PROBLEM TO BE SOLVED: To provide gesture- and expression-based authentication methods, sensed either in the visible and/or IR spectrum.SOLUTION: A user can define a gesture-based input mode by using respective input values to establish an authentication protocol to unlock a computer or govern other computer behaviors. As an alternative or in addition, the user can define a second input mode based on face recognition plus IR sensing satisfying a threshold to ensure a live person is being imaged for authentication, and/or face recognition plus a particular facial expression such as a smile and wink. |
