"Oh Snap" - Helping Users Align Digital Objects on Touch Interfaces

We introduce a new snapping technique, Oh Snap, designed specifically for users of direct touch interfaces. Oh Snap allows users to easily align digital objects with lines or other objects using 1-D or 2-D translation or rotation. Our technique addresses two major drawbacks of existing snapping techniques: they either cause objects to “jump” to snap locations, preventing placement very close to...

A One-Handed Multi-touch Method for 3D Rotations

Rotating 3D objects is a difficult task. We present a new rotation technique based on collision-free “mating” to expedite 3D rotations. It is specifically designed for one-handed interaction on tablets or touchscreens. A user study found that our new technique decreased the time to rotate objects in 3D by more than 60% in situations where objects align. We found similar results when users trans...

idAnimate: A General-Purpose Animation Sketching Tool for Multi-Touch Devices

Creating animations is a complex activity that often requires an expert, especially if results need to be obtained under time pressure. As animations are potentially relevant in many different contexts, it is interesting to allow more people to use them for communicating ideas about time-varying phenomena. Multi-touch devices create opportunities to redesign existing applications and user inter...

Multi-touch for General-purpose Computing: an Examination of Text Entry

Multi - touch is Dead , Long live Multi - touch

Interest in multi-touch interaction with large and small displays surfaces has seen a recent explosion. We describe key moments in " multi-touch's " latest history and rank " multi-touch " in Gartner's five-phase hype cycle. We also (re)highlight the issues that designers have to take into account when designing multi-touch applications on multi-touch sensitive surfaces to address the ensuing p...
