Accessibility maps enable impaired/elderly people to move around more smoothly and with less risk. However, very few examples satisfy both the accuracy and coverage requirements, owing to the high cost of physically auditing everchanging roads and pathways. Although crowdsourcing approaches can ostensibly solve this problem, existing studies have relied on volunteers with free time and high motivation.

To address this issue, we propose a crowdsourcing platform for constructing accessibility maps to support four participation modes: Reporter for people having plenty of free time and high motivation; Gaming reporter for people having plenty of free time but with low motivation; Walker for people lacking enough free time but with high motivation; and Gaming walker for people lacking enough free time and with low motivation. This design allows people to select a suitable participation method, depending on their time and motivation.
