An Exploratory Study on Correlations of Hand Size and Mobile Touch Interactions
Sarah Prange, Daniel Buschek, Florian Alt · 2018
We report on an exploratory study investigating the relationship of users' hand sizes and aspects of their mobile touch interactions. Estimating hand size from interaction could inform, for example, UI adaptation, occlusion-aware UIs, and biometrics. We recorded touch data from 62 participants performing six touch tasks on a smartphone. Our results reveal considerable correlations between hand size and aspects of touch interaction, both for tasks with unrestricted "natural" postures and restricted hand locations. We discuss implications for applications and ideas for future work.
