Information Technology is evolving at a greater pace and keeps changing even before we get used to the older technology. When the computers were invented, they were large equipments fitting a small store room having a very limited memory, storage space and were very slow in processing even a small amount of data. Since then, they become smaller and more functional with more memory, storage and speed. Technology has reached to a phase when we can surf the internet using smallest of computer like devices Mobile phones and computer help is no more essential to surf the web.

The new age devices such as game consoles these days use motion technology which means we can operate the consoles with our body movement. Computer developers these days have worked on a technology where we can control our computer screen movement with the help of our eye-balls; forget about the touch screen technology. These new developments in information technology signify the death of that humble mouse as we can now use our eye movements in controlling the pointer. The infra red sensor has a great role to play here as it will monitor our eye movements and create 3D images which move the pointer in the direction of our eyes on the computer screen. It means saving time and making things quicker and easier.

There are still some queries and questions about the technical aspects and functionality of this technique which will automatically get answered once this technology is available for all. When you type using MS word and look beyond the computer screen or close the eyes, the infrared sensor will automatically tell you about that. Moving your head in this case is not required as the sensor works only with your eye movement and as your eyes move the sensor will follow it. People still wonder how this technique will work for those wearing specs or lenses and those who are one-eyed. Since the technology is still in the development stage and is not released, it is not fair to comment on these issues as the developers are still working on these aspects and many more as they come up.

Though this technology is going to revolutionize the way we use the computer support, there may not be an alternative to the keyboards as it is still known as the best input device used for keying in huge amount of text and information. If the eye sensing technology starts becoming popular and used extensively, the keyboard will start working in conjunction with our eye movements. There is no alternative available yet for many of the functions which require the help of the keyboard like playing games, zooming-in and out of the pages apart from typing text.
