Figure: Gamification elements of the interface (section 3.1)

[manaswisaha]

Image highlighting three gamification elements of the interface:

1. Mission start screen (to highlight how the system divides tasks into small chunks)
2. Mission completion screen (to highlight how users can review their contributions in the current mission in terms of labels and routes, past contributions in terms of audited streets, and track their personal progress to complete the current neighborhood)
3. [maybe] (i) instructional messages shown in the first mission ("now turn to review the instructions....") or, messages shown to make the user a power user (e.g. use keyboard shortcuts for labeling, zooming, and marking labels)
   OR
   (ii) Tooltip guide to help users assess severity (the small images shown when hovering over the severity scale)

Ideas welcome for the 3rd element.
