Mental fatigue is a common problem associated with neurological disorders.Until now, ERPA SENS COLD SORES LIP BALM there has not been a method to assess mental fatigue on a continuous scale.Camera-based eye-typing is commonly used for communication by people with severe neurological disorders.

We designed a working memory-based eye-typing experiment with 18 healthy participants, and obtained eye-tracking and typing performance data in addition to their subjective scores on perceived effort for every sentence typed and mental fatigue, to create a model of mental fatigue for eye-typing.The features of the model were the eye-based blink frequency, eye height and baseline-related pupil diameter.We predicted subjective ratings of mental fatigue on a six-point Likert scale, using random forest regression, with 22% lower mean absolute error than using simulations.

When additionally including task difficulty (i.e.the difficulty of the sentences typed) as a feature, the variance explained by the model increased by 9%.

This indicates that task difficulty plays an important role in modelling mental fatigue.The results demonstrate the feasibility of LIP SHIMMER CHERRY objective and non-intrusive measurement of fatigue on a continuous scale.
