Can stress be measured?

For the past few years, Eydís has been looking into it. She did a cross analysis on different measurements of cognitive workload with respect to the Icelandic flight industry. Cognitive workload, for the purposes of this article is synonymous with stress. The research indicates there are clear differences in measurements when an individual is rested or stressed. While the research focused on individuals in the aviation industry, the results can be applied to all people.

So, the answer to “Can stressed be measured?” is yes, most definitively. To get a more in-depth explanation of the indicators of stress, please read Eydís’ PhD thesis here

This research has been done in collaboration with ISAVIA and Icelandair.

Eydís has successfully defended her PhD thesis!

We are pleased to announce that Eydís has successfully defended her PhD thesis on “Cognitive workload classification with psychophysiological signals for monitoring in safety critical situations” on 18th of January. Over the past few years, Eydís has worked on a dissertation studying the effect an increased cognitive workload has on acoustic and cardiovascular signals. She collected data from over 100 participants in a simulated environment, which she analyzed quantitatively and qualitatively. The key contribution of her thesis is in using a signal processing approach and showing that an involuntary response of the cardiovascular system can very accurately reflect one’s mental effort during a task. The thesis is a result of her cooperation with Isavia, and their effort to improve management of people working in an air traffic control environment.

Congratulations Eydís!

Featured in BBC 4 Tech: Cognitive Workload Research

Last fall Michal was interviewed by a broadcast journalist for the BBC Arabic segment, BBC 4 Tech. The interview was regarding some early research he did with the Cognitive workload monitoring using voice project. The BBC 4 Tech segments have been uploaded onto YouTube with voice-overs in Arabic.

Thanks to the BBC team you’ll get the distinct pleasure of seeing one of our own speaking Arabic, albeit dubbed, if you select play:

 

LVL goes to Hungary

In September Eydís will be representing our group at the CogInfoCom 2017 Conference. This will be LVL’s second time at CogInfoCom in Hungary, and we hope it will be an exciting conference with valuable insights. She will be presenting her paper “Cognitive workload classification using cardiovascular measures and dynamic features.” This will be Eydís’ last conference and paper before her study abroad semester starts later this year. So we hope she stays healthy and enjoys her time in Hungary.

 

Article Publication in the Periodica Polytechnica Electrical Engineering and Computer Science journal

At CogInfoCom 2016, Eydís Huld Magnusdottir, gave a great presentation about Monitoring Cognitive Workload Using Vocal Tract and Voice Source Features. It was so informative in fact that the Periodica Polytechnica Electrical Engineering and Computer Science, a great open access journal, has published it. The article has the same name as the conference paper, Monitoring Cognitive Workload Using Vocal Tract and Voice Source Features. Eydís’ article is about the study she did in Iceland involving cognitive workload, Stroop tasks, and nearly 100 participants to find out whether vocal tract features perform better or worse than voice source features.

Pilot tests

The paralinguistic team finished gathering additional data for the Voice patterns in air-traffic control project in the second half of December.  The participants are all pilots working for Icelandair that came to us straight after grueling sessions in their flight simulator.

We want to thank all the participants and staff of Icelandair for their cooperation!
