Evaluating haptics and 3D stereo displays using Fitts´ law

This paper describes research performed at the BioRobotics lab at Stanford University on the development of a visio-haptic workstation for surgical simulation. This study focuses on the design tradeoffs and choices that must be made to successfully combine 3D stereo with haptic feedback to enable immersive interaction with simulated surgical environments. Specifically, the study concentrates on building a matrix for evaluating 3D stereo haptic workstations. This research attempts to make quantitative comparisons by using Fitts´ Law and positioning test. This paper demonstrates that these methods are applicable to the evaluation of visio-haptic workstations and suggests directions for future research.
