The touchscreen has been the dominant input surface for smartphones and smartwatches.
However, its small size compared to a phone limits the richness of the input gestures that …

Smartphones are the most successful mobile devices and offer intuitive interaction through
touchscreens. Current devices treat all fingers equally and only sense touch contacts on the …

Current interactions on a smartwatch are generally limited to a tiny touchscreen, physical
buttons or knobs, and speech. We present WatchOut, a suite of interaction techniques that …

When people hold their smartphone in landscape orientation, they use their thumbs for input
on the frontal touchscreen, while their remaining fingers rest on the back of the device (BoD) …

Previous research proposed a wide range of interaction methods and use cases based on
the previously unused back side and edge of a smartphone. Common approaches to …

Back-of-device interaction is a promising approach to interacting on smartphones. In this
paper, we create a back-of-device command and text input technique called BackSwipe …

Motion gestures can be expressive, fast to access and perform, and facilitated by ubiquitous
inertial sensors. However, implementing a gesture recognizer requires substantial …

The handedness (ie the side of the holding and operating hand) is an important contextual
information to optimise the one-handed smartphone interaction. In this paper, we present a …

We present Vidgets, a family of mechanical widgets, specifically push buttons and rotary
knobs that augment mobile devices with tangible user interfaces. When these widgets are …

Back-of-device (BoD) interaction using current smartphone sensors (eg accelerometer,
microphone, or gyroscope) has recently emerged as a promising novel input modality …
