Abstract

We present an empirical study that compares Zoom&Pick (ZP) and Semantic Snarfing (SS) which are techniques for selecting targets on a large display using a mobile device. ZP uses a mobile pointer to zoom-in the region of interest and select the targets on the large display. SS involves pointing at the large display to transfer the zoom-in view of the pointed region onto the mobile touchscreen and make selections thereafter. The experimental results indicate that SS outperforms ZP in terms of speed.
