Tap, swipe, or move: attentional demands for distracted smartphone input
TL;DR: It is shown that motion gestures result in significantly less time looking at the smartphone during walking than does tapping on the screen, even with interfaces optimized for eyes-free input, and there may be benefits to making use of motion gestures as a modality for distracted input on smartphones.

Grip Change as an Information Side Channel for Mobile Touch Interaction
Matei Negulescu,Joanna McGrenere +1 more
TL;DR: It is shown that grip change detected using standard mobile motion sensors produces similar in the air touch point predictions to techniques that use auxiliary sensor arrays, even in varying physical scenarios such as interacting in a moving vehicle.
Proceedings ArticleDOI
A recognition safety net: bi-level threshold recognition for mobile motion gestures
TL;DR: This work presents a bi-level threshold recognition technique designed to lower the rate of recognition failures by accepting either a tightly thresholded gesture or two consecutive possible gestures recognized by a relaxed model.

Systems and methods for transferring images and information from a mobile computing device to a computer monitor for display
Yang Li,Matei Negulescu +1 more
TL;DR: In this paper, the authors present a method for transferring images and information from a mobile computing device to a computer monitor for display. But the method requires the user to send a unique code to the remote client, and receive, from the mobile device, a display image for presentation on the remote display.

ZoomPointing revisited: supporting mixed-resolution gesturing on interactive surfaces
TL;DR: This work 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.
