A foot specialized for grasping small branches with a divergent opposable hallux (hallucal grasping) represents a key adaptive complex characterizing almost all arboreal non-human euprimates. Evolution of such grasping extremities probably allowed members of a lineage leading to the common ancestor of modern primates to access resources available in a small-branch niche, including angiosperm pr...

Abstract. In this paper we address the problem of finding an initial good grasping point for the robotic manipulation of textile objects lying on a flat surface. Given as input a point cloud of the cloth acquired with a 3D camera, we propose choosing as grasping points those that maximize a new measure of wrinkledness, computed from the distribution of normal directions over local neighborhoods...

Dynamic handgrip recognition is a new biometric authentication method based on the human grasping behavior. Handgrip pattern recognition seeks to analyze the dynamics inherent in grasping behavior such as how the pressure varying during the grasping process. A real-time biometric system based on handgrip pattern is proposed for aircraft pilot identification in this paper. An experiment was init...

A device that provides quantitative assessment of the grasping function and allows grasping function improvements to be monitored over time can potentially be very useful for hand surgeons, physiotherapists and occupational therapists. A Dynamic Grasping Assessment System (DGAS) that is capable of measuring finger forces during wrist extension, flexion, adduction and abduction was developed. Th...
