Abstract-The system is a human computer interface for mouse operations using face. System serves as an intermediate block between the users and computer. It will capture the desired feature with a webcam and monitor its action in order to translate it to some events that communicate with the computer. While different devices were used in HCI (e.g. infrared cameras, sensors, Microphones) .There are various technique to implement a system that track the human eyes. In this paper we provide a new way to implement gaze estimation on the basis of Eye touch system. The least-square-algorithm is used to determine the gaze direction. The system also use a effective pattern classification algorithm to perform different operations of mouse such as left , right and double …show more content…

There are many approaches to find accurate estimation of Gaze. There is a popular technique to solve this problem is electro-oculography [5]-[9].In this technique the sensors are used i.e electrodes. sensor is for collecting the information about position of eyeball.
Another approach is first track the face and then detect and track the eyes [].There is Feature based and Image based method to detect he face. In the feature based method, finding the facial feature such as nose, eyes brows, eyes pupil and lips. In image based method there is scanning of image which looks like face. In Eye detection there is a Regression approach, Bayesian approach [].
There is also webcam based eye detection approach. In this technique the mean gradient vector algorithm is used to detect the eye ball center. This method is not so accurate [].

Software and Hardware:

  • Hit A Baseball Research Paper

    706 Words  | 3 Pages

    Major League Baseball batters have roughly 0.40 seconds to determine what type of pitch the pitch is, determine if the pitch is a ball or strike, determine the speed of the pitch, finish their stride and put their foot down, and attempt to successfully hit the ball. Keeping their eye on the ball makes these tasks more simple. Hitting a baseball is a complex task and one’s vision plays a big part in whether or not they can hit the ball. Although one does not need 20/20 vision to hit the ball they do need to keep sharp focus on the ball in order to hit the ball. Keeping their undivided attention on the ball helps the player see the rotation, and see where the ball is going in order to hit it.

Instead of requiring people to place their hand on a reader (a process not acceptable in some cultures as well as being a source of illness transfer) or precisely position their eye in front of a scanner, face recognition systems unobtrusively take pictures of people 's faces as they enter a defined area. There is no intrusion or delay, and in most cases the subjects are entirely unaware of the process. They do not feel "under surveillance" or that their privacy has been invaded.

There are times when we experience words that come out of our mouth and the ways we communicate through our body language are totally different. In this kind of situation, the receiver has to determine whether to believe verbal or nonverbal message. Regularly the receiver would select the nonverbal as it is more natural and it truly displays the speaker’s true feeling and intention. The gestures such as the way we sit, how fast and how loud we talk and how much eye contact we make send strong messages to the receiver.
