The science behind HUME: AI and stress

What is stress, and what does HUME actually measure?

The stress that HUME measures can be referred to as physiological arousal. For example, this can be physical activity, emotional stress, or excitement. Arousal refers to the body’s state of alertness and readiness to respond, which can be associated with both positive and negative experiences.

Hume collects the following physiological raw data points:

• Heart rate (HR) - the number of times your heart beats per minute

• Electrodermal activity (EDA) - electrical conductivity of the skin, which changes with sweat gland activity

• Interbeat intervals (IBI) - time duration between consecutive heartbeats.

• Movement - whether the client is standing still or moving (to distinguish between physical activity and emotional stress)

How do our systems work: AI and algorithms?

HUME analyses the raw data from those body indicators and, through AI models and algorithms, successfully determines whether a client is stressed (aroused) or not, both at the current time and over longer periods.
