The present study makes two contributions to the literature on tactile feedback. First, it investigates the effect of tactile feedback in isometric rate control devices. The use of tactile feedback in this type of device has not been systematically investigated. An isometric joystick, such as the IBM TrackpointTM in-keyboard pointing device does not perceptibly move and is operated by force. Ca...

BACKGROUND Robotic surgery has gained wide acceptance due to minimizing trauma in patients. However, the lack of tactile feedback is an essential limiting factor for the further expansion. In robotic surgery, feedback related to touch is currently kinesthetic, and it is mainly aimed at the minimization of force applied to tissues and organs. Design and implementation of diagnostic tactile feedb...

Tactile Sensing In article number 2300042, Iris Andrussow, Huanbo Sun, Katherine J. Kuchenbecker, and Georg Martius introduce a miniaturized soft sensor that can give autonomous robots vibrant tactile sensing for safe interactions in the real world. Minsight delivers high-resolution spatially distributed 3D force information using single camera, colored internal lighting, end-to-end learning. I...

This document describes the hardware design of a tactile shear force display. The design parameters have been chosen by inquiries of psychophysical requirements and available actuator technologies. Furthermore the hardware setup of the prototype is described. This display will be used to investigate the perceptual effects of shear force to the human finger pulp.

Human perceptual properties have been applied for designing multisensory display technologies. This paper overviews the sensory-illusion-based approach we have used to create a force display that elicits illusory continuous force sensation by presenting asymmetric vibrations and a self-motion display based on a cross-modal effect between visual and tactile motion.

The present paper presents a finite element model and analysis for the interaction between a piezoresistive tactile sensor and biological tissues. The tactile sensor is proposed for use in minimally invasive surgery to deliver tactile information of biological tissues to surgeons. The proposed sensor measures the relative hardness of soft contact objects as well as the contact force. Silicone r...

Spinal cord injury (SCI) impairs sensory systems causing allodynia. To identify cellular and molecular causes of allodynia, sensitive and valid sensory testing in rat SCI models is needed. However, until recently, no single testing approach had been validated for SCI so that standardized methods have not been implemented across labs. Additionally, available testing methods could not be implemen...

The rapid development of the automobile industry has resulted in many vehicles, increased traffic, and frequent accidents. complexity road conditions is a major contributor to occurrence traffic Drivers are distracted hence unable fully observe all information make optimal timely driving decisions. This study proposes an auxiliary steering control system with force/tactile guidance (ASCFT) its ...

The aim was to investigate tactile discrimination performance under various active and passive conditions and explore the influence of visual information. Participants had to discriminate the direction of lateral pin strokes on their fingertip under three conditions. In one condition (" static ") only tactile stimulation was provided. In a second condition (" active ") the shear force device wa...
