Positional Mapping multi-tap for Myanmar language

This paper is an attempt to enable a practical and efficient composing of message text with Myanmar language on a mobile phone. In this paper, we propose a new idea of key mapping (Positional Mapping) for Myanmar language. Positional Mapping is the key mapping idea for mobile phones based on Myanmar language characters writing positions. We compared our new mapping idea with our proposed Multi-tap keypad layout in terms of key strokes and users tapping speed. Although key strokes requirement for typing Myanmar consonants in Positional Mapping is higher, average tapping speed is 22.5% faster than Multi-tap model. And we can also prove that our Positional Mapping idea is simple and easier to memorize for users from the user studies. Our Positional Mapping idea can be applied not only to Myanmar language but also to other similar phonetic based languages such as Khamer, Thai, Hindi and Bangla etc.
