[HTML][HTML] Shape, motion, and optical cues to stiffness of elastic objects
Nonrigid materials, such as jelly, rubber, or sponge move and deform in distinctive ways
depending on their stiffness. Which cues do we use to infer stiffness? We simulated cubes of …

[HTML][HTML] Inferring the stiffness of unfamiliar objects from optical, shape, and motion cues
Visually inferring the stiffness of objects is important for many tasks but is challenging because,
unlike optical properties (eg, gloss), mechanical properties do not directly affect image …

[HTML][HTML] Effects of material properties and object orientation on precision grip kinematics
Successfully picking up and handling objects requires taking into account their physical
properties (eg, material) and position relative to the body. Such features are often inferred by …

[HTML][HTML] Predicting precision grip grasp locations on three-dimensional objects
We rarely experience difficulty picking up objects, yet of all potential contact points on the
surface, only a small proportion yield effective grasps. Here, we present extensive behavioral …

Grasping objects in immersive Virtual Reality
Grasping is one of the fundamental actions we perform to interact with objects in real
environments, and in the real world we rarely experience difficulty picking up objects. Grasping …

[HTML][HTML] Visually inferring elasticity from the motion trajectory of bouncing cubes
VC Paulun, RW Fleming - Journal of Vision, 2020 - jov.arvojournals.org
Visually inferring the elasticity of a bouncing object poses a challenge to the visual system:
The observable behavior of the object depends on its elasticity but also on extrinsic factors, …

[HTML][HTML] Integration of prior knowledge during haptic exploration depends on information type
When haptically exploring softness, humans use higher peak forces when indenting harder
versus softer objects. Here, we investigated the influence of different channels and types of …

Center or side: biases in selecting grasp points on small bars
VC Paulun, U Kleinholdermann… - Experimental brain …, 2014 - Springer
Choosing appropriate grasp points is necessary for successfully interacting with objects in
our environment. We brought two possible determinants of grasp point selection into conflict: …

[HTML][HTML] Visual search under scotopic lighting conditions
When we search for visual targets in a cluttered background we systematically move our
eyes around to bring different regions of the scene into foveal view. We explored how visual …
