Predicting precision grip grasp locations on three-dimensional objects by Klein, Lina K, Maiello, Guido, Paulun, Vivian C, Fleming, Roland W

“…We rarely experience difficulty picking up objects, yet of all potential contact points on the surface, only a small proportion yield effective grasps. Here,…”

Visually inferring elasticity from the motion trajectory of bouncing cubes by Paulun, Vivian C., Fleming, Roland W.

“…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…”

Shape, motion, and optical cues to stiffness of elastic objects by Paulun, Vivian C, Schmidt, Filipp, van Assen, Jan Jaap R, Fleming, Roland W

“…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?…”

Effects of material properties and object orientation on precision grip kinematics by Paulun, Vivian C., Gegenfurtner, Karl R., Goodale, Melvyn A., Fleming, Roland W.

“…Successfully picking up and handling objects requires taking into account their physical properties (e.g., material) and position relative to the body. Such…”

The material-weight illusion disappears or inverts in objects made of two materials by Paulun, Vivian C, Buckingham, Gavin, Goodale, Melvyn A, Fleming, Roland W

“…The material-weight illusion (MWI) occurs when an object that looks heavy (e.g., stone) and one that looks light (e.g., Styrofoam) have the same mass. When…”

Inferring the stiffness of unfamiliar objects from optical, shape, and motion cues by Schmidt, Filipp, Paulun, Vivian C, van Assen, Jan Jaap R, Fleming, Roland W

“…Visually inferring the stiffness of objects is important for many tasks but is challenging because, unlike optical properties (e.g., gloss), mechanical…”

Humans Can Visually Judge Grasp Quality and Refine Their Judgments Through Visual and Haptic Feedback by Maiello, Guido, Schepko, Marcel, Klein, Lina K, Paulun, Vivian C, Fleming, Roland W

“…How humans visually select where to grasp objects is determined by the physical object properties (e.g., size, shape, weight), the degrees of freedom of the…”

Integration of prior knowledge during haptic exploration depends on information type by Zoeller, Aaron C, Lezkan, Alexandra, Paulun, Vivian C, Fleming, Roland W, Drewing, Knut

“…When haptically exploring softness, humans use higher peak forces when indenting harder versus softer objects. Here, we investigated the influence of different…”

Object Visibility, Not Energy Expenditure, Accounts For Spatial Biases in Human Grasp Selection by Maiello, Guido, Paulun, Vivian C., Klein, Lina K., Fleming, Roland W.

“…Humans exhibit spatial biases when grasping objects. These biases may be due to actors attempting to shorten their reaching movements and therefore minimize…”
