  Human-robot shared autonomy techniques for vehicle navigation hold promise
  for reducing a human driver's workload, ensuring safety, and improving
  navigation efficiency. However, because typical techniques achieve these
  improvements by effectively removing human control at critical moments, 
  these approaches often exhibit poor responsiveness to human commands---
  especially in cluttered environments. In this paper, we propose a novel 
  goal-blending shared autonomy (GBSA) system, which aims to improve 
  responsiveness in shared autonomy systems by blending human and robot input
  during the selection of local navigation goals as opposed to low-level
  motor (servo-level) commands. We validate the proposed approach by performing
  a human study involving an intelligent wheelchair and compare GBSA to a
  representative servo-level shared control system that uses a policy-blending
  approach. The results of both quantitative performance analysis and a
  subjective survey show that GBSA exhibits significantly better system
  responsiveness and induces higher user satisfaction than the existing
  approach.
