Psychomotor Vigilance Task Evaluation for Touchscreen DevicesThe Psychomotor Vigilance Task (PVT) is considered the gold standard fatigue detection device and is used frequently in fatigue research. The purpose of this study was to compare a psychomotor vigilance task developed for use on touchscreen devices with the original PVT-192 in conditions of acute sleep loss and circadian desynchronization. Participants arrived in the lab approximately two hours after their habitual time and were asked to stay awake for up to 24 hrs and take 5-minute reaction time tests every 2 hours on two different devices: the original PVT-192 and NASA-PVT on an iPod. We found that the NASA-PVT and PVT-192 were sensitive to the 24 hrs of extended wakefulness.
