    The effect of incongruent delay on perception of object stiffness via guided haptics
    (2012) Ferrari, Simon William; Hu, Yaoping
    As the world becomes networked new methods of communication between people will become available. Virtual reality technology is already used in the training of various jobs because of the safety and additional tools provided over traditional training methods. Networking remote users to allow them to interact within a virtual environment creates new and improved methods of training and communication. This Master's thesis examined how such a networked virtual environment could handle soft deformable objects, like those found in a surgical training simulation. Soft objects provide a new challenge for interaction within a networked haptic (touch) environment; their changing geometry required bandwidth management and selecting an appropriate interaction scheme. Two empirical studies were conducted to examine the effect on perception of incongruent delay between visual and haptic feedback, which could result from bandwidth management. These results and the developed platform will be used in future research for remote haptic training systems.
