Information and communication technologies (ICT) are being considered as one of the most potential medium for bringing more efficient and sustainable solution for many problems faced by different communities belong to the middle of economic pyramid of developing countries. Mobile phone based applications can offer many potential solutions for such problems. Existing solutions which are quite successful at the top of the pyramid user population often prove itself ineffective at the middle of the pyramid naïve low-literate users. In this context interface designers also face considerable challenges due to lack of consolidate icon design methodology which can be adapted for the target user sections. Therefore we propose an empirical study to address the requirement of concrete icon design methodology. Grounded in ‘Cognitive Absorption’ and ‘Theory of Metaphor’ we propose a concrete design guidelines specifically for designing icons to ensure instant learning, usage and adaptation of the system for daily usage. A mobile pest management system is developed to bring the real context on which design methodologies and the role of cognitive absorption and metaphor can be examined to identify the most appropriate one. Our preliminary study suggests a comprehensive icon design methodology and its effect on cognitive absorption as well as behavioral intention for low literate novice users.
