Robust Multimodal Interpretation: Interior Decoration Domain (Gaze)



In this study, a static 3D bedroom scene is shown to the user. The system verbally asks the user a list of questions one at a time about the bedroom and the user answers the questions by speaking to the system.

  • The collected data includes users’ speech and accompanying gaze fixations (with possibly selected objects identified by the system).
  • Users’ speech was transcribed.




  • domain_kb.xml

    The domain model file domain model file that defines the properties of each object.

    Each property is annotated with a concept (WordNet synset in the format of <word>#<pos-tag>#<sense-id>). Each object property also has a list of “gold standard” words. The “gold standard” words are the words that the users have used to refer to the objects and their properties (e.g., color, size, shape) during the interaction with the system. The “gold standard” words are manually compiled from all users' speech transcripts and gaze fixations. An example:

    <object name="dresser_desk" id="12">
          <type text="dresser#n#4">desk dresser table vanity</type>

    In the above example, Object dresser_desk (id=12) has one property: type. The concept of property type is dresser#n#4. The gold standard words for property type are: desk, dresser, talbe, vanity.

  • user<id>.xml

    In each user folder, automatically segmented utterances with accompanying gaze fixations, and annotation of referred entities in the utterances.

    An example:

              <entity text="chair_green">0.190656</entity>
              <entity text="door">0.069329</entity>
              <entity text="lamp_bank">0.229842</entity>
              <entity text="dresser">0.510173</entity>
            <transcription>I like the fact that there's a chair in front of the</transcription>

    In the above example, 4 objects (contained in <selection/> tag) were fixated by the user while speaking the utterance. Each fixated object is associated with a probability that is calculated based on temporal length of the gaze fixations. The entity referred by the user’s utterance is object chair_green (contained in <entity_annotation/> tag).

  • user<id>_speech.xml

    Timestamped tokens of the speech transcript.

  • fixation_<id>.txt

    Gaze fixations of user. In the fixation file, the numbers contained in [] are the fixated object ids.
