Researchers at Brigham Young University under the guidance of Professor Jeffrey Jenkins claim they have found an accurate way to determine whether a person is angry or not by analyzing his or her computer mouse movements. People experiencing anger and other negative emotions become less exact in their mouse movements and move the cursor at different speeds. The researchers reached other conclusions but additional details have not been unveiled yet. The research is expected to help software developers to improve intercooperation between user and computer by means of developing interesting applications adjusted to a user’s mood. The technology has already been patented. Moreover Professor Jenkins has launched a startup. In the nearest future it’s expected a similar technology will be applied to smartphones.
