The aim of this project is to prove that the addition of a controllable damper to a haptic interface will allow improved control through the modulation of stiffness, thus improving the haptic experience. This concept is proven through the design, construction and testing of a haptic interface tailored to ‘display’ a virtual drum kit.

When we hold an object while looking at it, estimates from visual and haptic cues to size are combined in a statistically optimal fashion, whereby the "weight" given to each signal reflects their relative reliabilities. This allows object properties to be estimated more precisely than would otherwise be possible. Tools such as pliers and tongs systematically perturb the mapping between object s...

Haptic interaction with the world is manipulation using our sense of touch. The term “haptics” arises from the Greek root haptikos, meaning “able to grasp or perceive.” Haptic interaction with computers implies the ability to use our natural sense of touch to feel and manipulate computed quantities. Haptic computer interaction is a relatively new field that has generated considerable interest o...

We present the results of an experimental study of Haptic Digital Audio Effects with and without force feedback. Participants experienced through a low cost Falcon haptic device two new real-time physical audio effect models we have developed under the CORDIS-ANIMA formalism. The results indicate that the haptic modality changed the user’s experience significantly

Functional magnetic resonance imaging (fMRI) studies have provided ample evidence for the involvement of the lateral occipital cortex (LO), fusiform gyrus (FG), and intraparietal sulcus (IPS) in visuo-haptic object integration. Here we applied 30 min of sham (non-effective) or real offline 1 Hz repetitive transcranial magnetic stimulation (rTMS) to perturb neural processing in left LO immediate...

Haptic sensation of a material can be modulated by its visual appearance. A technique that utilizes this visual-haptic interaction is called as pseudo-haptic feedback. Conventional studies have investigated feedback in situations, wherein user manipulated virtual object using computer mouse, force-feedback device, etc. The present study whether and how it was possible to offer who keystrokes. P...

Haptic representations offer access to graphical information for blind and visually impaired persons. Haptic perception requires active explorative movements, making haptic perception, in contrast to visual perception, sequential and local. In order to improve the information gain during haptic exploration and to compensate its limitations additional information can be conveyed in the auditory ...
