Measurement Tool

Studies will have to use wearable devices. Wearable devices may use any combination of electronic or spring-levered uni- or multiaxial accelerometer, gyroscope, magnetometer, or barometer. Other measurement tools such as heart rate monitor and thermometer will be not considered. Wearable devices have to be attached to the body, for example, belt clip or any other assistive accessory. Measurement tools can also be placed in a pocket or in a bag.
