Abstract

Additional input controls such as fingerprint scanners, physical buttons, and Back-of-Device (BoD) touch panels improve the input capabilities on smartphones. While previous work showed the benefits of input beyond the touchscreen, unfavorably designed input controls force detrimental grip changes and increase the likelihood of unintended inputs. Researchers investigated all fingers' comfortable areas to avoid grip changes. However, there is no understanding of unintended BoD inputs which frustrate users and lead to embarrassing mistakes. In this paper, we study the BoD areas in which unintended inputs occur during interaction with the touchscreen. Participants performed common tasks on four smartphones which they held in the prevalent single-handed grip while sitting and walking. We recorded finger movements with a motion capture system and analyzed the unintended inputs. We identified comfortable areas on the back in which no unintended inputs occur and found that the least unintended inputs occurred on 5" devices. We derive three design implications for BoD input to help designers considering reachability and unintended input.

Fingers' Range and Comfortable Area for One-Handed Smartphone Interaction Beyond the Touchscreen
CHI '18: Proceedings of the 2018 CHI Conference on Human Factors in Computing Systems

Previous research and recent smartphone development presented a wide range of input controls beyond the touchscreen. Fingerprint scanners, silent switches, and Back-of-Device (BoD) touch panels offer additional ways to perform input. However, with the ...

Gaze and Touch Interaction on Tablets
UIST '16: Proceedings of the 29th Annual Symposium on User Interface Software and Technology

We explore how gaze can support touch interaction on tablets. When holding the device, the free thumb is normally limited in reach, but can provide an opportunity for indirect touch input. Here we propose gaze and touch input, where touches redirect to ...

fingerT9: leveraging thumb-to-finger interaction for one-handed text entry on smartwatches
SA '17: SIGGRAPH Asia 2017 Mobile Graphics & Interactive Applications

We introduce FingerT9, leveraging the action of thumb-to-finger touching and the surface of the finger segments, to support one-handed text entry on smartwatches. This is achieved by mapping a T9 keyboard layout on the surface of finger segments, ...
