Chapter
Speech Signal Based Measures
This chapter reviews cognitive load measurement methods via speech with typical experiments to induce different cognitive load levels via speech being introduced. Various speech features are then investigated,...
-
Chapter
Mouse Based Measures
This chapter demonstrates the applicability of mouse interactivity based features as indicators of a user’s cognitive load. The chapter begins by introducing some basics of user mouse interaction. Then the tem...

Chapter
Multimodal Measures and Data Fusion
This chapter presents a model for multimodal cognitive load. The features extracted from speech, pen input and GSR in a user study are fused using the AdaBoost boosting algorithm to demonstrate the methods adv...

Chapter
Stress and Cognitive Load
This chapter investigates the effect of stress on cognitive load measurement using GSR as a physiological index of CL. The experiment utilises feelings of lack of control, task failure and social-evaluation to...

Chapter
Dynamic Cognitive Load Adjustments in a Feedback Loop
This chapter presents a cognitive load adaptation model that dynamically adjusts workload during human-machine interaction, in order to keep the task demands at an appropriate level. Physiological signals such...

Chapter
Linguistic Feature-Based Measures
This chapter discusses methods for cognitive load examination via language and shows that many features, some of which were originally designed to examine language complexity for learning analytics or comprehe...
-
Chapter
Pen Input Based Measures
This chapter introduces methods to examine cognitive load via writing and pen-based features, including writing velocity, pen pressure, writing gestures and additional features derived from these signals. Base...

Chapter
Emotion and Cognitive Load
This chapter investigates pupillary response and GSR as a cognitive load measure under the influence of such confounding factors. A video-based eye tracker is used to record pupillary response and GSR is recor...

Chapter
Galvanic Skin Response-Based Measures
This chapter focuses on the use of Galvanic Skin Response (GSR) for cognitive load measurement. GSR is a measure of conductivity of human skin, and provides an indication of changes within the human sympatheti...
