Most haptic interfaces are designed with a desire to produce simultaneous perception across multiple senses, with haptic behaviors that complement the task at hand. However, software architectures for haptic interfaces often distribute a virtual model and tasks among multiple processes and CPUs. This functional segregation can reduce the quality of haptic experience, by hiding important details...

The Rutgers Master II-ND glove is a follow up on the earlier Rutgers Master II haptic interface. The redesigned glove has all the sensing placed on palm support, avoiding routing wires to the fingertips. It uses custom pneumatic actuators arranged in a direct-drive configuration between the palm and the thumb, index middle and ring fingers. The supporting glove used in the RMII design is elimin...

For the semester project, we are aiming to develop an intuitive, haptic interface that will allow for improved control over a surgical manipulator designed for application in removal of osteolysis. Current surgical options for osteolysis removal require manual surgery that often leaves much of the lesion unexplored, and, thus, researchers at the Applied Physics Lab and Johns Hopkins University ...

3D virtual environments (VE) require an advanced user interface to fully express their information contents. New I/O devices enable the use of multiple sensorial channels (vision, hearing, touch, etc.) to increase the naturalness and the efficiency of complex interactions. Haptic and acoustic interfaces extend the effective experience of virtual reality to visually impaired users. For these use...

This paper describes experimental studies conducted using a pneumatically driven haptic interface (PHI) system. The PHI is a unilateral exoskeletal device that tracks the motion of the shoulder and elbow. The study was carried out to evaluate the impact of an exoskeletal haptic interface on human perceptional capabilities. A population of twenty subjects participated in a set of experiments tha...

This paper introduces a dial-based haptic interface for a brickout game. Conventionally brickout games are played through a mouse or a keyboard. However, these input devices cannot provide sufficient intuitive interface to move the game paddle or provide multi-modal feedback for the user. We developed a haptic game device that gives the user haptic feedback during the game as well as visual and...

To build a VR training system for visuomotor skills, an image displayed by a visual interface should be correctly registered to a haptic interface so that the visual sensation and the haptic sensation are both spatially and temporally consistent. In other words, it is desirable that what you see is what you feel (WYSIWYF). In this paper, we propose a method that can realize correct visual/hapti...

This paper outlines the development and evaluation of a wearable haptic game interface. The device differs from many traditional haptic feedback implementation in that it combines vibrotactile feedback with gesture based input, thus becoming a two way conduit between the user and the virtual environment. The device is intended to challenge what is considered an “interface” and sets out to purpo...

Human sensory inputs and motor outputs mutually affect one another. We pursue the idea that a tactile interface can influence human motor outputs by intervening in sensory-motor relationships. This study focuses on the shear deformation of a finger pad while a person traces a line or circle. During these tracing movements, the finger pads were deformed using a tactile interface. The tracing dis...

An ergonomical evaluation of a multimodal windows-oriented interface that gives blind and "visually occupied" persons access to graphical user interfaces. Physical models are used to represent interface features providing haptic informations, thanks to a force-feedback device, and nonspeech audio. In the absence of vision, both auditory and haptic modalities are used, to perform manipulation ta...
