....action. Many other camera based techniques have been created for human computer interfaces. References [1, 5, 8, 11, 10, 12, 19, 20, 22] explain various face and head tracking techniques previously employed. There are many projects about tracking eye gaze for humancomputer interaction, e.g. [16, 23, 24]. Eyebrow tracking is often used for determining the facial expression of the user [6, 13, 14] Ref. 15] describes a system for detecting and tracking the location of the eyes to create a communication system for computer users with disabilities. Ref. 2] uses facial tracking to emulate a mouse ....

....centroids are attracted to bright portions of the image. Gradient descent is then used to fit the model to images of eyes. Although gaze estimation was not a goal of the paper, one could use the parameters thus derived to estimate the direction of the eye gaze. This template was augmented in [11] to account for eye blinks. This eye model is able to transition between the open and close state according to the given input image to produce the best fit. Trackers have also been built that look for other facial features, like the corners of the mouth, corners of the eyes, and corners of the ....

....positions of facial feature) There is much prior work on detecting and tracking facial features. Many feature extraction methods are based on deformable templates [36] which are dicult to use for real time tracking and have to be initialized properly to achieve a good performance. Tian et al. [29, 30] use multiple state templates to track the facial features. Feature point tracking together with masked edge ltering is used to track the upper facial features. The system requires that templates be manually initialized in the rst frame of the sequence, which prevents it from being automatic. ....

....of these points correspond to the eye corners and the rest are equidistant on the contour. Similarly 3 points are used to describe the shape of an eyebrow. A total of 22 points (8 for eacheye and 3 for eacheyebrow) are used to describe the positions and shapes of upper facial features. Tian et al. [29, 30] use a template that consists of the iris location and two parameterized parabolas, which would t the lower and the upper eyelid. They use the corners of eyes and center points on the eyelids to extract the template parameters. As our system tracks more points than eye corners and center points ....

Many feature extraction methods are based on deformable templates [10] which are difficult to use for real time tracking and have to be initialized properly to achieve a good performance. Tian et al. [8, 9] use multiplestate templates to track the facial features. Feature point tracking together with masked edge filtering is used to track the upper facial features. The system requires that templates be manually initialized in the first frame of the sequence, which prevents it from being automatic. ....

....during a nod or shake are small, fast and jerky all these approaches are either unable to track the head in real time during those movements or the resolution they provide is insufficient to detect head nods and shakes. There is much prior work on detecting and tracking the eyes. Tian et al. [13] use a dual state model to recover eye parameters using feature point tracking of the inner eye corners. This system requires that the eye templates be initialized manually in the first frame of the sequence, which prevents it from being automatic. Many eye feature extraction methods are based on ....

....sequence, the eyelid contours are tracked for open eyes by feature point tracking. For a closed eye, we do not need to track the eyelid contours. A line connects the inner and outer corners of the eye is used as the eye boundary. The detailed eye feature tracking techniques can be found in paper [14]. Brow and cheek features: Features in the brow and cheek areas are also important to facial expression analysis. For the brow and cheek, one state is used respectively, a triangular template with six parameters (x1; y1) x2; y2) and (x3; y3) is used to model the position of brow or cheek. Both ....
