A Comparison of Gamified HCI Studies with Lab and Crowd Participants
Journal Title: EAI Endorsed Transactions on Creative Technologies - Year 2017, Vol 4, Issue 11
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.

Eye-tracking Data, Complex Networks and Rough Sets: an Attempt Toward Combining Them
Eye-tracking sequences can be considered in terms of complex networks. On the basis of complex network representation of eye-tracking data, we define a measure, derived from rough set theory, for assessing the cohesion o...
