Empowering Participatory Research in Urban Health: Wearable Biometric and Environmental Sensors for Activity Recognition

Sensors, 2023
Participatory exposure research, which tracks behaviour and assesses exposure to stressors like air pollution, traditionally relies on time-activity diaries. This study introduces a novel approach, employing machine learning (ML) to empower laypersons in

Parameterized Modeling and Recognition of Activities [PDF]

Computer Vision and Image Understanding, 1999
In this paper we consider a class of human activities?atomic activities?which can be represented as a set of measurements over a finite temporal window (e.g., the motion of human body parts during a walking cycle) and which has a relatively small space of variations in performance.
