Grasping kinematics are influenced by object shape. Hand orientation and grip aperture adjust early in the movement based on perceived cylinder shape, with final adjustments occurring later.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Human motor control

Background:

  • The visual control of grasping is extensively studied, but the specific impact of shape variations on grasping kinematics remains unclear.
  • Understanding how humans adapt grasping strategies to different object shapes is crucial for robotics and human-computer interaction.

Purpose of the Study:

  • To investigate how variations in elliptical cylinder shape and orientation affect grasping kinematics.
  • To determine the timing of grip aperture and hand orientation adjustments during grasping.

Main Methods:

  • Subjects grasped elliptical cylinders with varying aspect ratios (0.4–1.6) and orientations at different distances (30 and 60 cm).
  • Hand orientation and grip aperture were measured throughout the grasping movement.

Main Results:

  • Hand orientation aligned with principal axes, favoring orientations matching those for circular cylinders.
  • Maximum grip aperture scaled with the selected principal axis length and was larger for longer orthogonal axes.
  • Final hand orientation was predictable from early movement (30% distance), while final grip aperture required later movement information (80% distance).

Conclusions:

  • Perceived object shape guides the selection of grasping locations early in the movement.
  • Grip aperture and hand orientation are progressively refined during the grasping motion based on perceived shape and location.
