Enabling multi-finger, multi-hand virtualized grasping
This paper presents a series of kinematic and haptic analyses which lead to the design of a particularly simple, yet useful multi-hand multi-finger haptic interface. We also discuss rendering issues which must be addressed in utilizing it, including and extension of the proxy to more general
متن کاملMulti-Finger Interaction and Synergies in Finger Flexion and Extension Force Production
The aim of this study was to discover finger interaction indices during single-finger ramp tasks and multi-finger coordination during a steady state force production in two directions, flexion, and extension. Furthermore, the indices of anticipatory adjustment of elemental variables (i.e., finger forces) prior to a quick pulse force production were quantified. It is currently unknown whether th...
متن کاملControl of a Multi-finger Prosthetic Hand
Our novel prosthetic hand is controlled by extrinsic flexor muscles and tendons of the metacarpal-phalangeal joints. The hand uses tendon-activated pneumatic (TAP) control and has provided most subjects, including amputees and those with congenital limb absence, control of multiple fingers of the hand. The TAP hand restores a degree of natural control over force, duration, and coordination of m...
متن کاملHand Grasping Synergies As Biometrics
Recently, the need for more secure identity verification systems has driven researchers to explore other sources of biometrics. This includes iris patterns, palm print, hand geometry, facial recognition, and movement patterns (hand motion, gait, and eye movements). Identity verification systems may benefit from the complexity of human movement that integrates multiple levels of control (neural,...
متن کاملEye-dominance, writing hand, and throwing hand.
Handedness and eye-dominance are undoubtedly associated statistically, although a previous meta-analysis has found that the precise relationship is difficult to explain, with about 35% of right-handers and 57% of left-handers being left eye dominant. Of particular difficulty to genetic or other models is that the proportions are distributed asymmetrically around 50%. The present study asked whe...
