Single cell magnetorheological fluid based tactile display
A tactile display is a programmable device whose controlled surface is intended to be investigated by human touch, as a finger is dragged over it. It has a great number of potential applications in the field of virtual reality and elsewhere. In this research, a prototype tactile display incorporating magnetorheological (MR) fluid has been constructed and investigated. Surface force responses of...
متن کاملDisplay of Haptic Shape at Different Scales
This paper describes three haptic devices which can create the experience of haptic shape, each at a different scale. They operate by causing fingertip deformations that match the scale of the features of the objects being virtually touched. For large objects, shape display is obtained by the movement of the deformed contact area on the skin, for medium objects, display is given by the deformat...
متن کاملHaptic interfaces based on magnetorheological fluids
In this paper we present an innovative application of magnetorheological (MR) fluids to haptic interfaces. These materials consist of a suspension of a micron-sized, magnetizable particles in a synthetic oil. Exposure to an external magnetic field induces in the fluid a change in rheological behaviour turning it into a near-solid in few milliseconds. Just as quickly, the fluid can be returned t...
متن کاملVisuo-Haptic Display Using Head-mounted Projector
This paper proposes a novel ‘Visuo-Haptic Display’ using a Head-Mounted Projector (HMP) with X’tal Vision optics. Our goal is to develop the device which enables an observer to touch a virtual object just as it is seen. We describe the detail design of an HMP with X’tal Vision, which is very suitable for Augmented Reality. For instance, the HMP makes almost-correct occlusion relationship betwee...
متن کاملShape Recognition for Capacitive Touch Display
In this paper we present a technique to classify five common classes of shapes acquired with a capacitive touch display: finger, ear, cheek, hand hold, half ear-half cheek. The need of algorithms able to discriminate among the aforementioned shapes comes from the growing diffusion of touch screen based consumer devices (e.g. smartphones, tablet, etc.). In this context, detection and the recogni...
