Through increased usage of information technology in research and practice ever more tasks can be automated to make scientific experiments more efficient in terms of cost, speed, accuracy, and flexibility. Scientific workflows have proven useful for the automation of scientific computations. However, not all tasks of an experiment can be automated. Some decisions still need to be made by human users, for instance, decisions how an automated system should proceed in an exceptional situation. To address the need for integration of human users in such automated systems, we propose the concept of Human Communication Flows, which specify the way how an application, such as a scientific workflow, can interact with a human user. We developed a human communication framework that implements these Communication Flows in a pipes-and-filters architecture supporting notifications and request-response interactions. For usage within a scientific workflow we created workflow fragments, which implement the interaction with the framework. Different Communication Services can be plugged into this framework to account for different communication capabilities of human users.
