In this work, we explore the design of multi-resolution input on multi-touch devices. We devised a refined zooming technique named Offset, where the target is set at a location offset from the non-dominant hand while the dominant hand controls the direction and magnitude of the expansion. Additionally, we explored the use of non-persistent transformations of the view in our design. A think-aloud study that compared our design to a bimanual widget interaction and the classic pinch-based interaction with a freeform drawing task suggests that Offset offers benefits in terms of performance and degree of control. As well, for the drawing tasks, the transient nature of view transformations appears to impact not only performance, but workflow, focus of interaction, and subjective quality of results by providing a constant overview of the user's task.
