Sleep deprivation may cause accidents, and it has deteriorating effects on health. A measurement of postural steadiness by a portable and affordable Nintendo Wii Fit balance board can be used to quantify a person's alertness. At work, people are under the influence of their environment-often other people-that may affect their alertness. This work investigates whether sleep deprivation among people is "contagious," as quantified by sway measures. We measured 21 volunteers' postural steadiness while alert and sleep deprived. During the measurements, a screen placed in front of the participants showed a footage of either alert or sleep-deprived faces. We found a significant difference between the day time and night time steadiness, but found no effect resulting from watching footage of sleep-deprived people. This finding shows that a posturographic sleepiness tester quantifies physiological sleep deprivation, and is insensitive to the influence of social factors.
睡眠不足可能会导致事故，并且对健康有恶化影响。使用便携式且价格实惠的任天堂Wii Fit平衡板来测量姿势稳定性，可用于量化一个人的警觉性。在工作中，人们会受到其环境（通常是其他人）的影响，这可能会影响他们的警觉性。这项研究调查了人群中的睡眠不足是否具有“传染性”，并通过摇摆测量来量化。我们测量了21名志愿者在警觉和睡眠不足状态下的姿势稳定性。在测量过程中，放置在参与者面前的屏幕展示了警觉或睡眠不足的面部视频。我们发现白天和夜间的稳定性存在显著差异，但观看睡眠不足人群的视频并未产生影响。这一发现表明，姿势描记法嗜睡测试仪可量化生理性睡眠不足，并且对社会因素的影响不敏感。
