　　The days of staring attentively at the computer screen pretending to be interested in an assignment even though you are bored out of your mind may soon be coming to an end. That's because if Dr. Harry Witchel has his way, computers of the future will be able to detect boredom and even react to it real-time.

But before you get concerned, the machine is not reading your mind. It is just keeping track of the constant involuntary movements that people exhibit when in front of a computer or even a television. These are not the bigger instrumental actions like moving a mouse or using the remote, but subtle barely noticeable movements like scratching or stretching. Witchel says the level of movement is directly relative to how absorbed the person is in what he/she is reading or watching - the higher the interest level, the lesser the movement!
