Using the it, a test subject can learn to use the BCI to move a cursor (represented by a horizontal bar) on a computer display by imagining hand or foot movements.
This approach is based on the fact that imagery of the movement of different limbs causes changes in oscillatory EEG activity over sensorimotor areas of the cerebral.
Previous model-based eye-tracking methods using low-resolution eye-images face the difficulty of estimating detailed eye-model parameters. The low-resolution eye-images are too coarse to determine the position of the pupil contour in the image.
Figure 1 (a) shows an example of part of a low-resolution eye-image, especially around the pupil contour. Over different quality contents of FVV, the participants eye-tracker recorded spatio-temporal gaze-data indicate more concentrated eye-traversing approach for relatively better quality.
Thus, we calculate the Length, Angle, Pupil-size, and Gaze-duration features from the recorded gaze : Pallab Kanti Podder, Manoranjan Paul, M. Manzur Murshed. Noninvasive Corneal Image-Based Gaze Measurement System.

Body language refers to the nonverbal signals that we use to communicate. According to experts, these nonverbal signals make up a huge part of daily communication.
From our facial expressions to our body movements, the things we don't say can still convey volumes of information. It has been suggested that body language may account for between 60 percent to 65 percent of all communication.
An Interactive Model-Based Environment for Eye-Movement Protocol Analysis and Visualization Dario D. Salvucci Nissan Cambridge Basic Research Four Cambridge Center Cambridge, MA USA +1 [email protected] ABSTRACT This paper describes EyeTracer, an interactive environment for manipulating, viewing, and analyzing eye-movement protocols.
Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head.
An eye tracker is a device for measuring eye positions and eye trackers are used in research on the visual system, in psychology, in psycholinguistics, marketing, as an input device for human-computer interaction, and in product design.
The volume's nine papers specifically report on topics such as sensor confidence, low level feature extraction schemes, non-parametric multi-scale curve smoothing, integration of geometric and non-geometric attributes for object recognition, design criteria for a four degree-of-freedom robot head, a real-time vision system based on control of.

For such an analysis, the graph of the eye's trajectory is covered by boxes of a linear dimension of Δ = 1 lattice unit (Fig. 6 A).
