SUMMARY:A facial gesture switch using hidden Markov models - Emli-Mari Nel

DESCRIPTION:I will present a system that can identify a facial gesture bas
 ed on duration information and optical flow features. There is a short tra
 ining phase where the user is asked to make his/her gesture three times. A
  hidden Markov model is then used to identify the signal (gesture) by expl
 oiting the fact that the user made the gesture three times. I will show pr
 eliminary results (including an example of a patient with locked-in syndro
 me using the system). This is still work in progress - suggestions will be
  more than welcome.
