Free-living conditions
Volunteers were asked to perform several activities such as walking at different paces, running, sitting, standing still or taking public transportation for about 1h30 They wore 3 research sensors that estimated energy expenditure: Fitmate, Armband and Actiheart. They also wore smartphones (in front pant pockets) that collected accelerometry data.
Volunteers were asked to wear sensors during about 12 hours, one day. They wore 2 research sensors that estimated energy expenditure: Armband and Actiheart. They also wore smartphones (in front pant pockets) that collected accelerometry data.
