Control strategies and perception effects in co-located and large workspace dynamical encountered haptics

The present work focuses on perceptual control of haptic manipulation during high frequency interaction with mobile objects. In particular in this work we focused on the analysis of the control and perceptual issues in the throwing and catching in juggling. A training multimodal system that exploits the concepts of co-located visuo-haptic feedback and encountered interfaces was implemented. Using such a system the user juggles with a number of virtual balls that are in contact with him from catch to throw. The control design of the system has been supported by a psychometric validation of the catch contact.
