Facial temperature as a measure of operator state
TNO Defensie en Veiligheid
We conducted an experiment to explore the relation between facial temperature and mental effort. Participants had to perform mentally demanding tasks while their face was captured with an infrared camera. The temperature of the nose decreased during these tasks and increased during the successive rest blocks. Other parts of the face did not change due to mental effort. The advantage of this workload measure is that it can provide objective and real-time information about mental effort of operators without attaching sensors to an operator. This measure can be used to measure the workload of operators in relatively stable environmental conditions.
De neustemperatuur daalt tijdens de mentale inspanning en stijgt weer tijdens rust
