| Popis: | 100 The objective of thesis is to present a set techniques integrated into a low-cost eye gaze tracking system. An eye gaze tracking system is a system that can estimate the direction and a position of the human eye gaze. It can be used in medical, military and entertainment. There are several ways of tracking the direction of the eye-gaze by using reflection of light, electro-oculogram (EOG), or contact lens, etc. Each of them has its own advantages and disadvantages such as high complexity, high cost, and invasive way. Price and convenience are two important considerations, and therefore we proposed the theory not just only easy to use but also install a web camera device it can be operated. In this thesis three-stage algorithm is proposed to estimate the eye gaze direction. At the first stage, an efficient face detection based on PCA Feature is employed to locate the user’s face. Then use template matching to detect the human eye. Last, we used horizontal projection and vertical projection to identify where the eye looking at. |
