, an on-screen keyboard, a touch screen etc. The method aims at accommodating Live Consonants (Gunitakshara) and Consonant Conjuncts (Samyuktakshara) of the Kannada script as letter-keys while ensuring that the number of keys are kept minimal and are user friendly.

Figure

The figure illustrates an example of an input layout in which a keyboard is provided that optimizes the input layout for Kannada script.

As shown in the figure, the input layout takes into account the grouping of letters in the Kannada alphabet as Vowels (Swara), Structured Consonants (Vargiya Vyanjana), Unstructured Consonants (Avargiya Vyanjana) and Consonantal Diacritics (Yogavaha). This arrangement facilitates a user in locating the keys easily.

The frequently used vowels are placed in the center of the input layout and they are flanked by the consonants and others. Further, a Long Vowel (Dirgha Swara) is obtained by triggering the corresponding Short vowel (Hraswa Swara) key followed by

Ĩౕఘರ್ (Elongate) key. For example, if a user presses (a) followed by Ĩౕఘರ್ (Elongate),

then a (aa) is obtained. Diphthongs (Sandhyakshara), or adjacent vowels such as, (ai) and (au) are accommodated in a single key considering their relatively less usage. Thus, a normal trigger would give (ai) whereas by using the Ĩౕఘರ್ (Elongate) key (au) may be obtained.

In case of Consonantal Diacritics (Yogavaha) such as, ◌ం (Anuswara) and ◌ః (Visarga), the method accommodates them in a single key based on their characteristics. For example, Anuswara is more frequently used than Visarga. Thus, a normal trigger would give Anuswara, whereas by using the Ĩౕఘರ್ (Elongate) key, Visarga may be obtained.

Additionally, by default, the consonants may inherit vowel (a) as per convention.

Since independent vowels do not occur in the middle of a word, the Vowel keys are also used to get corresponding Vowel Signs without additional keys. For example, (ka) followed by (u) would give కు (ku). In the same manner, as the Aspirated Consonants (Mahapra...
