Models of and Experiments with Reaching Tasks in Haptic Virtual Environments

Abstract

AbstractThe paper presents an analysis of human reaching movements in manipulation of flexible objects. To predict the trajectory of human hand we resort to two models, the lowest polynomial order model for the hand movement and the minimum hand jerk model. First, we derive analytical solutions for these models for the dynamic environment represented by a multi-mass linear flexible object. Then, we present experimental results obtained with the use of a haptic interface. It is shown that the lowest polynomial order model does not fit with the experimental data while the prediction by the minimum hand jerk criterion matches the experimental patterns with reasonable accuracy.KeywordsHuman movementsreaching taskdynamic environmentmodelinghaptic interface
