Background:

Wearable sensors provide rich physiological data for human activity recognition.
Distinguishing between age groups and cognitive states using physiological signals is challenging.
Controlled experiments are crucial for reliable data acquisition and analysis.

Purpose of the Study:

To develop and validate classifiers for task classification using physiological signals.
To differentiate between young and older adult populations based on physiological responses.
To enable the classification of cognitive load and environmental interaction tasks.

Main Methods:

Acquisition of physiological signals from young and older adults in controlled environments.
Implementation of signal denoising, normalization, and feature extraction techniques.
Development and application of machine learning classifiers for task and age group prediction.

Main Results:

Successful classification of tasks based on cognitive load using physiological signals.
Accurate differentiation between young and older adult populations.
Combined classification of age group and performed task is achievable.

Conclusions:

Physiological signals from wearable sensors are effective for classifying cognitive load and tasks.
The developed methods can distinguish between different age groups.
The study provides a comprehensive workflow and publicly available dataset for research.
