In the field of virtual reality and teleoperation, haptic interaction between human operator and a computer or telerobot plays an increasingly important role in performing delicate tasks, such as robotic telesurgery, virtual reality based training systems for surgery, virtual reality based rehabilitation systems (Dario et al, 2003) (Taylor, Stoianovici, 2003) (Popescu, et al, 2000), etc. These ...

Effects of Haptic and 3D Audio Feedback on Operator Performance and Workload for Quadrotor UAVs in Indoor Environments Robert M. Philbrick Department of Mechanical Engineering, BYU Master of Science Indoor flight of unmanned aerial vehicles (UAVs) has many applications in environments in which it is undesirable or dangerous for humans to be, such as military reconnaissance or searching for trap...

Collaborative haptic environments, multimodal interaction and communication, hand over task, experiment. Object manipulation is an important activity in everyday life that can also be performed in virtual environments. In the study presented here the extent to which haptic force feedback improves performance when a person hands over a virtual object to another is investigated. Joint manipulatio...

Haptic interfaces that present force and tactile feeling have been utilized in the areas of telemanipulation (Ivanisevi & Lumelsky, 2000; Elhajj et al., 2001), interaction with micro/nano scale phenomena (Ando et al., 2001; Marliere et al., 2004), medical training and evaluation (Langrana et al., 1994; Basdogan et al., 2001), and so on. Haptic interfaces are key devices in constructing virtual ...

The haptic sensations one feels when interacting with physical objects create a rich and varied impression of the objects, allowing one to gather information about texture, shape, compressibility, and other physical characteristics. The human sense of touch excels at sensing and interpreting these haptic cues, even when the object is felt through an intermediary tool instead of directly with a ...

The research presented in this thesis describes a substantial part of the design of a prototypical surgical training simulator. The results are intended to be applied in future simulators used to educate and train surgeons for bone milling operations. In earlier work we have developed a haptic bone milling surgery simulator prototype based on three degrees-of-freedom force feedback. The contrib...

Real-time, plausible visual and haptic feedback of deformable objects without shape artifacts is important in surgical simulation environments to avoid distracting the user. We propose to leverage highly parallel stream processing, available on the newest generation graphics cards, to increase the level of both visual and haptic fidelity. We implemented this as part of the University of Florida...

Passive haptic feedback is very compelling, but a different physical object is needed for each virtual object requiring haptic feedback. I propose to enhance passive haptics by exploiting visual dominance, enabling a single physical object to provide haptic feedback for many differently shaped virtual objects. Potential applications include virtual prototyping, redirected walking, entertainment...
