Although there have been many applications related to estimating the state of the eye, this is an issue that is still of interest to researchers because of the variety of data and applications. Various methods have been proposed and are divided into two main groups: direct and indirect.
As for the direct method, which is performed by attaching a device around the eye to record the changes in eye movements, this method has high accuracy, but is difficult to implement in practice because of the inconvenient when having to attach additional sensors around the eyes |
