The Emotion Measurement in iMotions’ technology is based on the INTERPRETATION OF EYE REACTIONS collected via camera and analyzed in a specially designed software. PUPIL DYNAMICS, BLINK CHARACTERISTICS AND GAZE BEHAVIOR are among the Eye Reactions interpreted by the iMotions Emotion Measurement System in order to assess and calculate an index of the IMMEDIATE EMOTIONAL RESPONSE. Check this slideshow for a typical Q&A for most clients. You will here have a lot of referals to related papers.

  • 1. Theore8cal  background  and  research  for  iMo8ons  -­‐  Emo8on  Technology Quantifying Emotion by analyzing Eye properties! WHAT  IS  THE  EMOTION  MEASUREMENT  IN IMOTIONS  EMOTION  TECHNOLOGY  BASED  ON The  Emo8on  Measurement  in  iMo8ons’  technology   ? is  based  on  the  INTERPRETATION  OF  EYE  REACTIONS   collected  via  a  camera  and  analyzed  in  a  specially   designed  soLware. PUPIL  DYNAMICS,  BLINK  CHARACTERISTICS  AND   GAZE  BEHAVIOR  are  among  the  Eye  Reac8ons   interpreted  by  the  iMo8ons  Emo8on  Measurement   System  in  order  to  assess  and  calculate  an  index  of   the  IMMEDIATE  EMOTIONAL  RESPONSE.

  • 2. ? Theore8cal  background  and  research  for  iMo8ons  -­‐  Emo8on  Technology Quantifying Emotion by analyzing Eye properties! “Look  into  a  person’s  pupils,  he  cannot  hide  himself.” WHY  MEASURE  PUPIL  DYNAMICS (Confucius,  551-­‐478  B.C.) It  is  found  that  the  PUPIL  dilates  and  subtracts  not   only  from  light,  but  also  as  a  consequence  of   emo8ons  (Hess,  1972). Pupil  dila8on  has  been  coupled  with  ac8va8on  of   the  sympathe8c  nervous  system  (Granholm  &   Steinhauer,  2004;  Steinhauer  et  al.,  1983).  However,   the  rela8onship  is  complex  because  pupil  size  is  also   related  to  cogni8ve  processing  load  (Beaey  &   Lucero-­‐Wagoner,  2000;  Staners  et  al.,  1979)  and  the   amount  of  light  or  hue  in  visual  s8muli  (Granholm  &   Steinhauer;  2004). The  iMo8ons  system  iden8fies  several  emo8onal   fingerprints  from  the  pupil  based  on  prior  and   proprietary  knowledge.    The  iMo8ons  system   compensates  for  reac8ons  caused  by  the  light  reflex   and  because  the  system  determines  the  emo8onal   reac8on  pre-­‐cogni8ve  the  impact  from  the  cogni8ve   Jakob de Lemos Inventor of the emotion measurement system processing  can  be  iden8fied  and  controlled.

  • 3. ? Theore8cal  background  and  research  for  iMo8ons  -­‐  Emo8on  Technology Quantifying Emotion by analyzing Eye properties! Percep8on  and  the  eye  have  been   WHY  MEASURE  BLINK  CHARACTERISTICS extensively  studied  the  last  100   years!   BLINK  is  also  related  to  emo8onal  as  well  as cogni8ve  reac8ons,  for  example  with  defensive   reac8ons  like  emo8on-­‐modulated  eye  blink  startle,   emo8onal  arousal  and  pleasure  (Bradley,  et  al.,  1999,   Dichter  et  al.,  2002,  Ruiz-­‐Padial  &  Sollers,  2003). The  iMo8ons  system  iden8fies  several  emo8onal   fingerprints  from  the  characteris8cs  based  on  prior   and  proprietary  knowledge.    Because  blinks  are  also   protec8on  mechanisms  to  keep  the  eyeball  protected   the  iMo8ons  system  compensates  for  blink-­‐like   reac8ons  caused  by  the  cleaning/protec8ve  blink   reflex  and  because  the  system  determines  the   emo8onal  reac8on  pre-­‐cogni8ve  the  impact  from  the   cogni8ve  processing  can  be  iden8fied  and  controlled.

  • 4. ? Theore8cal  background  and  research  for  iMo8ons  -­‐  Emo8on  Technology Quantifying Emotion by analyzing Eye properties! WHY  MEASURE  GAZE  BEHAVIOR “The  Eye  is  the  Mirror  of  the  soul.” (Proverb) GAZE  paeerns  are  linked  to  emo8onal  as  well  as   cogni8ve  reac8ons  (Calvo  &  Lang,  2004).   The  iMo8ons  system  iden8fies  several,  pre-­‐ aeen8on  and  cogni8ve  characteris8cs  within  the   gaze  paeerns  based  on  prior  and  proprietary   knowledge.    Because  the  gaze  paeerns  aeen8on   wise  are  influenced  by  the  complexity  of  the  objet (s)  observed,  the  iMo8ons  system  compensates  for   this  effect  when  iden8fying  the  emo8onal   components.
