Abstract
The objectives of this study were to investigate the feasibility of applying computer vision techniques and to analyse changes in behaviour and movement of high school students during class. The study is performed over two phases. Phase one focuses on developing a feasible method to use computer vision-based techniques in high school classes and phase two focuses on the testing of aromatherapy to affect student’s movement. All camera data was processed and analysed by OpenPose, Matlab and EyesWeb. Movement features such as velocity, acceleration, and kinetic energy and postural variables, spinal extension and neck flexion were calculated. Results of phase one, shows significant differences in the overall segment velocity, acceleration, energy, and neck flexion. Similarly, the second phase shows significant differences in velocity, acceleration and jerk for the left shoulder and elbow joints of the group exposed to aroma. In conclusion, the results show the feasibility of using computer vision techniques to apply in a classroom setting.
Highlights
The project “Effect of olfactory stimulation on extending concentration behaviour patterns in high school students” aimed to 1) investigate the effect of aromatherapy with essentials oils on students during the lessons at school 2) examine how presence of aromatherapy affects the quality of movement of the students and 3) application of computer vision techniques for data processing and analysis for comparison of movement behaviour with and without aromatherapy
A further aim is to expand the investigation to different approaches, which will be implemented in the framework of the Project “Effect of olfactory stimulation on extending concentration behaviour patterns in high school students”
As computer vision techniques can detect differences in emotions and behaviours (Camurri, Canepa et al, 2016), we aimed to investigate if similar computer vision techniques, applied to video recordings of an actual classroom in high school, can detect differences in behaviour and movement characteristics of the students
Summary
There were a total of 12 fifty-minute class periods for 3 high school subjects (social science, mathematics, and geography), spread out over 4 days (Class A without aroma during both days (control group) and the Class B without aroma on the first day and with aroma on the second day (experimental group). These preliminary studies allowed us to progress to a series of pilot tests using computer vision techniques applied to subjects during actual high school classes. A further aim is to expand the investigation to different approaches, which will be implemented in the framework of the Project “Effect of olfactory stimulation on extending concentration behaviour patterns in high school students”
