Investigation of transferring touch events for controlling a mobile device with a large Touchscreen

Abstract

When users hold large mobile devices equipped with a large touchscreen in one hand, the region distant from the thumb is too distant for users to control. This forces users to change their hand posture so that their thumb can reach to the top half. To address this problem, we explore a technique that transfers touch events on the bottom half of a touchscreen to its top half. This technique may allow users to control all regions of a large touchscreen by using only the bottom half. Thus, users can control a mobile device without changing hand posture. We conducted a user study to investigate the feasibility of our technique. From the results, our technique is marginally faster than direct touch and thus, might be feasible.
