This paper takes a preliminary look at the direct effects of Motion Induced Interruptions (MIIs) on cognitive performance. Understanding the direct and indirect effects of motion on cognitive performance is becoming increasingly important as crewing limitations and job requirements increase operator workload. In addition, we explored the suitability of mobile tablet technology in motion environments. To do this, participants performed a data logging task using a tablet and traditional pen/paper while experiencing ship motion. MIIs occurred in sea states 4 and 5 on the Beaufort Scale. MIIs had an impact on the number of data transcriptions, but not the accuracy of data transcriptions. Performance accuracy and number of transcriptions were lower when participants used the tablet. The results of this experiment indicate that MIIs should be considered as a form of task distraction that results in increased time on task. As mobile technologies allow for more operator mobility MIIs are likely to become a larger issue. Future research will continue to investigate the impact of MIIs and motion on cognitive task performance. Answering these questions will allow us to offer mitigation strategies with potential implications on operator technology interaction, crewing and operator guidelines.
