A reduction for fat-finger problem on smartphone website using Magnifier with pressure sensing

Abstract

In recent years, with the spread of smartphones, many people use smartphones every day. In many cases, a smartphone is operated using a touch UI, but a Fat-Finger problem occurs in which an adjacent touch UI is erroneously pressed. In addition, various Fat-Finger issues have been studied, and there have been many studies on smartphone software keyboards and smart watches, but few studies on smartphone websites. This study uses a magnifier and pressure detection on a smartphone website, solves the Fat-Finger problem, and proposes a magnifier that is easier to handle than existing magnifiers.
