CoGMI: Coordinated gestures for one-handed mobile interaction

Abstract

Interacting with touch screen mobiles using thumb is nowadays becoming a common practice. Techniques have been developed to provide the ease of use in interacting with touch screen using thumb. These techniques were rather inefficient in terms of time and error. We propose a model CoGMI which describes an interaction technique which that is the combination of coordinated gestures (drag gestures) and direct touch. The proposed model could be helpful in minimizing the issues such as 1) distant targets reach, 2) the selection of distant targets, 3) accidental selection of targets, 4) occlusion, and 5) accuracy.
