How Does Eye-Tracking Technology Work?


Many people are struggling with the use of computers due to repetitive strain injury, which usually occurs due to the uses of the mouse or the touchpad on a laptop base. However, there may be a way around that through sensors tracking your eye to do everything that a mouse would usually do. Rather than drag the pointer to a folder with the touchpad, you are able to look right at the folder and automatically open it.

It will create a better form of game playing on the PC since more people will be able to aim and fire better because they will not have to take into account human error or a slight twitch in their arm. It also means a lot of time is saved through flicking through document pages since the system will be able to do it automatically once you have scrolled to the bottom of the page with a simple look.

Everything will be done in a similar way to the way Microsoft’s Kinect for the Xbox works. There will be infrared sensors placed in the computer, which will track your eye movements. It will do it on a much smaller scale than what the Kinect does – rather than tracking the larger movements of your head or arm, it will track the smaller movements of your eyes. All it will take is a glance or a slight movement on the screen and the computer will be able to pick it up.

The sensors will work through the glint, angle and direction that your eye is looking in; it works with 3D, the way the world seems to be going in. However, that will not stop those who only have one working eye from using it since the developers have found a way to make the sensors take that into account. It can also work with those who wear glasses, so the movement can be seen through the lenses and still pick up correctly, although more development is going into those who have strong prescriptions.

It will be controlled specifically for you and follow a pattern of what you are doing. For example, if you want to keep the text that you are reading at the top of your screen, then the system will pick up on this and do it for you automatically. If you like to highlight what you have read, again the system will pick up on this and do it for you while you read. It also makes the use of searching for the dictionary a lot easier. Stare at a word long enough and you will see the definitely pop up automatically.

The sensors are easy to use and will make using the computer a lot easier and take up much less time than having to use a mouse or touchpad to search for everything on your computer. It will do all of the hard work for you.
