The truth - in black and white

Researchers at Haifa University in Israel have been using a computerised writing tablet in an attempt to develop a handwriting equivalent of the lie detector. The tablet measures aspects of handwriting that are difficult to consciously control such as the length of time that the pen is on the paper as opposed to in the air, the length, height and width of each writing stroke and the pressure of the pen on the writing surface. They found that these characteristics differ when people write a deceptive sentence compared to a truthful one. They hope that the handwriting test might provide a cheaper, less intrusive version of the traditional lie detector.
