Abstract

In mobile phone soft keyboard layout, some Myanmar characters are behind the keyboard layout scene and it is needed to switch with some control key. For mobile phone text entry system, optimizing the fit between technology and the user is critical for realizing the potential benefits of assistive technology. It is a necessary task to try out the effective key layout design that can enhance the text entry speed. Moreover, there is also weak in analyzing of key layout design for Myanmar Language. The aim of this paper is to develop effective Myanmar soft keyboard layout on mobile touch phone to enhance text entry performance by analyzing the entire possible candidate layout according to their probability statistics. The text entry speeds of currently used Myanmar soft keyboards are also analyzed. The experiment shows that the proposed analytic soft keyboard improves typing performance than conventional soft keyboard on touch screen handheld devices.

Keywords: Soft keyboard, Touch screens, Usability, Human Computer Interaction (HCI).

1 Introduction

Start from the end of 2010, mobile phone market in Myanmar has changed dramatically to touch screen mobile phone. Mobile devices with touch screen capabilities often utilize an on-screen, virtual keyboard, or touch screen keyboard for text input [4]. It replaces the hardware keyboard through on screen character image map [2]. Thus, they can easily be adjusted for different languages and key layouts to achieve effective text entry speed. It is a challenging research area to arrange large number of keys into small handheld device interface for different languages. In personal computer, Myanmar text input is designed to mimic the de facto physical keyboard standard layout – Qwerty (type writer based keyboard).Q
