Pilot Study

slide-20
SLIDE 20
  • Human-Computer Dialogue

Pilot Study

  • 4 Participants
  • 3D world projected on screen
  • Participants alone in the room
  • Audio interaction
  • 4 Testing conditions
  • Speech detection
  • Speech recognition (limited keywords)
  • Speech recognition (keywords)
  • Human controlled

Setup (Movie)

slide-21
SLIDE 21
  • Human-Computer Dialogue

Pilot Study

  • Used same keywords
  • Spoke longer and more elaborate
  • Responses on content increased realism
  • Waiting time before response decrease realism

Results

Experiment

slide-23
SLIDE 23
  • Human-Computer Dialogue

Experiment

  • 24 participants
  • Dutch, Adults
  • Participant remarks
  • Short avatar introduction of them selves
  • To intensive staring
  • Responses on content increase presence (reported)
  • Delay in response decreased presence (reported)

Setup / remarks

Future improvements

  • Reponses on long answers
  • Allow questions
  • Decrease response times
  • Analyze when speaking
  • Faster protocols
  • Sharper timings
  • More natural avatar movements
  • Anxiety increasing computer responses
