    • Natural  User  Interface  (NUI):   A  new  era  for  the   Human  Computer  Interac:on   Arizona  State  University  
    • 1.     THE  COMPUTER  FROM  THE  HUMAN  POINT  OF  VIEW  
    • It  is  a  box  
    • …  with  a  lot  of  things  inside      C  /  C++      Java      PHP      Ajax      Drupal      Security      3D  Games      AI  
    • …  and  networking      IPv6      Protocols      Security      Wi-­‐Max      Internet  
    • …  a  complete  virtual  world      Cloud            compuPng      Web  2.0      Parallel          compuPng      VirtualizaPon      Ubiquitous      compuPng  
    • computers   •   They  are  intelligent  things   •   They  are  able  to  communicate            among  them   •   They  get  smaller  and  smaller        everyday

    • vision  -­‐  based   ?  
    • facial  analysis     Based  on  a  MIT  Media  Lab  project  soVware  MindReader  API  that  enables  the   real  Pme  analysis,  tagging  and  inference  of  cogniPve  affecPve  mental  states   from  facial  video.       This  framework  combines  vision-­‐based  processing  of  the  face  with  predicPons   of  mental  state  models  to  interpret  the  meaning  underlying  head  and  facial   signals  overPme.       (Ekman  and  Friesen  1978)  –  Facial  Ac:on  Coding  System,  46  ac:ons  (plus  head   movements).     Standard  to  systemaPcally  categorize  the  physical  expression  of  emoPons,  and  it   has  proven  useful  to  psychologists  and  to  animators.
