Lying in bed on a very cold Auckland night, reading a 50 page document on an iPad made me realise how handy it would be if I could scroll down or up a page by using my eyes. Its not fun if you have to take out your hand from under a warm blanket every time you have move down or up the page! This type of user interface (UI) would also be a boon for disabled computer users.
Well it looks like there is quite a lot of movement in the research area on eye-movement-based user interfaces. An alternative to the computer mouse is one example. Another is Tobii Eye Tracking Research. Looks like I might not have to wait long before I can enjoy the warmth of my bed while reading on a tablet or computer while my hands stay warm.
