Abstract
We compared a game-based experiment carried out in a lab study to crowdsourced set ups (both uninformed and informed). We investigated the device’s human resolution - the minimum size for dragging the finger onto a target on a touch screen. Participants in the lab consistently produced fewer errors than those from the crowd. For lab participants, errors significantly increased between targets of 4 mm and 2 mm in width. The uninformed crowd had too many errors to determine significant differences but the informed crowd yielded useful data and performance declined already for targets between 8 mm and 4 mm width. The smallest selectable target width for dragging for all three groups combined, was between 2 mm and 4 mm on mobile touch devices.
