Such a system which once calibrated does not need limb functions for inputs can be really helpful as an assistive technology for people with limb function disability. Not only does the application use eye movement as the primary source of input it can be used to trigger certain events based on the facial expression of the user. The proof of concept software is built as a web application in HTML, CSS, and JavaScript due to its wide availability and ease of use. In future however, such a system can be fully built as an Operating System specific software for native use. The core of the software uses WebGazer.js and CLMTracker.js for detecting and predicting the gaze of the user. Once such a system is built, it can not only be used on desktops but for Virtual Reality (VR) and Augmented Reality (AR) applications.en
