We propose that an important aspect of human-robot interaction is perspective-taking. We
show how perspective-taking occurs in a naturalistic environment (astronauts working on a …

This paper presents a general framework to integrate a new type of constraints, based on
spatial relations, in deformable models. In the proposed approach, spatial relations are …

Providing route directions is a complicated interaction. Utterances are combined with
gestures and pronounced with appropriate timing. This study proposes a model for a robot …

Hand-Drawn sketches are natural means by which abstract descriptions of environments
can be provided. They represent weak prior information about the scene, thereby enabling a …

Medical image segmentation is typically performed manually by a physician to delineate
gross tumor volumes for treatment planning and diagnosis. Manual segmentation is …

Many navigation systems for mobile robots use a metrical map for localization and trajectory
planning. In several situations, however, building such a map upfront is hard or even …

This paper addresses the suitability of different cartographic design variants for visually
communicating recommended routes. We performed a user study, investigating the potential …

In human to human communication, a hand-drawn route map is often sketched to show a
desired navigation path. In this paper, we describe a PDA sketching interface that can be …

In this paper, we present an approach for modeling and comparing small sets of 2-D objects
based on their spatial relationships. This situation can arise in the conflation of a hand-or …

A robotic chauffeur should reason about spatial information with a variety of scales,
dimensions, and ontologies. Rich representations of both the quantitative and qualitative …
