Eye tracking refers to the process that occurs in humans in which a person watches where another person looks. Eye tracking can be regarded as a natural form of behavior in human beings. In the recent past, the notion of eye tracking has received wide usage as a result of the evolution of eye tracking technology. The recent developments in eye tracking have resulted from the need to have an understanding of the behavior of humans, as well as the need to enhance the interaction with computers. In the article, there is an emphasis on the eye tracking process and the various mechanisms involved in eye tracking. As listed, there may be top-down or bottom-up approach to the process of eye tracking. The top-down processes covered in eye tracking include the emphasis on factors such as cultural background, content, as well as education. These factors may interact and have an impact on the bottom-up processes, which tend to emanate from coding of external stimuli by the sensory organs (Holmqvist, Nystro%u0308m, & Andersson, 2011).
In my opinion, the eye tracking topic ought to be covered separately for a number of reasons. The first reason why this topic should be covered separately is because it encompasses a great deal of the interaction between human beings and computers. For instance, eye tracking incorporates the use of an eye tracker, which is a device that emphasizes on sensors, illumination, as well as processing with the aim of tracking gaze and eye movements. Eye tracking should also be covered as a separate topic due to its use of infrared light. The use of this form of light ensures that there is continuous an accurate tracking notwithstanding the light conditions in the surroundings. As a result of these technological interactions, there is a need to study eye tracking as a separate topic. The scope of the topic also calls for its study as a separate topic (Locher, 2006).
The development of eco-feedback systems has resulted from the need to address the concerns regarding the change in the climatic conditions, as well as the rising cost of energy. These systems play a crucial role in saving energy; interface design has an impact on the performance of eco-feedback systems. The numerous advancements and developments in sensor technology and computing have allowed people to have access to the infrastructure, which they occupy and utilize on a daily basis. Eco-feedback interfaces allow people to monitor the conditions from their devices. For example, drivers have the capacity to view the traffic conditions using their mobile devices. In addition, companies have the ability to evaluate the progress of their operations without having to leave their offices. This topic should be studied separately and given a lot of attention since the advancement in technology has significantly changed the interaction between humans and computers (Jain, Taylor & Peschiera, 2011).
The topic of eco-feedback interface should also be studied separately so that students can have an understanding of how energy can be solved. In the current times, any issue dealing with the consumption of energy and climatic conditions should be given a lot of importance. This topic can be regarded as crucial as it enhances innovativeness when it comes to looking for ways, which can be used in the improvement of energy efficiency. This topic related to HCI and as such, HCI professionals ought to know a lot about this topic. The integration of information systems and sensors has allowed the creation of systems, which can be regarded as eco-feedback. The technological changes, which have led to the creation of eco-feedback interfaces, have led to numerous changes in the interaction of humans and computers. This calls for integration of the topic in the education system, as well as knowledge about the topic by HCI professionals (Yolande, 2011).
