Eye gaze controlled mouse pointer
Course projectGuide : Prof. Prithwijit Guha, IIT GuwahatiJul’ 15 - Nov’ 15Eye gaze controlled mouse pointer
Developed a robust eye gaze controlled mouse pointer system using a webcam. The algorithm for gaze tracking used Viola-Jones algorithm for face detection, K-means clustering for thresholding and gradient descent for finding the pupil location. Similarity of triangles was used for mapping pupil movement to cursor movement.
