Microtasks are small, simple tasks that require human judgment and can be completed independently via the Internet. A series of repetitive microtasks often make up a larger unified project. An example of microtasking could be to identify traffic signs in images, which might be necessary for a project that improves autonomous vehicles. Workers complete tasks on a voluntary basis; in addition to urgent jobs, such as call centers, they choose which jobs to complete and when they complete them.
Some advantages of microworkers include the ability to work from home and the ability to earn extra money in addition to regular jobs. Since microtasks are discreetly contained and do not usually require a high level of specialization, microtasks are available as a valuable source of income for anyone with an Internet connection and computer skills, since they welcome people from different educational, socioeconomic and geographical backgrounds.
