Passive Realization of Nonlinear Virtual Environments

Abstract

Passivity theory applied to haptics is for the most part restricted to the case of linear, one-dimensional virtual environments. Here, the application of passivity theory is extended to account for nonlinear, multidimensional, non-conservative virtual environments with quantization and delay. To analyze these more general cases, the notion ofpassive realization, stricter than passivity, is introduced. This notion is exemplified with multidimensional linear virtual environments and with experiments involving nonlinear environments.
