Stress, Mental Workload, Task Difficulty

eye-blink

21 September 2023

Continuous assessment of stress, mental workload and task difficulty is essential in improving the usability and accessibility of interactive systems. Physiological sensing capabilities have often been investigated to achieve this ability, with reports on the limited role of standard physiological metrics. In this project, we explore new approaches to the analysis of our physiological responses for automated estimation of such psychological states.
