The concept of eye tracking is developing rapidly across various disciplines, and this inspired the current study of using this technology for an educational purpose. Eye tracking is a measuring method to either identify the gaze point or relative motion of the eyes to the head. Researchers at NTNU I Ålesund, have used eye-tracking technology in several projects in the field of maritime human factors, but have not explored its potential to improve the process in manufacturing industries and due to lack of knowledge about the potential of eye tracking technology, its prospect in engineering education was also not investigated. This article provides an overview of usability of eye-tracking technology in engineering education (lean manufacturing course) and manufacturing industries. It presents a hybrid of qualitative and quantitative analysis. A case study performed in the industry to investigate the use of eye tracker in the process improvement of the manufacturing field with the help of smart class environment. This article provides a brief description and discussion of lean and eye-tracking technology as well as its possible applications and limitations.
