Design and Evaluation of a Cognition Aware File Browser for Users in Rural India

摘要

Among GUI Users throughout the world, the File Browsers are important programs for daily computer use. Making the interface "cognition-aware" results in significant reduction in cognitive load specially for the less technology-aware users while learning and using the interface for file browsing tasks. In this paper we propose SahajBrowser, a special type of cognition-aware, Navigational File Browser for digital technology inexperienced, neo-computer literates in rural India. The novel design of its treeview and abilities to open multiple folders at once, provides more assistance for human cognition and for certain file browsing tasks, performs better than the other widely used Spatial and Navigational file browsers. With a KLM-GOMS model analysis, we will compare 4 browsers of different type and conclude that the design of SahajBrowser is the most time efficient of them all.
