Eye and pen: A new device for studying reading during writing.

We present a new method for studying reading during writing and the relationships between these two activities. The Eye and Pen device makes a synchronous recording of handwriting and eye movements during written composition. It complements existing online methods by providing a fine-grained description of the visual information fixated during pauses as well as during the actual writing act. This device can contribute to the exploration of several research issues, since it can be used to investigate the role of the text produced so far and the documentary sources displayed in the task environment. The study of the engagement of reading during writing should provide important information about the dynamics of writing processes based on visual information.
