This paper presents a haptic stylus interface with a built-in compact tactile display module and an impact module as well as empirical studies on Braille, button, and texture display. We describe preliminary evaluations verifying the tactile display's performance indicating that it can satisfactorily represent Braille numbers for both the normal and the blind. In order to prove haptic feedback ...

For most of the virtual reality systems, one of the major aims is to provide a vivid interaction platform between the human operators and the haptic devices. Through the user interface, a skillful operator can control the haptic devices to accomplish relatively complicated jobs in realtime. Generally, the main components of a virtual reality system include dynamic simulations, haptic devices an...

This research aims to develop a portable haptic master hand with 20 degrees of freedom (DOF). Master hands are used as haptic interfaces in master-slave systems. A master-slave system consists of a haptic interface that communicates with a virtual world or an end-effector for tele-operation, such as a robot hand. The thumb and fingers are usually modeled as a serial linkage mechanism with 4 DOF...

This project involves the development of a new computer interface based on haptics. Information will be transferred from computer to user mechanically (by touch) instead of visually or aurally. The immediate aim is to provide access for blind sound engineers to the graphics-based computer interfaces currently found in digital sound studios. Access for blind persons to computer applications with...

1. Introduction Haptic rendering enables a user to touch, feel, and manipulate virtual objects through a haptic interface (see Figure 1). The field has shown a significant expansion during the last decade. Since the publication of earlier review papers (Salisbury and Srinivasan, 1997; Srinivasan and Basdogan, 1997), new rendering techniques and several new applications have emerged (see the mor...

A haptic interface controlled in impedance mode should present its user with a uniform force capability matching the human hand. This paper reviews a mechanism design methodology that maximizes a workspace-inclusive isotropy index. Force maximization in coreless or voice-coil motors is also considered in order to maximize haptic interface acceleration. Example designs of a planar 3-DOF haptic m...

Haptic rendering is the process of computing and generating forces in response to user interactions with virtual objects. The interaction modality of haptic feedback gains more and more of importance for simulation tasks in virtual environments. However there are only very few portable haptic interfaces, with which the user can experience in a natural way the sensation of force feedback. The sc...

A haptic interface is a kinesthetic link between a human operator and a virtual environment. This paper addresses fundamental stability and performance issues associated with haptic interaction. It generalizes and extends the concept of a virtual coupling network, an artificial link between the haptic display and a virtual world, to include both the impedance and admittance models of haptic int...
