AuReTim: an inexpensive and extensible open-source auditory psychomotor vigilance test
AuReTim is a low-cost and extensible open-source portable psychomotor vigilance test (PVT) using auditory stimuli.
It was developed for the standardized evaluation of the non-visual effects of short-wavelength light on the circadian rhythm and alertness within NiviL, a large joint research project, funded by the German Federal Ministry of Education and Research (13N13524, 13N13398). The investigations included people of different ages in different life situations, as well as during illness and stress at different times of the day and over the seasons of the year.
AuReTim shares similarities with the PVT, a neurocognitive assay for sleep loss, which is among the most sensitive tests for sleep restriction and the most practical for use in an operational environment.
AuReTim can be used for field-testing and is based on inexpensive hardware, e.g. its core is a Raspberry Pi leveraging a touch screen as input. Its software is developed in JavaTM using open-source libraries only.
