On the Ability of Humans to Haptically Identify and Discriminate Real and Simulated Objects
2005
Presence - Teleoperators and Virtual Environments
Preserved Fulltext
The ability of human subjects to identify and discriminate between different-sized real objects was compared with their ability to identify and discriminate between differentsized simulated objects generated ...
Interestingly, significant variations in the fidelity of the haptic simulation do not appear to significantly alter the ability of a subject to identify or discriminate between the types of simulated objects ...
