Ambulatory assessment usually refers to the monitoring of physical activity of physiological processes as participants go about their daily life. The objective is to study people in their natural environments not in the lab. This method is becoming more and more popular with the growing availability of wearable sensors.

The Society for Ambulatory Assessment defines it as:

Ambulatory Assessment comprises the use of field methods to assess the ongoing behavior, physiology, experience and environmental aspects of people in naturalistic or unconstrained settings. Ambulatory Assessment uses ecologically-valid tools to understand biopsychosocial processes as they unfold naturally in time and in context.
