Title: Building Hierarchical Scene Representations from and for Human-Robot Interaction
Abstract: The ultimate goal of human-robot interaction is to enable the robot
to seamlessly communicate with a human about natural everyday environments.
While most research in this area is concentrating on the communicative
cues itself, it is frequently underestimated that the success of
communication heavily relies on the compatibility of the representations
behind it. If a speaker refers to an object or scene structure that the
robot does not perceive or perceives differently, the robot cannot react,
appropriately. In my talk, I will discuss different approaches how
relevant scene structure (like functional room areas, tables, shelves, doors,
etc.) can be learned from coarse shape representations and human-robot
interaction. The techniques are based on the processing of depth data
and include holistic representations, the analysis of scene changes over
time, verbal descriptions, and mixed-initiative dialog.
