Mobile crowd-sensing - Yenra
Announced December 22, 2015, researchers from the UK used data from a research project at Dartmouth College called StudentLife. It includes information on participants' location taken from raw GPS data, which helps determine whether they are working or socializing. Also included is data on activity levels, like running, walking or travelling on public transport, inferred from participants' raw accelerometer data.
They found that exercising and spending time outside the home and working environment have a positive effect on participants' stress levels. By contrast, they found that reduced working hours only slightly impact stress.
