A study of hybrid Virtual Fixtures in assistive path following problems

It has been shown that Virtual Fixtures (VF) can embed multi-modal properties that can be configured in assisting users in enhancing their skills in tasks such as path assembly and path following problems. However, proper description and assembly of VF and the feasibility of their multi-modal cues for guiding tasks remain challenging objectives. In this paper, we present a general framework for assembly and assessment of VF in path following tasks. The paper also presents preliminary user study which investigates the effectiveness of various cues associated with VFs in an assistive path following problem.
