Case Study: Eye Movement Based Human Computer Interaction

1990 Words8 Pages

The study entitled Eye Movement Based Human Computer Interaction by R. Fatima, A. Usmani, Z. Zaheer (2016) stated that Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. It can be carried out by the use of eye trackers. Many techniques are available for tracking the movement of the eye; while none is perfect, some are considerable more suitable for user computer interaction than others.

The central problem in the development of eye-gaze interfaces is the so-called Midas touch problem (Jacob, 1995). If a gaze-directed interface is realized straightforwardly then each fixation on an interface element will lead to its activation even when the user has no such intention.

Two approaches to the solution of this problem have been proposed. One is to use an explicit movement as an indicator of user’s intention to issue a command. Gaze is used to select but not to activate an interface control. A typical example is to use voluntary blinks as …show more content…

People are having very little knowledge about the home appliances. They used to contact to the service providers or vendors for solutions. But many times, the problem is very minor and still it consumes both money and time because of lack of knowledge among people about home appliance.

They stated the real problem in using home appliances is that people do not have enough knowledge in using specific appliances, they always end up contacting service providers seeking for solution. Expert systems are derived from the field of artificial intelligence (AI). These are the intelligent computer, which takes decision like human being and perform work like a thought process of human. Like human it also changes or dynamically updates its behavior by new knowledge and learning's. Therefore, it is also known to be an intelligent computer
