The study results show that for mobile devices, the two-level adaptive design is expected to give best performance in terms of text entry rate and accuracy. Five two-level VKs representing three design paradigms (alphabetic, frequency-based and adaptive) have been designed and compared in an empirical study. In order to resolve the resulting usability-performance trade-off, this paper proposes a two-level design.
The existing methods cannot be applied directly to Bengali VK design due to the problem of accommodating the large Bengali alphabet (more than 60 characters) on a small display area. However, no such work has been reported for Bengali, the second and fifth most popular language of India and the world, respectively. Several layouts, primarily in English and also in some other languages, have been proposed to achieve the twin objectives. It is important to design VK layouts in a way such that the users can achieve high text entry speed with high accuracy. Virtual keyboards (VK), which allow text to be entered by tapping keys displayed on the screen, are among the predominant mode of text input for such devices. Text entry has become one of the most frequent activities performed using mobile devices such as PDAs.
