“…A viable option is to use a video camera to record the sessions for later coding. There is an increasing amount of work using cameras as the main sensor placed at a certain distance from the child to automatically recognise their behaviour with computer vision (CV) methods (Dawson et al, 2018; Hashemi et al, 2014, 2015; Manner, Jiang, Zhao, Gini, & Elison, 2017).
