How do you get me to take out my phone and take a measurement to you? The answer is “nobody knows”. The field is still very young with most literature describing pilot studies with only preliminary findings.
- Examining Micro-Payments for Participatory Sensing Data Collections. Pilot study with 55 participants at UCLA. The task was to take photos of outdoor waste bins. The incentives compared included low, medium, and high levels of payment per photo, single large payment for participation, as well as competition-based payments. The competition-based scheme was most effective in the experiment.
Exploring Micro-Incentive Strategies for Participant Compensation in High-Burden Studies 36 participants. 3 payment schemes. Compenstion per microtask is respectively (i) constant (ii) variable and (iii) random and unknown until completion.
- Enhancing Motivation in a Mobile Participatory Sensing Project through Gaming. Pilot study with 50 volunteers at UCLA indicates that game features of an app. Points were awarded for a search-and-discover game.
Interest in the cause
- Phenology and Citizen Science. Anecdotal evidence that people are motivated by knowing that the data they collect will be used.
