Fatigue is a physiological state of reduced mental or physical performance capability resulting from sleep loss or extended wakefulness, circadian phase, or workload. Operators’ fatigue is a major safety concern in transportation. Results of a recent research paper showed that alterations in the acoustical characteristics of voice occur after moderate cumulative sleep deprivation. As a follow-up, NLR wants to extend this research in the field of air traffic control.
The objective of the research is to determine if fatigue resulting from moderate cumulative sleep deprivation and circadian influences is associated with speech audio parameters and whether we could measure fatigue in an operational setting (i.e. handling air traffic). Using speech analysis for measuring fatigue potentially offers several advantages (i.e. non-obtrusive, inexpensive, large scale).Therefore NLR plans to execute an experiment in which sleep deprivation and circadian phases will be varied and a combination of fatigue/alertness measures (incl. speech volume and pitch) will be measured. As an intern you will design and execute an experiment and report about the results. A brief literature survey will be part of the report.
Tasks to be foreseen
- Execute a small literature study
- Desk (and field) research on how to measure speech volume and pitch (incl. which specific measurement equipment)
- Design and execute an experiment in which fatigue/alertness and speech volume and pitch will be measured in a simulated air traffic control setting
- Analyse data
- Report, including suggestions for next steps
- Present the outcome of the study to the department at NLR
This fulltime internship starts November 1st (earlier is possible) and the duration of this assignment will be 5 to 6 months (longer is possible).
- MSc student in Cognitive Psychology or equivalent
- Interest in the area of measuring operator performance, more specifically fatigue
- Good communication and writing skills
What do we offer?
- An inspiring high-tech aerospace-oriented working environment
- An informal culture with room for personal initiative
- You will receive a compensation for general expenditures
NLR is a leading international research centre for aerospace. Its mission is to make air transport safer, more efficient, more effective and more sustainable. Bolstered by its multidisciplinary expertise and unrivalled research facilities, NLR provides innovative and comprehensive solutions to the complex challenges of the aerospace sector. NLR’s operator performance group has a wide range of both academic and practical knowledge on operator performance and human factors (HF) in complex environments. Operator-in-the-loop studies are performed to measure the manner in which personnel conduct themselves in an operational setting (either simulated or realistic). The assessment includes operator performance aspects such as (crew) workload, (team) situation awareness, usability, visual perception, vigilance, and (eye) fatigue. Data is gathered objectively (e.g. heart rate and eye-tracking) and subjectively (e.g. through interviews, workshops and questionnaires).
