Interaction assessment through physiological interfaces in collaborative & mobile environments

1. Motivation The evaluation stage of the design process of a system is of utmost importance for it to prevail. In recent years, we have witnessed a rise in the adoption of physiological interfaces as a complement to other interaction modalities. These novel interaction modalities are capable of detecting an individual’s biological signals and use that data to interact with a system, covering domains such as arts, entertainment or sports. Despite the existence of some validated work in this area, it mostly focuses individual and laboratorial environments, failing to not only explore the possibilities and challenges of other scenarios but also to mimic the conditions found in the real world. Among these scenarios are collaborative and mobile environments. The increase in the number of participants, the more complex communication channels and data management are some of the issues present in collaborative settings; on the other hand, crowded environments, influential environment variables and the mobility factor are challenges present in mobile environments. The influence of all these aspects in an individual’s biological traits is yet to be addressed in existing work.
