Abstract:
We present and evaluate dynamic adaptations for mobiletouch GUIs. They mitigate reachability problems that users face whenoperating large smartphones or \phablets" with a single hand. In particular; we enhance common touch GUI elements with three simple animatedlocation and orientation changes (Roll, Bend, Move). Users cantrigger them to move GUI elements within comfortable reach. A labstudy (N=35) with two devices (4.95 in, 5.9 in) shows that these adaptationsimprove reachability on the larger device. They also reduce devicemovements required to reach the targets. Participants perceived adaptedUIs as faster, less exhausting and more comfortable to use than thebaselines. Feedback and video analyses also indicate that participants retaineda safer grip on the device through our adaptations. We concludewith design implications for (adaptive) touch GUIs on large devices. «
