researchers General personal use Scientists and researchers experimented with people and computers. A certain number of volunteers were gathered to test out if computers could function by interpreting what the individual was physically doing without actually having to touch the computer itself. In this specific experiment researchers asked the volunteers to try to control the computer using nothing but their eye movement. The science behind this involves the use of electrooculography, also referred to as EOG. This is basically a technique used to examine someones eye movements. This is then made into a cursor on the computer screen for the individual, in this case the volunteers. The volunteers were then shown a display on the computer screen of the letters in the alphabet. With their eye movements, the volunteers were now able to use this cursor on the computer screen and perform tasks such as typing words. Security purposes in busy and overcrowded areas An example of the applied version of this computer technology is controlling the safety of people in heavily populated areas such as bus terminals, airports or even shopping complexes. To monitor such places you definitely need a security camera at the site itself. However, researchers are trying to make use of computers to manage such areas aside from just video cameras alone. Basically a video stream is evaluated and examined which involves a bit of math, for example a description of shapes, the flow of people and their movements. Then that data is analyzed in terms of crowd density, their pace and the direction in which they are moving. At last is when the use of the computer comes in. The computer aids in evaluating any type of activity in these types of crowded areas that seems fairly irregular. The information that the computer gives will help provide an alert or warning that something is not going the way it should. In the example of a mall, this sort of computer will provide an alert to something like an individual that has fallen from an escalator. Marketing purposes Helping businesses and local stores analyze how their customers behave while shopping is another example of how this type of computer technology will be implemented. The scientists and researchers that are creating a computer that runs on this type of technology are making use of the idea of body language being used to work with computers for reasons
