Abstract

We compared a game-based experiment carried out in the lab with crowdsourced set ups (informed and uninformed participants) on the device’s human resolution (DHR) - the minimum size for dragging the finger onto a target on a touch screen. Lab participants produced fewer errors than the crowd. From lab participants, we found the smallest selectable target width for dragging onto non-occluded targets with visual target position feedback, was between 2mm and 4mm on mobile touch devices. Performance data on error not time allowed for drawing this conclusion as participants from all groups did not take enough care and time to acquire the targets. The bi-modal performance distributions of crowd participants required filtering data.
