Abstract
User interface design, as a crucial part of software design, is complex. Current micro task crowd sourcing workflows do not support its complexity well. The difficulty particularly relates to the process to decompose an interface design task into micro tasks. In order to make micro task crowd sourcing more supportive for interface design, we need a workflow that can help task owners to break down interface design tasks more easily. This paper briefly describes three experiments that help inform various aspects of workflow design for interface design through micro task crowd sourcing.
