Abstract

It is common to use modifier keys in a PC environment in order to change drag modes, but mobile devices with a touch screen do not provide this option. Thus, we present ForceDrag to address this issue, which is a touch drag operation where pressure is used as a modifier key to change touch drag modes. We also introduce the concept of force lock and we compare three selection techniques for performing a force lock in a user study. We also describe a prototype implementation and discuss early user feedback on ForceDrag.
