Effects of cognitive consistency in microtask design with only auditory information

Abstract

Microtasks expand ways for people to work, which we could not imagine in the past. When people have pockets of time, they can perform microtasks. This paper pursues this approach further by exploring the design of microtasks that interact with workers with audio and physical means only, without any visual representation. Such a task can be performed in situations where workers cannot use display devices. This paper shows that consistency in navigation is an important factor and proposes a principled framework that develops consistent non-visual microtasks. The experimental results with real-world workers show that the resultant task design allows them to produce better results than tasks without consistency.
