SURE: Surface Entropy for Distinctive 3D Features,se an entropy-based interest operator that selects distinctive points on surfaces. It measures the variation in surface orientation from surface normals in the local vicinity of a point. We complement our approach by the design of a view-pose-invariant descriptor that captures local surface curvatur

Are Left-Right Hemisphere Errors in Point-to-Origin Tasks in VR Caused by Failure to Incorporate Hearks. However, optic flow displays not only lead to frequent misperceptions of simulated turns, but also to drastic qualitative errors: When asked to point back to the origin of locomotion after viewing simulated 2-segment excursions in VR, between 40% (Riecke 2008) and 100% (Klatzky et al., 1998) o

The Effects of Visual Granularity on Indoor Spatial Learning Assisted by Mobile 3D Information Disp conveyed by these visualization interfaces in order to best support indoor spatial learning has been poorly studied. This experiment investigates how learning of multi-level virtual buildings assisted by mobile 3D displays rendered at different levels of visual granularity effect subsequent unaided

Collaborating in Spatial Tasks: Partners Adapt the Perspective of Their Descriptions, Coordination information affects the representations people spontaneously construct, the description strategies they spontaneously select, and the representations their collaborating partner constructs based on these descriptions.

Using Spatial Analogy to Facilitate Graph Learning,rnessed to help students learn to solve complex graphical reasoning problems. Specifically, we asked whether a brief training experience using spatial analogies could help students learn about .graphs. The basic idea of our intervention was to juxtapose contrastive graphs and encourage students to c

Activity Effects on Path Integration Tasks for Children in Different Environments,six locations subjects stopped and were asked to point into the direction of the path origin with their outstretched arm and finger and later with a mechanical pointer or, in the case of the virtual environment, with a laser pointer. Pointing accuracy was taken as a measure for path integration. Kin
