Keyboard or keypad layout is one of the important factors to increase user text input speed especially on limited keypad such as mobile phones. This paper introduces novel key mapping method "Positional Mapping" (PM) for phonetic scripts such as Myanmar language based on its characters writing positions. Our approach has made key mapping for Myanmar language very simple and easier to memorize. We have developed positional mapping text input prototypes for mobile phone keypad, PDA, customizable keyboard DX1 input system and dual-joystick game pad, and conducted user studies for each prototype. Evaluation was made based on users' actual typing speed of our four PM prototypes, and it has proved that first time users can type at appropriate average typing speeds (i.e. 3min 47sec with DX1, 4min 42sec with mobile phone prototype, 4min 26sec with PDA and 5min 30sec with Dual Joystick Game Pad) to finish short Myanmar SMS message of 6 sentences. Positional Mapping can be extended to other phonetic scripts, which we present with a Bangla mobile phone prototype in this paper.
