Technical framework supporting a cross-device drag-and-drop technique

Abstract

We present the technical framework supporting a cross-device Dragand-Drop technique designed to facilitate interactions involving multiple touchscreen devices. This technique supports users that need to transfer information received or produced on one device to another device which might be more suited to process it. Furthermore, it does not require any additional instrumentation. The technique is a two-handed gesture where one hand is used to suitably align the mobile phone with the larger screen, while the other is used to select and drag an object from one device to the other where it can be applied directly onto a target application. We describe the implementation of the framework that enables spontaneous datatransfer between a mobile device and a desktop computer.
