In this paper we explore state-of-the-art underactuated, compliant robot gripper designs through looking at their performance on a generic grasping task. Starting from a state of the art open gripper design, we propose design modifications, and importantly, evaluate all designs on a grasping experiment involving a selection of objects resulting in 3600 object-gripper interactions. Interested in...

The naturalnessand variety of a touch-based hand gesture interface offers new opportunities for human-computer interaction.Using a new type of capacitive sensor array,a Multi-Touch Surface (MTS) can be createdthat is not limited in size, that can be presented in many configurations, that is robust under a variety of environmental operating conditions, and that is very thin. Typing and gesture r...

A prosthetic finger model, intended to imitate a real human hand and for use in replacing the real index finger of an amputee, is designed using tendons instead of joint motors. A dynamic model of the prosthetic finger model is developed, and a non-chattering robust sliding mode control is applied to make the model follow a certain trajectory. Trajectory planning of the finger model is based on...

The mouse cursor acts as a digital proxy for a finger on graphical displays. Our hands, however, have ten fingers and many degrees of freedom that we use to interact with the world. We posit that by creating graphical cursors that reflect more of the hand’s physical properties, we can allow for richer and more fluid interaction. We demonstrate this idea with three new cursors that are controlle...

Dexterous manipulation relies on modulation of digit forces as a function of digit placement. However, little is known about the sense of position of the vertical distance between finger pads relative to each other. We quantified subjects' ability to match perceived vertical distance between the thumb and index finger pads (dy ) of the right hand ("reference" hand) using the same or opposite ha...

This system provides a novel method for Person verification using hand matching with improved performance in large hand pose variations. Normally hand recognition systems are too complex and needs more datasets and algorithms at each level of processing. The proposed approach introduces a reduced data utilization scheme of providing both identification and authentication from contact free hand ...
