Objective: This study aims to conduct a preliminary study on the changes of attention level and seated postural behavior during sustained cognitive task. Background: Attention is one of the essential element which determines success of the activity. People spend most of their time in a seated posture in their work and strive to maintain a certain level of attention. However, prolonged periods of cognitive activities may decrease attention level. Attention level is widely measured through electroencephalography (EEG) signals, however, such method is costly and demanding. Method: Participants undergo prolonged and different levels of visual cognitive tasks. A pressure mat is used to obtain the real-time center of pressure (COP) data as the measure of body postural sway. Task performance, subjective workload, and postural changes were compared according to period and difficulty of tasks. Results: The results indicate that diminishing of attention is related to the change of postural behavior. In addition, it was founded that task difficulty influences on both postural sway and frequently adopting posture. Conclusion: It was confirmed that there is a potential to detect the attention level of an individual through their seated postural behavior. Application: It is applicable in measuring attention level using pressure sensor as an alternative of EEG.
