Closed-Loop Haptic Feedback Control Using a Self-Sensing Soft Pneumatic Actuator Skin.

Abstract: In this article, we achieve a closed-loop control over haptic feedback, first time for an entirely soft platform. We prototyped a novel self-sensing soft pneumatic actuator (SPA) with soft strain s...

Synchronization of haptic effect data in a media transport stream

Abstract: Haptic information in a series of frames of a media file is identified and time stamps corresponding thereto are determined in accordance with information embedded in a tag either preceding or appending the media file The haptic effect information is automatically synchronized to the media file based on the information in one or more frames of the tag, whereby an actuator outputs the defined haptic effects in the tag in a manner synchronized with corresponding audio and/or video content of the media file

Systems And Methods For Providing Haptic Effects

Abstract: Systems and methods for providing haptic effects are disclosed. For example, one disclosed system includes a computer-readable medium having program code, the program code including program code defining a haptic widget. The haptic widget includes program code defining a haptic effect; program code defining an interface for the haptic widget; program code for receiving, via the interface, a configuration of at least one parameter of the haptic widget; program code for receiving, via the interface, a play command for the haptic effect; and program code for outputting, via the interface, a signal configured to cause the haptic effect, the signal based on the at least one parameter and in response to the play command.

Sensory Subtraction in Robot-Assisted Surgery: Fingertip Skin Deformation Feedback to Ensure Safety and Improve Transparency in Bimanual Haptic Interaction

Abstract: This study presents a novel approach to force feedback in robot-assisted surgery. It consists of substituting haptic stimuli, composed of a kinesthetic component and a skin deformation, with cutaneous stimuli only. The force generated can then be thought as a subtraction between the complete haptic interaction, cutaneous, and kinesthetic, and the kinesthetic part of it. For this reason, we refer to this approach as sensory subtraction. Sensory subtraction aims at outperforming other nonkinesthetic feedback techniques in teleoperation (e.g., sensory substitution) while guaranteeing the stability and safety of the system. We tested the proposed approach in a challenging 7-DoF bimanual teleoperation task, similar to the Pegboard experiment of the da Vinci Skills Simulator. Sensory subtraction showed improved performance in terms of completion time, force exerted, and total displacement of the rings with respect to two popular sensory substitution techniques. Moreover, it guaranteed a stable interaction in the presence of a communication delay in the haptic loop.

Electrotactile haptic display on the fingertips: preliminary results

Abstract: Electrical stimulation of the sense of touch may be used to display pictorial information to blind computer users via a fingertip-scanned (haptic) touch tablet containing embedded electrodes. This might be particularly useful to users of systems with graphical user interfaces, or with drawing and layout software. Electrotactile (electrocutaneous) stimulation on the fingertip, however, differs substantially from that on other body locations. We discuss the implications of designing a practical graphics haptic display by addressing the high-resistance and variable nature of the fingertip electrode-skin interface. >
