ABSTRACT
Large-screen mobile devices have recently been introduced. While they can display more information on the screen, they have raised the issue of thumb reachability during one-handed use. To solve this problem, we designed four factorial combinations of two triggering techniques (Edge and Large touch) and two selection techniques (Sliding screen and Extendible cursor). A prototype realizing the four interaction techniques was implemented, and a user study was conducted to examine the benefits and problems faced while using these techniques in both portrait and landscape orientations. User study exhibited a significant advantage of Edge triggering with Extendible cursor technique. Also, we collected meaningful comments from the user interview.
