Feature Extraction and Selection for Inferring User Engagement in an HCI Environment

摘要

In this paper, we present our work towards estimating the engagement of a person to the displayed information of a computer monitor. Deciding whether a user is attentive or not, and frustrated or not, helps adapting the displayed information of a computer in special environments, such as e-learning. The aim of the current work is the development of a method that can work user-independently, without necessitating special lighting conditions and with only requirements in terms of hardware, a computer and a web-camera.
