Cognitive Load, Affect and Stress dataset (CLAS)

The CLAS (Cognitive Load, Affect and Stress) dataset was conceived as a freely-accessible repository purposely developed to support research on the automated assessment of certain states of mind and a person's emotional condition. This resource is intended to support RTD activities aiming at the development of intelligent human-computer interaction (HCI) interfaces that incorporate functionalities allowing for the automated recognition of human emotions, the automated detection of stress conditions, the automated assessment of the degree of concentration, cognitive load, and momentary cognitive capacity, and can account for some personality traits related to the ability to quickly solve logical and mathematical problems under strict time constraints.

The CLAS dataset is available through the IEEEDataPort repository: link

Motion-Capture Dataset in support of Musculoskeletal Disorders research

The Motion-Capture Dataset in support of Musculoskeletal Disorders research (MCD-MSD) can be downloaded here.

The MCD-MSD dataset consists of motion capture data, images, videos, and models, created in an experimental setup that uses the Perception Neuron motion-capture system and the Axis Neuron software tool.  Specifically, in the current research, we consider three main recording scenarios:

∙                 SK – regular working posture when using a standard keyboard;
∙                 EK - regular working posture when using an ergonomic keyboard;
∙                 EKC – correct working posture when using an ergonomic keyboard;
