Abstract EN
A novel second-order entropy-based oculometric, mobile transition matrix entropy (MTME), is presented for use in mobile eye tracking. Our approach calculates the MTME on the spheric gaze transition matrix, which is based on a sphere around each individual divided into equal-size plates (areas-of-interest). This approach allows for the correction of gaze location by head and body movements. Additionally, we demonstrate that the present approach is suitable for the calculation of eye movement entropy in real-time which opens the possibilities for use in human-computer interaction based on users’ attention characteristics. We provide empirical evidence from a collaborative task focused on climate change mitigation, demonstrating that MTME effectively captures collaboration dynamics by differentiating between interaction phases and video viewing. The paper presents the method’s details and discusses the metric’s sensitivity and analytical utility.
