Limitations Of Eye Tracking Essay

710 Words3 Pages

6. Limits of eye-tracking Eye tracking has a lot of uses and benefits, but we cannot ignore the fact that it also has a few limitations. We are going to analyze some of these possible negative aspects. Below are some of the disadvantages we have observed. i. Eye tracking can be misleading, because it does not capture peripheral vision. Eye tracking records and displays fixations in the small part of our visual field that produces the sharpest vision. It does not record peripheral vision, which makes up 98% of our visual field. This is significant, because we use peripheral vision to choose where to fixate our fovea next. This is why eye tracking visualizations can be misleading. For example, in a heat map, some assume users did not see areas without hot spots at all. It is important to recognize that the eye tracking fixations, or hot spots, do not represent everything …show more content…

Another limitation is that participants need to remain within range of the eye tracker. Though modern systems can track participants’ eyes over a wide range, participants often move out of range over time. When this occurs, the facilitator must ask a participant to move back into range. Each time this happens, it interrupts the participant’s task and disrupts the naturalness of the situation. vii. Eye tracking tests take more time. This is why eye tracking is probably not the best choice for testing with a low budget or when a quick result is needed. viii. Eye tracking is subject to technical problems. ix. The equipment is very expensive and it is also necessary to have a specialized knowledge to work with this tool. It is crucial to have the trained employers who know how to use this technique, and most important of all, there needs to be specialized staff to interpret the results obtained and make conclusions. x. Not all participants fulfill the requirements to work with an eye tracking device. For example, people with contact lenses are not able to take part in these

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.

Follow The Leader: Brain Game Analysis

Brain game season 3 Follow the leader. This episode shows how the brain can be fooled in many ways. The first example that was given was the six colored dots that were moving in a circle, if you focus in one color the dot seems that it is moving up and down in a straight line when in reality the dot is going in a circular motion. This illusion shows how the brain cannot take so much information at once; thus your brain makes you think that all of the color dots are going in the same circular motion.

The active listeners mimicked a person talking on the phone or having a conversation with a passenger in the car (Lewis 3). Both types of subjects had to face a computerized screen that tracked their eye movements. A new object would appear on the screen during the questioning, and the eye-movement speed to the object was recorded. The active listeners took almost one hundred milliseconds longer (Lewis 18). This delay does not seem like much, but it piles on top of eachother; Vecera describes it as a “snowball effect.”

The Importance Of Selective Attention

1055 Words | 5 Pages

Attention has always been a prized commodity. The brain knows it and cognitive psychologists know it, but the average person has yet to fully grasp the concept. Articles on how to multi-task still flag the covers of popular magazines, and distracting cell phones and tablets accompany students to class on the forefront of their desks next their notes. It has been verified time and time again that the mind simply cannot attend to two things simultaneously; one can pay attention to one thing or another, but not to two things at once. People know that neutralizing distractions will yield invaluable minutes of clarity and focus, but for most, the application of such, is nearly impossible.

1061 Words | 5 Pages

Attention is a restricted source; therefore, selective attention permits people to not take notice of insignificant details and concentrate on the main material that matters. Theories of selective attention incline to emphasise on when stimulus information is attended to, either early in the procedure or late.

Strengths And Weaknesses Of Perception Essay

812 Words | 4 Pages

In this essay I will write about the strengths and weaknesses of perception as a way of knowing. Perception is the way we perceive the world through our senses. We use all five of our senses, which are sight, hearing, smell, taste and touch to understand the world and interpret it. We can then say it’s a Primary way of knowledge. We can also say that, because the senses is the way our body communicates, we have at least three more senses: kinesthetic sense, which is our awareness of our body’s dimensions and movement; vestibular sense, which is the awareness of the human’s balance and spacial orientation; and organic sense, which is the manifest of the internal organs (for example, hunger or thirst).

How Does Language Affect Communication

1045 Words | 5 Pages

Eye contact also plays a vital role in effective communication. 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.
